Description

Technical Field

[0001] The utility model belongs to the technical field of crushing equipment, and in particular relates to a jaw crusher with a material dividing function. Background Art

[0002] The jaw crusher with screening function is a multifunctional mechanical equipment, which is commonly found in the mining and construction industries. It combines the two functions of crushing and screening in one, and has the ability to crush materials and screen them as needed. This equipment usually consists of a pair of movable jaw plates and a screening device located below the jaw plates. The material is fed into the crushing chamber through the feed port and is crushed and broken under the action of the jaw plates. At the same time, the crushed material is screened by the screening device, and the material is divided into different particle sizes according to the set sieve hole size. This design that integrates crushing and screening functions makes the equipment highly efficient, space-saving and cost-effective, and can meet the production requirements of different particle size requirements. The jaw crusher with screening function is widely used in mining quarrying, building materials production and other fields, and is one of the important working machines in the production process.

[0003] At present, the patent with patent number 202011197920.9 discloses a jaw crusher with screening function and its use method, including a vibrating screen assembly, a temperature conduction assembly, a replacement tooth assembly, a screening frame assembly, a crusher main body assembly and a dust removal assembly; the vibrating screen assembly includes a first screen plate, a first screen plate support, a first vibration connector, a second screen plate, a dust suction port, a first hinge seat, a first connecting rod, a second hinge seat and a second screen plate support.

[0004] Although this method can achieve the work of crushing and sorting through an integrated device, on the one hand, the introduction of the vibrating screen component makes the crusher structure more complicated and the machine size larger, and the installation and debugging process is complicated and time-consuming; on the other hand, the original equipment uses two different motors to complete the crushing and sorting operations, so there is a problem of energy and cost waste. Utility Model Content

[0005] The utility model aims to provide a jaw crusher with a material dividing function, which can solve the problems that the existing device introduces a vibrating screen component, resulting in a more complicated crusher structure, an increased machine size, and a complicated and time-consuming installation and debugging process; on the other hand, it can solve the problem that the original equipment uses two different motors to complete the crushing and dividing operations, so there is a waste of energy and cost.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A jaw crusher with a material dividing function comprises: a crusher and a material dividing assembly arranged at the bottom of the crusher, wherein a driving assembly for providing power is arranged outside the crusher;

[0008] The material distribution assembly comprises: a driving disc, a material distribution eccentric shaft and a material distribution screen plate fixed on the outer periphery of the material distribution eccentric shaft; the driving disc is arranged at the shaft end of the material distribution eccentric shaft, and is used to drive the material distribution eccentric shaft to rotate;

[0009] The driving assembly comprises: a motor and a belt transmission shaft connected to the motor; the belt transmission shaft is connected to the driving disc and the flywheel of the crusher respectively through a first transmission belt and a second transmission belt;

[0010] After the motor is started, the first transmission belt and the second transmission belt drive the driving disc and the flywheel to rotate respectively, and the crusher and the material dividing assembly start to work. After the material is crushed into fine material and coarse material by the crushing chamber, it falls into the material dividing screen plate from the crusher outlet. The fine material falls to the rear side of the screen plate through the holes of the material dividing screen plate, and the coarse material falls directly to the front side of the screen plate, and the material dividing is completed.

[0011] Furthermore, it also includes a crusher bracket, which is composed of a base and a support leg. The crusher and the driving component are fixed on the surface of the base, and the material dividing component is arranged at the lower part of the base.

[0012] Furthermore, a distributor bracket is installed on the bottom surface of the base for fixing the distributor assembly.

[0013] Furthermore, the distributor bracket and the distributor screen plate are connected in a non-rigid manner.

[0014] Furthermore, the material dividing screen plate is provided with long screen holes, and the direction is the same as the falling flow direction of the material.

[0015] Furthermore, a shaft sleeve is arranged on the outer periphery of the material distribution eccentric shaft to prevent the material distribution screen plate from directly wearing the material distribution eccentric shaft.

[0016] Furthermore, the length and inclination angle of the material distribution screen plate are adjusted by adjusting the height of the shaft sleeve and the driving disc.

[0017] Furthermore, the distributor eccentric shaft and the shaft sleeve are hung on the distributor bracket through hanging bolts.

[0018] Furthermore, a spring structure is provided on the hanging bolt to cushion the impact of vibration and falling materials on the material separation screen plate.

[0019] Furthermore, the upper portion of the material dividing screen plate is connected to the base of the crusher through an iron chain.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The utility model is mainly divided into three parts: a crusher, a material distribution component and a driving component. The crusher is provided with a material distribution component at the bottom, and a driving component is provided at the outside of the crusher. The material distribution component is composed of a connecting plate, a material distribution eccentric shaft and a material distribution screen plate fixed on the outer periphery of the material distribution eccentric shaft. The driving component is composed of a motor and a belt transmission shaft connected to the motor. At the same time, the belt transmission shaft is connected to the drive plate and the flywheel of the crusher through a first transmission belt and a second transmission belt. When the motor is started, the first transmission belt and the second transmission belt drive the drive plate and the flywheel to rotate respectively, so that the crusher and the material distribution component start to work. At this time, the material is crushed into fine material and coarse material by the crushing chamber, and then falls from the crusher outlet onto the material distribution screen plate. The fine material falls to the rear side of the screen plate through the holes of the material distribution screen plate, and the coarse material falls directly to the front side of the screen plate, and the material distribution is completed. Through the above method, on the one hand, the problem that the existing device introduces a vibration screen component, which makes the crusher structure more complicated, simplifies the machine, and reduces the time-consuming process of installation and debugging; on the other hand, it solves the problem that the original equipment uses two different motors to complete the operation of crushing and material distribution, reducing the waste of energy and cost.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0025] like Figure 1 In this embodiment, it includes: a crusher 1, a material distribution component arranged at the bottom of the crusher 1, and a driving component arranged at the outside of the crusher 1;

