Description

Technical Field

[0001] This application belongs to the field of agricultural machinery technology, and specifically relates to a rotary grapevine soil clearing device and soil clearing machine. Background Technology

[0002] In northern regions where winter temperatures drop below freezing, to protect some cold-sensitive grape varieties from surviving the winter, it's necessary to bury the vines before the temperature plummets. This involves digging shallow pits along the direction the vines are lying, pressing the vines into these pits in the same direction, and then covering them with soil to form continuous mounds. Once the temperature warms up and the vines begin to sprout, the soil needs to be removed. Currently, manual labor using hand-held scrapers removes the loose soil from the vines, but this process is labor-intensive and inefficient. While some technologies use tractors to break up the soil mounds, this method requires repeated steps, preventing the vines from being fully exposed, and the depth of breaking the soil cannot be precisely controlled, potentially damaging new buds and reducing the vine's survival rate. Summary of the Invention

[0003] Based on the aforementioned background and technical needs, this application discloses a rotary grapevine soil-cleaning device and soil-cleaning machine to solve the problem of poor soil-cleaning effect and easy damage to grapevines in the prior art.

[0004] To achieve the above objectives, the technical solution of this application is as follows:

The walking frame is equipped with supporting rollers. The rotary soil-cleaning assembly includes a first working plate, a soil-cleaning brush turntable, and a soil-cleaning scraper turntable. The soil-cleaning brush turntable and the soil-cleaning scraper turntable are rotatably mounted sequentially on the underside of the first working plate along the traveling direction of the walking frame. The distance between the soil-cleaning brush turntable and the first working plate is greater than the distance between the soil-cleaning scraper turntable and the first working plate. The drive assembly is drively connected to the soil-cleaning brush turntable and the soil-cleaning scraper turntable, and is used to drive the soil-cleaning brush turntable and the soil-cleaning scraper turntable to rotate. The lifting assembly is located on one side of the walking frame and connected to the first working plate, and is used to drive the first working plate to move up and down in the height direction.

[0006] Preferably, the lifting assembly includes a second working plate and an adjusting screw. The second working plate is horizontally disposed on one side of the traveling frame, and the adjusting screw passes through the second working plate along the direction of gravity, with the lower end of the adjusting screw cooperating with and connected to the first working plate.

[0007] Preferably, the drive assembly includes a motor, a main drive wheel, and a transmission wheel. The motor is mounted on the first working plate or the second working plate. There are at least two transmission wheels, and the transmission wheels are respectively connected to the soil cleaning brush turntable and the soil cleaning scraper turntable via a drive shaft. The main drive wheel is connected to the drive shaft of the motor, and the main drive wheel is synchronously connected to the transmission wheel via a drive belt.

[0008] Preferably, one end of the motor is fixed to the second working plate, and the drive shaft of the motor is a spline shaft. The main drive wheel is rotatably connected to the first working plate through a spline sleeve, and the spline shaft and the spline sleeve slide and are in transmission cooperation.

[0009] Preferably, a plurality of scraping blades are evenly arranged on the lower side of the soil cleaning scraper turntable around the drive shaft, the widths of the scraping blades are not equal, and the widths of adjacent scraping blades gradually increase along the rotation direction of the soil cleaning scraper turntable.

[0010] Preferably, a plurality of brush heads are evenly arranged on the lower side of the soil cleaning brush turntable around the drive shaft, the bristle lengths of the plurality of brush heads are not equal, and the bristle lengths of adjacent brush heads gradually increase along the rotation direction of the soil cleaning brush turntable.

The towing drive device is detachably connected to the rotary grapevine soil clearing device, and the towing drive device is used to drive the rotary grapevine soil clearing device to move.

