Description

Technical Field

[0001] The utility model relates to the technical field of jaw crushers, in particular to a jaw crusher with a mobile function. Background Art

[0002] Jaw crusher is a common crushing equipment, also known as jaw crushing machinery or jaw crusher. It is a mechanical device used to crush hard materials into smaller particles. Jaw crusher is mainly composed of fixed jaw plate and movable jaw plate. When working, the movable jaw plate exerts pressure and friction on the material to crush the material into the required size.

[0003] For example, a mobile jaw crusher unit disclosed in the authorization announcement number CN205379919U has a frame, a pull rod, a main conveyor belt, a power box, a crushing motor, a jaw crusher, a feeder, a vibration motor, a tail conveyor belt and an iron remover fixedly arranged on the frame, the frame is arranged on the walking crawler, the iron remover is fixedly arranged on the main conveyor belt, the feeder is arranged on the upper side of the tail of the frame, the vibration motor is located on the lower side of the feeder, the jaw crusher is arranged in the middle of the frame, and the crushing motor is arranged on one side of the jaw crusher. After adopting the above technical scheme, the beneficial effects of the utility model are as follows: it solves the inconvenience of the fixed crushing station to determine the layout of the production line according to the terrain and geographical location, and the mobile crushing station can be moved to the place closest to the material, thereby eliminating the intermediate links from the mining of the material to the transportation away from the site and then the crushing and processing, thereby greatly reducing the transportation cost of the material.

[0004] Although the above patent solves the inconvenience of fixed crushing stations to determine the layout of the production line according to the terrain and geographical location, and the mobile crushing station can be moved to the place closest to the material, the working state and vibration amplitude of the jaw crusher will change when processing different types of materials. For example, when processing hard materials, the crusher may need to apply greater force, causing greater vibration. However, the bottom of the jaw crusher is supported and moved by a crawler vehicle. Excessive vibration will affect the wear of the connection between the crawler vehicle and the jaw crusher body, thereby affecting the service life and equipment stability. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0026] A jaw crusher with a mobile function comprises a jaw crusher body 1; a crawler vehicle 3 is fixedly installed at the bottom end of the jaw crusher body 1 through a frame 2, a screening mechanism is arranged on the inner side of the frame 2, and the screening mechanism comprises a bottom groove 6, the bottom groove 6 penetrates and is opened on one side of the middle part of the frame 2, the right side of the bottom groove 6 is located directly below the bottom end of the discharge port of the jaw crusher body 1, a screening box 7 is movably installed inside the bottom groove 6, and a second handle 8 is fixedly installed on one side of the screen box 7;

[0027] In this embodiment, the material crushed by the jaw crusher body 1 enters the screen box 7 inside the frame 2 from the discharge port. Since the vibration generated by the jaw crusher body 1 during operation will drive the screen box 7 to vibrate synchronously, the material falling into the screen box 7 will be vibrated and screened. Qualified materials fall into the receiving box 16 below for centralized collection, while unqualified materials remain on the screen box 7, thereby achieving the purpose of facilitating screening.

[0028] like Figure 2 and Figure 4 As shown, brackets 4 are symmetrically arranged on the outside of both sides of the jaw crusher body 1, a base 5 is arranged at the bottom end of the frame 2, and a shock absorbing mechanism is arranged between the four corners of the base 5 and the bracket 4. The shock absorbing mechanism includes a hydraulic rod 9, which is symmetrically arranged on both sides of the bottom end of the bracket 4. The output shaft end of the hydraulic rod 9 is provided with a support foot 10, and the four corners of the base 5 are provided with a movable groove 11 slidably connected with the support foot 10. The shock absorbing mechanism also includes a spring damper 12, which is symmetrically arranged at the inner walls on both sides of the movable groove 11, and the output shaft ends of the two spring dampers 12 are respectively arranged on both sides of the support foot 10, and the movable groove 11 is symmetrically arranged at the middle inner walls on both sides away from the spring damper 12. Rollers 14 movably connected with the guide groove 13 are arranged on both sides of the support foot 10;

[0029] In this embodiment, the vibration generated by the jaw crusher body 1 during operation is damped by the spring dampers 12 at both ends of the movable groove 11. In addition, since the crawler vehicle 3 is off the ground, no wear is caused to the connection between the jaw crusher body 1 and the crawler vehicle 3, and the noise generated by the vibration can be reduced. Moreover, when the jaw crusher body 1 is in operation, the entire device will not be displaced due to vibration.

[0030] like Figure 3 As shown, a material receiving mechanism is provided in the middle of the base 5, and the material receiving mechanism includes a placement slot 15, which is opened in the middle of the base 5, and a material receiving box 16 is movably installed inside the placement slot 15, and a first handle 17 is fixedly installed at one end of the outer side of the material receiving box 16;

[0031] In this embodiment, after the material preparation screening box 7 is screened, qualified materials fall into the material receiving box 16. When the material is crushed, the first handle 17 can be held to take the material receiving box 16 out of the placement slot 15, which is convenient for collecting when the material is crushed.

[0032] Working principle: Before the equipment crushes the material, the jaw crusher body 1 is moved to the specified position by the crawler vehicle 3 and then stopped. Then the hydraulic rod 9 at the bottom of the bracket 4 is started. The hydraulic rod 9 controls the support leg 10 to descend, and drives the base 5 at the bottom of the support leg 10 to descend synchronously until the bottom of the base 5 touches the ground and then continues to descend for a distance, so that the crawler vehicle 3 is off the ground. At this time, the material is put into the jaw crusher body 1 for crushing. The vibration generated by the jaw crusher body 1 during operation is damped by the spring dampers 12 at both ends of the movable groove 11. In addition, since the crawler vehicle 3 is off the ground, In this way, it will not cause wear to the connection between the jaw crusher body 1 and the crawler vehicle 3, and can also reduce the noise generated by vibration. When the jaw crusher body 1 is running, the entire equipment will not be displaced due to vibration; the material crushed by the jaw crusher body 1 enters the screen box 7 inside the frame 2 from the discharge port. Because the vibration generated when the jaw crusher body 1 is running will drive the screen box 7 to vibrate synchronously, the material falling into the screen box 7 will be vibrated and screened, and the qualified material falls into the receiving box 16 below for centralized collection, while the unqualified material remains on the screen box 7.

[0033] 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.
