[0011] Preferably, the hot air pipe is externally connected to a heating and air supply device.

[0012] (III) Beneficial effects

[0013] The utility model provides a grain drying and cleaning machine. It has the following beneficial effects:

[0014] (1) The grain is first dried by a drying mechanism, which can remove the moisture contained in the impurities while drying the grain, thus preventing the impurities from adhering to the outer wall of the grain or clogging the mesh.

[0015] (2) The grains enter the outer shell through the feed pipe, and the falling grains contact the vibration plate. The vibration generated by the vibration plate causes the grains to continuously jump up and fall down when contacting the vibration plate, thereby increasing the retention time of the grains in the outer shell. At the same time, the jumping drying method leaves no dead corners during drying. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-2 As shown, the grain drying and cleaning integrated machine of this embodiment includes a vibrating screen 1 and a drying mechanism 2, and the drying mechanism 2 is fixedly installed above the vibrating screen 1 through a fixed plate. The grain is first dried by the drying mechanism 2 and then screened by the vibrating screen 1. The drying mechanism 2 includes a shell 201, a feed pipe 202, a hot air pipe 203 and an air outlet 204. The inner wall of the shell 201 is alternately provided with a plurality of vibration plates 3. The vibration plate 3 is located at one end of the inner cavity of the shell 201 lower than the other end. The vibration plate 3 is rotatably installed on the shell 201. A spring 4 is provided between the lower part of the vibration plate 3 and the shell 201. When the grain entering the shell 201 contacts the vibration plate 3, it keeps jumping up and down, thereby increasing the drying time of the grain. A connecting rod 5 is fixedly connected to the end of the vibration plate 3 away from the inner cavity of the shell 201. A through slot 6 adapted to the connecting rod 5 is provided on the shell 201. The vibration motor 8 drives the fixed rod 7 and the connecting rod 5 to reciprocate up and down in the through slot 6. A fixing rod 7 is fixedly arranged at one end of the connecting rod 5 outside the housing 201, and a vibration motor 8 is fixedly installed on the fixing rod 7. The vibration motor 8 drives the vibration plate 3 to reciprocate up and down through the fixing rod 7.

[0021] Furthermore, two vibration motors 8 are disposed on the left and right sides of the housing 201 , and the vibration plates 3 on the same side share the vibration motor 8 on the same side.

[0022] Furthermore, the hot air pipe 203 is externally connected to a heating and air supplying device. The heating and air supplying device provides hot air, which is supplied to the housing 201 through the hot air pipe 203 to dry the grain.

[0023] Working principle: Grains are transported into the housing 201 through the feed pipe 202, and the vibration motor 8 drives the vibration plate 3 to vibrate up and down through the fixed rod 7. After the grains enter the housing 1, the falling grains keep jumping up and falling when they touch the vibration plate 3. The external heating and air supply device provides hot air, and the hot air is supplied to the housing 201 through the hot air pipe 203 to dry the grains from bottom to top. The dried grains and impurities fall on the vibration screen 1 and are screened by the vibration screen 1 to screen out the impurities mixed in the grains.
