Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery accessories, and in particular to a cover shell and a soil covering mechanism with soil guiding and ridge body compacting functions. Background Art

[0002] In the process of planting crops in ridges, it is generally necessary to go through the operations of digging trenches, placing seedlings, and covering with soil. The applicant has newly developed a technology of placing the seedlings horizontally on the top of the ridge and then taking soil from the side of the ridge to cover the roots of the seedlings. This solution is not an existing technology. In this scheme, soil throwing and covering are the key to the whole process. The applicant's prior application CN114793496A discloses a soil throwing and ridge building mechanism and a layered ridge building device, which are used to apply fertilizer and pesticide to the ridge core during the ridge building process to avoid the trouble of subsequent fertilization and pesticide application. The soil throwing and ridge building mechanism in this patent includes a soil throwing knife group, front and rear baffles and an inclined plate. During the soil throwing process, the soil moves to the top of the ridge under the guidance of the inclined plate to cover the fertilizer on the top of the ridge. The soil throwing and ridge building mechanism cannot be directly used in the soil covering operation of the roots of the seedlings. There are mainly the following problems: (1) The soil thrown out is very scattered and the amount of soil is small. The roots of the seedlings on the top of the ridge cannot be covered in time. The scattered broken soil will disrupt the posture of the seedlings and easily cover the heads of the seedlings with soil. (2) A ridge body compaction mechanism must be set up later, and the overall length of the machine is long and not compact enough. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a cover and soil covering mechanism that can reasonably cover the seedlings on the top of the ridge with soil, and has high aggregation of the thrown soil and good soil covering quality, and has soil guiding and ridge compacting functions.

[0004] Technical solution: To achieve the above-mentioned purpose, the cover shell with soil guiding and ridge body compacting functions of the present invention has a transverse guide cover extending in the left and right directions, and one end of the transverse guide cover has a soil throwing wheel installation position; the cover shell also has an outer side plate and a rear side plate respectively located on the outer side and rear side of the soil throwing wheel installation position;

[0005] The other end of the transverse guide cover is provided with a baffle, that is, the baffle and the soil throwing wheel are respectively arranged at the two transverse ends of the transverse guide cover; and the rear half of the transverse guide cover is bent downward;

[0006] An L-shaped compacting plate is fixed to the rear side of the rear side plate.

[0007] The soil throwing wheel is equipped with a lateral guide cover, and the soil throwing knife is used to pick up soil from the ridge side and throw it upwards in a direction close to the ridge body during the rotation of the soil throwing wheel at the soil throwing wheel installation position. The soil thrown by the soil throwing wheel is gathered below by the transverse guide cover, and part of the soil moves laterally along the transverse guide cover. Since the rear half of the transverse guide cover is bent downward, the soil moving along the inner wall of the rear half is guided forward and gathered, which can gather the soil to improve the soil covering effect and prevent the soil from leaking to the rear side of the compaction plate. After the soil throwing knife of the soil throwing wheel leaves the lowest position, it rotates in a direction close to the rear side plate. In this way, when the soil throwing wheel rotates, part of the soil it brings up is accumulated between the rear side plate and the soil throwing wheel. In this way, when each soil throwing knife passes in front of the rear side plate, it can take part of the accumulated soil and throw it upwards, which can increase the soil taking angle of the soil throwing wheel, so that more soil is thrown obliquely upward, and the amount of soil thrown out can be increased.

[0008] The soil covering mechanism where the cover shell is located is used to cover the roots of the seedlings lying on the top of the ridge with soil. The seedlings are placed horizontally on the top of the ridge. During the soil covering operation, the middle and lower sides of the seedlings are located within the coverage range of the cover shell, so that the soil thrown out by the soil covering mechanism will not cover the heads of the seedlings.

[0009] Furthermore, the transverse guide cover includes two parts, a fixed part and a movable part, which are relatively rotatably installed. The fixed part is close to the installation position of the earth-throwing wheel and is fixed relative to the frame of the machine when in use. The baffle is fixed relative to the movable part. The rear halves of the fixed part and the movable part are both bent downward. With the above structure, the movable part can perform adaptive adjustment of the pitch angle. When the amount of soil thrown up by the earth-throwing wheel is small, the movable part remains stationary, and the soil moving along the transverse guide cover can be guided to a farther position as much as possible to fall. When the amount of soil thrown up by the earth-throwing wheel is large, a large amount of soil hits the movable part to lift the movable part. The movable part can consume the kinetic energy of the soil, causing part of the soil to fall midway, thereby achieving uniform soil covering in the area covered by the transverse guide cover on the top of the ridge, and preventing all the soil from sliding off the baffle, resulting in too much soil under the baffle and too little soil covering in other areas.

