Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an adjustable punching device for adjusting the planting spacing of plants. Background Technology

[0002] In plant cultivation, the first step is to drill holes to create the necessary planting spaces, and then plant the plants within these holes. Currently, there is limited machinery suitable for small-scale or limited-area plant cultivation. For example, greenhouse cultivation typically involves strip planting surfaces 1-2 meters wide. Drilling these holes requires a small drilling device. Existing drilling devices cannot adjust the spacing between plants in the holes, which significantly impacts crop growth and yield. Different operations often require different spacing. Traditional methods only design one drilling device for the specific spacing requirements of a particular crop, limiting the flexibility of the device and its usability. To address these issues, it is necessary to conduct structural research, design, and innovative breakthroughs in drilling devices for agricultural machinery (these devices can also be adapted and mounted on agricultural machinery as drilling components).

After adjustment, the planting spacing is maintained, and the same planting crop or plants with the same planting spacing requirement are punched sequentially. In this way, the planting spacing is adjusted and the same planting crop can be continuously punched.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the embodiments:

[0025] Example 1

[0026] An adjustable punching device for adjustable plant spacing includes a base horizontal frame 1 and a punching device 8. At least one movable device mounting frame 2 is fixed on the base horizontal frame 1. In embodiment one, one movable device mounting frame 2 is fixed on the base horizontal frame 1; alternatively, multiple movable device mounting frames 2 can be arranged side-by-side, or more can be added side-by-side. A displacement driving device 3 is mounted on the movable device mounting frame 2. The displacement driving device 3 includes a displacement adjusting screw 31 and a screw nut 32 that cooperates with the displacement adjusting screw 31. The displacement adjusting screw 31 is rotatably mounted on the movable device mounting frame 2, and a wheel 34 is fixed to the outer end of the displacement adjusting screw 31. A displacement slide rail 4 parallel to the displacement adjusting screw 31 is fixed to the base horizontal frame 1 or the movable device mounting frame 2. A displacement slider 35, linearly sliding at the upper limit of the displacement slide rail 4, is fixed to the screw nut 32. A balance slide bar 5, parallel to the displacement slide rail 4, is fixed on the base horizontal frame 1 or the moving device mounting frame 2. A guide rod slide cylinder 51 is slidably fitted on the outside of the balance slide bar 5. A displacement bearing frame 6 is connected between the guide rod slide cylinder 51 and the displacement slider 35. A drilling device 8 is fixed to the displacement bearing frame 6 by bolts. The drilling device 8 has a lifting drilling rod 85. When the lifting drilling rod 85 moves downward, it passes through the gap between the displacement bearing frame 6 and the base horizontal frame 1 and can perform drilling operations. In this embodiment, a moving device mounting frame 2 is fixed on the base horizontal frame 1. See [link to relevant documentation]. Figure 1There is no drilling device 8 on the left side of the horizontal base frame 1. The left side of the horizontal base frame 1 is shortened to form a measuring end side. A movable device mounting frame 2 is provided on the right side of the horizontal base frame 1. The drilling device 8 can move on the movable device mounting frame 2 and can be adjusted in distance. When in use, the measuring end side is the position of the previous plant planting hole. By adjusting the displacement of the drilling device 8, the distance between the previous plant spacing hole and the plant planting hole to be drilled this time can be adjusted to achieve the adjustment of the plant spacing. After the adjustment is completed, the plant spacing size is maintained, and the planting holes of the same plant (with the same plant spacing size requirement) are drilled in sequence. In this way, the plant spacing is adjusted and the continuous drilling operation of the same plant is achieved.

[0027] Example 2

[0028] like Figures 1-4 As shown, an adjustable punching device for adjustable plant spacing includes a base horizontal frame 1 and a punching device 8. At least one movable device mounting frame 2 (such as...) is fixed on the base horizontal frame 1. Figure 1 As shown, in this embodiment, two mobile device mounting brackets 2 are fixed on the horizontal base frame 1; of course, this utility model can also fix multiple mobile device mounting brackets 2, for example... Figure 1 There are two mobile device mounting brackets 2, and then in Figure 1 Two mobile device mounting frames 2 are arranged side by side (and more can be added side by side). A displacement driving device 3 is mounted on the mobile device mounting frame 2. The displacement driving device 3 includes a displacement adjusting screw 31 and a screw nut 32 that cooperates with the displacement adjusting screw 31. The displacement adjusting screw 31 is rotatably mounted on the mobile device mounting frame 2, and a wheel 34 is fixed to the outer end of the displacement adjusting screw 31. A displacement slide rail 4 parallel to the displacement adjusting screw 31 is fixed on the base horizontal frame 1 or the mobile device mounting frame 2. A displacement slider 35, linearly sliding at the upper limit of the displacement slide rail 4, is fixed on the screw nut 32. A balance slide rod 5 parallel to the displacement slide rail 4 is fixed on the base horizontal frame 1 or the mobile device mounting frame 2 (preferably, a rod seat 7 corresponding to the balance slide rod 5 is fixed on the base horizontal frame 1 or the mobile device mounting frame 2; see [link]). Figure 1 Two mobile device mounting frames 2 are symmetrically arranged. A balance slide bar 5 is installed on the base horizontal frame 1 and spans the two mobile device mounting frames 2. The balance slide bar 5 is a long bar shared by both mobile device mounting frames 2. A guide rod slide cylinder 51 is slidably fitted on the outside of the balance slide bar 5. A displacement bearing frame 6 is connected between the guide rod slide cylinder 51 and the displacement slider 35. A drilling device 8 is fixed to the displacement bearing frame 6 by bolts. The drilling device 8 has a lifting drilling rod 85 (the drilling device 8 has a drive device to drive the lifting drilling rod 85 to move up and down). When the lifting drilling rod 85 moves down, it passes through the gap between the displacement bearing frame 6 and the base horizontal frame 1 and can perform drilling operations.

