Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically a cotton seedling support machine. Background Technology

[0002] Cotton is one of the world's most important field crops and a vital agricultural product related to national economy and people's livelihood. Cotton is a multi-purpose crop, producing fiber, oil, and feed. Each unit weight of cotton yields 40% lint and 60% cottonseed, with oil and protein content similar to soybeans. Cotton fiber can be made into various fabrics, from lightweight, transparent voile to thick canvas and velvet, suitable for making various clothing, furniture fabrics, and industrial textiles. Developing cotton production not only promotes the textile industry but also supports the development of oilseed and feed industries. Cotton is also a preferred crop for utilizing moderately saline-alkali land. Among major crops, cotton is the most salt-tolerant, drought-resistant, and flood-resistant, and is hailed as a "pioneer crop" for developing and utilizing saline-alkali land. Cotton is a fundamental guarantee for farmers' income in cotton-growing areas. In advantageous cotton-growing regions, cotton is a pillar product for increasing cotton farmers' income and an important source of their economic income.

[0003] Currently, in single-cropping cotton-producing areas, especially coastal saline-alkali cotton-growing areas, the main technology promoted is cotton planting with plastic film mulching, and the cotton sowing process has been fully mechanized. However, in cotton fields with plastic film mulching, after the cotton seedlings emerge, a small hole needs to be manually opened in the mulch to release the seedlings; otherwise, the seedlings cannot break through the mulch and grow normally. When releasing the cotton seedlings, because the hole in the mulch is opened, there is a large gap at the base of the seedlings after they emerge from the mulch, which causes three problems: First, cotton seedlings emerge during the transition from spring to summer, when the temperature is unstable. On sunny days, the high temperature generated by the mulch at noon can easily cause seedling burn by escaping through the gap, while at night, cold air can enter through the gap, which is not conducive to heat preservation; second, the lack of mulch in the gap allows weeds to grow rapidly; and third, because cotton seedlings are relatively fragile, the large gap makes them prone to lodging. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems and provide a cotton seedling support machine.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A cotton seedling support machine includes a frame installed on agricultural machinery, a rotating shaft disposed below the frame, and seedling support mechanisms symmetrically disposed on the rotating shaft;

[0007] The seedling support mechanism includes a turntable fixed on the rotating shaft, mounting grooves evenly arranged on the turntable along the circumferential direction, and a cutting tool arranged in the mounting groove. The turntable is provided with a locking mechanism for simultaneously locking several cutting tools.

[0008] The locking mechanism includes a support plate installed on the outside of the turntable, a positioning rod passing through the support plate, the turntable and the mounting groove from the outside to the inside, one end of the positioning rod passing through the cutter in the mounting groove, and a first driving mechanism for driving multiple positioning rods to move synchronously on the support plate.

[0009] The first driving mechanism includes a rotating ring disposed on the outside of the support plate and rotating on the outside of the support plate, gears evenly disposed on the inside of the rotating ring, and a moving rod disposed on the outside of the rotating ring and moving along the diameter direction of the rotating ring. The rotating ring has a rack on its inside that meshes with the gear, and the moving rod has a rack on its side that meshes with the gear. The moving rod and the rotating ring are slidably connected by a guide rail slider pair. A connecting plate is provided at one end of the outer side of the moving rod. The connecting plate has an elongated hole. The elongated hole at the right end is inclined to the right from the inside to the outside, and the elongated hole at the left end is inclined to the left from the inside to the outside. A driving rod that mates with the elongated hole is provided at one end of the outer side of the positioning rod. A second driving mechanism for driving the rotating ring to rotate is provided on the frame.

[0010] Furthermore, the frame is provided with side plates at both ends, and the two ends of the rotating shaft are rotatably connected to the side plates through bearings.

[0011] Furthermore, the upper end of the frame is equipped with a motor that drives the rotating shaft to rotate.

[0012] Furthermore, the cutting tool includes a vertical portion located within the mounting groove and a horizontal portion disposed at one end of the outer side of the vertical portion.

[0013] Furthermore, the support plate is connected to the turntable via a sleeve, and the positioning rod passes through the sleeve.

[0014] Furthermore, the cutting tool is provided with a through hole that mates with the positioning rod.

[0015] Furthermore, the second driving mechanism includes a swing arm rotatably connected to the frame at its front end and a pressure rod disposed at the lower end of the swing arm.

