Description

Technical Field

[0001] This invention relates to the field of wood splitting machine technology, and in particular to a wood splitting machine feeding mechanism and its feeding method. Background Technology

[0002] A log splitter is an agricultural and forestry device used to split wood. It transmits the motion and energy of a power source to the working part through a transmission mechanism or medium, and the working part splits the wood by pressing it. Generally, log splitters require the operator to place the wood in a designated work area in advance. When handling heavy wood or operating for a long time, this greatly increases the operator's labor intensity. At the same time, frequent loading and unloading operations also reduce labor efficiency and equipment energy efficiency.

[0003] Patent CN205685467U discloses a hydraulic wood splitter with a feeding device. This feeding device uses an additional hydraulic cylinder to push the feeding plate, raising the wood to a certain height and reducing labor intensity. However, it requires an additional hydraulic cylinder, which complicates the hydraulic system of the wood splitter, increases costs, and also increases the energy consumption of the hydraulic system. Furthermore, this feeding mechanism cannot be used on wood splitters without a hydraulic system. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a feeding mechanism and method for a wood splitter.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A feeding mechanism for a wood splitter includes a body with a main beam. A hydraulic cylinder is mounted on the upper rear end of the main beam, and a piston rod is installed inside the hydraulic cylinder. The piston rod is connected to a drive rod. A slider is slidably mounted on the upper rear end surface of the main beam, and a slide rod is mounted on the slider. The slide rod is inserted into the drive rod, and the end of the drive rod abuts against the slider. A hydraulic oil tank is also located on the lower side of the main beam on the body, and a base is mounted on the hydraulic oil tank. The base is connected to a feeding platform via a rotating shaft. A stop assembly for supporting the feeding platform is located at the front end of the main beam, and a cable connects the slider and the feeding platform. The center of gravity of the feeding platform is located in front of the rotating shaft. The base can be mounted on the hydraulic oil tank by bolts and nuts or by welding. The drive rod is tubular and hollow inside, and is fitted onto the slide rod. For a rack and pinion wood splitter, the drive rod can be mounted on the rack for splitting wood.

[0007] Preferably, the stop assembly includes a stop block, a bracket, a spring, and a handle. The stop block and the bracket are hinged together by a rotating shaft. An L-shaped bending plate is provided on the main beam, and the bracket is fixed to the L-shaped bending plate. One end of the handle passes through the main beam, and the other end of the handle passes through the L-shaped bending plate and the bracket, connecting to the stop block. The spring passes through the handle inside the bracket. A support block is provided on the top of the stop block, which contacts the loading platform. The inclined surface of the stop block also contacts the loading platform. Pulling the handle causes the stop block to rotate, and the stop block no longer presses against the loading platform. The loading platform then begins to rotate downwards under its own weight. The L-shaped bending plate is welded to the main beam. When the stop block supports the loading platform, the bottom of the stop block abuts against the bottom of the L-shaped bending plate, limiting the rotation of the stop block.

[0008] Preferably, an axe is connected to the end of the piston rod, and a connector is connected to the end of the drive rod away from the slider. The connector is connected to the axe and the piston rod by bolts and nuts. The connector has a through hole, through which the drive rod is connected to the piston rod by bolts and nuts. The drive rod can be mounted on the piston rod or on other components driven by the piston rod.

[0009] Preferably, a sliding plate is provided on the upper side of the main beam, a first bending plate is provided at one end of the slider, and a second bending plate is connected to the other end of the slider. The first bending plate and the second bending plate are in contact with the sliding plate respectively.

[0010] Preferably, the slider and the second bending plate are provided with a first connecting hole, and a side plate is connected to the rear side of the loading platform. The side plate is provided with a second connecting hole, and the cable is connected through the first connecting hole and the second connecting hole. The cable can be a soft rope of different materials, a chain, or a rigid rod, etc.

[0011] Preferably, the slider has a first end face and a second end face on both sides, and a U-shaped groove is provided on both the first end face and the second end face. The slide rod is disposed in the U-shaped groove, and the end of the drive rod near the slider abuts against the second end face. The slide rod is welded in the U-shaped groove.

