Description

Technical Field

[0001] The present application relates to the technical field of punchers, and more specifically, to a seedling puncher. Background Art

[0002] Watermelon seedlings require pre-drilling before transplanting. Traditional drilling is typically done manually with a hoe, which is time-consuming, labor-intensive, inefficient, and prone to large errors. Mulching with film mulch can increase soil temperature, retain moisture, improve soil physical and chemical structure, increase fertilizer utilization, and reduce weeds, pests, and diseases. Therefore, this cultivation method has become widely used in watermelon production. However, traditional mulching with film mulch is not only time-consuming and labor-intensive, but also inefficient, and the hole spacing varies widely, making it unsuitable for watermelon cultivation.

[0003] The document with prior art publication number CN 206629418 U provides a watermelon seedling transplanting puncher. The puncher has an elastic recovery function. The elastic recovery effect of the spring is used to push out the soil embedded in the hole-shaped mold, eliminating the need to manually unload the soil by stepping on it, thus saving labor. The utility model uses a hollow hole-shaped mold as the main structure. The hole-shaped mold is embedded in the soil with the help of the downward pressure of the human body. When the hole-shaped mold is separated from the soil, the soil in the hole-shaped mold is brought out to form a hole. The hole is thus punched in a one-press-one-lift operation. The utility model is equipped with a ruler to accurately locate the punching position during the punching process. Holes with uniform distribution and appropriate hole spacing are conducive to better growth of plants.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is in use, the aperture of the punched hole cannot be adjusted when punching through the hole-shaped mold, which makes it impossible to punch and sow seedlings of different sizes.

[0005] In view of this, we propose a seedling puncher. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] The purpose of this application is to provide a seedling puncher that solves the technical problems in the above-mentioned background technology and realizes the adjustment of the punching hole diameter to adapt to the technical effects of different seedling sowing.

[0008] 2. Technical solution

[0009] The technical solution of the present application provides a seedling puncher, comprising: a support frame, a conical head is fixed at the lower end of the support frame, the lower end of the conical head is a tip, the lower end of the support frame is elastically connected to a ring plate, the ring plate is coaxially arranged with the conical head, the ring plate is threadedly connected with a plurality of long screws, and the conical head comprises an inverted frustum and a vertical pipe coaxially fixed with the frustum and a conical head coaxially fixed with the vertical pipe.

[0010] By adopting the above technical solution, multiple long screws are spirally adjusted to form an opening between the multiple long screws, and the inner diameter of the opening is adjusted by adjusting the multiple long screws. When the ring plate is against the ground, the support frame is pressed downward, the cone head breaks the ground and drills a hole of a certain depth after breaking the ground through the riser. When the cone is against the long screw, the cone will not continue to fall, thereby realizing the adjustment of the top opening diameter after drilling. After the support frame is lifted, the ring plate is reset under the action of elastic rebound.

[0011] As an optional solution to the technical solution of this application document, the support frame includes a handle and a support rod fixing rod, the handle is vertically fixed with two support rods, and multiple fixing rods are vertically fixed on the support rods. The fixing rods are provided with guide holes parallel to the support rods, and the ring plate is symmetrically fixed with guide rods, and the guide rods are slidably inserted into the guide holes, and multiple springs are fixed between the fixing rods and the ring plate.

[0012] By adopting the above technical solution, the handle is held and the whole is pressed against the ground, and the ring plate is pressed against the ground. When the ring plate is pressed against the ground and moves toward the fixed rod, the spring is compressed and an elastic rebound force is generated at the same time. Under the elastic rebound action of the spring, the ring plate elastically rebounds when it is not under pressure, and the guide rod slides vertically along the guide hole to ensure that the cone head and the ring plate are always in a coaxial state.

[0013] As an optional solution to the technical solution of this application document, the long screw has multiple scale grooves distributed axially.

[0014] By adopting the above technical solution, when each scale groove of the rotating long screw is opposite to the outer wall of the ring plate, the diameter formed between the multiple long screws corresponds to the position of a frustum. When each frustum is against the long screw, it corresponds to the diameter of a punched hole. Then, by rotating the long screw and observing the position of the scale groove, it is easy to judge the diameter size after the frustum is opened.

[0015] As an optional solution to the technical solution of this application document, the conical head is a hollow structure, and a pedal is fixed on one side of the conical head.

[0016] By adopting the above technical solution, the hollow structure of the conical head can reduce the overall weight and the load on the user, and the pedals can be used to apply force by stepping on the pedals with the soles of the feet.

[0017] As an optional solution to the technical solution of this application document, the handle is vertically fixed with a vertical pole, and a counterweight block is slidably inserted into the vertical pole.

[0018] By adopting the above technical solution, the ring plate is pressed against the ground, and when the spring is in a compressed state, one hand holds the handle, and the other hand lifts the counterweight block upward and then puts it down. At this time, when the counterweight block falls and hits the handle, the inertial force causes the conical head to be inserted into the soil.

