[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Example 1

[0032] Reference Figure 1-7 The present embodiment provides a push-to-unlock mechanism, including a positioning assembly 100, including a connecting seat 101 and a fixing seat 102 arranged opposite to the connecting seat 101; a protective assembly 200, the protective assembly 200 is arranged between the connecting seat 101 and the fixing seat 102, including a first straight plate 201, a second straight plate 202 and an arc-shaped plate 203 connecting the first straight plate 201 and the second straight plate 202; a transmission assembly 300, including a tape 301, a driving wheel 302 and a driven wheel 303 are respectively provided at both ends of the tape 301, and the tape 301 is fixed by fixing frames 304 on both sides.

[0033] Specifically, the connecting seat 101 and the fixing seat 102 have the same length, are correspondingly arranged on the fixing frames 304 on both sides, and are fixed by bolts 103. The first straight plate 201 is rotatably connected to the connecting seat 101 and is detachably connected to the fixing seat 102.

[0034] Preferably, the positioning components 100 are evenly arranged on the fixing frame 304. By splicing and cooperating multiple groups of positioning components 100 and protective components 200, the belt conveyor can be completely shielded to reduce dust pollution and the influence of solar radiation on aggregates. At the same time, by connecting and cooperating the second straight plate 202 with the fixing seat 102, the second straight plate 202 can be fixed to prevent the second straight plate 202 from being blown up by the wind.

[0035] By setting up this device, not only can the unorganized dust generated near the material dropping point and the material receiving point of the belt conveyor be effectively prevented from escaping, but the protective component 200 can also be quickly disassembled and assembled, making it convenient for the staff to carry out maintenance.

[0036] Example 2

[0037] Reference Figure 2-6, which is the second embodiment of the utility model. This embodiment is based on the previous embodiment and is different from the previous embodiment in that: connecting plates 101a are provided at both ends of the connecting seat 101, and connecting holes 101b are provided on the connecting plates 101a. The connecting seat 101 is fixed by bolts 103; a plug hole 102a is provided on the fixing seat 102, and the inner wall of the plug hole 102a is symmetrically provided with latch teeth 102b, and the latch teeth 102b are provided with a third inclined surface 102b-1, and a groove 102b-2 is provided at the bottom of the latch teeth 102b. A T-shaped block 102c is provided below the latch teeth 102b, and a push block 102d is sleeved on the T-shaped block 102c. A protrusion 102d-1 is provided on the top of the push block 102d. The push block 10 2d is provided with a fourth inclined surface 102d-2, and the fixing seat 102 is also fixed by bolts 103; the first straight plate 201 is connected to the connecting seat 101, and the second straight plate 202 is connected to the fixing seat 102; the first straight plate 201 is provided with a connecting rod 201a, and the diameter of the connecting rod 201a matches the diameter of the connecting hole 101b, and the second straight plate 202 is provided with a tooth 202a, and the tooth 202a is provided with a telescopic chamber 202b, and the telescopic chamber 202b passes through the tooth 202a, and locking blocks 202c are provided at both ends of the telescopic chamber 202b, and the locking block 202c is provided with a first inclined surface 202c-1 and a second inclined surface 202c-2, and a spring 202c-3 is provided between the two locking blocks 202c.

[0038] Specifically, the width of each part of the protective component 200 is consistent with the width of the connecting seat 101, the number and position of the teeth 202a correspond to the socket 102a, and the length of the teeth 202a is consistent with the depth of the socket 102a. The first straight plate 201 and the second straight plate 202 on the protective component 200 are both made of hard materials, and the curved plate 203 is a material with a certain ductility. Therefore, the second straight plate 202 can move vertically within a certain range.

[0039] Preferably, since the force required to compress the spring 202c-3 is greater than the gravity of the push block 102d, when the locking block 202c is located below the push block 102d and pulls out the insert tooth 202a, the locking block 202c will first push the push block 102d upward until the push block 102d cannot move upward. At this time, the pulling force continues to be applied to the insert tooth 202a, and the locking block 202c will be pressed into the telescopic chamber 202b and compress the spring 202c-3.

[0040] Furthermore, the length of the T-shaped block 102c is greater than the height of the push block 102d, the first inclined surface 202c-1 has the same slope as the third inclined surface 102b-1, and the second inclined surface 202c-2 has the same slope as the fourth inclined surface 102d-2.

[0041] In this embodiment, when the protective component 200 is needed to cover the tape machine, the protective component 200 is rotated until the tooth 202a on the second straight plate 202 is inserted into the corresponding socket 102a. Since the first inclined surface 202c-1 and the third inclined surface 102b-1 have the same slope, during the insertion of the tooth 202a, the locking block 202c will contact the latch tooth 102b and be gradually pressed into the telescopic chamber 202b. When the tooth 202a continues to be inserted, the latch tooth 102b no longer contacts the locking block 202c. At this time, under the action of the restoring force of the spring 202c-3, the locking block 202c pops out again. Under the restriction of the latch tooth 102b, the tooth 202a cannot be pulled out from the socket 102a, thereby fixing the protective component 200.

[0042] When the tape machine fails and needs to check its working condition, the protective assembly 200 should be removed to facilitate observation by the staff. The removal of the protective assembly 200 only requires continuing to press the second straight plate 202, so that the locking block 202c begins to contact the push block 102d. The locking block 202c is pushed into the telescopic chamber 202b under the action of pressure. When the inserting tooth 202a continues to move to the bottom of the insertion hole 102a, the second inclined surface 202c-2 has the same slope as the fourth inclined surface 102d-2, so the locking block 202c pops out and clings to the fourth inclined surface 102d-2. Pulling the second straight plate 202 upward drives the locking block 202c to rise, and the rising locking block 202c will lift the pushing block 102d until the protrusion 103d-1 on the upper part of the pushing block 102d is embedded in the groove 102b-2, and the pushing block 102d can no longer rise. At this time, pulling out the second straight plate 202 will cause the locking block 202c to move along the fourth inclined surface 102d-2 and be continuously pressed back into the telescopic chamber 202b, thereby completing the unlocking of the protective component 200.

[0043] By setting up the protection components, not only can the aggregates transported on the belt conveyor be protected and the quality of the aggregates be guaranteed, but the design of quick disassembly and assembly of the shield can greatly shorten the maintenance time of the staff and improve work efficiency.

This embodiment is based on the previous embodiment, and is different from the previous embodiment in that: a rubber plate 301a is provided on the tape 301; the driving wheel 302 is connected to the transfer interface 302a, and the motor 302b is connected to the transfer interface 302a; the motor 302b is fixed to the side wall of the fixing frame 304; and a plurality of positioning components 100 are fixedly connected to the fixing frame 304.

[0046] Specifically, rubber plates 301a are provided at the boundaries of both sides of the tape 301. The rubber plates 301a can restrict the aggregates to prevent them from falling during transportation. Moreover, the rubber plates 301a are made of wear-resistant soft material. When the aggregates contact and rub against the rubber plates 301a, it is difficult to cause wear to the rubber plates 301a, and the service life is long.

[0047] Preferably, a plurality of transmission wheels may be provided between the driving wheel 302 and the driven wheel 303, so as to further improve the transmission efficiency of the belt conveyor, thereby shortening the transportation time and reducing the time that the aggregate is affected by solar radiation.