[0018] Furthermore, the positioning mechanism includes a support plate disposed on the frame, and the support plate is provided with positioning bolts for positioning the angle of the swing arm.

[0019] The beneficial effects of this invention are:

[0020] 1. The present invention includes a frame installed on agricultural machinery, a rotating shaft set below the frame, and a seedling support mechanism symmetrically arranged on the rotating shaft. When cotton seedlings are released, there will be a large gap at the cotton roots. When the rotating shaft rotates, the seedling support mechanism can block the gap to prevent weeds from growing, and at the same time achieve the functions of heat preservation, moisture retention, and preventing cotton from lodging.

[0021] 2. The locking mechanism in this invention includes a support plate installed on the outside of the turntable, and positioning rods that pass through the support plate, the turntable, and the mounting groove sequentially from the outside to the inside. One end of the positioning rod passes through the cutter in the mounting groove. The support plate is provided with a first driving mechanism that drives multiple positioning rods to move synchronously. The first driving mechanism drives several positioning rods to move synchronously, thereby achieving synchronous fixing and loosening of the cutter. When multiple cutters need to be replaced at the same time, the first driving mechanism drives several positioning rods to move outward synchronously, thereby achieving synchronous loosening of the cutter. Existing cutters are fixed with bolts. When replacing multiple cutters, it is necessary to loosen the bolts one by one, which is time-consuming and laborious. This application loosens the cutters at the same time, which facilitates the replacement of multiple cutters.

[0022] 3. The first driving mechanism in this invention includes a rotating ring disposed on the outside of the support plate and rotating thereon, gears evenly disposed on the inner side of the rotating ring, and a moving rod disposed on the outside of the rotating ring and moving along the diameter of the rotating ring. A connecting plate is provided at one end of the outer side of the moving rod, and an elongated hole is provided on the connecting plate. A driving rod that mates with the elongated hole is provided at one end of the outer side of the positioning rod. A second driving mechanism for driving the rotating ring to rotate is provided on the frame. When a tool needs to be replaced, the rotating ring is driven to rotate backward by the second driving mechanism. Under the action of the rack, several gears rotate synchronously. Under the action of the gears and the rack on the moving rod, the moving rod moves synchronously inward. Under the action of the elongated hole and the driving rod, the positioning rod moves synchronously outward, separating from the tool, facilitating the simultaneous replacement of several tools.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0032] like Figure 1 and Figure 2 As shown, a cotton seedling support machine includes a frame 1 installed on agricultural machinery, a rotating shaft 2 located below the frame 1, and seedling support mechanisms symmetrically arranged on the rotating shaft 2. When cotton seedlings are released, there will be large gaps at the cotton roots. When the rotating shaft 2 rotates, the seedling support mechanism can block these gaps to prevent weed growth, while also achieving the functions of heat preservation, moisture retention, and preventing cotton from lodging.

[0033] like Figure 4 As shown, the seedling support mechanism includes a turntable 3 fixed on the rotating shaft 2, mounting grooves 4 evenly arranged on the turntable 3 along the circumferential direction, and cutters 5 arranged in the mounting grooves 4. The rotating shaft 2 passes through the middle position of the turntable 3, and the turntable 3 is fixed on the rotating shaft 2. The turntable 3 is provided with a locking mechanism for synchronously locking several cutters 5. When the rotating shaft 2 rotates, the turntable 3 rotates synchronously, driving the cutters 5 to rotate. The cutters 5 lift up the soil and fill the gaps at the roots of the cotton.

[0034] like Figure 3As shown, the locking mechanism includes a support plate 6 installed on the outside of the turntable 3, and positioning rods 7 passing through the support plate 6, the turntable 3, and the mounting groove 4 from the outside to the inside. One end of the positioning rod 7 passes through the cutter 5 in the mounting groove 4. The support plate 6 is provided with a first driving mechanism that drives multiple positioning rods 7 to move synchronously. The first driving mechanism drives multiple positioning rods 7 to move synchronously, thereby realizing the synchronous fixing and loosening of the cutter 5. When multiple cutters need to be replaced at the same time, the first driving mechanism drives multiple positioning rods 7 to move outward synchronously, thereby realizing the synchronous loosening of the cutters. Existing cutters are fixed by bolts. When replacing multiple cutters, it is necessary to loosen the bolts one by one, which is time-consuming and laborious. However, this application loosens the cutters at the same time, which facilitates the replacement of multiple cutters.

