[0001] The utility model belongs to the technical field of wood chippers. Background Art
[0002] Wood chippers are commonly used equipment in the wood processing industry and come in a variety of forms. A simple wood chipper feeds logs into a feed roller, which is clamped by a pair of feed rollers and sent to a knife roller for cutting into wood chips. The feeding method used is to use a belt or chain plate to convey the material in a gap-type manner. Due to the gap between the belt or chain plate and the feed roller, the material is easily stuck, causing the belt and chain plate to be easily damaged, resulting in high maintenance costs, and often causing production stagnation, affecting normal production. In addition, due to the load-bearing and design size limitations of the belt and chain plate, too much material cannot be fed, resulting in low production efficiency. Summary of the invention
[0003] The utility model aims to solve the problem of material jamming in the existing wood chippers and to provide a wood chipper which has high production efficiency and will not jam the material and adopts a material frame to reciprocate and feed the material.
[0004] The technical solution adopted by the utility model is as follows.
[0005] A wood chipper adopting a material frame reciprocating feeding comprises a frame, a knife roller frame arranged in the frame, a cutting knife roller installed in the knife roller frame and rotating in a clockwise direction, a cylindrical screen arranged at the periphery of the cutting knife roller and having a feeding slot on the upper part, a discharging belt arranged below the knife roller and the screen, a reciprocating loading frame arranged on the upper part of the frame and above the cutting knife roller, and a top plate arranged on the top surface of the loading frame and having a feeding slot in the middle; the feeding slot on the upper part of the screen is a skewed slot with a higher left side and a lower right side, and the slot is The left and right sides are respectively connected with a high extension plate and a low extension plate that extend horizontally to the outside of the knife roller frame; the loading frame is a rectangular frame basket with an extended table top on the top and no frame bottom, the bottom end of the left frame plate of the frame basket is located on the high extension plate, the bottom end of the right frame plate is located on the low extension plate, and the front and rear frame plates are respectively fixed on the left frame plate and the right frame plate; horizontal push-pull cylinders are arranged on the upper part of the frame at both sides of the loading frame, and the front ends of the push rods of the two push-pull cylinders are respectively connected to the front frame plate and the rear frame plate of the loading frame.
[0006] Furthermore, a feed box with one side open is arranged on the top of the loading frame, a dust collecting hood is arranged on the top of the feed box, and the dust collecting hood is externally connected to a dust removal system.
[0007] Furthermore, rollers that can roll along the frame crossbeams are arranged on the periphery of the frame basket of the charging frame.
[0008] By adopting the utility model, the wood can be loaded into the loading frame by a loader. It is only necessary to increase the width and volume of the loading frame to realize more loading. After the wood is loaded into the loading frame, the loading frame moves back and forth to push the wood into the high-speed rotating knife roller to be cut into pieces, and then falls onto the discharging belt through the screen. After the wood in contact with the guide roller at the bottom is cut, the wood at the top automatically falls. The larger wood pieces that fail to pass through the screen will be brought out by the knife roller and pushed to be cut again until they fall into the belt conveyor with the qualified size, and there will be no jamming. When the motor exceeds the specified load, the pushing cylinder will automatically slow down or stop, so as to protect the motor. The utility model no longer uses belts or chain plates for feeding, simplifies the equipment structure, makes the equipment operation more reliable and consumes less energy, and does not cause jamming, reduces maintenance costs, and improves production efficiency.

[0012] The content of the utility model is further described below in conjunction with the accompanying drawings of the specification.
