When the staff carries out soil sample preparation in laboratory cabinet main part 1, can prepare different soil samples respectively in a plurality of sample chambers 111 that do not communicate with each other, then carry out unified clearance to experimental chamber 11 again. The laboratory cabinet that has improved among the correlation technique when carrying out the preparation of multiple soil sample, in order to avoid the interact between the different soil samples, needs carry out thorough clearance to laboratory cavity 11 before making next soil sample to spend more time, lead to the problem of the efficiency reduction of staff preparation soil sample.

Referring to fig. 4, a ventilation assembly 2 is further mounted on the experiment cabinet main body 1. The ventilation assembly 2 comprises a suction fan 21 and a number of ventilation tubes 22. The plurality of ventilation pipes 22 correspond to the plurality of sample chambers 111 one by one, and one end of each ventilation pipe 22 far away from the sample chambers 111 is communicated with the exhaust fan 21. Sample dust drifting in the sample chamber 111 is drawn out of the sample chamber 111 by the suction fan 21.

Referring to fig. 3 and 4, a ventilation inner cavity 16 and a plurality of air exhaust holes 17 are formed in the inner side wall of the sample chamber 111 facing the chamber door 13, and the plurality of air exhaust holes 17 are uniformly arranged at the middle-lower position of the inner side wall of the sample chamber 111. The plurality of air suction holes 17 are communicated with the ventilation inner cavity 16, and one end of the ventilation pipe 22 far away from the exhaust fan 21 is communicated with the ventilation inner cavity 16.

The drifting dust inside the sample chamber 111 will slowly fall down onto the bottom wall of the sample chamber 111 under its own weight. The plurality of extraction holes 17 are provided at the middle-lower position of the sample chamber 111 to facilitate extraction of heavier dust. A plurality of ventilation holes 17 that evenly lay make ventilation assembly 2 more even to the extraction of the dust that waves in the sample inner chamber, have increased the effect that ventilation assembly 2 extracted dust to a certain extent.

Referring to fig. 5 and 6, a plurality of sliding grooves 19 adapted to the partition plates 15 are formed in the bottom wall of the experiment chamber 11, a plurality of groups of fixing assemblies 18 are arranged on the top wall of the experiment chamber 11, the plurality of sliding grooves 19, the plurality of partition plates 15 and the plurality of groups of fixing assemblies 18 correspond to one another one by one, and the partition plates 15 are connected with the experiment cabinet main body 1 in the sliding grooves 19 in a sliding manner.

The sliding groove 19 is vertically arranged on the bottom wall of the experiment chamber 11 at a position corresponding to the partition plate 15, and the bottom of the partition plate 15 extends into the sliding groove 19. The fixing assembly 18 includes a mounting seat 181 and a fixing member 182 for fixing the partition 15 and the mounting seat 181, and the fixing member 182 may be a fixing pin or a fixing bolt, and the embodiment is described by selecting a fixing bolt.

The mounting seat 181 has a plate-like structure. The mounting seat 181 is fixedly connected to the top wall of the experimental chamber 11 at a position corresponding to the partition 15, and two end faces of the mounting seat 181 in the length direction are respectively attached to and fixedly connected to the inner wall of the experimental chamber 11. A first fixing hole 1811 is formed in the center of the mounting seat 181, a second fixing hole 151 is formed in the partition 15 at a position corresponding to the first fixing hole 1811, in this embodiment, the second fixing hole 151 is a threaded hole adapted to a fixing bolt, and the fixing member 182 passes through the first fixing hole 1811 and the second fixing hole 151 to mount the partition 15 and the mounting seat 181 together.

When the experiment in the experiment cabinet needs a large space to perform the experiment of the sample, the worker can take out the fixing member 182 first, so that the partition plate 15 and the mounting seat 181 are separated from each other. The diaphragm 15 is then placed back into the slide groove 19. The different sample chambers 111 are now interconnected to form the laboratory chamber 11, so that the staff can have a larger space for subsequent experiments.

The partition 15 is provided with an elastic sealing ring 152. The sealing ring 152 is a square ring structure matched with the partition board 15, an annular groove 1521 matched with the partition board 15 is formed in the inner side of the sealing ring 152, and corners of the partition board 15 extend into the sealing ring 152 and are fixedly connected with the sealing ring 152. When the baffle 15 is installed on the mount pad 181, the baffle 15 and the inner wall of the experiment chamber 11 generate a certain extrusion force on the sealing ring 152, and the sealing ring 152 generates a certain deformation, so that the gap between the baffle 15 and the inner wall of the experiment chamber 11 is reduced, and the tightness between the sample chambers 111 adjacent to the baffle 15 is increased to a certain extent.

The side wall of the mounting seat 181 facing the partition 15 is horizontally and fixedly connected with a positioning strip 1812, and when a worker moves the partition 15 upwards so that the upper surface of the sealing ring 152 abuts against the lower surface of the positioning strip 1812, the first fixing hole 1811 is aligned with the second fixing hole 151, so that the worker can more easily mount the partition 15 and the mounting seat 181 together correspondingly.

The cross-section of the sealing ring 152 is circular and the locating bar 1812 is an arcuate plate that conforms to the arc of the sealing ring 152. After the partition 15 is installed, the contact area between the positioning bar 1812 and the sealing ring 152 is increased, and the sealing performance between the mounting seat 181 and the partition 15 is increased to some extent.

Referring to fig. 5, in order to facilitate cleaning of dust in the sample chamber 111, an experiment tray 1111 is placed on the bottom wall in the sample chamber 111. After sample preparation is complete, the vast majority of the scattered sample soil will fall into tray 1111. The staff can take out the back with tray 1111 and handle for it is more simple and convenient when the staff clears up in to sample cavity 111.

The implementation principle of preparing experimental cabinet for soil sample of the embodiment of this application is: when the operator needs to prepare a plurality of soil samples, the spacer 15 is first moved up until the upper side of the sealing ring 152 abuts against the lower surface of the positioning strip 1812. The partition 15 is then mounted with the mount 181 using the fixture 182.

At this time, the experiment chamber 11 is divided into a plurality of sample chambers 111 which are not communicated with each other, and workers can prepare different soil samples in the sample chambers 111.

After the exhaust fan 21 is opened, dust drifting in the sample chamber 111 in the process of preparing a sample sequentially passes through the exhaust hole 17, the ventilation inner cavity 16 and the ventilation pipe 22 and then is extracted out of the sample chamber 111 by the exhaust fan 21, so that the influence of dust drifting in the sample chamber 111 on the environment of a laboratory is reduced.

When a worker needs a large experimental area and performs other experiments, the fixing member 182 is screwed to separate the partition 15 from the mounting seat 181, and then the partition 15 is lowered into the sliding groove 19. At this time, the plurality of sample chambers 111 are communicated with each other to form a large experiment chamber 11, so that the worker can perform other experiments.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
