Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a device for weighing the weight of farmed pigs and its method of use. Background Technology

[0002] Aquaculture refers to the production activities of cultivating and reproducing plants and animals through artificial intervention, encompassing livestock, poultry, aquaculture, and special breeding. Qin Mu once described the breeding process of chrysanthemums and goldfish, while Xu Chi mentioned aquaculture scenarios. Modern aquaculture technology includes the formulation of feeding standards and the application of fermentation beds.

[0003] In the livestock industry, the most common type of livestock farming is pig farming. In order to understand the physical condition of the pigs, such as whether they have reached the breeding weight standard, a weighing device is needed to weigh the pigs. A common weighing device consists of a base with a weighing sensor and a fence.

[0004] To prevent pigs from escaping, typical enclosure structures consist of four fences. However, these fences are usually fixed to the base and cannot be moved or adjusted. When dealing with pigs of different sizes, a larger enclosure provides them with more room to move around, making it difficult to position them. As the pigs run around, the weighing data may be inaccurate. Therefore, we propose a pig weight weighing device and its usage method. Summary of the Invention

[0045] Secondly, the present invention provides a method for using a pig weight weighing device, which is implemented as described above. The specific steps of the method are as follows:

[0046] Step 1: Move the handle down so that the handle moves the movable rod down until the limiting block comes out of the limiting groove. Then rotate the handle 90 degrees and move the handle up so that the limiting block slides out of the through groove. Then flip the handle outward 180 degrees to unfold the handle assembly.

[0047] Step 2: Rotate the handle to make the handle assembly drive the threaded rod to rotate, thereby making the moving block move horizontally, which in turn moves the connecting assembly and its moving frame, and makes the moving auxiliary assembly move along the flat plate and the slope plate. At the same time, the insert gradually moves down along the slot, thereby reducing the internal space of the fence assembly.

[0048] Step 3: By rotating the handle in the opposite direction, the moving block moves in the opposite direction, while the insert gradually moves upward along the slot, thereby moving the moving frame back and expanding the internal space of the fence assembly.

[0049] The technical effects and advantages of this invention are as follows:

[0050] 1. This invention uses a handle assembly to drive a drive assembly, which in turn moves a connecting assembly horizontally. Simultaneously, a movement auxiliary assembly assists the movement of both sides of the fence assembly. The fence assembly also moves horizontally and downwards along the base plate assembly. This movement of both sides of the fence assembly alters the internal enclosure space, thereby providing different restrictions for pigs of different sizes. This prevents pigs from running around during weighing, which could lead to inaccurate weighing. The design allows for adjustment of the fence assembly according to the pig's size, facilitating better restriction of the pig and preventing it from running around and affecting the final weighing result.

[0051] 2. The present invention moves the handle so that the limiting block passes through the through groove, and the handle squeezes the movable sleeve, causing the actuating spring to deform. Then, the handle is rotated 90 degrees, and the slight recovery deformation of the actuating spring causes the limiting block to be inserted into the limiting groove, thereby retracting the handle assembly.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] This invention provides, for example Figures 1-6 The image shows a device for weighing the weight of farmed pigs.

[0062] Example 1: Includes a base plate assembly 2, a fence assembly 1 connected to the top of the base plate assembly 2, a movable base connected to the bottom of the base plate assembly 2, a weighing sensor 8 disposed between the movable base and the base plate assembly 2, a drive assembly 5 disposed in the middle of the movable base, and the drive assembly 5 is used to drive the fence assembly 1 to move on both sides, a handle assembly 9 disposed at one end of the drive assembly 5, a connecting assembly 6 disposed between the drive assembly 5 and the fence assembly 1, and a movement auxiliary assembly 7 disposed between the fence assembly 1 and the base plate assembly 2; the drive assembly 1 is driven by the handle assembly 9. When component 5 moves, the drive component 5 moves the connecting component 6 horizontally. At the same time, the moving auxiliary component 7 assists the movement of both sides of the fence component 1. Simultaneously, the fence component 1 will move horizontally and downward along the base plate component 2. By moving the fence component 1 on both sides, the fence space inside the entire fence component 1 is changed, thereby restricting pigs of different sizes differently. This prevents the pigs from running back and forth during the weighing process, which would lead to inaccurate final weighing results. This design can adjust the fence component 1 according to the size of the pig, thus making it easier to restrict the pigs and prevent them from running back and forth, which would affect the final weighing results.

