Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of belt conveyor equipment, in particular to a belt conveyor sand and gravel guiding and sorting gate. Background Art
[0002] As we all know, in tunnel excavation, a belt conveyor is needed to guide the sand and gravel excavated from the tunnel to the outside. In order to further recover the sand and gravel, it is usually necessary to sort the sand and gravel, especially the separation between stones and mud. Therefore, a device for sand and gravel sorting is set at the discharge gate of the belt conveyor to achieve preliminary sorting of sand and gravel.
[0003] At present, the existing sorting gates generally only set up a screening plate, and then rely on the free fall of sand and gravel to separate the sand and gravel. However, relying on the free fall of sand and gravel alone will cause insufficient screening to a large extent. Although the screening effect can be improved by arranging the screening plate at an angle, the screening is still insufficient. In order to improve the screening effect, some motors and deflection components are usually installed to provide vibration or deflection force. However, this design often requires power supply and connection design between the deflection component and the motor shaft. Because the belt conveyor itself is very compact, this design often increases the difficulty of design, and even requires the overall volume of the belt conveyor to be enlarged to meet the design requirements. It is obviously not an ideal solution for the structural design of the belt conveyor. Utility Model Content
[0004] In view of the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a belt conveyor sand and gravel guiding and sorting gate.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A belt conveyor sand and gravel guiding and sorting gate, comprising a gate channel, a screen plate and a feed conveyor belt for inputting sand and gravel, the upper port of the gate channel is connected to the feed conveyor belt, so that the sand and gravel transmitted by the feed conveyor belt is discharged into the gate channel, a support seat is arranged in the gate channel, a first base plate is connected to the top of the support seat through a first spring, one end of the screen plate is hingedly connected to the first base plate, the other end of the screen plate is hingedly connected to the second base plate, and the screen plate is inclined in the gate channel, the back of the second base plate is connected to the inner wall of the gate channel through a second spring, the screen plate is provided with screen holes for screening sand and gravel, the screen plate separates the inner cavity of the gate channel into a stone cavity and a sand cavity, and the sand and gravel input by the feed conveyor belt all fall on the screen plate.
[0007] Preferably, at least one limiting rope is connected to the top of the second substrate, and the other end of the limiting rope is connected to the inner wall of the gate channel. The limiting rope has a reserved length sufficient for the normal deflection of the second substrate, so that the second substrate can swing within a certain range.
[0008] Preferably, at least one round rod is provided between the sieve holes of the sieve plate, and the round rod is transversely arranged on the sieve plate.
[0009] Preferably, the diameter of the round rod is 2-3 cm.
[0010] Preferably, the support seat or the first substrate is provided with limiting columns whose number corresponds to the first springs, and the first springs are sleeved on the limiting columns.
[0011] Due to the adoption of the above scheme, the utility model relies on the feed conveyor belt to transport sand and gravel into the gate channel, allowing the discharged sand and gravel to hit the screen plate, and the screen plate is arranged at an angle, and a first spring in the vertical direction and another second spring in the horizontal direction are provided at both ends of the screen plate. Under the continuous impact of sand and gravel, corresponding shaking will be generated, causing the screen plate to swing up and down and left and right, thereby further enhancing the effect of sand and gravel screening. The overall function of preliminary screening of sand and gravel can be well completed without the need to install external kinetic energy such as motors. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figures 1 to 4 As shown, a belt conveyor gravel guiding and sorting gate provided in this embodiment includes a gate channel 1, a screen plate 2 and a feed conveyor belt 3 for inputting gravel 100. The upper end of the gate channel 1 is connected to the feed conveyor belt 3, so that the gravel 100 transmitted by the feed conveyor belt 3 is discharged into the gate channel. A support seat 4 is arranged in the gate channel 1. The upper part of the support seat 4 is connected to a first base plate 6 through a first spring 5. One end of the screen plate 2 is hingedly connected to the first base plate 6. The sieve plate 2 is hingedly connected to a second base plate 7 at the other end thereof, and the sieve plate 2 is inclined in the gate channel 1, and the angle is set to be 45° to 60°. The back of the second base plate 7 is connected to the inner wall of the gate channel 1 through a second spring 8. The sieve plate 2 is provided with sieve holes 9 for screening sand and gravel. The sieve plate 2 divides the inner cavity of the gate channel 1 into a stone cavity 10 and a sand cavity 11, and the sand and gravel 100 input by the feed conveyor belt 3 all fall on the sieve plate 2.
[0020] This embodiment mainly relies on the feed conveyor belt 3 to transport the sand and gravel 100 into the gate channel 1, so that the discharged sand and gravel 100 hits the screen plate 2, and the screen plate 2 is arranged inclined, and a first spring 5 in the vertical direction and another second spring 8 in the horizontal direction are provided at both ends of the screen plate 2. Under the continuous impact of the sand and gravel 100, corresponding shaking will be generated, so that the screen plate 2 will swing up and down and left and right, thereby further enhancing the screening effect of the sand and gravel 100. There is no need to add external kinetic energy such as a motor as the whole, and the initial screening of sand and gravel can be well completed.
[0021] During specific operation, the sand and gravel 100 are discharged one by one by the feed conveyor belt 3, and then all the sand and gravel 100 fall onto the screen plate 2. There is a certain height distance between the screen plate 2 and the feed conveyor belt 3. The sand and gravel 100 rely on the inertia given by the feed conveyor belt 3, and the impact force of the free fall generated by the gravity of the sand and gravel 100 themselves. Therefore, after the sand and gravel 100 hits the screen plate 2, it will exert force on the first spring 5 and the second spring 8. Therefore, under the reaction of the first spring 5 and the second spring 8, the screen plate 2 will swing, so that the sand and gravel 100 falling on the screen plate 2 can be effectively screened.
[0022] Furthermore, in order to prevent the sieve plate 2 from swinging too much, at least one limiting rope 12 is connected to the top of the second base plate 7 of this embodiment, and the other end of the limiting rope 12 is connected to the inner wall of the gate channel 1. The limiting rope 12 has a reserved length sufficient for the normal deflection of the second base plate 7, so that the second base plate 7 can swing within a certain range.
[0023] Furthermore, after the sand and gravel 100 falls onto the screen plate 2, it is possible that it will fall directly into the stone cavity 10 before being screened. This is mainly because the sand and gravel 100 does not effectively stay on the screen plate 2. Therefore, the screen plate 2 of this embodiment is provided with at least one round rod 13 between the screen holes 9, and the round rod 13 is horizontally arranged on the screen plate 2. In this way, by relying on the establishment of the round rod 13, the residence time of the sand and gravel on the screen plate 2 can be extended, thereby completing the screening.
[0024] Furthermore, according to the size of the stones produced after the shield machine excavation, that is, the average diameter of the stones in the sand and gravel, the diameter of the round rod 13 is 2-3 cm. This size can ensure that the sand and gravel 100 have enough time to stay on the screen plate 2 and avoid the accumulation of sand and gravel 100.
[0025] Furthermore, in order to prevent the first spring 5 from deflecting during operation, the support seat 4 or the first substrate 6 of this embodiment is provided with a number of limiting posts 14 corresponding to the number of the first springs 5, and the first springs 5 are sleeved on the limiting posts 14. In this way, the limiting posts 14 can effectively play a role in vertically limiting the first spring 5.
[0026] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
