Description

Technical Field

[0001] This utility model relates to the field of breeding equipment, and more specifically to a manure scraping device for pig farms. Background Technology

[0002] Currently available pig farm manure scraping equipment mainly utilizes a small cart that can move back and forth within the manure channel. The two ends of the cart are tied with traction ropes or chains, and an external power unit uses the traction ropes or chains to drive the cart to move within the manure channel. The cart is equipped with scrapers, bottom support wheels, and side support wheels. When the scraper moves, it scrapes the manure in the manure channel into the manure collection tanks at both ends of the manure channel. However, in the above structure, the scraper does not make full contact with the bottom surface and inner wall of the manure channel. When the scraper moves, the manure in the manure channel cannot be completely scraped away, meaning that some manure always remains in the manure channel.

[0003] Therefore, how to provide a pig farm manure scraping device that can overcome the above-mentioned problems is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] This utility model discloses a pig farm manure scraping device. The device features a mounting hole 50 on the main scraper 5, into which a flexible plate 7 is slidably and tightly inserted. The flexible plate 7, relying on its own weight and the combined weight of the mounting block 13, pressure plate 14, and counterweight 15, ensures that its lower long sidewall is in full sliding contact with the bottom surface of the manure channel 1. This results in good manure scraping performance when the main scraper 5 moves, preventing excessive manure residue on the bottom surface of the manure channel 1. Simultaneously, the flexible plate 7 does not scratch the bottom surface of the manure channel 1. While the flexible plate 7 is a wear-prone component, its lower long sidewall will wear down over time. However, because it is slidably arranged within the mounting hole 50, even if the flexible plate 7 wears down, it will still move downwards and maintain full contact with the bottom surface of the manure channel 1.

[0030] By designing the secondary scraper, tension spring 10, and flexible plate 2 11, when the main scraper 5 moves, the flexible plate 2 11 keeps sliding contact with the inner wall of the manure channel 1, thereby ensuring that during the scraping process, a large amount of feces will not leak out from between the main scraper 5 and the inner wall of the manure channel 1. The tension spring 10 can tighten the scraper 1 8 and scraper 2 9 to ensure that the flexible plate 2 11 is always pressed against the inner wall of the manure channel 1.

[0031] By designing support wheel 12, a gap is ensured between the lower long side wall of the main scraper 5 and the bottom surface of the manure channel 1. This serves two purposes: firstly, it facilitates the movement of the main scraper 5 and reduces the resistance formed between the main scraper 5 and the inner wall of the manure channel 1 during movement; secondly, it supports the main scraper 5 and prevents direct contact between the main scraper 5 and the bottom surface of the manure channel 1, thus preventing severe wear on the main scraper 5 or the bottom surface of the manure channel 1.

[0032] By designing the second support wheel 17, while ensuring that the second flexible plate 11 slides in contact with the inner wall of the manure channel 1, the second flexible plate 11 will not be excessively pressed against the inner wall of the manure channel 1, thus preventing the second flexible plate 11 from wearing out too quickly when the main scraper 5 moves. The second support wheel 17 can also play a role in reducing resistance.

[0033] Example

[0034] See appendix Figures 1-6 This is a schematic diagram of the overall and partial structure of one embodiment of the present invention. Specifically, the present invention discloses a pig farm manure scraping device, installed within a rectangular manure channel 1. The manure channel 1 is located on the ground, meaning its bottom surface is below the ground level, allowing manure from the ground to flow into it. Manure collection tanks are located at both ends of the manure channel 1. The scraping device scrapes the manure from the manure channel 1 into the two collection tanks. A power unit is arranged outside the manure channel 1, having two connecting ends with opposite operating directions. These connecting ends can move along the length of the manure channel 1. Specifically, the power unit includes a drive motor 2, a corner wheel 3, and a traction rope 4. 2. Fixed outside the manure channel 1, the drive motor 2 is equipped with a rotating roller for winding the traction rope 4. There are at least four corner wheels 3, all of which are installed on the ground. The center line of the four corner wheels 3 can form a rectangle. One end of the traction rope 4 is tied to one side of the main scraper 5. The other end of the traction rope 4 needs to be tied to the other side of the main scraper 5 after passing around the rotating roller and the four corner wheels 3. The traction rope 4 is wound around the rotating roller multiple times. The manure channel 1 is located between two corner wheels 3. The traction rope 4 is centrally arranged in the manure channel 1 along the width direction of the manure channel 1. When the rotating roller rotates forward and backward, it will drive the two ends of the traction rope 4 to move, thereby driving the main scraper 5 to move back and forth in the manure channel 1.

