Abstract
Description
Technical Field
[0001] This utility model relates to a tobacco field film breaker, belonging to the field of tobacco field transplanting film breaker technology. Background Technology
[0002] In tobacco cultivation, transplanting tobacco plants through wells and pits has become an important method for planting tobacco in high-altitude, relatively low-temperature areas unsuitable for transplanting. The use of wells and pits, along with plastic film, is a crucial part of this method, effectively protecting seedlings from heat and moisture loss and preventing nutrient loss. The plastic film often needs to be broken before transplanting.
[0003] Existing literature (CN221382299U) discloses a tobacco field film-breaking and pesticide-applying device, which includes: a film-breaking unit comprising an operating rod and a film-breaking cylinder, the film-breaking cylinder being disposed at the bottom of the operating rod; and a pesticide-applying unit comprising a pesticide tank and a soil-breaking water-injection gun, the soil-breaking water-injection gun comprising a gun housing, a gun head, and a first spring, the gun housing being disposed at the inner top of the film-breaking cylinder, the top of the gun housing being connected to the pesticide tank via a water supply pipe, the bottom of the gun head extending a predetermined distance beyond the bottom of the film-breaking cylinder, the gun head being retractably and movably disposed within the gun housing, and the first spring being disposed between the top of the gun head and the inner top of the gun housing. Although this scheme can simultaneously apply pesticides during film breaking to prevent weed growth, the residual film still remains on the ridges, causing environmental pollution and affecting the effectiveness of pesticide application. Utility Model Content
[0004] Based on the above, this utility model provides a tobacco film breaker to overcome the shortcomings of the prior art.
[0005] The technical solution of this utility model is: a tobacco film breaker, comprising:
[0006] The membrane breaking unit includes an operating rod, a membrane breaking cylinder installed at the bottom of the operating rod, a pressing rod movably fitted inside the operating rod, and a return spring installed between the top of the pressing rod and the top of the operating rod. The bottom of the pressing rod extends downward into the membrane breaking cylinder, and the bottom of the pressing rod is provided with barbs.
[0007] The application unit includes an application pipe arranged circumferentially along the inner wall of the film-breaking cylinder, a spray nozzle disposed on the application pipe, a delivery pipe connected to the application pipe, and a medicine tank connected to the delivery pipe. The spray nozzle is inclined downward from the inner wall of the film-breaking cylinder to its center.
[0008] In one example, it also includes: a distance unit, comprising a distance rod and a marker rod, the distance rod being horizontally disposed on the side of the film-breaking cylinder, the marker rod being slidably and adjustablely mounted on the distance rod, and the bottom of the marker rod being at least flush with the bottom of the film-breaking cylinder.
[0009] In one example, a film-fixing rod is also included, which is disposed on the top surface inside the film-breaking cylinder and is arranged adjacent to the pressing rod.
[0010] In one example, the medicine tank is a backpack electric septic tank, which includes a storage tank, an electric pump, and a carrying strap. The carrying strap is connected to the storage tank, the electric pump is located inside the storage tank, and one end of the delivery pipe is connected to the outlet of the electric pump.
[0011] The beneficial effects of this utility model are as follows: Through the combination of the barbed structure at the bottom of the pressing rod and the return spring, after the film is broken, the pressing rod moves down to pierce the residual film. When returning to its original position, it drives the residual film to detach from the ground. Combined with the secondary fixation of the residual film by the film fixing rod, it effectively avoids the residual film remaining in the soil, significantly reducing the risk of environmental pollution. The spray nozzle of the application unit is set circumferentially along the inner wall of the film breaking cylinder. After breaking the film and collecting the residual film, the pesticide can be directly and evenly sprayed onto the film breaking area, realizing the integrated operation of film breaking and pesticide application. This not only inhibits weed growth but also reduces repetitive manual operations, greatly improving field management efficiency. Through the above structure, this utility model effectively solves the pain points of residual film pollution and poor pesticide application effect of traditional film breaking devices, and is both environmentally friendly and practical.

