[0048] like Figures 1 to 5 As shown, the embodiment of the utility model provides a hammer crushing device. The hammer crushing device is suitable for crushing wooden edge strip waste. The hammer crushing device can include a first motor 1, a box body 2, a crushing shaft 3 and a negative pressure device 4.

[0049] Furthermore, the box body 2 has a accommodating chamber 21. A feed port 22 may be provided on the box body 2. The feed port 22 may be provided above the box body 2. A feed hopper 5 may be installed above the box body 2. After the feed hopper 5 is installed above the box body 2, the wooden strips may enter the feed port 22 through the feed hopper 5. A discharge port 23 may be provided at the bottom of the box body 2, and the material obtained after crushing may be transferred to the outside of the accommodating chamber 21 through the discharge port 23. The crushing shaft 3 may be arranged in the accommodating chamber 21, and may be connected to the first motor 1 in a transmission manner. The first motor 1 may be arranged outside the box body 2, and the first motor 1 may be connected to the crushing shaft 3 arranged in the accommodating space through a conveyor belt 6. The crushing shaft 3 may pass through the side wall of the box body 2 from the accommodating space and be connected to the conveyor belt 6. A vertical extension (such as Figure 4 The first motor 1 drives the conveyor belt 6 to move, so that the conveyor belt 6 can drive the crushing shaft 3 to rotate, so as to crush the wooden edge strips by the hammer head 31. The negative pressure device 4 can be connected to the accommodating chamber 21 through the feed opening 23, and the negative pressure device 4 provides negative pressure to the feed opening 23, so that the material obtained after crushing can be sucked out by the negative pressure device 4. The negative pressure device 4 may include an exhaust fan, such as a reciprocating vacuum pump, a water ring vacuum pump, and a jet vacuum pump. The negative pressure device 4 may also include a longer transmission pipeline. The negative pressure device 4 may be connected to the feed opening 23 through a transmission pipeline. The transmission pipeline may be connected to the exhaust fan, and the other side of the exhaust fan may be connected to the collecting device to collect the crushed material. Since the material obtained after the wooden edge strips are crushed is relatively light, the material can be extracted and collected by exhausting air with an exhaust fan.

[0050] According to the embodiment of the utility model, by crushing the edge strip waste in the accommodating chamber 21 with the hammer 31 on the crushing shaft 3, the edge strip waste can be turned into reusable materials. By providing a negative pressure device 4 in communication with the accommodating chamber 21 and using the negative pressure device 4 to provide negative pressure to the lower feed port 23, the edge strip waste can be crushed and the obtained material can be extracted and collected, thereby improving the utilization rate of the wood. In addition, by connecting the negative pressure device 4 with the accommodating chamber 21, the material collection process is in a relatively closed space, which can avoid dust pollution.

[0051] According to the embodiment of the utility model, the box body 2 may also be provided with an air inlet 24. When the negative pressure device 4 absorbs the material, the air inlet 24 may be used to allow external gas to flow into the accommodating chamber 21, thereby providing gas conditions for the negative pressure device 4 to work.

[0052] like Figure 5As shown, according to an embodiment of the utility model, a discharge chute 25 is provided at a position of the box body 2 corresponding to the air inlet 24. In the process that the air inlet 24 allows external gas to flow into the accommodating chamber 21, the crushed material may splash out from the air inlet 24. By providing the discharge chute 25 at a position corresponding to the air inlet 24, the discharge chute 25 can receive the material splashed from the air inlet 24, thereby further reducing dust pollution and maintaining the working environment of the workshop.

[0053] According to the embodiment of the utility model, a material discharge channel 26 is formed at the bottom of the box body 2, and the material discharge channel 26 is connected to the accommodating chamber 21, and the material discharge port 23 is opened at one end of the material discharge channel 26 close to the accommodating chamber 21. A material net is clamped at a position corresponding to the material discharge port 23 in the box body 2. By setting the size of the mesh of the material net, the material can be filtered to allow the material that meets the requirements to pass through the material net and enter and exit the accommodating chamber 21. For example, the size of the mesh of the material net can be set to 5 mm to allow materials less than or equal to 5 mm to enter the material discharge channel 26, and materials larger than 5 mm continue to be crushed in the accommodating chamber 21.

