Four-row vegetable transplanter rotary tiller and coverer

Abstract

The application relates to a four-row vegetable transplanting rotary tillage and soil covering device. The device can adapt to four-row vegetable film covering, transplanting and soil covering operation, and makes up the limitation of traditional devices which only support two-row operation. The device divides the soil covering cover into a first soil covering cavity and a second soil covering cavity arranged in front and back through a partition plate. The first soil covering cavity on the front side is designed to have a smaller cross section area than the second soil covering cavity on the rear side, so as to compensate for the characteristics of the soil amount decreasing during the rotary tillage cutter rotating, and make the soil amounts of the two conveying plates basically balanced. The first conveying plate with a longer length and the second conveying plate with a shorter length are matched, so that the soil can be guided to the inner and outer sides of the corresponding rows of the film, the soil covering thicknesses of the four rows are uniform, the film fixing effect is stable, the wind prevention and soil conservation effects of the film are effectively exerted, and the survival rate of the crop seedlings is improved.

Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, and in particular to a rotary tillage and soil covering device for a four-row vegetable transplanter. Background Technology

[0002] In crop mulching and transplanting operations, the rotary tillage and soil covering device is a key functional component of the transplanter. It is mainly used to rotary till and break up the soil on both sides of the ridge, and then guide the tilled soil to cover the surface of the mulch film, providing stable working conditions for subsequent seedling planting. Mulching effectively resists wind and sand damage to the mulch film, preventing moisture loss from the soil beneath it, and plays a vital role in maintaining soil moisture and improving crop seedling survival rates.

[0003] Existing rotary tillage and soil covering devices for transplanters are mostly adapted to two-row crop planting patterns. For example, Chinese invention patent CN223437342U, entitled "A Rotary Tillage and Soil Covering Device for Transplanters," can only complete the mulch covering operation for two rows of crops and cannot meet the mulch covering requirements for four-row crop transplanting. Even if existing technologies are improved to achieve soil covering for four rows of crops, how to achieve uniform soil coverage on the mulch film under four-row operation conditions, ensuring consistent soil covering thickness and stable mulch film fixation, has become an urgent technical problem to be solved in this field. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to evenly cover the soil on the corresponding planting rows of the mulch film when covering four rows of crops with soil.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: This invention is a rotary tillage and soil covering device for a four-row vegetable transplanter, comprising: a frame, rotary tillage covers on both sides of the frame, and rotatable rotary tillage blades inside the rotary tillage covers; The inner wall of the rotary tiller has a soil outlet, and a soil dividing hood extends from the soil outlet toward another rotary tiller. The soil dividing hood is equipped with a partition, which divides the soil dividing hood into a first soil covering cavity and a second soil covering cavity with openings facing the other rotary tiller. The second soil covering cavity is located behind the first soil covering cavity in the rotation direction of the rotary tiller blade, and the cross-sectional area of ​​the first soil covering cavity is smaller than the cross-sectional area of ​​the second soil covering cavity. The first soil covering cavity extends obliquely downward toward the other rotary tillage hood with a first conveying plate, and the second soil covering cavity extends obliquely downward toward the other rotary tillage hood with a second conveying plate, the length of the first conveying plate being greater than the length of the second conveying plate.

[0006] Furthermore, the first conveying plate and the second conveying plate are provided with flanges on both sides in the width direction, and a locking member is provided on the flange near the soil outlet. The soil separating cover and the partition plate are provided with an adjustment groove. The locking member is locked with the adjustment groove to adjust the length of the first conveying plate or the second conveying plate extending out of the soil separating cover.

[0007] Furthermore, the top surface of the rotary tillage hood is an inclined surface, and the tilled soil can impact the inclined surface and be guided to the first or second covering cavity.

[0008] Furthermore, the bottom of the rotary tillage cover is equipped with a flexible mudguard.

[0009] Furthermore, the rotary tiller cover is connected to the frame via a power box, the top of the power box is equipped with an input shaft, and a synchronous belt is installed inside the power box. The power input shaft of the rotary tiller blade is connected to the synchronous belt.

[0010] The beneficial effects of this invention are: This device is suitable for mulching and soil covering operations for transplanting four rows of vegetables, overcoming the limitation of traditional rotary tillage and soil covering devices that only support two rows. A partition divides the soil covering cover into a first and a second soil covering chamber arranged front and rear. The design of the first soil covering chamber having a smaller cross-sectional area than the second chamber compensates for the decreasing soil volume carried by the rotary tiller blades in the rotation direction, ensuring a relatively even total amount of soil entering the two conveyor plates. Simultaneously, the first conveyor plate's longer length than the second ensures that the soil falls onto the corresponding rows on the inner and outer sides of the mulch film, ultimately achieving a uniform soil covering thickness across all four rows, stable mulch film fixation, effectively protecting the mulch film from wind and retaining moisture, and improving crop seedling survival rates.

Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0014] See Figure 1-5 This embodiment is a rotary tillage and soil covering device for a four-row vegetable transplanter, including: a frame 1, with rotary tillage covers 2 respectively set on the left and right sides of the frame 1, and a semi-circular cavity formed inside the rotary tillage cover 2 for mounting the rotating rotary tillage blades 3; The inner wall of the rotary tillage cover 2 is provided with a soil outlet 21, that is, the right side of the left rotary tillage cover 2 is provided with a soil outlet 21, and the left side of the right rotary tillage cover 2 is provided with a soil outlet 21. The soil outlet 21 is preferably a fan-shaped structure. A soil dividing cover 4 extends obliquely from the soil outlet 21 toward the other rotary tillage cover 2, and the cross section of the soil dividing cover 4 is preferably a fan-shaped cross section. The soil separating cover 4 is provided with a partition 5, which is a plate-shaped structure, and the installation direction of the partition 5 is the same as the extension direction of the soil separating cover 4. The partition 5 divides the soil-separating cover 4 into a first soil-covering cavity 41 and a second soil-covering cavity 42 with openings facing the other rotary tillage cover 2. The second soil-covering cavity 42 is located behind the first soil-covering cavity 41 in the rotation direction of the rotary tillage blade 3. The cross-sectional area of ​​the first soil-covering cavity 41 is smaller than the cross-sectional area of ​​the second soil-covering cavity 42. In other words, the soil outlet is divided into two parts by the partition 5, with the area of ​​the front soil outlet 21 being smaller than that of the rear soil outlet 21. The first soil covering cavity 41 extends obliquely downward toward the other rotary tillage hood 2 with a first conveying plate 61, and the second soil covering cavity 42 extends obliquely downward toward the other rotary tillage hood 2 with a second conveying plate 62. The length of the first conveying plate 61 is greater than the length of the second conveying plate 62, and the width of the first conveying plate 61 is less than the width of the second conveying plate 62. In this embodiment, in the rotation direction of the rotary tiller 3, the first covering cavity 41 is located in front of the second covering cavity 42, and the cross-section of the first covering cavity 41 is smaller than the cross-section of the second covering cavity 42. The rotary tiller blade 3 rotates clockwise, and the soil broken by the rotary tiller blade is carried into the rotary tiller hood 2 and guided out from the soil outlet 21 onto the first conveyor plate 61 or the second conveyor plate 62. As the rotary tiller blade 3 rotates, the amount of soil guided out gradually decreases. In order to balance the amount of soil entering the first conveyor plate 61 and the second conveyor plate 62 to be approximately the same, the cross-sectional area of ​​the first soil covering cavity 41 is set to be smaller than the cross-sectional area of ​​the second soil covering cavity 42. The length of the first conveyor plate 61 is set to be greater than the length of the second conveyor plate 62, so that the soil covering the mulch film after passing through the second conveyor plate 62 is located on the outside of the soil covering the mulch film after passing through the first conveyor plate 61. With the above settings, when covering four rows of crops with soil, the soil can be evenly spread over the planting rows of the mulch film.

[0015] If the cross-sectional area of ​​the first soil covering cavity 41 is equal to the cross-sectional area of ​​the second soil covering cavity 42, that is, the partition 5 is set in the middle of the soil outlet 21, the amount of soil entering the first conveying plate 61 will be greater than the amount of soil on the second conveying plate 62, and ultimately the amount of soil covering the outer mulch film will be less than the amount of soil covering the inner mulch film, making it impossible to evenly cover the soil on the planting rows of the mulch film.

[0016] See Figure 5 In some possible embodiments, the first conveying plate 61 and the second conveying plate 62 are provided with flanges 71 on both sides in the width direction. The flanges 71 are provided with locking members 72 near the soil outlet 21. The soil dividing cover 4 and the partition plate 5 are provided with adjusting grooves 73. The locking members 72 are locked with the adjusting grooves 73 to adjust the length of the first conveying plate 61 or the second conveying plate 62 extending out of the soil dividing cover 4. In this embodiment, when facing soil covering with different row spacings, the extension and retraction of the first conveying plate 61 and the second conveying plate 62 relative to the soil dividing cover 4 are adjusted. That is, the corresponding conveying plate slides in the adjusting groove 73 with the locking member 72. After the conveying plate is moved to a suitable position, the corresponding conveying plate is locked with the partition plate 5 and the soil dividing cover 4.

[0017] See Figure 6 In some possible embodiments, the top surface of the rotary tillage cover 2 is an inclined surface 22, and the soil after rotary tillage can impact the inclined surface 22 and be guided from the soil outlet 21 to the first soil covering cavity 41 or the second soil covering cavity 42. In this embodiment, by setting the inclined surface 22, more soil can be guided from the outlet 21 to the first conveying plate 61 or the second conveying plate 62, where the arrow indicates that the soil hits the inclined surface 22 and is guided out from the outlet 21.

[0018] See Figure 1 In some possible embodiments, the bottom of the rotary tillage cover 2 is provided with a flexible mudguard 8; In this embodiment, the mudguard 8 can contact the ground, and by setting the mudguard 8, the soil after rotary tillage is prevented from being thrown out of the rotary tillage cover 2.

[0019] See Figure 1 In some possible embodiments, the rotary tillage cover 2 is connected to the frame 1 via a power box 9. The top of the power box 9 is provided with an input shaft 91, and a synchronous belt 92 is provided inside the power box 9. The power input shaft of the rotary tillage blade 3 is connected to the synchronous belt 92. In this embodiment, the input shaft 91 rotates, which drives the rotary tiller 3 to rotate in one direction via the synchronous belt 92, thereby achieving the effect of rotary tilling of the soil.

[0020] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
