Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, specifically to a manure removal device for animal husbandry. Background Technology

[0002] In sheep farming, timely cleaning and treatment of sheep manure is crucial for ensuring hygiene in sheep pens and preventing the spread of diseases. Sheep manure is usually semi-solid with a certain viscosity and high initial water content. If it is not effectively separated from its solid state in a timely manner, it will not only cause difficulties in subsequent transportation, storage, and resource utilization, but also easily generate harmful gases such as ammonia and hydrogen sulfide in the sheep pen, affecting the health and growth of sheep.

[0003] Traditional manure removal methods involve collecting feces, urine, and flushing water together, which has significant drawbacks: First, the mixed manure is bulky and heavy, increasing transportation frequency, energy consumption, and costs, and requiring large storage facilities that occupy space; second, the lack of separation promotes microbial fermentation, continuously releasing foul gases that pollute the air, breed mosquitoes and flies that spread diseases, and threaten the environment and biosecurity of livestock farms. Therefore, we propose a manure removal device for livestock farming to solve the above problems. Utility Model Content

[0006] The primary solid-liquid separation mechanism includes a movable filter plate, the outer walls of which are movably connected to a rectangular hole through rectangular grooves; the movable filter plate has several filter holes for preliminary solid-liquid sieving of the feces entering the manure shovel frame; the movable filter plate is equipped with a vibrating element.

[0007] The secondary solid-liquid separation mechanism is located on the left side of the movable filter plate. It includes a separation chamber opened inside the manure shovel frame, and the separation chamber is connected to the manure shovel frame through a feed inlet. The separation chamber is equipped with a rotating shaft driven by a drive component and a feeding screw fixed on the rotating shaft. The bottom of the separation chamber is provided with several filter holes for secondary solid-liquid separation during the screw conveying and extrusion process. The drive component includes a drive motor, and the output end of the drive motor is fixedly connected to one end of the rotating shaft.

[0008] The manure shovel frame has an internal collection chamber for collecting the separated liquid, and an external conveying assembly for transporting the liquid from the collection chamber to the mobile carriage; the end of the separation chamber has a discharge port for discharging solid manure.

[0009] The mobile carriage is equipped with a conveying structure for conveying solid feces from the discharge port to a storage container that is movably connected inside the mobile carriage.

[0010] Furthermore, the vibrating component includes a vibration motor, which is fixedly installed on the lower left end of the movable filter plate to drive it to vibrate the movable filter plate, thereby improving the initial filtration separation.

[0011] Furthermore, a support plate is fixedly installed inside the liquid collection chamber, and several springs are fixedly installed on the surface of the support plate. The top ends of the several springs are fixedly connected to cleaning cylinders, and the top ends of the cleaning cylinders penetrate the interior of the filter hole one.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please see Figures 1-7A manure removal device for livestock farming includes a mobile vehicle 1 and a manure shovel frame 2 fixedly installed on the outer wall of one end of the mobile vehicle 1. The manure shovel frame 2 is equipped with a primary solid-liquid separation mechanism and a secondary solid-liquid separation mechanism. A rectangular hole 21 is opened in the manure shovel frame 2. By integrating the manure shovel frame 2 with the mobile vehicle 1, a mobile working unit is formed, which significantly improves the flexibility and efficiency of manure removal operations. The integration of the two-stage solid-liquid separation mechanism in the manure shovel frame 2 enables continuous grading treatment of manure on-site, realizing source reduction and preliminary resource classification of manure and wastewater. This completely changes the cumbersome traditional model of collecting first and then treating, and greatly improves the efficiency and environmental friendliness of the entire manure removal process.

[0028] The primary solid-liquid separation mechanism includes a movable filter plate 22. The outer walls of both ends of the movable filter plate 22 are movably connected to rectangular holes 21 via rectangular grooves 221. The movable filter plate 22 has several filter holes 222 for preliminary solid-liquid screening of the manure entering the manure shovel frame 2. The movable filter plate 22 is equipped with a vibrating element, including a vibration motor 223. The vibration motor 223 is fixedly installed on the lower left end of the movable filter plate 22 to drive it to vibrate, thereby improving the preliminary filtration and separation. 2. The rectangular groove 221 and the rectangular hole 21 are matched to achieve a movable connection, providing the necessary space for vibration. After the vibration motor 223 is started, it drives the movable filter plate 22 to generate high-frequency micro-amplitude vibration. This vibration can effectively break the compacted state of the fecal material, making it loose, thereby accelerating the separation of liquid components through the filter hole 222. At the same time, the vibration has a self-cleaning effect, which can significantly reduce the phenomenon of wet and sticky feces clogging the filter hole 222, ensuring the continuous smoothness and efficiency of the initial screening, and laying a good foundation for subsequent deep treatment.

