Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, and more specifically, to a bamboo product crushing device. Background Technology

[0002] A bamboo product crushing device is a mechanical device used to crush bamboo materials, such as bamboo logs and bamboo product scraps. The production, processing, and use of bamboo products generate a large amount of waste, such as fragments and pieces of bamboo cut from bamboo furniture production, and leftover materials from bamboo handicrafts. Crushing these bamboo products allows them to be transformed back into valuable raw materials, preventing them from being discarded as waste and greatly reducing resource waste.

[0003] Existing bamboo product crushing and processing equipment mostly uses crushing mechanisms to directly crush bamboo, resulting in a large amount of bamboo fiber. When producing bamboo charcoal and other products, this fiber affects the quality of the finished product, requiring secondary processing. This secondary processing significantly increases production costs and reduces production efficiency. Therefore, we propose a bamboo product crushing device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a bamboo product crushing device to solve the technical problem that the current crushing device produces a large amount of bamboo fiber when crushing bamboo pieces, which affects the crushing effect and requires secondary processing.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a bamboo product crushing device, including an outer cylinder, an inner rotating cylinder, and a storage box. The front end of the outer cylinder is provided with a side cover, and a drive box is provided outside the side cover. A feed pipe is installed through one side of the outer cylinder, and a discharge pipe is installed through the lower rear end of the outer cylinder. An assembly cover is provided at the rear end of the outer cylinder. The storage box is installed at the bottom inner end of the outer cylinder. The inner rotating cylinder is rotatably installed in the middle of the inner part of the outer cylinder through a bearing component. A shaft interface is opened at the front end of the outer cylinder, and the shaft interface is connected to the output shaft of the drive box. Crushing rods are arranged in a ring array on the outer side of the inner rotating cylinder. An assembly cylinder is installed in the middle of the inner side of the assembly cover, and a crushing sleeve is fitted over the assembly cylinder.

[0006] In use, this invention is powered by an external power source. The operator starts the device via an external control device, introducing bamboo strips through the feed pipe. Then, the motor inside the drive box is started, driving the inner drum to rotate. During the rotation of the inner drum, the outer crushing rod crushes the bamboo strips, forming small bamboo strips and bamboo fibers. These small bamboo strips and bamboo fibers then fall into the inner drum through the feed inlet, where they are further ground into powder by the inner grinding blocks and crushing sleeve. The bamboo powder is then sieved through a filter screen into the storage box and discharged through the discharge pipe. Through the above structural design, the bamboo strips are first crushed by the crushing rod after being introduced. The bamboo powder is then produced by grinding bamboo through the inner grinding block and crushing sleeve, eliminating bamboo fibers and facilitating subsequent production. This eliminates the need for secondary processing, reducing costs and increasing production efficiency. The upper side of the storage box has an arc-shaped design, leaving a gap between it and the inner rotating drum. When crushed bamboo material is easily accumulated in the gap, it will affect the normal discharge of bamboo powder from the filter screen. The crushing rod lifts the material accumulated on the upper side, allowing the bamboo material to enter the inner rotating drum through the feed port for easy grinding. The gap between the storage box and the inner rotating drum allows for material storage, and the crushing rod lifts the material for continuous processing, avoiding internal material accumulation.

[0007] Preferably, the storage box has an arc-shaped design and is adapted to the outer cylinder. A filter screen is provided at the upper opening of the storage box, and the distance between the filter screen and the inner rotating cylinder is adapted to the crushing rod.

[0008] Preferably, the storage box has notches on the upper sides of both ends, and the notches correspond to the feed pipes, and the discharge pipes are connected to the bottom of the storage box.

[0009] Preferably, the outer annular array of the inner rotating cylinder has a material inlet, and the inner annular array of the inner rotating cylinder has inner grinding blocks distributed in a staggered manner with respect to the material inlet. The inner grinding blocks are fixed to the inner rotating cylinder by fixing screws.

[0010] Preferably, the outer side of the assembly cylinder is provided with a limiting strip, the inner side of the crushing sleeve is provided with a limiting port, and the limiting port is connected to the limiting strip. The assembly cylinder is inserted into the inner side of the inner rotating cylinder, and the crushing sleeve is in close contact with the inner grinding block.

[0011] Preferably, both ends of the storage box are provided with inclined downward pressing surfaces, and the inclined surfaces are adapted to the rotation direction of the crushing rod, and the width of the storage box is adapted to the inner rotating cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model designs an inner rotating drum to introduce bamboo strips through the feed pipe. Then, the motor in the drive box is started to drive the inner rotating drum to rotate. During the rotation of the inner rotating drum, the outer crushing rod crushes the bamboo strips, forming small bamboo strips and bamboo fibers. The small bamboo strips and bamboo fibers then fall into the inner side of the inner rotating drum through the feed port. The inner grinding block and crushing sleeve then grind the small bamboo strips and bamboo fibers into powder. The bamboo powder is screened into the storage box through the filter screen and then discharged through the discharge pipe. Through the above structural design, the bamboo strips are first crushed by the crushing rod after being introduced, and then ground into powder by the inner grinding block and crushing sleeve to complete the production of bamboo powder. This eliminates bamboo fibers, facilitates subsequent production, reduces costs without secondary processing, and improves production efficiency.

[0014] 2. This utility model also features a storage box with an arc-shaped upper side, creating a gap between the storage box and the inner rotating drum. This allows crushed bamboo material to easily accumulate in the gap, which can hinder the normal discharge of bamboo powder from the filter screen. The crushing rod lifts the material accumulated on the upper side, allowing it to enter the inner rotating drum through the feed inlet for easy grinding. The gap between the storage box and the inner rotating drum facilitates continuous processing, preventing internal material accumulation. Attached Figure Description
