Background technique

In the roller conveyor of the prior art, the conveying roller is a smooth roller. During the material conveying process, the conveying roller has a small force on the material, and the material has a relatively large hysteresis phenomenon relative to the conveying roller, which affects the conveying efficiency; the conveying roller The spacing is small, and it is not easy to remove small debris. For the above reasons, when the roller conveyor of the prior art is used to feed the wood chipper, the conveying efficiency is low, and the foreign matter cannot be effectively removed, so that the foreign matter is also fed into the wood chipper, which affects the product quality.

Contents of the invention

The purpose of this utility model is to provide a toothed roller conveyor, which increases the force of the conveying roller on the material during the material conveying process, reduces the hysteresis of the material relative to the conveying roller, improves the conveying efficiency, and can conveniently eliminate Small debris, especially suitable for feeding wood chippers, improving product quality.

The purpose of this utility model is to realize through the following technical solutions:

A toothed roller conveyor, comprising a frame, at least two parallel conveying rollers that are rotatably arranged in the frame, a power source that drives the active conveying roller in the conveying roller to rotate, and transmits the power from the active conveying roller to the conveying roller The power transmission device of the driven conveying roller, the outer periphery of the conveying roller is evenly distributed with hobbing teeth; the gap between two adjacent conveying rollers is not greater than the minimum size of the conveying material.

The beneficial effects of the utility model are:

Compared with the roller conveyor of the prior art, when the above-mentioned toothed roller conveyor is used to transport materials, especially when the above-mentioned toothed roller conveyor is used to feed the wood chipper, the hobbing teeth uniformly distributed on the outer periphery of the conveying roller can be Effectively increase the force of the conveying roller on the material, reduce the hysteresis of the material relative to the conveying roller, and improve the conveying efficiency; the gap between two adjacent conveying rollers is not greater than the minimum size of the conveying material, and the size of the material can be smaller than The debris of the conveying material size falls from the gap between two adjacent conveyor rollers and leaves the conveyor. The larger debris can be manually removed, which avoids feeding the debris into the wood chipper and improves product quality.

As an improvement to the utility model, the power transmission device is a chain transmission device.

detailed description

Below in conjunction with accompanying drawing, take the conveyor that is used for wood chipper feeding as an example, the utility model is further described:

Referring to Fig. 1 and Fig. 2, this toothed roller conveyor includes a frame 8, at least two parallel conveying rollers that are rotatably arranged in the frame 8, and drive the power of the active conveying roller 10 in the conveying rollers to rotate Source 1, the power transmission device that transmits the power from the active conveying roller 10 to the driven conveying roller 11 in the conveying roller, and the outer circumference of the conveying roller is evenly distributed with hobbing teeth 4; the gap between two adjacent conveying rollers is not larger than the conveying material minimum size of .

The frame 8 includes a left side plate 3 and a right side plate 6 which are arranged oppositely, and an anchor 9 is fixedly connected with the left side plate 3 and the right side plate 6 .

There are at least two parallel conveying rollers arranged in the frame 8. The outer diameters of the five conveying rollers selected in the illustration are equal, and the axes of the five conveying rollers are coplanar. The space above the conveying rollers in the frame 8 constitutes the material channel 5 of the toothed roller conveyor.

Hobbing teeth 4 are evenly distributed on the outer periphery of the conveying roller. There are many ways to implement the uniform distribution of hobbing gears on the outer circumference of the conveying roller: directly set the hobbing gears on the conveying roller; evenly fasten the multiple flanges after the hobbing is arranged on the outer circumference of the conveying roller; A plurality of tooth blocks after milling teeth on the outer periphery are evenly fixedly connected to each outer surface of the prismatic conveying roller. Compared with the above-mentioned schemes, the third scheme which is easy to implement is adopted in this case. The figure shows that the center of the conveying roller is a square prism, and the four sides of the four prisms are evenly connected with the same tooth block 13, the direction of the hobbing 4 on the tooth block 13 is consistent, and the tooth tops of the hobbing 4 are collinear, so that The hobbing 4 is in contact with the material line, which is beneficial to increase the force of the hobbing 4 on the material. In addition, by adopting this solution, it is also easier to adjust the tooth shape of the tooth block 13 according to the shape of the conveyed material.

The gap between two adjacent conveying rollers is not greater than the minimum size of conveying materials.

Choose one conveying roller as the active conveying roller 10, and the rest are driven conveying rollers 11. The power source 1 provides power to the driving conveying roller 10 after being decelerated by the reducer 2 to drive the driving conveying roller 10 to run. A power transmission device is provided between the driving conveying roller 10 and the driven conveying roller 11 . The power transmission device selected in this case is a chain transmission device, and the specific implementation method is: the driving sprocket 7 is set on the driving conveying roller 10, the driven sprocket 12 is set on the driven conveying roller 11; the driving sprocket 7, the driven sprocket The sprockets 12 are connected with closed chains (not shown).

The above-mentioned toothed roller conveyors can be connected in series in sequence to extend the material conveying distance. In order to facilitate the connection, the second conveying roller is selected as the active conveying roller.

When in use, as shown in Figure 3, determine the number of required toothed roller conveyors according to the distance from the stack to the feed port 15 of the wood chipper 14 and connect the toothed roller conveyors in series, and use anchor screws to reliably connect the anchors 9 with foundation. Start the power source 1 to drive the driving conveyor roller 10 to run after being decelerated by the reducer 2, and the power is also transmitted to the driven sprocket 12 by the driving sprocket 7 arranged on the driving conveyor roller 10 to drive the driven conveyor roller 11 to run. The hobbing gear 4 on the tooth block 13 moves the log in the material channel 5 to the woodworking chipper 14 feeding by the material stack to the woodworking chipper 14 feed port 15. During the log conveying process, the smaller sundries are discharged from the production line through the gap between the conveying rollers, and the larger sundries can be manually removed.

The beneficial effects of the utility model are:

Increase the force of the conveying roller on the material during the material conveying process, reduce the hysteresis of the material relative to the conveying roller, improve the conveying efficiency, and easily remove small debris, especially suitable for feeding wood chippers materials to improve product quality.

The structure is simple and easy to use, and the conveying distance can be extended as required.
