Technical Field

[0001] This utility model belongs to the technical field of bipolar pulverizers, and in particular relates to a bipolar pulverizer that is easy to feed materials. Background Technology

[0002] The dual-stage crusher is a high-efficiency crushing equipment, mainly used for secondary continuous crushing of various materials with high or relatively hard hardness to achieve ideal fine crushing effect. It is especially suitable for fine crushing of medium-hard or brittle materials.

[0003] Chinese utility model patent CN209791732U discloses a bipolar pulverizer, which features high material flow rate, prevents adhesion and clogging, and achieves rapid pulverization. However, this device requires a large number of motors, resulting in inefficient energy utilization. Furthermore, it is inconvenient to orderly discharge the crushed material and lacks a screening function, making it difficult to screen for insufficiently crushed material. Therefore, there is an urgent need to improve existing bipolar pulverizers and provide a bipolar pulverizer with screening capabilities and easy material discharge. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a reasonably designed, simple, energy-efficient, and easy-to-feed bipolar pulverizer with screening function, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-stage crusher with easy material feeding includes a machine body. A motor is fixedly installed on the front outer wall of the machine body. A first crushing hammer roller and a second crushing hammer roller are installed on the inner bearing of the machine body. The front end of the second crushing hammer roller is fixedly connected to the output end of the motor. A discharge chamber is opened inside the bottom end of the machine body. An auger roller is installed in the discharge chamber and connected to the machine body bearing. A drive assembly is installed at the rear end of the auger roller. A discharge screening assembly is fixedly installed on the front outer wall of the bottom of the machine body. A feeding port is opened inside the top end of the machine body. Two splash guards are fixedly fixed on the left and right inner walls of the feeding port in a staggered manner.

[0007] Preferably, the first breaker roller, the second breaker roller, and the auger roller are linked together by a drive assembly.

[0008] Preferably, the drive assembly includes a first pulley, a second pulley, a first belt, and a second belt. There are two first pulleys, which are respectively fixedly installed at the rear ends of the first breaker roller and the second breaker roller. The second pulley is fixedly installed at the rear end of the auger roller. The two ends of the first belt are respectively sleeved on the outside of the two first pulleys, and the two ends of the second belt are respectively sleeved on the outside of the lower first pulley and the second pulley.

[0009] Preferably, the diameter of the first pulley is half the diameter of the second pulley, and the two first pulleys and the second pulley are linked together by a first belt and a second belt.

[0010] Preferably, the discharge screening component includes a first guide frame, a screen plate, and a second guide frame. The first guide frame is fixedly installed on the outer wall of the bottom front end of the machine body and located outside the outlet of the discharge chamber. A screen plate is embedded and fixed inside the bottom end of the first guide frame, and a second guide frame is fixedly connected directly below the first guide frame.

[0011] Preferably, both the first and second guide frames are designed to be inclined, and the screen plate is located above the second guide frame and the two have the same width.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, after crushing, the device uses a rotating auger roller to push the crushed material along the discharge chamber to the discharge screening component, which can achieve orderly discharge and anti-blocking effects, thus achieving easy material discharge. Moreover, when the starting motor controls the second crushing hammer roller and the first pulley fixed at its rear end to rotate, the first belt and the second belt can be used to control the synchronous rotation of the first crushing hammer roller and the auger roller. The synchronous operation of multiple rollers can be achieved by a single motor, making the structural design more reasonable and the energy utilization more efficient.

[0014] This invention utilizes a screen plate inside the first guide frame, which allows fully crushed materials to fall into the second guide frame and roll to the right along the inclined second guide frame for discharge. Meanwhile, a small amount of insufficiently crushed material can roll forward along the inclined first guide frame for discharge, thus facilitating screening during discharge.

[0022] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0023] like Figure 1-4 As shown in the figure, the present invention provides an easy-to-discharge dual-stage crusher, which includes a machine body 1. A motor 2 is fixedly installed on the front outer wall of the machine body 1. A first crushing hammer roller 3 and a second crushing hammer roller 4 are installed on the inner bearing of the machine body 1. The front end of the second crushing hammer roller 4 is fixedly connected to the output end of the motor 2. A discharge chamber 5 is opened inside the bottom end of the machine body 1. An auger roller 6 is installed in the discharge chamber 5. The auger roller 6 is connected to the bearing of the machine body 1. A drive assembly 7 is installed at the rear end of the auger roller 6. A discharge screening assembly 8 is fixedly installed on the front outer wall of the bottom of the machine body 1. A feeding port 9 is opened inside the top end of the machine body 1. Two anti-splash plates 10 are fixedly fixed on the left and right inner walls of the feeding port 9 in a staggered manner.

