Description

Technical Field

[0001] The present invention belongs to the technical field of livestock breeding, and particularly relates to a precise feeding trough and a feeding system based on scientific breeding of dairy cows. Background Art

[0002] With the transformation of dairy cow breeding towards large-scale, the feed intake of dairy cows is also scientifically controlled, so precise feeding needs to be implemented.

[0003] In the prior art, regarding the precise feeding of dairy cows, the key lies in the feeding trough. In large-scale dairy cow breeding, the feeding trough needs to achieve precise weighing of feed to monitor the daily feed intake of individual dairy cows. Usually, it is a fixed structure with an open top, and a weighing module is arranged at the bottom of the feeding trough to ensure the weighing accuracy. Usually, a fixed amount of feed, such as 30 kg, is put into the feeding trough before each feeding, but there will eventually be leftovers in the feeding trough, and this part of the forage is usually used as bedding or compost. Therefore, it is necessary to clean the feeding trough after each feeding, and this process involves water washing. For a fixed-structure feeding trough, its cleaning is time-consuming and laborious, and it is not conducive to the construction of intelligent breeding, with poor practicability. Summary of the Invention

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] Please refer to together Figure 1 and Figure 2, the precision feeding trough based on scientific dairy farming provided by the present invention will now be described. The precision feeding trough based on scientific dairy farming includes a fixed base 10, a first weighing support 20, a hopper 30, a telescopic structure 40, and a controller. The fixed base 10 has a horizontally arranged platform, and a vertical gantry frame 11 is provided on the top of the platform. There are two first weighing supports 20, and the two first weighing supports 20 are arranged on the platform at intervals along the width direction of the vertical gantry frame 11. The hopper 30 is rotatably connected to the two first weighing supports 20, and an identification module 33 is provided on the hopper 30. One end of the telescopic structure 40 is rotatably connected to a second weighing support 50 provided on the vertical gantry frame 11, and the other end is rotatably connected to the hopper 30. The telescopic structure 40 can drive the vertically arranged hopper 30 to pitch and turn to an open position with an inclined downward setting during cleaning. When the hopper 30 is vertically arranged, the weights of the hopper 30 and the telescopic structure 40 act entirely on the two first weighing supports 20 and the second weighing support 50.

[0048] Regarding the precision feeding trough based on scientific dairy farming provided in this embodiment, its working principle is as follows.

[0049] Before feeding, the telescopic structure 40 adjusts the hopper 30 to a vertical setting, that is, the open end of the hopper 30 faces upward, ensuring that the gravity of the hopper 30 and the telescopic structure 40 acts entirely on the two first weighing supports 20 and the second weighing support 50. The two first weighing supports 20 and the second weighing support 50 jointly and precisely monitor the weights of the hopper 30 and the telescopic structure 40. When there is no feed in the hopper 30, the controller will obtain an initial value at this time. When feed is added to the hopper 30, the change values of the two first weighing supports 20 and the second weighing support 50 are the initial weights of the feed. During the feeding process of the cows, there may be a situation of mobile feeding, that is, the amount of feed intake each time comes from two or more different precision feeding troughs based on scientific dairy farming. When a cow is in one of the precision feeding troughs based on scientific dairy farming, the identification module 33 can identify the ear tag of the cow, and then accurately monitor the feed intake of the cows in the precision feeding trough based on scientific dairy farming according to the reduction of the feed after the cow leaves.

[0050] After feeding, there may be some remaining feed or unpalatable feed components in the hopper 30. At this time, the feed is also mixed with the saliva of the cows, and the feed adheres to the inner wall of the hopper 30 and needs to be washed with water. At this time, the telescopic structure 40 can be used to drive the hopper 30 to turn, so that its open end is inclined downward, and thus the cleaning process can ensure the timely pouring out of the cleaning water, improving the convenience of cleaning.

[0051] The precise feeding trough based on scientific dairy farming provided in this embodiment, compared with the prior art, the two first weighing supports 20 provided on the fixed base 10 can ensure the rotational connection of the feeding hopper 30, while the second weighing support 50 on the vertical gantry frame 11 can ensure the rotational connection of the telescopic structure 40. The two first weighing supports 20 and the two second weighing supports 50 can cooperate with the telescopic structure 40 to enable the hopper 30 to be vertically arranged, and at the same time, all the weight acts on the two first weighing supports 20 and the second weighing support 50, ensuring the precise monitoring of the reduced amount of feed and facilitating the scientific feeding of dairy cows. Moreover, the telescopic structure 40 can also drive the hopper 30 to pitch and flip. When the hopper 30 pitches and flips downward, the opening of the hopper 30 can be inclined downward, which is convenient for the export of the cleaning water during the cleaning process of the hopper 30, improving the convenience. Through the cooperation of the telescopic structure 40 with the two first weighing supports 20, the second weighing support 50 and the flipable hopper 30, while ensuring the weighing accuracy, the cleaning convenience of the hopper 30 is guaranteed, and the practicability is strong.