[0012] By adopting the above technical solution, compared with the prior art, this application has at least the following beneficial effects:

[0013] The height of the first working plate can be adjusted by the lifting component, which facilitates the adjustment of the cleaning depth and soil breaking depth of the rotary grapevine soil cleaning device to adapt to soil ridges of different heights. During the movement of the soil cleaning scraper turntable, the soil above the grapevine is first scraped off, and then the soil cleaning brush turntable sweeps away the loose soil on the surface of the grapevine as it moves forward. The entire cleaning process only requires the walking frame to travel along the soil ridge once in one direction, which can expose the grapevine from the soil ridge. This not only improves the efficiency of the early soil cleaning operation of the grapevine, but also makes it less likely to cause hard damage to the new buds on the grapevine during the soil cleaning process, thereby improving the survival rate of the grapevine.

[0022] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The present application will be further described in detail with reference to specific embodiments.

[0023] A rotary grapevine soil-cleaning device includes a walking frame 10, a rotary soil-cleaning assembly 20, a drive assembly 30, and a lifting assembly 40. The walking frame 10 comprises a horizontally placed frame and supporting rollers 15 at the bottom of the frame. The supporting rollers 15 support the frame to a certain height, allowing the walking frame 10 to move along the length of the grapevine ridges while being towed. The rotary soil-cleaning assembly 20 includes a first working plate 21, a soil-cleaning brush turntable 22, and a soil-cleaning scraper turntable 23. The soil-cleaning brush turntable 22 and the soil-cleaning scraper turntable 23 are rotatably mounted sequentially below the first working plate 21 along the traveling direction of the walking frame 10, and the vertical distance between the soil-cleaning brush turntable 22 and the first working plate 21 is greater than that between the soil-cleaning scraper turntable 23 and the first working plate 21. The vertical distance between the turntable 23 and the first working plate 21, i.e., the horizontal position of the soil cleaning brush turntable 22 is lower than the horizontal position of the soil cleaning scraper turntable 23; the drive assembly 30 includes at least one drive device for outputting rotational driving force and a set of mechanical transmission mechanisms. The drive assembly 30 is connected to the soil cleaning brush turntable 22 and the soil cleaning scraper turntable 23 through mechanical transmission, so that the drive device that can output rotational driving force drives the soil cleaning brush turntable 22 and the soil cleaning scraper turntable 23 to rotate respectively; the lifting assembly 40 is set on one side of the walking frame 10 and connected to one side of the first working plate 21. The lifting assembly 40 can drive the first working plate 21 to move along the height direction to adjust the soil cleaning depth of the soil cleaning brush turntable 22 and the soil cleaning scraper turntable 23.

[0024] When using the above-mentioned device, before the walking frame 10 moves directionally along the extension direction of the soil ridge at the bottom of the grapevine, the height of the first working plate 21 is adjusted by the lifting component 40 according to the height of the soil ridge burying the grapevine, so that the soil cleaning brush turntable 22 is close to the height position of the grapevine in the soil ridge; during the movement of the walking frame 10, the drive component 30 is started to make the soil cleaning brush turntable 22 and the soil cleaning scraper turntable 23 rotate. During the movement of the walking frame 10, the soil cleaning scraper turntable 23 first scrapes away the soil above the grapevine, and then the soil cleaning brush turntable 22 sweeps away the loose soil on the surface of the grapevine during the movement.

[0025] Using the above-mentioned device has at least the following technical effects: the entire cleaning process only requires the walking frame 10 to travel along the soil ridge once in one direction, which can expose the grapevines from the soil ridge, which is conducive to the subsequent grapevine straightening and cleaning operations, greatly improving the efficiency of the early soil cleaning operation of the grapevines, and is less likely to cause hard damage to the new buds on the grapevines during the soil cleaning process, thus improving the survival rate of the grapevines.

[0026] As one of the preferred solutions in this embodiment, wherein:

[0027] The lifting assembly 40 includes a second working plate 41 and an adjusting screw 42. The second working plate 41 is horizontally arranged on the frame of the traveling frame 10, and the first working plate 21 is located directly below the second working plate 41. The adjusting screw 42 passes vertically downward along the direction of gravity through the second working plate 41 and is connected to the first working plate 21.