[0026] The material distribution assembly includes: a driving disc 7, a material distribution eccentric shaft 6, and a material distribution screen plate 5 fixed on the outer periphery of the material distribution eccentric shaft 6; the driving disc 7 is arranged at the shaft end of the material distribution eccentric shaft 6, and is used to drive the material distribution eccentric shaft 6 to rotate;

[0027] It should be noted that when the material distribution assembly is working, the driving disc 7 drives the material distribution eccentric shaft 6 to rotate, and the material distribution screen plate 5 rotates coaxially therewith, and this rotation can help the material to be evenly distributed on the screen plate, and through continuous back and forth swinging, the material can pass through the screen hole more effectively. This movement helps to separate the fine particles in the material from the larger particles, and prevents the screen hole from being blocked, ensuring the continuity and efficiency of the screening process.

[0028] The driving assembly includes: a motor 8 and a belt transmission shaft 82 connected to the motor 8; the belt transmission shaft 82 is connected to the driving disc 7 and the flywheel 10 of the crusher 1 through a first transmission belt 80 and a second transmission belt 81 respectively;

[0029] It should be noted that this method can make the material dividing assembly and the crusher 1 work simultaneously after the motor is started.

[0030] In the above implementation, after the motor 8 is started, the first transmission belt 80 and the second transmission belt 81 respectively drive the drive disc 7 and the flywheel 10 to rotate, and at the same time the crusher 1 and the material dividing assembly start to work. After the material is crushed into fine material and coarse material by the crushing chamber 2, it falls from the crusher outlet 3 onto the material dividing screen plate 5. The fine material falls to the rear side of the screen plate through the holes of the material dividing screen plate 5, and the coarse material falls directly to the front side of the screen plate, and the material dividing is completed.

[0031] In this embodiment, a crusher support 9 is also included. The crusher support 9 is composed of a base and a support leg. The crusher 1 and the driving component are fixed on the surface of the base, and the material dividing component is arranged at the lower part of the base.

[0032] It should be noted that adopting this method can save space, save structural weight, and facilitate maintenance and operation.

[0033] In this embodiment, the distributor bracket 4 is installed on the bottom surface of the base, and the distributor bracket 4 is connected to the distributor screen plate 5 by a hinge, and can also be connected in the form of a slot, a slide rail or a bearing.

[0034] It should be noted that this method facilitates the relative movement between the material distributor screen plate 5 and the distributor bracket 4 while meeting the fatigue strength requirement.

[0035] In this embodiment, the material dividing screen plate 5 is provided with long screen holes, and the direction is the same as the falling flow direction of the material.

[0036] It should be noted that this method is conducive to material rolling.

[0037] In this embodiment, a shaft sleeve is provided on the outer periphery of the material distribution eccentric shaft 6 to prevent the material distribution screen plate 5 from directly wearing the material distribution eccentric shaft 6 .

[0038] It should be noted that the material distribution screen plate 5 is integrated with the shaft sleeve and is not concentric with the material distribution drive disc 7 .

[0039] In this embodiment, the length and the inclination angle of the material dividing screen plate 5 are adjusted by the height of the shaft sleeve and the driving disc 7 .

[0040] In this embodiment, the distributor eccentric shaft 6 and the shaft sleeve are hung on the distributor bracket 4 through hanging bolts.

[0041] It should be noted that the adjusting bolt can adjust the eccentric shaft of the material distribution and thus adjust the inclination angle of the material distribution screen plate 5.

[0042] In this embodiment, a spring structure is provided on the hanging bolt to buffer the impact of vibration and falling materials on the material separation screen plate 5.

[0043] In this embodiment, the upper part of the material dividing screen plate 5 is connected to the base of the crusher 1 through an iron chain.

[0044] Working principle:

[0045] (1) Adjustment of the material separator screen: The material separator eccentric shaft 6 is hung on the separator bracket 4 by a hanging bolt, and the hanging bolt is provided with a spring structure to buffer the vibration and the impact of the material falling on the material separator screen 5. The inclination angle and position of the material separator screen 5 can be changed by adjusting the bolts to meet different screening requirements.

[0046] (2) Structural support and connection: The crusher bracket 9 fixes the crusher 1 and the drive assembly to provide stable support. The material separation screen plate 5 is connected to the base of the crusher 1 through an iron chain to ensure the stability of the screen plate.

[0047] (3) Motor start: The motor 8 starts and transmits power to the drive disc 7 and the flywheel 10 of the crusher 1 through the belt drive shaft 82 through the first drive belt 80 and the second drive belt 81 respectively.

[0048] (4) Crusher operation: After the crusher 1 is started, the material is crushed in the crushing chamber 2 and divided into fine material and coarse material.

[0049] (5) Material separation: The crushed material falls from the crusher outlet 3 onto the material separation screen plate 5. Due to the reciprocating rotation of the material separation screen plate 5, the driving disk 7 drives the material separation eccentric shaft 6 and the material separation screen plate 5 to rotate coaxially. Finally, the fine material passes through the long sieve holes of the screen plate and falls to the back side of the screen plate, while the coarse material falls directly to the front side of the screen plate, and the material separation is completed.

[0050] Through this series of designs and structural arrangements, not only the crushing and grading of materials are effectively achieved, but also the space occupancy and structural weight are optimized and the maintenance operation is simplified.

[0051] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
