Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a log sawing and feeding device. Background Technology

[0002] A saw trolley, also known as a sawmill, is a device used to cut logs into slices. The band saw trolley is one of the main pieces of equipment in woodworking machinery. It uses a trolley to move the wood in a straight line, and the band saw blade cuts the wood in a straight line, facilitating the cutting of large logs and turning them into usable profiles. The feed end of the saw trolley is usually equipped with a sawing platform frame, on which the logs to be cut are fed for subsequent cutting.

[0003] The existing Chinese patent with publication number CN214026093U discloses an automatic log sawing and feeding device. The existing technical solution has the following defects: Although the operator only needs to push the logs from the preparation table into the conveyor table one by one, and the logs are transported and fed by the conveyor rollers on the conveyor table; baffles are designed on both sides of the conveyor table to prevent the logs from falling off the conveyor table during the feeding process. The height of the baffle on the side away from the feeding channel is greater than the height of the baffle on the other side, which can effectively prevent the logs from falling off the conveyor table due to excessive impact force during the feeding process, the log feeding in the above technical solution relies entirely on manual pushing one by one. This not only increases the labor intensity of the operator, but also easily leads to a decrease in efficiency due to fatigue during continuous operation. Secondly, the manual pushing method is difficult to guarantee the stability of the feeding rhythm, which may cause uneven load on the conveyor table, thereby affecting the overall conveying efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a log sawing and feeding device that can automatically feed and transport timber, thereby improving its working efficiency and solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a log sawing and feeding device, comprising a storage box, hydraulic push rods fixedly installed on both sides of the bottom upper surface of the storage box, and a support platform fixedly connected to the output end of the hydraulic push rods; a fixed plate is provided on one side of the support platform, and a motor is fixedly installed on one side surface of the fixed plate; a screw is fixedly connected to the output end of the motor, and a moving block is threadedly connected to the screw; a connecting block is provided on the top surface of the moving block through a connecting groove opened on the top surface of the support platform, and a push plate is fixedly connected to the top of the connecting block; a limiting rod is provided inside the support platform through the moving block; a mounting frame is provided on one side of the storage box, and a conveyor belt is fixedly installed on the mounting frame; a connecting plate is inclined between the storage box and the mounting frame, and side plates are provided on both sides of the top surface of the connecting plate.

[0006] Preferably, a horizontal plate is provided between the mounting brackets below the conveyor belt, and a cleaning brush is provided above the horizontal plate. Insert rods are provided on both sides of the bottom surface of the cleaning brush through the horizontal plate, and a spring is sleeved on the outer surface of the insert rods between the cleaning brush and the horizontal plate.

[0007] Preferably, the length of the cleaning brush is the same as the width of the conveyor belt, and the cleaning brush is matched with the conveyor belt.

[0008] Preferably, the support platform is matched with the storage box, and the moving block is slidably connected to the limiting rod.

[0009] Preferably, a first baffle is fixedly connected to one side of the top surface of the mounting bracket, and a second baffle is fixedly connected to one side of the top surface of the mounting bracket located on the connecting plate.

[0010] Preferably, the connecting block and the connecting groove are rectangular structures, and the connecting block and the connecting groove are slidably connected.

[0011] Preferably, a hydraulic pump is fixedly installed on one side surface of the hydraulic push rod, and a hydraulic tank is provided at the middle position of the bottom upper surface of the storage box. The hydraulic pump is connected to the hydraulic tank through a liquid extraction pipe, and the hydraulic pump is connected to the hydraulic push rod through a liquid delivery pipe.

[0012] Preferably, the pusher plate is matched with the storage bin.

[0013] Compared with the prior art, this utility model provides a log sawing and feeding device, which has the following beneficial effects:

[0014] (1) In this utility model, the wood to be processed is neatly stacked in the storage box. After the hydraulic push rods on both sides of the bottom of the storage box are started, the hydraulic push rods drive the support platform to move horizontally, realizing the initial pushing of the wood. Then the motor on the side of the fixed plate is started. The motor drives the screw to rotate. Under the guidance and constraint of the limit rod, the moving block moves linearly along the screw and drives the push plate to move synchronously through the connecting block, thereby pushing the wood on the support platform smoothly onto the inclined connecting plate. After the wood passes through the connecting plate, it automatically slides down to the conveyor belt. Finally, the conveyor belt completes the entire automated feeding process. This device realizes the full-process mechanized operation of wood from storage to conveying through the coordinated cooperation of hydraulic pushing and screw transmission mechanism. It effectively solves the problems of high labor intensity and low efficiency of manual feeding. It has a high degree of automation and is conducive to improving its working efficiency.

[0015] (2) In this utility model, the side plates set on both sides of the top of the connecting plate form a guide channel, which effectively prevents the wood from shifting when it slips through the transition, and ensures that the wood enters the conveyor belt accurately. The first baffle and the second baffle configured on the mounting frame on the conveyor belt constitute double protection, which continuously constrains the displacement of the wood during the conveying process and ensures the stability of the transport trajectory. The cleaning mechanism consists of a cleaning brush, a horizontal plate, a plug rod and a spring. The pre-tensioning force of the spring makes the cleaning brush always stick to the surface of the conveyor belt. Under the limiting support of the horizontal plate and the plug rod, the accumulated wood chips and dust during the conveying process can be efficiently removed, which significantly improves the practicality and reliability of this device.

[0034] Working principle:

[0035] In use, the timber to be processed is neatly stacked in the storage bin 1. After activating the hydraulic push rods 2 on both sides of the bottom of the storage bin 1, the hydraulic push rods 2 drive the support platform 4 to move horizontally, realizing the initial pushing of the timber. Then, the motor 21 on the side of the fixed plate 20 is activated. The motor 21 drives the screw 8 to rotate. Under the guidance and constraint of the limit rod 9, the moving block 7 moves linearly along the screw 8, and drives the push plate 3 to move synchronously through the connecting block 5, thereby smoothly pushing the timber on the support platform 4 onto the inclined connecting plate 11. After passing through the connecting plate 11, the timber automatically slides down to the conveyor belt 13, and finally the conveyor belt 13 completes the automated feeding. Throughout the process, the side plates 10 on both sides of the top of the connecting plate 11 form a guide channel, effectively preventing the wood from shifting during the transition and ensuring that the wood accurately enters the conveyor belt 13. The first baffle 14 and the second baffle 19 configured on the mounting frame 12 on the conveyor belt 13 provide double protection, continuously restraining the displacement of the wood during the conveying process and ensuring the stability of the transport trajectory. The cleaning brush 15 is kept in contact with the surface of the conveyor belt 13 by the pre-tension of the spring 16. Under the limiting support of the cross plate 18 and the insertion rod 17, the accumulated wood chips and dust during the conveying process can be efficiently removed, which significantly improves the practicality and reliability of the device.
