Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a punching device for tomato transplanting. Background Technology

[0002] Before transplanting tomatoes, it is necessary to pre-drill holes in the ground, that is, dig a small hole of appropriate size and depth in the ground, and then put the tomato seedlings in the tray into the pre-drilled hole.

[0003] The traditional method is to use a hoe or make holes by hand. However, the aforementioned methods are time-consuming and labor-intensive, requiring the completion of 3 to 5 acres of drilling work per day. This is labor-intensive, and the drilling is not standardized. The size, depth, and shape of the holes are not uniform, making it difficult to meet the prescribed transplanting requirements. This is especially true when the transplanting scale is large, as it is difficult to complete high-quality drilling work in a short period of time. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a punching device for tomato transplanting, which addresses the shortcomings of the prior art. This punching device has a simple structure, is easy to use, realizes continuous mobile punching, and produces holes of consistent size, depth and shape with precise punching spacing. It does not scratch the film, saves manpower, and has high punching efficiency. The punching device with 1 film and 2 rows can complete punching work on 100-120 acres per day, and the punching device with 3 film and 6 rows can complete punching work on 330 acres per day. It is easy to install and recycle and can be widely applied.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a punching device for transplanting tomatoes, characterized in that it includes a frame connected to the rear end of a tractor, a drive shaft is rotatably mounted on the frame, and three sets of mounting sleeves are rotatably mounted on the drive shaft through bearings. Each set of mounting sleeves includes two mounting sleeves, and each set of mounting sleeves is provided with a connecting rod for reinforcement on both sides. One end of the connecting rod is fixedly connected to the frame, and the other end of the connecting rod is rotatably connected to the drive shaft.

[0006] A drilling wheel is fixedly installed on the mounting sleeve. Eight mounting cylinders are evenly fixedly installed around the circumference of the drilling wheel. A rotating shaft is rotatably installed inside the mounting cylinder via a bearing. A drilling bit is fixedly connected to one end of the rotating shaft outside the drilling wheel. A first bevel gear is fixedly installed on one end of the rotating shaft inside the drilling wheel. A second bevel gear is fixedly installed on the transmission shaft. All of the first bevel gears mesh with the second bevel gear.

[0007] The rotation of the drive shaft can be driven by the cooperation of the first bevel gear and the second bevel gear, which in turn drives the rotating shaft to rotate, making the drilling process smoother.

[0008] As the frame moves at low speed with the tractor, the drilling bit is inserted into the top of the ridge to make holes. At the same time, under the friction between the drilling wheel and the plastic film on the ridge, the drilling wheel rotates, and the drilling bit also rotates around the drive shaft, thus making equally spaced transplanting holes on the top of the ridge.

[0009] Preferably, a gearbox is fixedly mounted on the frame, the input end of the gearbox is connected to the power output shaft of the tractor, a first sprocket is fixedly mounted on the output end of the gearbox, and a second sprocket is fixedly mounted on the drive shaft, with the first sprocket and the second sprocket being connected in a driving connection.

[0010] The power output shaft of the tractor provides power to the drive shaft, which in turn drives the drill bit to rotate, making the drilling process easier and faster.

[0011] Preferably, the top of the frame is hinged to the rear end of the tractor, and the side end of the frame is hinged to the output shaft of the tractor's hydraulic system, the output shaft of the tractor's hydraulic system being used to drive the frame to rotate and lift.

[0012] The extension and retraction of the output shaft of the tractor's hydraulic system can push the frame to rotate up or down, thereby controlling the lifting and lowering of the frame. When drilling is not required, the frame can be raised.

[0013] This utility model has the following advantages compared with the prior art: This invention features a drilling wheel mounted on a drive shaft via a bearing. A rotating shaft is mounted on the circumference of the drilling wheel via a mounting cylinder. A drilling bit is fixedly mounted on the outer end of the rotating shaft. The tractor drives the frame to move, which in turn drives the drilling wheel to rotate. The drilling bit drills holes of uniform size at equal intervals on the ridge top. At the same time, the drive shaft can also drive the drilling bit to rotate through the cooperation of bevel gears. This reduces the obstruction caused by the friction between the soil and the drill bit during continuous drilling, making the drilling process easier and smoother, and facilitating continuous drilling.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0019] Explanation of reference numerals in the attached figures: Detailed Implementation

[0020] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0022] like Figures 1-4 As shown, this utility model provides a perforation device for tomato transplanting, which is a 3-film, 6-row perforation device that can complete perforation work on 330 mu (approximately 22 hectares) per day. It includes a frame 1 connected to the rear end of a tractor. A drive shaft 2 is rotatably mounted on the frame 1. Three sets of mounting sleeves 3 are rotatably mounted on the drive shaft 2 via bearings. Each set of mounting sleeves 3 includes two mounting sleeves 3. Each set of mounting sleeves 3 has connecting rods 13 on both sides for reinforcement. One end of each connecting rod 13 is fixedly connected to the frame 1, and the other end is rotatably connected to the drive shaft 2. Each set of mounting sleeves 3 completes the perforation work of 1 film, 2 rows, that is, perforating 2 rows of transplanting holes on one strip of mulch film laid on each ridge.

