Embodiment

[0023] Embodiment: a kind of biomass pellet fuel rotary vertical drop test machine, such as figure 1 , Figure 4 shown. The device includes a support 1, and the support has a fixed base and a vertical pole. The middle part of the vertical rod of the bracket is connected with the falling cylinder 2 through the rotating shaft 10, and the rotating shaft clamps the falling cylinder through two hoops 3. The drop cylinder 2 is a cylinder with a square cross section, which is divided into three sections. The hoop 3 is clamped in the middle section of the drop cylinder 2, and the two ends of the drop cylinder 2 are slidably sleeved inside the middle section. The end sections can be synchronously telescopically adjusted. Both the rotation of the falling cylinder 2 and the expansion and contraction of the two ends of the falling cylinder 2 are driven by motors. A protective ring 4 is arranged around the rotation track of the falling cylinder 2 on the support 1, and a scrap box 5 is ...

Abstract

The invention relates to a rotary type vertical drop testing machine which solves the problem that an existing falling drop test machine cannot meet a repeated drop test of easily-broken samples. The rotary type vertical drop testing machine comprises a bracket and a drop cylinder arranged on the bracket. The rotary type vertical drop testing machine is characterized in that the waist of the drop cylinder is rotatably mounted on the bracket, wherein openings are formed in two ends of the drop cylinder, openable drop plates and sieve nets are respectively arranged on the inner sides of two end parts from inside to outside along the axis direction, and a powder box for receiving powder filtered from the sieve nets is arranged right below a vertical position of the drop cylinder. According to the rotary type vertical drop testing machine, by utilizing the rotary drop cylinder which can be tested again after being rotated upside down, the automatic operation of the repeated drop test can be met in a limited space; powder can be sieved out after each test in drop test processes of easily-broken samples such as biomass granular fuels and can be weighed, and each test result can be monitored in real time simultaneously when an automatic test process is implemented.

Description

technical field [0001] The invention relates to a drop test detection device, in particular to a rotary vertical 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 pellet fuel to verify the particle integrity and mass loss rate of biomass pellet fuel under impact conditions, and to evaluate the damage degree of transportation conditions to the product , 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 falling 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 relocated to the ...
