Description

Technical Field

[0001] This invention belongs to the field of straw return equipment, specifically relating to a field straw vertical burying machine. Background Technology

[0002] Currently, straw return to the field is done by crushing the straw, rotary tilling, and burying it in the field. Rotary tilling can only mix the soil and straw at a shallow level, and it also damages the soil moisture. If this is done in saline-alkali land, soil moisture is even more precious. The straw burial method involves digging strip-shaped burial trenches in the field and spreading the straw in the trenches. Strip burial can bury the straw to a certain depth, but it cannot be evenly distributed in the ground. Furthermore, the decomposition in the soil is uneven, and the complete decomposition period of a large amount of straw is also long. Summary of the Invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a field straw vertical burial machine that can uniformly drill holes at designated locations in the field, and put the straw into the holes after it is segmented, thereby achieving uniform straw distribution. Since the straw is buried without clumping, the decomposition speed is fast, and there is no need to plow the soil over a large area, so it has little impact on soil moisture.

[0004] The specific technical solution adopted in this invention is as follows:

[0005] A field straw vertical burial machine includes a frame and a drilling device and a discharge device mounted on the frame. The drilling device includes a spiral drill rod and a funnel-shaped guide plate. The discharge device includes a discharge hopper and a pushing mechanism located below the discharge hopper. The discharge hopper contains segments of straw. A discharge window penetrating both sides of the discharge hopper is located below the discharge hopper. The pushing mechanism includes a pushing rod that reciprocates into the discharge window to push the straw in the discharge hopper into the guide plate.

[0006] The drilling device also includes a lifting bracket, which includes a vertical guide rail and a fixed crossbeam. A drive motor is installed on the fixed crossbeam, and the power output end of the drive motor is fixedly connected to the spiral drill rod. The vertical guide rail is vertically installed on the frame, and the fixed crossbeam is slidably connected to the vertical guide rail. A lifting telescopic cylinder is installed between the frame and the fixed crossbeam.

[0007] The discharge hopper includes a hopper section and a discharge section. The hopper section has a funnel-shaped structure, and the discharge section has a rectangular box-shaped structure. The inner cavities of the hopper section and the discharge section are connected. The discharge window is located at the bottom of the discharge section, and the output side of the discharge window is provided with a material drop chute that connects to the guide plate.

[0008] The pushing mechanism also includes a pushing beam, which has the freedom to move back and forth on the frame via a pushing slide rail. The pushing rod is mounted on the pushing beam, and the moving trajectory of the pushing rod passes through the discharge window. A pushing telescopic cylinder is provided between the pushing beam and the frame.

[0009] The spiral blades of the spiral drill rod are provided with a retaining flange on the outside, and the retaining flange, the spiral blades of the spiral drill rod, and the core rod form a groove-shaped soil holding groove.

[0010] The discharge section of the discharge hopper is provided with a through groove on its side wall, and a rotating feeding wheel is also provided on the side wall of the discharge section. The feeding wheel is provided with feeding blades, and the feeding blades extend into the inner cavity of the discharge section through the through groove.

[0011] The beneficial effects of this invention are:

[0012] This invention utilizes a drilling device to drill holes in the field using a spiral drill rod. Then, a set-out discharge device pushes out bundles of straw cut into sections, which fall into a guide plate. Guided by the funnel-shaped guide plate, the straw slides into the holes drilled in the previous step, achieving a uniform distribution of the straw. Because the straw does not clump together when buried, it decomposes quickly, and there is no need for large-scale tilling of the soil, thus preserving soil moisture. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] Specific implementation examples Figure 1 and Figure 2 As shown, the present invention is a field straw vertical burial machine, including a frame 1 and a drilling device and a discharge device mounted on the frame 1. The drilling device includes a spiral drill rod 2 and a funnel-shaped guide plate 3. The discharge device includes a discharge hopper 4 and a pushing mechanism disposed below the discharge hopper 4. The discharge hopper 4 contains segmented straw. A discharge window 5 penetrating both sides of the discharge hopper 4 is provided below the discharge hopper 4. The pushing mechanism includes a pushing rod 6, which reciprocates into the discharge window 5 to push the straw in the discharge hopper 4 into the guide plate 3.

[0025] The frame 1 of this invention is towed by a traction machine. The frame 1 is equipped with wheels and is towed by the traction machine to provide driving force. The spiral drill rod 2 of this invention drills holes in the field. The straw, cut into sections, is then pushed out in bundles by the discharge device and falls into the guide plate 3. With the help of the funnel-shaped guide plate 3, the straw slides into the holes drilled in the previous step, achieving a uniform distribution of straw. Since the straw does not clump together when buried, it decomposes quickly and there is no need for large-scale soil plowing, thus protecting soil moisture.

[0026] Furthermore, such as Figure 3 As shown, the drilling device also includes a lifting bracket, which includes a vertical guide rail 7 and a fixed crossbeam 8. A drive motor 9 is installed on the fixed crossbeam 8, and the power output end of the drive motor 9 is fixedly connected to the spiral drill rod 2. The vertical guide rail 7 is vertically installed on the frame 1, and the fixed crossbeam 8 is slidably connected to the vertical guide rail 7. A lifting telescopic cylinder 10 is installed between the frame 1 and the fixed crossbeam 8.

[0027] The fixed crossbeam 8 moves up and down along the vertical guide rail 7 by means of the telescopic drive of the lifting telescopic cylinder 10. The drive motor 9 is a hydraulic motor connected to the hydraulic system of the traction machine. The rotation of the drive motor 9 drives the spiral drill rod 2 to drill holes.

