Description

Technical Field

[0001] The utility model belongs to the technical field of bamboo felling, and in particular relates to a bamboo felling device. Background Art

[0002] Bamboo, also known as bamboo, is a perennial herbaceous plant of the Gramineae family and the genus Bambusa. Most of the stems are woody, slightly hollow in the middle, with many and dense nodes, growing rapidly, usually 5-10 meters high, with a wide variety of species, and widely distributed in tropical, subtropical and temperate regions. As we all know, bamboo utilization has broken through the traditional field and has been widely used in construction, papermaking, light industry and other industries, so the market demand for bamboo is increasing day by day.

[0003] In my country, bamboos mostly grow in hilly and mountainous areas. Large and medium-sized bamboo felling machinery and equipment are almost unavailable. Bamboo felling is mainly done by hand-held machetes, which not only has the problems of high labor intensity and low efficiency, but also uneven cuts. Some areas use small portable oil saws, electric shears and other felling equipment to replace machetes for felling. Although it overcomes the disadvantages of hand-held machetes for felling, workers are required to hold the equipment and bend over to work, which can easily cause lumbar muscle strain and lumbar disc herniation. Therefore, it is particularly necessary to provide a new type of bamboo felling device to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a bamboo felling device, which is easy to carry and can be used for felling bamboo. Workers do not need to bend over to work, which saves time and effort, and can cut a smooth incision, thereby overcoming the shortcomings of the prior art.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a bamboo felling device, which includes a backpack power device, a mounting frame and a hand-held rod arranged on the mounting frame, two shearing blades are hinged at the front end of the mounting frame, and an arm rod is fixedly connected to the rear end of each shearing blade, and the two arm rods are respectively located on both sides of the mounting frame, and the free ends of the two arm rods are connected by an elastic member. A rotating shaft is provided at the rear end of the mounting frame, and the rotating shaft is connected to the output end of the backpack power device through a soft shaft. A cam is fixedly mounted on the rotating shaft, and the opposite sides of the cam are respectively abutted against the two arm rods.

[0006] The above-mentioned bamboo felling device is characterized in that the hand-held rod is tilted backward relative to the top surface of the mounting frame. With such a structural arrangement, when felling bamboo, the distance between the hand-held portion of the hand-held rod and the bamboo to be felled is large enough, which effectively avoids the hand holding the hand-held rod from contacting the bamboo to be felled, making it convenient for workers to perform bamboo felling operations.

[0007] The bamboo felling device is characterized in that the two shear blades can form a shear ring surrounding the bamboo. Such a structural arrangement can ensure that the bamboo to be felled is completely cut off when felling the bamboo.

[0008] The above-mentioned bamboo felling device is characterized in that the elastic member is an elastic rope or a spring.

[0009] The above-mentioned bamboo felling device is characterized in that the cam is an elliptical cam.

[0010] The above-mentioned bamboo felling device is that the backpack power device includes a back box and a drive motor and a battery arranged in the back box, the drive motor is electrically connected to the battery, and the output end of the drive motor is connected to the rotating shaft through a flexible shaft.

[0011] The bamboo felling device is provided with a remote controller for controlling the operation of the driving motor on the hand-held rod.

[0012] Compared with the prior art, the beneficial effect of the utility model is as follows: when felling bamboo, hold the hand-held rod so that the two shear blades are located at the bamboo to be cut, and by controlling the operation of the backpack power device, the backpack power device drives the cam to rotate through the flexible shaft and the rotating shaft in turn, and the two arm rods are spread apart by the cam, so that the free ends of the two arm rods are separated from each other, so that the two shear blades can realize the shearing function under the drive of the two arm rods, cut the bamboo, and achieve the purpose of felling bamboo. With the bamboo felling device of the utility model, workers only need to stand and hold the hand-held rod with less force to cut the bamboo, without bending over and arching their backs to work, and the labor intensity is low, which can significantly improve the efficiency of bamboo felling. With the bamboo felling device of the utility model, the free ends of the two arm rods are pulled by elastic members, so that the two shear blades form a shearing opening when the bamboo is not cut, and the opening is used to facilitate the bamboo to be cut between the two shear blades, thereby improving the efficiency of bamboo felling. In addition, the bamboo felling device of the utility model has the advantages of clever design, convenient carrying and smooth felling incision. BRIEF DESCRIPTION OF THE DRAWINGS
