DETAILED DESCRIPTION

[0024] The following will be combined with specific embodiments and attached Figure 1-6 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the embodiments described are only some preferred embodiments of the present invention, not all embodiments. Those skilled in the art may make similar modifications without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] The utility model provides a ditching and soil covering mechanism for a garlic planter (such as Figure 1As shown), it includes a bearing bracket 1 and three groups of trenching and covering components 2. The bearing bracket 1 is used to realize the installation support of the three groups of trenching and covering components 2. The bearing bracket 1 is made of steel pipes and steel plates by welding. The three groups of trenching and covering components 2 are arranged on the bearing bracket 1 at equal intervals along the left and right directions of the bearing bracket 1. In actual application, there is a garlic sowing ridge 5 between the two groups of trenching and covering components 2. Therefore, the distance between the two adjacent groups of trenching and covering components 2 can be determined according to the width of the actual garlic sowing belt ridge 5. Each group of trenching and covering components 2 includes a swinging drive mechanism, a swinging bracket 22, a trenching drive mechanism, a transmission mechanism, a trenching component 25, and a covering deflector 26. The swinging bracket 22 is hinged to the rear end of the bearing bracket 1. Specifically, a first hinged seat 11 is provided at the rear end of the bearing bracket 1, and the upper front end of the swinging bracket 22 is connected to the first hinged seat 11. An articulated seat 11 is hingedly connected by a pin shaft. The swing drive mechanism can realize the up and down swing drive and positioning of the corresponding swing bracket 22. The ditching drive mechanism is arranged on the swing bracket 22. The ditching drive mechanism realizes the driving of the ditching assembly through the transmission mechanism. When the swing drive mechanism is used to realize the up and down swing of the swing bracket 22, the up and down swing of the ditching assembly 25 is realized synchronously, and then the ditching depth is regulated. Two groups of symmetrically distributed ditching assemblies 25 are arranged on both sides of the rear end of the transmission mechanism. Each group of ditching assemblies 25 includes several rotary tillage blades 251. When the two groups of ditching assemblies 25 work synchronously, the soil is thrown, thereby realizing the formation of the ridge 4. The soil covering deflector 26 is used to throw the soil thrown up by the corresponding rotary tillage blade 251 onto the corresponding garlic sowing ridge 5. During the actual working process, the trenching component continues to move in the leveled soil where garlic has been planted. As the rotary tiller 251 rotates at a high speed, the soil in the corresponding area is thrown away. The soil is thrown away to form a ridge 4, and garlic planting ridges 5 are formed on both sides of the ridge 4. The thrown soil is blocked and reflected by the covering deflector 26 and falls directly onto the upper part of the garlic planting ridge 5, thereby realizing the covering operation. In actual application, the high-speed rotating rotary tiller 251 throws the soil in the direction of the trenching and covering mechanism.

