Description

Technical Field

[0001] The invention relates to the field of deep plowing and returning-to-field devices in rice-growing areas, and in particular to a deep plowing and returning-to-field device for peas in rice-growing areas. Background Art

[0002] Deep plowing is an agricultural production technology that involves burying rice straw in the rice field as an organic fertilizer to improve soil quality and promote crop growth. The implementation of this technology in rice-growing areas is of great significance for improving soil health, increasing crop yields and reducing environmental pollution.

[0003] Deep plowing of the peas is mainly done when the peas are in full bloom, so that their fresh grass can be buried in the soil of the farmland. This can enhance soil fertility and microbial activity, increase rice yields, and achieve increased production. In addition, deep plowing of the peas for many consecutive years can significantly increase the organic matter content in the soil, which is conducive to the formation of soil aggregate structure, improve the soil's buffering capacity, and prevent soil acidification, thereby achieving the effect of soil improvement.

[0004] In the prior art, deep plowing and returning of the eel pea to the field is mainly carried out by burying the rhizomes of the eel pea in the soil for decomposition using a rotary tiller or a tiller. The current devices are not effective enough in turning over and decomposing the rhizomes of the eel pea, and during the turning over process, the plowshares of the tiller are usually multiple and rise or fall synchronously, resulting in the front plowshare working in the normal working area while the rear plowshare is working outside the working area, and it is impossible to turn over the soil in the normal working area with multiple plowshares.

The device is arranged behind an agricultural tractor, and the movements of various parts of the device are realized by dragging and operating the tractor. The tractor is connected to a bracket. When not working, a rotary tillage mechanism and a tillage lifting mechanism are in a raised state to prevent the distance between the device and the ground from being too small during the dragging process, resulting in a collision with the plowshare and the rotary tillage blade. After entering the working state, the rotary tillage mechanism and the tillage mechanism begin to descend, so that the machine reaches a suitable height for working. When the plowshare enters the working area, the hydraulic cylinder controls the plowshare to move, so that the plowshare enters the working area. The height is adjusted when turning the soil, and the hydraulic cylinder does not control the movement of the plowshare that has not entered the working area until all the plowshares move in sequence when entering and exiting the working area, to prevent all the plowshares from descending at the same time and damaging the ground outside the working area. After harvesting, the rhizomes of the arrow pea will remain on the land. At this time, the rotary tillage mechanism will crush the rhizomes, and finally the soil will be turned over and returned to the field through the soil turning mechanism. When it reaches the end point, the machine rises, and the flipping mechanism starts to flip and use the upper plowshare to return to turn the soil, so that the turning of the soil is in the same direction. The entire mechanism shortens the working time and there is no need to change the machine walking process multiple times, thereby maximizing the effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The plowshare hydraulic cylinder 409 operates in sequence. When the plowshare 408 enters the working area, the plowshare hydraulic cylinder 409 operates to adjust the plowshare 408 to a suitable height. After that, when the plowshare 408 does not enter the working area, the plowshare hydraulic cylinder 409 does not operate. When the work is completed, the plowshare hydraulic cylinder 409 is lifted in sequence in the same way.