[0019] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0020] Please see Figures 1 to 3 This embodiment provides a film-breaking device for tobacco fields, which includes a film-breaking unit and a pesticide application unit.
[0021] The film-breaking unit includes an operating rod 11, a film-breaking cylinder 12 installed at the bottom of the operating rod 11, a pressing rod 13 movably fitted inside the operating rod 11, and a return spring 14 installed between the top of the pressing rod 13 and the top of the operating rod 11. In its natural state, the return spring 14 drives the pressing rod 13 to move upward, and the bottom of the pressing rod 13 extends downward into the film-breaking cylinder 12. The bottom of the pressing rod 13 is provided with barbs 15, which are multiple pointed rods spaced at an angle and inclinedly arranged at the end of the pressing rod 13. After the film-breaking cylinder 12 completes the film breaking, the pressing rod 13 is pushed downward. At this time, the return spring 14 is under force, and the pressing rod 13 moves downward. Its bottom barbs 15 pass through the residual film. As the pressing rod 13 is no longer under force, the return spring 14 drives the pressing rod 13 to move upward, and the barbs 15 drive the residual film to detach from the ground, thereby realizing the collection of the residual film.
[0022] The application form includes an application pipe 21 installed circumferentially along the inner wall of the film-breaking cylinder 12, spray nozzles 22 spaced apart on the application pipe 21, a delivery pipe 23 connected to the application pipe 21, and a pesticide tank 24 connected to the delivery pipe 23. The spray nozzles 22 are inclined downward from the inner wall of the film-breaking cylinder 12 to its center, so that after the film breaks, the pesticide can be sprayed evenly onto the ground at the film-breaking point simultaneously through the spray nozzles 22, improving the accuracy of the application and avoiding pesticide waste.
[0023] For ease of operation, this film rupture device also includes a distance fixing unit, including a distance fixing rod 31 and a marking rod 32. The distance fixing rod 31 is horizontally installed on the side of the film rupture cylinder 12, and the end of the distance fixing rod 31 can be fixed on the side of the film rupture cylinder 12 or the operating rod 11. The marking rod 32 is slidably and adjustablely installed on the distance fixing rod 31, and the bottom of the marking rod 32 is at least flush with the bottom of the film rupture cylinder 12. Thus, when rupturing the film, the marking rod 32 can simultaneously mark the next film rupture position on the film, facilitating subsequent rapid positioning operations.
[0024] For ease of operation, this film breaking device also includes film fixing rods 16 arranged on the top surface of the film breaking cylinder 12. Multiple film fixing rods 16 are arranged adjacent to the pressing rod 13. When the barbs 15 move the residual film upward, the residual film passes through the film fixing rods 16 for further fixation, which can effectively prevent it from falling into the soil.
[0025] For ease of operation, the water tank 24 is a backpack electric water and fertilizer device. The backpack electric water and fertilizer device includes a storage tank 241, an electric pump and a carrying strap 242. The two carrying straps 242 are connected to the storage tank 241. The electric pump is installed inside the storage tank 241, and one end of the delivery pipe 23 is connected to the outlet of the electric pump. The other end extends out of the storage tank 241 and is fixed to the operating rod 11.
[0026] The working principle of the above-mentioned tobacco film breaker is as follows:
[0027] First, start the backpack electric water and fertilizer device, lift the operating lever 11 and position the film-breaking cylinder 12 above the film-breaking position on the ground to be smoked, then insert the film-breaking cylinder 12 downwards onto the mulch film. At this time, the mulch film is cut off. Then push the pressing rod 13 downwards. The barbs 15 on the pressing rod 13 pass through the mulch film. After releasing, the return spring 14 drives the pressing rod 13 to move upwards away from the ground. When moving upwards, the residual film passes through the film-fixing rod 16 and is further fixed. Then start the electric pump so that the herbicide is sprayed onto the soil surface through the spray nozzle 22.
[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
