Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a roller-type punch. Background Technology

[0002] Existing seedling hole drills typically use manual drilling techniques, such as CN223094194U "A Drilling Tool". However, when the area of ​​farmland requiring seedling hole drilling is large, manual drilling is labor-intensive. Therefore, other methods are used instead. Figure 1 The roller-type punch shown is used for mechanical operations. The existing roller-type punch includes a roller body and a punching tube welded to the circumference of the roller body. A drive shaft is fixedly connected to the center of the roller body. This drive shaft is used to drive the roller body to roll on the ground by connecting to a work vehicle.

[0003] However, the punching tubes of these roller-type punchers are all welded to the circumference of the roller body, which means that the spacing of the planting holes drilled by the roller-type puncher is not adjustable. A single machine can only adapt to the planting needs of a single plant spacing. When it is necessary to plant crops with different plant spacing, such as wheat and corn, the entire roller-type puncher must be replaced to suit different planting needs. Thus, when using this roller-type puncher, operators need to keep multiple sizes of roller spare parts to suit different crop planting needs, which is costly. Moreover, if the equipment needs to be replaced during operation, the workload is large and time-consuming, which will lead to a decrease in production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a roller-type hole punch, which is mainly used to drill planting holes, so as to achieve the purpose of adjustable planting hole spacing without replacing the entire roller-type hole punch, and is suitable for different crop planting requirements.

[0005] The present invention discloses a roller-type punch, comprising a roller body, a plurality of punching tubes provided on the roller body, and a drive shaft fixedly provided on the roller body for transmission connection with a work vehicle.

[0006] The roller body includes a hollow first cylinder and a second cylinder. The first cylinder and the second cylinder are coaxially and parallel, and there is a gap between the first cylinder and the second cylinder to form a soil discharge space. The first cylinder and the second cylinder are provided with equally spaced mounting holes, and the mounting holes on both sides of the soil discharge space are arranged in parallel. The first cylinder is also provided with a support mechanism for supporting the first cylinder. The drive shaft is concentric with the first cylinder and fixed on the support mechanism.

[0007] The perforated pipe includes a connecting steel plate and a perforated conical pipe. The bottom of the perforated conical pipe is fixed on the connecting steel plate. The connecting steel plate has a through hole that communicates with the bottom of the perforated conical pipe. The through hole is corresponding to the soil discharge space. The connecting steel plate has connecting holes on both sides of the through hole that are adapted to the mounting holes. The spacing between adjacent connecting holes is the same as the spacing between adjacent mounting holes. The connecting steel plate also has connecting bolts that pass through the connecting holes and mounting holes in sequence to connect the perforated pipe to the first cylinder and the second cylinder.

[0008] Furthermore, the soil discharge space is strip-shaped and its width is greater than the diameter of the through hole.

[0009] As a preferred embodiment, the soil discharge through hole is provided with staggered protrusions at intervals.

[0010] As a preferred embodiment, the protrusion is triangular or rectangular.

[0011] Furthermore, the support mechanism includes support rods, which are arranged radially and interlaced on the same plane with the transmission shaft as the center, and the other end of the support rods is fixedly connected to the inner side of the first cylinder.

[0012] Furthermore, the diameter of the end of the perforated tapered tube that connects to the roller body is larger than the diameter of the end of the perforated tapered tube that is away from the roller body; the end of the perforated tapered tube that is away from the roller body is also provided with a serrated portion extending away from the roller body.

[0013] Furthermore, the second cylinder is equipped with multiple vertically arranged reinforcing plates.

[0014] Furthermore, the diameter of the mounting hole is 6-8 mm, and the spacing between adjacent mounting holes is 10 mm.

[0015] Furthermore, the diameters of the first cylinder and the second cylinder are 46 mm.

