Description

Technical Field

[0001] This utility model belongs to the field of potato planting technology, specifically relating to a potato tissue culture seedling substrate cutting hole punch. Background Technology

[0002] In the cultivation and transplanting of potato tissue culture seedlings, substrate cutting and hole drilling is a crucial and time-consuming operation. Traditional hole drilling methods mainly rely on manual operation, such as using shovels or special drilling tools to drill holes one by one. This method is not only labor-intensive and inefficient, but also makes it difficult to ensure the uniformity of plant spacing and depth of drilling, which has an adverse effect on the subsequent growth and yield of potato tissue culture seedlings.

[0003] With the continuous improvement of agricultural mechanization, some mechanized drilling equipment has gradually appeared on the market. However, these devices often have problems such as complex structure, inconvenient operation, and high cost. Moreover, most of them are designed for field crops and are not very suitable for crops such as potato tissue culture seedlings that require precise control of plant spacing and drilling depth.

[0004] Furthermore, existing drilling equipment typically has a fixed plant spacing adjustment mechanism, which cannot be flexibly adjusted according to different planting needs, thus limiting its application in various planting modes. At the same time, when driving multiple drilling rods simultaneously, problems such as unstable driving and uncoordinated movements between the drilling rods often occur, resulting in inconsistent drilling quality and affecting planting results.

[0005] To address the aforementioned issues, there is an urgent market need for a potato tissue culture seedling substrate cutting hole punch that is simple in structure, easy to operate, moderately cost-effective, and capable of flexibly adjusting plant spacing and simultaneously driving multiple punching rods. This hole punch needs to ensure punching efficiency while achieving precise control of the plant spacing and consistently improving punching quality to meet the demands of refined potato tissue culture seedling cultivation. Utility Model Content

[0006] To address the above problems, the purpose of this utility model is to provide a potato tissue culture seedling substrate cutting hole puncher, which solves the problems of existing potato cutting hole punchers being unable to flexibly adjust plant spacing and stably drive multiple punching rods synchronously.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a potato tissue culture seedling substrate cutting hole punch, comprising a base frame, the base frame being connected to a top frame via a lifting mechanism, a fixed rod and a motor being fixedly mounted on the top frame, a scissor-type linkage mechanism being mounted on the fixed rod, the scissor-type linkage mechanism comprising multiple connecting rods one and two, the ends of connecting rods one and two at both ends of the scissor-type linkage mechanism being rotatably connected via transmission components two and three respectively, the ends of the remaining connecting rods one and two being rotatably connected via connecting pins, the middle ends of connecting rods one and two being rotatably connected via transmission component one, transmission component two being slidably mounted on the fixed rod, transmission component three being rotatably connected to the fixed rod, a soil-drilling rod being mounted at the bottom end of transmission component one, and the motor being connected to transmission component one via a transmission mechanism.

[0008] The beneficial effects of this utility model are as follows: through the design of the scissor linkage mechanism and the transmission mechanism, the spacing between multiple drill rods can be flexibly adjusted and synchronously driven, which not only improves drilling efficiency and quality, but also reduces operation difficulty and cost.

[0009] To ensure stable lifting and lowering of the top frame;

[0010] As a further improvement to the above technical solution: the lifting mechanism includes an electric cylinder and a guide rod.

The top end of the push rod of the electric cylinder is connected to the top frame. The guide rod slides through the top frame.

The fixing rod is a channel steel structure, and the flanges on both sides of the fixing rod are bent inward with support plates. The outer side of the bushing is formed with an annular groove and is slidably fitted between the support plates on both sides.

[0014] The beneficial effects of this improvement are: the shaft can rotate smoothly under the support of the bushing, driving the drill rod to rotate stably.

[0015] To ensure the stability of the connection between transmission component two and the fixed rod;

The outer side of the bushing two is formed with an annular groove and is rotatably clamped on the sliding sleeve. The sliding sleeve is slidably fitted on the fixed rod.

[0017] The beneficial effects of this improvement are: the second shaft can rotate smoothly under the support of the second bushing, and the sliding sleeve can slide smoothly on the outside of the fixed rod, thereby driving one end of the scissor linkage mechanism to move, so as to adjust the spacing between multiple drill rods.

[0018] To facilitate and securely lock the spacing between multiple drill rods;

[0019] As a further improvement to the above technical solution: the transmission component 2 has a through hole for a sliding bolt, and the fixing rod has multiple positioning holes spaced at equal intervals, with the positioning holes being threadedly connected to bolts.

[0020] The beneficial effect of this improvement is that the operator can quickly and securely lock the position of the transmission component two by rotating the bolt to connect the bolt with the positioning hole, thereby locking the spacing between multiple drill rods.

[0021] To ensure the stability of the connection between the transmission component three and the fixed rod;

[0022] As a further improvement to the above technical solution: the transmission component three includes a shaft three, both the upper and lower ends of the shaft three are formed with journals, and the outer sides of the upper and lower journals are respectively rotatably fitted with bushing three, connecting rod one, and connecting rod two.

The outer side of the bushing two is formed with an annular groove and is rotatably clamped between the limiting plates on both sides. A circular groove structure is formed between the two limiting plates. The limiting plates are fixed on the fixed rod.

[0023] The beneficial effect of this improvement is that the shaft can rotate stably under the support of the bushing and the limiting plate.

[0024] In order to effectively improve the structural strength of the fixing rod;

[0025] As a further improvement to the above technical solution: a reinforcing plate is welded between the two flanges of the fixing rod, and the reinforcing plate is parallel to the web of the fixing rod.

[0026] The beneficial effect of this improvement is that the reinforcing plate can effectively improve the overall structural strength of the fixing rod.

[0027] To ensure stable power transmission of the transmission mechanism when the scissor-type linkage mechanism rotates and deforms;

[0028] As a further improvement to the above technical solution: the transmission mechanism is composed of multiple chain transmission mechanisms, and the sprockets in each chain transmission mechanism are respectively installed on two adjacent transmission components and the connecting pin between the two transmission components. The transmission component one is equipped with two sprockets from the chain transmission mechanisms, and the transmission components two and three are each equipped with sprockets from the transmission mechanisms.

[0029] The beneficial effect of this improvement is that multiple sets of parallelogram-shaped chain drive mechanisms, each consisting of four sprockets and one chain, can stably transmit power to the drill rod.

After adjustment, screw the bolt 84 into the corresponding positioning hole 41 to lock it. During operation, push the equipment to... Align the drill rod 11 with the area to be drilled in the substrate, start the electric cylinder 21 to raise the top frame 3, and move the drill rod 11 to the appropriate height; turn on the motor 10, and drive the drill rod 11 to rotate through the transmission mechanism 6. Then control the electric cylinder 21 to descend to drill. After drilling is completed, the electric cylinder 21 drives the drill rod 11 to rise and reset. Move the equipment to the next area and repeat the operation. After use, clean the residual substrate on the surface of the drill rod 11, check the transmission mechanism 6 chain, connecting pin 53, bolt 84 and other components, lubricate the transmission components regularly, and stop the machine for maintenance in time if any abnormality occurs to ensure stable operation of the equipment.
