Detailed Implementation

[0026] 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.

[0027] The purpose of this invention is to provide a feeding device suitable for primates, in order to solve the problems existing in the prior art, and to facilitate researchers in monitoring and analyzing the exploratory activities and food cravings of primates.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This invention provides a feeding device suitable for primates, such as... Figures 1 to 6 As shown, it includes a housing 1, a food storage tank 2, a turntable 3, a first rotating shaft 4, and an operating device 5; wherein, the turntable 3 is disposed inside the housing 1, and the first rotating shaft 4 is axially disposed in the middle of the turntable 3. The two ends of the first rotating shaft 4 are rotatably connected to the side wall of the housing 1 through bearings, and a groove 31 is formed inwardly on the outer peripheral side wall of the turntable 3; the food storage tank 2 has a food outlet, the turntable 3 is located below the food outlet of the food storage tank 2, and the turntable 3 can prevent the food in the food storage tank 2 from falling from the food outlet.

[0030] The first end of the first rotating shaft 4 passes through the side wall of the housing 1 and extends outward. The first end of the first rotating shaft 4 is connected and fixed to the operating device 5. That is, the operating device 5 can drive the first rotating shaft 4 and the turntable 3 to rotate synchronously around the same axis. Furthermore, the rotating device 5 can drive the turntable 3 to rotate so that the groove 31 rotates to a position corresponding to and connected with the food storage tank 2. At this time, the food in the food storage tank 2 can fall into the groove 31 from the food outlet.

[0031] The operating device 5 continues to drive the turntable 3 to rotate, which allows the food in the groove 31 to fall to the inner bottom of the shell 1; a feeding port is provided on the lower part of the side wall of the shell 1, which is connected to the inner bottom of the shell 1, so that the food falling to the inner bottom of the shell 1 can roll along the inner bottom of the shell 1 to the feeding port for primates to eat.

[0032] When primates rotate the control device 5, they can obtain food rewards on their own. This not only improves their flexibility and coordination but also increases their enthusiasm and variety in foraging. Furthermore, the fact that food can only be obtained by rotating the control device makes it easier for researchers to monitor and analyze the primates' exploration activities and food intake in real time.

[0033] In some implementations, such as Figure 5 As shown, it also includes a ratchet 6, a second rotating shaft 7, a first connecting plate 8, an elastic element 9, and a lever 10; wherein, the other end of the first rotating shaft 4 passes through the side wall of the housing 1 and is connected and fixed to the middle of the ratchet 6, the first rotating shaft 4 and the ratchet 6 can rotate synchronously, one end of the second rotating shaft 7 is connected and fixed to the side wall of the housing 1, and the other end of the second rotating shaft 7 is rotatably connected to the lever 10, that is, the lever 10 can rotate around the second rotating shaft 7; one side of the first connecting plate 8 is connected and fixed to the side wall of the housing 1.

[0034] The lever 10 of this utility model is generally L-shaped. An elastic element 9 is provided between one end of the lever 10 and the first connecting plate 8. The two ends of the elastic element 9 are respectively connected to the lever 10 and the first connecting plate 8. Under the elastic force of the elastic element 9, the other end of the lever 10 can always abut against the outer wall of the ratchet 6. The outer wall of the ratchet 6 is provided with multiple ratchet teeth along the circumference. The other end of the lever 10 can engage with the ratchet teeth of the ratchet 6 to limit the rotation direction of the ratchet 6. That is, the lever 10 can limit the ratchet 6 to rotate in the same direction and prevent it from reversing.

[0035] For example, when ratchet 6 rotates clockwise, lever 10 does not engage with the ratchet teeth, but when ratchet 6 tends to rotate counterclockwise, lever 10 engages with the ratchet teeth, so that lever 10 can limit ratchet 6 to rotate only in the clockwise direction; understandably, lever 10 can also limit ratchet 6 to rotate only in the counterclockwise direction.

[0036] This invention limits the rotation direction of the ratchet 6. Since the control device 5 and the turntable 3 rotate synchronously with the ratchet 6, the control device 5 and the turntable 3 are limited to rotate in the same direction, preventing reverse rotation. By adopting the design to prevent reverse rotation, it is ensured that the animal must rotate a full circle in the same direction to obtain food, thus ensuring that the amount of activity and the amount of food obtained are proportional.

