Description

Technical Field

[0001] This utility model relates to the field of agricultural production equipment technology, specifically to an agricultural film punch. Background Technology

[0002] Agricultural plastic film plays several important roles in agricultural production, including: Heat preservation: Agricultural plastic film effectively reduces heat loss from the soil and plant surfaces, especially during cold seasons or at night, maintaining soil and plant temperatures and creating a relatively warm microclimate conducive to crop growth and development. Moisture retention: The film blocks external moisture evaporation, maintaining soil moisture, reducing irrigation frequency, and conserving water resources. Windbreak and soil stabilization: In windy weather, agricultural plastic film reduces wind erosion of the soil, preventing soil from being blown away and maintaining soil fertility and structural stability. It also reduces direct wind exposure to crops, protecting them from mechanical damage. Pest and disease control: Some special types of agricultural plastic film, such as those containing insecticides, can directly prevent pest invasion, reducing pesticide use, lowering agricultural production costs, and also contributing to environmental protection. Early or delayed harvest: By covering crops with agricultural plastic film, the growth cycle can be regulated, allowing crops to grow normally even under unfavorable climatic conditions, thus achieving the goal of early or delayed harvest. Improving the soil environment: Agricultural film can also improve the soil environment to a certain extent, such as increasing soil temperature and promoting the activity of soil microorganisms, which is beneficial to crop root growth and nutrient absorption and utilization. Weed control: Black or dark-colored agricultural film can block sunlight, inhibit weed growth, reduce competition between weeds and crops, and improve crop yield and quality.

[0003] Farmers traditionally tear open the plastic film by hand to expose the crop planting area, a method that is inefficient. Application number 2017208230072 discloses a plastic film punch, specifically a punch comprising a hollow, one-end-opening film-breaking cylinder. The end of the film-breaking cylinder facing away from the opening has an operating handle for easy application of force by the user. It also includes a measuring device for measuring plant spacing; the measuring device includes a measuring rod for measuring plant spacing and a fixing mechanism for fixing the measuring rod; the measuring rod is located at the end of the film-breaking cylinder facing away from the opening. This invention has the advantages of convenient punching and facilitating farmers' determination of the crop planting location.

[0004] Although the above technical solutions have improved planting efficiency, they still have the following drawbacks: 1. The operation is not convenient enough. Farmers need to use the previous drilling point as a reference when drilling holes, which is complicated and reduces drilling efficiency; 2. The ergonomics need to be improved. The process is not labor-saving enough. The film needs to be manually pressed down to make holes, which consumes too much physical strength when performing a large number of repetitive tasks. Utility Model Content

[0005] This invention proposes an agricultural film puncher that solves the problems of complex operation and poor ergonomics of existing agricultural film punchers.

[0006] The technical solution of this utility model is as follows: an agricultural film puncher, including a rotating shaft, a bearing, a conical support, a punching cone, a rotating shaft fixing block, adjustable casters, a handrail support, and a handrail. The conical support has a ring-shaped structure with several threaded holes evenly distributed in the radial direction. One end of the punching cone is connected to a screw, and the punching cone is detachably connected to the conical support via the screw. The center of the conical support has a shaft hole, and a rotating shaft is located inside the shaft hole. Rotating shaft fixing blocks are rotatably connected to both ends of the rotating shaft. A bearing is located between the rotating shaft fixing block and the rotating shaft. The bottom of the rotating shaft fixing block has an oblong hole, and the adjustable casters can slide and lock within the oblong hole. A handrail support is located between the rotating shaft fixing blocks, and a handrail is located on the handrail support.

[0007] Preferably, the adjustable caster consists of a connecting rod, a caster frame, a swivel nut, a boss, and a caster. One end of the connecting rod is a screw, and the other end is an internal thread. The screw has a swivel nut, and the top of the swivel nut is a flange. The boss is connected to the screw of the connecting rod through the internal thread. The caster frame has a caster at the bottom and a screw at the top, which is connected to the internal thread at the bottom of the connecting rod.

[0008] Preferably, the handrail support is in the shape of a right trapezoid, and the two sides are detachably connected to the pivot fixing block.

[0009] Preferably, the handrail is located on the upper base of a right-angled trapezoid and is vertically connected to the upper base, and the angle between the handrail axis and the horizontal plane is 60°.

[0010] Preferably, the outer edge of the handrail has a rubber anti-slip sleeve.

[0011] Preferably, the outer edge of the punching cone is evenly distributed with several grooves.

[0012] Preferably, the rotating shaft fixing block is made of aluminum alloy profile.

[0013] Preferably, the cone-shaped support is made of rolled steel strip.

[0014] The principle of this invention: To solve the problems of complex operation and poor ergonomics of existing film punchers, this invention adopts the following technical solution: A circular cone-shaped support is used for rolling punching. When the cone-shaped support rotates, the punching cone mounted on it pierces the film to complete the punching. Farmers only need to hold the handle firmly, push or drag the support, and control the direction of the cone-shaped support to rotate and perform the punching operation. This solution can further improve punching efficiency, consume less physical strength, and is more relaxing to use, with excellent ergonomics. When it is necessary to adjust the punching distance, the cone-shaped support can be selected... The frame features various combinations of threaded holes to adjust the drilling distance. The drilling distance can also be further adjusted by rotating the threaded connection between the drilling cone screw and the cone support. These two methods provide a wide range of adjustable drilling distances and strong adaptability. When drilling holes in agricultural film on single ridges, the adjustable casters at both ends of the shaft rest within the furrow, providing auxiliary support and reducing the physical strain on farmers lifting the support frame. This further improves ergonomics, giving farmers a better operating experience and increasing drilling efficiency. The adjustable casters can slide and lock within the oblong holes at the bottom of the shaft fixing block, adapting to single ridges of different widths and further enhancing the adaptability of the puncher.

