[0003] When the drum chipper is in operation, the wood is placed on the feeding mechanism, which feeds the wood between the knife roller and the bottom knife. The flying knife on the knife roller chips the material through the rotation of the knife roller. In the prior art, the feeding mechanism usually sets two upper and lower parallel feeding rollers to achieve the purpose of feeding. The upper feeding roller presses the wood to limit its position, thereby preventing the wood from being displaced by force during cutting. However, the knife roller generates impact force on the wood during cutting, and the reaction force of the wood acts on the feeding mechanism to cause impact force on the mechanism, which can easily cause damage to the feeding mechanism. Since the feeding rollers are designed to be parallel, it is difficult to achieve the purpose of directional calibration and transportation of the wood during the feeding process, so that wood of different specifications is easily offset after being pushed, which will cause cutting errors and affect the use effect of the drum chipper. Utility Model Content

[0007] As a further solution of the utility model: the driving roller is arranged obliquely in the feeding trough, and the two driving rollers form a V-shaped structure.

[0008] As a further solution of the utility model: a plurality of anti-skid particles are arranged outside the rubber leather sleeve, a side plate is installed on the top end of the driving roller, and the side plate is fixed to the inner side wall of the feeding trough.

[0009] As a further solution of the utility model: the adjustment component includes a top plate, the top plate is fixed on the machine body, an electric hydraulic rod is arranged inside the top plate, and the bottom end of the electric hydraulic rod passes through the machine body and is connected to a cross plate.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a drum chipper feeding device, comprising a base 1, a body 2 is arranged on the base 1, a material table 11 is installed on one side of the body 2 close to the feeding assembly 4, and a plurality of guide wheels 12 are installed on the material table 11. Due to the guide wheels 12, when wood is put on the material table 11, friction can be reduced when the wood is pushed to move, so that the position of the wood can be transferred easily;

[0022] A feeding trough 3 is provided on one side of the machine body 2. Two feeding assemblies 4 are installed at the bottom of the feeding trough 3. The feeding assembly 4 includes a driving roller 401. The driving roller 401 is tiltedly arranged in the feeding trough 3. The two driving rollers 401 form a V-shaped structure. Due to the driving roller 401, the wood is always kept between the two driving rollers 401 during the movement, which is convenient for directional transportation of the wood and can also meet the feeding work of wood of different specifications.

[0023] The driving roller 401 is provided with a rubber cover 402, and the rubber cover 402 is provided with a plurality of anti-skid particles 403. A side plate 405 is installed on the top of the driving roller 401, and the side plate 405 is fixed to the inner wall of the feeding trough 3. Because the rubber cover 402 and the anti-skid particles 403 are provided, when the wood is located between the two driving rollers 401, the rubber cover 402 serves to buffer and support the wood, preventing the driving roller 401 from being deformed by instantaneous impact force, and with the provision of the anti-skid particles 403, slipping is prevented during the transportation of the wood, thereby improving the transportation stability;

[0024] The bottom end of the driving roller 401 is sleeved with a bearing 5, and the bearing 5 is clamped on the bottom of the feeding trough 3;

[0025] The bottom end of the driving roller 401 passes through the bearing 5 and is fixedly connected with a bevel gear 1 6. The two bevel gears 1 6 are meshed with each other, and a bevel gear 2 8 is meshed on one of the bevel gears 1 6. A motor 7 is fixed to the bottom of the bevel gear 2 8. The motor 7 is installed in the machine body 2. An adjustment component 9 is installed on the machine body 2. The adjustment component 9 includes a top plate 901. The top plate 901 is fixed on the machine body 2. An electric hydraulic rod 902 is arranged in the top plate 901. The bottom end of the electric hydraulic rod 902 passes through the machine body 2 and is connected with a cross plate 903. By setting the electric hydraulic rod 902, it is convenient to adjust the positions of the cross plate 903 and the two pressing rollers 102 to meet the purpose of limiting support for wood of different specifications.

[0026] The bottom of the adjusting component 9 passes through the top of the machine body 2 and is connected to two clamping components 10. The two clamping components 10 are located above the driving roller 401. The clamping component 10 includes a bracket 101, and a pressure roller 102 is installed in the bracket 101. A connecting shaft 103 is sleeved on the top of the bracket 101, and the connecting shaft 103 is installed on the bottom of the cross plate 903. Snap rings 104 are respectively clamped on both sides of the outside of the connecting shaft 103, and a coil spring 105 is fixed between the retaining ring 104 and the inner wall of the bracket 101. The coil spring 105 is sleeved on the outside of the connecting shaft 103. Because the coil spring 105 is provided, when the pressure roller 102 rotates outside the connecting shaft 103, the coil spring 105 provides a reverse supporting force to the pressure roller 102, so that the pressure roller 102 can be close to the wood, thereby improving the supporting effect of the pressure roller 102 on the wood.

[0027] The working principle of the utility model is:

[0028] When in use, the wood is placed on the material table 11, and the wood is pushed so that it is located between the two driving rollers 401. The electric hydraulic rod 902 is controlled to extend so that it drives the cross plate 903 to move downward, and the cross plate 903 drives the two pressure rollers 102 to move downward and contact with the top of the wood, thereby playing a role in squeezing and limiting the wood. In the process of the two pressure rollers 102 squeezing the wood, the pressure rollers 102 can rotate around the connecting shaft 103, so that the two pressure rollers 102 are opened in an eight-shaped shape, so that the force on the wood is balanced, and the action of the outer coil spring 105 of the connecting shaft 103 is cooperated to provide a downward squeezing force to the pressure rollers 102, and the motor 7 drives the bevel gear 2 8 to rotate, and the bevel gear 2 8 drives the bevel gear 1 6 to rotate. Since the two bevel gears 1 6 are meshed, the two bevel gears 1 6 can synchronously drive the two driving rollers 401 to rotate in opposite directions, and then the wood can be transported to the left, thereby achieving the purpose of feeding the wood.
