Description
Technical Field
[0001] This utility model relates to the field of feeding monitoring technology, specifically a feeding amount monitoring device for livestock. Background Technology
[0002] With the intensive development of animal husbandry, precise breeding management has become a key factor in improving breeding efficiency, among which the refined control of the feeding process is particularly important. Existing livestock feeding monitoring devices include feed hoppers, feeding troughs, fences, and group gates. The group gates determine whether the target livestock needs feeding by recognizing ear tags. When the target livestock needs feeding, the group gates open automatically, allowing the target livestock to be placed in the fence. Then, the feed hoppers add feed to the feeding troughs inside the fence to feed the livestock. A weight sensor is installed under the feed hoppers, which combines the ear tag recognition data from the group gates with the weight data from the feed hoppers to accurately record the amount of feed given to each animal.
[0003] However, existing technologies have the following drawbacks:
[0004] (1) Since the weight sensor of the hopper can only analyze the amount of feed put out, it cannot analyze how much the livestock actually eats. When there is leftover feed in the feed trough, it will affect the accuracy of judging the amount of feed given to the livestock, and thus affect the accuracy of the breeding decision.
[0005] (2) Since livestock may produce pollutants such as saliva and hair during the feeding process, and the feeding bowl is exposed to the environment for a long time, it is also easy to get dusty. Over time, the feeding bowl will be continuously polluted, and the polluted feeding bowl will affect the quality of the feed, thus affecting the health of the livestock.
[0006] Therefore, it is necessary to design a feeding monitoring device that can record the amount of residual feed in the feeding bowl and automatically clean the feeding bowl. Utility Model Content
[0007] The purpose of this invention is to provide a feeding quantity monitoring device for livestock, so as to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, the present invention provides the following technical solution: a feeding monitoring device for livestock, comprising a feeding trough, wherein the feeding trough is set in front of the fence, the feeding trough includes a trough bottom and a shell, the shell is fixed to the fence, the trough bottom is set on a tray and can rise and fall with the tray, and a residual weight sensor is installed between the tray and the trough bottom.
[0009] The pallet is mounted on a parallelogram mechanism, which is mounted on a fence, and the pallet is oriented parallel to the ground.
[0010] A recycling bin is detachably fixed inside the fence in front of the tray;
[0011] A cleaning mechanism is installed in front of the fence. The cleaning mechanism includes a cleaning housing, which is fixed in front of the fence. A connecting rod is slidably installed inside the cleaning housing. A double-sloping spring pin is installed on the connecting rod. A conversion gear is rotatably installed behind the connecting rod. A cleaning scraper is fixed on the conversion gear.
[0012] Inside the cleaning housing, there is also a sliding conversion rack. One end of the conversion rack is engaged with a conversion gear, and the other end of the conversion rack is fixed with a slider that can contact a double-sloping spring pin.
[0013] The front end of the cleaning housing is equipped with a front spring pin, and the rear end is equipped with a rear spring pin. The slider can contact the front spring pin or the rear spring pin.
[0014] Preferably, the remaining weight sensor is electrically connected to the control module.
[0015] Preferably, the parallelogram mechanism is electrically connected to the control module. The parallelogram mechanism includes an active link, one end of which is rotatably mounted at point A at the bottom of the fence, and the other end of which is rotatably mounted at point B on the tray. One end of a driven link is rotatably mounted at point C on the tray, and the other end of which is rotatably mounted at point D at the bottom of the fence. Points A, B, C, and D form a parallelogram.
[0016] Preferably, the parallelogram mechanism also includes a lifting motor, which is fixed at the bottom of the fence, and the output shaft of the lifting motor is fixed at point A of the active connecting rod. The lifting motor is electrically connected to the control module.
[0017] Preferably, the cleaning mechanism is electrically connected to the control module. The cleaning mechanism also includes an active rack, which is fixed on a connecting rod. The active rack is meshed with an active gear, which is fixed on the output shaft of the cleaning motor. The cleaning motor is electrically connected to the control module.
[0018] Preferably, the cleaning motor is a right-angle motor, and the cleaning motor is fixed on the cleaning housing.
[0019] Preferably, the control module is installed on the fence, and the control module is a 32-bit microcontroller.