[0019] 3. Beneficial effects

[0020] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0021] 1. The present application forms an opening between multiple long screws by spirally adjusting the multiple long screws, and the inner diameter of the opening is adjusted by adjusting the multiple long screws. Then, when the ring plate is against the ground, the support frame is pressed downward, the cone head breaks through the ground and drills a hole of a certain depth after breaking through the ground through the riser. When the cone hits the long screws, the cone will not continue to drop, thereby realizing the adjustment of the diameter of the top opening after drilling. After the support frame is lifted, the ring plate is reset under the action of elastic rebound. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present application is further described in detail below with reference to the accompanying drawings.

[0027] A seedling puncher includes: a support frame 1, a conical head 2 is fixed at the lower end of the support frame 1, the lower end of the conical head 2 is a tip, the lower end of the support frame 1 is elastically connected to a ring plate 3, the ring plate 3 is coaxially arranged with the conical head 2, the ring plate 3 is threadedly connected with multiple long screws 4, the conical head 2 includes an inverted frustum 22 and a vertical pipe 23 coaxially fixed with the frustum 22 and a conical head 24 coaxially fixed with the vertical pipe 23.

[0028] Reference Figure 1-Figure 3 By spirally adjusting multiple long screws 4, an opening is formed between the multiple long screws 4, and the inner diameter of the opening is adjusted by adjusting the multiple long screws 4. Then, when the ring plate 3 is against the ground, the support frame 1 is pressed downward, the cone head 24 breaks the ground and drills a hole of the depth after breaking the ground through the riser 23. When the frustum 22 is against the long screw 4, the frustum 22 will not continue to fall, thereby realizing the adjustment of the top opening diameter after drilling. After the support frame 1 is lifted, the ring plate 3 is reset under the action of elastic rebound.

[0029] The support frame 1 includes a handle 12 and a support rod 11 fixing rod 13. The handle 12 is vertically fixed with two support rods 11. Multiple fixing rods 13 are vertically fixed on the support rod 11. The fixing rod 13 is provided with a guide hole 131 parallel to the support rod 11. The ring plate 3 is symmetrically fixed with a guide rod 31. The guide rod 31 is slidably inserted into the guide hole 131. Multiple springs 32 are fixed between the fixing rod 13 and the ring plate 3.

[0030] Reference Figure 2 and Figure 3 , hold the handle 12, press the whole to the ground, and make the ring plate 3 rest against the ground. When the ring plate 3 rests against the ground and moves toward the fixed rod 13, the spring 32 is compressed and generates an elastic rebound force. Under the elastic rebound action of the spring 32, the ring plate 3 elastically rebounds when it is not under pressure, and the guide rod 31 slides vertically along the guide hole 131 to ensure that the cone head 24 and the ring plate 3 are always in a coaxial state.

[0031] The long screw 4 has a plurality of scale grooves 41 distributed axially.

[0032] Reference Figure 3 When each scale groove 41 of the rotating long screw 4 is opposite to the outer wall of the ring plate 3, the diameter formed between the multiple long screws 4 corresponds to the position of a cone 22. When each cone 22 is against the long screw 4, it corresponds to the diameter of a punched hole. Then, by rotating the long screw 4 and observing the position of the scale groove 41, it is easy to judge the diameter of the cone 22 after it is opened.

[0033] The conical head 2 is a hollow structure, and a pedal 22 is fixed to one side of the conical head 2 .

[0034] Reference Figure 2The hollow structure of the conical head 2 is used to reduce the overall weight and the load on the user, and the pedal 22 is used to apply force by stepping on the pedal 22 with the sole of the foot.

[0035] A vertical rod 14 is vertically fixed to the handle 12 , and a counterweight 15 is slidably inserted into the vertical rod 14 .

[0036] Reference Figure 2 , place the ring plate 3 against the ground, and when the spring 32 is compressed, hold the handle 12 with one hand, and lift the counterweight 15 upward with the other hand, and then put it down. At this time, when the counterweight 15 falls and hits the handle 12, the inertia force causes the conical head 2 to be inserted into the soil.

[0037] Working principle: Rotate the long screw 4 to adjust the caliber formed between the multiple long screws 4, and make the corresponding scale grooves 41 on the multiple long screws 4 correspond to the outer edge of the ring plate 3, then stick the ring plate 3 to the ground, and then step on the pedal 22 and apply force through the legs to make the cone head 24 insert into the soil. The cone head 24 breaks the soil and drills a hole to the depth after breaking the soil through the standpipe 23. When the cone 22 is against the long screw 4, the cone 22 will not continue to fall, and the drilling can be completed. When the whole is lifted, the ring plate 3 is reset under the elastic rebound action of the spring 32.