[0010] Furthermore, in this solution, the fixed part and the movable part are connected by a hinge.

[0011] Furthermore, the compacting plate includes a transverse extrusion plate and a side extrusion plate, the side extrusion plate is connected to the rear side plate; the front edge of the transverse extrusion plate is higher than the rear edge; in the front-to-back direction, the front edge of the side extrusion plate is further outward than the rear edge thereof. In this way, the front side of the compacting plate forms a bell mouth, which can better compact the loose soil on the ridge body, and the loose soil will not leak to the outside of the compacting plate. The compacting plate can act not only on the top of the ridge, but also on the side of the ridge.

[0012] Furthermore, an arc-shaped partition is provided between the throwing wheel and the rear side plate; the arc center of the partition coincides with the rotation center of the throwing wheel. With the above structure, when the throwing knife of the throwing wheel takes soil from the bottom of the ridge, it squeezes a part of the soil between the rear side plate and the partition at the same time. As the rear side plate moves forward, the rear side plate can push the soil forward. Thus, under the squeezing action of the front and rear sides, part of the soil moves upward along the gap between the rear side plate and the partition, and falls down from the upper end of the partition. The fallen soil can replenish the soil for the throwing knife due to its upper position, so that more soil can be thrown obliquely upward and move along the lateral guide cover, which can effectively ensure the amount of soil thrown.

[0013] The soil covering mechanism comprises the above-mentioned cover shell; the soil throwing wheel is installed at the soil throwing wheel installation position; and the wheel axle of the soil throwing wheel is arranged on the left and right sides.

[0014] Furthermore, the outer side of the outer plate has a transmission box connected to the earth-throwing wheel.

[0015] Beneficial effects: The cover and soil covering mechanism with soil guiding and ridge compaction functions of the present invention have the following beneficial effects:

[0016] (1) The structure of the lateral guide cover, the baffle plate and the layout of the rear side plate can increase the amount of soil thrown out by the soil throwing wheel and improve the concentration of the thrown soil, so as to timely cover the roots of the seedlings, improve the soil covering effect and timeliness, and prevent the soil from being too dispersed and unable to press the seedlings in time, resulting in the seedlings being hit and displaced by the broken soil.

[0017] (2) The movable part in the lateral guide cover can adaptively pitch and fall according to the amount of soil thrown, so that the soil can be spread more evenly on the top of the ridge and fully cover the roots of the seedlings.

[0018] (3) The fixed part, the outer plate, the rear side plate and the compacting plate are all fixed to each other, the structure is compact and reliable, and the production is convenient, which is conducive to the miniaturization of the machine where the soil covering mechanism is located. That is, the soil covering mechanism has its own ridge compacting and trimming unit, and there is no need to set up a ridge compacting and trimming mechanism separately, which can greatly reduce the machine volume.

[0019] (4) In the preferred embodiment, an arc-shaped baffle is provided to further increase the amount of soil thrown upward. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] like Figure 1-2 The cover shell shown in the figure has the functions of guiding soil and compacting ridges, and has a transverse guide cover 1 extending in the left-right direction, and one end of the transverse guide cover 1 has a soil-throwing wheel mounting position; the cover shell also has an outer plate 3 and a rear side plate 4 respectively located on the outer side and rear side of the soil-throwing wheel mounting position; the other end of the transverse guide cover 1 has a baffle 5, that is, the baffle 5 and the soil-throwing wheel 2 are arranged at the lateral ends of the transverse guide cover 1; and the rear half of the transverse guide cover 1 is bent downward; an L-shaped compaction plate 6 is fixed to the rear side of the rear side plate 4.

[0030] The above-mentioned cover is used for covering mechanism, such as Figure 3-4 As shown, the soil covering mechanism includes the above-mentioned cover shell; the soil throwing wheel 2 is installed at the soil throwing wheel installation position; the wheel axle of the soil throwing wheel 2 is arranged on the left and right. The outer side of the outer plate 3 has a transmission box 8 connected to the soil throwing wheel 2.

[0031] With the above structure, during the rotation of the throwing wheel 2, the throwing knife can take soil from the side of the ridge and throw the soil upward and toward the ridge body. The soil thrown by the throwing wheel 2 is gathered below by the lateral guide cover 1. Figure 5As shown, part of the soil moves laterally along the lateral guide cover 1. Since the rear half of the lateral guide cover 1 is bent downward, the soil moving along the inner wall of the rear half is guided forward and gathered, which can gather the soil to improve the soil covering effect and prevent the soil from leaking to the rear side of the compaction plate 6; after the soil throwing knife of the soil throwing wheel 2 leaves the lowest position, it rotates toward the direction close to the rear side plate 4. In this way, when the soil throwing wheel 2 rotates, part of the soil it brings up is accumulated between the rear side plate 4 and the soil throwing wheel 2. In this way, when each soil throwing knife passes in front of the rear side plate 4, it can take a part of the accumulated soil and throw it up, which can increase the soil taking angle of the soil throwing wheel 2, so that more soil is thrown obliquely upward, and the amount of soil thrown out can be increased.