[0020] Preferably, a protective sleeve is fixed to the front of the connecting rod, and a conversion rack is slidably provided inside the protective sleeve.
[0021] Preferably, a camera is fixed to the top of the fence, and the camera is electrically connected to the control module.
[0022] Compared with the prior art, the beneficial effects of this utility model are: by placing the bottom of the basin on the tray and setting a residual weight sensor between the tray and the bottom of the basin, compared with the metering method of placing the weight sensor on the hopper, the actual feed intake of livestock is judged by the residual weight sensor, which improves the accuracy of judging the amount of feed for livestock and thus improves the accuracy of breeding decisions.
[0023] The basin bottom and tray are set on a parallelogram mechanism. The tray can remain parallel to the ground as it moves with the parallelogram mechanism. The movement of the tray separates the basin bottom from the shell. When the basin bottom descends to its limit position, the cleaning mechanism moves the cleaning scraper to the rear of the basin bottom while keeping the cleaning scraper away from the basin bottom. Then, while keeping the cleaning scraper pressed against the basin bottom, the cleaning mechanism moves the cleaning scraper to the front of the basin bottom, thereby scraping the feed residue and contaminants on the basin bottom into the recycling bin in front of the basin bottom. This reduces pollution, ensures the quality of newly added feed, and thus protects the health of livestock.
[0024] Because the recycling bin is located at the front of the bottom of the trough, the cleaning scraper removes feed residue and contaminants as it moves forward, preventing feed residue and contaminants from scattering everywhere. This reduces the space occupied behind the feeding trough, giving livestock that are feeding behind it more spacious room to move around. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] This utility model provides a technical solution: a livestock feed quantity monitoring device, such as... Figure 1 , 2 As shown, the device includes a feeding bowl, which is located in front of the fence 1. The feeding bowl includes a bowl bottom 3 and a shell 2. The shell 2 is fixed on the fence 1. The bowl bottom 3 is located on a tray 4 and can rise and fall with the tray 4. A residual weight sensor is installed between the tray 4 and the bowl bottom 3.
[0035] The basin bottom 3 is placed on the tray 4, and a residual weight sensor is set between the tray 4 and the basin bottom 3. Compared with the metering method of placing the weight sensor on the hopper, the actual feed intake of livestock is judged by the residual weight sensor, which improves the accuracy of judging the amount of feed to livestock and thus improves the accuracy of breeding decisions.
[0036] like Figure 1 , 2 As shown, the tray 4 is mounted on the parallelogram mechanism 20, which is mounted on the fence 1, and the tray 4 is oriented to be parallel to the ground.
[0037] like Figure 1 As shown, a recycling bin 5 is detachably fixed inside the fence 1 in front of the tray 4.
[0038] like Figure 1 , 3As shown in Figures 4 and 5, a cleaning mechanism 30 is provided in front of the fence 1. The cleaning mechanism 30 includes a cleaning housing 31, which is fixed in front of the fence 1. A connecting rod 32 is slidably arranged inside the cleaning housing 31. A double-sloping spring pin 33 is installed on the connecting rod 32. The double-sloping spring pin 33 is a type of existing spring pin, which includes a sleeve and a pin with double slopes. A spring is installed inside the sleeve. Under the action of the spring, the pin with double slopes can be kept in an extended state. In this embodiment, the double-sloping spring pin 33 is installed on the connecting rod 32 through the sleeve. A conversion gear 34 is rotatably arranged behind the connecting rod 32. A cleaning scraper 35 is fixed on the conversion gear 34.
[0039] like Figure 3 , 5 As shown, a conversion rack 36 is also slidably disposed inside the cleaning housing 31. One end of the conversion rack 36 is meshed with the conversion gear 34, and the other end of the conversion rack 36 is fixed with a slider 37, which can contact the double inclined spring pin 33.
[0040] like Figure 3 As shown, a front spring pin 38 is installed at the front end of the cleaning housing 31, and a rear spring pin 39 is installed at the rear end. The slider 37 can contact the front spring pin 38 or the rear spring pin 39. In this embodiment, the front spring pin 38 and the rear spring pin 39 are extended spring pins.
