Description

Technical Field

[0001] The invention relates to the technical field of rotary tillers, in particular to an anti-adhesion self-cleaning rotary tiller. Background Art

[0002] A rotary tiller is a tilling machine that is used in conjunction with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil crushing ability and flat surface after plowing. It can also cut up the root stubble buried below the surface, making it easier for the seeder to operate and providing a good seed bed for later sowing.

[0003] The rotary tilling blades of existing rotary tillers are easily adhered to soil when working. If they are not cleaned in time, the moisture in the soil will aggravate the erosion of the rotary tilling blades, which is not conducive to the life of the structure. In addition, the adhered soil will be entrained and fall onto the road during transfer, which is not conducive to maintaining the cleanliness of the road environment. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an anti-adhesion self-cleaning rotary tiller, which solves the problem that adhered soil will aggravate the erosion of the rotary tiller blade and is not conducive to maintaining the road environment.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an anti-adhesion self-cleaning rotary tiller, comprising a main frame, main side panels are installed at both ends of the bottom of the main frame, straight grooves are opened at the front and rear edges of the inner sides of the main side panels, the bottoms of the main side panels are rotatably connected with matching U-shaped side panels, the outer edges of the inner sides of the U-shaped side panels are opened with U-shaped grooves, the top ends of the U-shaped grooves are respectively connected to the bottom ends of the straight grooves, a water injection hole is opened on the left side of the interior of the main frame, and a water injection hole is opened on the rear side of the interior of the main frame There is a through groove, and a winding rod is rotatably connected to the top rear side of the main frame, and a closed plate rolling curtain is wound on the outside of the winding rod, and the other end of the closed plate rolling curtain passes through the through groove and extends to the inside of the straight groove on the rear side. The closed plate rolling curtain can move in the connecting space between the through groove, the straight groove and the U-shaped groove. A first hydraulic motor is installed at one end of the winding rod, and a second hydraulic motor is installed in the middle of the rear end of the main frame. A friction wheel is installed at the driving end of the second hydraulic motor, and the front side of the friction wheel is tightly fitted to the rear side of the closed plate rolling curtain.

[0006] Preferably, support pads are installed at the bottom of the U-shaped side panels.

[0007] Preferably, a short rod is installed in the middle part of the outer side of the U-shaped side plate, and the outer end of the short rod is rotatably connected to a hydraulic cylinder, and the cylinder body side surfaces of the hydraulic cylinder are rotatably connected to the two sides of the top of the main frame respectively.

[0008] Preferably, a main shaft is provided below the main frame, and two ends of the main shaft are rotatably connected to the middle part of the lower side of the main side plate respectively, and a plurality of rotary tillage blades are installed outside the main shaft.

[0009] Preferably, a first sprocket is installed in the middle of the main shaft, a gear box is installed in the middle of the top of the main frame, a driven shaft is rotatably connected inside the gear box, a second sprocket is installed on the outer side of the driven shaft, and the first sprocket is connected to the second sprocket by a chain.

[0010] Preferably, a first bevel gear is installed on the other side of the driven shaft, a driving shaft is rotatably connected to the middle of the front side of the gear box, a second bevel gear is installed on the rear end of the driving shaft, and the second bevel gear is meshingly connected to the first bevel gear.

[0011] Preferably, a connecting bracket is installed on the top front side of the main frame, and traction brackets are installed on both sides of the front end of the main frame.