[0029] In this embodiment, two mobile device mounting brackets 2 are fixed on the horizontal base frame 1. The two mobile device mounting brackets 2 are symmetrically arranged on the horizontal plane of the horizontal base frame 1. Each mobile device mounting bracket 2 is equipped with a displacement driving device 3 and a drilling device 8 corresponding to the displacement driving device 3 (as opposed to embodiment one, e.g., Figure 1 As shown, in this embodiment, two sets of drilling devices 8 are symmetrically arranged on the left and right sides. The two sets of drilling devices 8 are slidably mounted on two moving device mounting frames 2 and are moved and adjusted by two displacement driving devices 3. The two drilling devices 8 are symmetrically arranged, and the distance between the lifting drilling rods 85 of the two drilling devices 8 is adjustable. Figure 1 As shown, the first side frames 21 of the two mobile device mounting frames 2 are designed to be close to each other, and the second side frames 22 of the two mobile device mounting frames 2 are both located at the far end.

[0030] In some embodiments, the base horizontal frame 1 or the moving device mounting frame 2 is provided with a measuring scale corresponding to the length direction of the displacement adjusting screw 31. The measuring scale is parallel to the length direction of the displacement adjusting screw 31. The screw nut 32 moves linearly on the displacement adjusting screw 31 and can drive the displacement support frame 6 to move linearly. The displacement support frame 6 drives the corresponding drilling device 8 to move, thereby realizing the horizontal movement adjustment of the drilling position, and thus realizing the plant spacing adjustment of the planting holes for the front and rear plant operations. The measuring scale can be used for precise measurement (so as to facilitate recording or precise adjustment and control of the operation).

[0031] In some embodiments, the mobile device mounting frame 2 includes a first side frame 21 and a second side frame 22 parallel to the first side frame 21. Both the first side frame 21 and the second side frame 22 are equipped with bearing seats 33 with bearings, and the end of the displacement adjusting screw 31 is rotatably mounted in the bearing seat 33.

[0032] In some embodiments, the drilling device 8 employs a motor-driven lifting drilling rod 85 for reciprocating lifting motion. The drilling device 8 includes a mounting plate 81, a motor 88, a drilling screw 82, and a drilling screw slider 83. The bottom of the mounting plate 81 is fixed to the displacement support frame 6. An end seat 87 is fixed to the top side of the mounting plate 81, and the motor 88 is fixed to the bottom side of the mounting plate 81. The power output shaft of the motor 88 is poweredly connected to the drilling screw 82. The top of the drilling screw 82 is rotatably mounted on the end seat 87. A drilling screw slider 83, which constrains the lifting motion, is mounted on the drilling screw 82. The drilling screw slider 83 has a screw nut hole that mates with the drilling screw 82. The top of the lifting drilling rod 85 is fixed to the drilling screw slider 83. At least one guide rod 86 parallel to the drilling screw 82 is fixed to the end seat 87. The drilling screw slider 83 has a guide rod hole that slides through and constrains the guide rod 86. The bottom end of the guide rod 86 has a stop block 861. The drilling screw slider 83 has a horizontally extending drilling rod mounting arm 831 at its end, and the top of the lifting drilling rod 85 is fixed to the drilling rod mounting arm 831. The power output shaft of the motor 88 is connected to the drilling screw 82 via a coupling 84; the motor 88 moves regularly in both forward and reverse directions, driving the drilling screw slider 83 to move up and down reciprocally, which in turn drives the lifting drilling rod 85 to move up and down reciprocally, thereby realizing the drilling reciprocating operation. In some embodiments, the drilling device 8 can also be a lifting cylinder, which drives the lifting drilling rod 85 to move up and down reciprocally, thereby realizing the drilling reciprocating operation. Of course, other lifting reciprocating motion power devices can also be used; a combination drive form of motor driving cam rotation can also be used, where the cam drives the lifting drilling rod 85 to move up and down reciprocally.

[0033] When using, such as Figure 1 As shown, the left and right punching devices 8 are respectively mounted on their corresponding displacement support frames 6. The displacement support frames 6 are driven to move by the corresponding displacement driving device 3, thereby adjusting the punching distance of the planting holes of the left and right punching devices 8, and thus adjusting the plant spacing. After adjustment, the plant spacing is maintained, and the same plant (with the same spacing requirement) is continuously punched sequentially. This achieves plant spacing adjustment and continuous punching of the same plant. A prototype of the adjustable punching device according to this utility model is manufactured, and a walking frame (including walking tires and a motor to drive the tires) is loaded at the bottom of the prototype. The walking frame moves (the walking distance can be set to be synchronized with the plant spacing), allowing the adjustable punching device to perform continuous punching operations. A prototype of the adjustable punching device of this utility model is manufactured, and a walking frame (including walking tires and a motor that drives the tires to move) is loaded at the bottom of the prototype. The position of the displacement support frame 6 is adjusted by the wheel 34, so that the distance between the front and rear displacement support frames 6 can be adjusted, thereby realizing the plant spacing adjustment.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
