Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sampling equipment, in particular to an intelligent sampling equipment for conveyor belts. Background Art
[0002] A belt sampling machine is a device used to accurately take samples of bulk materials from a conveyor belt. It is widely used for full-section sampling in the fields of grain, coal, minerals, and chemicals to ensure the representativeness of the material samples, thereby improving the accuracy of product quality inspection.
[0003] The installation position of the existing belt sampling machine is fixed, and the shovel head can only rotate at a fixed position. During the process of the shovel head rotating for sampling, the conveyor belt is in a continuous forward state, resulting in inaccurate sampling. Moreover, the bucket will also block the conveyed grain, and there is a hidden danger of the grain falling from the conveyor belt, which urgently needs to be improved. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is that during the process of the existing belt sampling machine rotating the shovel head for sampling, the conveyor belt is in a continuous forward state, resulting in inaccurate sampling, and the bucket will also block the conveyed grain.
[0005] To solve the above problems, the technical solution of the utility model is: an intelligent sampling equipment for conveyor belts, including a conveyor belt and a sampling mechanism arranged above the conveyor belt. The sampling mechanism includes a housing. Inside the housing, a non-cylindrical support column is rotatably installed, and a motor for driving the support column to rotate is installed on the outside. And inside the housing, there is an installation block slidably sleeved outside the support column. One end of the installation block is installed with a bucket. An electric push rod is installed on the side wall of the housing. The output end of the electric push rod is fixedly connected with an installation plate. A through groove is opened at the lower part of the installation plate. The support column is located inside the through groove. And on the side of the installation plate outside the through groove, an annular slide rail is fixedly connected. A plurality of sliders are fixedly connected to the side of the installation block, which are slidably connected with the annular slide rail and sleeved outside the annular slide rail. An aggregate mechanism is arranged at the lower part of the front end of the housing.
[0006] Further, the housing is formed by assembling a plurality of protective shells together with bolts.
[0007] Further, an observation window and a controller are arranged at the upper part of the front end of the housing.
[0008] Further, the support column is a hexagonal prism.
[0009] Further, the aggregate mechanism includes a collection box. An inlet is opened at the upper part of the rear end of the collection box, and an outlet is opened at the middle part of the front end. A guide plate is arranged at the inlet, and a cover plate is installed at the outlet.
[0010] Further, the material guiding plate is inclined, and the higher end thereof extends below the edge of the conveyor belt. Protective plates are provided at both ends of the material guiding plate.
[0011] The advantages of the present utility model compared with the prior art are as follows: The motor of the present utility model drives the mounting block and the bucket to rotate through the support column. When the electric push rod extends, the mounting plate pushes the mounting block and the bucket to move along the support column through the annular slide rail and the slider. The slider is slidably connected to the annular slide rail. Therefore, when the bucket moves along the support column, it does not affect the rotation of the bucket. The extension speed of the electric push rod is the same as the speed of the conveyor belt, which enables the bucket to accurately sample the entire cross-section of the grain on the top of the conveyor belt, and can avoid the bucket from blocking the grain, improving the practicability of the device.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0018] Such as Figures 1 to 3As shown in the figure, an intelligent sampling device for a conveyor belt includes a conveyor belt 1 and a sampling mechanism arranged above the conveyor belt 1. The sampling mechanism includes a housing 2, which is formed by assembling a plurality of protective shells together with bolts. An observation window 11 and a controller 12 are provided at the upper part of the front end of the housing 2. Inside the housing 2, a support column 3 with a hexagonal prism structure is rotatably installed, and a motor 4 for driving the support column 3 to rotate is installed on the outside. Inside the housing 2, a mounting block 5 is slidably sleeved outside the support column 3, and a bucket 6 is installed at one end of the mounting block 5.
[0019] The support column 3 is a hexagonal prism. When the motor 4 drives the support column 3 to rotate, the support column 3 drives the bucket 6 to rotate through the mounting block 5, realizing cross-sectional sampling of the grain above the conveyor belt 1.
[0020] As Figure 3 and Figure 4 As shown in the figure, an electric push rod 7 is installed on the side wall of the housing 2. The output end of the electric push rod 7 is fixedly connected with a mounting plate 8. A through groove is opened at the lower part of the mounting plate 8. The support column 3 is located inside the through groove. And on the side of the mounting plate 8, an annular slide rail 9 is fixedly connected outside the through groove. A plurality of sliders 10 that are slidably connected with the annular slide rail 9 and sleeved outside the annular slide rail 9 are fixedly connected to the side of the mounting block 5.
[0021] By the telescopic movement of the electric push rod 7, the mounting plate 8 drives the annular slide rail 9 to move. The annular slide rail 9 drives the mounting block 5 to move through the sliders 10, which can adjust the position of the bucket 6 along the direction of the support column 3. Since the sliders 10 are slidably connected with the annular slide rail 9, when the bucket 6 moves along the support column 3, it does not affect the rotation of the bucket 6.
[0022] As Figure 1 and Figure 3 As shown in the figure, an aggregate mechanism is provided at the lower part of the front end of the housing 2. The aggregate mechanism includes a collection box 13. An inlet is opened at the upper part of the rear end of the collection box 13, and a material taking port is opened in the middle of the front end. A guide plate 14 is provided at the inlet, and a cover plate 15 is installed at the material taking port. The guide plate 14 is inclined, and its higher end extends to the lower part of the edge of the conveyor belt 1. Protective plates 16 are provided at both ends of the guide plate 14.
[0023] When the bucket 6 rotates to the front end inside the housing 1, the grain falls onto the guide plate 14 and slides into the inside of the collection box 13 through the guide plate 14, completing the sampling.
[0024] In specific use, grains are conveyed by the conveyor belt 1. When sampling is required, the motor 4 drives the mounting block 5 and the bucket 6 to rotate through the support column 3. The electric push rod 7 extends, causing the mounting plate 8 to push the mounting block 5 and the bucket 6 to move along the support column 3 through the annular slide rail 9 and the slider 10. The extension speed of the electric push rod 7 is the same as the speed of the conveyor belt 1, so that the bucket 6 can accurately sample the entire cross-section of the grains at the top of the conveyor belt 1. The sampled grains enter the inside of the collection box 13 through the feed inlet under the action of the material guiding plate 14. When the bucket 6 pushes all the grains to the outside of the conveyor belt 1, that is, when the bucket 6 leaves the conveyor belt 1, the electric push rod 7 contracts. When the bucket 6 returns to its original position, the electric push rod 7 and the motor 4 stop.
