Description

Technical Field

[0001] The utility model relates to the technical field of firewood splitters, in particular to a novel firewood splitter. Background Art

[0002] As the name suggests, a wood splitter is a device that uses the sharp end of an instrument to split wood materials, thereby reducing the wood to smaller pieces. It is commonly found in the wood processing industry. Since some wood has a large diameter, it is extremely inconvenient to transport or process it, so a wood splitter is needed to split the wood.

[0003] After searching, a wood splitter is disclosed in the utility model patent with the Chinese patent publication number CN221540130U. The wood splitter in the utility model patent also adopts a push-type method, which is to push the pressure plate by a hydraulic jack to drive the wood to move to the side of the cutter to perform the wood splitting operation;

[0004] However, in combination with the operation process of the wood splitter, it can be seen that the hydraulic jack requires manual operation and control, and still generates a certain amount of operation, and it is impossible to automatically control the propulsion stroke of the hydraulic jack. At the same time, when the horizontal frame of the wood splitter pushes the logs through the hydraulic jack, the logs may roll away from the work surface, causing injuries to workers. Therefore, the structure of the wood splitter needs to be further improved, and thus a new wood splitter is proposed. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present invention provides a new type of wood splitter, which has the advantages of automatically controlling the propulsion stroke of the wood splitter and assisting in guiding the wood, solving the problem that the wood splitter in the above-mentioned background technology cannot automatically control the propulsion stroke and cannot effectively prevent the wood from rolling.

[0006] To achieve the above object, the present invention provides the following technical solutions: a novel wood splitter, comprising a pushing platform, a power structure is provided on the top of the pushing platform, and a pushing assembly is provided on the outside of the pushing platform;

[0007] The power structure includes an oil tank fixedly mounted on the left side of the front of the pushing platform, an oil pump motor fixedly mounted on the top of the oil tank, a mounting bracket fixedly mounted on the left side of the top of the pushing platform, an oil cylinder fixedly mounted on the left side of the mounting bracket, an output end of the oil cylinder fixedly connected to a propulsion shaft, a control box fixedly mounted on the back of the mounting bracket, and an oil control valve fixedly mounted on the back of the mounting bracket;

The top of the control oil valve is fixedly connected with two No. 2 oil pipes, and the two No. 2 oil pipes are connected to the left side and the right side of the top of the oil cylinder at the end away from the control oil valve.

[0010] Furthermore, the top of the oil control valve is fixedly connected to a No. 3 oil pipeline, and the No. 3 oil pipeline is connected to the top of the oil tank at the end away from the oil control valve. The top of the oil tank is externally connected to a refueling pipe, and an operating lever is movably installed on the back of the oil control valve. A power box is fixedly installed on the front of the mounting frame, and the power box is electrically connected to the oil pump motor through a cable.

[0011] Furthermore, a number of operating buttons are provided on the back of the control box, and the control box is electrically connected to the oil pump motor. A cross-shaped splitting knife frame is fixedly installed on the top right side of the pushing platform, and the splitting knife frame includes a bevel vertical knife and a horizontal knife structure fixed on the front and rear sides of the bevel vertical knife.

A power box 8 is fixedly installed on the front of the mounting frame 203. A cross-shaped splitting knife frame 9 is fixedly installed on the top right side of the pushing platform 1. A reflector 10 is fixedly installed on the back of one of the slides 302. Material receiving frames 11 are welded on the front and back sides of the pushing platform 1.

[0028] The power structure 2 includes an oil tank 201 fixedly installed on the left side of the front of the pushing platform 1. An oil pump motor 202 is fixedly installed on the top of the oil tank 201. The oil pump motor 202 draws the hydraulic oil out of the oil tank 201. A mounting bracket 203 is fixedly installed on the left side of the top of the pushing platform 1. An oil cylinder 204 is fixedly installed on the left side of the mounting bracket 203. The output end of the oil cylinder 204 is fixedly connected to a propulsion shaft 205. The hydraulic oil provides power for the oil cylinder 204 to control the left and right telescopic movement of the propulsion shaft 205. A control box 206 is fixedly installed on the back of the mounting bracket 203. Control elements are arranged inside the control box 206, and operation buttons are installed on the back of the control box 206. A control oil valve 207 is fixedly installed on the back of the mounting bracket 203.

[0029] The pushing assembly 3 includes a pushing plate 301 that slides on the top of the pushing platform 1. The pushing plate 301 is used to push the wood. The bottom of the pushing plate 301 is fixedly connected to a slide 302. The slide 302 slides left and right along the outer side of the top of the pushing platform 1. A photoelectric proximity switch 303 is fixedly installed on the back of the pushing platform 1.

