Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts also belong to the scope of protection of the present application.

[0031] As Figures 1-4 shown, a tree branch cutting machine disclosed in the present application includes a frame 1. A working platform 2 is provided above the frame 1. One end of the frame 1 is provided with a mounting bracket 3 and a guiding bracket 4 respectively along its width direction. A cutting blade 5 is provided between the guiding bracket 4 and the mounting bracket 3. One end of the cutting blade 5 is hinged to the mounting bracket 3, and the other end of the cutting blade 5 is inserted into the guiding bracket 4 and is movably connected to the guiding bracket 4 in the vertical direction. The side of the cutting blade 5 away from the working platform 2 is hinged to one end of a driving rod 6, and the other end of the driving rod 6 is hinged to one end of a swing rod 7. A driving motor 8 is provided below the working platform 2. The housing of the driving motor 8 is fixedly installed on the frame 1. The output end of the driving motor 8 passes through the front side plate of the frame 1 and is fixedly connected to the end of the swing rod 7 away from the driving rod 6. A tree branch conveying mechanism 9 is provided on the working platform 2. The tree branch conveying mechanism 9 can send the tree branches 14 to be cut towards the cutting blade 5.

[0032] In the above embodiments, the output end of the driving motor 8 of the present application is connected to the cutting blade 5 through the swing rod 7 and the driving rod 6, and the swing rod 7 and the driving rod 6 are also hinged. When the output end of the driving motor 8 rotates, the swing rod 7 will rotate synchronously with the driving motor 8. Since the position of the end of the swing rod 7 far from the output shaft of the driving motor 8 changes in the vertical direction during rotation, and one end of the cutting blade 5 connected to the driving rod 6 is hinged to the mounting bracket 3, the swing rod 7 can cause the cutting blade 5 to swing up and down repeatedly at one end within the guiding bracket 4 through the driving rod 6. In this way, when the driving motor 8 is working, the cutting blade 5 can perform repeated cutting operations at a certain frequency at the end of the working platform 2. Cooperating with the tree branch conveying mechanism 9 provided on the working platform 2 of the present application, the tree branches 14 to be cut can be evenly cut into wooden strips of the length required for cultivating fungi by the cutting blade 5. Compared with the method in the prior art where farmers need to use axes or hacksaws to cut tree branches to obtain wooden strips of the required specifications, the present application is simple and convenient to operate. Since the main labor-intensive work is completed by machines, the working intensity of farmers is greatly reduced, and the production of wooden strips is less affected by the fatigue of farmers, so continuous operation can be carried out, and the efficiency of producing wooden strips is also significantly improved.

[0033] Further, as Figure 1 and Figure 2 shown, the tree branch conveying mechanism 9 includes a through groove 91 opened on the working platform 2, and the axis of the through groove 91 is perpendicular to the plane where the cutting blade 5 is located; a moving slider 92 is provided below the through groove 91 along its length direction, and one side of the moving slider 92 is slidably connected to the working platform 2 along the length direction of the through groove 91 through a strip-shaped guide block 93;

[0034] A plurality of automatic clamping units 94 are equidistantly arranged on the moving slider 92 along its length direction, and all the plurality of automatic clamping units 94 are located within the through groove 91. A power unit 95 is installed in the strip-shaped guide block 93; the power unit 95 can drive the moving slider 92 to move along the length direction of the through groove 91, and the plurality of automatic clamping units 94 can convey the tree branches 14 to be cut towards the cutting blade 5 as the moving slider 92 moves.

[0035] In the above embodiments, the width of the through groove 91 of the present application is smaller than the diameter of the tree branch 14 to be cut. In this way, when the tree branch is placed above the through groove 91, the tree branch will not fall through the through groove 91. The present application is provided with a plurality of automatic clamping units 94 in the through groove 91. After the tree branch 14 to be cut is placed above the through groove 91, the automatic clamping unit 94 can automatically clamp the tree branch 14 to be cut. In this way, after the power unit 95 is started, when the moving slider 92 under the working platform 2 moves in the direction of the cutting blade 5 under the action of the strip-shaped guide block 93, the automatic clamping unit 94 can drive the tree branch 14 to be cut to move together in the direction of the cutting blade 5, so as to realize the function of conveying the tree branch 14 to be cut to the cutting blade 5, and the operation is simple and convenient. In the actual use process, in order to increase the moving range of the moving slider 92, an avoidance groove can be added in the area corresponding to the moving slider 92 and the through groove 91 at the front end of the frame 1. In this way, when the moving slider 92 moves in the direction of the cutting blade 5, a larger conveying range can be obtained.

[0036] Further, as Figure 2 shown, the automatic clamping unit 94 includes a triangular flip plate 941, a rotating shaft 942 and a support rod 943. One of the angles of the triangular flip plate 941 is an obtuse angle, and the obtuse angle area of the triangular flip plate 941 is rotatably connected to the moving slider 92 through the rotating shaft 942;

[0037] When the tree branch 14 to be cut is not placed in the through groove 91, the lower side of one acute angle of the triangular flip plate 941 is placed on the support rod 943 fixedly installed on the moving slider 92, and the other acute angle of the triangular flip plate 941 passes upward through the through groove 91 and is located above the through groove 91.

