Description

Technical Field

[0001] This utility model relates to the field of wood chip processing technology, specifically a wood chip pulverizing device. Background Technology

[0002] Solid wood particleboard is a type of engineered wood product made from wood chips or other lignocellulosic materials, bonded together with adhesives under heat and pressure. The surface of solid wood particleboard is melamine-faced, and its cross-section has a honeycomb pattern. As a new type of high-end environmentally friendly substrate, it has begun to be widely used.

[0003] In the process of wood chip processing, crushing equipment is usually required for crushing. However, when the crushed wood chips need to be removed, the current crushing equipment is slow because the wood chips have poor flowability and the feeding opening of the crushing box is relatively small. In addition, blockage is also prone to occur.

[0004] Therefore, we propose a wood chip pulverizing device to solve the problems mentioned above. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0026] A wood chip pulverizing device includes a pulverizing box 1 mounted on a mounting frame 17. It should be noted that the bottom of the pulverizing box 1 has a gap of at least 1.5m with the ground to facilitate the removal of wood chips from the pulverizing box 1. The top and bottom of the pulverizing box 1 are open. A box cover 2 is installed on the opening at the top of the box cover 2, and a drive source 3, which is a motor, is installed on the top of the box cover 2. A pulverizing shaft 4 is installed through the output shaft of the drive source 3, and several pulverizing components 5 are equidistantly mounted on the pulverizing shaft 4. These multiple pulverizing components 5 are located inside the pulverizing box 1 and operate at high speed. During rotation, the wood chips inside the crushing chamber 1 are crushed. The opening at the bottom of the crushing chamber 1 is a discharge port for discharging the crushed wood chips. A drive assembly 6 is installed on the outer surface of the crushing chamber 1. It should be noted that there can be one or two drive assemblies 6. A base plate 7 is installed on the telescopic end of the drive assembly 6. The base plate 7 can seal the opening at the bottom of the crushing chamber 1. Under normal circumstances, the base plate 7 and the opening at the bottom of the crushing chamber 1 are in a sealed state, which can ensure the crushing of wood chips. When discharging, the base plate 7 opens from the opening at the bottom of the crushing chamber 1 to discharge the crushed material.

[0027] The upper part of the box cover 2 is equipped with an "L"-shaped material inlet 8, and the bottom end of the material inlet 8 is connected to the inside of the box cover 2. Through the setting of the material inlet 8, it can be connected to an external screw conveyor (not shown in the figure), and the screw conveyor can transport wood chips into the inside of the crushing box 1. The feed port of the material inlet 8 is equipped with a first flange 9, which serves to fix the screw conveyor.

[0028] The outer surface of the crushing chamber 1 is equipped with a drying port 10, which is connected to the interior of the crushing chamber 1. The drying port 10 can be connected to a drying device (not shown in the figure). With the drying device, the wood chips can be dried during the crushing process. A second flange 11 is also fixed to one end of the drying port 10. The drying device can be fixed by the second flange 11. It should be noted that the cover 2 is provided with several exhaust ports 12. The exhaust ports 12 are used to discharge the gas in the crushing chamber 1, so that the air in the crushing chamber 1 can flow.

[0029] In detail: The crushing component 5 includes a fixed sleeve 51, which is fixed on the crushing shaft 4. Several blades 52 are fixed at equal intervals along the circumferential direction on the fixed sleeve 51. When the fixed sleeve 51 drives the blades 52 to rotate at high speed, it can crush the wood chips in the crushing box 1.

[0030] In detail: Several "L"-shaped fixing plates 18 are fixed at equal intervals along the circumference on the outer surface of the crushing box 1. Fixing bolts 19 pass through the fixing plates 18 and are threadedly connected to the threaded holes (not shown in the figure) opened on the mounting bracket 17. Through the cooperation of the fixing plates 18 and the fixing bolts 19, the crushing box 1 is fixed, preventing the crushing box 1 from shaking during use and improving the stability of the crushing device.

[0031] In detail: The outer surface of the top of the crushing box 1 and the outer surface of the bottom of the box cover 2 are respectively equipped with annular protrusions 15. When the box cover 2 is closed with the crushing box 1, the two annular protrusions 15 can be fastened by the fastening bolts 16 to prevent the box cover 2 and the crushing box 1 from shaking relative to each other, thereby further improving the stability of the crushing device.

[0032] A rotating seat 13 is fixed on the outer surface of the base plate 7, and a connecting ear 14 is fixed on the lower part of the crushing box 1. The rotating seat 13 is rotatably mounted on the connecting ear 14. The base plate 7 can rotate on the crushing box 1.

[0033] Specifically: the drive assembly 6 includes an electric telescopic rod 61, and a U-shaped mounting plate 62 is fixed on the electric telescopic rod 61. The U-shaped mounting plate 62 has a through hole, and the connecting shaft 63 passes through the through hole and connects to the fixing hole on the mounting base 64. Through the cooperation of the U-shaped mounting plate 62 and the connecting shaft 63, the electric telescopic rod 61 can rotate on the crushing box 1. The mounting base 64 is fixed on the outer surface of the crushing box 1. A rotating sleeve 65 is fixed to the telescopic end of the electric telescopic rod 61, and the rotating sleeve 65 is rotatably mounted on the rotating shaft 66. The rotating shaft 66 is fixed to one end of the L-shaped rotating plate 67, and the L-shaped rotating plate 67 is fixed to the outer surface of the base plate 7. Through the cooperation of the rotating sleeve 65, the rotating shaft 66 and the L-shaped rotating plate 67, the base plate 7 can rotate at the telescopic part of the electric telescopic rod 61.

[0034] After the screw conveyor transports the wood chips into the crushing box 1 through the material inlet 8, the drive source 3 is turned on. The drive source 3 drives several crushing components 5 to rotate at high speed through the crushing shaft 4. The crushing components 5 can crush the wood chips in the crushing box 1. During the crushing process, the drying device can also be turned on. The heat released by the drying device can enter the interior of the crushing box 1 through the drying port 10 and dry the crushed wood chips. This can be done simultaneously, improving the efficiency of wood chip processing.

[0035] After the wood chips are crushed, the cargo trolley (not shown in the figure) can be placed inside the crushing box 1 and directly below it. The electric telescopic rod 61 is activated, and the telescopic end of the electric telescopic rod 61 extends and pushes the rotating shaft 66 downward. The rotating shaft 66 drives the bottom plate 7 to flip downward through the "L"-shaped rotating plate 67, so that the opening at the bottom of the crushing box 1 can be opened. The crushed wood chips can fall quickly into the interior of the cargo trolley, thereby speeding up the unloading efficiency and reducing the likelihood of blockage. The cargo trolley can then transport the wood chips to the next processing stage for further processing.

[0036] It should be noted that the screw conveyor, drying device, and cargo trolley in this application are all prior art. The specific structure and working principle of the screw conveyor, drying device, and cargo trolley in this application are described in detail.
