Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural soil-turning devices, and particularly relates to an automatic soil-turning structure for corn sowing. Background Art

[0002] Soil turning before corn planting can improve soil fertility, promote root development, reduce pests and diseases, and improve soil structure. With the progress of technology, large-scale soil-turning machinery is basically used for soil turning in farmland. However, there are also limitations. Due to various conditions such as the shape of the farmland, there are still dead corners after the soil-turning operation of large-scale soil-turning machinery. Especially at the corners and edges of the farmland, large-scale soil-turning machinery cannot cover them, and manual soil turning or small soil-turning machines need to be used. Currently, small soil-turning machines have the advantages of portability and convenient operation. It is precisely these advantages that make the functions of small agricultural machinery single. They cannot form ridges after soil turning. There are also small soil-turning machines equipped with ridging knives. However, when the ridging knives work, they deeply insert into the ground and push the soil to both sides to form ridges, which will bring great resistance to the soil-turning machine. Therefore, the energy consumption is relatively high. Summary of the Invention

[0003] The purpose of the utility model is to provide an automatic soil-turning structure for corn sowing to solve the problems existing in the prior art.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] An automatic soil-turning structure for corn sowing includes a support frame. Two limit members are rotatably sleeved at the bottom end of the support frame. A limit card is inserted jointly by the two limit members and the support frame. One end of each limit member is fixedly connected with a gear box. A soil-turning shaft is connected by a bearing in the gear box. One end of the soil-turning shaft penetrates through the gear box and is fixedly installed with a soil-turning knife. A passive gear is fixedly installed on the soil-turning shaft. A soil baffle is fixed above the gear box. A driving device is installed on the soil baffle. The output end of the driving device is provided with an active gear that penetrates through the soil baffle and the gear box. The active gear meshes with the passive gear.

[0006] Further, a handrail is fixed at the top end of the support frame. The handrail is U-shaped. Control buttons are installed at both ends of the handrail. The two control buttons are electrically connected to the two driving devices respectively.

[0007] Further, a tray is welded at the bottom end of the support frame. A column is provided on the tray. The outer wall of the upper part of the column is in the shape of external screw threads. One end of the column with external screw threads is sleeved with a pull rod. A nut is screwed on the column above the pull rod.

[0008] Further, one end of the pull rod is in a ring shape. The ring-shaped end of the pull rod is sleeved on the column. The other end of the pull rod is welded with an arc-shaped plate. The arc-shaped plate is bolted to the support rod.

[0009] Further, the limiting member is sleeved on the upright column of the support frame. The two limiting members are distributed up and down and are located between the pull rod and the tray. A number of limiting holes are symmetrically arranged on the limiting member.

[0010] Further, the tray is circular. Two fixing holes are symmetrically formed on the tray. The connection line between the two fixing holes is perpendicular to the traveling direction of the automatic soil turning structure.

[0011] Further, the limiting card is U-shaped. The two ends of the limiting card respectively pass through two symmetrically arranged limiting holes on the limiting member and then pass through the two fixing holes on the tray.

[0012] Further, both the driving gear and the driven gear are spiral bevel gears.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model can not only turn the soil, but also form ridges while turning the soil. It does not require a special ridging knife, has a small traveling resistance, so the energy consumption is low, and it is suitable for small agricultural equipment.

[0015] 2. By rotating the two limiting members on the upright column to adjust the angle of the soil turning knife, the angle can be adjusted as needed, so as to realize soil turning or soil turning and ridging at the same time.

[0016] 3. The limiting member can be limited by the limiting card. By pulling out or inserting into the limiting hole, the switching between the rotating state and the fixed state of the limiting member can be realized. The operation is convenient and the design is reasonable.

[0017] 4. The pull rod is used to strengthen the connection between the support frame and the upright column. The pull rod can be detachably removed to facilitate the installation of the two limiting members. Description of the Drawings

[0024] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further describes the present utility model in detail in conjunction with specific embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] As Figures 1-5 shown, an automatic soil-turning structure for corn sowing includes a support frame 1. Two limiting members 2 are rotatably sleeved at the bottom end of the support frame 1. A limiting card 3 is inserted jointly by the two limiting members 2 and the support frame 1. One end of each limiting member 2 is fixedly connected with a gear box 4. A soil-turning shaft 5 is connected by a bearing in the gear box 4. One end of the soil-turning shaft 5 penetrates through the gear box 4 and is fixedly installed with a soil-turning knife 6. A driven gear 7 is fixedly installed on the soil-turning shaft 5. A soil retaining plate 9 is fixed above the gear box 4. A driving device 10 is installed on the soil retaining plate 9. The output end of the driving device 10 is provided with a driving gear 8 which penetrates through the soil retaining plate 9 and the gear box 4. The driving gear 8 meshes with the driven gear 7.

[0026] A hand-held frame 11 is fixed at the top end of the support frame 1. The hand-held frame 11 is U-shaped. Control buttons 18 are installed on both ends of the hand-held frame 11. The two control buttons 18 are electrically connected to the two driving devices 10 respectively. The control buttons 18 are used to control the two driving devices 10 respectively, and drive the soil-turning knife 6 to rotate through the driving devices 10.

