Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of straw return equipment, and in particular to a straw return residue cleaning device. Background Technology
[0002] Returning crop straw to the field is an agricultural management measure that involves directly or indirectly returning crop straw to the farmland. Its aim is to increase soil organic matter, improve soil structure, and enhance soil fertility, thereby promoting crop growth and increasing yield. There are various methods of straw return, including direct and indirect return, each with its own applicable conditions and effects. By rationally selecting and implementing straw return technologies, soil fertility can be effectively improved, crop growth promoted, environmental pollution reduced, and sustainable agricultural development achieved. Straw residue cleaning devices are mainly used to clean up straw residues in farmland to facilitate subsequent tillage and sowing. These devices are widely used in the straw treatment of crops such as corn, rapeseed, rice, and wheat, effectively clearing straw residues from farmland and facilitating subsequent tillage and sowing.
[0003] Currently, existing straw return and stubble removal devices can only remove and throw straw stubble from the field during stubble removal operations. They cannot collect and process the straw stubble in a unified manner. The thrown stubble still needs to be collected or crushed manually or mechanically later, which greatly increases labor and time costs. Furthermore, the thrown straw stubble may accumulate at the edge of the field or be scattered randomly, resulting in an uneven surface. This can lead to poor seed-soil contact during subsequent sowing operations, reducing the seed germination rate. Utility Model Content

One end of each crushing roller is fixedly connected to a corresponding gear, and the two gears mesh with each other. A third motor is fixedly connected to one side of the crushing chamber, and the output shaft of the third motor is fixedly connected to one of the gears. The model of the first motor is YKK4003-6.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0020] Please combine Figures 1 to 4 The straw return and stubble cleaning device of this embodiment includes: a main body 1, a mounting frame 2 fixedly connected inside the main body 1, a fixed plate 3 rotatably connected to the mounting frame 2, a stubble cleaning roller 4 provided at one end of the fixed plate 3, a first motor 5 fixedly connected to the fixed plate 3, a first synchronous wheel 6 fixedly connected to the output shaft of the first motor 5, a second synchronous wheel 7 fixedly connected to the rotating shaft of the stubble cleaning roller 4, a synchronous belt 8 jointly mounted on the first synchronous wheel 6 and the second synchronous wheel 7, two electric telescopic rods 9 hinged to the mounting frame 2, the telescopic rods of the two electric telescopic rods 9 being hinged to the fixed plate 3, a conveyor belt 11 provided inside the mounting frame 2, a second motor 13 fixedly connected to one side of the mounting frame 2, the rotating shaft of the conveyor belt 11 being connected to the output shaft of the second motor 13, and a crushing device provided inside the main body 1.
[0021] Through the above technical solution, the equipment can not only clean up and throw out straw residues from the farmland, but also collect and crush these straw residues, effectively reducing labor and time costs. The crushed straw residues are evenly spread on the farmland to fertilize the farmland and improve the germination rate of subsequent seeds. The main body 1 of the equipment is equipped with a driver's cab.
[0022] The crushing equipment includes a crushing chamber 14, in which two crushing rollers 15 are rotatably connected. One end of each crushing roller 15 is fixedly connected to a corresponding gear 16, and the two gears 16 mesh with each other. A third motor 17 is fixedly connected to one side of the crushing chamber 14. The output shaft of the third motor 17 is fixedly connected to one of the gears 16. The model of the first motor 5 is YKK4003-6.
[0023] Through the above technical solution, driven by the third motor 17 and the two gears 16, the two crushing rollers 15 can efficiently crush the straw residue, turning it into fertilizer that falls onto the farmland and fertilizes it.
[0024] The mounting frame 2 has two fixed support columns 10, the conveyor belt 11 has multiple baffles 12, and the second motor 13 is model YKK4006-8.
[0025] Through the above technical solution, the two support columns 10 serve to support and fix the fixed plate 3 when it falls, and the multiple baffles 12 serve to prevent the straw residue from falling when the conveyor belt 11 transports it.
[0026] The mounting bracket 2 has a fixed connection to a connecting shaft 18, and three support rollers 19 are rotatably connected to the connecting shaft 18. The three support rollers 19 are adapted to the conveyor belt 11. The model of the third motor 17 is YKK4503-10.
[0027] Through the above technical solution, the three support rollers 19 play the role of supporting the bottom of the conveyor belt 11 and assisting it in rotating when it rotates.
[0028] Both sides of the main body 1 are equipped with track wheels 21 and mudguards 22. Both track wheels 21 are adapted to the corresponding mudguards 22. The electric telescopic rod 9 is model GX-2000H.
[0029] Through the above technical solution, the two track wheels 21 enable the whole equipment to move smoothly on farmland, and the two mudguards 22 play the role of blocking mud and gravel from flying.
[0030] A protective shell 20 is fixedly connected to the fixed plate 3, and the protective shell 20 is compatible with the first motor 5.
[0031] Through the above technical solution, the protective shell 20 serves to protect the first motor 5, the first synchronous pulley 6, the second synchronous pulley 7, and the synchronous belt 8.
[0032] The implementation principle of the straw return and stubble cleaning device in this application embodiment is as follows:
[0033] In use, the straw stubble removal device is driven into the farmland where stubble needs to be removed. Two electric telescopic rods 9 extend and retract, causing the fixed plate 3 to descend. The descent of the fixed plate 3 lowers the stubble removal roller 4 to a suitable height, bringing it into contact with the ground. Then, the first motor 5 is activated. The output shaft of the first motor 5 rotates, driving the first synchronous pulley 6 to rotate. The rotation of the first synchronous pulley 6 drives the synchronous belt 8 to rotate, which in turn drives the second synchronous pulley 7 to rotate, thus removing the straw stubble from the farmland. Simultaneously, the second motor 13 is started, and the output shaft of the second motor 13 rotates, driving the conveyor belt 11 to rotate and transport the cleared straw stubble into the crushing chamber 14. The third motor 17 is started, and the output shaft of the third motor 17 rotates, driving one of the gears 16 to rotate. The rotation of one of the gears 16 drives the rotation of another gear 16, and the rotation of the two gears 16 drives the two crushing rollers 15 to rotate, crushing the straw stubble. The crushed straw stubble falls from the bottom outlet of the crushing chamber 14 and is evenly spread on the farmland as the stubble clearing device moves, turning into fertilizer for the farmland, thus completing the stubble clearing operation.
[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