[0041] When the cleaning mechanism 30 is in its initial position, the double-sloping spring pin 33 prevents the slider 37 from moving forward relative to the connecting rod 32, and the cleaning scraper 35 is in a position away from the basin bottom 3. As the connecting rod 32 moves backward, it drives the conversion gear 34 to move backward, which in turn drives the cleaning scraper 35 to move backward. The backward movement of the connecting rod 32 can drive the double-sloping spring pin 33 to move backward, which in turn drives the slider 37 to move backward, which in turn drives the conversion rack 36 to move backward. During this process, the conversion rack 36 moves synchronously with the connecting rod 32, and the conversion gear 34 is relatively stationary relative to the conversion rack 36, and the conversion gear 34 does not rotate.
[0042] As the connecting rod 32 moves backward, the slider 37 first contacts the rear spring pin 39, and then squeezes the rear spring pin 39. When the rear spring pin 39 is compressed to its limit position, as the connecting rod 32 moves backward, the double-beveled spring pin 33 begins to shorten and gradually overlaps with the slider 37. When the double-beveled spring pin 33 and the slider 37 are completely overlapped, the double-beveled spring pin 33 no longer prevents the slider 37 from moving forward relative to the connecting rod 32. At this time, the slider 37 moves forward under the action of the rear spring pin 39. After the slider 37 moves forward, the double-beveled spring pin 33 pops out again. At this time, the double-beveled spring pin 33 prevents the slider 37 from moving backward relative to the connecting rod 32. After the slider 37 and the double-beveled spring pin 33 complete the above process, compared with before the above process, the slider 37 has moved forward relative to the connecting rod 32, which in turn causes the conversion rack 36 to move forward relative to the connecting rod 32, thereby driving the conversion gear 34 to rotate, which in turn drives the cleaning scraper 35 to press against the bottom of the basin 3.
[0043] After the cleaning scraper 35 presses against the basin bottom 3, the connecting rod 32 moves forward, which in turn drives the conversion gear 34 to move forward, thereby driving the cleaning scraper 35 to move forward. Figure 3 The image shows the state where the double-sloping spring pin 33 drives the slider 37 to move forward, thereby scraping off the feed residue and contaminants on the bottom of the basin 3, causing the food residue and contaminants to fall into the recycling cylinder 5. The forward movement of the connecting rod 32 can drive the double-sloping spring pin 33 to move forward, thereby driving the slider 37 to move forward, and then driving the conversion rack 36 to move forward. During this process, the conversion rack 36 moves synchronously with the connecting rod 32, and the conversion gear 34 is relatively stationary relative to the conversion rack 36, and the conversion gear 34 does not rotate.
[0044] As the connecting rod 32 moves forward, the slider 37 first contacts the front spring pin 38, then compresses it. Once the front spring pin 38 is compressed to its limit, as the connecting rod 32 continues to move forward, the double-sloping spring pin 33 begins to shorten and gradually overlaps with the slider 37. When the double-sloping spring pin 33 and the slider 37 are fully overlapped, the double-sloping spring pin 33 no longer prevents the slider 37 from moving backward relative to the connecting rod 32. At this point, the slider 37 moves backward under the action of the front spring pin 38. After the slider 37 moves backward, the double-sloping spring pin 33 pops out again, preventing the slider 37 from moving forward relative to the connecting rod 32. After the slider 37 and the double-sloping spring pin 33 complete the above process, compared with before the above process, the slider 37 moves backward relative to the connecting rod 32, which in turn causes the conversion rack 36 to move backward relative to the connecting rod 32, thereby driving the conversion gear 34 to rotate in the opposite direction, which in turn drives the cleaning scraper 35 away from the bottom of the basin 3, and the cleaning mechanism 30 returns to the initial position, waiting for the next cleaning work.
[0045] The basin bottom 3 and the tray 4 are set on the parallelogram mechanism 20. The tray 4 can remain parallel to the ground as the parallelogram mechanism 20 moves. The movement of the tray 4 separates the basin bottom 3 from the shell 2. When the basin bottom 3 descends to its limit position, the cleaning mechanism 30 moves the cleaning scraper 35 behind the basin bottom 3 while keeping the cleaning scraper 35 away from the basin bottom 3. Then, while keeping the cleaning scraper 35 pressed against the basin bottom 3, the cleaning mechanism 30 moves the cleaning scraper 35 in front of the basin bottom 3, thereby scraping the feed residue and contaminants on the basin bottom 3 into the recycling bin 5 in front of the basin bottom 3, reducing pollution, ensuring the quality of the feed added later, and thus ensuring the health of the livestock.