[0032] The soil covering mechanism where the cover shell is located is used to cover the roots of the seedlings lying on the top of the ridge with soil. The seedlings are placed horizontally on the top of the ridge. During the soil covering operation, the middle and lower sides of the seedlings are located within the coverage range of the cover shell, so that the soil thrown out by the soil covering mechanism will not cover the heads of the seedlings.

[0033] In one embodiment, if Figure 2 As shown, the transverse guide cover 1 includes a fixed part 11 and a movable part 12, and the fixed part 11 and the movable part 12 are connected by a hinge 13. The fixed part 11 is close to the installation position of the soil throwing wheel, and is fixed relative to the frame of the machine when in use, and the baffle 5 is fixed relative to the movable part 12. The rear half of the fixed part 11 and the movable part 12 are bent downward. With the above structure, the movable part 12 can perform adaptive adjustment of the pitch angle. When the amount of soil thrown up by the soil throwing wheel 2 is small, the movable part 12 remains stationary, and the soil moving along the transverse guide cover 1 can be guided to a farther position as far as possible to fall. When the amount of soil thrown up by the soil throwing wheel 2 is large, a large amount of soil hits the movable part 12 to lift the movable part 12, and the movable part 12 can consume the kinetic energy of the soil, so that part of the soil falls midway, so as to achieve uniform soil covering in the area covered by the transverse guide cover 1 on the top of the ridge, and prevent all the soil from sliding from the baffle 5, resulting in too much soil under the baffle 5 and too little soil covering in other areas.

[0034] In another embodiment, if Figure 7As shown, the above-mentioned transverse guide cover 1 is integrally formed, and has a plurality of transversely extending hollow holes 1a on the transverse guide cover 1. In addition, the end of the transverse guide cover 1 also has an extension portion 1b that continues to extend to the outside of the baffle 5; a cover plate 9 is rotatably installed on the top of the transverse guide cover 1. When the amount of soil thrown up is small, the cover plate 9 is in a closed state, blocking the hollow holes 1a, so that as much soil as possible can fall before the baffle 5. When the amount of soil thrown up is large, the cover plate 9 is pushed open by the soil, and part of the soil can pass through the hollow holes 1a to reach the upper side of the transverse guide cover 1 and detach from the transverse guide cover 1 from the end of the extension portion 1b. This part of the soil will not cover the head of the sweet potato seedling. The above structure can realize the adaptive adjustment of the amount of soil covering, so that when the amount of soil thrown is large, part of the soil can bypass the top of the transverse guide cover 1 and reach the other side of the sweet potato seedling.

[0035] Preferably, the compacting plate 6 comprises a transverse extrusion plate 61 and a side extrusion plate 62, and the side extrusion plate 62 is connected to the rear side plate 4; Figure 4 As shown, the front edge of the transverse extrusion plate 61 is higher than the rear edge; in the front-to-back direction, the front edge of the side extrusion plate 62 is further outward than its rear edge. In this way, the front side of the compaction plate 6 forms a bell mouth, which can better compact the loose soil on the ridge body, and the loose soil will not leak to the outside of the compaction plate 6. The compaction plate 6 can act not only on the top of the ridge, but also on the side of the ridge. The above-mentioned fixed part 11, the outer plate 3, the rear side plate 4 and the compaction plate 6 are all fixed to each other, with a compact and reliable structure, and easy production, which is conducive to the miniaturization of the machine where the covering mechanism is located.

[0036] Preferably, if Figure 6 As shown, an arc-shaped partition 7 is provided between the earth-throwing wheel 2 and the rear side plate 4; the arc center of the partition 7 coincides with the rotation center of the earth-throwing wheel 2. With the above structure, when the earth-throwing knife of the earth-throwing wheel 2 takes soil from the bottom of the ridge, it squeezes a part of the soil between the rear side plate 4 and the partition 7 at the same time. As the rear side plate 4 moves forward, the rear side plate 4 can push the soil forward. In this way, under the squeezing action of the front and rear sides, part of the soil moves upward along the gap between the rear side plate 4 and the partition 7, and falls down from the upper end of the partition 7. The fallen soil can replenish the soil for the earth-throwing knife due to its upper position, so that more soil can be thrown obliquely upward and move along the transverse guide cover 1, which can effectively ensure the amount of earth thrown.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