[0028] The spiral drill rod 2 is arranged in multiple sets at equal intervals on the fixed crossbeam 8, which can drill multiple holes at the same time, thereby improving the efficiency of drilling and vertical burial.

[0029] This invention utilizes straw from grain crops such as corn, sorghum, wheat, rice, and millet. By cutting the straw to the length that the discharge hopper 4 can accommodate, the crushing process is eliminated, reducing energy consumption and equipment investment. Through vertical burial with holes, the gaps between the straws and their loose internal structure ensure that vertical water transfer in the soil is not affected. Furthermore, the sufficient water transfer improves the straw decomposition speed. The hole depth is 40-50cm, and the straw depth to the ground surface is greater than 18cm, meaning the straw cutting length is 22-32cm. The burial of the loose straw forms an underground water-retaining structure, improving the water use efficiency of the field.

[0030] When applied in the improvement of saline-alkali land, the straw's water retention and infiltration effects provide a slow and continuous leaching effect on the deep soil, which helps to block the salt return process and improve the treatment effect of saline-alkali land.

[0031] Furthermore, such as Figure 2 and Figure 4 As shown, the discharge hopper 4 includes a hopper section 11 and a discharge section 12. The hopper section 11 has a funnel-shaped structure, and the discharge section 12 has a rectangular box-shaped structure. The inner cavities of the hopper section 11 and the discharge section 12 are connected. The discharge window 5 is located at the bottom of the discharge section 12, and the output side of the discharge window 5 is provided with a material drop groove 13 that connects to the guide plate 3.

[0032] The cut straw is put into the hopper section 11 of the discharge hopper 4. The direction of the straw is along the moving direction of the push rod 6. Under the action of gravity, the straw slides from the funnel-shaped hopper section 11 into the discharge section 12. Since the discharge section 12 is box-shaped, the straw is piled up in layers. The straw at the bottom is exposed at the discharge window 5. With the push of the push rod 6, the straw is pushed out.

[0033] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the pushing mechanism also includes a pushing beam 14, which has the freedom to reciprocate on the frame 1 via a pushing slide rail 15. The pushing rod 6 is mounted on the pushing beam 14, and the moving trajectory of the pushing rod 6 passes through the discharge window 5. A pushing telescopic cylinder 16 is provided between the pushing beam 14 and the frame 1.

[0034] With the extension and retraction of the pusher cylinder 16, the pusher rod 6 can extend into the discharge window 5 and push out the straw filled in the discharge window 5 to form a bundle of straw. This bundle of straw slides down the discharge chute 13 to the guide plate 3 and then falls into the hole in the ground.

[0035] Furthermore, such as Figure 5 As shown, a retaining flange 17 is provided on the outer side of the spiral blade of the spiral drill rod 2, and the retaining flange 17 and the spiral blade and core rod of the spiral drill rod 2 form a groove-shaped soil holding groove.

[0036] When the auger rod 2 drills into the soil and is pulled out, the set baffle 17 forms a barrier to the soil. In addition, the field soil has a certain moisture content, and the soil is moist and clumps together. After the auger rod 2 is pulled out, the soil is clamped in the soil holding groove and is pulled out together with the auger rod 2.

[0037] Furthermore, a through groove 18 is provided on the side wall of the discharge section 12 of the discharge hopper 4, and a rotating feeding wheel 19 is also provided on the side wall of the discharge section 12. A feeding blade 20 is provided on the feeding wheel 19, and the feeding blade 20 extends into the inner cavity of the discharge section 12 through the through groove 18.

[0038] The feeding wheel 19 assists in the feeding of straw, increasing the density of the straw. The sheet-shaped feeding plate 20 increases the contact area with the straw, preventing the straw from being bent or stuck.

[0039] The present invention also includes a control method for a vertical burial machine, the steps of which are as follows:

[0040] S1. The frame 1 is dragged by a traction machine, and the hydraulic line of the traction machine provides rotational power to the drive motor 9 and the feed wheel 19.

[0041] S2, such as Figure 6 As shown, after the frame 1 moves into position and stops, the auger drill rod 2 starts to rotate, and the lifting telescopic cylinder 10 moves down to drill. After drilling to the set depth, the lifting telescopic cylinder 10 extends to pull out the auger drill rod 2, and the auger drill rod 2 stops rotating. Figure 7 As shown; at this time, the guide disc 3 acts as a positioning guide sleeve for the auger rod 2 to drill into the soil.

[0042] S3, such as Figure 8 As shown, the pusher cylinder 16 is activated, causing the pusher rod 6 to insert into the discharge window 5 and push out the straw in the discharge window 5 to complete the discharge. The straw slides down to the guide plate 3, and then the pusher cylinder 16 is reset. The feed wheel 19 rotates for a set time until the discharge window 5 is filled with straw again.

[0043] S4, such as Figure 9 As shown, the spiral drill rod 2, which holds the soil, is inserted into the guide plate 3 as the lifting telescopic cylinder 10 moves down, pressing any potentially stuck straw into the holes in the soil. The spiral drill rod 2 compacts the straw by inserting it into the holes. The spiral drill rod 2 then reverses and is pulled out, and the soil held on the spiral drill rod 2 is thrown back into the holes, sealing the holes and preventing soil moisture loss.

[0044] S5. Move frame 1 to the next position and repeat steps S2-S4 to complete the vertical burial of straw in the field.
