Description

Technical Field

[0001] This utility model relates to the field of manure conveying technology, specifically a spiral conveying device for poultry and livestock manure. Background Technology

[0002] In livestock farming, the cleaning and transportation of poultry and livestock manure is a crucial aspect of ensuring farm hygiene. Traditional methods mainly rely on manual labor or scraper conveying, which suffers from low efficiency, high energy consumption, and poor sealing leading to odor diffusion. The core spiral blade structure, material, and sealing technology of this method are adapted to the environment of transporting manure.

[0003] However, some existing screw conveyor devices have a fixed discharge port structure, and the opening cannot be vertically downward. This makes it easy for feces to clog the discharge port, resulting in low conveying efficiency. Furthermore, the clogged feces will increase the resistance of the screw blade rotation, which will cause the motor output resistance to be too high, leading to motor overload and affecting working efficiency.

[0004] Furthermore, there is no obstruction structure at the discharge port. When the transported feces are relatively loose, the feces fall quickly under the power and gravity provided by the spiral blades, and are prone to splashing at the bottom of the discharge port. This causes the feces to splash onto the outside of the transport vehicle and onto the workers, which not only wastes feces but also pollutes the air. Utility Model Content

[0005] The purpose of this utility model is to provide a screw conveyor for livestock manure to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spiral conveyor for livestock manure, comprising a support frame and a conveying pipe fixedly connected therein, and further comprising: A feed hopper is installed at the top of the conveying pipeline. A main shaft is rotatably connected to the inner cavity of the feed hopper. Spiral blades are fixedly connected to the surface of the main shaft. A crossbar is installed on the surface of the support. A motor is fixedly connected to one end of the crossbar. A discharge hole is opened at the bottom of one end of the conveying pipe. A feeding mechanism is installed on the surface of the discharge hole, and an anti-splashing mechanism is installed on the surface of the feeding mechanism.

[0007] Preferably, the feeding mechanism includes a flexible hose fixedly connected to the surface of the discharge hole, a connecting rod fixedly connected to the top of the crossbar, a feeding pipe rotatably connected to one end of the connecting rod, and a counterweight fixedly connected to the bottom of the feeding pipe.

[0008] Preferably, the anti-splash mechanism includes an annular baffle slidably connected to the surface of the discharge pipe, a rotating base fixedly connected to the top of the annular baffle, a gripping rod rotatably connected to the surface of the rotating base, and a return spring fixedly connected to the surface of the gripping rod.

[0009] Preferably, the hose is deformable and its inner wall is provided with a smooth and flat plastic film, and the length of the hose is longer than the height of the discharge pipe.

[0010] Preferably, there are two annular baffles, rotating bases, and gripping rods, which are distributed symmetrically in opposite directions on the surface of the annular baffles.

[0011] Preferably, the annular baffle has an inverted U-shaped structure design.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the structural design of the feeding mechanism, makes the discharge port vertically downward. This design allows the feces to fall at a faster speed, effectively avoiding the problem of feces accumulating at the outlet and causing blockage. This design not only improves the working efficiency of the entire device, but also greatly reduces the output resistance of the motor, effectively extending the service life of the motor. Furthermore, with the help of the anti-splash mechanism, the device can block the outlet of the feces when transporting relatively thin feces, effectively preventing the feces from splashing in the air, thereby preventing the feces from splashing outside the transport vehicle and onto the staff, and avoiding waste of feces. This solves the problem that existing devices are prone to clogging and waste feces during use. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 As shown, a spiral conveyor for livestock manure includes two supports 1, which are installed on the ground to support the entire conveyor.

[0017] The inner wall of the support 1 is fixedly connected to the conveying pipe 2. The top of the conveying pipe 2 is provided with a feeding hopper 3. The feeding hopper 3 is designed with an open structure to guide the feces. The inner cavity of the feeding hopper 3 is rotatably connected to the main shaft 4. The surface of the main shaft 4 is fixedly connected to the spiral blades 5. By rotating the main shaft 4, the spiral blades 5 are driven to rotate, thereby driving the feces inside the conveying pipe 2 to move forward to achieve the conveying effect.

[0018] The surface of the support 1 is equipped with crossbars 6, and there are several crossbars 6. One end of the crossbar 6 is fixedly connected to a motor 7. The output shaft of the motor 7 is fixedly connected to the main shaft 4. Through the cooperation of the support 1 and the crossbars 6, the motor 7 can be supported and fixed. The motor 7 drives the main shaft 4 to rotate, which in turn drives the spiral blades 5 to rotate, thereby transporting the feces.

