Description

Technical Field

[0001] This utility model relates to the field of pig testing equipment, specifically a testing scale. Background Technology

[0002] During the breeding of pigs, it is necessary to measure data such as weight and back tags to assess their growth. During the measurement, staff drive the pigs into a feeding lane, where a measuring scale is placed. As the pigs walk along the lane, they are fed into the scale to restrain them, and various data are measured.

[0003] To better restrain pigs, measuring scales are typically narrow and long rectangular cages designed to fit the pigs' body shape. They have entrance and exit doors at the front and back, respectively. During measurement, the entrance door is opened and the exit door closed to allow the pig to enter the scale. After measurement, the exit door is opened to allow the pig to exit, then the exit door is closed and the entrance door opened again to allow the next pig to enter the scale for measurement. To facilitate herding pigs into the scale, the width of the scale is generally similar to the width of the herding aisle to prevent pigs from passing through the space between the scale and the side walls of the aisle. Figure 1 As shown. Due to the considerable length of the measuring scale, two operators are required to control the opening and closing of the entrance and exit gates during actual operation, which increases personnel costs. If the operator stands outside the pig-driving passage and moves back and forth between the entrance and exit gates to control their opening and closing, this method, while requiring only one operator, increases the workload and reduces efficiency.

Detailed Implementation

[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0037] Example

[0038] like Figure 2 As shown, this embodiment discloses a measuring scale, which includes a vehicle body 100 and an opening and closing mechanism 200. The left and right sides of the vehicle body 100 are side rails, the front and rear sides are an entrance door 120 and an exit door 110 respectively, and the bottom is a base plate. The two side rails, the entrance door 120, the exit door 110, and the base plate together form a frame structure with an opening at the top, as shown. Figure 2 As shown. Both the entrance door 120 and the exit door 110 can be opened and closed. Pigs can only enter the vehicle body 100 through the entrance door 120 and exit through the exit door 110. A weighing platform is installed on the bottom plate of the vehicle body 100, and a display screen connected to the weighing platform is installed on the side rail for displaying the weight. After the pigs enter the vehicle body 100, the weighing platform can weigh the pigs, and the measuring personnel can measure data such as the pig's back sling from above the vehicle body. The setting of the weighing platform and the display screen is existing technology, which is widely used in traditional pig weighing cage scales, and therefore will not be described in detail.

[0039] The opening and closing mechanism 200 is located on the vehicle body 100 near the entrance door 120 and is connected to the exit door 110. It is used to drive the exit door 110 to open or close. In use, only one measuring person needs to stand near the entrance door 120 to control the entrance door 120 and the exit door 110 at the same time. This solves the problem that traditional measuring scales require two measuring persons to control the entrance door 120 and the exit door 110 respectively, or that when one measuring person operates, the vehicle body 100 needs to run back and forth between the front and rear ends.

[0040] Specifically, such as Figure 3 , 4 As shown, the opening and closing mechanism 200 includes a swing assembly that can swing on the vehicle body 100 and a push rod 210 whose connecting end is connected to the swing assembly. The pushing end of the push rod 210 is connected to the exit door 110. The swing assembly can swing between the open position and the closed position. When the swing assembly swings from the closed position to the open position, it can push open the exit door 110 through the push rod 210. When the swing assembly swings from the open position to the closed position, it can pull the exit door 110 to close through the push rod 210.

[0041] The swing assembly includes a locking piece 250 and a swing arm 230. One end of the swing arm 230 is connected to the side rail of the vehicle body 100 via a swing arm pivot 220, and the other end is connected to the locking piece 250. Specifically, both ends of the swing arm 230 are provided with sleeves. One sleeve of the swing arm 230 is rotatably fitted onto the swing arm pivot 220, and the other sleeve is rotatably fitted onto the swing arm mounting shaft 280 provided on the locking piece 250, making both ends of the swing arm 230 movable. Therefore, the swing arm 230 can swing between the open and closed positions with the swing arm pivot 220 as the fulcrum. Figure 3 , 4 As shown. Similarly, the clip 250 is provided with a push rod shaft 260, and the connecting end of the push rod 210 is movably sleeved on the push rod shaft 260, as shown. Figure 4 As shown; an installation shaft is also provided on the exit door 110, and the pushing end of the push rod 210 is also movably sleeved on the installation shaft, as shown. Figure 2 As shown, both ends of the push rod 210 are movable, which can accommodate the push rod 210 to push back and forth.