[0024] Second embodiment Please refer to Figure 2 , Figure 3 , Figure 5 , Fig.11 and Fig.12 Based on the deep turning and returning device for arrow peas in rice fields provided in the first embodiment of the present application, the second embodiment of the present application proposes another deep turning and returning device for arrow peas in rice fields. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0025] Specifically, the second embodiment of the present application provides a rice field arrow pea deep plowing and returning device. The difference is that a plowing lifting mechanism 6 is fixedly installed on one side of the plowing mounting frame 401, and a flipping mechanism 7 is fixedly connected to the left surface of the plowing mounting frame 401. The plowing lifting mechanism 6 includes: a walking fixed frame 603 and a plowing walking wheel 604. The flipping mechanism 7 includes: a flipping hydraulic fixing plate 711, a walking flipping gear 708 and a flipping gear mounting plate 705. The walking fixed frame 603 is fixedly installed on the front surface of the plowing mounting frame 401, and a rotating shaft 602 is rotatably installed on the front surface of the plowing fixed frame 603. A walking wheel mounting frame 601 is fixedly installed on one end of the rotating shaft 602. The plowing walking wheel 604 is fixedly installed on the bottom end of the walking wheel mounting frame 601 near the bottom surface, and the flipping hydraulic fixing plate 711 is fixedly installed on the front side of the plowing mounting frame 401 near the right end. The flip hydraulic cylinder 710 has a slide tooth plate 709 fixedly installed on the left side of the flip hydraulic cylinder 710, and the slide tooth plate 709 is equipped with a flip slide 707. The upper surface of the flip slide 707 is fixedly connected to the upper surface of the inner part of the walking fixed frame 603. The slide tooth plate 709 is meshed with the walking flip gear 708. The flip gear 708 is rotatably installed inside the walking fixed frame 603 and fixedly installed on the rotating shaft 602. The left end surface of the slide tooth plate 709 is fixed A linkage rod 706 is fixedly installed, and a shift fork 704 is fixedly installed on the left end face of the linkage rod 706. The flipping gear mounting plate 705 is fixedly installed on the left end face of the turning mounting frame 401. A spline shaft 702 is fixedly installed on the left surface of the flipping gear mounting plate 705. A flipping gear 703 is slidably installed on the spline shaft 702 close to the left end surface. A transmission gear 701 is meshed on one side of the flipping gear 703, and a flipping motor 28 is fixedly connected to the left side of the transmission gear 701.When the flip hydraulic cylinder 710 pushes the slide slot tooth plate 709, it drives the walking flip gear 708 and then drives the walking wheel mounting frame 601 to rotate half a circle. At the same time, during the pushing process, it drives the shift fork 704 to push the flip gear 703 to engage with the transmission gear 701 to drive the turning mechanism 4 to rotate half a circle. The gear teeth 7081 of the walking flip gear 708 can move in one direction. When the slide slot tooth plate 709 retreats, the gear teeth 7081 rotates. When the slide slot tooth plate 709 returns to its original position, the spring 7082 The gear tooth 7081 is bounced back, and each tooth portion of the walking flipping gear 708 is installed with a spring 7082. When the sliding groove tooth plate 709 is retreated, the spring 7082 of the walking flipping gear 708 is squeezed. Therefore, when the sliding groove tooth plate 709 is retreated, it no longer drives the walking flipping gear 708 to rotate. At this time, the walking wheel mounting frame 601 does not flip, and a sliding groove is provided on the surface of the flipping gear 703, so that the fork 704 is installed in the sliding groove to ensure that it will not affect the rotation of the walking flipping gear 708 when it is shifted.

[0026] The length of the sliding groove tooth plate 709 matches the walking and flipping gear 708, so that when the flipping hydraulic cylinder 710 pushes the sliding groove tooth plate 709 to pass through the walking and flipping gear 708, it just makes the walking wheel mounting frame 601 drive the turning walking wheel 604 to flip half a circle, and when the flipping hydraulic cylinder 710 pushes, it can also drive the fork 704 to push the flipping gear 703 to engage with the transmission gear 701, so as to realize the turning mechanism 4 to flip half a circle.

[0027] The working principle of the deep turning and returning device for peas in rice fields provided by the present invention is as follows: when turning back and forth, the bracket 24 will rise, so that the device is a certain distance away from the ground, ensuring that the turning mechanism 4 can be turned over smoothly. When turning over, the turning lifting mechanism 6 will retract, and at the same time, the turning hydraulic cylinder 710 will extend, and the slide tooth plate 709 will mesh with the walking turning gear 708, driving the turning lifting mechanism 6 to turn over half a circle. When the turning hydraulic cylinder 710 is extended, the shift fork 704 drives the turning gear 703 to mesh with the transmission gear 701, and the turning motor 28 To drive the transmission gear 701 to drive the tillage mechanism 4 to perform a half-circle flip. After reaching the half-circle position, the tillage lifting mechanism 6 extends the auxiliary device to perform walking tillage, and the flipping hydraulic cylinder 710 retracts, driving the shift fork 704 and the flipping gear 703 to retreat. While retreating, the slide groove tooth plate 709 presses against the teeth of the walking flipping gear 708 so that its movement does not hinder the movement of the slide groove tooth plate 709. The spring 7082 of the teeth 7081 of the flipping gear 708 is compressed. When the slide groove tooth plate 709 returns to its position, the teeth 7081 of the flipping gear 708 are restored by the spring 7082.

