Description

Technical Field

[0001] The utility model relates to the technical field of soil screening machines, in particular to a soil screening machine with a dust-proof function. Background Art

[0002] The soil screening machine is a vibrating screen used to screen soil, including clay soil. It can remove impurities such as stones, gravel, and leaf decay from the soil (including clay soil). It can also classify the soil (including clay soil) to screen out fine soil with smaller particle sizes. For clay soil, the vibration frequency can be increased. Optional models include linear vibrating screens. For particularly large processing volumes, circular vibrating screens can be used.

[0003] Existing soil screening machines are prone to generate dust during use, which has a serious impact on the environment of the workplace and seriously affects the health of on-site workers. When the machine is in use, it is easy to cause dust to fly all over the sky, which will cause great pollution to the indoor environment of the laboratory.

[0004] In order to effectively reduce dust, the soil screening machine must be modified to meet environmental protection requirements; to this end, we designed a soil screening machine with dust-proof function to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a soil screening machine with a dust-proof function to solve the problems raised in the above background technology.

[0010] As a further preferred solution of the present invention: the dust suction nozzle is arranged at an angle, and the inclination direction is toward the bottom of the feed channel, and the lower side wall of the groove is also arranged at an angle.

[0011] As a further preferred solution of the present invention: the top of the material blocking cloth is connected to the upper side wall of the discharge port, and the size of the material blocking cloth is larger than the size of the discharge port.

[0012] As a further preferred solution of the present invention: a material guide inclined plate is provided at the bottom of the right side surface of the U-shaped mounting seat.

DETAILED DESCRIPTION

[0022] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0023] See also Figure 1-5The sieve 15 is provided with a plurality of sieves 17 and a plurality of sieves 18 are provided on the sieve 15 so that the sieve 15 can be separated from the sieve 15 by a plurality of sieves 17. The top of the feeding channel 5 is connected to the feeding hopper 6, and an L-shaped auxiliary frame 7 is symmetrically provided on the front and rear surfaces of the feeding channel 5. The other end of the L-shaped auxiliary frame 7 is connected to the support frame 1. When the vibrator is started and the vibrating plate 9 starts to screen the soil, it will vibrate, thereby driving the dust cover 4 and the feeding channel 8 to vibrate. The soft feeding channel 8 in this device is a bellows, but not limited to a bellows. As long as it has good toughness and a flexible tubular channel, this application uses the design of the bellows to ensure that the vibration of the feeding channel 8 will not affect the normal feeding, and the entire feeding process is in a sealed state, and dust will not occur. A dust collection component is provided in the feeding channel 5, and a water tank 13 is provided at the bottom of the front side of the support frame 1. An L-shaped connecting pipe 16 is provided at the bottom of the right surface of the water tank 13, and the top of the L-shaped connecting pipe 16 is connected to the dust collection component through a connecting pipe.

[0024] The dust collection assembly includes a plurality of dust collection nozzles 21 installed on the surface of the hollow tube 20. A groove 19 is opened in the horizontal direction on the inner front side wall of the feed channel 5. The hollow tube 20 is arranged in the groove 19. The right end of the hollow tube 20 passes through the outside of the feed channel 5 and is connected to the top of the connecting pipe. The plurality of dust collection nozzles 21 are distributed at equal intervals along the length direction of the hollow tube 20. A pump body is provided on the connecting pipe. When in use, the pump body is started to transport gas into the water tank 13, so that negative pressure can be generated near the plurality of dust collection nozzles 21. When the device is in the vibrating screen of soil, the vacuum is generated. During the process, floating tiny particles, i.e. dust, will float upward in the direction of the discharge channel 8. When the dust enters the feed channel 5, it will be sucked in by multiple dust nozzles 21 and enter the water tank 13 along the hollow tube 20, the connecting tube and the L-shaped connecting tube 16. The dust comes into contact with the water and is filtered out. It should be noted that the negative pressure needs to be controlled and the suction force of the dust nozzle 21 should not be too large to prevent the suction of larger particles and blockage of the dust nozzle 21 during the discharge process. The technology here is easy to implement for those skilled in the art, so it will not be elaborated in detail.

[0025] A glass observation port 12 is provided on the front surface of the water tank 13, a tank cover 10 is movably provided on the top of the water tank 13, and an exhaust port 11 is provided on the top of the left surface of the water tank 13; the glass observation port 12 makes it convenient for staff to observe the turbidity of the water inside the water tank 13, so as to remind staff to replace the water in time.

[0026] The dust suction nozzle 21 is set at an angle, and the inclination direction is toward the bottom of the feed channel 5; the lower side wall of the groove 19 is also set at an angle to accommodate the inclined dust suction nozzle 21; the purpose of the inclined setting of the dust suction nozzle 21 is to avoid direct contact between materials, such as fine soil, and the mouth of the dust suction nozzle 21 during the feeding process, effectively prevent the dust suction nozzle 21 from being blocked, and improve the dust suction effect, that is, improve the dust prevention effect of the device.

[0027] The top of the material blocking cloth 17 is connected to the upper side wall of the discharge port 18, and the size of the material blocking cloth 17 is larger than the size of the discharge port 18; the material blocking cloth 17 can buffer the falling process of the discharged large solid objects. The more important role of the material blocking cloth 17 is to suppress dust at the discharge port 18, because the discharge process of large solid objects will also be accompanied by dust, further improving the dust-proof effect of the device.

[0028] A material guide ramp 3 is provided at the bottom of the right side surface of the U-shaped mounting seat 14. The arrangement of the material guide ramp 3 facilitates the smooth downward discharge of materials transported on the conveyor belt 15, thereby improving the convenience of using the device.

[0029] Specifically, during the use of this device, the fine soil sieved by the vibration plate 9 falls onto the conveyor belt 15. Dust is likely to occur in this process, and the windproof and dust-suppressing nets arranged on the front and rear sides of the conveyor belt 15 can effectively reduce this phenomenon. At the same time, the setting of the material blocking cloth 17 at the discharge port 18 also plays a role in dust suppression; and, in the process of vibrating and screening the soil, dust will not occur at the feed hopper 6, because the setting of multiple dust suction nozzles 21 makes the floating dust be sucked into the dust suction nozzle 21 when entering the feed channel 5, and finally enter the water tank 13 for filtration; this device can fully guarantee the dust-proof effect, greatly reduce the dust phenomenon, and ensure the health of the staff in the laboratory and the good environment of the laboratory indoor environment.

[0030] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and utility model concept of the present invention, should be covered by the protection scope of the present invention.