[0028] Specifically, in this embodiment, there are at least two adjusting screws 42. The second working plate 41 and the first working plate 21 each have through holes for the adjusting screws 42 to pass through. Threads are machined into the through holes to accommodate the adjusting screws 42, or adjusting nuts 421 are provided on one side of the through holes. This allows the adjusting screws 42 to rotate in different directions, thereby raising or lowering the first working plate 21. The two adjusting screws 42 ensure that the first working plate 21 does not rotate during its movement along the height direction, allowing the cleaning brush turntable 22 and the cleaning scraper turntable 23 to operate stably along the predetermined cleaning direction.

[0029] Furthermore, the drive assembly 30 includes a motor 31, a main drive wheel 32, and at least two transmission wheels 33, wherein the two transmission wheels 33 are respectively connected to the soil cleaning brush turntable 22 and the soil cleaning scraper turntable 23 via a transmission shaft 331; the main drive wheel 32 is connected to the drive shaft of the motor 31, and the main drive wheel 32 is synchronously connected to the two transmission wheels 33 via a transmission belt 34.

[0030] Specifically, the first working plate 21 is provided with bearings for cooperating with the rotation of the aforementioned transmission shaft 331. The transmission shaft 331 is respectively inserted into the bearings, and the two transmission wheels 33 and the soil cleaning brush turntable 22 or soil cleaning scraper turntable 23 are respectively provided at the upper and lower ends of the transmission shaft 331. The motor 31 is located between the two transmission wheels 33, and one end of the motor 31 is connected to either the first working plate 21 or the second working plate 41, so that the drive shaft of the motor 31 is connected to the main drive wheel 32 facing upward or downward. When the drive shaft of the motor 31 drives the main drive wheel 32 to rotate, it synchronously drives the soil cleaning brush turntable 22 and the soil cleaning scraper turntable 23 to rotate through the transmission belt 34. By reducing at least one motor 31 used for driving, the aforementioned rotary grapevine soil cleaning device can have a stable soil cleaning frequency while saving power consumption costs.

[0031] Furthermore, a plurality of scraping blades 231 are axially arranged on the lower side of the soil-clearing scraper turntable 23 around the drive shaft 331. The widths of the scraping blades 231 are unequal, and the widths of adjacent scraping blades 231 increase sequentially along the rotation direction of the soil-clearing scraper turntable 23. During the rotation of the soil-clearing scraper turntable 23, the scraping blades 231 with increasing widths break up the soil ridges layer by layer, effectively preventing the compacted soil clogging the scraping blades 231 and improving the soil-breaking efficiency.

[0032] Furthermore, a plurality of brush heads 221 are axially arranged around the drive shaft 331 on the lower side of the soil-cleaning brush turntable 22. The bristle lengths of the brush heads 221 are unequal, and the bristle lengths of adjacent brush heads 221 increase sequentially along the rotation direction of the soil-cleaning brush turntable 22. During the rotation of the soil-cleaning brush turntable 22, the brush heads 221 of unequal lengths can increase the contact area between the bristles and the grapevines, cleaning the loose soil above the grapevines, on the sides of the branches, and in the gaps between the branches, thereby improving the cleaning effect on the grapevines.

[0033] Furthermore, a chute 11 is provided on one side of the frame of the traveling frame 10 along a travel path perpendicular to the traveling frame 10. The second working plate 41 is slidably connected to the chute 11 by sliding components such as slide rails or pulleys provided on its side. The second working plate 41 is connected to the frame by an automatic drive device, such as an automatic telescopic cylinder. When the second working plate 41 encounters an obstacle during the movement of the traveling frame 10, the second working plate 41 can slide along the chute 11 to the inside of the traveling frame 10, while simultaneously driving the first working plate 21 located below to move towards the inside of the traveling frame 10, avoiding the obstacle and preventing the rotating soil cleaning component 20 from hitting the obstacle.

