The first limit switch 6, the second limit switch 7 and the limit mechanism 5 are all mounted on the body 102 above the high platform 2, which facilitates maintenance and adjustment of the limit mechanism 5, wherein, referring to fig. 6 and fig. 7 in combination with fig. 4 and fig. 5, the limit mechanism 5 includes a guide body 501, a slider 502 and a driving rod 503 for driving the slider 502 to slide, the guide body 501 is mounted on the body 102 and is disposed between the first limit switch 6 and the second limit switch 7, a sliding slot (not shown in the figure) for the slider 502 to slide is disposed on the guide body 501, a first limit rod 505 and a second limit rod 506 are respectively disposed at two ends of the slider 502, a through hole 504 for the driving rod to penetrate is disposed on the slider 502, one end of the driving rod 503 of the limit mechanism 5 located at one side of the body 102 is fixedly connected to one of the two doors 103, the other end of the driving rod 503 of the limit mechanism 5 located at one side of the body 102 passes through the through hole 504 of the limit mechanism 5 located at one side of the body 102 and, one end of the driving rod 503 of the limiting mechanism 5 located at the other side of the body 102 is fixedly connected to the other door 103 of the two doors 103, and the other end of the driving rod passes through the through hole 504 of the limiting mechanism 5 located at the other side of the body 102 and extends to the upper side of the guide body 501 of the limiting mechanism 5 located at the other side of the body 102. The two ends of the sliding chute are provided with openings 508 through which the first limiting rod 505 and the second limiting rod 506 pass out of the guide body 501 to touch the first limiting switch 6 and the second limiting switch 7.
The working principle of the limiting mechanism 5 of the hopper 1 is as follows: in the process that the driving mechanism 104 drives the two doors 103 to rotate relative to the body 102 so as to enable the two doors 103 to approach each other, the driving rod 503 can drive the sliding block 502 to slide along the sliding groove in the direction of approaching the first limit switch 6, when the sliding block 502 slides to enable the first limit rod 505 to touch the first limit switch 6, the two doors 103 are closed in place, and the driving mechanism 104 stops driving; when the driving mechanism 104 drives the two doors 103 to rotate relative to the body 102 so as to move the two doors 103 away from each other, the driving rod 503 can drive the sliding block 502 to slide along the sliding groove in a direction approaching the second limit switch 7, when the sliding block 502 slides to make the second limit rod 506 touch the second limit switch 7, the two doors 103 are opened in place, and the driving mechanism 104 stops driving.
In order to ensure that the two doors 103 are tightly closed and the opening degrees of the two doors 103 can be accurately adjusted, the first limiting rod 505 and the second limiting rod 506 can be in threaded connection with the sliding block 502, and only the length of the threaded connection needs to be adjusted, so that the two doors 103 can be tightly closed and the opening degrees of the two doors 103 can be adjusted, without changing the positions of the first limiting switch 6 and the second limiting switch 7.
Specifically, when the two doors 103 cannot be closed tightly to cause the mud cake 4 to leak out and pollute the environment, the first limiting rod 505 can be screwed into the slider 502 to shorten the length of the first limiting rod 505 extending out of the slider 502 and extend the sliding distance of the slider 502 sliding to touch the first limiting switch 6, so that the driving mechanism 104 drives the two doors 103 to move from the original closed position to the direction of approaching each other continuously, thereby ensuring that the two doors 103 are closed tightly.
When the opening degree of the two doors 103 needs to be increased, the second limit rod 506 is screwed into the sliding block 502 to shorten the length of the second limit rod 506 extending out of the sliding block 502 and prolong the sliding distance of the sliding block 502 sliding to touch the second limit switch 7, so that the opening degree of the two doors 103 is increased; when the opening degree of the two doors 103 needs to be reduced, the second limiting rod 506 is screwed out of the sliding block 502, so that the length of the second limiting rod 506 extending out of the sliding block 502 is increased, the sliding distance of the sliding block 502 sliding to touch the second limiting switch 7 is shortened, and the opening degree of the two doors 103 is reduced.
As shown in fig. 5, the driving rod 503 is inclined continuously during the opening of the two doors 103, and in order to prevent the slider 502 from being separated from one end of the driving rod 503, a stopper 507 for preventing the slider 502 from being separated from the driving rod 503 may be provided at one end of the driving rod 503 above the guide body 501. It is of course also possible to reduce the slot of the chute to trap the slider 502 within the chute.
Preferably, the driving mechanism 104 includes two hydraulic cylinders, each of which is fixed on the body 102, specifically, one of the hydraulic cylinders has one end connected to the body 102 and the other end connected to one of the two doors 103, and the other hydraulic cylinder has one end connected to the body 102 and the other end connected to the other door 103 of the two doors 103. When the piston rods of the two hydraulic cylinders extend, the two doors 103 rotate towards the direction of mutual approaching and are gradually closed in place; when the piston rods of the two hydraulic cylinders retract, the two doors 103 rotate in directions away from each other and gradually open to a position.
According to the hopper 1, the limiting mechanism 5 with the guide body 501, the sliding block 502 and the driving rod 503 is arranged, so that whether the two doors 103 of the hopper 1 are opened and closed in place can be detected, meanwhile, the first limiting rod 505 and the second limiting rod 506 are in threaded connection with the sliding block 502, the two doors 103 can be closed tightly, the opening degree adjusting precision of the two doors 103 can be improved, the first limiting switch 6, the second limiting switch 7 and the limiting mechanism 5 are all arranged on the body 102 above the high platform 2, the overhauling and the adjustment of the length of the threaded connection between the first limiting rod 505 and the sliding block 502 by an operator are facilitated, and the injury of the operator caused by the climbing overhauling is avoided.