[0024] As a preferred embodiment, based on the above structure, the first breaker roller 3, the second breaker roller 4, and the auger roller 6 are further linked together by the drive assembly 7.

[0025] In this embodiment, the drive component 7 facilitates the coordinated control of the first breaker roller 3, the second breaker roller 4, and the auger roller 6, resulting in more efficient and rational energy utilization.

[0026] In a preferred embodiment, based on the above structure, the drive assembly 7 further includes a first pulley 71, a second pulley 72, a first belt 73, and a second belt 74. There are two first pulleys 71, which are respectively fixedly installed at the rear ends of the first breaker roller 3 and the second breaker roller 4. The second pulley 72 is fixedly installed at the rear end of the auger roller 6. The two ends of the first belt 73 are respectively sleeved on the outside of the two first pulleys 71, and the two ends of the second belt 74 are respectively sleeved on the outside of the lower first pulley 71 and the second pulley 72.

[0027] As a preferred embodiment, based on the above structure, the diameter of the first pulley 71 is half the diameter of the second pulley 72, and the two first pulleys 71 and the second pulley 72 are linked together by the first belt 73 and the second belt 74.

[0028] In this embodiment, when the start motor 2 controls the second breaker roller 4 and the first pulley 71 behind it to rotate, the first belt 73 and the second belt 74 are used to facilitate the synchronous rotation of the first breaker roller 3 and the auger roller 6.

[0029] As a preferred embodiment, based on the above structure, the discharge screening component 8 further includes a first guide frame 81, a screen plate 82, and a second guide frame 83. The first guide frame 81 is fixedly installed on the outer wall of the bottom front end of the machine body 1 and located outside the outlet of the discharge chamber 5. The screen plate 82 is embedded and fixed inside the bottom end of the first guide frame 81, and the second guide frame 83 is fixedly connected directly below the first guide frame 81.

[0030] As a preferred embodiment, based on the above structure, both the first guide frame 81 and the second guide frame 83 are designed to be inclined, and the screen plate 82 is located above the second guide frame 83 and the two have the same width.

[0031] In this embodiment, the screen plate 82 is used to facilitate the screening of insufficiently crushed materials. Sufficiently crushed materials can be discharged by rolling to the right along the second guide frame 83, while insufficiently crushed materials can be discharged by rolling forward along the inclined first guide frame 81, which facilitates screening at the same time as discharge.

[0032] The working principle of this utility model is as follows:

[0033] In use, the material to be crushed is first added into the machine body 1 through the feeding port 9. The motor 2 is started to control the rotation of the second crushing hammer roller 4 and the first pulley 71 fixed at its rear end. Under the action of the first belt 73 and the second belt 74, it is easy to control the first crushing hammer roller 3 and the auger roller 6 to rotate synchronously, so as to realize the crushing process of the material. In this device, multiple rollers can be operated synchronously by a single motor 2, the structural design is more reasonable, and the energy utilization is more efficient.

[0034] The crushed material can fall into the discharge chamber 5 and be pushed forward by the rotating auger roller 6. Since the diameter of the second pulley 72 is larger than the diameter of the first pulley 71, the rotation speed of the auger roller 6 is less than that of the first crusher roller 3 and the second crusher roller 4, which can achieve the effect of orderly discharge and anti-blocking, and achieve the purpose of easy material discharge.

[0035] After the crushed material is pushed into the first guide frame 81, the screen plate 82 makes it easy for the fully crushed material to fall into the inclined second guide frame 83 and roll to the right to be discharged, while the insufficiently crushed material can roll forward along the inclined first guide frame 81 to be discharged, thus making it easy to achieve the effect of screening at the same time as discharging.

[0036] It should be noted that the first breaker roller 3 and the second breaker roller 4 in this device, as well as the specific auxiliary crushing structure inside the machine body 1, are all existing mature technologies. This is not an innovative improvement direction of this case, but a direct reference to existing technology products, so it will not be described in detail.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