[0035] The manure scraping device includes:

[0036] The main scraper 5 is a rectangular scraper with a vertically arranged surface. The length of the main scraper 5 is perpendicular to the length of the manure channel 1. The main scraper 5 has vertically arranged mounting holes 50 that penetrate its upper and lower long side walls. The mounting holes 50 are rectangular holes. The length of the long side of the mounting hole 50 is the same as the length of the main scraper 5. The length of the long side of the mounting hole 50 is slightly less than the length of the main scraper 5. Two connecting frames 6 are fixed on both sides of the main scraper 5. Each of the two connecting frames 6 is connected to the two connecting ends of the power device, that is, each of the two connecting frames 6 is tied to the two ends of the traction rope 4.

[0037] Flexible plate 7, a rectangular flexible plate 7, is arranged vertically. The length direction of the flexible plate 7 is the same as that of the main scraper 5. The flexible plate 7 is slidably and tightly embedded in the mounting hole 50. The lower long side wall of the flexible plate 7 slides and abuts against the bottom surface of the manure channel 1. The flexible plate 7 is a rubber plate. The sliding contact between the flexible plate 7 and the ground can avoid direct contact between the main scraper 5 and the bottom surface of the manure channel 1 when the main scraper 5 moves, and prevent the main scraper 5 or the bottom surface of the manure channel 1 from being scratched. At the same time, the lower long side wall of the flexible plate 7 fully contacts the bottom surface of the manure channel 1 to ensure thorough scraping of manure.

[0038] The system includes two auxiliary scrapers with a main scraper 5 positioned between them. Each auxiliary scraper consists of a scraper 8 and a scraper 9, both vertically arranged on the surface of the scraper. One end of each scraper 8 and scraper 9 is hinged to one end of the main scraper 5. Scraper 8 and the main scraper 5 share a hinge axis, and scraper 9 and the main scraper 5 share a hinge axis. The plane defined by hinge axis one and hinge axis two at the same end of the main scraper 5 is perpendicular to the surface of the main scraper 5. Both hinge axis one and hinge axis two are vertically arranged. The main scraper 5 is positioned between the end of scraper 8 away from the main scraper 5 and the end of scraper 9 away from the main scraper 5, meaning that scrapers 8 and 9, which are connected to one end of the main scraper 5, are arranged in a V-shape.

[0039] A tension spring 10 is arranged between scraper 1 8 and scraper 2 9, which are hinged to one end of the main scraper 5. The two ends of the tension spring 10 are respectively connected to scraper 1 8 and scraper 2 9. The tension spring 10 can tighten the scraper 1 8 and scraper 2 9 connected to it, so that scraper 1 8 and scraper 2 9 move towards each other, that is, the end of scraper 1 8 away from the main scraper 5 and the end of scraper 2 9 away from the main scraper 5 approach each other. At this time, it is beneficial for the flexible plate 2 11 to press against the inner wall of the manure channel 1.

[0040] A rectangular flexible plate 11 is fixed on each scraper 8 and each scraper 9. The surface of the flexible plate 11 is arranged vertically, and one vertical sidewall of the flexible plate 11 can slide against the inner sidewall of the manure channel 1. When the main scraper 5 moves, the flexible plate 11 can be pressed tightly against the inner sidewall of the manure channel 1 to prevent a large amount of feces from leaking out between the main scraper 5 and the inner sidewall of the manure channel 1.

