Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a punching device for a small transplanter. Background Art

[0002] At present, the planting mechanism of small self-propelled vegetable seedling transplanters generally includes a seedling delivery component, a transplanting arm, and a punching component connected to the transplanting arm. Among them, the punching component is mainly composed of a seedling grafting funnel, a mounting block, and a punching cone that can be opened and closed in half, which are connected in series from top to bottom. The planting process is generally that the transplanting arm drives the punching component to move back and forth up and down, and the seedling delivery component drops the vegetable seedlings into the seedling grafting funnel that moves up to below it, and the vegetable seedlings fall directly into the closed punching cone. Then the punching cone moves down and inserts into the soil and opens to both sides, thereby completing the transplanting of the vegetable seedlings.

[0003] The soil around the vegetable seedlings after transplanting in the above-mentioned perforated cones is relatively loose, which causes some vegetable seedlings to easily fall over during their later growth process, affecting the survival rate of the vegetable seedlings. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a small-scale transplanting machine punching device, the specific technical solution is as follows:

[0005] The utility model provides a punching device for a small transplanter, comprising a mounting block, a circular hole extending through the middle of the mounting block, a seedling grafting funnel axially connected to the top of the circular hole, a punching cone cylinder axially suspended at the bottom thereof, an elastic soil pressing mechanism axially sleeved on the outside of the punching cone cylinder, the elastic soil pressing mechanism comprising a soil pressing plate sleeved at the lower part of the punching cone cylinder at radially symmetrical intervals, the soil pressing plate being a semicircular structure, a guide rod detachably connected vertically to the middle part of the top surface thereof, the gap at the top of the guide rod passing through a suspension assembly vertically fixed to the side of the corresponding mounting block; an elastic spring tube axially sleeved on the guide rod, the top end of the elastic spring tube being detachably connected to the suspension assembly, and the bottom end thereof being detachably connected to the soil pressing plate.

[0006] As a preferred technical solution of the present invention, the suspension assembly includes a U-shaped frame fixed vertically to the side surface of the corresponding mounting block, and the inner side surfaces of the longitudinal portion of the U-shaped frame are symmetrically provided with linear slide grooves, and a slider is slidably connected between the two linear slide grooves, and the slider is gap-connected with the guide rod, and an adjusting screw is fixed vertically to the outer end surface of the slider, and the outer end of the adjusting screw gap passes through the transverse portion of the U-shaped frame, and the adjusting screw is maintained in left and right clamping connection with the transverse portion of the U-shaped frame by two positioning nuts axially threaded thereon.

[0007] As a preferred technical solution of the present invention, a pad is vertically fixed to the bottom end of the guide rod, and the pad is screwed and fixed to the corresponding soil pressing plate through fastening bolts at the end thereof.

[0008] As a preferred technical solution of the present invention, the elastic spring tube includes a return spring axially sleeved with the guide rod, and the outer axial sleeve of the return spring is matched with a telescopic sleeve; the top end of the return spring is sleeved with a spring seat fixed to the bottom surface of the U-shaped frame, and the bottom end is sleeved with a spring seat fixed to the top surface of the pad, and the guide rod passes through the spring seat.

[0009] As a preferred technical solution of the present invention, the top end of the guide rod is axially threadedly connected to a limiting nut.

[0010] As a preferred technical solution of the present invention, the outer edge of the top surface of each half of the punching cone is radially connected to a swing frame, and the two swing frames are cross-hinged to the corresponding side surfaces of the mounting block through matching pins.

[0011] The beneficial effects of the utility model are:

[0012] The utility model provides an elastic soil pressing mechanism axially sleeved on the outer side of the perforated cone. When the perforated cone moves downward and is inserted into the soil and opens to both sides to complete the transplanting of the vegetable seedlings, the soil pressing plates will be pressed into the soil accordingly. Since the soil pressing plates are of a semicircular structure and are radially symmetrically spaced, they can effectively compact the soil around the vegetable seedlings, reduce the looseness of the soil, and thus enhance the supporting force of the soil for the vegetable seedlings. In this way, the vegetable seedlings are less likely to fall over during the later growth process, and the survival rate of the vegetable seedlings is greatly improved.

[0013] The elastic spring tube allows the pressure plate to adapt to the hardness and density of the soil. When the soil is harder, the spring tube is subjected to greater compression, forcing the pressure plate into the soil with greater force. When the soil is softer, the spring tube is compressed less, forcing the pressure plate into the soil with less force. This adaptive adjustment allows the punching device to better adapt to different soil conditions, ensuring stable and consistent transplanting results.