[0012] Working principle: The rotary tiller is connected to the tractor through the connecting bracket and traction bracket technology commonly used in the rotary tiller field. Similarly, the driving shaft is connected to the rear output shaft of the tractor, and the first hydraulic motor, the second hydraulic motor and the hydraulic cylinder are connected to the hydraulic pump station of the tractor. The rear output shaft can drive the driving shaft to rotate, and then the second bevel gear and the first bevel gear drive the driven shaft to rotate. The driven shaft is then driven by a chain, so that the main shaft drives the external rotary tillage blade to rotate, and finally the purpose of rotary tillage is achieved. When rotary tillage is working, the hydraulic cylinder is controlled to shorten, and then the U-shaped side plate can be turned outward and upward through the short rod, so that the bottom of the rotary tillage blade can penetrate into the soil to ensure the progress of the work. After the rotary tillage work is completed, the hydraulic cylinder extends, so that the U-shaped side plate is in a vertical state, and then the first hydraulic motor and the second hydraulic motor are controlled to work simultaneously. The rotation direction of the first hydraulic motor is the direction of releasing the closing plate roller shutter, and the rotation direction of the second hydraulic motor is the direction of causing the closing plate roller shutter to move downward through the friction force between the friction wheel and the closing plate roller shutter. Therefore, under the action of the above-mentioned common external force, the closing plate roller shutter moves along the through groove, the straight groove and the U-shaped groove until it completely wraps the rotary tillage blade together with the main frame to form a closed space, and then clean water is injected into the above-mentioned closed space through the water injection hole. At this time, the rotary tillage blade is driven to rotate, and the clean water is continuously stirred by the rotary tillage blade, thereby preventing the rotary tillage blade from adhering to the soil and achieving a self-cleaning effect. When the rotary tiller is not working and needs to be removed, the hydraulic cylinder is extended to make the U-shaped side plate vertical. At this time, the support of the support pad can prevent the bottom of the rotary tillage blade from sitting on the ground, thereby achieving the purpose of protecting the rotary tillage blade.

[0013] The present invention provides an anti-adhesion self-cleaning rotary tiller. It has the following beneficial effects:

[0014] The present invention pushes and pulls the closing plate roller shutter so that it and the main frame completely wrap the rotary tillage blade to form a closed space, and then injects clean water into the closed space through the water injection hole. At this time, the rotary tillage blade is driven to rotate, and the clean water is continuously stirred by the rotary tillage blade, thereby preventing the rotary tillage blade from adhering to the soil and achieving a self-cleaning effect. In addition, during the stirring process, the clean water will splash around due to inertia, so that the bottom of the main frame and other parts can be cleaned, thereby achieving the purpose of comprehensive cleaning and solving the problem that the adhered soil will aggravate the erosion of the rotary tillage blade and is not conducive to maintaining the road environment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example:

[0024] like Figure 1-6As shown, an embodiment of the present invention provides an anti-adhesion self-cleaning rotary tiller, comprising a main frame 1, main side panels 8 are installed at both ends of the bottom of the main frame 1, a main shaft 16 is arranged below the main frame 1, and both ends of the main shaft 16 are rotatably connected to the middle part of the lower side of the main side panel 8, a plurality of rotary tilling blades are installed outside the main shaft 16, straight grooves 9 are provided at the front and rear edges of the inner side surfaces of the main side panels 8, and the bottom of the main side panels 8 are rotatably connected to matching U-shaped side panels 10, and U-shaped grooves 11 are provided at the outer edges of the inner sides of the U-shaped side panels 10, and the top ends of the U-shaped grooves 11 are respectively connected to the bottom ends of the straight grooves 9, and the inner surface of the main frame 1 A water injection hole 15 is provided on the left side of the main frame 1, a through groove 6 is provided on the inner rear side of the main frame 1, a winding rod 2 is rotatably connected to the top rear side of the main frame 1, a closed plate roller shutter 7 is wound on the outside of the winding rod 2, the other end of the closed plate roller shutter 7 passes through the through groove 6 and extends to the inside of the rear straight groove 9, the closed plate roller shutter 7 can move in the connecting space between the through groove 6, the straight groove 9 and the U-shaped groove 11, a first hydraulic motor 3 is installed at one end of the winding rod 2, a second hydraulic motor 4 is installed in the middle of the rear end of the main frame 1, a friction wheel 5 is installed at the driving end of the second hydraulic motor 4, and the front side of the friction wheel 5 is tightly fitted with the rear side of the closed plate roller shutter 7.

