[0042] To make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0043] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a flexible screening device for a car receiving chute, which comprises a car receiving chute 1 and a grate plate 2 arranged on the car receiving chute 1. One side of the grate plate 2 is hingedly connected to the outer wall of the upper opening of the car receiving chute 1, and the other opposite side is movably hingedly connected to the outer wall of the upper opening of the car receiving chute 1 on the opposite side. A plurality of vibration motors 3 are arranged on the upper end of the side of the grate plate 2 away from the car feeding part. In the specific arrangement, 1-2 vibration motors 3 can be arranged, and the power is selected as 1.1 kW.

[0044] A wall on the side of the car receiving chute 1 away from the car feeding side is provided with:

[0045] A mounting seat 41 is fixedly arranged on the wall of the car receiving chute 1 away from the car feeding side and above the grate plate 2;

[0046] A stroke contraction rod 42 is elastically arranged on the mounting seat 41 at the upper end and movably hingedly connected to the grate plate 2 at the lower end; and

[0047] An induction block 43 and a proximity switch 44 are arranged on the outer wall of the car receiving chute 1 and the stroke contraction rod 42 respectively. The proximity switch 44 is electrically connected to the vibration motor 3. In the embodiment, the proximity switch 44 is arranged on the wall of the car receiving chute 1, and the induction block 43 is arranged on the stroke contraction rod 42.

[0048] When the stroke contraction rod 42 is lowered to the sensing block 43 to reach the sensing range of the proximity switch 44, the vibration motor 3 is controlled to start.

[0049] Specifically, referring to Figure 2 and Figure 3 , the mounting seat 41 is provided with:

[0050] a support plate 45 horizontally fixed to the mounting seat 41, and the upper end of the stroke contraction rod 42 penetrates through the support plate 45;

[0051] a fixed block 46 fixed to the top end of the stroke contraction rod 42;

[0052] a compression spring 47 sleeved outside the stroke contraction rod 42 and located between the fixed block 46 and the support plate 45;

[0053] The compression spring 47 is configured to have a compression deformation amount that meets the required stroke of the stroke contraction rod 42 to be lowered to the sensing block 43 to reach the sensing range of the proximity switch 44 when the load on the grate plate 2 exceeds a set normal value.

[0054] Therefore, when the automobile is normally unloaded, the grate plate 2 sinks on the automobile receiving chute 1 under the action of the material gravity, specifically, the end of the grate plate 2 provided with the vibration motor 3 is turned down, which can drive the stroke contraction rod 42 to be lowered, and when the stroke contraction rod 42 is lowered, on the one hand, the compression spring 47 is compressed to generate deformation; on the other hand, the sensing block 43 on the stroke contraction rod 42 is lowered and corresponds to the proximity switch 44, the proximity switch 44 controls the vibration motor 3 to start, and when the vibration motor 3 starts, it can drive the grate plate 2 to cooperate with the material on the automobile receiving chute 1 to vibrate and sieve, which can improve the material sieving efficiency. When the material is sieved and the gravity is eliminated, the stroke contraction rod 42 is lifted under the action of the deformation force of the compression spring 47, so that the grate plate 2 is lifted and reset, the sensing block 43 on the stroke contraction rod 42 is also lifted and out of the sensing range of the proximity switch 44, and the proximity switch 44 controls the vibration motor 3 to be closed. Therefore, the automatic vibration and sieving of the grate plate 2 when receiving material and the automatic closing after stopping material can be realized, without the need for personnel on duty, and the material sieving efficiency is higher.

[0055] In addition, a plurality of fixing screws 48 for fixing on the outer side wall of the automobile receiving chute 1 are provided on the mounting seat 41, and a protective cover 49 for shielding the compression spring 47 is provided on the mounting seat 41, which is used to block the material and dust splashed during the vibration and sieving process, so as not to affect the normal work of the stroke contraction rod 42 and the compression spring 47.