[0042] When the swing arm 230 swings to the open or closed position, the locking piece 250 can be engaged with the vehicle body 100 to secure the swing arm 230. Specifically, as shown... Figure 4 As shown, the latch 250 is provided with a latch 270. When the swing arm 230 swings to the open or closed position, the latch 250 can be fastened to the side rail of the vehicle body 100 through the latch 270. Figure 3 As shown.

[0043] To facilitate the swinging assembly, a handle 240 is provided on the locking member 250. With this structure, when the exit door 110 needs to be opened, the operator lifts the handle 240 upwards, disengaging the locking member 250 from the side rail of the vehicle body 100. Then, the swing rod 230 is pushed towards the exit door 110, causing it to swing from the closed position to the open position. The locking member 250 engages with the side rail of the swing rod pivot 220 near the exit door 110. During this process, the push rod 210 is pushed towards the exit door 110, thus pushing the exit door 110 open forward. Figure 11 As shown. When it is necessary to close the exit door 110, lift the handle 240 again, and the latch 250 will disengage from the side rail of the vehicle body 100 again. Then, pull the swing arm 230 towards the entrance door 120, causing the swing arm 230 to swing from the open position to the closed position. The latch 250 will engage with the side rail of the swing arm pivot 220 near the entrance door 120. During this process, the push rod 210 is pulled towards the entrance door 120, thus the push rod 210 pulls the exit door 110 to close. Figure 2 As shown.

[0044] In addition, a latch assembly is provided on the vehicle body 100, and a latch assembly is provided on the entrance door 120. The latch assembly can be locked with the latch assembly to lock the entrance door 120.

[0045] like Figure 5 As shown, the latch assembly includes a sleeve 121 mounted on the entrance door 120 and a rod 400 with its lower end penetrating inside the sleeve 121. The rod 400 and the sleeve 121 are in clearance fit, allowing the rod 400 to move up and down along the sleeve 121. Additionally, a positioning piece 410 is provided on the rod 400. The diameter of the positioning piece 410 is larger than the inner diameter of the sleeve 121; therefore, the rod 400 will not fall downwards out of the sleeve 121 due to the obstruction of the positioning piece.

[0046] The locking assembly includes an upper fixing member 300 disposed on the upper part of the vehicle body 100. Specifically, the upper fixing member 300 can be disposed on the side rail of the vehicle body 100. Figure 6As shown, the upper fixing member 300 is provided with a blocking part 310 and an opening 320 for the insertion rod 400 to be inserted. That is, the upper fixing member 300 is V-shaped, and a blocking part 310 is provided on each of its two sides. The diameter of the positioning piece 410 is larger than the distance between the two blocking parts 310. Therefore, when the insertion rod 400 is inserted into the opening 320, the blocking part 310 can abut against the positioning piece 410 to limit the insertion rod 400 within the opening 320, so that the locking tongue assembly and the locking assembly are in a locked state. When closing the entrance door 120, the insertion rod 400 needs to be lifted upwards so that the positioning piece 410 is higher than the blocking part 310. Only then can the insertion rod 400 engage with the opening 320, allowing the entrance door 120 to close completely. After the insertion rod 400 is engaged with the opening 320, it is lowered. At this point, the positioning piece 410 abuts against the blocking part 310, and the locking tongue assembly and the latch assembly are locked, thus locking the exit door 120. Figure 7 As shown.