[0037] It should be noted that the elastic element 9 is a spring or other elastic element, and this utility model does not make a specific limitation; and those skilled in the art can also set a configuration block on the turntable 3, which can make the groove 31 on the turntable 3 located at the bottom end in the initial state; when the animal just starts to rotate the control device 5 to get the food, it needs to rotate one full circle to get the food.

[0038] In some implementations, such as Figure 4 As shown, the control device 5 of this invention is a steering wheel structure, with the center of the steering wheel sleeved on one end of the first rotating shaft 4 and connected and fixed to the first rotating shaft 4. The steering wheel design of this invention increases the novelty and interest of the animal husbandry environment.

[0039] In some implementations, see further reference. Figure 5 and Figure 6 As shown, it also includes a brake disc 11, a brake band 12, a tension adjustment assembly 13, and a second connecting plate 14; wherein, the middle part of the brake disc 11 is sleeved on the first rotating shaft 4 and rotates synchronously with the first rotating shaft 4, and one side of the second connecting plate 14 is connected and fixed to the side wall of the housing 1; the brake band 12 is sleeved on the outer peripheral wall of the brake disc 11, and both ends of the brake band 12 in the length direction are connected to the second connecting plate 14; for example, both ends of the brake band 12 in the length direction pass through the second connecting plate 14 and are connected to fasteners.

[0040] Furthermore, at least one end of the brake band 12 along its length is connected to a tension adjustment assembly 13, which is used to adjust the tension of the brake band 12.

[0041] like Figure 6 As shown, the tension adjustment assembly 13 includes a dial 131 and an adjusting nut 132; a first wedge block 18 and a second wedge block 19 are provided on one side of the second connecting plate 14; one end of the brake band 12 passes through the second connecting plate 14 and the first wedge block 18 and is threadedly connected to the fastening nut 20, one side of which is in contact with the inclined surface of the first wedge block 18; the other end of the brake band 12 passes through the second connecting plate 14 and the second wedge block 19 and is threadedly connected to the adjusting nut 132, and a dial 131 is provided between the adjusting nut 132 and the second wedge block 19, on which multiple scale lines for indicating the tension of the brake band 12 are provided circumferentially.

[0042] It should be noted that one side of the dial 131 of this utility model is in contact with the inclined surface of the second wedge block 19. Those skilled in the art can lock the dial 131 and the second wedge block 19 circumferentially, so that when the tightness of the brake band 12 is adjusted by turning the adjusting nut 132, the dial 131 does not rotate with the adjusting nut 132. Furthermore, an indicator arrow is provided on the adjusting nut 132. When the adjusting nut 132 is rotated to correspond to different scale lines on the dial 131, the tightness of the contact between the brake band 12 and the brake disc 11 is different.

[0043] This invention can adjust the force required to rotate the control device 5 by controlling the tightness of the brake band 12. The force required to rotate the steering wheel is continuously adjustable and the force level can be precisely controlled.

[0044] like Figure 5 As shown, in another embodiment, the tension adjustment component 13 of this utility model can also be configured to include a spring and an adjusting nut 132. Both ends of the brake band 12 pass through the second connecting plate and the corresponding wedge block and are threadedly connected to the adjusting nut 132. A spring is provided between the adjusting nut 132 and the wedge block. When the adjusting nut 132 is turned, the deformation and elasticity of the spring are changed, thereby adjusting the tension of the brake band 12.

[0045] In some implementations, such as Figure 1 As shown, it also includes a sensor assembly 15, which includes a receiving tube and a transmitting tube. The receiving tube and the transmitting tube are respectively disposed on both sides of the ratchet 6, and the transmitting tube emits towards the receiving tube.

[0046] The ratchet 6 has detection holes 61 extending through both sides. These detection holes 61 can rotate around the axis of the first rotating shaft 4 and pass between the transmitting tube and the receiving tube. When the detection hole 61 rotates one revolution around the axis, and it reaches the position between the transmitting tube and the receiving tube, the light emitted by the transmitting tube can be received by the receiving tube. At this time, the count of the number of revolutions of the ratchet 6 is incremented by 1. The number of revolutions of the ratchet 6 can be detected by the sensor assembly 15, which in turn can detect the number of revolutions of the turntable 3.

[0047] It should be noted that the sensor component 15 of this utility model can be a light sensor or other types of sensors, as long as it can achieve the effect of detecting the number of rotations of the ratchet 6. This utility model does not make a specific limitation in this regard. Furthermore, the detection hole 61 of this utility model can be set as an arc-shaped hole, with the center of the circle containing the arc-shaped hole located on the axis of the first rotating shaft 4. Obviously, those skilled in the art can also set the detection hole 61 to other shapes. This utility model does not make a specific limitation in this regard.