[0012] Preferably, a baffle is provided on one side of the base located on the rotating shaft, and a support leg is connected to the bottom of the loading platform. The support leg is connected to the rotating shaft, and the baffle contacts the support leg. The baffle limits the movement of the support leg, thus limiting the loading platform.

[0013] Preferably, the hydraulic oil tank is located on the side of the base, and the unit is mounted thereon. The hydraulic cylinder is connected to a control lever, which is connected to the hydraulic oil tank and the unit via pipelines. The unit includes an engine assembly and a hydraulic pump that provides power to the hydraulic cylinder.

[0014] Preferably, a support base is connected between the main beam and the hydraulic oil tank, and support wheels are connected to both sides of the hydraulic oil tank.

[0015] A method for feeding a log splitter includes a log splitter feeding mechanism and further includes the following steps:

[0016] Step 1, Loading materials:

[0017] A: Pull the handle and keep the stop block rotating from the position that is holding the loading platform to the position that does not obstruct it. At this time, the stop block no longer blocks the loading platform, and the loading platform has the possibility of rotating downwards.

[0018] B: Manually push the control lever of the wood splitter forward. The piston rod moves forward under hydraulic drive, and the drive rod connected to the piston rod moves forward together. The drive rod no longer pushes against the slider. Since the center of gravity of the loading platform is on the other side of the rotation center, and the stop that prevents the loading platform from rotating in one direction is in an unobstructed position, the loading platform begins to rotate downward under its own weight. The slider is pulled forward together by the cable connected between the slider and the loading platform.

[0019] C: Place the wood on top;

[0020] D: Push the control lever of the wood splitter backward. The piston rod moves backward under hydraulic drive, and the drive rod connected to the piston rod moves backward along with it. The drive rod pushes the slider backward, and the slider pulls the loading platform upward through the cable. The loading platform pushes the inclined surface of the stop block, causing the stop block to rotate. The loading platform continues to rise, and after passing the support block on the stop block, it no longer contacts the inclined surface of the stop block. The stop block pops out under the push of its internal spring, and the piston rod moves to the designated position. At this time, the loading platform is slightly higher than the support block, and the loading is completed.

[0021] Step two, splitting wood:

[0022] E: Place the wood on the loading platform in the splitting area in front of the axe, push the control lever of the wood splitter forward, the piston rod moves forward under hydraulic drive, driving the axe to split the wood, and the drive rod moves forward together. The drive rod no longer pushes against the slider. Under the gravity of the loading platform and the wood on it, the loading platform has a tendency to rotate downward. Since the stop has been popped out, the loading platform rotates a small distance downward and is stopped by the stop. Without pulling the handle, no matter how the piston rod moves, the loading platform remains stationary.

[0023] This invention, by employing the above technical solutions, has significant technical effects: The loading platform is driven to rotate downwards by its own gravity; the return motion of the piston rod of the wood splitter drives the loading platform to rotate upwards; the inclined surface of the stop and the spring automatically restrict the loading platform to rotate only upwards, and support it when it rotates downwards; the stop is controlled by a handle to achieve downward rotation of the loading platform; the movement of the piston rod is transmitted to the slider by the drive rod; the movement of the slider is transmitted to the loading platform by the cable; the drive rod and slider are not fixedly connected, ensuring they can only push each other, not pull each other; the loading platform remains in the fully loaded state during normal wood splitting; the main beam of the wood splitter serves as a guide and limiter for the slider; and the baffle on the base restricts the rotation range of the loading platform.

[0024] The feeding mechanism provided by this invention uses the motion and energy of the axe's return stroke to drive the feeding platform. It does not require additional hydraulic mechanisms and makes full use of the energy of the axe's return stroke, which does not perform any work, thereby improving energy utilization, reducing the operator's labor intensity, and increasing labor efficiency.

