Description

Technical Field

[0001] This utility model relates to the field of drilling attachments, specifically to a drilling attachment. Background Technology

[0002] Hill sowing is an important task in agricultural production. During planting, seeds need to be sown in holes with a certain row spacing and hole spacing. Traditionally, drilling holes for crop planting is done manually using tools to insert holes in the soil. This method is inefficient, increases the labor intensity of workers, and makes it difficult to control the depth of holes, row spacing, and hole spacing. The holes are also arranged haphazardly, which is not conducive to crop sowing and seed survival. Therefore, existing technologies have developed drilling attachments that are mounted on a sliding trolley and rotated by it, and use the attachments to drill holes in the soil at equal intervals, which greatly improves the efficiency of crop sowing.

[0003] Existing drilling tools require the needle to be designed as a hollow cylinder to stably form a seedable hole as it rolls into the soil. This allows the needle to be pulled out of the soil after insertion. However, this makes the inside of the cylinder easily clogged with soil after use, making it difficult to drill holes and losing the effect of forming stable holes, thus greatly reducing the practicality of the drilling tool.

[0004] The purpose of this utility model research is to design a highly practical punching attachment that is less prone to clogging of the pins, addressing the problems existing in the prior art. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a punching attachment that can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A punching attachment, comprising:

[0008] The support frame has wheels that rotate on both the left and right sides.

[0009] A rotating component is mounted within the bracket and rotates back and forth. The rotating component has several perforated parts that are spaced apart circumferentially and extend radially outward. The inner and outer ends of the perforated parts are connected to form a perforation channel. A discharge gap that connects to the perforation channel is axially penetrating through the side wall of the perforated part. A discharge port that connects to the perforation channel is recessed on the side of the discharge gap away from the rotating component. When the perforated part is rotated by the rotating component until its outer end faces downward, its height is lower than the bottom of the traveling wheel. Both the discharge gap and the discharge port face the direction of rotation of the perforated part.

[0010] Further, the rotating part in the support is provided with a rotating shaft, and the rotating part comprises a plurality of rotating discs which are fixed on the rotating shaft in parallel.

[0011] Further, the punching part is in a cylindrical shape, and the inner end of the punching part is screwed by a plurality of bolt assemblies penetrating the rotating disc, and the discharging port is located on the outer side of the rotating disc.

[0012] Further, the support further comprises a plurality of scraping mechanisms corresponding to the rotating discs respectively, each of the scraping mechanisms comprises a sliding sleeve which is arranged on the inner side of the support and extends towards the front side, a sliding part which is sleeved on the sliding sleeve in a front-rear limiting mode, and a return spring which is connected between the sliding sleeve and the sliding part, the front end of the sliding part is fixedly provided with a scraping part corresponding to the discharging gap, and the sliding part is rotatably provided with two abutting wheels corresponding to the left and right sides of the discharging gap, when the punching part on the lower side rotates upwards, the abutting wheels roll against the outer wall of the punching part and are pushed to roll towards the outer end, the scraping part is inserted into the punching channel and scrapes outward, and the sliding part is pushed to shrink, until the scraping part is separated from the punching channel, the abutting wheels are separated from the punching part, and then the sliding part is driven to reset by the front extension of the return spring.

[0013] Further, the sliding sleeve and the sliding part are arranged on the left and right sides of the corresponding rotating disc in a deviated mode, the sliding sleeve is provided with a limiting sliding channel penetrating in an axial direction on the side close to the corresponding rotating disc, the side wall of the sliding part is provided with a limiting part which is adapted to be sleeved in the limiting sliding channel, the front end of the sliding part is provided with a connecting shaft which extends towards the rotating disc, the upper end of the scraping part is fixedly sleeved on the outer wall of the connecting shaft, the lower end of the scraping part extends forward in a downward inclined mode, and the two abutting wheels are rotatably sleeved on the connecting shaft and are symmetrically arranged on the left and right sides of the scraping part.

[0014] Further, the upper end of the scraping part is provided with an outer diameter which is larger than the outer diameter of the lower end, and the outer diameter gradually decreases from the upper end to the lower end.

[0015] Further, the outer end of the punching part is provided with a plug-in hole part which gradually decreases in diameter from the inner end to the outer end.

[0016] Further, the top part of the support is provided with a top cover.

[0017] Therefore, the utility model provides the following effects and / or advantages:

[0018] 1. By adding a discharge gap and discharge port, when the rotating part drives several drilling parts to rotate and continuously drill holes toward the soil surface, the drilling channel of the lower drilling part is inserted into the soil and rotates backward to bring out the soil. As the drilling part continues to rotate, the soil in the drilling channel is discharged through the inner and outer ends of the drilling channel, the discharge port, and the discharge gap. This ensures that the drilling part can be inserted into the soil and bring out the soil to form a stable hole, thereby reducing the risk of the drilling channel becoming blocked after the drilling part has been working for a long time, improving the overall practicality and stability of the drilling attachment, and extending the service life of the drilling part.

[0019] 2. With the addition of the scraping mechanism, when the lower rear punch rotates upward, the abutment wheel rolls against the outer wall of the punch and is pushed outward, the scraper inserts into the punching channel and scrapes outward, and the sliding part is pushed back until the scraper disengages from the punching channel and the abutment wheel disengages from the punch. Then, the sliding part is driven to reset by the forward extension of the reset spring. This achieves the axial scraping of the punching channels of several punches by the reciprocating scraping action of the scraper. After scraping, the soil that is blocked at the inner end of the punching channel or stuck to the inner wall of the punching channel will be loosened and thrown out with the rotation of the punch. This avoids the situation where the inner end of the punching channel is blocked and the inner wall is stuck with soil, which affects the punching effect and improves the stability of the punch for long-term use.

[0020] 3. By offsetting the sliding sleeve and sliding component, without affecting the rotation stroke of the punching component, the sliding sleeve and sliding component can extend to the rotating components on two adjacent turntables, thereby increasing the contact area between the sliding sleeve and sliding component, reducing the risk of the sliding component breaking when pushed by the rotating component, and restricting the circumferential rotation of the sliding component through the cooperation between the limiting part and the limiting slide, thereby improving the stability of the scraping component and the overall stability of the scraping mechanism.

[0021] It should be understood that the above summary and the following detailed description of the present invention are exemplary and explanatory, and are intended to provide further explanation of the present invention as claimed. Attached Figure Description

Specifically, the rear side of the support 1 is used for mounting on a sliding vehicle, when the sliding vehicle moves, the support 1 drives the rotating member to rotate forward, the upper perforating member 3 rotates forward, and the lower perforating member 3 rotates backward and perforates the soil.

[0035] The above structure is provided by adding the axial gap 32 and the discharge port 33, when the rotating member drives the plurality of perforating members 3 to continuously perforate the soil, the perforating channel 31 of the lower perforating member 3 is inserted into the soil and rotated backward to bring out the soil, and as the perforating member 3 continues to rotate, the soil in the perforating channel 31 is discharged through the inner and outer ends of the perforating channel 31, the discharge port 33, and the axial gap 32, thereby ensuring that the perforating member 3 can insert the hole and bring out the soil to form a stable hole, reducing the risk of perforating channel 31 blockage after the perforating member 3 works for a long time, improving the practicability and stability of the perforating tool as a whole, and prolonging the service life of the perforating member 3.