[0027] A tray 12 is welded at the bottom end of the support frame 1. A column 13 is provided on the tray 12. The outer wall of the upper part of the column 13 is in the shape of external screw threads. One end of the column 13 with external screw threads is sleeved with a tie rod 14. A nut 15 is screwed on the column 13 above the tie rod 14. The tray 12 is used to carry the limiting member 2 and other components. The column 13 is used to sleeve the two limiting members 2. The nut 15 is used to press the tie rod 14, so as to clamp the two limiting members 2 between the tie rod 14 and the tray 12.

[0028] One end of the tie rod 14 is in a ring shape. The ring-shaped end of the tie rod 14 is sleeved on the column 13. The other end of the tie rod 14 is welded with an arc-shaped plate 16. The arc-shaped plate 16 is bolted to the support rod. The tie rod 14 is used to strengthen the connection between the support frame 1 and the column 13. The tie rod 14 can be detachably moved, so as to facilitate the installation of the two limiting members 2.

[0029] The limiting member 2 is sleeved on the column 13 of the support frame 1. The two limiting members 2 are distributed up and down and are located between the pull rod 14 and the tray 12. A number of limiting holes 17 are symmetrically arranged on the limiting member 2. The two limiting members 2 can rotate on the column 13 so as to adjust the angle.

[0030] The limiting card 3 is U-shaped. The two ends of the limiting card 3 respectively pass through two symmetrically arranged limiting holes 17 on the limiting member 2 and then penetrate through the tray 12. After the limiting card 3 is inserted into the limiting holes 17 of the two limiting members 2 and the fixing holes 19 of the tray 12, the two limiting members 2 are fixed on the tray 12 and thus cannot rotate, so as to carry out the soil turning work.

[0031] The driving gear 8 and the driven gear 7 are both spiral bevel gears.

[0032] The working principle of the utility model is as follows:

[0033] When carrying out the soil turning operation, first adjust the angles of the soil turning blades 6 on both sides of the soil turner. After pulling out the limiting card 3, the two limiting members 2 can rotate freely on the column 13. Since the soil turning blades 6 are connected to the limiting members 2 through the gear box 4, they can rotate following the rotation of the limiting members 2. Among the several limiting holes 17 on the limiting member 2, the connection line of two symmetrically arranged limiting holes 17 is parallel to the soil turning shaft 5. Rotate the limiting member 2 to align these two limiting holes 17 with the two fixing holes 19 on the tray 12. In this way, the soil turning shaft 5 is perpendicular to the advancing direction of the automatic soil turning structure, and the soil turning blade 6 is perpendicular to the soil turning shaft 5. That is to say, the working surface of the soil turning blade 6 is parallel to the advancing direction of the automatic soil turning structure. At this time, insert the limiting card 3 into the limiting holes 17 of the two limiting members 2 and the fixing holes 19 of the tray 12, so as to limit the rotation of the two limiting members 2. At this time, hold the handrail frame 11 and press the two control buttons 18 to start the two driving devices 10. The driving gear 8 of the driving device 10 drives the soil turning shaft 5 to rotate through the meshing driven gear 7, and the soil turning blade 6 also rotates following the soil turning shaft 5. The operator holds the handrail frame 11 and moves forward, so as to carry out the soil turning operation on the farmland.

[0034] When ridging operation is required after soil turning, first adjust the angles of the soil turning blades 6 on both sides of the soil turner. After pulling out the limit card 3, the two limit pieces 2 can rotate freely on the column 13. Since the soil turning blade 6 is connected to the limit piece 2 through the gear box 4, it can rotate following the rotation of the limit piece 2. Among several limit holes 17 on the limit piece 2, the connection line of two symmetric limit holes 17 forms a certain angle with the axis of the soil turning shaft 5. Select a suitable limit hole 17 as needed, and rotate the limit piece 2 to align the two selected limit holes 17 with the two fixing holes 19 on the tray 12. Note that the limit holes 17 selected by the two limit pieces 2 should correspond to each other. In this way, the soil turning shaft 5 forms a certain angle with the advancing direction of the automatic soil turning structure, and the soil turning blade 6 is perpendicular to the soil turning shaft 5. That is to say, the working surface of the soil turning blade 6 forms a certain angle with the advancing direction of the automatic soil turning structure, and the working surfaces of the two soil turning blades 6 form a structure with a pointed front and a wide rear. At this time, insert the limit card 3 into the limit holes 17 of the two limit pieces 2 and the fixing holes 19 of the tray 12, which restricts the rotation of the two limit pieces 2. At this time, hold the handrail 11 and press the two control buttons 18 to start the two driving devices 10. The driving gear 8 of the driving device 10 drives the soil turning shaft 5 to rotate through the engaged driven gear 7, and the soil turning blade 6 also rotates following the soil turning shaft 5. The operator holds the handrail 11 and moves forward. While turning the soil, the soil turning blade 6 throws the soil to both sides of the automatic soil turning structure, thus forming ridges.

[0035] Since the soil turning blade 6 forms ridges while turning the soil and does not require a special ridging knife, the advancing resistance is small and the energy consumption is low. And generally, small agricultural equipment features portability and convenient operation and does not require large power to drive. Therefore, the utility model is suitable for small agricultural equipment.

[0036] The embodiments described above are only used to describe the preferred embodiments of the utility model, and do not limit the concept and scope of the utility model. Without departing from the design concept of the utility model, various variations and improvements made by those of ordinary skill in the art to the technical solutions of the utility model should all fall within the protection scope of the utility model.

[0037] The technologies, shapes, and structures not described in detail in the utility model are all well-known technologies.