Detailed Implementation

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] A feeding mechanism for a log splitter, such as Figure 1-8 As shown, the machine includes a body 1, a main beam 2 on the body 1, a hydraulic cylinder 4 mounted on the upper rear end of the main beam 2, a piston rod 401 inside the hydraulic cylinder 4, and a drive rod 8 connected to the piston rod 401. A slider 9 is slidably mounted on the upper rear end of the main beam 2, and a slide rod 10 is mounted on the slider 9. The slide rod 10 is inserted into the drive rod 8, and the end of the drive rod 8 abuts against the slider 9. A hydraulic oil tank 3 is also located on the body 1 below the main beam 2, and a base 5 is mounted on the hydraulic oil tank 3. The base 5 is connected to a loading platform 7 via a rotating shaft 6. A stop assembly 11 for supporting the loading platform 7 is located at the front end of the main beam 2. A cable 12 connects the slider 9 and the loading platform 7. The center of gravity of the loading platform 7 is located in front of the rotating shaft 6. The base 5 is mounted on the hydraulic oil tank 3 by bolts and nuts. The drive rod 8 is tubular and hollow inside, and is fitted onto the slide rod 10.

[0037] The stop block assembly 11 includes a stop block 1101, a bracket 1102, a spring 1103, and a handle 1104. The stop block 1101 and the bracket 1102 are hinged by a rotating shaft. An L-shaped bending plate 22 is provided on the main beam 2. The bracket 1102 is fixed on the L-shaped bending plate 22. One end of the handle 1104 passes through the main beam 2, and the other end of the handle 1104 passes through the L-shaped bending plate 22. The bracket 1102 is connected to the stop block 1101. The spring 1103 passes through the handle 1104 inside the bracket 1102. A support block 13 is provided on the top of the stop block 1101. The support block 13 contacts the loading platform 7, and the inclined surface of the stop block 1101 contacts the loading platform 7. Pulling handle 1104 causes stop 1101 to rotate, and stop 1101 no longer blocks the loading platform 7. The loading platform 7 then begins to rotate downwards under its own weight. The L-shaped bent plate 22 is welded to the main beam 2. When stop 1101 supports the loading platform 7, the bottom of stop 1101 abuts against the bottom of L-shaped bent plate 22, limiting the rotation of stop 1101.

[0038] An axe 14 is connected to the end of the piston rod 401, and a connector 801 is connected to the end of the drive rod 8 away from the slider 9. The connector 801 is connected to the axe 14 and the piston rod 401 by bolts and nuts. The connector 801 has a through hole, and the drive rod 8 is connected to the piston rod 401 through the through hole and bolts and nuts. The drive rod 8 can be mounted on the piston rod 401 or on other components driven by the piston rod 401.

[0039] The upper side of the main beam 2 is provided with a sliding plate 201, one end of the slider 9 is provided with a first bending plate 901, and the other end of the slider 9 is connected to a second bending plate 902. The first bending plate 901 and the second bending plate 902 are in contact with the sliding plate 201 respectively.

[0040] The slider 9 and the second bending plate 902 are provided with a first connecting hole 15. The rear side of the loading platform 7 is connected to a side plate 16, which is provided with a second connecting hole 1601. The cable 12 is connected through the first connecting hole 15 and the second connecting hole 1601. The cable 12 is a soft rope.

[0041] The slider 9 has a first end face 903 and a second end face 904 on both sides. Both the first end face 903 and the second end face 904 have U-shaped grooves 17. The slide rod 10 is located in the U-shaped groove 17. The end of the drive rod 8 near the slider 9 abuts against the second end face 904. The slide rod 10 is welded into the U-shaped groove 17.

[0042] A baffle 501 is provided on one side of the base 5, located on the rotating shaft 6. A support leg 701 is connected to the bottom of the loading platform 7. The support leg 701 is connected to the rotating shaft 6, and the baffle 501 is in contact with the support leg 701. The baffle 501 limits the support leg 701, that is, limits the loading platform 7.

[0043] A hydraulic oil tank 3 is located on the side of the base 5, and a unit 18 is provided. A control lever 19 is connected to the hydraulic cylinder 4. The control lever 19 is connected to the hydraulic oil tank 3 and the unit 18 through pipelines. The unit 18 includes an engine assembly and a hydraulic pump that provides power to the hydraulic cylinder 4.

[0044] A support seat 20 is connected between the main beam 2 and the hydraulic oil tank 3, and support wheels 21 are connected to both sides of the hydraulic oil tank 3.

