Description

Technical Field

[0001] This utility model belongs to the field of straw crushing and returning to the field technology, specifically relating to an agricultural machinery and equipment for crushing and returning agricultural straw to the field. Background Technology

[0002] Agricultural straw crushing and returning to the field refers to an agricultural management measure in which crop straw is crushed using agricultural machinery and then directly returned to the field. Specifically, after harvesting crops, farmers use straw crushing equipment to crush the straw on the spot, generally keeping the length within 10 centimeters. Then, the crushed straw is evenly spread on the surface, and finally, tilling machinery is used to plow the straw into the soil.

[0003] Patent CN221335347U discloses "an agricultural machinery device for straw crushing and returning to the field, including a handcart. A box is fixedly installed on the top of the handcart. Through the set filter mechanism and reciprocating mechanism, the U-shaped trough can be frequently swung back and forth during use, throwing impurities in the straw onto the U-shaped trough. The impurities can fall down along the filter holes, achieving the purpose of removing straw impurities. This solves the problem that since straw often contains mortar and gravel from the field, during the straw crushing process, mortar and gravel and other impurities are often poured into the crushing device, which will cause wear on the crushing blades and affect the straw crushing effect."

[0004] Although the existing technology can crush straw, it cannot break up the crushed straw. When the straw is discharged, it tends to clump together and cannot be evenly dispersed into the soil, resulting in poor practicality. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide an agricultural machinery and equipment for crushing and returning agricultural straw to the field in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] An agricultural machinery device for crushing and returning agricultural straw to the field includes a movable box, a screening mechanism installed inside the box for removing sand and gravel from the straw, a crushing mechanism installed inside the box for crushing the screened straw, and a dispersing mechanism installed inside the box for breaking up the clumps of crushed straw. A discharge port is provided at the bottom of one side of the box, and a trapezoidal guide platform is fixedly provided at the bottom of the inner side of the box for feeding the crushed straw into the discharge port. A telescopic mechanism is provided inside the box for driving the screening mechanism to move laterally back and forth. The dispersing mechanism includes a movable rod rotatably located at the bottom of one side of the screening mechanism, a dispersing rod slidably located on the outer wall of one end of the movable rod and located inside the discharge port, and a rotating rod rotatably located at the end of the dispersing rod near the movable rod for rotating the dispersing rod to break up the straw in the discharge port.

[0008] As a further optimization of this utility model, the screening mechanism includes a sieve plate that is movably mounted on the top of the inner side of the box and is inclined, baffles that are fixed on both sides of the top of the sieve plate, and a connecting frame that is fixed on the bottom of the sieve plate.

[0009] As a further optimization of this utility model, a feeding hopper for feeding straw into the top of the screen plate is fixedly provided on the top of the box, and several telescopic rods for supporting and limiting the screening mechanism are fixedly provided between the two sides of the inner wall of the box and the outer wall of the baffle.

[0010] As a further optimization of this utility model, the telescopic mechanism includes an electric push rod fixedly installed between one side of the connecting frame and the inner wall of the box, the movable rod being rotatably connected to one side of the connecting frame, and the rotating rod being fixedly connected to the bottom inner side of the box.

[0011] As a further optimization of this utility model, the crushing mechanism includes two crushing rollers rotatably disposed inside the box and located below the sieve plate, and a motor fixedly installed on the outside of the box for driving the two crushing rollers to rotate.

[0012] As a further optimization of this utility model, the inner wall of the box body away from the screen plate is fixedly provided with a guide plate for feeding straw into the crushing mechanism, and the bottom of the trapezoidal guide platform is provided with a receiving groove for accommodating and allowing the crushing rod to rotate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Driven by the telescopic mechanism, the screening mechanism can be moved to remove sand and gravel from the straw before crushing, making it difficult for sand and gravel to enter the crushing mechanism and damage the internal parts of the crushing mechanism. It can also drive the dispersing rod to rotate around the rotating rod, thereby breaking up the clumps of straw discharged from the discharge port, so that the straw can be more evenly dispersed into the soil, which is convenient and practical.

