Description

a coarse crusher

technical field

The utility model relates to a rough crusher.

Background technique

Before the use of traditional Chinese medicine, the Chinese medicinal materials are crushed, which is conducive to exerting the efficacy of traditional Chinese medicine to a greater extent. The traditional Chinese medicine crushing equipment uses the high-speed relative movement between the crushing teeth, and the crushed materials are crushed by the combined effects of impact, friction and material impact between the teeth. In the prior art, the top of the traditional Chinese medicine grinder is in the shape of an inverted trumpet, and a regulating piece is arranged between the feeding hopper and the crushing chamber, and the feeding speed of the medicine is adjusted through the regulating piece. During the process, it is very easy for the medicinal materials to be stuck at the bottom of the feeding hopper and cannot enter the crushing chamber. It is necessary to stop the machine and use tools to remove the stuck medicinal materials before continuing to start the machine to crush the medicinal materials. This is not only time-consuming and labor-intensive, but also damages the machine itself. Also big. In addition, during the crushing process of the pulverizer, the dust of the material will appear to varying degrees, and the dust also has different degrees of environmental pollution and health hazards to the human body. The materials to be crushed by the coarse crusher are often dry block materials, and the dust generated at this time is relatively large. Coarse shredders generally use various blades for crushing. For harder materials, the loss of blades is relatively large.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a rough crusher.

In order to achieve the above purpose, the technical solution adopted by the utility model is: it includes a crushing box, a feeding box connected to it is arranged above the crushing box, and two parallel shafts driven by a transmission system are arranged in the crushing box. The crushing shaft, the two crushing shafts rotate from top to bottom on the side close to each other. The surface of the crushing shaft is evenly equipped with multiple rows of crushing teeth. The crushing teeth on the two crushing shafts are staggered from each other and can be inserted into each other. Between the crushing teeth, a row of gear teeth is arranged for the crushing shaft above the crushing shaft. The upper feeding box is composed of a feeding hopper and a vertical feeding cylinder connected with the feeding hopper. The upper part of the vertical feeding A motor and a reducer connected to it are fixed, and the output end of the reducer is connected to the auger, and the auger is placed vertically in the vertical feeding cylinder.

Further, the retaining teeth are inclined to the inner crushing shaft, and extend into the crushing teeth of the crushing shaft.

Further, a storage hopper communicated with the feed hopper is installed above the feed hopper.

The utility model has the following beneficial effects: the utility model divides the feeding box into two parts, one of which is vertically arranged with the crushing box, and a screw auger is installed in this part, when the medicinal material enters into the vertical feeding cylinder through the feeding hopper , through the screw auger and evenly fed into the crushing box, thus avoiding the phenomenon that the medicinal materials are stuck in the hopper, because the spiral auger rotates at a uniform speed, the introduction can quantitatively crush the medicinal materials; the two crushing shafts are set mutually The crushing teeth are staggered, and each crushing tooth is inserted between the crushing teeth of the other party but does not touch, so that when the crushing shaft rolls, the material dumped from above can be evenly crushed into granules, and the blocking teeth face the inside of the crushing shaft The crushing teeth are tilted and extended into the crushing shaft. After the stopper teeth extend into the crushing teeth, the materials sticking to the crushing shaft can be scraped off, so that the materials can be crushed more evenly.

Description of drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the accompanying drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description These are only some embodiments of the utility model, and those skilled in the art can also obtain other drawings according to these drawings without any creative effort.

Fig. 1 is the structural representation of the utility model.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

As shown in Figure 1, the utility model includes a crushing box 1, the top of the crushing box 1 is provided with a feeding box 2 connected with it, and the bottom of the crushing box 1 is connected with a discharge port 11, and the crushing box 1 is provided with two transmission The system (shown in the figure) drives the rotating parallel crushing shaft 3, and the two crushing shafts 3 rotate from top to bottom on the side close to each other. This direction of rotation can transport the materials on both sides to the middle for crushing. The surface of the shaft 4 is evenly provided with multiple rows of crushing teeth 31, the crushing teeth 31 on the two crushing shafts 3 are staggered from each other, and can be inserted between the crushing teeth 31 of the other side to ensure the crushing effect. A row of retaining teeth 4 is configured for the crushing shaft 3 above, and the retaining teeth 4 are connected to the crushing box 1. Preferably, the retaining teeth 4 are inclined to the crushing shaft on the inside and extend into the crushing teeth of the crushing shaft. The retaining teeth After reaching into the crushing teeth, the materials sticking to the crushing shaft can be scraped off, so that the materials can be crushed more evenly.

The feeding box 2 is composed of a feed hopper 5 and a vertical feed cylinder 6 connected to the feed hopper 5. The upper part of the vertical feed cylinder 6 is fixed with a motor 7 and a reducer 8 connected thereto. The auger 9 can be controlled by the reducer. The speed of rotation, the motor 7 and the reducer 8 are fixed on the motor support, and the motor support is installed above the vertical feeding cylinder 6. In order to fix the motor and reducer on the vertical feeding cylinder, prevent the motor and reducer from being misaligned during work, and affect the work between the two gears, the motor bracket is set to fix the motor and reducer, and reduce the machine. The impact of the vibration on the two. The output end of the speed reducer is connected with the auger 9, and the auger is vertically placed in the vertical barrel. Divide the feeding box into two parts, one part is set vertically with the crushing box, and this part is equipped with an auger, when the medicinal material enters the vertical feeding cylinder through the feeding hopper, it is evenly sent to the crushing machine through the auger In this way, the phenomenon that the medicinal materials are stuck in the hopper is avoided. Since the auger rotates at a constant speed, the introduction can crush the medicinal materials quantitatively.

Since it is impossible for workers to stand beside the feed hopper and put in the medicinal materials all the time, if the storage hopper is installed, more medicinal materials can be put in at one time, and no one can be on duty for a short time. A storage hopper 10 connected to it is installed above the feed hopper. , which can improve work efficiency.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in the Within the protection scope of the present utility model.
