Crushing Machine and Double Roll Balancing Test in Pineapple Stems and Leaves

This paper describes the pineapple leaf crushing machine in detail, including two-roll structure, structural characteristics, working principle, two-roll processing requirements and dynamic balance testing methods, Knife sharpener and after knife edge knife straight knife with the composition. After fully considering the radial and axial positioning and balancing, the machine can effectively increase the number of hitting, cutting and secondary crushing of the pineapple blades after entering the crushing chamber, achieving the goal of meeting the agronomic requirements of a crushing operation. The testing results showed that the passing rate of pineapple leaf was 98.9% after the crushing and returning machine calibrated by dynamic balance test. The passing rate of pineapple head was 92.4% and the working stability was 89.4%. The unevenness of throwing and The average time to failure was 0.59 and 3.4h, the whole machine showed high reliability, to meet the actual operational needs.

Development of Rubber Fertilizer Machine Based on Visual Monitoring Technology

This article describes in detail the integration of a set of functional, agricultural machinery management agencies, service agencies, and users composed of three linkage management technology. The technology will be fixed-point positioning of agricultural tools, job trajectory, image acquisition, workload calculation, index detection, agricultural management and other functions close in the management of agricultural operations management environment, the macro-management of agricultural machinery, command and control scheduling, operational statistics, development decisions and individual management play a positive role in promoting. Test: Based on the visual monitoring technology, the rubber plant ditching and fertilizing combined operation machine can finish the joint operation of ditching, fertilizing and earthing at one time to achieve the purpose of avoiding the volatilization and loss of the limited water in the soil, thereby improving the fertilizer utilization rate, efficiency, and lowing cost. The machine is equipped with Dongfanghong 804 tractor, ditching depth up to 45cm, productivity 1.63hm2/h, fuel consumption 3.4Kg/hm2, fertilization uniformity 92.3%, the coverage rate is up to 96.9%.

Development of 1SG-230 Type Intelligent Rear-Mounted Subsoiling and Rotary Tillage Combined Machine for Sugarcane Field

In view of the fact that in the sugarcane planting area in southern China, the plow foundation is mainly plowed and the hard plow bottom is formed, and in recent years, there are some problems such as the soil adhesion of soil components, crop stalks and other jamming tools and the high energy consumption of the machine tools in the implementation of conservation tillage techniques. Based on the above problems, we designed the 1SG-230-type rear-mounted subsoiling and rotary tillage combined machine. In this paper, we design and analyze the key components such as the overall mechanism of machine tools, rotary tillage and deep pine, etc., and evaluate the performance of the machine in field experiments with the intelligent subsoiling system.

Destructive Test Analysis of Grinder Under Field in Complicated Agricultural Environment of Leizhou

In this paper, through the understanding of the basic structural features and working principle of the crushing and returning machine, the paper introduces Destructive testing process in detail a high perennial pineapple plant with high intensity and randomness and uniformly distributed shrubs in the fiel; b of the rubberwood land, and the growth of large areas of vines and shrubs within the forestland, with unknown environmental factors; c undergrowth of uncultivated land without main crops and hiding the working environment of construction waste and gravel. Through the comparison analysis of test and test indexes, the crushing and returning machine shows good production efficiency to the environment with stable texture of the working object; the fuel consumption is high and shows poor performance for the working conditions and unstable working conditions of the stability, but in the case of adequate throughput of the object has a better throwing uniformity, while rattan objects affixed to the situation there is not picking up the phenomenon; for high pole object, and the case of crushing overload , can not meet the normal crushing quality requirements.ab working conditions for the flexible working environment, for transmission, transmission systems, connectors require a higher; c working conditions are rigid environment, the blade strength, knife holder and bearing the strength of the rack and other requirements. This disruptive test for the performance of universal crushing machine has a strong practical reference.

Electric Control Principle and Experimental Analysis of Rubber Precision Fertilization

In this paper, aiming at the situation that it is difficult to control the amount of natural rubber fertilizer mechanically, this paper introduces in detail a kind of rubber ditch electric control ditching and fertilization combined operation machine, and its control principle, main structure and characteristics are described. The test: the use of electric control precision fertilization control system to take the first booster and then speed mode, the tractor carrier effectively achieve the Promise speed control knob can basically achieve the rubber fertilization precision control, The precision index reaches 94.3%. The fertilization equipment equipped with the control system matches the 80-horsepower tractor. The ditching depth can reach 22cm, the productivity is 1.23hm2/h, the fuel consumption is 3.1kg/hm2, the fertilization uniformity is 90.3% and the coverage rate is up to 98.0% , can effectively improve production efficiency and reduce production costs.

Testing of Basic Characteristics of Pepper Fresh Fruits and Optimization of Mechanical Parameters

By measuring the physical properties of fresh green peppers and measuring the mechanical properties of the epidermis, the crushed and damaged data of the peel and the nucleus under different working conditions were analyzed. The results showed that using 3% 7.0, soaking in heated waters within 24h with the pretreatment of broken machine and peeler peeling peel fruit of the process steps. Obtained the base of the working clearance of 5.5-6.5mm, the cavity is three times the size of the gradual change model and the mechanical properties of the control in the 5 ~ 40N, you can get better peeling effect and the core is not damaged basic conclusions , Which provided theoretical basis for upgrading and processing of pepper initial processing machinery.
