Description

Technical Field

[0001] The utility model belongs to the technical field of tea processing equipment, and particularly relates to a material leakage prevention mechanism for a bucket elevator. Background Art

[0002] Bucket elevator is a continuous conveying machine that uses a series of buckets evenly fixed on an endless traction member to vertically lift materials. Bucket elevator uses a series of buckets fixed on a traction chain or belt to transport bulk materials upward in a vertical or nearly vertical direction. It is divided into three types: ring chain, plate chain and belt. Bucket elevators are used in many places in the tea production and processing process to lift tea from a low place to a high place and allow the tea to enter the next processing step. However, during the tea lifting process, there is a certain gap between the bucket and the bucket lifting inlet, which will cause the tea to fall from the gap to the bottom of the elevator, which is not only difficult to clean but also increases labor and is relatively wasteful. Setting the bucket close to the bucket lifting inlet will cause it to operate unsmoothly. The contact between the bucket and the bucket lifting inlet will also cause the tea in the bucket to dump. If there is too much tea in the bucket, the tea in it will fall during the lifting process.

[0003] In view of this, in order to solve the problems raised above, the utility model proposes a leakage prevention mechanism that prevents tea from falling to the bottom of the elevator by controlling the discharge amount of tea and by controlling the close cooperation of the bucket when receiving the material. The mechanism has a simple structure, is not only easy to use but also avoids waste of tea raw materials. Summary of the Invention

[0004] The utility model provides a leakage prevention mechanism for a bucket elevator with a simple and reasonable structural design, which effectively prevents tea from falling to the bottom of the elevator during the lifting process to avoid waste. The specific scheme is as follows:

[0005] A leakage prevention mechanism for a bucket elevator comprises a quantitative control component arranged on one side of the bucket elevator inlet and a leakage prevention component arranged at the bottom of the elevator, the leakage prevention component comprising an upwardly opening arc-shaped receiving plate, one end of the arc-shaped receiving plate being connected to the bucket elevator inlet, the inner bottom surface of the arc-shaped receiving plate being in close contact with the bucket elevator, a first mounting seat being horizontally provided on the side wall of the elevator on the lower side of the arc-shaped receiving plate, and a first compression spring being provided between the first mounting seat and the arc-shaped receiving plate.

[0006] Furthermore, the quantitative control component includes an electric telescopic rod, a slide and a baffle. Slides are vertically provided on both sides of the bucket lifting inlet. The baffle is slidably arranged between the two slides and its bottom end is abutted against the bottom of the feeding hopper. The electric telescopic rod is arranged on the elevator on the top side of the feeding hopper, and the output end of the electric telescopic rod is connected to the top of the baffle.

[0007] Furthermore, the quantitative control component also includes an arc-shaped blocking plate arranged on the inner side of the bucket lifting inlet, one end of the blocking plate is fixedly connected to the baffle, and the other end is arranged with a gap between it and the bottom surface of the feeding hopper.

[0008] Furthermore, a second mounting seat is horizontally provided on the side wall of the elevator on the opposite side of the first mounting seat, and a second compression spring is provided between the second mounting seat and the arc-shaped material receiving plate.

[0009] Furthermore, baffle plates are vertically provided on both sides of the arc-shaped material receiving plate, and the baffle plates are arranged along the transmission direction of the transmission component. The inner sides of the two baffle plates are respectively tightly attached to the outer sides of the two ends of the bucket.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See Figure 1-5 A leakage prevention mechanism for a bucket elevator comprises a quantitative control component 2 arranged on one side of a bucket elevator feed port 1 and a leakage prevention component 4 arranged at the bottom of an elevator 3. The leakage prevention component 4 comprises an arc-shaped receiving plate 401 with an upward opening, one end of the arc-shaped receiving plate 401 is connected to the bucket elevator feed port 1, and the other end is spaced apart from the side wall of the elevator 3. The inner bottom surface of the arc-shaped receiving plate 401 is in close contact with the bucket 5. A first mounting seat 402 is horizontally provided on the side wall of the elevator 3 on the lower side of the arc-shaped receiving plate 401, and a first compression spring 403 is provided between the first mounting seat 402 and the arc-shaped receiving plate 401.

[0023] The quantitative control component 2 includes an electric telescopic rod 201, a slide 202 and a baffle 203. Slides 202 are vertically provided on both sides of the bucket elevator inlet 1. The baffle 203 is slidably set between the two slides 202 and its bottom end is against the bottom of the feeding hopper 6. The electric telescopic rod 201 is set on the elevator 3 on the top side of the feeding hopper 6. The output end of the electric telescopic rod 201 is connected to the top of the baffle 203. The reciprocating motion rate of the electric telescopic rod 201 is controlled by the amount of tea loaded in the bucket 5 to control the amount of tea passing through the bucket elevator inlet 1 each time, thereby preventing the bucket elevator 5 from being filled with excessive tea and causing the tea to fall to the bottom of the elevator 3.

[0024] The preferred quantitative control component 2 also includes an arc-shaped baffle plate 204 arranged on the inner side of the bucket elevator inlet 1. One end of the baffle plate 204 is fixedly connected to the baffle 203, and the other end is arranged with a gap between it and the bottom surface of the feeding hopper 6.

[0025] A second mounting seat 7 is horizontally provided on the side wall of the elevator 3 on the opposite side of the first mounting seat 402, and a second compression spring 8 is provided between the second mounting seat 7 and the arc-shaped material receiving plate 401 to increase the elastic force of the arc-shaped material receiving plate 401 so that the bottom surface of the arc-shaped material receiving plate 401 is better attached to the bucket 5.

[0026] Preferably, baffle plates 9 are vertically provided on both sides of the arc-shaped material receiving plate 401. The baffle plates 9 are arranged along the transmission direction of the transmission component, and the inner sides of the two baffle plates 9 are tightly attached to the outer sides of the two ends of the bucket 5.

[0027] The ends of the two material blocking plates 9 facing away from the bucket elevator inlet 1 are both rounded structures, which makes it easier for the bucket elevator 5 to enter the arc-shaped material receiving plate 401 more normally.

[0028] The working principle of the leakage prevention mechanism of the present invention is as follows: when the elevator 3 is controlled to be started and tea leaves are poured into the feeding hopper 6, the electric telescopic rod 201 is controlled to be started, and the bucket 5 moves along the transmission direction of the elevator 3. When it moves to the arc-shaped receiving plate 401, the elastic force of the first compression spring 403 and the second compression spring 8 makes its two sides respectively close to the baffle plate 9 and the lower side close to the bottom surface of the arc-shaped receiving plate 401, so that the receiving surface of the bucket 5 is in a relatively closed state. When the bucket 5 moves to the side of the bucket lifting inlet 1, the electric telescopic rod 201 controls the baffle 203 to move upward along the slide 202. At this time, the tea leaves are discharged downward through the bucket lifting inlet 1, and the tea leaves can enter the bucket 5 along the end of the arc-shaped receiving plate 401, thereby preventing the tea leaves from falling to the bottom of the elevator 3 during the material receiving process of the bucket 5, so as to achieve the purpose of leakage prevention.