[0015] 2. The crushing mechanism can crush the straw, allowing it to be returned to the field as soil nutrients. The trapezoidal guide platform guides the crushed straw through the discharge port, making it convenient and quick. The connecting rod connects the connecting frame and the dispersing rod, allowing the screening mechanism, such as the connecting frame, to rotate the dispersing rod after moving laterally, facilitating the dispersing of clumps of straw.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example

[0023] like Figure 1-4 As shown, an agricultural machinery device for crushing and returning agricultural straw to the field includes a movable box 1, a screening mechanism, a crushing mechanism, and a dispersing mechanism. Several casters are fixedly installed at the bottom corner of the box 1. The rolling of the casters facilitates the movement of the box 1 by the staff in the field. After moving in the field, the device can directly disperse the dispersed straw into the soil.

[0024] like Figure 1-3 As shown, the screening mechanism is installed inside the box 1 and is used to screen out sand and gravel from the straw. A door is provided on one side of the box 1 so that the staff can easily remove the sand and gravel that have fallen to the bottom of the box 1 after screening.

[0025] like Figure 2-3As shown, the screening mechanism includes a screen plate 2 that is movably mounted on the top of the inner side of the box 1 and is inclined, baffles 21 that are fixed on both sides of the top of the screen plate 2, and a connecting frame 22 that is fixed on the bottom of the screen plate 2. A feeding hopper 11 for feeding straw into the top of the screen plate 2 is fixedly provided on the top of the box 1. Several telescopic rods 23 for supporting and limiting the screening mechanism are fixed between the inner walls of the box 1 and the outer walls of the baffles 21. The telescopic rods 23 can support and limit the screen plate 2, so that the screen plate 2 can only move laterally within the box 1. The baffles 21 can block the edges on both sides of the screen plate 2. When in use, the operator can feed straw into the top of the screen plate 2 through the feeding hopper 11.

[0026] like Figure 2 As shown, the housing 1 is equipped with a telescopic mechanism for driving the screening mechanism to move laterally back and forth. The telescopic mechanism includes an electric push rod 24 fixedly installed between one side of the connecting frame 22 and the inner wall of the housing 1. The connecting frame 22 can connect the screen plate 2 and the electric push rod 24. After the electric push rod 24 extends and retracts, it will drive the screen plate 2 and other components to move laterally back and forth quickly, so as to remove the sand and gravel in the straw before crushing, making it difficult for the sand and gravel to enter the crushing mechanism and damage the internal components of the crushing mechanism. After screening, the sand and gravel will fall to the bottom of the inner side of the housing 1.

[0027] like Figure 1-3 As shown, the crushing mechanism is installed inside the housing 1 and is used to crush the screened straw. The crushing mechanism includes two crushing rollers 3 rotatably installed inside the housing 1 and located below the screen plate 2, and a motor 31 fixedly installed on the outside of the housing 1 for driving the two crushing rollers 3 to rotate. There can be two motors 31 to drive the two crushing rollers 3 to rotate synchronously in opposite directions. After the two crushing rollers 3 rotate, they can crush the screened straw. The two motors 31 can achieve synchronous rotation through components such as a motion controller. The synchronous rotation of two or more motors is a public technology and will not be described in detail here. The housing 1 has a built-in battery for powering the motors 31 and the electric push rod 24. The battery is a common power supply component in existing equipment. Its specific internal structure and circuit connection have been disclosed and will not be described in detail here.

[0028] like Figure 2-3 As shown, a guide plate 13 for feeding straw into the crushing mechanism is fixedly provided on the inner wall of the end of the box body 1 away from the screen plate 2. The guide plate 13 can feed the straw that has moved from the screen plate 2 to the top of the crushing mechanism back into the top of the crushing mechanism, thereby guiding the straw.

[0029] like Figure 1-3 As shown, a discharge port 12 is provided at the bottom of one side of the box body 1. A trapezoidal guide platform 4 is fixedly provided at the bottom of the inner side of the box body 1 for feeding the crushed straw into the discharge port 12. Through the guide of the trapezoidal guide platform 4, the crushed straw can be discharged from the equipment through the discharge port 12.

