Description

Technical Field

[0001] The utility model relates to the technical field of sampling and detecting cement-stabilized crushed stone inorganic binder, in particular to a sampling auxiliary device for cement-stabilized crushed stone inorganic binder mixing equipment. Background Art

[0002] During the construction of cement-stabilized crushed stone inorganic binder, it is necessary to take samples every day to test the grading and screening of the mixture. The sampling process must be carried out when the mixing equipment is shut down. Specifically, a section of the transport belt corresponding to the mixing equipment is randomly cut off and all the mixture in the area is collected. However, when sampling in the cut-off area, due to the certain slope of the transport belt and the incomplete coverage of the belt width after interception by a shovel, it is easy to cause coarse particles in the mixture outside the intercepted area to be mixed into the sample in the intercepted section under the action of gravity, resulting in the sampled test sample being unrepresentative, thereby affecting the detection accuracy of the grading and screening of the mixture. Utility Model Content

[0003] The purpose of the present application is to provide a sampling auxiliary device for cement-stabilized crushed stone inorganic binder mixing equipment to solve the problem that the existing interception sampling method easily causes coarse particles in the mixture outside the interception area to be mixed into the sample in the interception section under the action of gravity, resulting in the sampled test sample being unrepresentative, thereby affecting the detection accuracy of the mixture gradation screening.

[0004] In order to solve the above technical problems, the present application provides a sampling auxiliary device for cement-stabilized crushed stone inorganic binder mixing equipment, comprising:

[0005] Baffles are arranged in pairs, the width of the baffles corresponds to the conveying belt, the bottom side of the baffles is arranged in an arc shape and conflicts with the conveying belt, a connecting rod is fixed on the upper side of the baffle, an operating handle is fixed on the upper end of the connecting rod, and inclined support rods are respectively arranged on both sides of the baffles, and the lower ends of the inclined support rods conflict with the conveying belt.

[0006] Based on the above embodiment, as a preferred implementation manner, the height of the baffle protruding from the conveyor belt is 15 centimeters.

[0007] On the basis of the above embodiment, as a preferred implementation manner, the number of the inclined support rods is two, and the two inclined support rods are respectively arranged on both sides of the baffle.

[0008] It is necessary to explain in detail in the solution that the operating handle is also provided with grab rings near both ends thereof.

[0009] On the basis of the above embodiments, as a preferred implementation manner, the grab ring, the operation handle and the connecting rod are integrally formed.

The width of the baffles corresponds to the conveying belt. The bottom side of the baffles is arc-shaped and abuts against the conveying belt. A connecting rod is fixed on the upper side of the baffles, and an operation handle is fixed at the upper end of the connecting rod. Inclined support rods are respectively arranged on both sides of the baffles, and the lower ends of the inclined support rods abut against the conveying belt. During use, the two baffles can be placed at corresponding positions on the conveying belt by means of the operation handle, that is, the two baffles are respectively placed at the upstream and downstream positions of the conveying belt. The arc-shaped part at the bottom side of the baffles can well abut against the upper side of the conveying belt, intercepting a sampling area on the conveying belt, effectively preventing coarse particles in the mixture outside the sampling area from mixing into the sample in the intercepted section under the action of gravity, ensuring the representativeness of the test sample after sampling, and improving the detection accuracy of the gradation screening of the mixture; at the same time, the baffles can be supported by the inclined support rods to prevent the baffles from tipping left and right.