[0035] like Figure 3 and Figure 5 As shown, the first driving mechanism includes a rotating ring 8 disposed on the outside of the support plate 6 and rotating thereon; gears 9 evenly disposed on the inner side of the rotating ring 8; and a moving rod 10 disposed on the outside of the rotating ring 8 and moving along the diameter of the rotating ring 8. The gears 9 are disposed on the support plate 6 and rotate thereon. A plurality of gears 9 are evenly disposed along the circumference of the rotating ring 8. A rack meshing with the gears 9 is provided on the inner side of the rotating ring 8. A rack meshing with the gears 9 is provided on the side of the moving rod 10. The moving rod 10 and the rotating ring 8 are slidably connected via a guide rail slider pair. A connecting plate 11 is provided at one outer end of the moving rod 10. The connecting plate 11 has an elongated hole 12. The elongated hole 12 at the right end is inclined to the right from the inside out, and the elongated hole 12 at the left end is inclined to the left from the inside out. The inner end is located near the rotating shaft. A driving rod 13 that mates with the elongated hole 12 is provided at one outer end of the positioning rod 7. The outer end is located near the side plate. The connecting plate 11 and the driving rod 13 are symmetrically arranged. Each connecting plate 11 has an elongated hole 12. A second driving mechanism for driving the rotating ring 8 to rotate is provided on the frame 1. When the tool 5 needs to be replaced, the rotating ring 8 is driven to rotate backward by the second driving mechanism. Under the action of the rack, several gears 9 rotate synchronously. Under the action of the gears 9 and the rack on the moving rod 10, the moving rod 10 moves synchronously inward. Under the action of the elongated hole 12 and the driving rod 13, the positioning rod 7 moves synchronously outward and separates from the tool 5, which facilitates the simultaneous replacement of several tools 5.

[0036] like Figure 1 As shown, the frame 1 has side plates 14 at both ends, and the two ends of the rotating shaft 2 are rotatably connected to the side plates 14 through bearings.

[0037] like Figure 1 As shown, the upper end of the frame 1 is provided with a motor 15 that drives the rotating shaft 2 to rotate, and the output end of the motor 15 is provided with a gearbox connected to the rotating shaft 2.

[0038] like Figure 4As shown, the cutter 5 includes a vertical part located in the mounting groove 4 and a horizontal part located at one end of the outer side of the vertical part. By setting the cutter 5 to a bent shape, when the rotating shaft 2 rotates, the cutter 5 can lift the soil and fill the gaps at the roots of the cotton with the soil.

[0039] like Figure 5 As shown, the support plate 6 is connected to the turntable 3 through the sleeve 16, and the positioning rod 7 passes through the sleeve 16, which serves as a guide.

[0040] The cutting tool 5 is provided with a through hole that cooperates with the positioning rod 7.

[0041] like Figure 3 and Figure 6 As shown, the second driving mechanism includes a swing arm 17 rotatably connected to the frame 1 at its front end, and a pressure rod 18 disposed at the lower end of the swing arm 17. The upper end of the pressure rod 18 is rotatably connected to the middle position of the swing arm 17, and the lower end of the pressure rod 18 is provided with an arc-shaped pressure head 19. Several crossbars 20 that cooperate with the arc-shaped pressure head 19 are provided on the outer side of the rotating ring 8. The frame 1 is provided with a positioning mechanism for positioning the angle of the swing arm 17. When it is necessary to change the tool, the arc-shaped pressure head 19 cooperates with the crossbars 20, and the rotating ring 8 can be driven to rotate through the swing arm 17 and the pressure rod 18.

[0042] The frame 1 is provided with an opening 21 for the pressure bar 18 to pass through.

[0043] The end of the swing arm 17 is provided with a handle 22, which facilitates the swinging of the swing arm 17.

[0044] like Figure 1 As shown, the positioning mechanism includes a support plate 23 set on the frame 1. The support plate 23 is provided with a positioning bolt 24 for positioning the angle of the swing rod 17. When working, the swing rod 17 is lifted and the positioning bolt 24 positions the swing rod 17 to prevent the swing rod 17 from falling and thus not affecting the seedling support work.
