Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor sampling technology, specifically relating to a sampling device applied to belts. Background Technology

[0002] Currently, sampling for unloading goods on conveyor belts is done manually using a sampling shovel. This method requires constant monitoring of the belt's operating status and flow rate, which is labor-intensive. Furthermore, the sampling personnel standing on one side of the belt while using the sampling shovel poses certain safety risks. Manual sampling on conveyor belts is also highly arbitrary and lacks representativeness.

[0003] To address the aforementioned sampling deficiencies, existing technology has designed sampling equipment that samples from the middle of the conveyor belt. However, when sampling from the middle, if the transport volume is large, only the upper layer of concentrate on the belt can be sampled, and the lower layer cannot be sampled, resulting in a slight sampling error.

[0004] In view of the above factors, a sampling device for use on a belt is provided, which improves the labor efficiency of sample collection, reduces the instability of manual sampling quality, and reduces the labor intensity of operators. Utility Model Content

[0005] The purpose of this invention is to provide a sampling device for use on belts, so as to solve the problems mentioned in the background art.

[0013] Furthermore, the sampling chamber is set horizontally or at an angle of 15-30 degrees.

[0014] Furthermore, the receiving bin is a barrel structure, and the receiving bin is fixedly located in a positioning groove on the mounting frame.

[0029] like Figure 1-5 As shown, a sampling device applied on a belt includes a transmission belt 1 and a fixed chamber 2. The fixed chamber 2 is located near the belt head pulley 7 of the transmission belt 1. A movable sampling component 3 is provided inside the fixed chamber 2. The sampling component 3 includes several sampling chambers 4 arranged in parallel. The front end of the sampling chamber 4 is set as an open baffle structure, and the rear end of the sampling chamber 4 is connected to a conveying pipe 5.

[0031] The fixed compartment 1 is connected to the plane of the mounting frame that is fixed to the transmission belt 1 by bolts or welding.

[0032] To facilitate sampling operations in the direction of the conveyor belt drive during use, the sampling chamber 4 is a semi-enclosed structure formed by steel structure. The front section of the sampling chamber is open and the rear section is closed. The rear section of the sampling chamber 4 is connected to the conveying pipe 5.

[0033] The fixed compartment is open on the side closest to the belt pulley 7, and either end of the front or rear end face of the fixed compartment is connected to a side door 8 via a hinge. The side door 8 facilitates maintenance and retrieval of the receiving compartment during use.

[0034] To facilitate the support of the sampling chamber 4 at different heights by setting a Z-shaped mounting frame 9 during use, the sampling chamber 4 is fixed on the Z-shaped mounting frame 9, which is movably connected to the fixed chamber 2.

[0035] To facilitate disassembly and replacement during use, the mounting bracket 9 is bolted to the bottom surface of the fixed chamber 2, and the mounting bracket 9 is spaced apart along the transverse direction of the belt pulley 7.

[0036] To facilitate sampling operations by using a power source to move the mounting frame 9 closer to the belt pulley 7, the bottom of the mounting frame 9 is equipped with a slider 1 connected to a slide rail 11 at the bottom of the fixed chamber. The rear end of the mounting frame is connected to a hydraulic cylinder 12, and the output end of the hydraulic cylinder 12 is connected to the mounting frame.
