Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to tobacco planting technical field, concretely relates to a bottom leaf shears. BACKGROUND
[0002] In order to optimize the growth environment of tobacco plant, improve the quality and yield of tobacco leaf, farmers need to remove the bottom leaves and lower leaves without baking value when tobacco leaf grows to the later stage. This link seems simple, but actually consumes a lot of manpower and material resources, especially in the traditional agricultural operation mode, which becomes a big burden for tobacco farmers.
[0003] In the traditional operation, since the tobacco plant is usually tall and straight, the lower area is often poorly ventilated and insufficient in light, forming a relatively poor working environment. Workers have to crawl in the tobacco field in order to knock off these useless tobacco leaves, which not only greatly increases the labor intensity, but also easily causes various occupational diseases by maintaining this posture for a long time. In addition, with the acceleration of urbanization, a large number of rural young labor force flows out, leading to the increasingly prominent problem of difficulty in hiring workers, which makes the cost of tobacco planting continue to rise.
[0004] In the face of this dilemma, tobacco farmers urgently need a farm tool that can reduce labor intensity and improve work efficiency. In this background, the bottom leaf shear technology emerges as the times require. The emergence of this technology not only changes the crawling work mode required by traditional bottom leaf removal, but also greatly improves the work efficiency and reduces the labor cost. UTILITARY MODEL CONTENT
[0005] To solve the above problems, the utility model provides a bottom leaf shear for reducing the labor intensity in the process of knocking off the bottom leaves of tobacco plants.

[0007] Further, the end of the clamping piece away from the handle is integrally formed with a baffle.
[0008] Further, the baffle is arc-shaped.
[0009] Further, the handle comprises an outer tube, an inner rod is slidably fitted in the outer tube, and a plug valve is communicated with the outer tube.

In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0021] The specific implementation process is as follows:
[0022] Embodiment 1:
[0023] As shown in the accompanying Figure 1 - accompanying Figure 3 : a bottom leaf shear, including handle 2, the handle 2 is provided with the clamping piece 1 of symmetrical arrangement at either end, the angle between the axis of handle 2 and the plane where the clamping piece 1 is obtuse, the clamping piece 1 is arc-shaped, the end away from the handle 2 of the clamping piece 1 is integrally formed with the baffle 11, the baffle 11 is arc-shaped, any clamping piece 1 is hinged with the handle 2, and the clamping piece 1 is welded and fixed with the tension spring 3, the other end of the tension spring 3 is welded and fixed with the handle 2, and the other clamping piece 1 is welded and fixed with the handle 2.
[0024] The specific implementation process is as follows:
[0025] Subsequently, the operator selects the position to start the bottom leaf according to the growth of the tobacco plant, and pushes the handle 2 from the position, so that the side wall of the clamping piece 1 peels the bottom leaf of the tobacco plant from the tobacco stem, and after the bottom leaf is pulled to the appropriate extent, the operator reverses the handle 2, and the reaction force of the tobacco stem on the clamping piece 1 drives the clamping piece 1 to rotate again and pull the tension spring 3, and when the clamping piece 1 is separated from the tobacco stem, the tension spring 3 rebounds to reset the clamping piece 1, completing a tobacco bottom leaf operation.
[0026] After the tobacco plant is finished, the operator rotates the handle 2 so that the end of the clamping piece 1 away from the handle 2 contacts the ground, and then moves the handle 2 outward, and moves the bottom leaf under the tobacco plant back and forth along a straight line or a curve, thereby raking the bottom leaf under the tobacco plant.
[0027] And the design of the arc-shaped baffle 11 in the scheme can increase the release area when the device contacts the tobacco stem, avoiding damage to the tobacco stem.
[0028] Example 2:
[0029] As shown in the accompanying Figure 3 , the difference from example 1 is that the handle 2 includes an outer tube 21, the inner rod 22 is slidably connected in the outer tube 21, the outer tube 21 is connected with a stop valve (not shown in the figure), the spring 23 is arranged in the outer tube 21, one end of the spring 23 is welded and fixed with the inner wall of the outer tube 21, and the other end of the spring 23 is welded and fixed with the end of the inner rod 22 close to the outer tube 21.
[0030] The specific implementation process is as follows: in the process of using the device, in the initial state, open the stop valve, pull the inner rod 22 away from the outer tube 21, and air enters the outer tube 21 through the stop valve, when the handle 2 is in the maximum length state, close the stop valve, and the length of the handle 2 is fixed under the action of air pressure, then the operator adjusts the relative position of the inner rod 22 and the outer tube 21 according to his own height and the specific state of the working environment, opens the stop valve again, when the inner rod 22 moves towards the inside of the outer tube 21, the gas in the outer tube 21 leaves the outer tube 21 through the stop valve, and closes the stop valve when the length of the handle 2 is adjusted to the appropriate length.
[0031] Compared with the prior art, the design of the outer tube 21 and the inner rod 22 can help the operator to adjust according to his own height and the working environment, improve the use experience of the device, and the design of the gas in the outer tube 21 can compress the gas in the outer tube 21 when the clamping piece 1 touches the tobacco stem, so as to achieve a certain buffering effect, avoiding damage to the tobacco stem due to improper force during use.
[0032] The spring 23 in the device is designed, after the use of the device is completed, only the user opens the plug valve, under the action of the elasticity of the spring 23, the inner rod 22 can realize the quick reset, which is helpful to reduce the operation steps of the device, and in the process of the bottoming leaf, the spring 23 can further absorb the kinetic energy of the cigarette rod transmitted to the device, so as to further buffer the impact of the device on the cigarette rod.
[0033] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation to the embodiments. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and can not be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