[0054] According to the embodiment of the utility model, one end of the material discharge channel 26 away from the material discharge port 23 is sealed and connected to the negative pressure device 4 through the flange 7. The negative pressure device 4 is detachably mounted on the box body 2 to facilitate the maintenance of the negative pressure device 4 and the box body 2.

[0055] According to an embodiment of the utility model, the hammer milling device further includes a hammer rod 32. One end of the hammer rod 32 is mounted on the milling shaft 3 and extends in a direction perpendicular to the milling shaft 3. A hammer head 31 is mounted on the other end of the hammer rod 32. The hammer head 31 may be a cylindrical shape with a high top middle and a low outer side. The material of the hammer head 31 and the hammer rod 32 may be the same, which can increase the thickness of the hammer head 31 and extend the service life of the hammer head 31.

[0056] Figure 6 The figure schematically shows the position relationship between the feed shaft and the press shaft according to the embodiment of the utility model.

[0057] like Figures 1 to 6 As shown, according to an embodiment of the utility model, the hammer milling device further includes a second motor 8 and a feed shaft 9. The feed shaft 9 is installed at the bottom of the feed port 22 and can be connected to the second motor 8 by transmission. The second motor 8 can be installed on the top of the box body 2. The second motor 8 can be connected to the feed shaft 9 by transmission through a conveyor belt 6. The output shaft of the second motor 8 can be provided with a reducer, and the second motor 8 drives the feed shaft 9 to rotate after being decelerated by the reducer.

[0058] The feed shaft 9 is provided with an axial distribution (such as Figure 6In the case where the second motor 8 drives the feed shaft 9 to rotate in the feeding direction, the teeth drive the edge strip waste into the accommodating chamber 21. The feed hopper 5 can be connected to the feed port 22, and the bottom plate of the feed hopper 5 can be tilted. After the external feeding device conveys the edge strip waste to the feed hopper 5, the edge strip waste enters the feed port 22 based on the tilt of the feed hopper 5. In the case where the second motor 8 drives the feed shaft 9 to rotate in the feeding direction, that is, drives the feed shaft 9 to rotate toward the accommodating chamber 21 (such as perpendicular to the Figure 3 The teeth can drive the edge strip waste to move toward the accommodating chamber 21, thereby entering the accommodating chamber 21.

[0059] According to an embodiment of the utility model, the hammer milling device may further include a pressing shaft 10. The pressing shaft 10 may be installed at the feed port 22 and located on the upper portion of the feed shaft 9. In the process of the feed shaft 9 driving the edge strip waste to rotate, the pressing shaft 10 rotates along with the edge strip waste, and the pressing shaft 10 and the feed shaft 9 cooperate to drive the edge strip waste into the accommodating chamber 21. By providing the pressing shaft 10, it is possible to prevent the edge strip waste from being squeezed out of the feed port 22 in the process of the feed shaft 9 driving the edge strip waste to move toward the accommodating chamber 21.

[0060] According to an embodiment of the utility model, the material discharge channel 26 includes a first portion 261 and a second portion 262. The first portion 261 is connected to the accommodating chamber 21 and extends perpendicular to the pulverizing shaft 3. The second portion 262 is connected to the first portion 261 and extends parallel to the pulverizing shaft 3. The second portion 262 is configured to be connected to the negative pressure device 4. The opening length of the first portion 261 close to one end of the accommodating chamber 21 is greater than the opening length of the first portion 261 close to one end away from the accommodating chamber 21, so as to avoid the accumulation of materials near the accommodating chamber 21, thereby improving the transmission efficiency of the materials.

[0061] According to the embodiment of the utility model, by crushing the edge strip waste in the accommodating chamber 21 with the hammer 31 on the crushing shaft 3, the edge strip waste can be turned into reusable materials. By providing a negative pressure device 4 in communication with the accommodating chamber 21 and using the negative pressure device 4 to provide negative pressure to the lower feed port 23, the edge strip waste can be crushed and the obtained material can be extracted and collected, thereby improving the utilization rate of the wood. In addition, by connecting the negative pressure device 4 with the accommodating chamber 21, the material collection process is in a relatively closed space, which can avoid dust pollution.
