Description

Technical Field

[0001] The utility model belongs to the technical field of firewood splitters, and in particular relates to an auxiliary fixing seat device for firewood splitters. Background Art

[0002] A wood splitter is a mechanical device used for processing wood and cutting firewood. It belongs to the category of woodworking tools and has a wide range of applications. It mainly uses an electric hydraulic mechanism to cooperate with a knife head to cut the wood placed on the track.

[0003] In the Chinese patent with publication number CN208179842U, an auxiliary fixing seat device for an agricultural wood splitter is mentioned, which can change the distance between the clamping plates according to the general size of the wood. The clamping plates on both sides can effectively limit the wood, avoid rolling, and facilitate the splitting of the wood;

[0004] During the use of the above-mentioned equipment, although the clamping plates on both sides can position and clamp the wood, when chopping wood, the operation of the hydraulic cylinder will push the wood, and the clamping of the clamping plates on the wood will increase a certain friction, and thus a larger output of the hydraulic cylinder is required to push the wood. In addition, after one use, the two clamping plates need to be manually separated again to position and clamp the next piece of wood, thus limiting work efficiency. Utility Model Content

[0005] The utility model aims to provide an auxiliary fixing seat device for a wood splitter to solve the problem of low working efficiency in the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An auxiliary fixing seat device for a wood splitter comprises a hydraulic cylinder, a receiving assembly and an auxiliary assembly, wherein a guide rail 1 is fixedly connected to the lower part of the hydraulic cylinder, an auxiliary assembly is installed at one end of the guide rail 1, a cutter head is installed at the output end of the hydraulic cylinder, and a receiving assembly is arranged below the cutter head;

[0008] The receiving assembly comprises a receiving block, a pushing block and a sliding block, wherein the pushing block is used to actively press down the linkage block;

[0009] The auxiliary components include a second guide rail, a linkage block, a pushing block, a connection block and a second sliding block. The second guide rail is used to guide the receiving block and the second sliding block. The linkage block is used to receive the wood. The connection block cooperates with the pushing block to clamp and position the wood.

[0010] Preferably, evenly distributed connecting grooves are provided inside the guide rail 2, limiting grooves are provided on both sides of the guide rail 2, the linkage block is inserted into the connecting grooves, and the bottom of the push block is slidably connected to the limiting grooves.

[0011] Preferably, two left - and - right symmetric connecting rods are rotatably connected to the lower end of the linkage block. The lower end of the connecting rod is rotatably connected to one side of the pushing block. The connecting block is rotatably connected to the side of the second sliding block away from the second guide rail. A resilient plate is fixedly connected to the side of the connecting block away from the second sliding block, and the resilient plate is used to contact the wood.

[0012] Preferably, the side of the pushing block away from the connecting rod is attached to the side of the connecting block.

[0013] Preferably, a pressing block is fixedly connected inside the receiving block, and the pressing block is located above the linkage block.

[0014] Preferably, guide grooves one and two are provided on both sides of the second guide rail and the first guide rail, and the first guide rail is located above the guide groove one.

[0015] Preferably, two symmetric sliding blocks one are fixedly connected to the bottom of the receiving block. The sliding block one is slidably connected inside the guide groove one, and one side of the sliding block two is slidably connected inside the guide groove two.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] First, through the hydraulic cylinder provided in the present utility model, the receiving assembly and the auxiliary assembly cooperate with each other. After the wood is placed above the linkage block, the gravity of the wood itself causes the connecting block to drive the resilient plate to rotate, thereby initially positioning and clamping the wood. At the same time, after the hydraulic cylinder operates, it will press down on the linkage block again through the pressing block, thereby completing the secondary clamping. After the positioning and clamping are completed, due to the frictional force during clamping and the continuous operation of the hydraulic cylinder, the second sliding block drives the connecting block to move, thereby reducing the frictional force during clamping and then reducing the energy consumption of the hydraulic cylinder.

[0018] Second, through the hydraulic cylinder provided in the present utility model, the receiving assembly and the auxiliary assembly cooperate with each other. After the connecting block drives the resilient plate to rotate to clamp and position the wood, and after the second sliding block slides along with the receiving block, the wood will be cut by the cutting head fixed above the receiving block and scattered on the bottom surface. At this time, the gravity above the linkage block is lost. After the hydraulic cylinder contracts, the pressing block behind the bottom of the receiving block no longer presses the linkage block. At this time, the resilient plate will return to the horizontal state under the action of gravity, thereby eliminating the need for manual opening and closing of the auxiliary clamping resilient plate, thus improving work efficiency.

