Description

Technical Field

[0001] This utility model relates to the field of forestry processing technology, specifically a rattan clamping and cutting device for forestry. Background Technology

[0002] Rattan is a natural woven material made from the stems of vine plants, also known as rattan strips. It is characterized by its long, tough, smooth surface and excellent elasticity. Rattan occupies an inferior ecological niche in forests and, when exposed to a lot of sunlight, it grows and reproduces rapidly and covers a wide area, thus affecting the growth of other trees.

[0003] Chinese invention patent CN116214652A, published on June 6, 2023, discloses a clamping and cutting device for forestry rattan, including a movable square tube, a slider groove, a limiting slider, a clamping unit, and a cutting unit. The movable square tube has a slider groove; a limiting slider is inserted into the slider groove; a first fastener is threaded into the limiting slider; a first adjusting groove is provided on the movable square tube corresponding to the first fastener. Through the cooperation of the cutting unit and the clamping unit, when cutting a large quantity of rattan, a portion can be clamped before cutting, thus clamping the cut rattan. This allows the movable square tube to be rotated to transfer the cut rattan, separating the uncut and cut rattan. This facilitates precise and efficient cutting of the uncut rattan, solving the problem of existing reciprocating cutting devices failing to transfer rattan promptly after cutting, resulting in unclear cutting boundaries and wasted labor and reduced efficiency due to recutting already cut rattan.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: Although the existing cutting devices are lightweight and miniaturized, making them easy to hold, move, and insert into the rattan for cutting, when moving the rattan after cutting, the arm needs to exert force to overcome the weight of the rattan or the friction between the rattan and the ground. This means that the force required to move the rattan is greater than the force required to cut the rattan, resulting in the rattan transfer work still being laborious. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that while existing cutting devices are lightweight and compact, making them easy to hold, move, and insert into rattan for cutting, they require arm strength to overcome the weight of the rattan or the friction between the rattan and the ground when moving them after cutting. This means that the force required to move the rattan is greater than the force required to cut it, resulting in the rattan transfer work still being laborious. This invention provides a rattan clamping and cutting device for forestry.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention relates to a rattan clamping and cutting device for forestry, comprising a Y-shaped frame; a plurality of rollers are fixedly connected to the lower surface of the Y-shaped frame; blade grooves are symmetrically formed inside the Y-shaped frame; a cutting blade is detachably fixedly connected to the blade groove; a positioning shaft is fixedly connected to the upper surface of the Y-shaped frame; a clamping cover and a clamping plate are slidably sleeved on the outer surface of the positioning shaft; a central groove is formed inside the clamping cover corresponding to the clamping plate; and a second fastener is threadedly connected to the clamping cover through an opening.

[0008] Furthermore, one end of the Y-shaped frame is provided with a clearance groove; a push rod is connected to the clearance groove by a pin.

[0009] Furthermore, a handle groove is provided at the upper end of the push rod.

[0010] The forestry rattan clamping and cutting device provided by this utility model has the following beneficial effects:

[0011] 1. This utility model uses a movable Y-shaped frame to align the opening and the cutting blade with the root system of the vine. Then, the clamping cover and clamping plate are pushed closer together to clamp the vine. Tools or ropes are used to fix the vine between the clamping cover and clamping plate. Then, the Y-shaped frame is pushed forward so that the cutting blade cuts the root system of the vine. Then, the positioning shaft is pulled backward, moving a large number of vines with cut roots. The weight of the vine is borne by rollers, and the friction of the movement is reduced by the rolling friction of the rollers, thus making the movement of the vine more labor-saving and efficient.

[0012] 2. This utility model allows for pushing and pulling by hand using a push rod, enabling the Y-shaped frame and rollers to move back and forth linearly on the ground. This allows the rod to be inserted into the lower part of the rattan, where the cutting blade contacts the rattan to complete the cutting. The upper end of the rattan is then clamped and fixed by the clamping cover and clamping plate. The Y-shaped frame is then pulled to the location where the rattan is stacked for centralized collection. Thus, during the movement of a large number of rattan, the rollers bear the weight of the rattan, and the rolling friction reduces the resistance to movement, making the cutting and transfer process more labor-saving and efficient.

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please see Figure 1-3 As shown, a forestry rattan clamping and cutting device includes a metal Y-frame 1; multiple rollers 4 are fixedly connected to the lower surface of the Y-frame 1; blade slots 2 are symmetrically formed inside the Y-frame 1; metal cutting blades 3 are detachably fixed to the blade slots 2 by bolts; a positioning shaft 8 is fixedly connected to the upper surface of the Y-frame 1; a clamping cover 9 and a clamping plate 11 are slidably sleeved on the outer surface of the positioning shaft 8; a central groove 10 is formed inside the clamping cover 9 corresponding to the clamping plate 11; a second fastener 16 is threadedly connected to the clamping cover 9 through an opening. In use, the device can be moved... The Y-shaped frame 1 aligns the opening and the cutting blade 3 with the roots of the vine. Then, the clamping cover 9 and the clamping plate 11 are pushed closer together to clamp the vine. The vine is secured between the clamping cover 9 and the clamping plate 11 using tools or ropes. The Y-shaped frame 1 is then pushed forward, causing the cutting blade 3 to cut the roots of the vine. The positioning shaft 8 is then pulled backward, moving the vine with a large amount of roots cut off. The weight of the vine is supported by the rollers 4, and the rolling friction of the rollers 4 reduces the friction of movement, making the movement of the vine more labor-saving and efficient.

[0022] One end of the Y-shaped frame 1 has an avoidance groove 5; a push rod 6 is connected to the inside of the avoidance groove 5. By holding the push rod 6 by hand, the Y-shaped frame 1 and the roller 4 can move back and forth in a straight line on the ground, so that it can be inserted into the lower position of the rattan. The cutting blade 3 contacts the rattan to complete the cutting. Then the upper end of the rattan is clamped and fixed by the clamping cover 9 and the clamping plate 11. Then the Y-shaped frame 1 is pulled to the position where the rattan is piled up and collected. In the process of moving a large number of rattan, the roller 4 bears the weight of the rattan, and the rolling friction reduces the resistance to movement, making the cutting and transfer process more labor-saving and efficient.

[0023] The upper end of the push rod 6 is provided with a handle groove 7. By inserting the palm into the handle groove 7 to hold the push rod 6, it is convenient to hold and fix it and to push and pull with force.

[0024] Multiple array shafts 12 are inserted into the openings on the clamping cover 9 and the clamping plate 11. The multiple array shafts 12 increase the contact area with the rattan, so that sufficient friction can be generated to fix the rattan when clamping a large number of rattan.

[0025] An elastic element 13 is fixedly connected between the clamping cover 9 and the clamping plate 11. The elastic element 13 allows the clamping cover 9 and the clamping plate 11 to maintain an open angle when there is no external force, thus facilitating the closing and clamping of the rattan to complete the fixation.

[0026] The clamping cover 9 and the clamping plate 11 are threaded with a first fastener 14; a woven strap 15 is sleeved on the first fastener 14. By manually holding and pulling the woven strap 15, the clamping cover 9 and the clamping plate 11 are brought closer to each other, thereby clamping the rattan and completing the fixing action. Then the woven strap 15 is released, and the clamping cover 9 and the clamping plate 11 open under the elastic force of the elastic member 13, releasing the rattan. Then the rattan is released from the clamping cover 9 and the clamping plate 11 by manual or gravity.
