Description

Technical Field

[0001] This utility model belongs to the field of scallion seedling planting technology, specifically relating to a handheld hole punch for scallion planting. Background Technology

[0002] In the large-scale cultivation of scallions, handheld hole punches are commonly used to drill holes in the soil layer of the field to facilitate the rapid planting of scallion seedlings. However, the planting depth of scallion seedlings varies in sandy soil, clay soil, and ordinary loam. When using existing handheld hole punches, the drilling depth relies entirely on the operator's observation of the distance between the handle and the pressure plate, making it impossible to accurately judge the drilling depth and easily leading to significant errors in the depth of the planting holes. Furthermore, the planting holes made by the insertion rod of the handheld hole punch are all straight holes at the top. When the insertion rod is pulled out of the straight hole, the soil at the top of the planting hole easily loses support and falls back, causing blockage and requiring manual cleaning, which is time-consuming and labor-intensive. Moreover, during the drilling operation, when moving from one drilling position to the next, the operator needs to carry the handheld hole punch by hand the entire time. Scallion planting rows are usually long, and the operator's frequent lifting and carrying of the handheld hole punch can easily lead to fatigue, affecting the planting progress. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a handheld hole punch for planting scallions, which can effectively avoid clogging of straight holes and improve the consistency of planting hole depth, thus meeting the requirements for standardized planting depth of scallion seedlings.

[0004] The specific technical solution adopted in this utility model is as follows:

[0005] A handheld hole punch for scallion planting includes a soil pressing plate, an insertion rod, and an inverted T-shaped support rod. The support rod is located above the soil pressing plate. The insertion rod is fixedly connected to the support rod and is spaced apart along the axial direction of the support rod. The soil pressing plate has a first through hole for the insertion rod. A handle is fixedly connected to the upper end of the support rod. A connecting rod extends upward from the upper end of the soil pressing plate. The extended end of the connecting rod passes through the support rod and is detachably connected to the pressure plate. Crucially, the support rod is a split, detachable structure. A limiting platform is provided on the connecting rod within the support rod cavity. The handle has a second through hole for the extended end of the connecting rod to pass through. The diameter of the second through hole is smaller than the inner diameter of the support rod. The limiting platform cooperates with the handle to limit the insertion depth of the insertion rod. The limiting platform has the freedom to adjust its position along the axial direction of the connecting rod.

[0006] The lower end of the soil-pressing plate is provided with a set of frustum-shaped annular protrusions that are larger at the top and smaller at the bottom. The frustum-shaped annular protrusions are coaxially arranged with the first through hole. The inner diameter of the frustum-shaped annular protrusions is the same as the inner diameter of the first through hole. The diameter of the lower end of the frustum-shaped annular protrusions is larger than the diameter of the insertion rod.

[0007] The support rod includes a horizontal rod and a straight cylinder connected to the upper end of the horizontal rod. The insertion rod is set at the lower end of the horizontal rod and is arranged sequentially at intervals along the axial direction of the horizontal rod. The horizontal rod is provided with a guide hole for the connecting rod. The upper end of the straight cylinder is fixedly connected to the handle. The limiting platform is set inside the straight cylinder. The diameter of the second through hole is smaller than the inner diameter of the straight cylinder.

[0008] The limiting platform is a clamp, and a rubber ring is provided between the clamp and the connecting rod. A vertical sleeve is provided at the upper end of the horizontal rod, and the straight sleeve is connected to the horizontal rod by means of the vertical sleeve. The straight sleeve and the vertical sleeve are detachably connected.

[0009] The support rod is connected to the traveling wheel via a combined frame. The combined frame is located on one side of the support rod and includes a first rod, a second rod, and a third rod. The traveling wheel is located on the side of the support rod and is mounted on the first rod. The two ends of the second rod are hinged to the first rod and the support rod, respectively. The two ends of the third rod are hinged to the first rod and the support rod, respectively. The first rod is provided with a swing angle limiting part for the second or third rod. The traveling direction of the traveling wheel is parallel to the axial direction of the support rod.