[0038] In the above embodiments, the weight of one end of the triangular flip plate 941 of the present application placed on the support rod 943 is greater than the weight of the end passing upward through the through groove 91. In this way, in the normal state, when no tree branch is placed above the through groove 91 of the working platform 2, the end with the greater weight of the triangular flip plate 941 is placed on the support rod 943 under the action of gravity, and the end with the smaller weight of the triangular flip plate 941 will be pressed up around the rotating shaft 942, so that this end of the triangular flip plate 941 passes upward through the through groove 91. As Figure 2As shown, when the farmer places the tree branch 14 to be cut on the through groove 91, the lower side of the tree branch will come into contact with the tilted end and the longest side of the triangular flip plate 941, and the triangular flip plate 941 will be pressed around its own axis by its partial gravity until the longest side of the triangular flip plate 941 is in a horizontal state in the through groove 91, and the triangular flip plate 941 that is not subjected to the pressure of the tree branch will still maintain its initial state. When the power unit 95 drives the moving slider 92 to move toward the cutting blade 5, the tree branch 14 to be cut away from the cutting blade 5 is near the end thereof. The triangular flip plate 941 with a tilted corner on the near side will push the tree branch 14 to be cut to move synchronously, thereby realizing the transportation of the tree branch. When the tree branch extends out of the working platform 2 to a required length, the power unit 95 can be used to reset the moving slider 92 with multiple triangular flip plates 941. During the resetting process, when the triangular flip plate 941 leaves the tree branch 14 to be cut, the end with less weight will be tilted up again in the through groove 91, and the end with more weight will fall back on the corresponding support rod 943, so as to re-drive the tree branch 14 to be cut next time.

[0039] Furthermore, if Figure 2 and Figure 3 As shown, the power unit 95 includes an electric cylinder 951 installed on the strip guide block 93 , and the output end of the electric cylinder 951 is fixedly connected to the moving slider 92 through a traction plate 952 .

[0040] In the above embodiments, the electric cylinder 951 is a product specially used for continuous motion, low to high load, and can be used repeatedly within its service life. It has extremely high positioning accuracy and controllability, and can achieve precise motion control under loads ranging from several kilograms to 50 tons. In this way, by controlling the telescopic length of the electric cylinder 951 in the present application, the moving distance of the slider 92 can be controlled each time. When the telescopic range of the electric cylinder 951 is large each time, the length of the wood strip cut by the cutting blade 5 will also be relatively large. When the telescopic range of the electric cylinder 951 is small each time, the length of the wood strip cut by the cutting blade 5 will also be relatively small. In this way, wood strips of various lengths can be cut as needed during use.

[0041] Furthermore, if Figure 1 and Figure 5 As shown, an inclined baffle 10 is respectively installed on both sides of the working platform 2 along the width direction of the through groove 91, and the cross-section of the two inclined baffles 10 is an inverted eight-shaped shape.

[0042] In the above embodiments, the two inclined baffles 10 of the present application are arranged in the above manner, and a groove that guides the tree branches 14 to be cut can be formed on the outside of the through groove 91 on the working platform 2. This not only facilitates farmers to quickly place the tree branches 14 to be cut on the through groove 91, but also prevents the tree branches 14 to be cut from leaving the through groove 91 when the automatic clamping unit 94 in the through groove 91 moves the tree branches 14 to be cut toward the cutting blade 5.

[0043] Furthermore, if Figure 1 and Figure 2 As shown, there is a gap between the inclined baffle 10 and the cutting blade 5, and a temporary pressing component 11 is provided between the inclined baffle 10 and the cutting blade 5;

[0044] The temporary pressing assembly 11 includes a door frame 111, in which a clamping plate 112 is slidably connected in the vertical direction. The upper end of the clamping plate 112 is fixedly connected to the lower end of the guide column 113. The upper end of the guide column 113 passes through the upper end plate of the door frame 111, and the guide column 113 is slidably connected to the upper end plate of the door frame 111 in the vertical direction. A spring 114 is provided between the upper end plate of the door frame 111 and the clamping plate 112, and the spring 114 is movably sleeved on the guide column 113.

