At the upper end, a discharge port 22 is arranged at the lower end of the discharge chamber 23, and the waste compression structure 4 is connected with the lower end of the discharge chamber 23 through the discharge port 22, and the negative pressure dust collecting mechanism 3 is connected with the upper end of the discharge chamber 23, and the negative pressure dust collecting mechanism 3 generates negative pressure to absorb dust and waste to enter the discharge chamber 23 through the feeding structure 21, and the negative pressure dust collecting mechanism 3 absorbs dust and collects it from the discharge chamber 23 under negative pressure, and the waste passes through the discharge chamber 23 and falls into the waste compression mechanism 4, and the waste compression mechanism 4 compresses and collects the waste, thereby realizing automatic waste collection and preventing dust from overflowing.

[0024] Please continue to refer to Figure 1 As shown, the feed structure 21 includes a feed port 211, a filter screen 212 and a pulse blowing structure 213. The feed port 211 is connected to the material drop chamber 23 and the outside of the waste machine frame 1. The feed port 211 negatively absorbs dust and waste into the material drop chamber 23. The filter screen 212 is installed at the upper end of the material drop chamber 23, and the feed port 211 passes through the filter screen 213 to separate dust and waste. The filter screen 212 will block the waste from moving upward, so that the waste passes through The material dropping chamber 23 enters into the waste compression mechanism 4, and the dust passes through the filter 212 and is collected by the negative pressure dust collecting mechanism 3. The pulse blowing structure 213 is installed on the top of the material dropping chamber 23. The pulse inflation structure 213 blows air into the material dropping chamber 23 regularly through a pulse valve to avoid blockage of the material dropping chamber 23. The cross-section of the material dropping chamber 23 is a rectangular and trapezoidal alternating splicing structure, which is used to guide the waste into the waste compression mechanism 4 and can buffer the waste.

[0025] Please combine Figure 1-4As shown, the negative pressure dust collecting mechanism 3 includes a dust collecting duct 35, a dust collecting box 31, a primary filter assembly 32, a secondary filter assembly 33 and a dust collecting fan 34. The primary filter assembly 32 is installed at the upper end of the dust collecting box 31, the secondary filter assembly 33 is installed at the upper end of the primary filter assembly 32, and the dust collecting fan 34 is installed at the upper end of the secondary filter assembly 33.

The primary filter assembly 32 is used to filter large particles of dust so that large particles of dust fall into the dust collecting box 31, the secondary filter assembly 33 is used to filter small particles of dust, the dust collecting fan 34 is used to generate negative pressure, and the filtered air is directly discharged to the outside of the waste machine frame 1, and the dust collecting box 31 is a pull-out dust collecting box to facilitate collection and dumping of large particles of dust.

[0026] The second filter assembly 33 includes a second filter chamber 331 and a secondary filter 332. The secondary filter 332 is installed at the upper end of the second filter chamber 331 and is close to the dust collecting fan 34. The secondary filter 332 is used to absorb small particles of dust to prevent the small particles of dust from being discharged to the outside by the dust collecting fan 34.

[0027] The first filter assembly 32 includes a spiral pulse assembly 323, a first filter chamber 321, a filter cartridge 322 and a pressure difference alarm system (not shown in the figure). The first filter chamber 321 is connected to the dust box 31, and the first filter chamber 321 is connected to the second filter chamber 331 through the filter cartridge 322. The spiral pulse assembly 323 is installed in the second filter chamber 331 and aligned with the filter cartridge 322. The filter cartridge 322 is used to filter large particles of dust. The spiral pulse assembly 323 regularly blows the positive pressure gas in the gas tank into the filter cartridge 322 to blow away the dust adhered to the filter cartridge 322, so as to achieve the effect of cleaning the filter cartridge 322. The pressure difference alarm system includes a first pressure difference sensor and a second pressure difference sensor. The first pressure difference sensor is installed in the first filter chamber 321, and the second pressure difference sensor is installed in the second filter chamber 331. The first pressure difference sensor detects the pressure difference P1 in the first filter chamber 321, and the second pressure difference sensor detects the pressure difference P2 in the second filter chamber 331. The set pressure difference value △P is compared with the difference between the pressure difference P1 in the first filter chamber 321 and the pressure difference P2 in the second filter chamber 331. When △P≥|P1-P2|, the negative pressure dust collecting mechanism 3 operates normally; when △P<|P1-P2|, it means that the filter cartridge 322 is blocked, the pressure difference alarm system alarms, and the filter cartridge 322 is checked and replaced to ensure that the negative pressure dust collecting mechanism 3 can operate normally.

[0028] The dust collecting pipe 35 is provided with an anti-backflow structure 351, which is installed at the connection between the dust collecting pipe 35 and the first filter chamber 321. When the spiral pulse assembly 323 cleans the filter cartridge 322, the first filter chamber 321 is in a positive pressure state, and the anti-backflow structure 351 can prevent dust from passing through the dust collecting pipe 35 and entering the material bin chamber 23. The anti-backflow structure 351 includes a guide cover 3511, a spring hinge 3512 and a spoiler 3513. The spoiler 3513 is hingedly arranged at both ends of the guide cover 3511 through the spring hinge 3512. When there is a negative pressure in the first filter chamber 321 (such as Figure 4 As shown in b), that is, when the dust collecting fan 34 is started, the spoiler 3513 is opened relative to the guide cover 3511 by the negative pressure, so that the integrated pipeline 35 is connected with the first filter chamber 321. When the first filter chamber 321 is under positive pressure (as shown in Figure 4 As shown in a in the figure, when the spiral pulse assembly 323 is started, the spoiler 3513 is closed under the drive of the spring hinge 3512, that is, the integrated duct 35 and the first filter chamber 321 are separated, so that the positive air pressure generated by the spiral pulse assembly 323 cannot pass through the integrated duct 35 to prevent dust from entering the material drop bin 23. In particular, the dust collecting duct 35 is also provided with an anemometer (not shown in the figure), which is installed in the dust collecting duct 35 to test the negative pressure wind speed in the dust collecting duct 35, and the blockage degree of the primary filter assembly 32 is monitored by comparing the wind speed generated by the dust collecting fan 34 with the negative pressure wind speed in the dust collecting duct 35.

When the through-shooting sensor 431 senses that the material is full, the pushing assembly 44 drives the waste in the compacting chamber 42 to move toward the gate assembly 45 to compact the waste. After the compaction is completed, the gate assembly 45 is driven to open, and the pushing assembly 44 pushes the waste to the waste trolley 46 for storage.

After the gate 451 is lifted, the mechanical latch 454 abuts against the gate 451, thereby clamping the gate 451 to prevent the gate 451 from falling during maintenance by the operator, causing a safety hazard.

[0031] The push assembly 44 includes an electric cylinder 441, a push plate 442, a guide rod structure 443, a horizontal insert plate structure 444, a guide wheel 445, a push brush 446, a brush connecting plate 448 and a lower dust box 447.