[0010] The mounting ends of the second rod and the third rod are coaxially arranged and hinged to the support rod via a first hinge shaft. The cantilever end of the second rod is hinged to the first rod via a second hinge shaft. The first rod is provided with an elongated hole with its long axis arranged vertically. The cantilever end of the third rod is hinged to the elongated hole via a third hinge shaft and has the freedom to move along the long axis of the elongated hole. The elongated hole forms the swing angle limiting part of the second rod and the third rod.

[0011] The support rod is fitted with a sliding sleeve, which has the freedom to move up and down along the vertical direction of the support rod and is fixed to the support rod by means of a locking bolt. The second rod and the third rod are respectively hinged to the support rod by means of the sliding sleeve.

[0012] The cantilever end of the connecting rod is provided with scale lines.

[0013] The beneficial effects of this utility model are:

[0014] This utility model employs a limiting platform located within the straight cylindrical cavity of the support rod on the connecting rod. The limiting platform abuts against the handle to limit the insertion depth of the insertion rod. The limiting platform has the freedom to adjust its position along the axial direction of the connecting rod. According to the planting depth requirements of scallion seedlings in different soils, the height of the limiting platform on the connecting rod can be adjusted. When the handle is pressed down until it abuts against the limiting platform, it indicates that the insertion rod has reached the preset insertion depth, forming a planting hole of the preset height.

[0015] The extended end of the connecting rod is equipped with scale lines. Operators can quickly and intuitively judge the depth of the straight hole by referring to the scale lines corresponding to the handle, which facilitates precise control of the planting hole depth and standardizes the planting depth requirements of scallion seedlings in different soils.

[0016] A set of truncated cone-shaped annular protrusions, larger at the top and smaller at the bottom, is provided at the lower end of the soil compaction plate. The truncated cone-shaped annular protrusions are coaxially arranged with the first through hole, and the inner diameter of the truncated cone-shaped annular protrusions is the same as the inner diameter of the first through hole. The diameter of the lower end of the truncated cone-shaped annular protrusions is larger than the diameter of the insertion rod. The setting of the truncated cone-shaped annular protrusions further compacts the surface soil, reduces the looseness of the surface soil, and helps to reduce the generation of soil falling. In addition, the inclined wall of the conical hole changes the fall path of the soil. The soil will preferentially slide down the inclined wall, and the soil will generate moving friction on the inclined wall, reducing the amount of soil falling to the bottom of the conical hole. The bottom of the conical hole forms a flat area above the straight hole, and the soil will preferentially accumulate at the bottom of the conical hole instead of falling directly into the straight hole, thereby effectively reducing the risk of the straight hole being blocked and eliminating the need for manual cleaning of the planting hole.

[0017] The support rod is connected to a pair of wheels via a modular frame. When moving to the next drilling position after drilling is complete, pull the handle upward to separate the insert rod and soil-pressing plate from the soil. Move the handle towards the first rod in the modular frame to tilt the upper end of the support rod towards the first rod, causing the soil-pressing plate and insert rod to tilt upward. Push the handle forward, and the modular frame will transfer the force to the wheels, causing the wheels to rotate forward, thus moving the entire drill forward without requiring the operator to carry the drill forward, reducing manpower consumption. Folding the modular frame allows the support rod to be close to the wheels, reducing the space occupied by the drill and facilitating storage. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0025] Specific implementation examples Figure 1 , Figure 2 As shown, this utility model relates to a handheld hole punch for planting scallions, including a soil pressing plate 1, an insert rod 2, and an inverted T-shaped support rod 3. The support rod 3 is located above the soil pressing plate 1. The insert rod 2 is fixedly connected to the support rod 3 and is arranged sequentially at intervals along the axial direction of the support rod 3. The soil pressing plate 1 is provided with a first through hole 101 for the insert rod 2. A handle 4 is fixedly connected to the upper end of the support rod 3. A connecting rod 102 is suspended upward from the upper end of the soil pressing plate 1. The suspended end of the connecting rod 102 passes through the support rod 3 and is connected to a pressure plate 103. The pressure plate 103 is used to limit the rising height of the support rod 3. Crucially, as... Figure 4 As shown, the lower end of the soil-pressing plate 1 is provided with a set of frustum-shaped annular protrusions 104, which are larger at the top and smaller at the bottom. The frustum-shaped annular protrusions 104 are coaxially arranged with the first through hole 101. The inner diameter of the frustum-shaped annular protrusions 104 is the same as the inner diameter of the first through hole 101. The diameter of the lower end of the frustum-shaped annular protrusions 104 is larger than the diameter of the insert rod 2. The support rod 3 is provided with a guide hole 301 for the connecting rod 102. The connecting rod 102 is provided with an external thread above the scale line. The connecting rod 102 is screwed into the nut by means of the external thread, and the nut is located on the upper and lower sides of the pressure plate 103. The connecting rod 102 is fixedly connected to the pressure plate 103 by means of the nut.

