Description

Technical Field

[0001] The present application relates to the field of agricultural machinery and equipment, and in particular to a straw crushing and burying device. Background Art

[0002] With the large-scale development of agriculture, returning straw to the fields has become an important means to improve soil fertility. When existing straw crushing and burying machines are in operation, due to the high humidity of the straw or the strong viscosity of the soil, dirt and broken straw are easily attached to the surface of the crushing blades, resulting in blade blunting, reduced crushing efficiency, and even causing the equipment to overload and shut down. Traditional solutions (such as blade coating or periodic manual cleaning) have problems such as high cost and cumbersome operation. In addition, the accumulation of attachments will change the dynamic balance of the blades, aggravating the vibration and wear of the equipment. Therefore, there is an urgent need for a straw processing equipment that can actively prevent attachment and does not require frequent maintenance. Summary of the Invention

The vehicle body 1 can travel in the field, the crushing mechanism 3 can crush the straw in the field, and the burying mechanism 2 includes a rotary cutter and a rotating component (not shown in the figure) that drives the rotary cutter to rotate. The rotating component can be a rotary motor. The burying mechanism 2 is used to bury the straw under the soil.

[0036] Reference Figure 1 and Figure 2 The crushing mechanism 3 includes a shell 31, which is used to connect to the vehicle body 1. A rotating roller 4 is rotatably provided in the shell 31, and a crushing knife 32 is provided on the rotating roller. The shell 31 is an arc-shaped structure. In order to reduce pollution, sealing plates are provided at both ends of the shell 31.

Specifically, the power assembly 35 includes a driving wheel 351, a driven wheel 352, a belt 353 and a power source 354. The driven wheel 352 is fixedly provided at one end of the rotating rod 4, the driving wheel 351 is rotatably provided on the housing 31, and a belt 353 is sleeved between the driving wheel 351 and the driven wheel 352. In one embodiment, the power source 354 is a power motor, and the output shaft of the power motor is fixedly connected to the driving wheel 351. In another embodiment, the power source 354 can be a transmission shaft, and the transmission shaft is connected to the power mechanism of the vehicle body 1, and the power mechanism of the vehicle body 1 can be a gasoline engine or a diesel engine.

[0038] Optionally, refer to Figure 2 and Figure 3, multiple groups of crushing knives 32 are arranged at intervals along the circumference of the rotating roller 4, and each group includes multiple crushing knives 32 arranged at intervals along the axial direction of the rotating roller 4. In this embodiment, four groups of crushing knives 32 are evenly spaced along the circumference of the rotating roller 4. In other embodiments, three groups, five groups or other numbers can be set. Among them, the crushing knives 32 include vertical blades 321 and curved blades 322 arranged on both sides of the vertical blades 321. There is a gap between the curved blades 322 and the vertical blades 321, and the end of the curved blades 322 away from the rotating roller 4 is bent in the direction away from the vertical blades 321. The curved blades 322 cooperate with the vertical blades 321 to effectively improve the crushing effect of the straw, and there is a gap between the curved blades 322 and the vertical blades 321, which increases the crushing area of each group of crushing knives 32, thereby improving the crushing efficiency.

[0039] In order to further improve the crushing effect, the edges of the vertical blade 321 and the curved blade 322 are provided with a serrated structure.

[0040] Optionally, refer to Figure 3 and Figure 4 The crushing knife 32 is provided with a cleaning piece, which is arranged in the gap between the vertical blade 321 and the curved blade 322 to clean the soil or straw attached to the crushing knife 32.

[0041] Specifically, the cleaning member is configured as a cleaning block 33, which is disposed between the vertical blade 321 and the curved blade 322 along the width direction of the vertical blade 321. The opposite side walls of the cleaning block 33 respectively abut against the vertical blade 321 and the curved blade 322. A groove 331 is formed along the length of the cleaning block 33 on the side wall away from the rotating roller 4 to facilitate scraping away dirt and straw from the side walls of the curved blade 322 and the vertical blade 321.

[0042] Optionally, several groups of ear plates 41 for mounting the crushing blade 32 are fixedly provided on the rotating roller 4, each group of ear plates 41 includes two ear plates 41, and a pin 5 is detachably provided between the two ear plates 41, and the vertical blade 321 and the curved blade 322 are sleeved on the pin 5.

[0043] Reference Figure 4A limiting ring 51 is sleeved on the latch 5 between the curved blade 322 and the vertical blade 321, and both ends of the latch 5 are threadedly connected to a limiting nut 52. An elastic portion 53 is provided between the limiting nut 52 and the curved blade 322 for pressing against the curved blade 322. The elastic portion 53 can be a spring or a rubber ring with a certain elastic deformation ability. During the rotation of the crushing knife 32, if a hard object such as a stone is squeezed between the curved blade 322 and the vertical blade 321, the curved blade 322 can be squeezed and move a short distance along the latch 5 to increase the distance between the two curved blades and the vertical blade 321, preventing the stone from getting stuck between the curved blade 322 and the vertical blade 321, and preventing the stone from damaging the curved blade 322 and the vertical blade 321.

[0044] Optionally, refer to Figure 3 and Figure 4 The driving mechanism is connected to the cleaning member and is used to drive the cleaning member to slide along the radial direction of the rotating roller 4 to clean up the soil or straw attached to the crushing knife 32.