[0030] During implementation, follow these steps:

[0031] 1) First, place the wood on the top of the pusher 1, start the oil pump motor 202 and the oil cylinder 204, and use the manual operation lever 7 or operation button, or the photoelectric proximity switch 303 to control the stroke as needed;

[0032] 2) Then, by rotating the operating lever 7 or pressing the control button, the propulsion shaft 205 is controlled to move telescopically left and right;

[0033] 3) When the photoelectric proximity switch 303 is used for control, the slide 302 drives the push plate 301 to move left and right. When the reflector 10 enters the detection area of ​​the light emitting tube and the receiving port of the photoelectric proximity switch 303, the avalanche photodiode at the receiving port converts the optical signal into a corresponding electrical signal and transmits it to the control element of the control box 206 for signal processing;

[0034] 4) Finally, the control box 206 is connected to an external hydraulic control system to determine whether the propulsion shaft 205 has completed a round-trip propulsion stroke, thereby automatically controlling the propulsion stroke of the propulsion shaft 205.

[0035] according to Figure 1 and Figure 3 as well as Figure 4 As shown, the oil pump motor 202 draws the hydraulic oil out of the oil tank 201 through the oil extraction pipe connected to the front, and then sends it to the control oil valve 207 through the No. 1 oil pipe 4, and then sends it to the oil cylinder 204 through the No. 2 oil pipe 5 of the control oil valve 207, providing power for the oil cylinder 204. The output end of the oil cylinder 204 controls the left and right telescopic movement of the propulsion shaft 205.

[0036] according to Figure 2 and Figure 3 as well as Figure 6 As shown, by turning the operating lever 7 left or right, the hydraulic oil supplied to the oil cylinder 204 by the control oil valve 207 is changed, so that the oil cylinder 204 controls the propulsion shaft 205 to move left and right;

[0037] The control box 206 is internally installed with circuit components such as a control transformer, a micro signal processor, a relay module and a four-way remote control switch controller. The back of the control box 206 is installed with four operating buttons: a start button, a stop button, a forward button and a reverse button. The four operating buttons are controlled by the four-way remote control switch controller and can control four operating instructions respectively. The control box 206 controls the oil pump motor 202, changes the control oil valve 207 to send hydraulic oil to the oil cylinder 204, and can also realize the left and right movement of the propulsion shaft 205. This is a manual operation method.

[0038] according to Figure 3 and Figure 4 As shown, when the propulsion shaft 205 drives the push plate 301 to move left and right, every time the reflective sheet 10 enters the detection area of ​​the light emitting tube and receiving port of the photoelectric proximity switch 303, the avalanche photodiode of the receiving port can convert the optical signal into an electrical signal and transmit it to the micro signal processor of the control box 206 for processing, and determine whether the propulsion shaft 205 completes a round-trip propulsion stroke, and then control the oil valve 207 to send hydraulic oil to the oil cylinder 204, thereby realizing automatic control of the propulsion stroke of the propulsion shaft 205.

[0039] according to Figure 2As shown, the splitting knife frame 9 is composed of an inclined vertical knife 901 and two horizontal knives 902. The two horizontal knives 902 are moved 10 cm to the right, which can ensure the strength of the splitting knife frame 9 and move the wood to the rear of the inclined vertical knife 901 after splitting.

[0040] In summary, the new wood splitter extracts hydraulic oil through the oil pump motor 202 and sends the hydraulic oil into the oil cylinder 204. The propulsion shaft 205 is powered by the hydraulic oil to achieve the moving effect of propulsion and contraction. The control box 206 is installed on the back of the mounting frame 203. The back of the control box 206 is provided with an operation button, and the control element inside the control box 206 is electrically connected to the photoelectric proximity switch 303 through a cable. When the reflective sheet 10 on one of the slides 302 enters the detection area of ​​the two photoelectric proximity switches 303 respectively, the propulsion shaft 205 completes a round-trip propulsion stroke, or the operation button and the operating lever are directly used. 7. Since the control box 206 is electrically connected to the oil pump motor 202, it can control the hydraulic pressure supplied by the oil pump motor 202 to the oil cylinder 204, and realize the effect of dual control of the propulsion stroke of the oil cylinder 204 by manual operation and travel switch, thereby improving functional applicability and operation selectivity. The wood is placed on the top of the pushing platform 1, and then the pushing plate 301 is slid along the top of the pushing platform 1 to push the wood. A material receiving rack 11 is set on the front and back sides of the pushing platform 1 to receive the rolled wood to prevent the wood from rolling and causing injuries to the staff. This solves the problem that the wood splitter in the above-mentioned background technology cannot automatically control the propulsion stroke and cannot effectively prevent the wood from rolling.
