Description

Technical Field

[0001] The present application relates to the technical field of animal husbandry, and specifically discloses an automatic feeding device for a pig farm. Background Art

[0002] With the scientific, systematic and large-scale development of the pig farming industry, various equipment has emerged in the pig farming process, which has continuously improved the efficiency of pig farming. Feeding devices are an indispensable equipment in the pig farming industry.

[0003] The traditional feeding device is usually connected to the top of the pig trough through a feeding pipe, and pig feed is added to the pig trough by controlling the opening of a valve. Although this type of feeding method is convenient and fast, each feeding pipe needs to be equipped with a valve for control, resulting in a high overall cost of the feeding device, a high number of failures and maintenance, and the valve is usually located at the end of the feeding pipe, that is, above the pig trough, which is easily polluted by the environment in the pig house and damaged, further increasing the subsequent maintenance cost. Therefore, in view of this, the inventor provides an automatic feeding device for a pig farm to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problem that a traditional feeding device needs to be equipped with a valve on each feeding pipeline, which increases the equipment cost and maintenance cost.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides an automatic feeding device for a pig farm, comprising:

[0006] Feed pipe;

[0007] A material distribution box is connected to the end of the feed pipe, and a plurality of partitions are arranged in the material distribution box, and the partitions divide the bottom of the material distribution box into a plurality of cavities;

[0008] A plurality of feeding pipes are respectively connected to the bottom of each cavity and extend to the top of each pig trough;

[0009] A plurality of plungers are respectively located in each cavity, and one end of each plunger is slidably connected to each feeding pipe, and a feeding hole is connected between the side wall and the bottom of the plunger;

[0010] The driving mechanism drives each plunger to slide vertically in the cavity.

[0011] The principles and effects of this basic solution are:

[0012] Compared with the prior art, the utility model can control the vertical movement of each plunger by controlling the start of the power part, so that the feed hole is located in the feeding pipe or outside the feeding pipe. When the feed port is completely located inside the feeding pipe, the plunger completely blocks the feeding pipe, thereby closing the pig feed supply to the pig trough. When the top of the feed hole is located outside the feeding pipe and the bottom is located inside the feeding pipe, the cavity in the distribution box can be connected with the feeding pipe, so that pig feed is supplied to the feeding pipe, that is, the pig feed is supplied to the pig trough, thereby realizing automatic feeding of pig feed, and the pig feed is intermittently supplied during the feeding process, which can effectively avoid the problem of pig feed accumulation and jamming. In the whole process, the feeding process control can be completed only by starting and stopping the power part, which is not only convenient to control, but also has low equipment cost and maintenance cost.

[0013] Furthermore, the driving mechanism comprises:

[0014] Power parts;

[0015] An eccentric shaft, driven to rotate by the power member and located above the partition;

[0016] A plurality of connecting sleeves are rotatably connected to the side walls of the eccentric shaft and are respectively located directly above the plungers;

[0017] A plurality of connecting rods are respectively hinged between the connecting sleeve and the plunger located in the same vertical plane.

[0018] The position of the connecting sleeve can be changed by driving the eccentric shaft to rotate through the power member, and then the plunger can be driven to move vertically through the connecting rod, and the structure is compact.

[0019] Furthermore, it also includes a conversion mechanism provided between the power member and the eccentric shaft, and the conversion mechanism includes:

[0020] A driving wheel is coaxially connected to the output shaft of the power member, and a notch is provided on the driving wheel, and a ratchet is hinged at the notch;

[0021] The driven wheel is coaxially connected to the end of the eccentric shaft, and the side wall of the driven wheel is provided with a first transition surface adapted to the outer wall of the driving wheel and a second transition surface adapted to the pawl.

[0022] The ratchet pawl cooperates with the driven wheel so that the driving wheel can drive the driven wheel to rotate, and when the driven wheel rotates under the gravity of the eccentric shaft, it will not drive the driving wheel to rotate, so that after the power part stops, the eccentric shaft is located at the lowest point, that is, the plunger is located at the lowest point, so that the plunger blocks each feeding pipe.