[0045] The drive mechanism includes a drive rod 341, a drive plate 342, a reset member 343, and a drive assembly. The rotating rod 4 is hollow, and the drive rod 341 is inserted into the rotating rod 4 and slides radially along the rotating rod 4. The end of the drive rod 341 passes through the rotating rod 4 and is fixedly connected to the cleaning block 33. The drive plate 342 is axially disposed within the rotating rod 4. A plurality of wedge blocks 3421 are fixedly disposed on the drive plate 342 for contacting the top of the drive rod 341. The number of wedge blocks 3421 corresponds to the number of pulverizing blades 32 in each group. The sidewalls of the wedge blocks 3421 adjacent to the pulverizing blades 32 are inclined. A spherical portion is disposed on the top of the drive rod 341, which contacts the inclined surface of the wedge blocks 3421. When the drive plate 342 moves, it can drive the wedge blocks 3421 to squeeze the drive rod 341, thereby driving the drive rod 341 toward the outside of the rotating rod 4.

[0046] The reset member 343 is used to drive the driving rod 341 into the rotating shaft 4. The reset member 343 is a reset spring, which is mounted on the driving rod 341. The driving rod 341 is fixed with a fixing base 3411. One end of the reset spring abuts the fixing base 3411, and the other end abuts the inner wall of the rotating shaft 4. When the wedge block 3421 is out of contact with the driving rod 341, the reset spring drives the driving rod 341 into the rotating shaft 4, thereby driving the cleaning block 33 to move to the end of the crushing blade 32 closest to the rotating shaft 4, preventing the cleaning block 33 from interfering with the crushing operation of the crushing blade 32.

[0047] Optionally, a drive disk 6 is provided at one end of the rotating rod 4 so as to slide axially along the rotating rod 4, one end of multiple drive plates 342 is fixedly provided on the drive disk 6, a vertical plate 311 is fixedly provided on the shell 31, and the drive disk 6 is provided on the vertical plate 311 so as to slide axially along the rotating rod 4, and the drive disk 6 contacts the end of the drive plate 342 extending outside the rotating rod 4.

[0048] The drive assembly is used to drive the drive plate 6 to reciprocate along the axial direction of the rotating rod 4. The drive assembly includes a drive motor 3441, a compression spring, and a cam 3442. The drive motor 3441 is fixedly mounted on the vertical plate 311, and the cam 3442 is fixedly mounted on the output shaft of the drive motor 3441. The compression spring (not shown) is disposed within the rotating rod 4 at the end of the drive plate 342 away from the drive motor 3441. One end of the compression spring abuts the end of the rotating rod 4, and the other end abuts the drive plate 342. The compression spring is used to drive the drive plate 342 to move outward from the rotating rod 4, that is, so that the end of the drive plate 342 facing the outside of the rotating rod 4 always remains in abutment with the drive plate 6. When the driving motor 3441 is started, it can drive the cam 3442 to rotate. When the distal end of the cam 3442 abuts against the driving disk 6, the driving plate 342 is driven to move toward the inside of the rotating roller 4. At this time, the wedge block 3421 squeezes the driving rod 341, driving the cleaning block 33 to move toward the end of the crushing knife 32, thereby achieving the purpose of cleaning the curved blade 322 and the vertical blade 321; and when the distal end of the cam 3442 gradually moves away from the driving disk 6, under the action of the compression spring, the driving plate 342 moves toward the outside of the rotating roller 4, causing the driving rod 341 and the cleaning block 33 to gradually reset.

[0049] Optionally, refer to Figure 3 , further comprising an air flow flushing system, the air flow flushing system comprising a high-pressure air nozzle 71 and an air source 72. The high-pressure air nozzle 71 is disposed on and communicated with the rotating rod 4. The air outlet direction of the high-pressure air nozzle 71 is toward the crushing blade 32. The output end of the air source 72 is communicated with one end of the rotating rod 4. The air source 72 may be an air pump, which is fixedly disposed on the housing 31. The end of the rotating rod 4 close to the drive motor 3441 is communicated with a rigid connecting pipe 42. The connecting pipe 42 is coaxially connected to the rotating rod 4. The end of the connecting pipe 42 away from the rotating rod 4 is rotatably connected to a connector 421. The connector 421 is fixedly connected to the vertical plate 311. The connector 421 is communicated with the output end of the air pump via an air pipe 73.

[0050] Each crushing blade 32 is provided with a high-pressure air nozzle 71 on both sides. The airflow direction of the high-pressure air nozzle 71 is 30 degrees away from the length direction of the vertical blade 321. 0 -45 0The high-pressure air nozzle 71 ejects a high-speed airflow, which directly impacts the sidewall of the curved blade 322 away from the vertical blade 321, cleaning the outside of the curved blade 322. The cleaning block 33 primarily cleans the inside of the curved blade 322, i.e., the sidewall closest to the vertical blade 321. The airflow flushing the pulverizing blades 32 removes fine residue and lowers the blade temperature, reducing wet straw adhesion. The airflow flushing system and the cleaning block 33 work together to effectively improve the cleaning effect of the pulverizing blades 32.

[0051] The implementation principle of the embodiment of the present application is as follows: the vehicle body 1 travels in the field, and the power component 35 drives the rotating rod 4 to rotate, and the rotating rod 4 drives the crushing knife 32 to rotate, thereby achieving the purpose of crushing the straw on the ground, and the burying mechanism 2 behind the vehicle body 1 rotates to dig the soil and bury the crushed straw on the ground under the soil; because the space in the gap between the vertical blade 321 and the curved blade 322 is limited, soil and straw are easily adhered to this gap. During the working process or after working for a period of time, the cleaning part is driven by the driving mechanism to move radially along the rotating rod 4, and the cleaning part moves in the direction away from the rotating rod 4, thereby achieving the purpose of cleaning the soil or straw adhered between the vertical blade 321 and the curved blade 322, preventing soil and straw from adhering to the crushing knife 32, improving the straw crushing effect, and there is no need to stop the machine and manually clean the crushing knife 32 regularly.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