[0016] The beneficial effects of this utility model are as follows: This roller-type hole punch, by setting up a first cylinder and a second cylinder that are hollow inside and coaxially parallel, forms a soil discharge space between the two for easy soil discharge. A support mechanism is set in the first cylinder to ensure the stability of the equipment composed of the first cylinder, the second cylinder and the hole punching tube, and to avoid deformation during use. The drive shaft is designed to be coaxial with the roller and fixedly connected to the support mechanism, ensuring uniform force distribution when the work vehicle is driven, and avoiding eccentric vibration. By setting a connecting steel plate at the bottom of the hole punching cone tube, and opening a connecting hole on the connecting steel plate, the hole punching tube can be detachably set on the roller body by connecting bolts passing through the connecting hole and the mounting hole in sequence, so as to adjust the installation position of the hole punching tube according to the spacing requirements of the planting holes to be drilled. With this design, the operator only needs to disassemble and change the position of the hole punching tube to achieve the purpose of drilling the planting hole spacing, without replacing the entire roller-type hole punch, and can achieve adjustable planting hole spacing, which is suitable for different crop planting requirements.

Detailed Implementation

[0020] The present invention will be further described below.

[0021] This utility model provides a roller-type hole drill, mainly used for drilling planting holes. It includes a roller body 1 with multiple drilling tubes 2. A drive shaft 4, connected to a work vehicle, is fixedly mounted on the roller body 1. The roller body 1 includes a hollow first cylinder 11 and a hollow second cylinder 12. The first cylinder 11 and the second cylinder 12 are coaxially parallel and spaced apart to form a soil discharge space 13. The first cylinder 11 and the second cylinder 12 have equidistantly arranged mounting holes 14, with the mounting holes 14 on both sides of the soil discharge space 13 arranged in parallel. A support mechanism 111 for supporting the first cylinder 11 is also provided inside the first cylinder 11. The drive shaft... 4. The perforated tube 2 is co-centered with the first cylinder 11 and fixed on the support mechanism 111; the perforated tube 2 includes a connecting steel plate 22 and a perforated cone tube 21. The bottom of the perforated cone tube 21 is fixed on the connecting steel plate 22. The connecting steel plate 22 has a through hole 221 that communicates with the bottom of the perforated cone tube 21. The through hole 221 is correspondingly set with the soil discharge space 13. The connecting steel plate 22 has connecting holes 222 located on both sides of the through hole 221 and adapted to the mounting hole 14. The distance between adjacent connecting holes 222 is the same as the distance between adjacent mounting holes 14. The connecting steel plate 22 also has connecting bolts 3 that pass through the connecting holes 222 and the mounting holes 14 in sequence to connect the perforated tube 2 with the first cylinder 11 and the second cylinder 12.

