Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to a standing corn stalk crushing, kneading and returning machine. Background Technology

[0002] With the deepening of the concept of sustainable agricultural development, returning corn stalks to the field has become an important agricultural measure to improve soil fertility, reduce environmental pollution, and conserve resources. Standing corn stalk crushing and returning machines, because they do not require the stalks to be cut down beforehand, can directly crush and return standing corn stalks to the field, significantly improving operational efficiency and are widely used in corn-growing areas.

[0003] In existing technologies, a large amount of dust generated during the straw crushing process will permeate the working environment, which not only pollutes the environment but also endangers the respiratory health of operators.

[0004] Therefore, it is necessary to invent a standing corn stalk crushing, kneading and returning machine to the field to solve the above problems. Utility Model Content

The bottom of the first transmission rod and the end of the second transmission rod located inside the housing are rotatably connected to the inner wall of the housing. Crushing rollers are fixedly connected to the surfaces of both the first transmission rod and the second transmission rod.

[0009] Preferably, the filter assembly includes a filter box, the bottom of which is fixedly connected to the top of the housing, a dust pump is fixedly installed on the top of the filter box, the air inlet of the dust pump is connected to a connecting pipe, one end of the connecting pipe is connected to a dust suction pipe, the dust suction pipe is located above the feed hopper, and the air outlet of the dust pump is connected to the filter box through a pipe.

A crushing mechanism 7 is provided inside the shell 1, and a feed hopper 8 passes through the top of the shell 1. A filter assembly 9 is fixedly installed on the top of the shell 1.

[0023] A connecting seat (not shown in the figure) is fixedly installed on the rear side of the housing 1 for connecting with an external drive mechanism; a discharge port is opened at the bottom of the housing 1, and the crushed material falls from the discharge port at the bottom of the housing 1 into the field to complete the return to the field.

[0024] The crushing mechanism 7 includes a motor housing 71, one side of which is fixedly connected to one side of the housing 1. A crushing motor 72 is fixedly installed on one side of the inner wall of the motor housing 71. The output shaft of the crushing motor 72 is fixedly connected to a first transmission rod 73. A second transmission rod 74 is rotatably connected to the rear end of one side of the inner wall of the motor housing 71. Transmission gears 75 are fixedly installed on the surfaces of both the first transmission rod 73 and the second transmission rod 74, and the two transmission gears 75 mesh with each other.

[0025] One end of the first transmission rod 73 and the second transmission rod 74 both penetrate the motor housing 71 and the housing 1 and extend into the interior of the housing 1. The bottom of the first transmission rod 73 and the end of the second transmission rod 74 located inside the housing 1 are rotatably connected to the inner wall of the housing 1. Crushing rollers 76 are fixedly connected to the surfaces of the first transmission rod 73 and the second transmission rod 74.

[0026] The filter assembly 9 includes a filter box 91, the bottom of which is fixedly connected to the top of the housing 1. A dust pump 92 is fixedly installed on the top of the filter box 91. The air inlet of the dust pump 92 is connected to a connecting pipe 93. One end of the connecting pipe 93 is connected to a dust suction pipe 94. The dust suction pipe 94 is located above the feed hopper 8. The air outlet of the dust pump 92 is connected to the filter box 91 through a pipe 95.

[0027] A first filter screen 97 and a second filter screen 98 are respectively provided between the top and bottom of the inner wall of the filter box 91 via a U-shaped seat 96. A first dust collection box 99 is provided inside the filter box 91 and on one side of the first filter screen 97. A second dust collection box 910 is provided inside the filter box 91 and on the left side of the second filter screen 98. A door 911 is hinged to the front of the filter box 91.

[0028] The diameter of the filter pores in the second filter screen 98 is smaller than that in the first filter screen 97;

[0029] A ventilation opening is provided on one side of the filter box 91;

[0030] A protective box 10 is fixedly installed on one of the supports 2. A drive motor 11 is fixedly installed inside the protective box 10. The output shaft of the drive motor 11 is fixedly connected to the rotating rod 3.

[0031] The working principle of this practical application is as follows:

[0032] Connect the equipment to an external drive device (such as a tractor), move it to the field to be worked, and start the drive motor 11, the crushing motor 72 and the dust pump 92. The drive motor 11 drives the rotating rod 3 to rotate, and the synchronous wheel 4 on the surface of the rotating rod rotates synchronously. Through the synchronous belt 5, the synchronous wheel 4 on the other side and multiple cutting blades 6 work together. During the slow movement of the equipment, the cutting blades 6 continuously cut the corn stalks standing in the field. The cut stalks are fed into the shell 1 through the feed hopper 8.

[0033] After the crushing motor 72 is started, its output shaft drives the first transmission rod 73 to rotate. The transmission gear 75 on the surface of the first transmission rod 73 meshes with the transmission gear 75 on the surface of the second transmission rod 74, thereby driving the second transmission rod 74 to rotate, causing the two crushing rollers 76 to rotate at high speed. After the straw enters the shell 1, it is squeezed, sheared and kneaded by the two crushing rollers 76 and refined into uniform fragments. The fragments eventually fall from the bottom of the shell 1 to the field to complete the return to the field.

[0034] After the dust pump 92 is started, it generates negative pressure, which is used to absorb the dust generated during the straw crushing process above the feed hopper 8 through the dust suction pipe 94. The dust enters the filter box 91 through the connecting pipe 93 and the pipe 95. The dust first passes through the first filter screen 97, where large dust particles are intercepted and fall into the first dust collection box 99. The remaining fine dust continues to be filtered through the second filter screen 98, and the fine dust particles fall into the second dust collection box 910. The clean air after double filtration is discharged from the vent on one side of the filter box 91.

[0035] After the operation is completed, turn off all motors and dust pump 92, open the front door 911 of filter box 91, and pull out the first dust collection box 99 and the second dust collection box 910 to clean the dust.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