[0025] In this embodiment, Figure 5 As shown, after the rotary tillage work is completed, the U-shaped side plate 10 is in a vertical state, and then the first hydraulic motor 3 and the second hydraulic motor 4 are controlled to work simultaneously, wherein the rotation direction of the first hydraulic motor 3 is the direction of releasing the closing plate roller shutter 7, and the rotation direction of the second hydraulic motor 4 is the direction of causing the closing plate roller shutter 7 to move downward through the friction force between the friction wheel 5 and the closing plate roller shutter 7, so that the closing plate roller shutter 7 moves along the through groove 6, the straight groove 9 and the U-shaped groove 11 under the action of the above-mentioned common external force until it completely wraps the rotary tillage blade together with the main frame 1 to form a closed space, and then clean water is injected into the above-mentioned closed space through the water injection hole 15, and then the rotary tillage blade is driven to rotate, and the clean water is continuously stirred by the rotary tillage blade, thereby preventing the rotary tillage blade from adhering to the soil and achieving a self-cleaning effect.

[0026] When the rotary tillage blade continuously stirs the cleaning water, the soil adhered to the rotary tillage blade can be cleaned by relying on the impact of the cleaning water. At the same time, during the stirring process, the cleaning water will also splash around due to the action of inertia, so that the bottom of the main frame 1 and other parts can also be cleaned, achieving the purpose of comprehensive cleaning.

[0027] In this embodiment, the closed plate rolling curtain 7 is formed by a plurality of plates connected end to end, and adjacent plates can rotate relative to each other, so that the closed plate rolling curtain 7 can be opened or closed by pulling or pushing each other.

[0028] Furthermore, a support pad 12 is installed at the bottom of the U-shaped side panel 10, and a short rod 13 is installed at the middle of the outer side of the U-shaped side panel 10.

[0029] like Figure 1 , Figure 6 As shown, the telescopic action of the hydraulic cylinder 14 can drive the U-shaped side plate 10 to deflect through the short rod 13. For example, during rotary tillage operation, the hydraulic cylinder 14 is controlled to shorten, and then the U-shaped side plate 10 can be flipped outward and upward through the short rod 13, so that the bottom of the rotary tiller blade can penetrate deep into the soil to ensure the progress of the work. When the rotary tiller is not in operation and needs to be unloaded, the hydraulic cylinder 14 is extended to make the U-shaped side plate 10 in a vertical state.

[0030] Furthermore, a connecting bracket 22 is installed on the top front side of the main frame 1 , and traction brackets 23 are installed on both sides of the front end of the main frame 1 .

[0031] Furthermore, a first sprocket is installed in the middle of the main shaft 16, a gear box 17 is installed in the middle of the top of the main frame 1, the gear box 17 is rotatably connected to the inside of the driven shaft 18, a second sprocket is installed on the outer side of the driven shaft 18, the first sprocket is connected to the second sprocket by a chain, a first bevel gear 19 is installed on the other side of the driven shaft 18, the middle of the front side of the gear box 17 is rotatably connected to the drive shaft 21, the rear end of the drive shaft 21 is installed with a second bevel gear 20, and the second bevel gear 20 is meshingly connected with the first bevel gear 19.

[0032] The rotary tiller is connected to the tractor through the connecting bracket 22 and the traction bracket 23 technology commonly used in the rotary tiller field. Similarly, the driving shaft 21 is connected to the rear output shaft of the tractor, and the first hydraulic motor 3, the second hydraulic motor 4 and the hydraulic cylinder 14 are connected to the hydraulic pump station of the tractor. The driving shaft 21 can be driven to rotate through the rear output shaft, and then the driven shaft 18 is driven to rotate through the second bevel gear 20 and the first bevel gear 19. The driven shaft 18 is driven by a chain, so that the main shaft 16 drives the external rotary tiller blade to rotate, and finally the purpose of rotary tillage is achieved.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