[0022] like Figures 1-2As shown, the roller-type hole punch includes a roller body 1, on which multiple punching tubes 2 are provided. The number of punching tubes 2 is set according to the circumference of the roller body 1 and the spacing of the planting holes. A drive shaft 4, which is connected to the working vehicle, is fixed at the center of the roller body 1. The drive shaft 4 is connected to the working vehicle so that the roller body 1 can be rotated by the forward and backward movement of the working vehicle, thereby enabling the roller-type hole punch to mechanically drill planting holes. The roller body 1 includes a hollow first cylinder 11 and a second cylinder 12. The first cylinder 11 and the second cylinder 12 are coaxially and parallel to each other, and are connected by two independently set first cylinders 11 and second cylinders 12. Steel sheets 22 are used to form the entire roller body 1, ensuring both the ease of disassembly and the integrity of the roller body 1. A gap is provided between the first and second roller bodies to form a soil discharge space 13, allowing soil drilled by the perforating pipes 2 installed on the first and second roller bodies 11 to be discharged through the soil discharge space 13 for drilling the next planting hole. To ensure the stability of the roller body 1 during use, a support mechanism 111 is provided inside the first roller body 11. The support mechanism 111 can be composed of staggered support plates, support rods, etc., installed inside the first roller body 11 to support it, thus reducing the burden on the roller body. While ensuring the weight of the equipment, it is also ensured that the first cylinder 11 will not deform during use; the drive shaft 4 is coaxial with the first cylinder 11 and fixedly connected to the support mechanism 111, ensuring uniform force distribution during the transmission of the work vehicle and avoiding eccentric vibration; to facilitate the detachable installation of the perforated tube 2 on the first cylinder 11 and the second cylinder 12, both the first cylinder 11 and the second cylinder 12 are provided with equally spaced mounting holes 14, which are evenly spaced around the first cylinder 11 and the second cylinder 12, so as to adjust the installation position of the perforated tube 2 according to the required spacing of the planting holes; the spacing between adjacent mounting holes 14 is controlled at 10mm to facilitate application. The drilling tube 2 is adjusted to meet the requirements of various planting hole spacings. To facilitate the adjustment of the installation position of the drilling tube 2, the drilling tube 2 includes a connecting steel plate 22 and a drilling cone tube 21. The connecting steel plate 22 can be a rectangular steel plate or an ear plate welded to the bottom of the drilling cone tube 21. The connecting steel plate is provided with a through hole 221 that communicates with the drilling cone tube 21. The through hole 221 is connected to the soil discharge space 13 so that when the drilling cone tube 21 drills the planting hole, the columnar soil cut in the drilling cone tube 21 falls through the through hole 221 on the connecting steel plate 22 and the soil discharge space 13 by gravity during the rotation of the roller body 1, so as to facilitate the drilling of the next planting hole.To facilitate the connection of the perforated tube 2 with the first cylinder 11 and the second cylinder 12 to form an integral structure, connecting holes 222 are provided on the connecting steel plate 22, located on both sides of the through hole 221 and adapted to the mounting hole 14. The connecting holes 222 are arranged on both sides of the perforated tapered tube 21 along the length of the connecting steel plate 22, and the spacing between adjacent connecting holes 222 is the same as the spacing between the mounting holes 14. Then, the perforated tube 2 is detachably mounted on the roller body 1 by passing the connecting bolts 3 through the connecting holes 222 and the mounting holes 14 in sequence, so as to adjust the installation position of the perforated tube 2 according to the spacing requirements of the planting holes to be drilled. This roller-type hole punch features a hollow, coaxially parallel first cylinder 11 and a second cylinder 12, creating a soil discharge space 13 between them for easy soil removal. A support mechanism 111 is installed inside the first cylinder 11 to ensure the stability of the device, which consists of the first cylinder 11, the second cylinder 12, and the punching tube 2, preventing deformation during use. The drive shaft 4 is coaxial with the roller 1 and fixedly connected to the support mechanism 111, ensuring uniform force distribution during vehicle transmission and preventing eccentric vibration. A connecting steel plate 22 is installed at the bottom of the punching cone tube 21, with a connecting hole 222 on the connecting steel plate 22. The punching tube 2 can be detachably mounted on the roller 1 by connecting bolts 3 passing through the connecting hole 222 and the mounting hole 14 in sequence, allowing adjustment of the installation position of the punching tube 2 according to the required spacing of the planting holes. With this design, operators only need to disassemble and change the position of the punching tube 2 to achieve the desired spacing of the planting holes, without replacing the entire roller-type hole punch, thus achieving adjustable planting hole spacing suitable for different crop planting requirements. Furthermore, the width of the soil discharge space 13 between the first cylinder 11 and the second cylinder 12, which are designed in a split configuration, can be adjusted according to the spacing of the connecting holes 222 on the connecting steel plate 22, or in other words, the size of the perforated tapered tube 21 set on the connecting steel plate 22, to accommodate the drilling requirements of planting holes of different sizes.

[0023] To ensure that the through hole 221 of the connecting steel plate 22 can always correspond to the soil discharge space 13 when the spacing of the perforated pipe 2 is adjusted according to planting needs; the soil discharge space 13 is strip-shaped and the width of the soil discharge space 13 is greater than the diameter of the through hole 221; by setting the soil discharge space 13 to be strip-shaped, there is no need to process the first cylinder 11 and the second cylinder 12. The first cylinder 11 and the second cylinder 12 can be connected to form an integral structure by using the connecting steel plate 22, which saves processing costs. When adjusting the position of the perforated pipe 2, the through hole 221 of the connecting steel plate 22 will always be partially connected to the strip-shaped soil discharge space 13 so that the soil drilled by the perforated pipe 21 can be discharged from the soil discharge space 13.