[0063] Furthermore, the drive assembly 5 includes side plates 501, and both sides of the movable base are fixedly connected to the side plates 501. The drive threaded rod 502 is rotatably disposed between the two side plates 501, and the outer surface of the drive threaded rod 502 is threadedly connected to the moving block 503. The handle assembly 9 drives the drive threaded rod 502 to rotate along the side plates 501. The moving block 503 is threaded with the drive threaded rod 502, so that the drive threaded rod 502 drives the moving block 503 to move. The drive threaded rod 502 is a double-ended threaded rod. For example, when the drive threaded rod 502 rotates forward, it drives the two moving blocks 503 on the drive threaded rod 502 to move closer to each other, so that the internal fence space of the fence assembly 1 becomes smaller. When the drive threaded rod 502 rotates in reverse, it drives the two moving blocks 503 to move away from each other, so that the internal fence space of the fence assembly 1 becomes larger. This makes it easier to restrict the pigs of different sizes and prevent them from running away.

[0064] Furthermore, the handle assembly 9 includes a fixing block 901, which is fixedly connected to the end of the drive threaded rod 502. A through hole 908 is formed in the middle of the fixing block 901, and through grooves 909 are formed on both sides of the through hole 908. Limiting grooves 910 are formed on both sides of the bottom of the through hole 908. The handle rod 902 is hinged to the outside of the fixing block 901. A protrusion 903 is fixedly connected to one end of the handle rod 902. An elastic component 904 is inserted into the middle of the protrusion 903. A movable rod 905 is inserted into the interior of the elastic component 904. A grip 906 is fixedly connected to one end of the movable rod 905, and limiting blocks 907 are fixedly connected to both sides of the other end of the movable rod 905. The elastic component 904 includes a movable sleeve 9041 inserted into the protrusion 903 and a pushing spring 9042 sleeved on the outside of the movable sleeve 9041. The movable rod 905 is inserted into the interior of the movable sleeve 9041. When the handle assembly needs to be used... At 9 o'clock, by moving the handle 906 downward, the movable rod 905 and the limiting block 907 move downward until the limiting block 907 separates from the limiting groove 910. Then, rotate the handle 906 ninety degrees so that the limiting block 907 aligns with the through groove 909. Then, move the handle 906 upward until the limiting block 907 abuts against the movable sleeve 9041. Then, flip the handle rod 902 outward one hundred and eighty degrees. At this point, the handle assembly 9 is unfolded, and then the handle can be rotated. Move 906 to rotate the fixed block 901 and its drive threaded rod 502. When not in use, move the handle 906 so that the limiting block 907 passes through the through groove 909 and the handle 906 presses the movable sleeve 9041, causing the push spring 9042 to deform. Then rotate the handle 906 ninety degrees and use the slight recovery deformation of the push spring 9042 to make the limiting block 907 snap into the limiting groove 910, thereby retracting the handle assembly 9.

[0065] Furthermore, the base plate assembly 2 includes a support plate 201, which is located above the movable base. A flip block 202 is hinged to one side of the support plate 201, and a flip plate 203 is hinged to one side of the flip block 202. Two sets of side sliding grooves 204 are provided on both sides of the support plate 201, and two sets of central sliding grooves 205 are provided in the middle of the support plate 201. The connecting component 6 mainly moves along the central sliding grooves 205, and the moving auxiliary component 7 moves along the side sliding grooves 204. The central sliding grooves 205 are located within... The width of the central slide and the internal width of the side slide 204 can be set to be relatively narrow to prevent the pig's feet from getting stuck in the central slide 205 or the side slide 204. When weighing, the flip plate 203 can be rotated in advance so that the flip plate 203 rotates along the flip block 202 until one side of the flip plate 203 is close to the ground and tilted, so that the pig can easily enter the fence assembly 1 along the flip plate 203. The movable sides of the fence assembly 1 mainly move along the bearing plate 201.

[0066] Furthermore, the bearing plate 201 includes two flat plates 2011, each with a slope plate 2012 fixedly connected to one side. A sunken plate 2013 is fixedly connected between the two slope plates 2012. When the drive threaded rod 502 rotates forward, it drives the movable sides of the connecting component 6 and its fence component 1 to move. The movable sides of the fence component 1 will first move horizontally along the flat plate 2011 and move closer to each other, thereby reducing the internal lateral space of the fence component 1, which facilitates the restriction of pigs of different sizes. Then, they will gradually move downward along the slope plate 2012, thereby simultaneously reducing the lateral and longitudinal space of the fence component 1, thereby further restricting pigs of different sizes and preventing them from running back and forth, which would affect the weighing data. Later, the drive threaded rod 502 can be reversed to make the movable sides of the fence component 1 move away from each other, thereby expanding the internal fence space of the fence component 1.

