The invention comprises a plurality of pairs of openable or closable half cylinder bodies 21 to form the material conveying cylinder 2, when the interior needs to be cleaned, most residual materials in the two opened half cylinder bodies 21 can directly slide out, and the two opened half cylinder bodies 21 can leave a large amount of cleaning operation space for the cleaning mechanism 5, specifically, the cleaning part (brush surface structure of a brush) of the cleaning mechanism 5 can be set to be similar to the size of the cylinder body of the material conveying cylinder 2, namely, the area where the cleaning mechanism 5 can clean in place at one time is equal to one cross section of the material conveying cylinder 2.
In order to reduce the friction force during the relative rotation of the half cylinder 21 and the driving shaft 31, the present invention is further provided as follows: the two ends of the driving shaft 31 are respectively sleeved with a bearing 8, and the inner side of each half cylinder 21 is provided with a notch so as to avoid the corresponding bearing 8 when the half cylinders 21 are folded, and the notch is in sealing contact with the corresponding bearing 8 through a rubber pad.
When two half cylinder 21 are closed, the breach is direct to be fixed through rubber pad and bearing 8 joint, avoids drive shaft 31 and half cylinder 21 direct contact to produce the friction, and the elasticity accessible interference fit of rubber pad itself moreover can avoid simultaneously that the through-hole that two breaches formed is too big with the gap between the drive shaft 31 outer wall, and here the outside of bearing 8 also can overlap to establish the rubber material to make the interlock inseparabler.
The invention also provides a specific scheme of the cleaning mechanism 5: the number of the cleaning mechanisms 5 is the same as the logarithm of the half cylinder 21; each sweeping mechanism 5 comprises an inverted U-shaped frame 51 which can be horizontally or longitudinally arranged in a reciprocating sliding manner; long bristles 53 are arranged on the two inner sides of the inverted U-shaped frame 51, and semicircular sponge wipers 52 are arranged on the two outer sides of the inverted U-shaped frame 51; when each pair of half cylinders 21 is opened, the inverted U-shaped frame 51 is sleeved on the packing auger 34, the long bristles 53 are in contact with the surface of the packing auger 34 or the surfaces of the packing auger 34 and the driving shaft 31 respectively, and the semicircular sponge wipers 52 are in contact with the inner walls of the corresponding half cylinders 21.
The specific cleaning principle of the cleaning mechanism 5 is that when the two half cylinders 21 are opened, the inverted U-shaped frame 51 vertically slides downwards, so that the inverted U-shaped frame 51 is sleeved on the auger 34, in the embodiment shown in fig. 1, the long bristles 53 are respectively contacted with the surfaces of the auger 34 and the driving shaft 31, then the two semicircular sponge brushes 52 on two sides can be respectively contacted with the inner wall of the half cylinder 21 by moving the half cylinder 21, and of course, the maximum opening range of the two half cylinders 21 on two sides is just smaller than the integral width of the semicircular sponge brushes 52 on two sides, so that the semicircular sponge brushes 52 can be extruded into the semicircular sponge brushes through elastic deformation.
Then, by slowly rotating the auger 34, the long bristles 53 can clean the surfaces of the auger 34 and the driving shaft 31 relatively uniformly, so that the cleaning mechanism 5 can clean efficiently in units of the cross section of the cleaning feed cylinder 2 at a time; finally, the whole cleaning mechanism 5 is moved slowly along the extending direction of the driving shaft 31, thereby completing the whole cleaning, and in the cleaning process, various cleaning residues generated in the cleaning process can directly fall out of the half cylinder 21 due to the opening process of the half cylinder 21, so that the condition that the cleaning residues remain in the cylinder is avoided.

Further, each half cylinder 21 is provided with a half feed pipe 22 and a half discharge pipe 23 for splicing with the corresponding half cylinder 21.
Preferably, the upper surface of the chassis 13 of the present invention is fixedly mounted with the collecting tank 9.

Further, a sealing groove 24 is formed on the splicing side of one of the half cylinders 21, a sealing strip 25 matched with the sealing groove 24 is fixedly installed on the splicing side of the other of the half cylinders 21, and the sealing groove 24 and the sealing strip 25 extend to the side surfaces of the half feeding pipe 22 and the half discharging pipe 23 on the same side.
Due to the arrangement of the sealing grooves 24 and the sealing strips 25, when the screw feeder is used for conveying materials, the sealing strips 25 fixed on one half cylinder 21 are clamped into the sealing grooves 24 formed on the other half cylinder 21, so that the sealing of the material conveying cylinder 2 is realized, the materials cannot flow out of gaps between the two half cylinders 21, the conveying effect of the screw feeder is ensured, and the sealing grooves 24 and the sealing strips 25 extend to the side surfaces of the half feed pipes 22 and the half discharge pipes 23 on the same side.

Because the cleaning residues fall out from the bottom of the half cylinder 21, the cleaning residues easily slide into the sealing groove 24 along the sealing groove 24, so that the sealing groove 24 is not tightly meshed, the semicircular sponge wiper 52 can be made into a shape suitable for the edge of the half cylinder 21, but the semicircular sponge wiper 52 is difficult to clean the groove, so that the electric push rod II 62 or the guide rod II 63 has a remarkable downward action when the cleaning mechanism 5 works, the elastic extrusion bag 247 is extruded by the extrusion body 248 through the action, the rubber cavity 241 is extruded by gas in the elastic extrusion bag 247, the concave part of the rubber cavity 241 is outwards protruded, and the cleaning of the semicircular sponge wiper 52 is facilitated.
