Description

Technical Field

[0001] The present application relates to the technical field of bamboo processing equipment, and in particular to a bamboo delimbing machine and bamboo equipment. Background Art

[0002] As the world's timber resources decrease, bamboo resources are increasingly valued by people for their short growth cycle. After bamboo is cut down by machinery, it needs to be delimbed on the spot, which has always been done by people manually. The traditional manual bamboo delimbing method is labor-intensive, inefficient and unsafe.

[0003] Since bamboo is generally long, with different diameters, and is grown in hilly and mountainous areas with inconvenient transportation, mechanized pruning is a problem. Although there are more and more machines for bamboo harvesting, there are still few machines for bamboo pruning, and a lot of manual assistance is still required. For example, the bamboo pruning machine disclosed in Chinese Patent 202010262584.5 can automatically prune bamboo, but it requires manual assisted loading, and considering the length of the bamboo itself, manual loading is very inconvenient.

[0004] Specifically, because bamboo branches are mostly above 10 meters, there is no branch for a long time near the root, and the existing bamboo debranching machine starts debranching from the root, resulting in low processing efficiency. In addition, considering the length of the bamboo, manual feeding is very inconvenient. Summary of the invention

[0005] The technical problem to be solved by the present application is to propose a bamboo delimbing machine and bamboo equipment in view of the above-mentioned deficiencies in the prior art.

[0006] A bamboo delimbing machine, comprising:

[0007] frame;

[0009] The delimbing assembly comprises at least three saw blade units; all the saw blade units are arranged in a circle around the circumference and are used to delimb bamboo placed therein; each saw blade unit comprises a saw blade and a second driving source for driving the saw blade to rotate;

[0010] The floating assembly comprises a floating frame installed on the frame and capable of floating up and down, and a pressure wheel installed on the floating frame; the pressure wheel is located above the track assembly, is used to press down the bamboo in the feeding structure, and can rotate freely along the bamboo feeding direction.

[0011] In a technical solution, the floating assembly further comprises: an elastic component installed between the frame and the floating frame; the elastic component is used to elastically press down the floating frame so that the pressure wheel presses the bamboo.

[0012] In one technical solution, the first saw blade unit is located at an upper position; the first saw blade unit is installed on the floating frame.

[0013] In a technical solution, the floating assembly further comprises a lifting element mounted on the frame; the lifting element can act on the floating frame to raise the height of the floating frame; the lifting element is separable from the floating frame.

[0014] In one technical solution, the floating frame includes: an upper crossbeam, a first mounting frame for mounting a pressure wheel, a second mounting frame for mounting a first saw blade unit, a first sliding rod connecting the upper crossbeam and the first mounting frame, and a second sliding rod connecting the upper crossbeam and the second mounting frame; the first sliding rod and the second sliding rod are slidably mounted on the frame and can slide up and down relative to the frame.

[0015] In one technical solution, the elastic component is at least one spring installed between the frame and the floating frame.

[0016] In one technical solution, the lifting element is an electric element, a pneumatic element or a hydraulic element.

[0020] The present application provides a bamboo delimbing machine, which performs automatic feeding through a V-shaped feeding structure formed by the first side wall of the first crawler and the second side wall on the second crawler, and performs delimbing through multiple saw blade units of a delimbing assembly. The technical solution of the present application has the following technical effects: First, feeding through the crawler assembly is more efficient and reduces manpower participation.

[0024] The following is the specific embodiment of the present application and in conjunction with the accompanying drawings, the technical scheme of the present application is further described, but the present application is not limited to these embodiments. In the following description, specific details such as specific configuration and assembly are provided only to help fully understand the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, for clarity and brevity, the description of known functions and structures has been omitted.

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other.

[0026] refer to Figures 1 to 3 The present application provides a bamboo delimbing machine, comprising: a frame 100, a crawler assembly, a delimbing assembly 200, and a floating assembly. The crawler assembly is used to drive the bamboo to move along the bamboo trunk to achieve automatic loading. The delimbing assembly 200 is used to remove branches and leaves on the bamboo trunk during the movement of the bamboo. In some technical solutions of the present application, the bamboo delimbing machine is installed on a crawler chassis, and can be freely moved with the help of the crawler chassis.

[0027] The track assembly includes a first track 10, a second track 20, and first driving sources 30 and 40 for driving the first track 10 and the second track 20; wherein the first track 10 and the second track 20 are located on opposite sides; at the inner position between the first track 10 and the second track 20, a first side wall 11 on the first track 10 and a second side wall 21 on the second track 20 extend in the front-to-rear direction and form a V-shaped feeding structure.