[0030] like Figure 2-4 As shown, the dispersing mechanism is installed inside the box 1 and is used to disperse the clumps of crushed straw. The dispersing mechanism includes a movable rod 5 rotatably disposed at the bottom of one side of the screening mechanism, a dispersing rod 51 slidably disposed on the outer wall of one end of the movable rod 5 and located in the discharge port 12, and a rotating rod 52 rotatably disposed at the end of the dispersing rod 51 near the movable rod 5 and used to allow the dispersing rod 51 to rotate and disperse the straw in the discharge port 12. The movable rod 5 is rotatably connected to one side of the connecting frame 22, and the rotating rod 52 is fixedly connected to the bottom inner side of the box 1.

[0031] The box 1 can support and fix the rotating rod 52. The rotating rod 52 can connect the dispersing rod 51 to the box 1, so that the dispersing rod 51 can rotate at the box 1. The connecting frame 22 and the dispersing rod 51 are connected by the movable rod 5. After the screening mechanism such as the connecting frame 22 moves laterally back and forth, it can drive the dispersing rod 51 to rotate back and forth around the rotating rod 52. After rotating, the dispersing rod 51 can disperse the clumps of straw discharged from the discharge port 12, so that the straw can be dispersed more evenly into the soil.

[0032] Furthermore, when the screening mechanism such as the connecting frame 22 moves, the rotating movable rod 5 will adaptively extend and retract within the dispersing rod 51, thereby continuously connecting the connecting frame 22 and the dispersing rod 51. The movable frame 22 is in contact with the bottom of the inner side of the box 1. When the dispersing mechanism such as the dispersing rod 51 rotates, it will push the sand and gravel in the box 1 to both sides and gather them, so that the staff can clean up the gathered sand and gravel in a concentrated manner later.

[0033] like Figure 1 , Figure 2 and Figure 4 The bottom of the trapezoidal guide platform 4 is provided with a receiving groove 41 for accommodating and allowing the dispersing rod 51 to rotate. The receiving groove 41 provides space for the dispersing rod 51 to rotate at the bottom of the trapezoidal guide platform 4, and also facilitates the dispersing rod 51 to pass through the trapezoidal guide platform 4. An elastic partition pad can be provided at the connection between the end of the dispersing rod 51 near the movable rod 5 and the trapezoidal guide platform 4, so that sand and gravel at the bottom of the inner side of the box 1 are not easily entered into the receiving groove 41 of the trapezoidal guide platform 4.

[0034] It should be noted that, in the operation of this agricultural straw crushing and returning equipment, the operator can feed the straw into the top of the screen plate 2 through the feed hopper 11, then control the extension and retraction of the electric push rod 24 and turn on the motor 31. After the electric push rod 24 extends and retracts, it will drive the screen plate 2 and other components to move quickly in a horizontal reciprocating motion, thereby removing the sand and gravel in the straw before crushing, so that the sand and gravel will not easily enter the crushing mechanism and damage the blades and other components inside the crushing mechanism. After screening, the sand and gravel will fall to the bottom of the inner side of the box 1.

[0035] After the motor 31 runs, it will drive the two crushing rollers 3 to rotate synchronously in opposite directions. After the two crushing rollers 3 rotate, they can crush the screened straw. At this time, the crushed straw can slide down to the discharge port 12 through the guide of the trapezoidal guide platform 4.

[0036] Simultaneously, the connection between the connecting frame 22 and the dispersing rod 51 via the movable rod 5 allows the screening mechanism, such as the connecting frame 22, to move laterally back and forth, which in turn drives the dispersing rod 51 to rotate back and forth around the rotating rod 52. After rotation, the dispersing rod 51 can disperse the clumps of straw discharged from the discharge port 12, so that the straw can be more evenly dispersed into the soil. The crushed straw can be returned to the field as soil nutrients, thus carrying out the agricultural straw crushing and returning to the field treatment.

[0037] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
