[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0034] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0036] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] This embodiment provides a crusher such as Figure 1-Figure 3As shown, the crusher includes a body 10 and a feed inlet adjustment device, the feed inlet adjustment device is arranged at the feed inlet of the body 10, and the body 10 is provided with a feed inlet and a material cavity that are interconnected. The material can be put into the material cavity through the feed inlet. However, the feed inlet adjustment device in the prior art cannot effectively adjust the opening of the feed inlet. Therefore, a feed inlet adjustment device is provided in this embodiment to make it more convenient to adjust the opening of the feed inlet.

[0038] like Figure 1-Figure 4 As shown, the feed port adjustment device includes an adjustment plate 20, an opening assembly 30 and a driving member 40. One side of the adjustment plate 20 is pivotally connected to the machine body 10; the opening assembly 30 is connected to the other side of the adjustment plate 20, and the opening assembly 30 can block the feed port; the opening assembly 30 can be bent into the material cavity under the action of an external force so that the material can enter the machine body 10; the driving member 40 is arranged on the machine body 10, and the driving member 40 can drive the adjustment plate 20 to rotate around the pivot position. After the adjustment plate 20 drives the opening assembly 30 to rotate, the opening assembly 30 droops in the vertical direction to increase the opening of the feed port.

[0039] In this structure, when a smaller material needs to be put in, the opening component 30 is directly pushed toward the inside of the material chamber, and the opening component 30 can bend inward, so that the material can enter the material chamber; when the material is larger, the driving member 40 is started, and the driving member 40 can drive the adjustment plate 20 to rotate upward around its pivot connection with the body 10. At this time, the opening component 30 will also be lifted up and naturally droop in the vertical direction, thereby increasing the opening of the feed port. At this time, larger materials can be put in. The operation is simple and convenient, and it is easy to use, which solves the problem of inconvenient adjustment of the feed port opening.

[0040] It should be noted here that, in this embodiment, Figure 1 As shown, a rotating shaft 11 is provided at the top of the machine body 10 along the width direction, and the adjusting plate 20 is pivotally connected to the machine body 10 through the rotating shaft 11, so that the adjusting plate 20 can rotate upward around the rotating shaft 11. In other embodiments, the adjusting plate 20 and the machine body 10 can also be connected by bending through a hinge, as long as it can ensure that the adjusting plate 20 can rotate or bend upward, and no other limitation is made in this example.

[0041] In addition, in this embodiment, the driving member 40 is a hydraulic rod, which has a simple structure, low price, and is easy to install. Figure 1-Figure 3As shown, the driving member 40 is arranged outside the machine body 10, and the output end of the driving member 40 is connected to the bottom end of the adjustment plate 20. When the opening of the feed port needs to be adjusted, the output end of the driving member 40 extends out, and then the adjustment plate 20 is lifted up, so that it can rotate upward around the rotating shaft 11, thereby increasing the opening of the feed port. At the same time, the driving member 40 is arranged outside the machine body 10, which can avoid the material splashing when the material is crushed in the material cavity and damaging the driving member 40. In addition, the machine body 10 is provided with driving members 40 on both sides along its width direction. This structure can ensure that both sides of the adjustment plate 20 can be evenly stressed, thereby ensuring a good adjustment effect.

[0042] like Figure 1-Figure 3 As shown, the opening assembly 30 includes a blocking plate 31, which is made of a flexible material. In this structure, the setting of the blocking plate 31 can prevent material debris from splashing out of the feed port during the crushing process of the crusher, thereby ensuring the safety of the work, and the blocking plate 31 is made of a flexible material and can droop naturally without external force, thereby ensuring that the blocking plate 31 will not hinder the feeding during the upward rotation of the adjustment plate 20.