[0026] On the basis of the above embodiment, the specific implementation of the transmission mechanism is as follows: the transmission mechanism includes a hydraulic motor 23, a gearbox 24, and an angle fine-tuning mechanism 27. The front end of the gearbox 24 is hingedly connected to the swing bracket 22. The hydraulic motor 23 adopts a chain drive method to realize the power input of the gearbox 24. Specifically, the hydraulic motor 23 is arranged on the swing bracket 22, and a front drive shaft 241 is provided at the front end of the gearbox 24. The axis of the front drive shaft 241 is coaxially distributed with the axis of rotation of the gearbox 24 around the swing bracket 22. A sprocket is provided on the output shaft 231 of the hydraulic motor 23, and a sprocket is provided at the end of the front drive shaft 241. A transmission chain 232 is sleeved on the corresponding two chain wheels. On the wheel, when the hydraulic motor 23 is started, the rotation of the front drive shaft 241 is realized. A rear drive shaft 242 is set at the rear end of the gearbox 24. The rotation of the front drive shaft 241 is directly realized by the transmission relationship set inside the gearbox 24 to realize the rotation drive of the rear drive shaft 242. The gearbox 24 is a commonly used technical product in this technical field. In this specific embodiment, the gearbox 24 can be selected from the gearbox disclosed in the Chinese utility model patent (publication number: CN103238385A) for the chain drive gearbox of a rotary tiller. The angle fine-tuning mechanism 27 is provided on the swing bracket 22, and the angle fine-tuning mechanism 27 can realize the adjustment and positioning of the placement angle of the gearbox 24 relative to the swing bracket 22;Specifically, the angle fine-tuning mechanism 27 includes a square guide tube 271, a square telescopic rod 272, and an adjusting threaded rod 273. The middle portion of the square guide tube 271 is hingedly connected to the rear end of the swing bracket 22, that is, a second hinge seat 221 is provided at the front portion of the swing bracket 22, and a supporting shaft is provided on both side walls of the square guide tube 271. The supporting shaft is rotatably provided on the second hinge seat 221 to realize the hinged installation of the square guide tube 271. The lower portion of the square telescopic rod 272 is hingedly connected to the rear end of the swing bracket 22. The end is hingedly connected to the upper rear end of the gearbox 24, that is, a fourth hinge seat 243 is provided at the upper rear end of the gearbox 24, and the lower part of the square telescopic rod 272 is hingedly connected to the fourth hinge seat 243 through a pin shaft. The upper end of the square telescopic rod 272 is sleeved in the square guide tube 271, and the adjusting threaded rod 273 rotating wheel is provided in the upper part of the square guide tube 271, and the adjusting threaded rod 273 can only rotate in the square guide tube 271 and cannot move up and down. The arrangement in which the adjusting threaded rod 273 rotates within the square guide tube 271 but cannot move up and down is a common technical means in the mechanical field. The specific connection method between the adjusting threaded rod 373 and the square guide tube 271 will not be described in detail. The lower end of the adjusting threaded rod 273 is connected to the upper portion of the square telescopic rod 272 by threaded engagement. That is, a threaded hole is provided on the upper portion of the square telescopic rod 272 to engage with the lower portion of the adjusting threaded rod 273. The lower portion of the adjusting threaded rod 273 is sleeved into the threaded hole. Rotating the adjusting threaded rod 273 enables the square telescopic rod 272 to telescope within the square guide tube 1. The square telescopic rod 272 can move up and down, thereby driving the rear end of the gearbox 24 to adjust the placement angle relative to the swing bracket 22. In actual application, the swing drive mechanism and the angle fine-tuning mechanism 27 can be used to adjust the placement angle of the ditching assembly 25, generally achieving the excavation of a ditch 4 of appropriate depth.

[0027] Furthermore, after the square telescopic rod 272 is used to adjust the angle of the gearbox 24, in order to facilitate the positioning of the square telescopic rod 272 in the square guide tube 271, a pressing bolt 275 is provided on the side wall of the square guide tube 271 for pressing and fixing the square telescopic rod 272. When adjusting the position of the square telescopic rod 272, the pressing bolt 275 is loosened. After the adjustment, the pressing bolt 275 is tightened. In order to further improve the rotation convenience of the adjusting threaded rod 273 and thus improve the angle adjustment efficiency of the gearbox 24, a crank 276 is provided on the upper part of the adjusting threaded rod 273. The crank 276 can be used to increase the rotation speed of the adjusting threaded rod 273.

[0028] On the basis of the above embodiment, the specific installation implementation method of the rotary tiller 251 on the rear drive shaft 242 of the gearbox 24 is as follows: the rear drive shaft 242 passes through the box body of the gearbox 24 on the left and right sides, and a blade mounting seat 252 is provided at both ends of the left and right ends of the rear drive shaft 24, and each of the blade mounting seats 252 is provided with a plurality of blade mounting openings, and each of the blade mounting openings corresponds to the installation of a rotary tiller 251. In actual application, four blade mounting openings are provided on each blade mounting seat 252, and the four blade mounting openings are evenly spaced along the circumferential direction of the rear drive shaft 242. Figure 3 In the figure, the entire furrowing mechanism moves to the right, and the rotary tiller 251 rotates counterclockwise, thereby throwing the soil toward the soil covering shroud 26 on the right side.

[0029] On the basis of the above embodiment, the specific installation implementation of the soil covering guide hood 26 is as follows: a support plate 274 is fixedly provided at the upper position of the lower end of the square telescopic rod 272, and the soil covering guide hood 26 is provided on the support plate 274. The soil covering guide hood 26 realizes shielding above, above the front, and above the rear of the corresponding two groups of furrowing components. In actual application, the high-speed rotating rotary blade 251 will throw the soil obliquely forward away from the side wall of the gearbox 24. The obliquely thrown soil is blocked by the soil covering guide groove 26 and flows back, thereby finally achieving the coverage of the soil to the upper part of the garlic sowing ridge 5. The movement trajectory of the furrowing component to realize the soil throwing is as follows: Figure 4 shown.