[0046] Since the recycling bin 5 is located in front of the bottom of the basin 3, the cleaning scraper 35 scrapes away feed residue and contaminants as it moves forward, avoiding the situation where feed residue and contaminants are scattered everywhere, reducing the space occupied behind the feeding basin, and giving the livestock that feed behind the feeding basin more spacious activity space.
[0047] To facilitate data analysis, the remaining weight sensor is electrically connected to the control module.
[0048] like Figure 2 , 6 As shown, the parallelogram mechanism 20 includes an active link 21. One end of the active link 21 is rotatably mounted at point A at the bottom of the fence 1, and the other end of the active link 21 is rotatably mounted at point B on the tray 4. One end of the driven link 22 is rotatably mounted at point C on the tray 4, and the other end of the driven link 22 is rotatably mounted at point D at the bottom of the fence 1. Points A, B, C, and D form a parallelogram.
[0049] like Figure 6 As shown, the parallelogram mechanism 20 also includes a lifting motor 23, which is fixed at the bottom of the fence 1. The output shaft of the lifting motor 23 is fixed at point A of the active connecting rod 21, and the lifting motor 23 is electrically connected to the control module.
[0050] Before cleaning the food bowl, the control module controls the lifting motor 23 to move. The lifting motor 23 drives the active connecting rod 21 to rotate forward, which in turn drives the driven connecting rod 22 to rotate forward, which in turn drives the tray 4 and the bowl bottom 3 fixed on the tray 4 to move downward and forward. After the bowl bottom 3 moves to the limit position, the cleaning work begins.
[0051] After cleaning is completed, the control module controls the lifting motor 23 to move. The lifting motor 23 drives the active connecting rod 21 to rotate backward, which in turn drives the driven connecting rod 22 to rotate backward, which in turn drives the tray 4 and the basin bottom 3 fixed on the tray 4 to move downward and forward, so that the basin bottom 3 returns to the bottom of the housing 2.
[0052] To facilitate driving the connecting rod 32, such as Figure 3, 7 As shown, the cleaning mechanism 30 is electrically connected to the control module. The cleaning mechanism 30 also includes a drive rack 40, which is fixed to the connecting rod 32. The drive rack 40 is meshed with a drive gear 41, which is fixed to the cleaning motor 42 (shown in...). Figure 7 On the output shaft of the (middle) motor, the cleaning motor 42 is electrically connected to the control module.
[0053] The cleaning motor 42 can drive the drive gear 41 to rotate, which in turn drives the drive rack 40 to move, which in turn drives the connecting rod 32 to move.
[0054] To facilitate fixing and cleaning the motor 42, such as Figure 7 As shown, the cleaning motor 42 is a right-angle motor, and the cleaning motor 42 is fixed on the cleaning housing 31.
[0055] For ease of control, the control module is installed on fence 1. The control module is a 32-bit microcontroller.
[0056] To improve the stability of the conversion rack 36 during movement, such as Figure 3 As shown, a protective sleeve 43 is fixed to the front of the connecting rod 32, and a conversion rack 36 is slidably arranged inside the protective sleeve 43.
[0057] To facilitate monitoring of livestock feeding, such as Figure 1 As shown, a camera 6 is fixed to the top of the fence 1, and the camera 6 is electrically connected to the control module.
[0058] Working process: Before cleaning the food basin, the control module controls the lifting motor 23 to move. The lifting motor 23 drives the active connecting rod 21 to rotate forward, which in turn drives the driven connecting rod 22 to rotate forward, which in turn drives the tray 4 and the basin bottom 3 fixed on the tray 4 to move downward and forward.
[0059] After the basin bottom 3 moves to its limit position, when the cleaning mechanism 30 is in its initial position, the double inclined spring pin 33 prevents the slider 37 from moving forward relative to the connecting rod 32, and the cleaning scraper 35 is in a position away from the basin bottom 3. The control module controls the cleaning motor 42 to move, the cleaning motor 42 drives the drive gear 41 to rotate, which in turn drives the drive rack 40 to move backward, which in turn drives the connecting rod 32 to move backward, which in turn drives the conversion gear 34 to move backward, which in turn drives the cleaning scraper 35 to move backward.