[0026] During operation, the operator places the soil pressing plate 1 on the surface soil of the planting area and presses down together with the pressing plate 103 against the handle 4. The soil pressing plate 1 contacts the soil surface, and the frustum-shaped annular protrusion 104 on the soil pressing plate 1 forms a conical hole in the soil. The soil pressing plate 1 has a large contact area with the soil, and the soil pressing plate 1 acts as a support and does not move down. The operator applies downward pressure to the handle 4, causing the insertion rod 2 to continue to descend through the frustum-shaped annular protrusion 104 and insert into the soil to form a straight hole. The conical hole and the straight hole cooperate to form a planting hole.

[0027] The frustum-shaped annular protrusion 104 further compacts the surface soil, reducing its looseness and helping to minimize soil fall. Furthermore, the inclined walls of the conical hole alter the soil's fall path, creating a buffer zone above the straight hole. Falling soil preferentially slides along the inclined walls, generating friction that offsets some of the gravity, thus reducing the amount of soil falling to the bottom of the conical hole. The bottom of the conical hole forms a flat area above the straight hole, where falling soil also preferentially accumulates rather than falling directly into the straight hole, effectively reducing the risk of blockage. This eliminates the need for manual cleaning of the planting holes, facilitating the planting of scallion seedlings.

[0028] like Figure 5 As shown, the extended end of the connecting rod 102 is provided with a scale line 105. The operator can quickly and intuitively judge the depth of the straight hole according to the scale line 105 corresponding to the handle 4, which facilitates precise control of the depth of the planting hole and realizes the standardization of the planting depth requirements of scallion seedlings in different soils.

[0029] The support rod 3 includes a horizontal rod 302 and a straight cylinder 303 connected to the upper end of the horizontal rod 302. Insert rods 2 are disposed at the lower end of the horizontal rod 302 and spaced apart sequentially along the axial direction of the horizontal rod 302. A guide hole 301 is disposed on the horizontal rod 302. The upper end of the straight cylinder 303 is fixedly connected to a handle 4. The handle 4 is provided with a second through hole 401 for the cantilever end of the connecting rod 102 to pass through. The diameter of the second through hole 401 is smaller than the inner diameter of the straight cylinder 303. The connecting rod 102 is provided with... A limiting platform 106 is placed inside the cavity of the straight cylinder 303. The limiting platform 106 abuts and cooperates with the handle 4 to form a limiting depth of the insertion rod 2. The limiting platform 106 has the freedom to adjust its position along the axial direction of the connecting rod 102. According to the planting depth requirements of scallion seedlings in different soils, the height of the limiting platform 106 on the connecting rod 102 can be adjusted. When the handle 4 is pressed down to abut the limiting platform 106, it indicates that the insertion rod 2 has reached the preset insertion depth, forming a planting hole of the preset height.

[0030] Among them, the limiting platform 106 is a clamp, such as Figure 4 , Figure 5As shown, a rubber ring 107 is provided between the clamp and the connecting rod 102. The rubber ring 107 deforms under the pressure of the clamp and the connecting rod 102, increasing the friction between the clamp and the connecting rod 102 and making the connection between the clamp and the connecting rod 102 more secure. A vertical sleeve 304 is provided at the upper end of the horizontal rod 302. The straight cylinder 303 is connected to the horizontal rod 302 through the vertical sleeve 304. The lower end of the straight cylinder 303 is fitted into the vertical sleeve 304. The straight cylinder 303 and the vertical sleeve 304 are detachably connected. Preferably, a locking bolt 3 is installed on the vertical sleeve 304. 06. The overhanging end of the locking bolt 306 is located inside the cavity of the vertical sleeve 304 and abuts against the straight cylinder 303, thereby fixing the straight cylinder 303 and the vertical sleeve 304 together. Loosening the locking bolt 306 can separate the straight cylinder 303 from the vertical sleeve 304. The pressure plate 103 and nut can be removed from the connecting rod 102, and the straight cylinder 303 can be moved up along the connecting rod 102 until it is separated from the connecting rod 102. The limiting platform 106 on the connecting rod 102 is exposed, and the height of the limiting platform 106 on the connecting rod 102 can be adjusted to control the insertion depth of the insertion rod 2 in the soil.