[0029] The secondary solid-liquid separation mechanism is located to the left of the movable filter plate 22, including a separation chamber 23 opened inside the manure shovel frame 2. The separation chamber 23 is connected to the manure shovel frame 2 through the feed inlet 210. The separation chamber 23 is equipped with a rotating shaft 231 driven by a drive component and a feeding screw 232 fixed to the rotating shaft 231. Several filter holes 233 are opened at the bottom of the separation chamber 23 for secondary solid-liquid separation during the screw conveying and extrusion process. The drive component includes a drive motor 235, the output end of which is fixedly connected to one end of the rotating shaft 231. The separation mechanism constitutes a deep processing stage for semi-solid feces. The material, after initial separation, moves towards the discharge port 234 under the push of the feeding screw 232. During this process, the screw blades generate continuous squeezing and shearing forces on the material, which can further release and squeeze out the residual liquid encapsulated therein. The squeezed liquid is discharged through the filter hole 233. This integrated "conveying-squeezing" design not only realizes the transfer of materials, but also completes a secondary and more thorough solid-liquid separation during the transfer process, which significantly improves the solid content of solid feces, making it easier for subsequent transportation, storage and utilization.

[0030] The manure shovel frame 2 has a collection chamber 24 for collecting the separated liquid, and a conveying assembly is provided outside the manure shovel frame 2 for conveying the liquid in the collection chamber 24 to the mobile vehicle 1. The end of the separation chamber 23 has a discharge port 234 for discharging solid manure. The design of the liquid collection chamber 24 collects the liquid separated from the first and second stages in a unified manner, realizing centralized management of liquid waste. The conveying assembly realizes the active transfer of the collected manure liquid from the manure shovel frame 2 to the mobile vehicle 1, so that the liquid and solid manure can be collected separately in different containers on the mobile vehicle 1. This "solid-liquid separation" design fundamentally solves the pain points of solid-liquid mixing and difficult subsequent treatment in traditional manure cleaning methods, and provides great convenience for the resource utilization and classified utilization of manure (such as solid composting and liquid biogas slurry).

[0031] The mobile carriage 1 is equipped with a conveying structure 3, which is used to convey solid feces in the discharge port 234 to a storage container that is movably connected inside the mobile carriage 1.

[0032] In this embodiment, the conveying structure 3 serves as the final collection channel for solid feces. It directly and encloses the solid feces after two-stage dehydration treatment from the discharge port 234 of the separation chamber 23 to the storage container on the mobile carriage 1. This design avoids the spillage and secondary pollution of solid feces during transportation, maintaining a clean working environment. At the same time, the use of a movable storage container facilitates quick replacement after full load, ensuring that the device can continuously perform long-term feces cleaning operations, greatly improving the overall operating efficiency.

[0033] Reference Figures 5-7As shown, a support plate 26 is fixedly installed inside the liquid collection chamber 24. Several springs 261 are fixedly installed on the surface of the support plate 26. The top of the several springs 261 is fixedly connected to a cleaning cylinder 262, and the top of the cleaning cylinder 262 penetrates the interior of the filter hole 222. Several guide holes 263 are opened on the support plate 26.

[0034] In this embodiment, a cleaning cylinder 262 supported by a spring 261 is provided. When the vibrating motor 223 drives the movable filter plate 22 to vibrate, it will generate a corresponding up-and-down reciprocating motion. This motion allows the top of the cleaning cylinder 262 to periodically move up and down on the filter hole 222 on the movable filter plate 22, thereby effectively piercing and cleaning fecal fibers or solid particles that may clog the filter hole, significantly reducing the risk of clogging the filter hole 222 and ensuring the continuous and efficient operation of the first-stage solid-liquid separation. The separated liquid flows smoothly into the bottom of the liquid collection chamber 24 through the guide hole 263, realizing the effective separation of the liquid from the vibration cleaning mechanism and avoiding interference.