[0019] The bottom of one end of the conveying pipe 2 is provided with a discharge hole 8 for discharging feces. A feeding mechanism 9 is installed on the surface of the discharge hole 8. The feeding mechanism 9 includes a flexible hose 91 fixedly connected to the surface of the discharge hole 8. The flexible hose 91 has deformable characteristics and its inner wall is provided with a smooth and flat plastic film. A connecting rod 92 is fixedly connected to the top of the crossbar 6. There are two connecting rods 92. One end of the connecting rod 92 is rotatably connected to the feeding pipe 93. A counterweight 94 is fixedly connected to the bottom of the feeding pipe 93.

[0020] When the feces are carried above the discharge hole 8 by the spiral blade 5, they fall onto the transport hopper below through the discharge pipe 93 under the action of gravity. With the cooperation of the connecting rod 92 and the discharge pipe 93, the opening of the discharge pipe 93 is always vertically downward, and the counterweight 94 on the surface of the discharge pipe 93 makes the mechanism heavier, thereby preventing the discharge mechanism 9 from being disturbed by external factors such as wind, thus preventing the feces from scattering in the air. Due to the deformation characteristics of the hose 91, the direction of the discharge pipe 93 is not affected by the tilt angle of the conveying pipe 2.

[0021] It should be noted that the length of the hose 91 is longer than the height of the discharge pipe 93, in order to prevent the discharge pipe 93 from slipping off the surface of the hose 91 during operation, thereby preventing sewage leakage.

[0022] The surface of the feeding mechanism 9 is equipped with an anti-splash mechanism 10. The anti-splash mechanism 10 includes an annular baffle 101 that is slidably connected to the surface of the feeding pipe 93. A rotating base 102 is fixedly connected to the top of the annular baffle 101. A gripping rod 103 is rotatably connected to the surface of the rotating base 102. The top of the gripping rod 103 is designed with an arc shape. A return spring 104 is fixedly connected to the surface of the gripping rod 103. There are several return springs 104.

[0023] Lifting the grab bar 103 releases the limiting effect of the connecting rod 92 on the annular baffle 101, allowing the annular baffle 101 to slide along the surface of the discharge pipe 93. When the annular baffle 101 slides to the bottom, it can block the relatively loose feces, preventing it from splashing from the bottom of the discharge pipe 93 onto the outside of the transport truck bed and onto the workers, thus avoiding waste of feces.

[0024] When the transported feces are relatively dry, slide the annular baffle 101 to the top and hang the annular baffle 101 on the surface of the connecting rod 92. Under the action of the return spring 104, the grab rod 103 can be limited to prevent the grab rod 103 from sliding off the surface of the connecting rod 92 during the swing of the discharge pipe 93.

[0025] It should be noted that there are two annular baffles 101, rotating bases 102, and gripping rods 103, which are distributed symmetrically in opposite directions on the surface of the annular baffles 101. The annular baffles 101 have an inverted U-shaped structure design.

[0026] It is worth noting that the technical features such as the motor 7 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, control method and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0027] Working principle: First, adjust the height of the support 1 and the inclination angle of the conveying pipe 2 according to the height of the transport vehicle. Then, depending on the dryness of the feces, decide whether to move the anti-splash mechanism 10. If the feces are relatively dry, there is no need to move the anti-splash mechanism 10. Then, under the action of gravity, the weight of the discharge pipe 93 and the counterweight 94 drives it to rotate downwards until it is vertical. Then, the feces are poured from the feed hopper 3 into the interior of the conveying pipe 2. Next, start the motor 7 to drive the main shaft 4 and the spiral blade 5 to rotate, thus completing the transportation of the feces. If the feces are relatively dry... When the flow is thin, to prevent the feces from splashing out of the transport vehicle and onto the workers at the outlet, the grab bar 103 needs to be raised so that it is detached from the surface of the connecting rod 92, thereby releasing the restriction of the connecting rod 92 on the annular baffle 101. Then, in the unrestricted state, the annular baffle 101 slides along the surface of the discharge pipe 93 to the bottom. Under the structure of the annular baffle 101, the splashed feces can be blocked to prevent them from splashing in the air. Finally, the motor 7 is started to drive the main shaft 4 and the spiral blades 5 to transport the feces, completing the transportation work.
