Detailed Implementation

[0035] 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.

[0036] The purpose of this invention is to provide a feeding device to solve the problems existing in the prior art, and to a certain extent avoid the situation where fruit is squeezed and deformed or crushed during the feeding of fruit-type foods.

[0037] 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.

[0038] Example 1

[0039] This embodiment provides a feeding device, such as Figures 1 to 4 As shown, it includes a first channel 1, a second channel 2, and a pushing component 3. The first channel 1 is arranged vertically and stores fruit pieces to be placed inside. The top of the first channel 1 is an inlet 12, and the bottom is an opening 11. The second channel 2 is located below the first channel 1 and communicates with the bottom opening 11 of the first channel 1. The fruit pieces to be placed in the first channel 1 can fall into the second channel 2 from the bottom opening 11 under their own gravity. The second channel 2 is arranged horizontally, and one end of the second channel 2 is an outlet 21, which corresponds to the position of the feeding device 8.

[0040] It should be noted that this embodiment is illustrated using the example of the first channel 1 being arranged vertically. Those skilled in the art can also configure the first channel 1 at a small angle to the vertical direction. Furthermore, this embodiment is illustrated using the example of the second channel 2 being arranged horizontally. Those skilled in the art can also configure the second channel 2 at a small angle to the horizontal direction. This embodiment is illustrated using the example of an entrance 12 being located at the top of the first channel 1. Those skilled in the art can also configure the entrance 12 at other locations above the first channel 1. This utility model is not specifically limited in any way.

[0041] The pushing component 3 includes a pushing platform 32, which is located at one end of the second channel 2 away from the outlet 21. The pushing platform 32 can slide along the second channel 2, and its sliding path passes through a first position away from the outlet 21 and a second position close to the outlet 21. During the process of sliding from the first position to the second position, the pushing platform 32 passes through the position in the second channel 2 corresponding to the opening 11, thereby pushing the fruit pieces falling from the opening 11 to the outlet 21, so that the fruit pieces fall into the feeding device 8 for the animals to pick up. Figure 2 The push platform 32 is in the first position, at which time the fruit pieces in the first channel 1 can fall from the bottom opening 11 into the second channel 2. Figure 3 When the push platform 32 is in the second position, it can block the opening 11, preventing the fruit pieces in the first channel 1 from falling. That is, the push platform 32 can gradually block the opening 11 as it slides from the first position to the second position. The push platform 32 can also return from the second position to the initial first position for the next pushing operation.

[0042] In this embodiment, the pushing component 3 further includes a driving device 31, which is connected to the thrust table 32 for driving the thrust table 32 to reciprocate along the second channel 2. The thrust table 32 includes a pushing part 321 and a limiting part 322. The limiting part 322 is disposed at the end of the top end face of the pushing part 321 away from the outlet 21. Along the pushing direction, the size of the limiting part 322 is smaller than the size of the pushing part 321. The pushing part 321 can slide along the second channel 2 from a first position to a second position, such as... Figure 2 As shown, when the pushing part 321 is in the first position, the opening 11 is connected to the second channel 2; the height dimension of the pushing part 321 along the vertical sliding direction is adapted to the height dimension of the opening 11 from the bottom end of the second channel 2. As the pushing part 321 slides towards the second position, the top of the pushing part 321 can gradually block the opening 11. This blocking should be understood as the top of the pushing part 321 preventing other fruit pieces in the first channel 1 from continuing to fall from the opening 11. The top of the pushing part 321 can abut against or be slightly lower than the opening 11, as long as it ensures that the apple pieces no longer fall; and as... Figure 3 As shown, when the pushing part 321 is in the second position, the limiting part 322 abuts against the side wall of the first channel 1, that is, the limiting part 322 abuts against the side of the first vertical plate 13 away from the outlet 21.

[0043] It should be noted that the height of the pushing part 321 in this embodiment is adapted to the height of the opening 11 from the bottom of the second channel 2. It should be understood that the height of the pushing part 321 can be equal to or slightly less than the height of the opening 11 from the bottom of the second channel 2, so that the pushing part 321 can slide along the second channel 2 and the top of the pushing part 321 can also block the opening 11.