[0043] In addition, the opening component 30 also includes a flexible net 32, and the blocking plate 31 is arranged on the side of the flexible net 32 ​​away from the material cavity. This structure can ensure that the material splashing in the material cavity first impacts the flexible net 32, thereby avoiding the situation where the material directly hits the blocking plate 31, thereby extending the service life of the blocking plate 31. In addition, even if there are small splashes passing through the flexible net 32, the blocking plate 31 will block them in the material cavity to avoid splashing out and causing safety hazards, thereby ensuring safety in use.

[0044] In order to further reduce the impact of the heavy material on the blocking plate 31, a reserved gap is set between the blocking plate 31 and the flexible net 32. By setting the reserved gap, it is ensured that the heavy material can only impact the flexible net 32 ​​during the splashing process, and will not contact the blocking plate 31, thereby further improving the service life of the blocking plate 31. It should be noted here that there are multiple blocking plates 31. Since the material splashes and dusts are serious in the process of crushing materials, the multi-layer blocking plates 31 are set to solve the splashing and dusting of materials. At the same time, when the innermost blocking plate 31 is damaged, the multiple blocking plates 31 on the outside can also play a role in blocking dust. In addition, multiple blocking plates 31 are set, and multiple blocking plates 31 are not combined into a large plate, so as to avoid setting multiple blocking plates 31 into a large plate, which increases rigidity invisibly, resulting in the inability to sag naturally, thereby reducing the blocking effect. It should be noted here that the specific number of blocking plates 31 is not limited in this embodiment, and it is sufficient to ensure that the entire feed port can be sealed according to actual needs.

[0045] In addition, the side of the blocking plate 31 away from the adjustment plate 20 is located inside the feed port. This structure can ensure that the entire blocking plate 31 can be placed inside the material cavity during the upward rotation of the adjustment plate 20, avoiding the problem that the end of the blocking plate 31 away from the adjustment plate 20 is stuck outside the feed port, resulting in failure to load materials.

[0046] It should be noted here that, in this embodiment, the blocking plate 31 is made of rubber material, and the flexible net 32 ​​is an iron chain net woven from iron chains. Silicone has good flexibility, is easy to produce and manufacture, and has a low price. The iron chain net is more impact-resistant and has a longer service life than nets woven from other materials. In other embodiments, the blocking plate 31 can also be made of materials such as silicone, and the flexible net 32 ​​can also be made of other metals instead of iron chains, as long as the above-mentioned technical effects can be produced, and no other limitations are made in this example.

[0047] It is worth noting that in other embodiments, the opening component 30 may also be made of a rigid material, but it is necessary to ensure that the opening component 30 is pivotally connected to the adjustment plate 20, that is, the opening component 30 can rotate around the connection position between the opening component 30 and the adjustment plate 20. This structure enables the opening component 30 to be lifted by the adjustment plate 20 when the adjustment plate 20 rotates upward around the rotation axis 11, and because the opening component 30 is subject to its own gravity (the opposite direction of gravity always points vertically downward), the end of the opening component 30 that is not connected to the adjustment plate 20 can also droop naturally, thereby producing the same technical effect as the blocking plate 31 and the flexible net 32 ​​made of flexible materials.

[0048] Finally, the use process of the feed inlet adjustment device and the crusher in this embodiment is described in conjunction with the accompanying drawings:

[0049] First, when the material is in good condition (small volume), it is only necessary to push the blocking plate 31 into the material cavity and put the material in;

[0050] Secondly, when the material is in a bad state (materials of different sizes and strange shapes), the driving member 40 drives the adjusting plate 20 to rotate upward around the rotating shaft 11, and the opening assembly 30 moves upward together. Since the blocking plate 31 and the flexible net 32 ​​are both flexible, they will naturally droop (such as Figure 4 As shown), the opening of the feed port increases and you can continue to feed the material.

[0051] Finally, turn on the crusher to crush the materials.

[0052] In summary, the use of the feed port adjustment device and the crusher in this embodiment can not only quickly adjust the opening of the feed port, but also improve work efficiency.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