[0060] The backward movement of the connecting rod 32 can drive the double inclined spring pin 33 to move backward, which in turn drives the slider 37 to move backward, which in turn drives the conversion rack 36 to move backward. During this process, the conversion rack 36 moves synchronously with the connecting rod 32, and the conversion gear 34 is relatively stationary relative to the conversion rack 36, and the conversion gear 34 does not rotate.
[0061] As the connecting rod 32 moves backward, the slider 37 first contacts the rear spring pin 39, then compresses the rear spring pin 39. When the rear spring pin 39 is compressed to its limit position, as the connecting rod 32 moves backward, the double-beveled spring pin 33 begins to shorten and gradually overlaps with the slider 37. When the double-beveled spring pin 33 and the slider 37 are completely overlapped, the double-beveled spring pin 33 no longer prevents the slider 37 from moving forward relative to the connecting rod 32. At this time, the slider 37 moves forward under the action of the rear spring pin 39. After the slider 37 moves forward, the double-beveled spring pin 33 pops out again, and at this time, the double-beveled spring pin 33 prevents the slider 37 from moving backward relative to the connecting rod 32. After the slider 37 and the double-beveled spring pin 33 complete the above process, compared with before the above process, the slider 37 has moved forward relative to the connecting rod 32, which in turn causes the conversion rack 36 to move forward relative to the connecting rod 32, thereby driving the conversion gear 34 to rotate, which in turn causes the cleaning scraper 35 to press against the bottom of the basin 3.
[0062] After the cleaning scraper 35 presses against the bottom of the basin 3, the double-sloping spring pin 33 prevents the slider 37 from moving backward relative to the connecting rod 32. The cleaning scraper 35 is in the position of pressing against the bottom of the basin 3. The control module controls the cleaning motor 42 to move again. The cleaning motor 42 drives the drive gear 41 to rotate in the opposite direction, which in turn drives the drive rack 40 to move forward, which in turn drives the connecting rod 32 to move forward, which in turn drives the conversion gear 34 to move forward, which in turn drives the cleaning scraper 35 to move forward, thereby scraping off the feed residue and contaminants on the bottom of the basin 3, so that the food residue and contaminants fall into the recycling cylinder 5.
[0063] The forward movement of the connecting rod 32 can drive the double inclined spring pin 33 to move forward, which in turn drives the slider 37 to move forward, which in turn drives the conversion rack 36 to move forward. During this process, the conversion rack 36 moves synchronously with the connecting rod 32, and the conversion gear 34 is relatively stationary relative to the conversion rack 36, and the conversion gear 34 does not rotate.
[0064] As the connecting rod 32 moves forward, the slider 37 first contacts the front spring pin 38, then compresses it. Once the front spring pin 38 is compressed to its limit, as the connecting rod 32 continues to move forward, the double-sloping spring pin 33 begins to shorten and gradually overlaps with the slider 37. When the double-sloping spring pin 33 and the slider 37 are fully overlapped, the double-sloping spring pin 33 no longer prevents the slider 37 from moving backward relative to the connecting rod 32. At this point, the slider 37 moves backward under the action of the front spring pin 38. After the slider 37 moves backward, the double-sloping spring pin 33 pops out again, preventing the slider 37 from moving forward relative to the connecting rod 32. After the slider 37 and the double-sloping spring pin 33 complete the above process, compared with before the above process, the slider 37 moves backward relative to the connecting rod 32, which in turn causes the conversion rack 36 to move backward relative to the connecting rod 32, thereby driving the conversion gear 34 to rotate in the opposite direction, which in turn drives the cleaning scraper 35 away from the bottom of the basin 3, and the cleaning mechanism 30 returns to the initial position, waiting for the next cleaning work.
[0065] After the cleaning mechanism 30 returns to its initial position, the control module controls the lifting motor 23 to operate. The lifting motor 23 drives the active connecting rod 21 to rotate backward, which in turn drives the driven connecting rod 22 to rotate backward. This, in turn, causes the tray 4 and the basin bottom 3 fixed on the tray 4 to move upward and backward, so that the basin bottom 3 returns to the bottom of the housing 2.
[0066] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
