Description

Technical Field

[0001] This utility model relates to the field of material crushing technology, specifically to an improved structure for the feed inlet of a crusher. Background Technology

[0002] Figure 1 and Figure 2 The image shows the original structure. Since the angle of the chute cannot be adjusted, if the material falls at a high speed, it will continuously impact one side of the crusher's crushing bin, causing the side liner to wear very easily and reducing its service life. This is obviously not in line with the design criteria. Therefore, an improved structure for the crusher's discharge port was designed to change the position where the material enters the crusher and reduce the impact of the material on the crusher's inner liner. Utility Model Content

[0003] The purpose of this invention is to provide an improved structure for the feed inlet of a crusher to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an improved structure for a crusher discharge port, comprising a crusher, a chute, and a vibrating feeder arranged in sequence, wherein the chute connects the discharge port of the vibrating feeder and the feed port of the crusher, and further comprises a support platform, wherein the chute is installed above the support platform by means of an angle adjustment device, and the pitch angle and lateral rotation angle of the chute relative to the support platform can be set by the angle adjustment device.

[0005] Preferably, the angle adjustment device includes a telescopic bar and four connecting lugs, two of which are fixed to the bottom of the chute and the other two are installed on the top of the support platform. The two ends of the telescopic bar are respectively hinged to a connecting lug on the chute and a connecting lug on the support platform, and the other two connecting lugs are hinged to each other.

[0006] Preferably, the angle adjustment device also includes multiple mounting holes provided on the top of the support platform, and the connecting lugs located on the support platform can be installed at any mounting hole position by bolts.

[0007] Preferably, the telescopic bar includes a sleeve and a rod, the rod being telescopically adjustable relative to the sleeve with the amount of telescopic extension manually adjustable.

[0008] Preferably, the chute is equipped with a removable wear-resistant liner, which is fixed to the inner wall of the chute by bolts to reduce material impact wear.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. Flexible adjustment of chute angle reduces equipment wear. The pitch and lateral angle of the chute can be precisely adjusted through the angle adjustment device, which changes the position and speed of the material entering the crusher, avoids the material from continuously hitting the same side of the crusher's crushing bin, significantly reduces the wear of the inner liner plate, and extends the service life of the equipment.

[0011] For example, by manually adjusting the extension of the telescopic bar to control the pitch angle, the material falls into the crusher at an ideal angle, achieving a buffering effect of "materials colliding with each other" rather than directly impacting the liner.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Figure 1 and Figure 2 The image shows the original structure. Because the angle of chute 3 cannot be adjusted, the material constantly impacts one side of the crusher's feed bin, causing that side to wear very easily and reducing its service life. This clearly does not meet design criteria. The improved structure is as follows:

[0020] like Figure 4 As shown, the improved structure of the crusher discharge port mainly consists of a crusher 1, a vibrating feeder 2, a chute 3, and a support platform 4. The chute 3 connects the discharge port of the vibrating feeder 2 and the feed port of the crusher 1, and the chute 3 is installed above the support platform 4 through an angle adjustment device.

[0021] The angle adjustment device has the following structure: it includes a telescopic bar 6 and four connecting lugs 5, two of which are fixed to the bottom of the chute 3, and the other two are installed on the top of the support platform 4. The telescopic bar 6 is hinged at both ends to one connecting lug 5 on the chute 3 and one connecting lug 5 on the support platform 4, respectively, and the other two connecting lugs 5 are hinged to each other. The top of the support platform 4 has multiple mounting holes 7, and the connecting lugs 5 located on the support platform 4 can be installed in any of the mounting holes 7 using bolts. The telescopic bar 6 includes a sleeve and a rod body; the rod body is telescopic relative to the sleeve, and the amount of telescopic extension is manually adjustable.

[0022] During installation, according to actual needs, the connecting lugs 5 on the support platform 4 are installed in the appropriate mounting holes 7 with bolts. This can control the lateral rotation angle of the chute 3 and prevent the material from hitting one position continuously, which would cause damage to the inner liner of the crusher 1.

[0023] Then, by manually adjusting the extension and retraction of the telescopic lever 6, the pitch angle of the chute 3 is adjusted to achieve the optimal material conveying state of the chute 3, such as... Figure 4 As shown, try to make the materials collide with each other as much as possible. This will reduce the wear of the crusher's inner liner and naturally extend its service life.

[0024] Disassembly steps: Loosen the relevant bolts, adjust the position of the connecting lug 5 or remove components such as the telescopic bar 6, and the chute 3 can be disassembled and maintained.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