[0048] In some implementations, such as Figure 2As shown, the food storage trough 2 of this utility model has a funnel-shaped structure and is located inside the shell 1. The upper end of the food storage trough 2 is the food inlet and the lower end is the food outlet. The food outlet has an arc-shaped structure that is adapted to the outer periphery of the turntable 3. There is a certain gap between the outer periphery of the turntable 3 and the food outlet of the food storage trough 2. The gap is designed to prevent the food storage trough 2 from affecting the rotation of the turntable 3. The gap should not be too large to prevent the food in the food storage trough 2 from falling out of the gap.

[0049] In some embodiments, at least one side panel of the housing 1 is made of a transparent material to allow food to fall through; in a specific embodiment, the front and rear side panels of the housing 1 are... Figure 1 The first side plate 21 and the second side plate 22 are both made of transparent acrylic sheets. The two ends of the first rotating shaft 4 are rotatably connected to the first side plate 21 and the second side plate 22 respectively through bearings.

[0050] The rest of the housing 1 is made of stainless steel to form an integral stainless steel frame, in order to prevent the device from being damaged by animals during the experiment.

[0051] The top of the shell 1 is provided with an openable cover 16. After opening the cover 16, food can be placed into the food storage tank 2.

[0052] In some implementations, such as Figure 3 As shown, it also includes a feeding box 17, which is connected to the position on the shell 1 where the feeding opening 23 is provided; the inner bottom of the shell 1 is inclined, that is, the shell 1 is inclined downward from the end away from the feeding opening 23 to the end closer to the feeding opening 23. During the rotation of the groove 31, the food in the groove 31 falls to the inner bottom of the shell 1. Due to the inclined inner bottom of the shell 1, the food can roll down the inner bottom of the shell 1 to the feeding opening 23 and finally roll into the feeding box 17 for the animal to take.

[0053] In some embodiments, a control device is also included, with the sensor assembly 15 electrically connected to the control device. The sensor assembly 15 is used to detect the number of rotations of the ratchet 6 and feed the detection result back to the control device. The control device of this invention can be a computer, etc.

[0054] When using the feeding device of this utility model applicable to primates:

[0055] Food is placed in the food storage trough 2. By turning the steering wheel, the animal can rotate the turntable 3, causing the groove 31 to rotate to the lower position of the food storage trough 2. At this time, the food in the food storage trough 2 can fall into the groove 31. As the turntable 3 continues to rotate, because the groove 31 is misaligned with the food storage trough 2, the turntable 3 can prevent the food from falling. During the rotation of the groove 31, the food in the groove 31 can fall to the inner bottom of the shell 1. Because the inner bottom of the shell 1 is inclined, the food can roll down along the inner bottom of the shell 1 into the feeding box 17.

[0056] When the animal turns the steering wheel, the ratchet 6 rotates synchronously with the steering wheel. The detection hole 61 on the ratchet 6 counts each time it rotates past the sensor assembly 15, and the sensor assembly 15 feeds back the counting result to the control device. Furthermore, one end of the lever 10 always abuts against the outer wall of the ratchet 6, and the lever 10 can engage with the ratchet teeth on the ratchet 6 to limit the ratchet 6 to rotating only in one direction and not in the opposite direction.

[0057] This invention enables the steering wheel to be turned by the cooperation of the brake band 12 and the brake disc 11, requiring a certain amount of force; and the tightness of the brake band can be adjusted by turning the adjusting nut 132. When the adjusting nut 132 corresponds to different scale lines on the corresponding scale 131, the tightness of the corresponding brake band 12 is different.

[0058] This utility model adopts a steering wheel-based food-taking design, and the force required to turn the steering wheel is continuously adjustable, allowing for precise control of the force level.

[0059] This invention also incorporates a design to prevent the steering wheel from reversing, ensuring that the animal must turn a full circle in the same direction to obtain food, thus ensuring that the amount of activity and the amount of food obtained are proportional.

[0060] The device of this invention adopts an integral stainless steel design, which ensures that the device will not be damaged by animals during the experiment.

[0061] The device of this invention includes a rotation feedback system, which can be connected to a computer to automatically obtain the time point and number of rotations for each rotation. Combined with parameters such as force and food quantity, the experimenter can quantitatively analyze the animal's exploratory behavior and food craving.

[0062] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