[0031] In this embodiment, the connecting rod 55 is rotatably connected through an insertion shaft, and there is a bearing at the insertion shaft, so that the connecting rod 55 can be transmitted, and the top end of the connecting rod 55 is initially close to the middle; the pushing block 56 is composed of a left vertical plate, a middle connecting plate and a slider, wherein the slider is slidably connected inside the limiting groove 52, and the middle connecting plate is used to connect one end of the connecting rod 55, and the left vertical plate is used to push the connecting block 57; the tough plate 58 is a metal plate with a certain toughness, and initially has a certain degree of curvature, so after the connecting block 57 rotates, the tough plate 58 and the upper end surface of the connecting block 57 can initially clamp the wood.

[0032] In a further embodiment, a side of the pushing block 56 away from the connecting rod 55 is attached to a side of the connecting block 57 .

[0033] In this embodiment, the connecting block 57 is composed of a horizontal plate and a vertical plate, wherein the horizontal plate is used to connect the sliding block 2 59 and the tough plate 58, and the vertical plate is used to fit the left vertical plate of the pushing block 56, and the left vertical plate of the pushing block 56 has a certain chamfered surface, so when the pushing block 56 moves as a whole, it will push the connecting block 57, so that the connecting block 57 passively rotates, and in addition, there are balls at the place where the vertical plate of the connecting block 57 fits the pushing block 56 to reduce friction; the part of the sliding block 2 59 that is slidably connected in the guide groove 2 33 has balls to reduce the friction between the two, so that the sliding block 2 59 can better slide with the connecting block 57 and the tough plate 58 as the receiving block 41 slides.

[0034] In a further embodiment, a pushing block 42 is fixedly connected inside the receiving block 41 , and the pushing block 42 is located above the linkage block 54 .

[0035] In this embodiment, one end of the push block 42 has a cut surface so that the linkage block 54 can be pressed down during the movement of the guide rail 51, and the thickness of the limiting groove 52 can allow the linkage block 54 to move downward to the maximum extent when pressed down, at which time the connecting block 57 will rotate 90°.

[0036] In a further embodiment, guide groove 1 32 and guide groove 2 33 are provided on both sides of guide rail 2 51 and guide rail 1 31 , and guide rail 1 31 is located above guide groove 1 32 .

[0037] In this embodiment, the guide rail 1 31 is completely identical to the guide rail 2 51 except that the connecting groove 53 and the limiting groove 52 are not provided.

[0038] In a further embodiment, the bottom of the receiving block 41 is fixedly connected with two symmetrical sliding blocks 43, the sliding block 43 is slidably connected inside the guide groove 32, and one side of the sliding block 59 is slidably connected inside the guide groove 33.

[0039] In this embodiment, a baffle is installed at one end of the guide rail 2 51 away from the guide rail 1 31 to support the wood, so that the hydraulic cylinder 1 can cut the wood through the cutter head 2 when it is in operation.

[0040] The working principle of the utility model is as follows:

[0041] When the hydraulic cylinder 1 is in operation, the wood placed on the linkage block 54 will be pushed by the cutter head 2, and the baffle placed at the end of the track can be used to cut the wood;

[0042] When the hydraulic cylinder 1 is in operation and pushes the cutter head 2, the receiving block 41 also slides accordingly, so that the pushing block 42 will press one end of the linkage block 54 downward, thereby causing the linkage block 54 to move downward, and then the pushing blocks 56 on both sides of the guide rail 2 51 are driven away from each other by the connecting rod 55, so that the pushing block 56 will push the bottom end of the connecting block 57 until the connecting block 57 rotates 90°, at which time the toughness plate 58 will fit closely to the wood to complete the positioning and clamping of the wood;

[0043] When the wood is placed on the linkage block 54, the linkage block 54 will move downward due to its own gravity, so that the connection block 57 can rotate a small angle with the tough plate 58. However, since the tough plate 58 is curved, the wood will be initially clamped.

[0044] As the toughness plate 58 tightly clamps the wood, the sliding block 2 59 will also move due to friction when the hydraulic cylinder 1 is operating to push the wood through the cutter head 2, thereby avoiding the hydraulic cylinder 1 requiring more energy to push due to friction when pushing the wood;

[0045] After the cutting of the wood is completed, since there is no wood above the linkage block 54, the resilient plate 58 will rotate the connecting block 57 in the reverse direction back to the initial position under the action of its own gravity. In addition, after the cutting of the first piece of wood is completed, it is necessary to manually push the slider two 59 back to its original position so as to be adaptable to woods of different lengths.

[0046] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
