Description

Cylinder continuous rotation air current dredging type traditional Chinese medicine sieving machine
Technical Field
The invention belongs to the technical field of production of traditional Chinese medicine preparations, and particularly relates to a cylinder continuous rotation airflow dredging type traditional Chinese medicine screening machine.
Background
In the production process of traditional Chinese medicine, the sliced traditional Chinese medicine decoction pieces are sometimes required to be screened, and the traditional Chinese medicine decoction pieces with granularity which does not meet the requirement are screened out and then subjected to secondary crushing treatment so as to enable the sizes of the traditional Chinese medicine decoction pieces to meet the requirement. The traditional Chinese medicine screening is finished by manually screening through a sieve, and is changed into screening through a drum sieve, but the traditional drum sieve needs to manually dredge sieve pores after blockage is generated in the traditional Chinese medicine screening process, so that inconvenience is caused when the sieve pores are dredged.
Disclosure of Invention
The invention provides a cylinder continuous rotation air flow dredging type traditional Chinese medicine screening machine which can be dredged without stopping a screen, and solves the problem of labor waste caused by manual dredging of a cylinder screen in the traditional Chinese medicine production process.
The technical problem is solved by the following technical scheme: a barrel continuous rotation dredging type traditional Chinese medicine screening machine is characterized by comprising a rack, a barrel and a push rod, wherein a driving rotating shaft which is obliquely arranged is rotatably connected to the rack, the barrel is coaxially sleeved on the driving rotating shaft and is fixed together with the driving rotating shaft, the barrel is circular, a plurality of rows of sieve mesh rows which are distributed along the axial direction of the barrel are arranged on the circumferential surface of the barrel, each row of sieve mesh rows is provided with a plurality of sieve meshes which are distributed along the circumferential direction of the barrel, the circumferential surface of the barrel is a smooth surface, the push rod extends from one end to the other end of the barrel, the push rod is used for pushing the part of traditional Chinese medicine decoction pieces which extend out of the sieve meshes and are toppled towards the front of the rotation direction of the barrel and extend out of the sieve meshes towards the rear of the rotation direction of the barrel, an end plate which is positioned at the rear end of the push rod along the rotation direction of the barrel is arranged at one end of the push rod, and a cloth air cavity is arranged in the end plate, the side that the push rod is located barrel rotation direction rear end is the plane, the gas distribution chamber is equipped with a plurality of holes of blowing that distribute along the push rod extending direction, the hole of blowing is located the end plate on the surface towards the barrel side, the opening direction of the hole of blowing is on a parallel with the side that the push rod is located barrel rotation direction rear end, the barrel rotates the sieve mesh and when the edge of barrel rotation direction front end was located the plane that the push rod is located barrel rotation direction rear end side place, the sieve mesh that the edge was located the plane that the side of barrel rotation direction rear end was located on was located with the hole of blowing aligns one-to-one, the hole of blowing with sieve mesh row one-to-one aligns. When the sieve is used, the traditional Chinese medicine decoction pieces are poured into the barrel from the high end of the barrel, the barrel rotates under the driving of the driving rotating shaft, the traditional Chinese medicine decoction pieces move towards the low end of the barrel while rotating along with the barrel in the barrel, the traditional Chinese medicine decoction pieces are sieved in the process, the thick traditional Chinese medicine decoction pieces fall out from the low end of the barrel, and the thin traditional Chinese medicine decoction pieces fall out from the sieve pores. The wind that the continuous pivoted in-process blowhole of barrel blew off will block up the herbal pieces-to-be-prepared for each other in the sieve mesh and blow the effect that plays mediation sieve mesh in the barrel, the part that stretches out the sieve mesh that will stretch out the herbal pieces-to-be-prepared for each other that the mesh part topples over towards barrel direction of rotation the place ahead through the push rod pushes away towards the rear of barrel direction of rotation, thereby it is just right with the sieve mesh to stretch out the herbal pieces-to-be-prepared for each other that the mesh part topples over towards barrel direction of rotation the place ahead to stretch out the mesh part when making the push rod arrive at the sieve mesh edge, make the wind that blows off can push back the herbal pieces-to-be-prepared for each other that stretches out the mesh part that will block up in the sieve mesh more reliably topples over towards barrel direction of rotation the place ahead, thereby play the effect that improves the mediation reliability.