[0023] A drilling wheel 4 is fixedly installed on the mounting sleeve 3. Eight mounting cylinders 5 are evenly fixedly installed around the drilling wheel 4. A rotating shaft 6 is rotatably installed inside the mounting cylinder 5 via bearings. A drilling bit 7 is fixedly connected to one end of the rotating shaft 6 outside the drilling wheel 4. A first bevel gear 8 is fixedly installed on one end of the rotating shaft 6 inside the drilling wheel 4. A second bevel gear 9 is fixedly installed on the transmission shaft 2. All of the first bevel gears 8 mesh with the second bevel gear 9.

[0024] The rotation of the drive shaft 2 can drive the rotating shaft 6 to rotate through the cooperation of the first bevel gear 8 and the second bevel gear 9. The drilling bit 7 on the rotating shaft 6 rotates, making the drilling process smoother.

[0025] When the frame 1 moves at low speed with the tractor, the drilling bit 7 is inserted into the top of the ridge to make holes. At the same time, under the action of friction between the drilling wheel 4 and the mulch film on the top of the ridge, the drilling wheel 4 rotates, and the drilling bit 7 also rotates around the drive shaft 2, thereby making transplanting holes at equal intervals on the top of the ridge.

[0026] In this embodiment, a reduction gearbox 10 is fixedly installed on the frame 1. The input end of the reduction gearbox 10 is connected to the power output shaft of the tractor. A first sprocket 11 is fixedly installed on the output end of the reduction gearbox 10. A second sprocket 12 is fixedly installed on the drive shaft 2. The first sprocket 11 and the second sprocket 12 are connected in a driving connection.

[0027] The power output shaft of the tractor provides power to the drive shaft 2, which in turn drives the drill bit 7 to rotate, making the drilling process easier and faster.

[0028] In this embodiment, the top end of the frame 1 is hinged to the rear end of the tractor, and the side end of the frame 1 is hinged to the output shaft of the tractor's hydraulic system. The output shaft of the tractor's hydraulic system is used to drive the frame 1 to rotate and lift.

[0029] The output shaft of the tractor's hydraulic system can extend and retract, which can push the frame 1 to rotate up or down, thereby realizing the lifting and lowering control of the frame 1. When drilling is not required, the frame 1 can be lifted.

[0030] When in use, the distance between two adjacent sets of mounting sleeves 3 is the row spacing, and two rows of tomatoes are transplanted per row. When the device is moved and punched by a tractor, punching can be completed on three rows simultaneously.

[0031] The tractor pulls the frame 1 at low speed. When drilling is required, the tractor's hydraulic system is activated. The output shaft of the tractor's hydraulic system retracts, which pushes the frame 1 to rotate downward, so that the drilling wheel 4 is in close contact with the plastic film on the top of the ridge. The drilling drill bit 7 can be inserted into the top of the ridge, drill through the plastic film, and realize the drilling of the plastic film and the ridge.

[0032] When the frame 1 moves at low speed with the tractor, the drilling bit 7 is inserted into the top of the ridge to make holes. At the same time, under the friction between the drilling wheel 4 and the top of the ridge, the drilling wheel 4 rotates, and the drilling bit 7 also rotates around the drive shaft 2, thereby making transplanting holes at equal intervals on the top of the ridge.

[0033] The tractor's power take-off shaft provides power to the drive shaft 2. The rotation of the drive shaft 2 can drive the rotating shaft 6 to rotate through the cooperation of the first bevel gear 8 and the second bevel gear 9. The drilling bit 7 on the rotating shaft 6 rotates, making the drilling process smoother.

[0034] After drilling is completed, the tractor's hydraulic system is activated. The output shaft of the tractor's hydraulic system extends, which can push the frame 1 to rotate upward, moving the drilling wheel 4 and the drilling bit 7 away from the top of the ridge.

[0035] As the drilling bit 7 rotates with the drilling wheel 4 during drilling, it is inserted into the top of the ridge at an angle and then leaves the top of the ridge symmetrically at the same angle. Therefore, the transplanting hole made by the drilling bit 7 on the top of the ridge does not completely fit the shape of the drilling bit 7. The volume of the hole is larger than the volume of the drilling bit 7, and the top surface of the hole is not circular, but close to elliptical.

[0036] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any simple modifications, alterations, and equivalent changes made to the above embodiments based on the technical essence of this utility model shall still fall within the protection scope of this utility model.