[0028] When the bamboo delimbing machine is working, the track assembly is used to drive the bamboo to move along the bamboo trunk to achieve automatic loading. The delimbing assembly 200 is used to remove branches and leaves on the bamboo trunk during the movement of the bamboo. Figures 1 to 3 The bamboo is placed in a V-shaped feeding structure and is supported by the first side wall 11 and the second side wall 21 on both sides. As the first driving source 30 and 40 drive the first crawler 10 and the second crawler 20 to operate respectively, the bamboo moves together. At this time, the saw blade of the debranching assembly rotates to remove the branches and leaves on the bamboo. During feeding, the first side wall 11 on the first crawler 10 and the second side wall 21 on the second crawler 20 are in surface contact with the bamboo over a certain length, thereby providing sufficient feeding friction to ensure smooth feeding and protect the bamboo surface from damage.

[0029] Further references Figure 1 and Figure 2 , the first driving source includes driving source 1 30 and driving source 2 40, driving source 1 30 is used to drive the first crawler 10 to operate, and driving source 2 40 is used to drive the second crawler 20 to operate. Driving source 1 30 and driving source 2 40 can be electric devices, pneumatic devices, hydraulic devices, and internal combustion engines. For example, electric motors, hydraulic motors, starter motors, and engines. It should be understood that the first driving source can directly drive the driving wheel of the crawler to rotate. In addition, other intermediate transmission components can be provided between the first driving source and the driving wheel of the crawler, and the first driving source can drive the driving wheel of the crawler through the intermediate transmission components, such as gears, chains, etc. The crawler device also needs to include some other necessary components. Exemplarily, the crawler device includes: driving wheels, supporting wheels, guide wheels, traction wheels and crawlers, tensioning devices, and buffer springs.

[0030] In some embodiments, the first crawler 10 and the second crawler 20 are both rubber crawlers. The rubber crawler is a soft material and can increase greater friction and is not easy to slip, thereby ensuring smooth feeding, not easy to damage bamboo, and not easy to slip.

[0031] refer to Figures 1 to 3, the debranching assembly 200 includes at least three saw blade units; all the saw blade units are arranged in a circle around the circumference, and are used to debranch the bamboo placed therein; wherein the first saw blade unit is located at the upper position; each saw blade unit includes a saw blade 212 and a second drive source 211, and the second drive source 211 is used to drive the saw blade to rotate. The saw blade 212 can specifically be a circular saw. Each saw blade debranching unit can be individually configured with a second drive source 211, or multiple saw blade debranching units can share a second drive source 211. The second drive source 211 can be an electric device, a pneumatic device, a hydraulic device, or an internal combustion engine. For example, an electric motor, a pneumatic motor, or an electric motor. Driven by the second drive source 211, the saw blade 212 rotates to remove the bamboo branches.

[0032] In some embodiments, the delimbing assembly 200 includes three saw blade units, specifically: a first saw blade unit 210a located at an upper position, and a second saw blade unit 210b and a third saw blade unit 210c located at two side positions at the lower side.

[0033] When the bamboo delimbing machine is working, the bamboo to be delimbed is placed in the middle of the plurality of saw blade units, and the saw blade 212 starts to rotate at a high speed under the drive of the second driving source 211, and the saw blade 212 of each saw blade unit removes the bamboo branches. When the crawler assembly drives the bamboo to move along the bamboo trunk direction for feeding, the saw blade 212 removes the bamboo branches.

[0034] The floating assembly includes a floating frame 51 and a pressure wheel 52. The floating frame 51 is installed on the frame and can float up and down, and the pressure wheel 52 is installed on the floating frame 51; the pressure wheel 52 is located above the track assembly, used to press down the bamboo in the feeding structure, and can rotate freely along the feeding direction of the bamboo. The pressure wheel can float up and down adaptively with the floating frame 51. When the diameter of the bamboo changes, it can automatically adapt to the diameter of the bamboo. Specifically, when the diameter of the bamboo increases, the bamboo pushes the pressure wheel 52 and the floating frame 51 upward, so that the pressure wheel 52 moves up and away from the track assembly; when the diameter of the bamboo becomes smaller, the pressure wheel 52 and the floating frame 51 move down, keep in contact with the surface of the bamboo, and press the bamboo. When the track assembly drives the bamboo forward, the pressure wheel 52 will rotate along the feeding direction of the bamboo. In some technical solutions, the pressure wheel 52 can be a rubber tire.

[0035] In some embodiments, the floating assembly further includes an elastic component 53, which is installed between the frame and the floating frame 51; the elastic component 53 is used to elastically press the floating frame 51 downward so that the pressure wheel 52 presses the bamboo. Further, the elastic component 53 is at least one spring installed between the frame and the floating frame 51. The elastic component 53 applies a downward elastic force to the floating frame 51, so that the pressure wheel 52 presses the bamboo. The floating frame 51 floats up and down under the elastic force constraint of the elastic component 53. When the diameter of the bamboo changes, the pressure wheel 52 elastically floats up and down, automatically adapting to the diameter of the bamboo.

