Technical Field

[0001] This utility model relates to the technical field of manure drying devices, specifically a livestock and poultry manure drying device. Background Technology

[0002] With the rapid development of livestock and poultry farming and the rise of large-scale farming, while people's material living requirements have been met, the problem of livestock and poultry manure has also arisen. In order to utilize the manure for fertilizer purposes, it is necessary to dry it using drying equipment to facilitate subsequent transportation and fertilizer preparation.

[0003] Patent document CN215638636U discloses a livestock and poultry manure drying device. This device includes a drying chamber, a feeding hopper, a blower, a first conveyor belt, a second conveyor belt, and a hot air unit. The drying chamber has a discharge port at its bottom, and the feeding hopper is fixedly installed at the top of the drying chamber. The blower is fixedly installed at the top of the drying chamber and is connected to the interior of the drying chamber. Both the first and second conveyor belts are installed inside the drying chamber, with the first conveyor belt positioned above the second conveyor belt. A first material feeding assembly and a second material feeding assembly are arranged inside the drying chamber, with the first material feeding assembly positioned above the first conveyor belt and the second material feeding assembly positioned above the second conveyor belt. The hot air unit is installed at the bottom of the drying chamber and is connected to the interior of the drying chamber. This device can reduce the impact of the external environment on the drying quality of the material, and it can improve the uniformity of contact between the material and the hot air, thereby shortening the drying time and improving the drying efficiency.

[0004] The above solution lacks a mechanism for evenly spreading the feces during actual use, causing the feces falling from the discharge port to accumulate on the surface of the conveyor belt. This accumulation of feces affects the drying effect of the subsequent hot air blower, resulting in insufficient drying of the accumulated feces inside. Utility Model Content

[0005] This utility model discloses a livestock and poultry manure drying device, which aims to solve the technical problems of uneven and insufficient drying in existing manure drying devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A livestock and poultry manure drying device includes a mounting base, a drying chamber inside the mounting base, a conveyor belt body installed inside the drying chamber, a plurality of first hot air blowers arranged in an equidistant array on the back of the mounting base, and the air outlets of the plurality of first hot air blowers communicating with the interior of the drying chamber, a discharge port embedded on the lower surface of the mounting base, a material box fixedly installed on the upper part of the mounting base by a bracket, a first discharge port embedded on the lower surface of the material box, and a material spreading mechanism provided between the material box and the mounting base.

[0008] The material feeding mechanism includes a mounting groove on the upper surface of the mounting base, a material conveying pipe inside the mounting groove, a reciprocating screw rotatably connected to the front wall and the rear wall of the mounting groove, a first motor fixedly mounted on the front of the mounting base, the output shaft of the first motor extending into the mounting groove and fixedly connected to the front end of the reciprocating screw, a threaded slot adapted to the reciprocating screw on the surface of the material conveying pipe, the material conveying pipe being threadedly connected to the surface of the reciprocating screw through the threaded slot, a feed inlet corresponding to the position of the first discharge port embedded on the upper surface of the material conveying pipe, a through-hole extending into the drying chamber on the inner bottom wall on the left side of the mounting groove, and a second discharge port extending into the drying chamber embedded through the through-hole on the lower surface of the left end of the material conveying pipe.

[0009] In a preferred embodiment, a guide slider is provided at the left end of the conveying pipe, and a guide groove that slides with the guide slider is provided on the left inner wall of the mounting groove.

[0010] By setting a guide slider, the material conveying pipe can reciprocate back and forth inside the mounting groove under the guidance of the guide slider.

[0011] In a preferred embodiment, the cavity inside the conveying pipe is inclined.

[0012] The inclined design of the conveying pipe cavity facilitates the flow of manure within the pipe.

[0013] In a preferred embodiment, a second motor is embedded at the right end of the conveying pipe, and the output shaft of the second motor extends into the interior of the conveying pipe and is fixedly connected to an auger blade.

[0014] The installation of a second motor and auger blades enables the smooth and efficient transport of manure through the conveying pipeline.

[0015] In a preferred embodiment, a rectangular ventilation cavity is provided inside the housing of the feed inlet, and an air outlet is provided inside the rectangular ventilation cavity extending into the feed inlet. A second hot air blower is fixedly installed on the upper surface of the conveying pipe, and the air outlet of the second hot air blower is connected to the interior of the rectangular ventilation cavity.

[0016] The feces in the feed inlet can be initially dried by the setting of a second hot air fan and air outlet.

[0017] In a preferred embodiment, the number of air outlets is several, and the several air outlets are equidistantly arrayed on the inner wall of the rectangular ventilation cavity.

[0018] In a preferred embodiment, four support legs arranged in a rectangular array are fixedly mounted on the lower surface of the mounting base.

[0019] As can be seen from the above, the livestock and poultry manure drying device provided by this utility model has the following technical effects.

[0020] Firstly, under the action of the first motor and the second motor, the operation of the first motor drives the reciprocating screw to rotate. Under the guidance of the guide slider, the conveying pipe moves back and forth in the mounting groove through the rotation of the reciprocating screw. The back and forth movement of the conveying pipe can spread the feces evenly on the surface of the conveyor belt body through the second discharge port, avoiding uneven or insufficient drying due to the large accumulation of feces.

[0021] Secondly, the operation of the second motor can drive the auger blades to rotate. The rotation of the auger blades can make the manure flow more smoothly and efficiently in the conveying pipe. At the same time, the operation of the second hot air blower blows hot air into the rectangular ventilation cavity. The hot air in the rectangular ventilation cavity is then blown into the feed inlet through several air outlets, which can preliminarily dry the manure inside, remove a certain amount of moisture from the manure, and make the subsequent flow of manure smoother.