[0034] Specifically, a first obstacle avoidance controller 12 and a second obstacle avoidance controller 13 are respectively installed at the rear end of one side of the walking frame 10 and the front end of the second working plate 41 (or at the front end of one side of the walking frame 10). An obstacle avoidance driver 14 is installed on one side of the frame of the walking frame 10. The two obstacle avoidance controllers are preferably ultrasonic proximity switches, and the obstacle avoidance driver 14 is preferably an electric telescopic cylinder. The fixed end of the electric telescopic cylinder is fixed to one side of the frame of the walking frame 10, and the telescopic moving end is connected to one side of the second working plate 41. The ultrasonic proximity switch and the electric telescopic cylinder form a control circuit. When the ultrasonic proximity switch is located at the front end of the walking frame 10, the obstacle avoidance controller 12 and the obstacle avoidance driver 13 are respectively installed. When the switch senses an obstacle on the working path of the first working plate 21, such as a grape trellis or rocks, it can control the electric telescopic cylinder via an electrical signal to drive the second working plate 41 to move along the slide 11 toward the inside of the walking frame 10, thereby causing the first working plate 21 to change position and pass over the obstacle. After the sensing end of the ultrasonic proximity switch at the rear end senses the obstacle that is about to be passed, it controls the electric telescopic cylinder via an electrical signal to drive the second working plate 41 back to the working position, so that the soil cleaning brush turntable 22 and the soil cleaning scraper turntable 23 on the first working plate 21 can continue to clean the soil.

[0035] In another embodiment, the difference from the above embodiment is that:

[0036] Preferably, one end of the motor 31 is fixed to the lower side of the second working plate 41, and the drive shaft of the motor 31 is specially machined into a spline shaft 311 by a lathe. The main drive wheel 32 is rotatably connected to the first working plate 21 through a bearing, and a spline sleeve 321 is provided on the inner side of the inner ring of the bearing. The spline shaft 311 and the spline sleeve 321 are slidably and transmissionally connected. The spline shaft 311 drives the spline sleeve 321 to make the main drive wheel 32 rotate.

[0037] Specifically, in this embodiment, only one adjusting screw 42 is needed to adjust the first working plate 21, while the spline shaft 311 passing through the spline sleeve 321 can be used to replace the other adjusting screw 42, playing a guiding role in the movement of the first working plate 21 in the height direction. Based on this, when adjusting the working height of the first working plate 21 by rotating the adjusting screw 42, the spline shaft 311 of the motor 31 can move up and down along the axial direction of the spline sleeve 321, avoiding motion interference to the main drive wheel 32.

[0038] This application also discloses a soil clearing machine, which includes the rotary grapevine soil clearing device in the above embodiment and a towing drive device 50. By selecting equipment such as a tractor as the towing drive device 50, the rotary grapevine soil clearing device is connected to the tractor through detachable connectors such as locks, so as to drive the rotary grapevine soil clearing device to perform soil clearing operations, which can save manpower and improve soil clearing efficiency.

[0039] The above implementation methods achieve at least the following technical effects:

[0040] The height of the first working plate 21 can be adjusted by the lifting component 40, which facilitates the adjustment of the cleaning depth and soil breaking depth of the above-mentioned rotary grapevine soil cleaning device to adapt to soil ridges of different heights. During the movement, the soil cleaning scraper turntable 23 first scrapes away the soil above the grapevines, and then the soil cleaning brush turntable 22 sweeps away the loose soil on the surface of the grapevines during the forward movement. The entire cleaning process only requires the traveling frame 10 to travel along the soil ridge once in one direction, which can expose the grapevines from the soil ridge. This not only improves the efficiency of the early soil cleaning operation of the grapevines, but also makes it less likely to cause hard damage to the new buds on the grapevines during the soil cleaning process, thereby improving the survival rate of the grapevines.

[0041] Obviously, the above embodiments of this application are merely examples for clearly illustrating this application, and are not intended to limit the implementation of this application. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