[0067] Furthermore, the fence assembly 1 includes a fixed railing 101, which is fixedly connected to both sides of the top of the support plate 201. Movable frames 102 are located on the other two sides of the top of the support plate 201. Opening railings 103 are hinged inside the movable frames 102, and pins 105 are provided on one side of the opening railing 103 and one side of the movable frame 102. A top railing 104 is fixedly connected to the top of the movable frame 102. The movable sides of the fence assembly 1 are the movable frames 102. When the drive threaded rod 502 moves the moving block 503, it moves the connecting assembly 6, thereby moving the movable frames 102 and their opening railings 103. For example, when the drive threaded rod 502 rotates clockwise, it moves both movable frames 102. 02 First, the moving frame 102 moves horizontally along the flat plate 2011 and moves closer to each other, thereby cooperating with the opening and closing fence 103 to reduce the horizontal space of the fence assembly 1. When the moving frame 102 moves down along the slope plate 2012, it cooperates with the opening and closing fence 103 and the top fence 104 to reduce the horizontal and vertical space inside the fence assembly 1. Later, the latch 105 can be moved to open the opening and closing fence 103, thereby driving the pigs into the fence assembly 1. Then, the opening and closing fence 103 is closed, thereby using the weighing sensor 8 to weigh the pigs. The weighing sensor 8 transmits the weighing data to the corresponding display device for display. The display device and the weighing sensor 8 are existing technologies and will not be described in detail here.

[0068] Furthermore, the connecting component 6 includes a fixing piece 601, which is slidably disposed in the middle of the central groove 205. The top of the fixing piece 601 is fixedly connected to the bottom of the moving frame 102. An insert piece 602 is fixedly connected to the bottom of the fixing piece 601, and the outer contour of the insert piece 602 is U-shaped. Slots 603 are opened on both sides of the moving block 503, and the insert piece 602 is inserted into the slot 603. When the moving frame 102 moves along the slope plate 2012, the insert piece 602 will gradually penetrate into the slot 603, thereby realizing the purpose of the moving frame 102 moving down along the slope plate 2012. Conversely, when the moving frame 102 moves up, the insert piece 602 moves up along the slot 603. The thickness of the fixing piece 601 is adapted to the width of the central groove 205.

[0069] Furthermore, the moving auxiliary component 7 includes a slider 701, which is fixedly connected to both sides of the bottom of the moving frame 102. Each slider 701 has two rotating shafts 702 on one side, and the two rotating shafts 702 are arranged vertically. The traveling wheel 703 is rotatably connected to the outside of the rotating shafts 702. When the moving frame 102 moves along the support plate 201, the slider 701 moves along the side sliding groove 204, and the traveling wheel 703 rolls along the support plate 201, thereby facilitating the smooth movement of the moving frame 102 along the flat plate 2011 and the slope plate 2012.

[0070] Example 2: Example 2 further discloses, based on Example 1, that the movable base includes a bottom frame 3 located at the bottom of the support plate 201 and a plurality of movable wheels 4 fixedly installed at the bottom of the bottom frame 3; the entire weighing equipment is moved by the movable wheels 4, for example, the user can push the fence assembly 1, thereby using the movable wheels 4 to roll on the ground, thereby realizing the movement of the entire weighing equipment.

[0071] A method for using a pig weight weighing device, wherein the specific steps for using the aforementioned pig weight weighing device are as follows:

[0072] Step 1: By moving the handle 906 downward, the handle 906 drives the movable rod 905 downward until the limiting block 907 goes out of the limiting groove 910. Then rotate the handle 906 ninety degrees, and then move the handle 906 upward, so that the limiting block 907 slides out of the through groove 909. Then flip the handle rod 902 outward one hundred and eighty degrees to unfold the handle assembly 9.

[0073] Step 2: Rotate the handle 906, causing the handle assembly 9 to drive the drive threaded rod 502 to rotate, thereby causing the moving block 503 to move horizontally, thus causing the connecting assembly 6 and its moving frame 102 to move, and causing the moving auxiliary assembly 7 to move along the flat plate 2011 and the slope plate 2012. At the same time, the insert 602 gradually moves down along the slot 603, thereby reducing the internal space of the fence assembly 1.

[0074] Step 3: By rotating the handle 906 in the opposite direction, the moving block 503 moves in the opposite direction, while the insert 602 gradually moves upward along the slot 603, thereby causing the moving frame 102 to move back, thus expanding the internal space of the fence assembly 1.