[0056] At the same time, in order to avoid the influence of the sieving efficiency due to the abnormality in the sieving process without timely solution, referring to Figure 2The vibration motor 3 is electrically connected with a timer 51 for recording the continuous working time of the vibration motor 3, and the timer 51 is electrically connected with an alarm 52 through a controller, and the controller is configured to control the alarm 52 to work when the time recorded by the timer 51 exceeds the set time limit.

[0057] Therefore, when the material is wet and sticky or the large block of sundries blocks the slot of the automobile receiving chute 1 and cannot be shaken through the grate plate 2 for a long time, the alarm 52 in the post room starts to alarm when the working time of the vibration motor 3 exceeds the set time limit, prompting the post personnel to clean the blockage and pick up the sundries in time, and personnel do not need to stand on site for a long time.

[0058] Further, in order to ensure the connection stability of the grate plate 2 with the outer side wall of the automobile receiving chute 1 during the vibration screening process, referring to Figure 1 、 Figure 2 and Figure 4 , 2-4 groups of first hinged units 6 are arranged between the side of the grate plate 2 away from the vibration motor 3 and the outer side wall of the automobile receiving chute 1, 4-6 groups of second hinged units 7 are arranged between the side of the grate plate 2 close to the vibration motor 3 and the outer side wall of the automobile receiving chute 1, and the grate plate 2 is hingedly arranged on the outer side wall of the automobile receiving chute 1 through the multiple groups of first hinged units 6 and the multiple groups of second hinged units 7.

[0059] The first hinged unit 6 comprises a first hinged seat 61 and a first hinged rod 62 hingedly connected, the first hinged seat 61 is fixedly connected to the outer side wall or the steel structure of the automobile receiving chute 1, and the first hinged rod 62 is fixedly connected to the grate plate 2.

[0060] The second hinged unit 7 comprises a second hinged seat 71 and a second hinged rod 72 hingedly connected, the second hinged seat 71 is fixedly connected to the grate plate 2, and the second hinged rod 72 is hingedly connected to the lower end of the stroke contraction rod 42 at an end away from the second hinged seat 71.

[0061] Therefore, the grate plate 2 can stably vibrate and screen the material on the automobile receiving chute 1.

[0062] In addition, as some adaptive settings, the upper part of the automobile receiving chute 1 is a square warehouse, the lower part is a tapered steel structure warehouse body, the inner wall of the automobile receiving chute 1 is fully paved with wear-resistant lining plates, and a warehouse wall vibrator is arranged; the effective volume in the warehouse of the automobile receiving chute 1 is not less than 70m 3 , and the slot size of the automobile receiving chute 1 can be selected as 6m*6m, and the aperture of the grate plate 2 can be selected as 30*30cm.

[0063] The implementation principle of the automobile receiving chute flexible screening device in the embodiment of the application is as follows:

[0064] When the automobile is normally unloaded, the grate plate 2 sinks on the automobile receiving groove 1 under the action of the material gravity, specifically, one end of the grate plate 2 provided with the vibration motor 3 is turned down, which can drive the stroke contraction rod 42 to move down, when the stroke contraction rod 42 moves down, on the one hand, the compression spring 47 is compressed to produce deformation; on the other hand, the sensing block 43 on the stroke contraction rod 42 moves down and corresponds to the proximity switch 44, the proximity switch 44 controls the vibration motor 3 to start, when the vibration motor 3 starts, it can drive the grate plate 2 to cooperate with the material on the automobile receiving groove 1 to vibrate and sieve, which can improve the material screening efficiency. When the material is sieved and the gravity is eliminated, the stroke contraction rod 42 moves up under the action of the deformation force of the compression spring 47, so that the grate plate 2 moves up and resets, the sensing block 43 on the stroke contraction rod 42 also moves up and leaves the sensing range of the proximity switch 44, the proximity switch 44 controls the vibration motor 3 to close. Thus, the automatic vibration and sieve of the grate plate 2 when receiving the material and the automatic closing after stopping the material can be realized, personnel on duty is not needed, and the material screening efficiency is higher.