[0052] In some embodiments, the above-mentioned vertical gantry frame 11 may adopt a structure such as Figure 2 shown. Refer to Figure 2 , the vertical gantry frame 11 includes two spaced-apart columns. The second weighing support 50 is located on one of the columns.

[0053] Regarding the vertical setting of the vertical gantry frame 11, therefore, the second weighing support 50 is located on the vertical gantry frame 11, which can ensure that the hopper 30 is flipped to a vertical setting, thereby ensuring the accuracy of feed weight monitoring.

[0054] In this embodiment, refer to Figure 3 , regarding the second weighing support 50, it may include a vertical sliding seat 51. The vertical sliding seat 51 is slidably connected to the limiting slide rail 13 provided on the column. A sealing cover 52 is provided at the bottom of the chute of the vertical sliding seat 51, so that the vertical sliding seat 51 can only move downward and cannot move obliquely upward. A first pressure sensor 53 is provided at the bottom end of the vertical sliding seat 51. Correspondingly, a support platform 12 is provided on the column. The support platform 12 is located below the vertical sliding seat 51 and clamps the first pressure sensor 53 together with the vertical sliding seat 51. A limiting groove for embedding the pressure sensor may be provided on the support platform 12.

[0055] In some embodiments, the above-mentioned hopper 30 may adopt a structure such as Figure 1 and Figure 2 shown. Refer to Figure 1 and Figure 2 , the hopper 30 is provided with a notch 31 on the side wall close to and corresponding to the vertical gantry frame 11, which can allow the head of the dairy cow to extend into it. The setting of the notch 31 can adapt to the feeding habits of dairy cows and avoid interference between the neck of the dairy cow and the hopper 30.

[0056] In some embodiments, the above weighing support can adopt structures such as Figure 1 and Figure 5 shown. Referring to Figure 1 and Figure 5 , two first weighing supports 20 are respectively set as the first support and the second support.

[0057] Specifically, the first support and the telescopic structure 40 are on the same side.

[0058] Specifically, the second support is on the other side of the hopper 30 and is rotatably connected to the hollow rotating shaft 32 provided on the hopper 30. A through hole is provided on the side wall of the hollow rotating shaft 32. An annular cavity is provided in the second support around the hollow rotating shaft 32. A plurality of partition plates 21 are annularly provided in the annular cavity, and each partition plate 21 divides the annular cavity to form sub-cavities that can be respectively communicated with the through hole.

[0059] In this embodiment, for a specific implementation manner of the first support and the second support, both can include two guiding and limiting columns 24 fixedly provided on the fixed base 10. An articulated seat 25 is clamped between the guiding and limiting columns 24, and a second pressure sensor 26 is provided between the articulated seat 25 and the fixed base 10. The top end of each guiding and limiting column 24 has a limiting cap, and the limiting cap abuts against the articulated seat 25.

[0060] The difference between the first support and the second support is only the difference in the articulated seat 25.

[0061] Specifically, the precision feeding trough based on scientific dairy farming further includes a self-cleaning module 70. The self-cleaning module 70 corresponds to at least two sub-cavities, and the self-cleaning module 70 can flush and dry the inside of the hopper 30 after the hopper 30 rotates downward from the vertical pitch.

[0062] In the second support, the annular cavity is divided into a plurality of sub-cavities by a plurality of partition plates 21. Two of the sub-cavities are respectively connected to the self-cleaning module 70. This structure can ensure the linkage between the self-cleaning structure and the flipping action of the hopper 30, so as to ensure that the cleaning mode is triggered during the flipping process of the hopper 30, and then realize the automatic cleaning and drying work of the hopper 30, saving manpower and material resources. Of course, it also avoids accidentally triggering the cleaning mode when the hopper 30 is vertically arranged or during the dairy feeding process, causing fright to the cows.

[0063] In some embodiments, the above self-cleaning module 70 can adopt structures such as Figure 1 , Figure 2 , Figure 5 and Figure 6 shown. Referring to Figure 1 , Figure 2 , Figure 5 and Figure 6, the self-cleaning module 70 includes a U-shaped fixing pipe 71, a connecting pipe 72, an air pump 73, and a water pump 74. The U-shaped fixing pipe 71 is arranged around the notch 31 and is located on the inner wall surface of the hopper 30. A plurality of injection ports are arranged on the U-shaped fixing pipe 71. One end of the connecting pipe 72 communicates with the U-shaped fixing pipe 71, and the other end communicates with the hollow rotating shaft 32. The air pump 73 communicates with one of the sub-chambers through a high-pressure hose. The water pump 74 communicates with one of the sub-chambers through a high-pressure hose, and the water pump 74 can be placed in the water tank.