[0014] The guide rod, elastic spring tube and soil pressing plate and other components can be detachably connected to the suspension assembly. This design allows these components to be easily replaced and maintained after damage or wear, reducing the cost of use and extending the service life of the equipment.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Example 1

[0025] In order to solve the technical problems in the background technology, a punching device for a small transplanter is provided as follows:

[0026] Combine Figure 1 、 Figure 2 as well as Figure 6 、 Figure 7As shown, a punching device for a small transplanter comprises a mounting block 1, wherein a circular hole is formed through the middle of the mounting block 1, a seedling grafting funnel 2 is axially connected to the top of the circular hole, and a punching cone 4 opened in half is axially suspended at the bottom thereof, an elastic soil pressing mechanism 5 is axially sleeved on the outside of the punching cone 4, and the elastic soil pressing mechanism 5 comprises a soil pressing plate 51 which is radially symmetrically sleeved on the lower part of the punching cone 4, the soil pressing plate 51 is a semicircular structure, and a guide rod 52 is detachably connected vertically to the middle of its top surface, and the top gap of the guide rod 52 passes through a suspension assembly 53 vertically fixed to the side of the corresponding mounting block 1; an elastic spring tube 54 is axially sleeved on the guide rod 52, and the top end of the elastic spring tube 54 is detachably connected to the suspension assembly 53, and the bottom end thereof is detachably connected to the soil pressing plate 51.

[0027] By adopting the above technical solution, the punching device is provided with an elastic soil pressing mechanism 5 axially sleeved on the outside of the punching cone 4. When the punching cone 4 is moved down and inserted into the soil and opened to both sides to complete the transplanting of the vegetable seedlings, the soil pressing plate 51 will be pressed into the soil accordingly; since the soil pressing plates 51 are semicircular in structure and radially symmetrically spaced, they can effectively compact the soil around the vegetable seedlings, reduce the looseness of the soil, thereby enhancing the soil's support for the vegetable seedlings, so that the vegetable seedlings are less likely to fall over during the later growth process, thereby greatly improving the survival rate of the vegetable seedlings;

[0028] The provision of the elastic spring tube 54 enables the pressure plate 51 to adapt to the hardness and density of the soil to a certain extent. When the soil is hard, the elastic spring tube 54 is subjected to a greater compressive force, causing the pressure plate 51 to press into the soil with greater force. When the soil is soft, the elastic spring tube 54 is compressed less, and the pressure plate 51 presses into the soil with relatively less force. This adaptive adjustment capability enables the punching device to better adapt to different soil conditions, ensuring stable and consistent transplanting results.

[0029] The guide rod 52, elastic spring tube 54 and soil pressing plate 51 and other components can be detachably connected to the suspension assembly 53. This design allows these components to be easily replaced and maintained after damage or wear, reducing the cost of use and extending the service life of the equipment.

[0030] like Figure 1 and Figure 2 As shown, the outer edge of the top surface of each half of the punching cone 4 is radially connected to a swing frame 3, and the two swing frames 3 are cross-hinged to the corresponding side surfaces of the mounting block 1 through matching pins 11.

[0031] By adopting the above technical solution, the two swing frames 3 are cross-hinged with the pin 11, and the punch cone 4 can achieve better stability during its up and down reciprocating movement. This cross-hinged method enables the punch cone 4 to form a stable triangular structure when subjected to force, effectively preventing it from shaking or tilting during the transplanting process. At the same time, it allows the punch cone 4 to more easily open to both sides after being inserted into the soil, thereby successfully completing the transplanting of vegetable seedlings.

[0032] Preferably, the two swing frames 3 are driven to rotate crosswise by pneumatic elements, thereby driving the punching cone 4 to open and close freely.

[0033] Example 2

[0034] Combine Figures 2 to 4 as well as Figure 6 、 Figure 7 As shown, based on the above embodiment, this embodiment further provides the following content:

[0035] In this embodiment, if Figure 2 、 Figure 3 as well as Figure 6 、 Figure 7 As shown, the suspension assembly 53 includes a U-shaped frame 531 fixed vertically to the side of the corresponding mounting block 1, and the inner side surfaces of the longitudinal portion of the U-shaped frame 531 are symmetrically provided with linear slide grooves 5311, and a slider 532 is slidably connected between the two linear slide grooves 5311, and the slider 532 is gap-connected with the guide rod 52, and the outer end surface of the slider 532 is vertically fixed with an adjusting screw 533, and the outer end gap of the adjusting screw 533 passes through the transverse portion of the U-shaped frame 531, and the adjusting screw 533 is maintained in left and right clamping connection with the transverse portion of the U-shaped frame 531 by two positioning nuts 534 axially screwed thereon.

