[0002] In a wood processing factory, after the wood raw materials are transported back from the outside world, it is necessary to clean the wood raw materials first. The purpose of doing this is to preliminarily remove impurities such as sediment and wood chips on the surface of the wood raw materials to facilitate subsequent processing. The traditional method is to put the wood raw materials into a cleaning tank filled with clean water and use the clean water to soak and clean. However, on the one hand, since the wood raw materials usually float on the water surface, it is not conducive to the comprehensive cleaning of the wood raw materials. On the other hand, the sundries washed off may adhere to the surface of the wood raw materials again when the wood raw materials are taken out, affecting the cleaning quality.

DETAILED DESCRIPTION

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] like Figure 1 As shown, a wood material cleaning device comprises a cleaning tank 1; a drain valve 2 is connected to the bottom of the cleaning tank 1; columns 3 are fixed on the left and right sides of the outside of the cleaning tank 1 respectively; the upper ends of the two columns 3 are connected by a crossbeam 4 arranged along the left and right directions; a pressure rod 5 is arranged in parallel below the crossbeam 4 along the left and right directions; the crossbeam 4 and the pressure rod 5 are connected by a first telescopic device 6; the first telescopic device 6 is used to drive the pressure rod 5 to move up and down in the cleaning tank 1; a plurality of wood lifting mechanisms for lifting wood are distributed from left to right inside the cleaning tank 1; a wood flushing mechanism is arranged on the cleaning tank 1; the coverage length of the pressure rod 5 in the left and right directions exceeds the lifting length of the wood lifting mechanism in the left and right directions;

[0018] like Figure 1-2 As shown, the wood lifting mechanism comprises support columns 7 respectively fixed to the front and rear sides of the bottom of the cleaning tank 1; the support columns 7 are arranged vertically; a sleeve 8 is slidably sleeved on the outer side of the upper part of the support column 7; a lifting claw 9 for lifting wood is fixed on the upper end of the sleeve 8; a compression spring 10 is sleeved on the outside of the support column 7; the lower end of the compression spring 10 is connected to the bottom end of the cleaning tank 1, and the upper end of the compression spring 10 is connected to the lower end of the sleeve 8;

[0019] like Figure 2 As shown, the wood washing mechanism includes a mounting bar 11 which is arranged across the upper end of the cleaning tank 1 in the left-right direction; the mounting bar 11 is slidably connected to the upper end of the cleaning tank 1 in the front-back direction; a water tank 12 is fixed to the upper end of the mounting bar 11; the water tank 12 is connected to the external water supply system through a water injection pipe 13; a plurality of nozzles 14 for spraying water downward are fixed from left to right at the lower end of the mounting bar 11; the nozzles 14 are connected to the water tank 12.

[0020] First, the wood material to be cleaned is placed on the wood lifting mechanism, and the front and rear sides of the wood material are lifted respectively by the front and rear lifting claws 9, so that the wood material can be inside the cleaning tank 1 and does not touch the bottom surface of the cleaning tank 1. Then, clean water is added to the cleaning tank 1, and the amount of water added is controlled so that the water surface can soak a part of the wood material, but the wood material will not float up to separate from the lifting claws 9.

[0021] Subsequently, the pressing rod 5 is pushed downward by the first expander 6. The pressing rod 5 presses the wood raw material downward, and the wood raw material presses the lifting claws 9, causing the sleeve 8 to slide down along the support column 7 and compressing the compression spring 10. Through this process, the wood raw material can be fully immersed in water, achieving a comprehensive cleaning of the surface of the wood raw material. Of course, due to the elastic recovery of the compression spring 10 and the buoyancy of water, after the first expander 6 retracts and the pressing rod 5 moves upward, the wood raw material can return to its original height. Thus, through multiple telescopic actions of the first expander 6, multiple rinsing actions on the wood raw material can be achieved, which is more conducive to the detachment of sundries on the surface of the wood raw material.

[0022] After the soaking and rinsing are completed, the water in the cleaning tank 1 is drained by opening the drain valve 2. At this time, the gradual reduction of water will not cause the wood raw material to touch the bottom surface of the cleaning tank 1, thereby avoiding the contact between the sundries remaining on the bottom surface of the cleaning tank 1 and the wood raw material, ensuring the effectiveness of the cleaning effect.

[0023] After the above operations are completed, the external water supply system injects water into the water storage tank 12 through the water injection pipe 13, sprays water downward through the nozzle 14, and then slides along the cleaning tank 1 through the mounting strip 11, so that the nozzle 14 sprays water from above the wood raw material, realizing the flushing of the surface of the wood raw material, and effectively washing away the sundries attached to the surface of the wood raw material with the flowing water during the drainage of the cleaning tank 1, further improving the quality of the cleaning of the surface of the wood raw material.

[0024] As Figure 1 shown, a wood pushing mechanism is provided at the front part of the cleaning tank 1; the wood pushing mechanism includes a push plate 15 arranged horizontally at the front side inside the cleaning tank 1 in the left - right direction; a second expander 16 is fixed at the front end outside the cleaning tank 1; the telescopic end of the second expander 16 is horizontally backward and fixed to the push plate 15; the covering length of the push plate 15 in the left - right direction exceeds the lifting length of the wood lifting mechanism in the left - right direction; the second expander 16 is used to push the push plate 15 to move the wood backward.

[0025] When rinsing and cleaning the wood raw material, the position where the wood raw material contacts the lifting claws 9 may be blocked, resulting in incomplete cleaning. At this time, the second expander 16 can be used to push the push plate 15 backward, so that the push plate 15 appropriately moves the wood raw material backward, thereby moving the blocked part away, avoiding the problem of cleaning dead corners.

[0026] As Figure 1 shown, a first telescopic guide rod 17 is vertically connected between the cross beam 4 and the pressing rod 5; a second telescopic guide rod 18 is connected between the push plate 15 and the front end of the cleaning tank 1. The first telescopic guide rod 17 and the second telescopic guide rod 18 play a guiding role, respectively improving the stability of the pressing rod 5 and the push plate 15 during movement.

[0027] As Figure 1-2As shown, a driving motor 19 is fixedly installed at the front end of the outer wall of the cleaning tank 1; the output end of the driving motor 19 is horizontally backward and coaxially fixed with a lead screw 20; the lead screw 20 is arranged in the front-back direction; the lead screw 20 is rotatably connected to the cleaning tank 1; a connecting rod 21 is fixedly installed at the lower end of the installation strip 11; the connecting rod 21 is threadedly sleeved on the lead screw 20.

[0028] The driving motor 19 can drive the lead screw 20 to rotate, and then drive the installation strip 11 to move back and forth through the connecting rod 21, so as to realize the front-back movement and spraying of the spray head 14. There is no need for manual driving of the installation strip 11 to move, which improves efficiency and saves labor; by switching the forward and reverse rotation of the driving motor 19, the forward and backward movement of the installation strip 11 can be changed.