[0036] Furthermore, the first saw blade unit is located at the upper position; the first saw blade unit is installed on the floating frame 51. Typically, the debranching assembly 200 includes three saw blade units, specifically: a first saw blade unit 210a located at the upper position, and a second saw blade unit 210b and a third saw blade unit 210c located at the lower two sides respectively. The first saw blade unit located at the top can float up and down with the entire floating assembly, and the debranching assembly 200 can better adapt to bamboos of different diameters.

[0037] When loading, the floating frame 51 can be lifted, the first saw blade unit and the pressure wheel 52 can be moved upward, the first saw blade unit can be separated from the other saw blade units below, and the pressure wheel 52 can also be moved away from the track assembly. At this time, the bamboo can be horizontally translated and placed into the V-shaped feeding structure and the debranching assembly 200. After the bamboo is placed, the floating frame 51 is lowered, the pressure wheel 52 is pressed on the bamboo, and the first saw blade unit returns to the normal processing height and is surrounded by the other saw blade units below. In this way, by lifting the floating assembly, a gap is opened on the side of the floating assembly and the debranching assembly 200, so as to realize the lateral loading of the bamboo. Here, the lateral loading method can directly place the starting position of the bamboo branches on the bamboo trunk onto the debranching assembly 200, so that the debranching assembly 200 can start the debranching process from the position where there are branches on the bamboo trunk, thereby skipping a long section of the bamboo trunk without branches starting from the root, thus greatly improving the debranching efficiency of the equipment.

[0038] In some embodiments, the floating assembly further includes a lifting element 54 mounted on the frame; the lifting element 54 can act on the floating frame 51 to raise the height of the floating frame 51; the lifting element 54 is separable from the floating frame 51. The lifting element 54 is not connected to the floating frame 51. When working, the floating frame 51 is first lifted to an appropriate height using the lifting element 54, and then moved horizontally to put the bamboo in. Then, the lifting element 54 lowers the floating frame 51, and the pressure wheel 52 is elastically pressed on the bamboo under the action of the elastic component 53. In some embodiments, the lifting element 54 is an electric element, a pneumatic element, or a hydraulic element. For example, an oil cylinder, an air cylinder, etc.

[0039] Further references Figure 1 The floating frame 51 includes an upper crossbeam 511, a first mounting frame 512, a second mounting frame 513, a first sliding rod 514, and a second sliding rod 515. The first mounting frame 512 is used to mount the clamping wheel 52, the second mounting frame 513 is used to mount the first saw blade unit, the first sliding rod 514 connects the upper crossbeam 511 and the first mounting frame 512, the second sliding rod 515 connects the upper crossbeam 511 and the second mounting frame 513, and the first sliding rod 514 and the second sliding rod 515 are slidably mounted on the frame and can slide up and down relative to the frame.

[0040] In the technical solution of the present application, the first side wall of the first crawler and the second side wall of the second crawler form a V-shaped feeding structure for automatic feeding, and delimbing is performed through multiple saw blade units of the delimbing assembly. In this way, feeding through the crawler assembly is more efficient and reduces manpower participation. The crawler-type V-shaped feeding structure can provide greater friction to the surface of the bamboo, ensure smooth feeding, and protect the surface of the bamboo from damage. The clamping wheel can float up and down. When the diameter of the bamboo changes, it can automatically adapt to the diameter of the bamboo.

[0041] In addition, in some technical solutions, a transverse loading method can be adopted, and the starting position of the bamboo branches on the bamboo trunk can be directly placed on the debranching component 200, so that the debranching component 200 can start the debranching process from the position where there are branches on the bamboo trunk, thereby skipping a long section of the bamboo trunk without branches starting from the root, thereby greatly improving the debranching efficiency of the equipment.

[0042] refer to Figure 3 The embodiment of the present application further provides a bamboo equipment, including the bamboo delimbing machine provided in the above part and a crawler chassis 300; the bamboo delimbing machine is installed on the crawler chassis 300. The crawler walking chassis can adapt to complex mountainous and hilly landforms and rainy working conditions.

[0043] When the bamboo delimbing machine is working, the crawler chassis 300 is parked on the side of the hillside, the power system is working, and the workers can put the bamboo on the delimbing assembly and the crawler assembly. The lifting element 54 is started to lift the floating frame 51 to an appropriate height, and then the bamboo is placed in the horizontal position. Under the action of gravity and the elastic component 53, the clamping wheel 52 clamps the bamboo. Then, the bamboo moves toward one end of the bamboo root under the friction of the rubber crawler, and the three circular saws arranged around the whole circle remove the bamboo branches and leaves passing by. The bamboo tip is deflected to one of the circular saws through flexible deflection and is delimbed.
