Description

Tractor-mounted cassava stalk crushing and returning machine

technical field

The utility model relates to an agricultural machine, in particular to a tractor-mounted cassava stalk crushing and returning machine suitable for crushing and returning stalks of stalk-type crops. the

Background technique

Cassava, a stalk-type crop, needs to be cut off part of the cassava stalk before harvesting, whether it is harvested manually or mechanically, leaving only a section of hard stalk 20 to 30 cm above the ground, which is convenient for cassava collection. The man-made cassava stalks are about 150cm long, and there are about 800 to 1,000 plants per mu. These cassava stalks need to be removed from the cassava field and placed on the fields or ridges for natural decomposition, otherwise it will affect the subsequent operations of machines and tools, which requires a lot of Labor will be used to move it, and some fields will be occupied, which will increase the cost of farming. If, by installing a stalk crushing machine in front of the tractor, the stalks can be crushed and placed in the field, it will not only increase the soil organic matter content, improve the soil structure, but also increase the crop yield. the

Utility model content

The purpose of the utility model is to provide a stalk crop grinder arranged in front of the tractor, which crushes the stalks of the crops and places them in the field. the

In order to solve the above technical problems, the technical solution adopted by the utility model is: the front-mounted cassava stalk crushing and returning machine of the tractor includes a crushing frame and a crushing box arranged in front of the tractor, and a motor is arranged on the crushing frame, and the motor passes through the The transmission rod is connected with the crushing shaft arranged vertically in the crushing box, the crushing shaft is provided with radial moving knives, the inner wall of the crushing box is provided with fixed knives intersecting with the moving knives, and the lower end of the crushing shaft is provided with disc cutters. the

The upper end of the crushing box is provided with a baffle. the

A commutator is provided at the junction of the transmission rod and the crushing shaft. the

The motor is a hydraulic motor. the

The moving knife and the fixed knife are arranged in a spiral. the

Due to the adoption of the above-mentioned structure, by installing a stalk grinder in front of the tractor, the stalks are crushed and placed in the field, which can not only increase the content of soil organic matter, improve the soil structure, and increase crop yields, but also save a lot of money spent on cutting. The labor force of dropping and moving the crop stalks greatly improves the farming efficiency and reduces the farming cost. the

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail. As shown in Figure 1, the tractor-mounted cassava stalk crushing and field returning machine described in the utility model includes a crushing frame 11 and a crushing box 3 arranged in front of the tractor, and a hydraulic pump is arranged on the tractor. The output oil pipe is screwed to the motor 1, the motor 1 is a hydraulic motor, and the rotation speed of the motor 1 is manually controlled by the operator of the tractor, which saves a high-cost power device and complicated mechanical transmission. the

The motor 1 is connected to the crushing shaft 6 installed vertically in the crushing box 3 through the transmission rod 2, and the crushing shaft 6 rotates continuously under the drive of the motor 1, so that the disc cutter 9 at the lower end of the crushing shaft 6 first cuts off the crop stalks First, the disc cutter 9 holds the crop stalks that have been cut off, and the movable knife 7 radially provided on the crushing shaft 6 rotates with the crushing shaft 6 to bring the crop stalks that have been cut off to the crushing box 3 . The inner wall of the crushing box 3 is provided with a fixed knife 5 intersecting and staggered with the moving knife 7. The fixed knife 5 will prevent the stalk from continuing to move forward, and the moving knife 7 on the crushing shaft 6 must be driven by the motor 1 to forcibly pass through the fixed knife 5. , thus achieving the purpose of crushing. the

If the movable knife 7 cannot forcefully pass through the fixed knife 5 due to the too hard crop stalks, the commutator 8 provided at the junction of the transmission rod 2 and the crushing shaft 6 will adjust the direction of rotation of the crushing shaft 6 so as to Reduce the impact of crushing to protect the machine tool. The part of the crop stalks higher than the crushing shaft 6 is blocked by the baffle plate 4 provided on the upper end of the crushing box 3, and under the action of gravity, it falls into the crushing box 3 and continues to be crushed. When the crop stalks are crushed to a certain extent, they will pass through the The opening of the smash box 3 falls into the field 10 . the

Both the movable knife 7 and the fixed knife 5 are made of threaded steel to enhance the surface adhesion and make the crushing more thorough. The movable knife 7 and the fixed knife 5 are arranged in a spiral, and the impact is small during crushing, which improves the service life of the machine tool. the

The utility model can be widely used for crushing stalk crops such as cassava stalks, corn stalks and cotton stalks. In a word, although the utility model has exemplified the above-mentioned preferred embodiments, it should be noted that although those skilled in the art can make various changes and modifications, unless such changes and modifications deviate from the scope of the utility model, otherwise all It should be included in the protection scope of the present utility model. the
