Embodiment

[0022] Embodiment: a kind of three-level drop test machine, such as figure 1 , image 3 shown. The device includes a bracket 1, the upper surface of the bottom of the bracket is a drop floor 5, one side of the bracket is provided with a vertical pole, and the top of the pole is provided with an openable lifting platform 2, and the lifting platform 2 is composed of two symmetrical left and right pieces The pivot shaft of the board is located in the middle of the board, the middle part of the lifting platform, that is, the junction of the two boards, can be opened downwards, and a stopper is provided below the outer sides of the two boards to prevent the lifting platform from opening in reverse. Block 3, the block 3 is arranged on the side baffles 4 on both sides of the lifting platform.

[0023] Two conversion layers 6 are arranged at equal intervals between the lifting platform and the drop floor, and side baffles 4 are arranged on both sides of the lifting platform, the con...

Abstract

The invention relates to a multi-stage drop test machine to solve the problem that an existing drop test machine can not meet the requirement for multiple drop tests of samples easy to break. The multi-stage drop test machine comprises a support, a drop bottom plate is arranged at the bottom of the support, and the upper portion of the support is provided with a lifting platform which can be opened and closed. The multi-stage drop test machine is characterized in that a plurality of transfer layers are arranged between the lifting platform and the drop bottom plate; each transfer layer comprises a bearing plate which bears samples dropping from the upper layer and can be opened downwards, a lifting plate is arranged below the bearing plate and can be opened downwards to throw the samples, screen cloth is obliquely arranged between the bearing plate and the lifting plate, a chip collecting tank is arranged below the screen cloth, and an opening is formed in the lowest position of the screen cloth and communicated with the upper portion of the lifting plate. Series connection of a multi-layer transfer layer test and the multiple drop tests is adopted, during the multiple drop tests, chips are screened out, and the participating samples are thrown into the next test, and the requirement for the multiple drop tests of the samples easy to break is met.

Description

technical field [0001] The invention relates to a drop test detection device, in particular to a multi-stage drop test machine. Background technique [0002] Many products need to be tested for impact resistance before production and finalization, such as mobile phones, trolley cases, etc., which are generally tested by drop test machines. For fragile samples such as biomass pellet fuel, it is also necessary to test the impact resistance of biomass fuel pellets to verify the particle integrity of biomass pellet fuel under impact conditions and improve product quality. The traditional vertical drop test machine is generally set as a lifting platform at a certain height, and the floor below is the drop floor. The product falls from the lifting platform to the floor for a simulated impact. When multiple tests are required, the product needs to be manually replaced on the Lift the platform, or use a lifting device to re-lift the product. For biomass pellet fuel, the particles ...
