If the term "first" or "second" is used in a description, it is only used to distinguish technical features and should not be understood to indicate or imply relative importance, implicitly specify the number of the indicated technical features, or implicitly specify the order of the indicated technical features.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] The plastic crusher has a knife holder in the crushing box, a moving blade on the knife holder shaft, and a fixed blade on the crushing box. The moving blade rotates relative to the fixed blade to crush large plastic raw materials into small granular crushed materials. The size of the crushed particles is determined by the size of the screen aperture at the bottom of the crushing box. The crushed particles fall through the screen aperture, and the crushing process is completed.

[0033] The particles crushed by conventional plastic crushers are designed to fall directly to the ground in some designs and then be collected and bagged manually. In other designs, the particles fall into the collection box under the screen, and the material is collected and bagged manually after it is full. These designs waste manpower and have low efficiency. At the same time, since there is no sealed structure under the screen, it is easy to cause dust to fly, affecting the working environment of the operator.

[0034] In response to the above technical problems, an embodiment of the present utility model proposes a plastic crusher with a crusher conveying device. By externally installing a conveying device on the plastic crusher, the crushed material is transported to a location convenient for loading or bagging. The transportation process is closed and fully automatic, reducing dust and improving efficiency.

[0035] A plastic crusher with a crushed material conveying device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0036] Reference Figure 1 As shown, in an embodiment of the present invention, a plastic pulverizer with a crushed material conveying device includes a crushing chamber 1, a collection box 5, a feed pipe 7, a driver 18, a collection bucket 11, and a filter. The collection box 5 is disposed at the discharge port at the bottom of the crushing chamber 1, the feed pipe 7 is connected to the collection box 5, the driver 18 is disposed on the feed pipe 7, the collection bucket 11 is connected to the end of the feed pipe 7 away from the collection box 5 and is tangential to the feed pipe 7, the filter is disposed at a first opening at the top of the collection bucket 11, and a second opening at the bottom of the collection bucket 11 is used to discharge the crushed material.

[0037] Reference Figure 1 and Figure 3 As shown, in this embodiment of the present invention, a crushing chamber 1 is equipped with a movable blade 2 and a fixed blade 3. The movable blade 2 can rotate relative to the fixed blade 3 to cut and crush the plastic raw material. A screen 4 is provided at the bottom of the crushing chamber 1 to filter out small particles and screen out large particles. Guide grooves are provided at the discharge port at the bottom of the crushing chamber 1. The guide grooves are located on both sides of the discharge port. A collection box 5 is removably mounted in the guide grooves via adjustment bolts. After loosening the adjustment bolts, the collection box 5 can be withdrawn along the guide grooves.

[0038] It should be noted that in the embodiment of the present invention, the aggregate box 5 has a conical structure, and the cross-sectional area of ​​the aggregate box 5 gradually decreases along the direction of movement of the crushed material from the discharge port of the pulverizing chamber 1. The crushed material gradually gathers as it moves to the feed pipe 7, achieving the effect of aggregate collection. A viewing window 6 for observing the crushed material inside is provided on the side of the aggregate box 5. When the crushed material inside the aggregate box 5 is observed to be full through the viewing window 6, the driver 18 can be activated to extract the crushed material. This eliminates the need to continuously operate the driver 18, saving energy. The driver 18 is configured as a blower.

[0039] It should be noted that in the embodiment of the present invention, an air inlet is provided at one end of the feed pipe 7 near the collecting box 5, and a filter hole 8 is provided at the air inlet for filtering external impurities, such as fixed particles, dust, etc. A cover is provided at the air inlet, and the filter hole 8 is provided on the cover. The split design facilitates later maintenance.

[0040] It should be noted that in the embodiment of the present utility model, the aggregate bucket 11 is provided with an adjustable height bracket, which includes an upper bracket 9 and a lower bracket 10. The lower bracket 10 is sleeved on the upper bracket 9. Both the upper bracket 9 and the lower bracket 10 are provided with fixing holes for installing fixing bolts. Multiple fixing holes are arranged along the length direction of the upper bracket 9 and the lower bracket 10. When the height of the aggregate bucket 11 needs to be adjusted, the fixing bolts are loosened, the upper bracket 9 is stretched or contracted, and the fixing bolts are retightened after the adjustment is completed.

[0041] It should be noted that, in the embodiment of the present utility model, the aggregate barrel 11 has a first part 12 and a second part 13. The first part 12 is configured as a hollow cylinder connected at both ends, and the side wall is provided with a tangential feed port, which is used to install the feed pipe 7. One end of the hollow cylinder has a first opening, and the other end is connected to the second part 13. The second part 13 is configured as a hollow cone connected at both ends. The upper base area of ​​the hollow cone is larger than the lower base area. The upper bottom surface of the hollow cone is connected to the hollow cylinder, and the lower bottom surface of the hollow cone has a second opening.

[0042] It is understandable that the crushed material will fall from the first part 12 to the second part 13 under the action of gravity. Since the second part 13 is a gradually shrinking frustum structure, the crushed material will gather after entering the second part 13, which is convenient for discharge and avoids dust.

[0043] In addition, the collecting barrel 11 is provided with a discharge pipe 14 at the second opening thereof, which can adjust the discharge direction.

[0044] It should be noted that in this embodiment of the present invention, the filter comprises an outlet pipe 15 and a breathable bag 16. The inlet end of the outlet pipe 15 is connected to the first opening, and the breathable bag 16 is located at the outlet end of the outlet pipe 15. The filter also comprises a breathable tube bundle 17, which is located at the outlet end of the outlet pipe 15 and the breathable bag 16 is sleeved therein. The tube bundle 17 provides support for the breathable bag 16. The breathable bag 16 filters the exhausted air, preventing the pulverized material entrained in the air from being discharged into the atmosphere, thus providing a better working environment.

[0045] Reference Figure 2 As shown, in the embodiment of the present utility model, the working principle of the plastic crusher with crushed material conveying device is as follows:

[0046] When the crushing chamber 1 is working, the plastic raw material is crushed into small-sized crushed materials, which fall into the collecting box 5. The driver 18 is started, and flowing air is generated under the action of negative pressure. The flowing air drives the crushed materials to move in the conveying pipe 7. After the crushed materials enter the collecting barrel 11, they produce spiral motion and gather at the central axis of the collecting barrel 11. The gathered crushed materials are discharged from the second opening due to gravity, and the flowing air spirally rises and is discharged from the first outlet. The solid impurities mixed in the flowing air are filtered by the filter.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