[0041] Multiple support wheels 12 are rotatably mounted on both sides of the main scraper 5. The axis of the support wheels 12 is parallel to the length direction of the main scraper 5. The multiple support wheels 12 roll and abut against the bottom surface of the manure channel 1 at the same time. When the support wheels 12 roll and abut against the bottom surface of the manure channel 1, there is a gap between the lower long side wall of the main scraper 5 and the bottom surface of the manure channel 1. The design purpose of the support wheels 12 is twofold: one is to facilitate the movement of the main scraper 5 and reduce the resistance formed between the main scraper 5 and the inner wall of the manure channel 1 when the main scraper 5 moves; the other is to support the main scraper 5 and prevent the main scraper 5 from directly contacting the bottom surface of the manure channel 1, thus preventing serious wear on the main scraper 5 or the bottom surface of the manure channel 1.

[0042] Two support wheels 12 are rotatably mounted on each side of the main scraper 5. The two support wheels 12 mounted on the same side of the main scraper 5 are arranged close to both ends of the main scraper 5. While ensuring stable support for the main scraper 5, the number of support wheels 12 is minimized to reduce costs and minimize obstruction to the scraping of manure by the main scraper 5.

[0043] More specifically, it also includes a mounting block 13, a pressure plate 14, and a counterweight block 15. The length direction of the mounting block 13 is the same as that of the main scraper 5. A mounting groove 130 penetrating both ends of the mounting block 13 is formed on one long side wall. The upper side wall of the main scraper 5 is located in the mounting groove 130, and the two side surfaces of the main scraper 5 are in sliding contact with the two side walls of the mounting groove 130. The length direction of the pressure plate 14 is the same as that of the main scraper 5. The surface of the pressure plate 14 is arranged vertically and is located in the mounting groove. Inside 130, the upper side wall of the pressure plate 14 is fixed to the bottom wall of the mounting groove 130, and the lower side wall of the pressure plate 14 abuts against the upper long side wall of the flexible plate 7; the counterweight block 15 is fixed on the mounting block 13; the above design ensures that the lower long side wall of the flexible plate 7 can fully contact the bottom surface of the manure channel 1, and on the other hand, the flexible plate 7 will wear down over a long period of time, that is, the flexible plate 7 will become shorter along the vertical direction, while the pressure plate 14 always presses down on the flexible plate 7, thereby ensuring that the flexible plate 7 can always be in close contact with the bottom surface of the manure channel 1.

[0044] The length direction of the tension spring 10 is perpendicular to the surface of the main scraper 5. At the same time, multiple tension springs 10 are arranged between the scraper 1 8 and scraper 2 9, which are hinged to one end of the main scraper 5. The multiple tension springs 10 ensure that the flexible plate 2 11 can always be pressed against the inner wall of the manure passage 1.

[0045] More specifically, it also includes a connector 16 and a support wheel 17. A connector 16 is fixed on each scraper 8 and each scraper 9. A support wheel 17 is rotatably mounted on each connector 16. The axis of the support wheel 17 is arranged vertically, and the support wheel 17 can roll against the inner wall of the manure channel 1. This design can limit the movement of the flexible plate 11. While ensuring that the flexible plate 11 slides in contact with the inner wall of the manure channel 1, the flexible plate 11 will not be excessively pressed against the inner wall of the manure channel 1, preventing the flexible plate 11 from wearing too quickly when the main scraper 5 moves. The support wheel 17 can also reduce drag.

[0046] The connecting frame 6 is centrally located between the two ends of the main scraper 5. The connecting frame 6 can slide against the bottom surface of the manure channel 1. When the main scraper 5 moves, the main scraper 5 can maintain its vertical arrangement, ensuring that the main scraper 5 can move back and forth stably in the manure channel 1.

[0047] When using this manure scraper:

[0048] The power unit drives the main scraper 5 to move back and forth along the length of the manure channel 1, and the feces in the manure channel 1 can be scraped by the main scraper 5 to the manure collection tanks at both ends of the manure channel 1.

[0049] Flexible plate 7 and flexible plate 11 are respectively attached to the bottom surface and inner wall of the manure channel 1 to ensure the manure scraping effect. Almost all the manure in the manure channel 1 can be scraped into the manure collection tank.

[0050] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0051] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. 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.