[0028] Compared with the related art, the deep plowing and returning device for peas in rice fields provided by the present invention has the following beneficial effects: under the action of the turning mechanism 7 and the tillage lifting mechanism 6, the mechanism reduces a certain pressure on the tractor when turning the soil, and further ensures the appropriate height of the plowshare 408 when turning the soil through auxiliary walking, and no longer needs to rely on the tractor for specific height adjustment control. When turning over, the tillage lifting mechanism 6 can be turned over together and the turning hydraulic cylinder 710 can control the tillage lifting mechanism 6 and the tillage mechanism 4 in a linkage manner, and there is no need for the turning mechanism 7 to be operated and controlled to rotate separately, which simplifies the operation during turning over.

[0029] Third embodiment Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 ,picture, Fig.10 and Fig.11 Based on the device for deep plowing and returning peas to the field in a rice field provided in the first embodiment of the present application, the third embodiment of the present application proposes another device for deep plowing and returning peas to the field in a rice field. The third embodiment is only a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the independent implementation of the first embodiment.

[0030] Specifically, the third embodiment of the present application provides a rice field arrow pea deep turning and returning device. The difference is that a pair of cross-frame plates 19 are fixedly installed near the upper surface on both sides of the rotary tillage blade frame 303, and a fixed strap 14 is fixedly installed on the surface of the cross-frame plate 19.

[0032] During flipping, the harvesting mechanism 1, the crushing mechanism 2 and the blower 9 stop working to ensure that the crushed arrow peas will not be blown away when the blow pipe 22 and the adapter blow pipe 17 are separated during flipping. A symmetrically arranged adapter blow pipe 17 is installed on the upper and lower parts of the turning mounting frame 401 to ensure that the crushed arrow peas can be blown onto the surface of the plowshare 408 every time the blow pipe 22 and the adapter blow pipe 17 are flipped, and the upper and lower harvesting knives are staggered to ensure that the moving distance is the distance of a knife tooth, which is conducive to harvesting.

[0033] The working principle of the deep turning and returning device for peas in rice fields provided by the present invention is as follows: when turning the soil, the crushing hydraulic cylinder 503 drives the hydraulic mounting frame 504 and the walking wheel 507 to descend, and at the same time, the turning lifting mechanism 6 also starts to descend so that the whole device reaches a suitable height. At this time, the plowshare hydraulic cylinder 409 sequentially adjusts the height of the plowshare 408 to reach the required turning depth, and at the same time, the crushing motor 20, the blower 9 and the turning motor 28 are started, and the crushing motor 20 drives the crushing gear 1 21 to mesh with the crushing gear 2 23 to rotate, so that the crushing knife 203 and the crushing knife 204 and the crushing knife 206 are rotated. The winding shaft 201 is crushed and rotated in the crushing mechanism 2. While the blower 9 is blowing, it also drives the cutting transmission shaft 26 and the universal joint 27 to rotate, and further drives the harvesting eccentric shaft 105 to rotate. Under the rotation of the harvesting eccentric shaft 105, through the joint action of the harvesting connecting block 104 and the harvesting knife pushing rod 103, the upper harvesting knife 101 reciprocates to harvest the arrow peas. After harvesting, the arrow peas are transferred to the crushing mechanism 2 for crushing through the transfer roller 107, and then the crushed arrow peas are blown onto the ground through the blow pipe 22 by the blower 9.

[0034] Compared with the related art, the deep turning and returning device for peas in rice fields provided by the present invention has the following beneficial effects: the tractor is connected to the bracket 24, and the crushing lifting mechanism 5 and the tilling lifting mechanism 6 are in a raised state when not working, so as to prevent the distance between the device and the ground from being too small during the dragging process, resulting in collision with the plowshare 408, the rotary tiller 301 and the harvesting knife. After entering the working state, the hydraulic cylinder in the crushing mechanism 2 and the tilling mechanism 4 begin to descend so that the harvesting mechanism 1 reaches a suitable harvesting height for harvesting, and the lifting and lowering of the tilling mechanism 4 controls the turning of the tilling plowshare 408. At the same time, the combined action of the crushing lifting mechanism 5 and the turning over lifting mechanism 6 enables the rotary tillage mechanism 3 in the middle position to be appropriately adjusted in height. During the harvesting process, the harvesting mechanism 1 harvests the arrow peas, and transfers the harvested arrow peas to the crushing mechanism 2 through the transfer roller 107. After crushing, the arrow peas will enter the crushing collection box 25 and be blown onto the plowshare 408 through the blower 9 through the blow pipe 22, ensuring that they can be turned into the soil when turning over the soil and also retain some decomposition on the soil surface to increase fertility and maximize the turning over effect.