[0045] In the above embodiment, when the cutting blade 5 cuts the tree branch, the end of the tree branch in contact with the cutting blade 5 will be subjected to a vertical downward force, and the other end of the tree branch will easily tilt upward if not restricted, affecting the cutting effect, so the farmer may need to hold the tree branch when cutting. In the present application, a clamping plate 112 that can move in the vertical direction is provided in the door frame between the cutting blade 5 and the inclined baffle 10. The spring 114 installed on the guide column 113 that guides the movement of the clamping plate 112 can make the distance between the clamping plate 112 and the working platform 2 smaller than the diameter of the tree to be cut in the natural state. In this way, when the tree branch 14 to be cut squeezes under the clamping plate 112, the spring 114 will be compressed by the clamping plate 112 to generate elastic force, which will act on the tree branch 14 to be cut through the clamping plate 112, thereby generating downward pressure on the tree branch 14 to be cut, saving the trouble of farmers pressing when cutting the tree branch, thereby improving the convenience of the present application when using.

[0046] Furthermore, if Figure 5 As shown, the lower side of the clamping plate 112 away from the cutting blade 5 is rounded.

[0047] In the above embodiment, the splint 112 of the present application is arranged in the above manner. When the tree branch 14 to be cut moves toward the cutting blade 5, the splint 112 can be lifted up from the rounded corner side. In this way, the tree branch 14 to be cut can automatically open the splint 112, making the device of the present application more convenient to use.

[0048] Further, as Figure 5 shown, on the working platform 2, a placing board 12 is provided on one side of one of the inclined baffles 10, and one end of the placing board 12 close to the inclined baffle 10 is lower than the other opposite end.

[0049] In the above embodiments, the placing board 12 provided on one side of the inclined baffle 10 of the present application can be used to temporarily store the tree branches to be cut. One end of the placing board 12 close to the inclined baffle 10 is lower than the other opposite end. In this way, after a farmer takes a tree branch 14 to be cut from the lower-height side of the inclined baffle 10, the remaining tree branches on the placing board 12 will automatically move downward along the placing board 12 to fill the gap after taking away the tree branch, so that it is convenient for the farmer to continuously take tree branches from the placing board 12.

[0050] Further, as Figure 1 and Figure 5 shown, outside the higher end of the placing board 12, an intercepting board 13 is provided, and the lower end of the intercepting board 13 is fixedly installed on the working platform 2.

[0051] In the above embodiments, the intercepting board 13 provided outside the higher end of the placing board 12 and the inclined baffle 10 at the lower end of the placing board 12 can jointly form a trough-shaped structure with the placing board 12, so as to facilitate storing more tree branches 14 to be cut.

[0052] The implementation principle of this embodiment is as follows: Before use, the farmer first selects tree branches with similar lengths and diameters meeting the requirements, and then places part of these tree branches on the placing board 12 of the present application. During use, the driving motor 8 is started. At this time, the cutting blade 5 will continuously perform cutting actions at one end of the working platform 2 under the drive of the driving motor 8. As Figure 2 shown, then the farmer can take a tree branch 14 to be cut from the placing board 12 adjacent to the inclined baffle 10 and place it on the through groove 91 between the two inclined baffles 10. At this time, the triangular turnover plates 941 in contact with the tree branch all rotate, so that their longest sides become horizontal in the through groove 91. At this time, the farmer can turn on the electric cylinder 951. After the electric cylinder 951 is started, its output end will first extend towards the cutting blade 5, and this process will drive the moving slider 92 to also move towards the cutting blade 5.

[0053] When the tilted end of the triangular flip plate 941 away from the outer side of one end of the cutting blade 5 comes into contact with the tree branch 14 to be cut, the triangular flip plate 941 will push the tree branch 14 to be cut to move toward the cutting plate. When the tree branch 14 to be cut comes into contact with the clamping plate 112, the clamping plate 112 will be opened, and the clamping plate 112 will press the spring 114 upward. The elastic force generated by the compression and deformation of the spring 114 will produce a downward squeezing force on the tree branch 14 to be cut. As the tree branch 14 to be cut continues to move, as shown in FIG. Figure 3 As shown, when the length of the cutting blade 5 extending out of the working platform 2 meets the required length, the cutting blade 5 just moves from top to bottom. In this process, the electric cylinder 951 drives the moving slider 92 to reset with the multiple triangular flip plates 941, as shown in FIG. Figure 4 As shown, when the cutting blade 5 falls, it will only cut tree branches, and the cut tree branches meet the length of wood strips required by farmers to grow fungi. When the cutting blade 5 is lifted upward, the electric cylinder 951 will drive the tree branch 14 to move a certain distance in the direction of the cutting blade 5 through the triangular flip plate 941 on the outer side of the end away from the cutting blade 5. After the extension distance of the tree branch 14 to be cut meets the requirements, the electric cylinder 951 will reset with the moving slider 92 and the multiple triangular flip plates 941 thereon, and the cutting blade 5 will fall again to complete the cutting of the tree branches and wood strips. In this way, when the wood strips on the through groove 91 are almost processed after multiple cycles, the farmer can place a new tree branch 14 to be cut on the through groove 91. Compared with the prior art, the equipment of the present application is obviously more labor-saving and efficient when cutting tree branches, and the cutting length of the tree branches can also be controlled by adjusting the extension amount of the electric cylinder 951, which is very practical to use.
