Description

Technical Field

[0001] This utility model relates to the technical field of vertical wood splitters, and in particular to a vertical wood splitter. Background Technology

[0002] Existing patent publication number (CN1799795A) discloses a portable wood splitter. The wood splitter includes a base having a pair of integral side parts; and a support member fixed to the integral side parts. The integral side parts and the support member form a support adapted to receive logs. The wood splitter also includes: a splitting wedge fixed to the support member; and a contact member capable of translating in a reciprocating motion adjacent to the support member to move the log. The wood splitter also includes a control assembly operated by a switch to drive the contact member in a reciprocating motion.

[0003] However, traditional wood splitters generally achieve splitting through hydraulic drive or inertial impact, which results in large kinetic energy impacts, a high probability of being uncontrollable, large reaction forces on mechanical joints, and wood flying everywhere, making them less safe.

[0004] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0005] A vertical wood splitter includes a movable base for the vertical wood splitter. A vertical frame is fixed to the movable base by bolts. A screw is rotatably mounted inside the vertical frame. The screw is driven by a drive motor located at the upper end of the vertical frame. A load-bearing slide is threadedly engaged with the screw. A rotating shaft is rotatably mounted at the front end of the load-bearing slide. A tapered threaded drill bit is connected to the lower end of the rotating shaft. The tapered threaded drill bit, under high-speed rotation, cuts into the wood through the tapered thread and splits the wood.

[0006] Preferably, the end of the carrying carriage is further provided with a geared motor, the output shaft of which is coaxially connected to the rotating shaft, and the geared motor drives the rotating shaft to rotate.

[0007] Preferably, the tapered threaded drill bit has a threaded hole inside, and the tapered threaded drill bit and the rotating shaft are threadedly connected and fixed.

[0008] Preferably, the load-bearing carriage is provided with ribs at the right angles to increase the rigidity of the load-bearing carriage.

[0009] Preferably, the lower end face of the movable base of the vertical wood splitter is equipped with casters at the four corners, and the casters are equipped with brakes.

[0010] Preferably, when the bearing carriage is at its lowest point of travel, the lower end of the tapered threaded drill bit is no more than five centimeters away from the ground.

[0011] The advantages and positive effects of this utility model are:

[0012] 1. Compared with equipment that uses inertial force to split wood, the working process of this application is more convenient. The conical spiral structure expands the cracks in the wood during rotation, causing the wood to expand. The process is more stable and controllable, and the safety is higher.

[0013] 2. Using this device, you can move it around and then align the tapered threaded drill bit with the wood to operate, eliminating the need to lift heavy wood and place it in the designated working position as with traditional equipment. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0019] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0020] like Figure 1As shown, the vertical wood splitter of this utility model includes a vertical wood splitter movable base 11. A vertical frame 10 is fixed to the vertical wood splitter movable base 11 by bolts. A screw is rotatably installed inside the vertical frame 10. The screw is driven by a drive motor 17 configured on the upper end of the vertical frame 10. A bearing slide 13 is threadedly engaged with the screw. A rotating shaft 15 is rotatably installed at the front end of the bearing slide 13. A tapered threaded drill bit 16 is connected to the lower end of the rotating shaft 15. The tapered threaded drill bit 16, under high-speed rotation, bites into the wood through the tapered thread and cracks the wood.

[0021] Preferably, the end of the supporting slide 13 is further provided with a reduction motor 14, the output shaft of the reduction motor 14 is coaxially connected to the rotating shaft 15, and the reduction motor 14 drives the rotating shaft 15 to rotate.

[0022] Preferably, the tapered threaded drill bit 16 has a threaded hole, and the tapered threaded drill bit 16 and the rotating shaft 15 are threadedly connected and fixed.

[0023] Preferably, the support carriage 13 is provided with a rib plate 18 at the right angle, which increases the rigidity of the support carriage 13.

[0024] Preferably, the lower end face of the vertical wood splitter's movable base 11 is provided with casters 12 at the four corners, and the casters 12 are equipped with brakes.

[0025] Preferably, when the bearing carriage 13 is at the lowest end of its stroke, the lower end of the tapered threaded drill bit 16 is no more than five centimeters away from the ground.

[0026] In practice: First, move the device according to the position of the wood, align the tip of the conical threaded drill bit 16 with the wood, and then drive the support slide 13 to descend through the drive motor 17 so that the lower end of the conical threaded drill bit 16 abuts against the wood. Start the reduction motor 14 to drive the conical threaded drill bit 16 to rotate. In this way, the conical threaded drill bit 16 extends into the wood under the action of the thread while the support slide 13 moves down, thereby splitting the wood by causing it to expand and crack. The process is more stable, controllable, safer, and more convenient.

[0027] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