[0047] like Figure 8 As shown, the latch assembly also includes a lower fixing member 500 disposed at the lower part of the vehicle body 100. The lower fixing member 500 can be disposed at the lower part of the vehicle body 100, and the lower fixing member 500 is provided with an insertion hole 510. When the latch assembly and the latch assembly are in the locked state, the lower end of the insertion rod 400 is inserted into the insertion hole 510; that is, when the insertion rod 400 is engaged in the opening 320, the entrance door 120 is closed in place. When the insertion rod 400 is released, under the action of gravity, the lower end of the insertion rod 400 can be inserted into the insertion hole 510, thereby fixing the entrance door 120 at both the upper and lower ends.

[0048] As an alternative, such as Figure 8-10 As shown, a guide plate 520 is provided on the fixing member 500. The guide plate 520 is inclined. When the entrance door 120 is closed, the lower end of the insertion rod 400 contacts the guide plate 520. Since the guide plate 520 is inclined upward, as the entrance door 120 is further closed, the lower end of the push rod 400 slides along the guide plate 520 to the upper surface of the fixing member 500, and the insertion rod 400 is pushed up, so that the positioning piece 410 is higher than the blocking part 310, and the insertion rod 400 can be inserted into the opening 320. After the entrance door 120 is closed to the end, the lower end of the push rod 400 is aligned with the insertion hole 510, the push rod 400 loses support, and under the action of gravity, the push rod 400 falls, and the lower end of the push rod 400 is inserted into the insertion hole 510. The positioning piece 410 abuts against the blocking part 310, and the entrance door 120 is automatically locked. Figure 9 , 10 As shown. Therefore, in this embodiment, when in use, the measuring personnel only need to pull the entrance door 120 to close it, and the entrance door 120 will be automatically locked. During the closing process of the entrance door 120, it is not necessary for a person to manually lift the push rod 400 upward. Only when the entrance door 120 is opened is it necessary to manually lift the push rod 400 to unlock the entrance door 120, which makes the operation more convenient.

[0049] In specific configuration, a locking tongue assembly and a locking latch assembly can be installed on one or both sides of the vehicle body 100. Specifically, an upper fixing member 300 and a lower fixing member 500 can be installed on one side rail of the vehicle body 100. In this case, the upper fixing member 300 and the lower fixing member 500 can be installed on the side rail without the opening / closing mechanism 200. The sleeve 121 and the insert rod 400 are installed on the side of the entrance door 120 corresponding to the upper fixing member 300 and the lower fixing member 500. The other side of the entrance door 120 can be connected to the vehicle body 100 using a traditional rotatable connection method. Correspondingly, such as... Figure 2 As shown, upper fixing parts 300 and lower fixing parts 500 can be installed on both side rails of the vehicle body 100, while sleeves 121 and insert rods 400 are installed on both sides of the entrance door 120. This means that both sides of the vehicle body 100 are equipped with locking tongue assemblies and latch assemblies. In this case, the locking tongue assembly and latch assembly on one side can be set to a normally locked state, while the other side can be opened and closed normally. When both sides of the vehicle body 100 are equipped with locking tongue assemblies and latch assemblies, the entrance door 120 can be opened from either side as needed.

[0050] In addition, the vehicle body 100 is equipped with rollers 600 at the rear and handles 700 at the front, and foot supports 800 are provided around the bottom of the vehicle body 100. When normally placed, the vehicle body 100 is supported on the ground by the foot supports 800, at which time the rollers 600 are off the ground; when it is necessary to move the measuring scale, the operator holds the handles 700 and lifts the front of the vehicle body 100 so that the rollers 600 contact the ground, thus making it easy to drag the measuring scale.

[0051] In this embodiment, only one operator needs to stand near the entrance gate 120 to simultaneously control the opening and closing of the entrance gate and the exit gate. This solves the problem that when the traditional measuring scale is placed in the pig herding channel, two measuring operators are needed to control the entrance gate 120 and the exit gate 110 respectively, or when one measuring operator operates it, the vehicle body 100 needs to run back and forth between the front and rear ends.

[0052] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.

[0053] Furthermore, the specific embodiments described above are exemplary.