[0044] In this embodiment, the feeding device further includes a housing 4, which includes a first side plate 41, a second side plate 42, a third side plate 43, a bottom plate 44, and a cover plate 45; wherein, in Figure 2 , Figure 3 and Figure 4 To make it easier to show the internal structure, the first side plate 41 was removed.

[0045] The inner bottom of the outer casing 4 is provided with a second channel 2 arranged horizontally, and one end of the bottom of the outer casing 4 forms an outlet 21 connecting the second channel 2 and the outside. Inside the outer casing 4, along the sliding direction of the push platform 32, a vertical and parallel first vertical plate 13 and a second vertical plate 14 are arranged sequentially, that is, the opposite sides of the first vertical plate 13 and the second vertical plate 14 are perpendicular to the sliding direction of the push platform 32; there is a gap between the bottom end of the first vertical plate 13 and the inner bottom end of the outer casing 4, and there is a gap between the bottom end of the second vertical plate 14 and the inner bottom end of the outer casing 4. The positions of the bottom ends of the first vertical plate 13 and the second vertical plate 14 are the positions of the opening 11; and the distance between the bottom end of the first vertical plate 13 and the inner bottom end of the outer casing 4 is equal to the distance between the second vertical plate 14 and the inner bottom end of the outer casing 4. The second vertical plate 13 and the second vertical plate 14 are both fixedly connected to the first side plate 41 and the second side plate 42, and together they form the first channel 1.

[0046] It should be noted that in this embodiment, the second vertical plate 14 is closer to the outlet 21 than the second vertical plate 13; those skilled in the art can also set it so that the first vertical plate 13 is closer to the outlet 21 than the second vertical plate 14, that is, the positions of the first vertical plate 13 and the second vertical plate 14 can be interchanged, and correspondingly, the limiting plate 322 of the thrust table 32 can abut and limit the second vertical plate 14.

[0047] In this embodiment, the height of the side of the pushing part 321 perpendicular to the sliding direction and close to the outlet 21 is adapted to the maximum size of the fruit block along the sliding direction. This adaptation should be understood as the height of the side of the pushing part 321 perpendicular to the sliding direction being equal to or slightly less than the maximum size of the fruit block along the sliding direction, so as to ensure that the pushing part 321 can push the first fruit block that has completely fallen into the second channel 2 without squeezing the second fruit block above the first fruit block.

[0048] Furthermore, the distance between the bottom end of the first vertical plate 13 or the bottom end of the second vertical plate 14 and the bottom end of the outer shell 4 is matched with the maximum size of the fruit block along the sliding direction. This matching should be understood as the distance between the bottom end of the first vertical plate 13 or the bottom end of the second vertical plate 14 and the bottom end of the outer shell 4 being equal to or slightly greater than the maximum size of the fruit block along the sliding direction. This ensures that the first fruit block at the bottom can fall completely into the second channel 2 and that the second fruit block is entirely or mostly located in the first channel 1, so that the pushing part 321 only pushes the first fruit block without squeezing the second fruit block.

[0049] Therefore, this invention can ensure that the pushing part 321 pushes exactly one piece of fruit to the outlet 21 each time, avoiding the situation where the fruit is squeezed and deformed or jammed and crushed during the pushing process.

[0050] In this embodiment, a horizontally arranged partition 5 is installed in the cavity above the pushing component 3. The partition 5 has a first cavity above it and a second cavity below it. The pushing component 3 is disposed in the second cavity. The first cavity is used to store the fruit to be fed. The top of the first cavity is provided with an openable and closable cover 45. Specifically, one end of the cover 45 is hinged to the third side plate 43, and the other end is an opening and closing end. The opening and closing end can be locked or opened with the top of the first vertical plate 13.