[0030] Based on the above embodiment, the swing drive mechanism is specifically implemented as follows: the swing drive mechanism includes a hydraulic cylinder 21, the fixed end of the hydraulic cylinder 21 being hingedly connected to the support frame 1, and the telescopic end of the hydraulic cylinder 21 being hingedly connected to the upper portion of the corresponding swing frame 22. Specifically, an articulated seat is provided on the support frame 1, which is hingedly connected to the fixed end of the hydraulic cylinder 21. The hinged connection between the articulated seat and the fixed end of the hydraulic cylinder 21 is achieved by a pin. A third articulated frame 222 is provided on the upper portion of the swing frame 22, and the telescopic end of the hydraulic cylinder 21 is articulatedly connected to the third articulated frame 222 by a pin. The telescopic movement of the hydraulic cylinder 21 enables the vertical adjustment of the swing frame 22, and the pressure-maintaining function of the hydraulic cylinder 21 enables the positioning of the swing frame 22. In actual application, the three hydraulic cylinders 21 can be independently telescopically adjusted, and the three hydraulic motors 23 can be independently driven to rotate, thereby enabling the trenching and covering operation of each set of trenching and covering mechanisms to be controlled according to actual trenching and covering requirements.

[0031] On the basis of the above embodiment, after the trenching and covering operation is completed by using the trenching and covering mechanism, in order to improve the flatness of the film covering of the garlic planting ridge 5, the trenching and covering mechanism is further provided with a leveling mechanism, wherein the leveling mechanism comprises a leveling rod 31 and an inclined mounting groove 32, the rear and upper parts of the inclined mounting groove 32 are in an open state, and an inclined mounting groove 32 is provided between two adjacent swing brackets 22, the inclined mounting groove 32 is fixedly connected to the bearing bracket 1 and the inclined mounting groove 32 is in a front high state. In the rear low state, two connecting rods 33 corresponding to the two inclined mounting grooves 32 are provided on the leveling rod 31, and the rear ends of the connecting rods 33 are hingedly set in the corresponding inclined mounting grooves 32. The leveling rods 31 are distributed along the direction in which the three groups of trenching and covering components are distributed in sequence and the leveling rods are located behind the three groups of trenching and covering components. When trenching and covering operations are carried out, the leveling rods 31 are swung downward and placed on the ground. When trenching and covering operations are no longer carried out, the leveling rods 31 are swung upward and retracted.

[0032] The present invention also provides a garlic planter, including a ditching and soil-covering mechanism for a garlic planter as described above, wherein the supporting bracket 1 is fixedly arranged at the rear end of the frame of the garlic planter. The garlic planter can sow two ridges of garlic in one travel process, and its operation method is to first sow two ridges of garlic in the process of its travel, and then use the ditching and soil-covering mechanism at the rear end to realize the ditching and soil-covering operations of the two ridges of garlic that have been planted in the front. In order to facilitate the rationality of garlic planting, ditching and soil-covering operations in the entire garlic planting area using the garlic planter (that is, there is no repeated ditching and repeated soil-covering on the garlic planting ridges), during one travel process of the garlic planter, the middle group of ditching and soil-covering components and the group of ditching and soil-covering components on the left or right side are made to work synchronously as needed. Specifically, if Figure 5 As shown, the middle group of trenching and covering components and the group of trenching and covering components located on the right side thereof are in a trenching and covering state formed after synchronous operation. The formed covering area 7 is distributed over the entire upper part of the garlic planting ridge 5 between the two groups of trenching and covering components and the upper half of the garlic planting ridge 5 located outside the working trenching and covering components. When the one-time travel operation process is completed, a 180-degree U-turn is performed. After the U-turn, the middle group of trenching and covering components and the left group of trenching and covering components are operated synchronously. During this travel process, the left group of trenching and covering components can just realize the covering operation of the other half area of ​​the garlic sowing ridge 5 that was half covered in the previous travel process, thereby realizing the continuous covering operation of the garlic sowing belt 5.

[0033] In the present invention, “left” and “right” are relative positions used for the convenience of describing positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.

[0034] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

However, the present invention is not limited to the above embodiments and examples. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the concept of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
