Description

Technical Field

[0001] The utility model relates to a test piece waste cleaning device, in particular to a test piece waste conveying device for a concrete compressive strength pressure test experiment. Background Art

[0002] Concrete compressive strength testing is one of the most common testing items in engineering projects, and there is a great demand in actual testing. In the past, most concrete compressive strength tests were highly dependent on manual labor. The sample information input, sample storage and transportation, sample strength testing, post-test cleaning, data collection and comprehensive processing in the concrete compressive strength test process all require manual operation, which is labor-intensive and unsafe, time-consuming and labor-intensive, and has low testing efficiency.

[0003] In order to improve the detection efficiency and reduce the labor intensity, automatic concrete pressure testing equipment has been developed, such as the mechanical device for concrete compression test disclosed in patent CN210064448U, which includes an outer frame and a pressure testing machine located in the middle of the outer frame, a feeding and discharging device located in the inner cavity of the outer frame is installed on one side of the pressure testing machine, a placing material box is installed on the side of the feeding and discharging device, and a grabbing mechanism is provided between the feeding and discharging device and the placing material box, and a feeding conveyor line with an end extending to the outside of the outer frame is provided in the middle of the outer frame, and the feeding conveyor line is horizontal in the middle position and tilted at both ends, and the pressure testing machine, the feeding and discharging device, the placing material box and the grabbing mechanism are divided into two groups and form a left-right symmetrical structure on the left and right sides of the feeding conveyor line, and the tonnage of the two pressure testing machines is different. In the concrete compression test, this technical solution only needs to manually place the concrete test block in the material box, and the work of taking, loading and unloading, sending for inspection and dust removal of the concrete test block is directly completed in an integrated process, which improves production efficiency while reducing labor intensity and labor costs. However, in the above technical solution, there is no waste guide groove at the end of the unloading conveyor line, which is not convenient for collecting or transferring waste; when the second cylinder pushes the waste specimen after the experiment from the working platform of the press, the debris of the waste specimen is easy to fall into the gap between the two sides of the unloading conveyor line belt and the frame, which will cause mechanical failure and reduce the life of the conveyor belt. Summary of the invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a test piece waste conveying device to solve the problems existing in the background technology.

[0005] The technical solution adopted by the utility model to achieve the above-mentioned purpose is:

[0006] A specimen waste conveying device includes a belt conveyor, which is characterized in that: side box plates are provided on both sides of the frame of the belt conveyor, and a dust cover plate is provided between the upper parts of the two side box plates; it also includes a first material guide trough and a second material guide trough, the first material guide trough is used to receive the specimen waste and waste residue pushed out from the testing machine workbench; the second material guide trough is arranged at the outlet end of the belt conveyor.

[0007] In the above-mentioned specimen waste conveying device, one end of the first material guide trough is connected to the side of the testing machine workbench, and the other end is inclined downward away from the testing machine and located on the upper part of the belt of the belt conveyor.

[0008] By adopting the above technical solution, side box plates are provided on both sides of the frame of the belt conveyor to prevent the waste materials and slag of the test piece from being scattered outside the belt conveyor; a dust cover plate is provided between the upper parts of the box plates on both sides to prevent dust from flying, which can effectively ensure the working environment and the health of the operators. The side of the test machine workbench is connected to the first material guide trough, and the outlet end of the belt conveyor is provided with a second material guide trough, which can ensure that the waste materials and slag of the test piece are smoothly transferred to the next process and prevent them from being scattered outside the belt conveyor.

[0009] In the above-mentioned specimen waste conveying device, a guard plate is provided on the inner side surface of the side box plate, between the belt of the belt conveyor and the first material guide trough.

[0010] Furthermore, the upper side surface of the guard plate is inclined obliquely downward from the side box plate toward the center of the belt.

[0011] By adopting the above technical solution, when the waste specimen is pushed out from the working platform of the press after the test, the debris of the waste specimen is not easy to fall into the gap between the two sides of the belt and the frame, thereby reducing mechanical failures and increasing the service life of the conveyor belt.

[0012] In the above-mentioned specimen waste conveying device, the belt is a skirt baffle conveyor belt.

[0013] By adopting the above technical solution, the belt adopts a skirt baffle conveyor belt, which is composed of a wavy skirt, a baffle and a base belt. The skirt is usually designed to be a skirt-shaped, presenting a continuous wave shape, and the skirt can protect the test piece waste from spilling to both sides. The baffle is spaced and arranged horizontally on the base belt, at 90 degrees to the running direction of the belt, mainly to prevent the test piece waste from sliding down.

[0014] Furthermore, a downwardly extending rib is provided on one end of the guard plate close to the center of the belt, and the rib is located on the inner side of the skirt of the skirt baffle conveyor belt.

[0015] By adopting the above technical solution, the guard plate extending downward is located on the inner side of the skirt of the skirt baffle conveyor belt, which can further ensure that the test piece waste and waste residue pushed out from the testing machine workbench falls into the center of the belt and does not fall into the gap between the two sides of the belt and the frame.

[0016] Beneficial Effects

[0017] 1. Side boxes are installed on both sides of the frame of the belt conveyor to prevent the waste materials and slag of the test piece from being scattered outside the belt conveyor; dust cover plates are installed between the upper parts of the two side boxes to prevent dust from flying, which can effectively ensure the working environment and the health of the operators. The setting of the first guide trough and the second guide trough can ensure that the waste materials and slag of the test piece are smoothly transferred to the next process and prevent them from being scattered outside the belt conveyor.

[0018] 2. A protective plate is set on the inner side of the side box plate. When the waste specimens are pushed out from the working platform of the press after the test, the debris of the waste specimens is not easy to fall into the gap between the two sides of the belt and the frame, which reduces mechanical failures and increases the service life of the conveyor belt.

[0019] 3. The belt adopts a skirt baffle conveyor belt. The skirt can protect the waste of the test piece from spilling to both sides. The baffles are arranged at intervals and horizontally on the base belt to prevent the waste of the test piece from sliding down. BRIEF DESCRIPTION OF THE DRAWINGS
