The connecting part 13 is connected with a driving mechanism (not shown in the drawings), the connecting part 13 can be a connecting lug plate, and the driving mechanism drives the box body 1 to do reciprocating linear motion under the driving of a power device (not shown in the drawings). The water inlet of the drain hole 14 is communicated with the inner cavity, and the water outlet is communicated with a drain system (not shown in the drawing). The water flowing into the tank 1 flows into the drainage system through the drainage hole 14 and is discharged. In addition, a filtering device (not shown in the drawing) is installed in the drain hole 14, for filtering moisture generated in the reaction process of the materials such as garbage, so as to prevent particulate matters such as garbage from entering the drain system.
In addition, the air outlet of the air supply hole 12 is preferably higher than the water inlet of the water discharge hole 14 so as to prevent water from flowing into the air supply system from the air supply hole 12.
The feeding slide plate 2 is obliquely arranged at the opening of the box body 1 and covers the whole opening, when the panel of the box body 1, which is provided with the air supply hole 12, is horizontally placed, the included angle between the feeding slide plate 2 and the panel of the box body 1, which is provided with the air supply hole 12, is a, and the included angle a is 30-60 degrees, so that the garbage can automatically fall on the feeding slide plate 2 by utilizing the gravity of the garbage, and the purpose of conveying the garbage from one end of the feeding slide plate 2 to the other end is achieved. Preferably, the angle a is 45 degrees, so that the waste on the material plate is not transported too fast because the angle of inclination is too large, nor too slow because the angle of inclination is too small. The feeding slide plate 2 is provided with a first through hole 21 and a first cutting edge 22, and the first through hole 21 is communicated with the inner cavity 11. The first through hole 21 is used for supplying air to the garbage on the feeding slide plate 2 so as to ensure the ventilation of the garbage and enhance the reaction efficiency. Meanwhile, the excessive moisture in the garbage may also flow into the case 1 from the first through hole 21 and then be discharged via the drainage system. The first cutting edge 22 is located at the end of the feed slide 2 remote from the air supply opening 12, i.e. at the highest point of the feed slide 2. The first cutting edge 22 is used to cut the waste passing over its cutting edge to facilitate the complete reaction of the waste.

The lateral pressing blade 4 is used for pressing and cutting materials, is arranged on one side of the side baffle 3 facing the feeding slide plate 2, and has an included angle b with the feeding slide plate 2 of 8-15 degrees, so that when garbage passes through the feeding slide plate 2, the garbage is moved to be close to the feeding slide plate 2, namely, the garbage is pressed. Preferably, the included angle b is equal to 10 ° so as to ensure the trafficability of the garbage while the garbage is being treated.
The main crushing blade 4 and the auxiliary crushing blade 6 are used for cutting garbage passing through the feeding slide plate 2, and the height of the main crushing blade 4 is larger than that of the auxiliary crushing blade 6, so that the main crushing blade and the auxiliary crushing blade are matched in height so as to facilitate better cutting. The main crushing blade 4 and the auxiliary crushing blade 6 are sequentially and alternately arranged on the feeding slide plate 2, and the structure is beneficial to garbage cutting. And near the lateral material pressing blade 4 is a secondary crushing blade 6, which is beneficial to the lateral material pressing blade 4 to press garbage.
In one embodiment, the first through hole 21 becomes smaller from its air inlet to its air outlet, i.e. the air inlet of the first through hole 21 is larger and the air outlet is smaller. This structure increases the pressure of the air flow flowing out of the air outlet by narrowing the air outlet of the first through hole 21, so as to prevent the material from falling down through the hole.
In one embodiment, the other end of the feed slide 2 is provided with a second through hole 23, the second through hole 23 being located at the end of the feed slide 2 near the air supply hole 12 and communicating with the inner chamber 11, i.e. the lowest part of the feed slide 2. The air from the air supply hole 12 forms a protective air layer at the joint between the garbage and the fire grate segments through the second through holes 23 so as to prevent the garbage from sliding into the joint between the fire grate segments, thereby affecting the sealing effect. The second through hole 23 is a bar-shaped hole extending from one side of the feed slide plate 2 to the other side and penetrating almost the entire autonomous material sliding surface of the feed slide plate 2. Therefore, a protective air layer can be formed at the whole joint to prevent the garbage from sliding into the joint between the fire grate segments to the maximum extent. The moisture in the garbage may flow into the casing 1 through the second through hole 23, and then be discharged into the drainage system through the drainage hole 14.
In one embodiment, the second through hole 23 becomes smaller from its air inlet toward its air outlet. According to the structure, the air outlet of the second through hole 23 is reduced, so that the air pressure of the air outlet of the second through hole 23 is increased, and the materials are prevented from sliding downwards into the contact gap.
