Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The utility model discloses a dry and wet separator of pig manure as shown in figures 1 to 5, which comprises a bracket 10, a motor 20, a screw 30 and an extrusion part 40. The stand 10 has four legs 11 and two stands 12. The foot 11 constitutes a support surface 13, above which the stand 12 is located. The support surface 13 is further provided with a square frame body having a first mounting surface 14 and a second mounting surface 15, a screen passage 16 is arranged between the first mounting surface 14 and the second mounting surface 15, and a feed hopper 17 is arranged on one side of the screen passage 16 close to the first mounting surface 14. One of the carriages 12 mounts a motor 20, the other carriage 12 mounts a bearing 18, and a screw 30 passes through the bearing 18. An electric motor 20 is fixed to the frame 10, and an output shaft of the electric motor 20 is connected to the coupling 19 via a speed reducer 21. The middle of the screw 30 passes through the screen passage 16, one end of the screw 30 passes through the first mounting surface 14 and is connected to the coupling 19, and the other end of the screw 30 passes through the second mounting surface 15. The motor 20 drives the screw rod 30 to rotate through the coupler 19, wet pig manure enters the screen channel 16 from the feed hopper 17, the screw rod 30 drives the wet pig manure to move leftwards, sewage is extruded from the screen, and dry pig manure is sent out from the right side. The screen passage 16 has criss-

cross reinforcing ribs

22, 23 to avoid being crushed by the pig manure.

The screw 30 is composed of eight sections of blades 31 with gradually reduced intervals, the volume of the pig manure is gradually reduced in the process of the pig manure, and the purpose of squeezing out moisture is achieved. Preferably, the distance between the blades 31 is H1, H2, H3, H4, H5, H6, H7, and H8 in sequence from the side close to the motor 20, wherein the ratio of H1: h2: h3: h4: h5: h6: h7: h8= 8.5: 7.5: 6.5: 6: 5.5: 5: 3.5: 2.5. in this example, H1=17cm, H1=14cm, H1=13cm, H1=12cm, H1=11cm, H1=10cm, H1=7cm, H1=5 cm. Through practical comparison, the screw 30 with the length can improve the extrusion efficiency to the maximum extent.

In the present invention, the pressing portion 40 is composed of a cylinder 41 and a conical head 42. The cylinder 41 is fixed at the rear of the bracket 10, and the output shaft of the cylinder 41 is connected to the conical head 42. The conical head 42 is slidably disposed on the threaded rod 30, and the conical head 42 is kept parallel to the threaded rod 30, thereby improving the rigidity of the system. The conical head 42 extends at least partially into the screen passage 16 and dried pig manure is extruded from the gap between the screen passage 16 and the conical head 42. The air cylinder 41 drives the conical head 42 to extrude the pig manure, so that the separation efficiency can be improved. Specifically, the cylinder 41 is mounted on the second mounting surface 15, and the output shaft of the cylinder 41 is connected to a fixing plate 45, and the fixing plate 45 is connected to the conical head 42 via a plurality of guide rods 46. Guide rods 43 may also be used to maintain the position of conical head 42. When the cylinder 41 retracts, the conical head 42 presses the pig manure to the right. The side of the screen channel 16 close to the second mounting surface 15 is provided with a receiving net 44. Meanwhile, in order to prevent the tail part of the channel from being excessively extruded to cause the dried pig manure to fall into the sewage collecting channel, the material receiving net 44 below the channel can collect part of the dried pig manure. In order to maintain the rigidity of the receiving net, the receiving net 44 can be wrapped by reinforcing

ribs

47 and 48. The reinforcing ribs 47 are connected to the second mounting surface 15.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