[0045] Working principle: The loading platform 7 is driven to rotate downwards by its own gravity; the piston rod 401 of the wood splitter drives the loading platform 7 to rotate upwards by its return motion; the inclined surface of the stop block 1101 and the spring 1103 automatically restrict the loading platform 7 to rotate only upwards, and support the loading platform 7 when it rotates downwards; the stop block 1101 is controlled by the handle 1104 to realize the downward rotation of the loading platform 7; the drive rod 8 transmits the motion of the piston rod 401 to the slider 9; the cable 12 transmits the motion of the slider 9 to the loading platform 7; since there is no fixed connection between the drive rod 8 and the slider 9, the drive rod 8 and the slider 9 can only push each other and cannot pull each other; the loading platform 7 is kept in the fully loaded state during normal wood splitting; the main beam 2 of the wood splitter serves as a guide and limiter for the slider 9; the baffle 501 on the base 5 limits the rotation range of the loading platform 7.

[0046] The feeding mechanism provided by this invention uses the motion and energy of the axe's return stroke to drive the feeding platform. It does not require additional hydraulic mechanisms and makes full use of the energy of the axe's return stroke, which does not perform any work, thereby improving energy utilization, reducing the operator's labor intensity, and increasing labor efficiency.

[0047] Example 2

[0048] A method for feeding a log splitter includes a log splitter feeding mechanism and further includes the following steps:

[0049] Step 1, Loading materials:

[0050] A: Pull the handle 1104 and keep the stop block 1101 rotating from the position that is holding the loading platform 7 to the position that is not blocking it. At this time, the stop block 1101 no longer blocks the loading platform 7, and the loading platform 7 has the possibility of rotating downward.

[0051] B: Manually push the control lever 19 of the wood splitter forward, and the piston rod 401 moves forward under hydraulic drive. The drive rod 8 connected to the piston rod 401 moves forward together. The drive rod 8 no longer pushes against the slider 9. Since the center of gravity of the loading platform 7 is on the other side of the rotation center, and the stop block 1101 that unilaterally prevents the loading platform 7 from rotating is in an unobstructed position, the loading platform 7 begins to rotate downward under its own gravity. The slider 9 is pulled forward together by the cable 12 connected between the slider 9 and the loading platform 7.

[0052] C: Place the wood on top;

[0053] D: Push the control lever 19 of the wood splitter backward, and the piston rod 401 moves backward under hydraulic drive. The drive rod 8 connected to the piston rod 401 moves backward along with it. The drive rod 8 pushes the slider 9 to move backward together. The slider 9 pulls the loading platform 7 upward through the cable 12. The loading platform 7 pushes the inclined surface of the stop block 1101, causing the stop block 1101 to rotate. The loading platform 7 continues to rise, and after passing the support block 13 on the stop block 1101, it no longer contacts the inclined surface of the stop block 1101. The stop block 1101 pops out under the push of its internal spring 1103. The piston rod 401 moves to the designated position. At this time, the loading platform 7 is slightly higher than the support block 13, and the loading is completed.

[0054] Step two, splitting wood:

[0055] E: Place the wood on the loading platform 7 in the splitting area in front of the axe 14, push the splitter control lever 19 forward, the piston rod 401 moves forward under hydraulic drive, driving the axe 14 to split the wood, and the drive rod 8 moves forward together. The drive rod 8 no longer pushes against the slider 9. Under the gravity of the loading platform 7 and the wood on it, the loading platform 7 has a tendency to rotate downward. Since the stop block 1101 has been popped out, the loading platform 7 rotates down a small distance and is blocked by the stop block 1101. Without pulling the handle 1104, no matter how the piston rod 401 moves, the loading platform 7 remains stationary.

[0056] Example 3

[0057] The difference between Example 3 and Example 1 is that the base 5 is installed on the hydraulic oil tank 3 by welding.

[0058] Example 4

[0059] The difference between Example 4 and Example 1 is that the cable 12 is a chain.

[0060] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.

Since the center of gravity of the loading platform (7) is on the other side of the rotation center, and the stop block (1101) that unidirectionally prevents the loading platform (7) from rotating is in an unobstructed position, the loading platform (7) begins to rotate downward under its own weight.