[0024] Furthermore, in order to allow the columnar soil passing through the soil discharge space 13 to be cut and broken up, and to avoid clogging the soil discharge space 13, such as... Figure 2As shown, the soil discharge space 13 is provided with staggered protrusions 131. The protrusions 131 in the soil discharge space 13 are used to cut the columnar soil drilled from the drilling cone tube 21. The protrusions 131 can be triangular or rectangular steel sheets welded to the first cylinder 11 and the second cylinder 12. The irregular soil discharge channel formed between the protrusions 131 and the through holes 221 provided on the connecting steel sheet 22 can cut the columnar soil drilled from the drilling cone tube 21 and avoid blockage of the soil discharge space 13.

[0025] To ensure the supporting effect of the support mechanism 111 on the first cylinder 11 and the stability of the entire cylinder 1, the support mechanism 111 includes a support rod 112. The support rod 112 is arranged radially on the same plane with the transmission shaft 4 as the center. The other end of the support rod 112 is fixedly connected to the inner side of the first cylinder 11. Using the support rod 112 as the support mechanism 111 can not only ensure the supporting effect on the first cylinder 11, but also make the interior of the first cylinder 11 hollow, reducing the weight of the entire cylinder 1. Furthermore, when the columnar soil drilled from the perforated cone tube 21 falls into the interior of the first cylinder 11 through the soil discharge space 13, the support rod 112 can also cut and break up the columnar soil.

[0026] To facilitate drilling by allowing the perforating cone 21 to penetrate the soil as it rotates with the roller 1, the diameter of the end of the perforating cone 21 connected to the roller 1 is larger than the diameter of the end of the perforating cone 21 away from the roller 1. The end of the perforating cone 21 away from the roller 1 is also provided with a serrated portion 211 extending away from the roller 1. The larger diameter of the end of the perforating cone 21 closer to the roller 1 enhances the connection stability between the perforating cone 21 and the connecting steel plate 22, while also increasing structural strength. The smaller diameter of the end of the perforating cone 21 away from the roller 1, coupled with the serrated portion 211, enables sharp cutting. The serrated portion 211 extends away from the roller 1 to reduce drilling resistance, making it suitable for compacted soil operations. Furthermore, during film-covered soil operations, only the areas requiring drilling need to be cut, without affecting the film installation in other areas.

[0027] To ensure the stability of the second cylinder 12 during use, such as Figure 2 As shown, the second cylinder 12 is provided with a plurality of vertically arranged reinforcing plates 121. By setting the reinforcing plates 121, the stability of the second cylinder 12 during use is enhanced, and deformation during use is avoided, which would cause deformation of the drilling spacing.

[0028] To facilitate the installation of the perforated tubes 2 on the first cylinder 11 and the second cylinder 12, and to ensure that the first cylinder 11 and the second cylinder 12 can be connected by connecting steel plates 22 to form an integral roller body 1, after multiple field tests and adjustments, the diameter of the mounting holes 14 was determined to be 6-8 mm, and the spacing between adjacent mounting holes 14 was determined to be 10 mm. Designing the diameter of the mounting holes 14 to 6-8 mm facilitates connection and installation using conventional bolts, reducing maintenance costs. Furthermore, the 10 mm spacing between adjacent mounting holes 14 supports stepless adjustment of the perforation density within the range of 10-20 holes / meter, adapting to different operational needs. As a preferred method, experimental verification shows that a diameter of 46 mm for the first cylinder 11 and the second cylinder 12 is the optimal size, ensuring both the perforation depth and the number of perforated tubes 2 installed, as well as the stability of the entire roller body 1.