[0015] The beneficial effects of this utility model are as follows: An agricultural film puncher is easy to operate, requires less physical effort to use, has excellent ergonomics, is highly adaptable, and has high punching efficiency, which helps to improve agricultural production efficiency.

Detailed Implementation

[0020] The specific implementation method of this utility model is as follows: Figure 1 , Figure 2 , Figure 3As shown, an agricultural film perforator includes a rotating shaft 104, a bearing 106, a conical support 101, a perforating cone 103, a rotating shaft fixing block 105, adjustable casters 108, a handrail support 109, and a handrail 110. The conical support 101 has a ring-shaped structure with several threaded holes 102 evenly distributed in the radial direction. One end of the perforating cone 103 is connected to a screw, and the perforating cone 103 is detachably connected to the conical support 101 via the screw. The cone head support 101 has a shaft hole at its center, and a rotating shaft 104 is located inside the shaft hole. The two ends of the rotating shaft 104 are rotatably connected to rotating shaft fixing blocks 105. There is a bearing 106 between the rotating shaft fixing blocks 105 and the rotating shaft 104. The bottom of the rotating shaft fixing blocks 105 has an oblong hole 107. The adjustable caster 108 can slide and lock in the oblong hole 107. There is a handrail support 109 between the rotating shaft fixing blocks 105, and a handrail 110 is on the handrail support 109. In this embodiment, the farmer pushes the cone support 101 to rotate via the handrail bracket 109. The punching cone 103 on the cone support 101 pierces the film to complete the punching, which consumes less physical strength and has a high punching efficiency. When it is necessary to adjust the punching distance, different combinations of threaded holes 102 on the cone support 101 can be selected to obtain various punching distance adjustments. Alternatively, the length of the connection between the screw of the punching cone 103 and the threaded hole 102 of the cone support 101 can be rotated to achieve further adjustment of the punching distance. This method is highly adaptable. In addition, when punching holes at the top of a single ridge, the adjustable casters 108 on both sides of the rotating shaft 104 provide certain auxiliary support, reducing the difficulty of controlling the movement direction of the cone support 101 and improving punching efficiency, which helps to improve agricultural production efficiency.

[0021] Specifically, such as Figure 3 As shown, the adjustable caster 108 consists of a connecting rod 1081, a caster frame 1082, a nut 1083, a boss 1084, and a caster 1085. One end of the connecting rod 1081 is a screw, and the other end is an internal thread. The screw has a nut 1083 on it, and the top of the nut 1083 is a flange. The boss 1084 is connected to the screw of the connecting rod 1081 through an internal thread. The caster frame 1082 has a caster 1085 at the bottom and a screw at the top, which is connected to the internal thread at the bottom of the connecting rod 1081. In this embodiment, the connection length between the connecting rod 1081 and the caster frame 1082 can be adjusted to accommodate single ridges of different heights. When it is necessary to adjust the distance between the adjustable casters 108, the plum nut 1083 needs to be rotated to disengage it from the bottom surface of the pivot fixing block 105. After moving the connecting rod 1081 to the appropriate position, the plum nut 1083 can be locked to accommodate single ridges of different widths. Of course, the casters 1085 should be selected to be models that are not easy to sink or slip in the furrow.

[0022] Specifically, such as Figure 1 , Figure 2As shown, the handrail bracket 109 is a right-angled trapezoid, with its two sides detachably connected to the pivot fixing block 105. In this embodiment, when working on a single ridge, farmers can stand within the furrow to move around, making the operation more convenient.

[0023] Specifically, such as Figure 1 , Figure 2 As shown, the armrest 110 is located on the upper base of a right-angled trapezoid and is vertically connected to the upper base. The angle between the axis of the armrest 110 and the horizontal plane is 60°. In this embodiment, the axis of the armrest 110 forms a certain angle with the horizontal plane, which not only makes it easier for the user to grip the armrest 110, but also makes the force applied by the user to the armrest support 109 more concentrated, reducing wrist fatigue.

[0024] Specifically, the outer edge of the handrail 110 is covered with a rubber anti-slip sleeve. In this embodiment, the rubber anti-slip sleeve makes it less likely to slip when gripped in a wet environment.

[0025] Specifically, such as Figure 1 , Figure 2 As shown, the outer edge of the punching cone 103 is evenly distributed with several grooves. In this embodiment, the grooves can resolve the air pressure difference between the top and bottom of the film, preventing the film from moving when the punching cone 103 is raised, thus avoiding tearing of the film.

[0026] Specifically, the pivot fixing block 105 is made of aluminum alloy profile. In this embodiment, the pivot fixing block 105 made of aluminum alloy profile is lightweight, has high structural strength, and a long service life.

[0027] Specifically, the cone-shaped support 101 is made of rolled steel strip. In this embodiment, the cone-shaped support 101 made of rolled steel strip has a moderate weight, which makes it easy for the punching cone 103 to pierce the film, improves the punching efficiency, is easy to obtain materials, and reduces the production cost of the punch.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