[0051] In this embodiment, as Figure 2 As shown, multiple protruding structures 7 are arranged on the opposite end faces of the first vertical plate 13 and the second vertical plate 14. These protruding structures 7 increase the contact friction between the fruit pieces stored in the first channel 1 and the side wall of the first channel 1, thereby reducing the squeezing force between the stacked fruit pieces in the first channel 1, but do not restrict the fruit pieces from falling under the action of gravity. It should be noted that those skilled in the art can specifically set the size, shape and arrangement of the protruding structures 7, and this utility model does not make specific limitations.

[0052] In this embodiment, hooks 46 are respectively provided on both sides of the opening 21 at the bottom of the outer shell 4. A retaining plate 47 connected to the bottom plate 44 is provided below the hooks 46. The hooks 46 are used to engage with the side wall of the feeding device 8. In this embodiment, the feeding device 8 is a feeding box. (See attached image.) Figure 1 The diagram shows the installation of the feeding device and the rearing cage 9 of this utility model. During installation, the feeding box is located inside the rearing cage 9, and the outer shell 4 is located outside the rearing cage 9. The hook 46 on the outer shell 4 extends into the rearing cage 9 and engages with the side wall of the feeding box. A locking plate 47 is spaced from the side wall of the feeding box and is secured to the crossbeam of the rearing cage 9. The feeding box and the locking plate 47 are also connected and fixed by fasteners. A connecting plate 48 is provided on the top of the outer shell 4. This connecting plate 48 is located inside the rearing cage 9 and is connected to the side wall of the outer shell 4 by fasteners, thereby achieving a connection and fixation with the rearing cage 9. The fasteners mentioned in this embodiment can be bolts, screws, or other components capable of achieving a fastening connection.

[0053] In this embodiment, a control system is also included. The control system includes a timing module, an I / O module, and a relay. The timing module controls the output of a level signal to the relay after a set time is reached during daily feeding, i.e., the timing module can control the on / off state of the relay. In experimental scenarios, after a trained animal completes a certain behavior, the behavior triggers a level signal, which is collected by the I / O module of the control system. The I / O module controls the output of the level signal to the relay, i.e., the I / O module can control the on / off state of the relay. Alternatively, in experimental scenarios, animal behavior is monitored by real-time video recording, and it is determined whether to feed the animal as a reward. When feeding is required, a level signal is also output to the relay. The driving device 31 in this embodiment is an electric push rod. The relay is connected to the power supply of the electric push rod to control the on / off state of the power supply. When the relay receives the level signal, it becomes conductive, thereby turning on the power to the electric push rod, causing the electric push rod to extend and retract, and driving the push platform 32 to push to achieve automatic feeding. During feeding, the number of times the electric push rod extends and retracts can be controlled by controlling the number of output level signals, so as to achieve timed and quantitative feeding, saving manpower and avoiding waste caused by overfeeding at one time.

[0054] In this embodiment, the first side plate 41 and the second side plate 42 of the outer casing 4 are made of transparent material so as to observe the operation inside the device. For example, transparent PC board, acrylic board or other transparent material can be used.

[0055] The third side plate 43, bottom plate 44, cover plate 45, first vertical plate 13, and second vertical plate 14 are all made of metal, such as stainless steel. The overall frame structure is sturdy and not easily shaken. It should be noted that those skilled in the art can choose the specific materials of the third side plate 43, bottom plate 44, cover plate 45, first vertical plate 13, and second vertical plate 14 according to the actual situation. This utility model does not make specific limitations.

[0056] Furthermore, the push platform 32 in this embodiment is made of plastic, which ensures that the fruit pieces are evenly stressed during the pushing process, preventing them from being squeezed and deformed. It is understood that the push platform 32 can also be made of other materials, and this invention does not impose specific limitations on it.