[0035] Reference Figure 1 and Figure 3 As shown, the conveying assembly includes a water pump 241 fixedly installed on the outer wall of the manure shovel frame 2. The input end of the water pump 241 is connected to the liquid collection chamber 24. The water pump 241 conveys the collected liquid to the fixed storage container on the mobile vehicle 1 through the liquid delivery pipe 242.

[0036] In this embodiment, an efficient liquid transport system is constructed by configuring an independent water pump 241 and a delivery pipe 242. This system can actively and quickly transport the fecal liquid that has been initially and secondarily separated in the liquid collection chamber 24 to the designated fixed storage container on the mobile vehicle 1. This design realizes the immediate transfer and centralized storage of liquid waste, effectively preventing the liquid from accumulating in the manure shovel frame 2 and affecting the subsequent separation effect. It also facilitates the subsequent resource utilization or centralized treatment of the fecal liquid, and improves the continuous operation capability and automation level of the device.

[0037] Reference Figure 2 As shown, the conveying structure 3 includes a connecting pipe 31 connected to the mobile carriage 1. One end of the connecting pipe 31 is fixedly connected to a collection box 32. The collection box 32 is connected to the separation chamber 23 through a discharge port 234. The connecting pipe 31 is fixedly connected to a discharge pipe 33 inside the mobile carriage 1. A one-way valve 34 is movably installed inside the discharge pipe 33. A vacuum pump 35 for providing conveying power is fixedly installed on the mobile carriage 1. The vacuum pump 35 is connected to the connecting pipe 31 located at one end of the discharge pipe 33.

[0038] In this embodiment, the conveying structure 3 adopts the principle of negative pressure pneumatic conveying. The vacuum pump 35 operates, generating negative pressure in the connecting pipe 31 and the collection box 32. This negative pressure draws the solid feces, after being dehydrated by the screw extrusion, out of the discharge port 234 of the separation chamber 23, and sequentially through the collection box 32, the connecting pipe 31, and the discharge pipe 33, finally into the movable storage container in the mobile carriage 1. The one-way valve 34 installed in the discharge pipe 33 can effectively prevent the reverse flow of materials and airflow, ensuring the singleness and reliability of the conveying direction. This conveying method has a compact structure, high conveying efficiency, and can directly deliver solid feces into the storage container over long distances, greatly reducing the intensity of manual labor.

[0039] Reference Figure 1 and Figure 3 As shown, the bottom surface of the manure shovel frame 2 is provided with an inclined manure guiding surface 27.

[0040] In this embodiment, the inclined manure guiding surface 27 gradually decreases from the right end of the manure shovel frame 2 to the left end (i.e., towards the separation chamber 23). This structural design utilizes gravity to allow the semi-solid manure, after initial separation by the movable filter plate 22, to automatically and smoothly slide into the feed inlet 210 of the secondary solid-liquid separation mechanism. This not only effectively promotes the flow of materials and prevents accumulation at the bottom of the manure shovel frame 2, but also reduces the additional pushing power required for the materials, making the entire manure cleaning process smoother and more efficient. It also helps to guide any residual liquid to the collection chamber 24, further improving the solid-liquid separation effect.

[0041] Workflow: By pushing the mobile cart 1, manure enters the manure shovel frame 2 and falls onto the high-frequency vibrating movable filter plate 22 driven by the vibrating motor 223 for primary separation. Liquid and fine particles enter the liquid collection chamber 24 below through the filter holes 222, while vibration effectively prevents the viscous sheep manure from clogging the filter holes. The semi-dry manure, after initial dehydration, moves to the left under the guidance of gravity and the inclined manure guide surface, and enters the secondary separation chamber 23 through the feed inlet 210. Inside the separation chamber 23, the feeding screw driven by the drive motor 235 not only transports the material forward but also, within the confined space... The process involves continuous squeezing and shearing of the feces. During this process, the residual liquid is fully squeezed out and enters the liquid collection chamber 24 through the finer filter holes 233 at the bottom, achieving deep dehydration. Finally, the solid feces that have been squeezed out are discharged from the discharge port 234 at the end. At the same time, the fecal liquid in the liquid collection chamber 24 is directly pumped into the liquid tank of the mobile carriage 1 by the water pump 241 through the infusion pipe 242 for storage. The solid feces discharged from the discharge port 234 are efficiently sucked into the solid feces container of the mobile carriage 1 by the pneumatic conveying structure under the negative pressure generated by the vacuum pump 35.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
