Abstract
Description
Technical Field
[0001] This utility model belongs to the field of belt conveyor material conveying technology, and in particular relates to a device for collecting timed and quantitative material samples for belt conveyors. Background Technology
[0002] Belt conveyors are short for belt conveyors. They come in stationary and mobile types. They are simple in structure, highly efficient, and are continuous conveying machines that use flexible conveyor belts as material-bearing and traction components. However, each time material is sampled, it needs to be collected manually. But manually collecting materials conveyed on a running belt conveyor is dangerous, and because the sampling of deep and shallow layers is unstable, the weight and volume of the samples extracted each time are not consistent. Utility Model Content
[0003] In view of this, the present invention aims to propose a timed and quantitative material sample collection device for belt conveyors, in order to solve the problems of the dangers of manually collecting materials transported on operating belt conveyors in the prior art, and the inconsistency in the weight and volume of samples extracted each time due to the instability of shoveling deep and shallow layers.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A device for collecting timed and quantitative material samples from a belt conveyor includes a telescopic cylinder, a collection trough, a discharge plate, a sampling impeller, and a leakage cylinder. The fixed end of the telescopic cylinder is installed at one end of a working platform, and the telescopic end is connected to the collection trough. A belt conveyor is installed at the other end of the working platform via a support frame. The sampling impeller is installed above the belt conveyor, and the blades of the sampling impeller are in contact with the surface of the belt conveyor. A discharge plate is provided on the side of the collection trough away from the telescopic cylinder. The discharge plate is installed on the working platform. A leakage cylinder is provided between the belt conveyor and the discharge plate. The leakage cylinder is connected to the working platform, and a collection box is provided below the leakage cylinder.
[0005] Furthermore, the sampling impeller has several blades, which are evenly distributed circumferentially.
[0006] Furthermore, when the sampling impeller has four blades, there are three belt conveyors, with the middle belt conveyor set horizontally and the other two symmetrically installed on both sides of the middle belt conveyor and set at an angle.
[0007] Furthermore, the collection trough is mounted on multiple pulleys, which are mounted on the work platform.
[0008] Furthermore, the sampling impeller is connected to the drive end of the drive motor, the fixed end of the drive motor is connected to the bracket, the bracket is installed on the working platform, and the bracket is located above the belt conveyor.
[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the collection trough first extends to the lower side of the belt conveyor, and then the sampling impeller rotates a set number of times. The blades on the sampling impeller scrape the material on the belt conveyor and it falls into the collection trough at the lower side. Then, the collection trough is retracted by the telescopic cylinder. Under the obstruction of the unloading plate, the material falls into the collection box below through the discharge cylinder. The sampling time is controlled by setting the number of rotations of the sampling impeller, and the sampling amount is controlled by the number of evenly distributed blades on the sampling impeller, thereby meeting different sampling needs.
[0010] 2. This utility model eliminates the need for workers to approach the operating conveyor belt, greatly improving safety. Furthermore, the use of a sampling impeller reduces labor intensity, eliminating the need for manual sampling.
[0011] 3. This utility model can obtain samples more accurately, ensure uniform scraping depth and scraping amount, and reduce human influence. Attached Figure Description

The illustrative embodiments of the utility model and their descriptions are used to explain the utility model and do not constitute an undue limitation of the utility model. In the drawings: Figure 1 This is a schematic diagram of the structure of a timed and quantitative material sample collection device for a belt conveyor, as described in this utility model.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present utility model can be combined with each other, and the described embodiments are only some embodiments of the present utility model, not all embodiments.
[0015] Detailed Implementation Method 1: See Figure 1This embodiment describes a timed and quantitative material sample collection device for a belt conveyor, comprising a telescopic cylinder 1, a collection trough 2, a discharge plate 3, a sampling impeller 6, and a leakage cylinder 7. The fixed end of the telescopic cylinder 1 is installed at one end of a working platform, and the telescopic end is connected to the collection trough 2. A belt conveyor 5 is installed at the other end of the working platform via a support frame 4. The sampling impeller 6 is installed above the belt conveyor 5, and the blades of the sampling impeller 6 are in contact with the surface of the belt conveyor 5. The discharge plate 3 is located on the side of the collection trough 2 away from the telescopic cylinder 1. The discharge plate 3 is installed on the working platform. A leakage cylinder 7 is located between the belt conveyor 5 and the discharge plate 3. The leakage cylinder 7 is connected to the working platform, and a collection box is located below the leakage cylinder 7. The sampling impeller 6 is connected to the drive end of a drive motor, and the fixed end of the drive motor is connected to a bracket 8. The bracket 8 is installed on the working platform and is located above the belt conveyor 5.
[0016] The collection trough 2 is first extended to the side and below the belt conveyor 5. Then, the sampling impeller 6 rotates a set number of times, scraping the material on the belt conveyor 5 through the blades on the sampling impeller 6 and dropping it into the collection trough 2 below. Then, the collection trough 2 is retracted by the telescopic cylinder 1. Under the obstruction of the unloading plate 3, the material falls into the collection box below through the discharge cylinder 7. The sampling time is controlled by setting the number of rotations of the sampling impeller 6, and the sampling amount is controlled by the number of evenly distributed blades on the sampling impeller 6. In this way, different sampling needs can be met, and the sampling effect of timed and quantitative sampling can be achieved.
[0017] Detailed Implementation Method 2: See Figure 1 In this embodiment, the sampling impeller 6 has a plurality of blades, which are evenly distributed in a circumferential direction. The interval between each blade is the same. Therefore, during the rotation of the sampling impeller 6, quantitative sampling can be performed, and the sampling amount can be adjusted by evenly arranging different numbers of blades according to the sampling requirements.
[0018] Furthermore, when the sampling impeller 6 has four blades, the belt conveyor 5 has three units. The middle belt conveyor 5 is horizontally positioned, and the other two are symmetrically installed on both sides of the middle belt conveyor 5 and are inclined. The inclined arrangement of the belt conveyors 5 on both sides is to ensure that the surface of the three belt conveyors 5 can contact the top of each blade, so that the material on each belt conveyor 5 can be scraped and collected. In addition, the use of three belt conveyors 5 increases the amount of material transported, which improves the collection efficiency compared to the transport of a single belt conveyor 5.
[0019] Furthermore, increasing the size of the belt conveyor 5 can also improve collection efficiency.
[0020] Detailed implementation method 3: See Figure 1In this embodiment, the collection trough 2 is mounted on multiple pulleys 9, which are mounted on the working platform to ensure that the collection trough 2 can move smoothly during extension and retraction, avoiding jamming of the collection trough 2 and thus affecting the collection effect.
[0021] The specific embodiments of this utility model disclosed above are merely illustrative of the present utility model. These specific embodiments do not exhaustively describe all details, nor do they limit the utility model to only the described embodiments. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