[0057] In use, for example, when feeding an animal fruit such as an apple, the feeding device of this embodiment cuts the apple into pieces using an apple slicer and places the pieces into the first channel 1. At this time, the push platform 32 is in the first position, and the apple pieces fall from the opening 11 at the bottom of the first channel 1 into the second channel 2. The drive device 31 is controlled to move at regular intervals or according to the animal's behavior. The drive device 31 drives the push platform 32 to slide from the first position along the second channel 2 to the second position, pushing the apple pieces that have fallen into the second channel 2 to the outlet 21 and dropping them into the feeding device 8 for the animal to pick up. At this time, the push platform 32 can also block the opening 11. Then the drive device 31 can drive the push platform 32 back from the second position to the first position. At this time, the apple pieces in the first channel 1 can fall again from the opening 11 into the second channel 2 for the next feeding. The cross-sectional dimensions of the first channel 1 are adapted to the size of the apple block. The height of the opening 11 from the bottom of the second channel 2, i.e., the height of the bottom of the first vertical plate 13 or the second vertical plate 14 from the bottom of the outer shell 4, is adapted to the size of the apple block. The height of the pushing part 321 is adapted to the size of the apple block, which allows the apple block to fall smoothly into the second channel 2 under the action of gravity and avoids jamming. The pushing platform 32 can push one apple block at a time.

[0058] It should be noted that this embodiment is illustrated by taking the pusher 32 pushing one piece of fruit at a time as an example. Those skilled in the art can specifically adjust the height of the opening 11 from the inner bottom of the second channel 2 and the height of the pusher 321 to push two or more pieces of apple at a time; this utility model is not specifically limited.

[0059] This invention enables the timed and quantitative feeding of primate laboratory animals, effectively saving manpower and time. It has a wide range of applications and can be used in daily feeding scenarios as well as in experimental testing. As a reward device, it can be used to reward primate laboratory animals with fruit pieces before and after experiments.

One end of the second slider 62 extends into the assembly groove 65 and connects with the elastic element 64, while the other end extends out of the assembly groove 65.

[0064] When the slider assembly engages with the slide groove 15, the side of the first slider 61 closest to the adjusting plate 63 and the side of the second slider 62 furthest from the adjusting plate 63 respectively abut against the two opposite sides of the inner wall of the slide groove 15. At this time, the elastic element 64 between the first slider 61 and the second slider 62 is in a compressed state, and the elastic force of the elastic element 64 makes the first slider 61 and the second slider 62 press tightly against the inner wall of the slide groove 15.

[0065] When the slider assembly slides along the slide groove 15, pressing the adjustment plate 63 causes the second slider 62 to move into the assembly groove 65 of the first slider 61 and compress the elastic element 64, thereby reducing the overall thickness of the first slider 61 and the second slider 62. At this time, the first slider 61 and the second slider 62 are no longer pressed against the inner wall of the slide groove 15, and the adjustment assembly 6 can slide along the slide groove 15 as a whole.

[0066] like Figure 6As shown, when the adjusting component 6 slides vertically downwards a certain distance, the bottom of the adjusting plate 63 of the adjusting component 6 is lower than the bottom of the first vertical plate 13 and the second vertical plate 14. The position of the bottom of the two adjusting plates 63 is the position of the opening 11 of the first channel 1. That is, the position of the opening 11 changes with the sliding of the adjusting component 6, thereby adjusting the distance between the opening 11 and the inner bottom of the outer shell 4. When feeding fruit pieces of different sizes, the adjusting component 6 is slid to make the distance between the opening 11 and the inner bottom of the outer shell 4 match the size of the fruit pieces, preventing the fruit pieces from not falling completely into the second channel during the pushing process and thus squeezing them. For example, when feeding apple pieces, the position of the adjusting component 6 is adjusted according to the size of the apple pieces so that the distance between the opening 11 and the inner bottom of the outer shell 4 ensures that one or more apple pieces fall into the second channel 2. Then, the pusher 32 pushes one or more apple pieces to the outlet 21 each time, thus achieving quantitative feeding of one or more apple pieces each time.

[0067] Furthermore, the height of the pushing part 321 of the push table 32 of this utility model is adapted to the height of the opening 11 from the bottom of the inner end of the outer shell 4. When the sliding adjustment component 6 is adjusted, a corresponding size of pushing part 321 is required so that the pushing part 321 of the push table 32 can slide along the second channel 2 and block the opening 11.

[0068] 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.