[0013] like Figure 1 , Figure 2 , Figure 3As shown, a wood chipper adopting a material frame reciprocating feeding comprises a frame 1, a knife roller frame 2 arranged in the frame, a cutting knife roller 3 installed in the knife roller frame and rotating in a clockwise direction, a cylindrical screen 4 arranged at the periphery of the cutting knife roller and having a feeding slot on the upper part, a discharging belt 5 arranged below the knife roller and the screen, a reciprocating loading frame 6 arranged at the upper part of the frame and located above the cutting knife roller, and a top plate 7 arranged on the top surface of the loading frame and having a feeding slot in the middle. The feeding slot on the upper part of the screen 4 is an oblique slot with the left side higher and the right side lower, and the left and right sides of the slot are respectively connected with a high extension plate 8 and a low extension plate 9 extending horizontally outward to the outside of the knife roller frame. The loading frame 6 is a rectangular frame with an extension table 6a at the top and no frame bottom. The bottom of the left frame plate 6b of the frame is located on the high-position extension plate 8, and the bottom of the right frame plate 6c is located on the low-position extension plate 9. The front and rear frame plates are respectively fixed on the left frame plate and the right frame plate. The high-position extension plate 8 and the low-position extension plate 9 are equivalent to the frame bottom of the frame, but the frame bottom does not move. The frame can be reciprocated steadily between the top plate 7 and the high-position extension plate 8 and the low-position extension plate 9, and will not move up and down, and the operation is stable and reliable. In order to make the frame movement smoother, a roller 6d that can roll along the frame crossbeam can be set on the periphery of the frame. On the upper part of the frame, a horizontal push-pull oil cylinder 10 is arranged on both sides of the loading frame, and the push rod front ends of the two push-pull oil cylinders are respectively connected to the front frame plate and the rear frame plate of the loading frame.
[0014] The motor 13 for driving the cutter roller is arranged outside the cutter roller frame, and the output shaft of the motor drives the cutter roller main shaft after passing through the pulley device. The transmission device and the cutter roller are prior art equipment and will not be described in detail here.
[0015] In order to prevent excessive scattering of materials and protect the environment, a feed box 11 with one side open is arranged on the top of the loading frame, and a dust collecting hood 12 is arranged on the top of the feed box. The dust collecting hood is connected to an external dust removal system to solve the problem of dust treatment generated by chipping.
[0016] The working process of the utility model is as follows:
[0017] The loader is used to feed the material to be sliced (usually cut logs, large wood blocks, edge skin, etc.) from the open port on one side of the feed box 10. The material is put into the loading frame 6 through the feed port on the top plate 7. The push-pull cylinder 9 is activated to push the loading frame to reciprocate. The loading frame pushes the material close to the high-speed rotating knife roller and is cut into slices. The material passes through the screen and falls onto the discharge belt to be sent out. Figure 1 As shown, the knife roller rotates clockwise, and the loading frame reciprocates under the drive of the push-pull cylinder 6, pushing the falling materials toward the knife roller. The larger wood chips that fail to pass through the screen will be brought out by the knife roller and pushed for cutting again until the wood chips meet the size and fall into the belt conveyor.
[0018] The left frame plate 5b and the right frame plate 5c of the frame basket act as push plates. The left frame plate 5b can push the material from the high position on the left side of the feed slot of the screen 4 to the knife roller, and the right frame plate 5c can push the material from the low position on the right side of the feed slot of the screen 4 to the knife roller, so as to realize left-right alternating pushing of materials. In addition, the feed slot of the screen is set as an oblique slot with the left side higher and the right side lower, which can ensure that the material is cut by the knife roller rotating at high speed in the clockwise direction and brought into the screen, preventing the material from floating above the knife roller and being pushed back and forth to reduce the cutting efficiency. Figure 1 As shown, the feed slot width of the screen is usually about 1 / 4 of the circumference.
[0019] By adopting the utility model, the loader can continuously load materials into the loading frame, and can continuously load materials in large quantities, with high production efficiency. The dust generated by the chipping enters the dust removal system connected to the air outlet 11a on the dust collecting cover 11 for treatment. The dust removal system can adopt a commonly used cyclone dust collector or other conventional dust removal equipment to effectively treat the dust generated by the chipping and purify the production environment.
[0020] Compared with chippers that use belts or chains to feed materials, the utility model also embodies more excellent applicability and can process various types of wood, such as round logs of different thicknesses, edge barks, and wood blocks, especially various waste woods.
[0021] The up, down, left, right, front, back and clockwise directions expressing the relative positions described in the present invention are expressions based on the positional relationships shown in the drawings of the specification, and are not limitations on the structural positions of the chipper. The so-called left and right, front and back positional relationships and the rotation direction of the cutting roller can be adjusted and changed according to the actual installation conditions of the equipment, and such adjustments still fall within the protection scope of the present invention.