[0036] By adopting the above technical solution, the suspension assembly 53 is composed of a U-shaped frame 531, a slider 532, an adjusting screw 533 and a positioning nut 534. In this way, by loosening the positioning nut 534, pushing and pulling the adjusting screw 533, and then tightening the positioning nut 534, the lateral position of the slider 532 can be adjusted within a certain range, so that the position of the soil pressing plate 51 also changes accordingly, so as to adjust the opening degree of the punching cone 4 to adapt to vegetable seedlings of different sizes.

[0037] like Figure 3 and Figure 4 As shown, the top end of the guide rod 52 is axially threadedly connected to a limiting nut 521 .

[0038] By adopting the above technical solution, the set limit nut 521 can prevent the guide rod 52 from moving downward excessively under the elastic force of the elastic spring tube 54 and detaching from the slider 532; the screw connection between the limit nut 521 and the guide rod 52 makes it more convenient when maintenance or replacement of parts is required.

[0039] Example 3

[0040] Combine Figures 1 to 7 As shown, based on the above embodiment, this embodiment further provides the following content:

[0041] In this embodiment, if Figures 4 to 7 As shown, a pad 522 is vertically fixed to the bottom end of the guide rod 52, and the pad 522 is screwed and fixed to the corresponding soil pressing plate 51 through a fastening bolt 5221 at its end.

[0042] By adopting the above technical solution, the pad 522 is vertically fixed to the bottom end of the guide rod 52, and is screwed to the corresponding soil pressure plate 51 through the fastening bolts 5221 at its end. This design significantly enhances the connection stability between the guide rod 52 and the soil pressure plate 51; the design of the fastening bolts 5221 allows the user to easily install or remove the pad 522 and the soil pressure plate 51 as needed, which not only facilitates the maintenance and maintenance of the equipment, but also improves the maintainability and replaceability of the equipment.

[0043] like Figures 1 to 4 As shown, the elastic spring tube 54 includes a return spring 541 axially sleeved with the guide rod 52, and the outer axial sleeve of the return spring 541 is matched with a telescopic sleeve 542; the top end of the return spring 541 is sleeved with a spring seat 523 fixed to the bottom surface of the U-shaped frame 531, and the bottom end is sleeved with a spring seat 523 fixed to the top surface of the pad 522. The guide rod 52 passes through the spring seat 523.

[0044] By adopting the above technical solution, the return spring 541 inside the elastic spring tube 54 provides the necessary elastic soil-compacting force for the soil-pressing plate 51. When the perforated cone 4 is inserted into the soil and opened, the soil-pressing plate 51, under the elastic force of the return spring 541, adheres tightly to the soil surface, compacting the surrounding soil. This compaction effectively reduces soil looseness, increases the soil's support for the vegetable seedlings, and thus reduces the risk of the seedlings falling over.

[0045] The sleeve-fitting connection between the telescopic sleeve 542 and the reset spring 541 not only provides the necessary elastic force, but also ensures that soil does not enter the interior of the reset spring 541 , thereby affecting the elastic force of the reset spring 541 .

[0046] The working principle and use process of this utility model:

[0047] When the utility model is in use, first, the transplanting arm drives the entire punching device to move above the soil to be transplanted, and at this time the punching cone 4 is in a closed state;

[0048] As the transplanting arm descends, the perforated cone 4 first receives the vegetable seedlings sent by the seedling delivery assembly through the seedling receiving funnel 2; the perforated cone 4 continues to move downward until its tip is inserted into the soil; at this time, the perforated cone 4 overcomes the soil resistance and opens to both sides, releasing the vegetable seedlings into the soil and forming a hole suitable for the growth of the vegetable seedlings' roots;

[0049] At the same time, the elastic soil pressing mechanism 5 begins to work. Under the elastic force of the return spring 541, its soil pressing plate 51 is in close contact with the soil surface, compacting the soil around the hole. During the compaction process, the telescopic sleeve 542 not only limits the radial deformation of the return spring 541, but also prevents the soil from entering the interior of the return spring 541. At the same time, the sliding fit connection between the guide rod 52 and the suspension assembly 53 allows the soil pressing plate 51 to adjust its lateral position within a certain range, thereby adjusting the opening degree of the punching cone 4 to accommodate vegetable seedlings of different sizes.

[0050] When the transplanting arm rises and drives the punching device out of the soil, the return spring 541 gradually returns to its original state under the action of the spring seat 523 and the pad 522, driving the soil pressing plate 51 back to its initial position; at this time, the punching device has completed a complete transplanting and compacting action.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