[0064] The U-shaped fixing pipe 71 is arranged around the notch 31, which can thicken the edge of the notch 31, avoid scratching the neck of the dairy cow due to the relatively thin side wall of the hopper 30, and ensure the safety effect. At the same time, after the hopper 30 is turned over, the side wall with the U-shaped fixing pipe 71 will move above the hopper 30. At this time, the water or gas ejected from the U-shaped fixing pipe 71 through each injection port can cover the entire inner wall of the hopper 30, thereby ensuring the cleaning effect of the hopper 30.

[0065] Specifically, during the process of the hopper 30 pitching and turning downward, it first passes through the sub-chamber corresponding to the air pump 73 and then reaches the sub-chamber corresponding to the water pump 74. In this process, it is necessary to make the through-hole of the hollow rotating shaft 32 first pass through the sub-chamber corresponding to the air pump 73 (set as the first chamber 22) and then reach the sub-chamber corresponding to the water pump 74 (set as the second chamber 23).

[0066] For a specific implementation manner of the hollow rotating shaft 32 and the second support, the hopper 30 can be turned from the vertical setting to the open-mouth obliquely downward setting by an angle of 110°. When the hopper 30 is in the vertical setting, its through-hole can be arranged along the penetration direction of the vertical gantry frame 11 frame opening and facing the vertical gantry frame 11. At this time, the plane where the axis of the through-hole is located is set as the first plane. The angle between the first chamber 22 and the first plane is between 90° and 100°, and the angle between the second gun and the first plane is between 100° - 110°. This can ensure that when the hopper 30 is turned to a position between 90° and 100°, high-pressure gas blowing is triggered. Of course, high-temperature steam can also be used; when the hopper 30 is turned to a position between 100° - 110°, high-pressure water cleaning is triggered. At this time, the open mouth of the hopper 30 is obliquely downward, which can ensure that the cleaning water mixed with the remaining feed is timely discharged from the hopper 30.

[0067] In this embodiment, regarding the connection between the hollow rotating shaft 32 and the second support, a sealed bearing needs to be set.

[0068] In this embodiment, during the process of the hopper 30 being turned from the vertical setting, it can directly briefly cross the first chamber 22 and go straight to the second chamber 23 and stay, that is, first perform water washing. After the water washing is completed, it can be pitched upward to correspond to the first chamber 22 and stay. At this time, the inner wall of the hopper 30 is dried by high-speed air flow.

[0069] In some embodiments, the above U-shaped fixing tube 71 can be of the structure as shown in Figure 1 . Refer to Figure 1 . Set the side wall of the hopper 30 where the U-shaped fixing tube 71 is located as the first side wall, and the first side wall has three adjacent side walls. Each spray port is arranged facing three side walls adjacent to the first side wall.

[0070] After the hopper 30 is turned over, the gas and cleaning water ejected through the U-shaped fixing tube 71 will impact on the side walls adjacent to the first side wall, avoiding waste of cleaning water or ineffective cleaning. And after the hopper 30 is turned over, the first side wall will be located at the top of the hopper 30. At this time, the gravity of the cleaning water after ejection can also be converted into partial kinetic energy, thereby ensuring the flushing of other side walls and ensuring the cleaning effect.

[0071] In some embodiments, the above vertical gantry frame 11 can be of the structure as shown in Figure 2 . Refer to Figure 2 . A neck clamp 60 is provided in the frame opening of the vertical gantry frame 11.

[0072] During the feeding process of the cows, the heads of the cows need to pass through the vertical gantry frame 11 first and then through the notch 31 of the hopper 30 and extend into the hopper 30. When it comes to the feeding process of the feed in the hopper 30, the amount of feed is dynamic. At this time, in order to prevent the cows from eating during this stage, the cows can be intercepted by the neck clamp 60.

[0073] Regarding the structure of the neck clamp 60, the prior art can also be adopted and will not be elaborated here.

[0074] Based on the same inventive concept, the present invention also provides a feeding system, including the above-mentioned precision feeding trough based on scientific cow breeding and a feeding unit 80. There are multiple precision feeding troughs based on scientific cow breeding, and each precision feeding trough based on scientific cow breeding is arranged in sequence. The feeding unit 80 has a plurality of feed delivery ends that can correspond to each precision feeding trough based on scientific cow breeding one by one, and can quantitatively feed feed into each precision feeding trough based on scientific cow breeding.

[0075] Compared with the prior art, the feeding system provided in this embodiment can ensure quantitative feeding into the hoppers 30 of each precision feeding trough based on scientific cow breeding through the arranged feeding unit 80. And multiple precision feeding troughs based on scientific cow breeding can ensure accurate monitoring of the intake of each cow. At the same time, the feeding system can achieve automatic cleaning through the precision feeding trough based on scientific cow breeding, saving manpower and material resources and having strong practicability.

[0076] In some embodiments, the above feeding system can be of the structure as shown in Figure 6 . Refer to Figure 6, the feeding system further includes a discharge long trough 90, and the discharge long trough 90 can collect the remaining feed poured out from each precise feeding trough based on scientific dairy farming. The discharge long trough 90 can ensure the collection of the discharged cleaning water and the remaining feed, facilitating subsequent processing.

[0077] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