[0031] like Figure 3 As shown, the support rod 3 is connected to a pair of wheels 6 via a combined frame 5. The combined frame 5 is located on one side of the support rod 3 and includes a first rod 501, a second rod 502, and a third rod 503. The wheels 6 are located on the side of the support rod 3 and are mounted on the first rod 501. The two ends of the second rod 502 are hinged to the first rod 501 and the support rod 3, respectively. The two ends of the third rod 503 are also hinged to the first rod 501 and the support rod 3, respectively. The first rod 501 is provided with either the second rod 502 or the third rod 503. The sway limiter and the traveling wheel 6 are set parallel to the axis of the support rod 3. When the drilling is completed and the machine moves to the next drilling position, the handle 4 is pulled up to separate the insertion rod 2 and the soil pressing plate 1 from the soil. The handle 4 is then pulled towards the first rod 501 to tilt the upper end of the support rod 3 toward the first rod 501. The soil pressing plate 1 and the insertion rod 2 tilt upward. The handle 4 is pushed forward, and the combined frame 5 transmits the force to the traveling wheel 6. The traveling wheel 6 rotates forward, realizing the overall forward movement of the drill. This eliminates the need for the operator to carry the drill forward, reducing manpower consumption.

[0032] Specifically, the mounting ends of the second rod 502 and the third rod 503 are coaxially arranged and hinged to the support rod 3 via the first hinge shaft 504. The cantilever end of the second rod 502 is hinged to the first rod 501 via the second hinge shaft 505. The first rod 501 is arranged vertically and has an elongated hole 506 with its major axis arranged vertically. The cantilever end of the third rod 503 is hinged to the elongated hole 506 via the third hinge shaft 507 and has the freedom to move along the major axis of the elongated hole 506. The elongated hole 506 forms the swing angle limiting part of the second rod 502 and the third rod 503. When in the working state, the third hinge shaft 507... The second rod 502 is positioned horizontally and abuts against the bottom of the elongated hole 506. Under the action of gravity, the straight cylinder 303 of the support rod 3 remains vertical, facilitating the vertical insertion of the insertion rod 2 into the soil. A stable triangular structure is formed between the first rod 501, the second rod 502, and the third rod 503. When the punch is stored, the support rod 3 and the second rod 502 rotate around the second hinge axis 505, the third hinge axis 507 moves along the long axis of the elongated hole 506, and the third rod 503 rotates around the axis of the third hinge axis 507. The support rod 3 moves close to the traveling wheel 6, realizing the overall folding of the punch and reducing the horizontal area occupied by the punch for storage.

[0033] Preferably, a sliding sleeve 305 is fitted onto the straight cylinder 303 of the support rod 3. The sliding sleeve 305 has the freedom to move up and down along the axial direction of the straight cylinder 303. The sliding sleeve 305 is fixedly connected to the support rod 3 by means of a locking bolt 306. The second rod 502 and the third rod 503 are respectively hinged to the support rod 3 by means of the sliding sleeve 305. The locking bolt 306 is installed on the sliding sleeve 305. The overhanging end of the locking bolt 306 extends into the sliding sleeve 305 and abuts against the straight cylinder 303 of the support rod 3, thereby realizing the fixed connection between the sliding sleeve 305 and the support rod 3. Loosening the locking bolt 306 on the sliding sleeve 305 can adjust the height of the sliding sleeve 305 on the support rod 3, thereby adjusting the height of the traveling wheel 6 relative to the support rod 3, so as to meet the needs of the puncher to punch holes on flat ground or ridge top. When punching holes on the ridge top, the traveling wheel 6 travels in the furrow.