[0023] Furthermore, there are at least two notches and two pawls, which are symmetrically arranged along the center of the driving wheel. This arrangement can achieve a force balance effect.

[0024] Furthermore, the power member is located outside the material distribution box, and the outer side wall of the power member is provided with a fixing seat for fixing the power member and an end cover for protecting the driving wheel and the driven wheel. The end cover plays a protective role on the driving wheel and the driven wheel.

[0025] Furthermore, it also includes a plurality of guide plates obliquely arranged in the feed distribution box, the top of the guide plate is located directly below the end of the feed pipe, and the bottom of the guide plate is located directly above the partition. The guide plate guides and divides the flow of feed.

[0026] Furthermore, the spacing between the tops of the guide plates is the same, which increases the uniformity of feed segmentation. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] An automatic feeding device for a pig farm, for example Figure 1As shown, it includes the following structures:

[0034] Feed pipe 1: The feed pipe 1 is connected to a tank or a chamber for storing feed, and the feed pipe 1 is controlled by a valve to supply pig feed.

[0035] Distribution box 2: A feed inlet is arranged on the top of the distribution box 2, and the distribution box 2 is connected with the end of the feed pipe 1 through the feed inlet. Figure 2 As shown, three partitions 9 are provided in the distribution box 2, and the three partitions 9 divide the bottom of the distribution box 2 into four cavities. The bottom of each cavity is provided with an inclined surface to prevent pig feed from accumulating at the bottom of the cavity. Three guide plates 8 are inclinedly arranged in the distribution box 2 above the partitions 9, and the spacing between the tops of the guide plates 8 is the same. The top of the guide plate 8 is located directly below the end of the feed pipe 1, and the bottom of the guide plate 8 is located directly above the partition 9.

[0036] Four feeding pipes 3: The feeding pipes 3 are respectively connected to the lowest point of the inclined surface at the bottom of each cavity. The feeding pipes 3 extend to the top of each pig trough and are provided with a hopper 4.

[0037] Four plungers 10: The plungers 10 are respectively located in each cavity, and the bottom ends of the plungers 10 are respectively slidably connected in each feeding pipe 3, and a feeding hole is connected between the side wall and the bottom of the plunger 10.

[0038] Driving mechanism: The driving mechanism is used to drive each plunger 10 to slide vertically in the cavity, and specifically includes structures such as a power piece 5, a conversion mechanism, an eccentric shaft 12, a connecting sleeve 13 and a connecting rod 11, wherein the power piece 5 can be a servo motor and is arranged on the outside of the distribution box 2, and the outer side wall of the power piece 5 is provided with a fixing seat 6 for fixing the power piece 5; the eccentric shaft 12 is rotatably connected in the distribution box 2 and is located above the partition 9, the connecting sleeves 13 are rotatably connected to the side walls of the eccentric shaft 12 and are respectively located directly above each plunger 10, and the connecting rod 11 is respectively hinged between the connecting sleeve 13 and the plunger 10 located in the same vertical plane, the conversion mechanism includes a driving wheel 14 and a driven wheel 15, and the side wall of the distribution box 2 is provided with an end cover 7 for protecting the driving wheel 14 and the driven wheel 15, and the driving wheel 14 is coaxially connected to the output shaft of the power piece 5, such as Figure 3 As shown, at least two notches are symmetrically provided on the center of the driving wheel 14, and a pawl 16 is hinged at each notch. The driven wheel 15 is coaxially connected to the end of the eccentric shaft 12, and the side wall of the driven wheel 15 is provided with a first transition surface adapted to the outer wall of the driving wheel 14 and a second transition surface adapted to the pawl 16.

[0039] During the implementation of this embodiment, the valve is first opened, and the feeding pipe 1 is used to fill the distribution box 2 with pig feed. The pig feed contained in the distribution box 2 is the sum of the feed required by all pig troughs. When feeding is needed, the motor is started, and the driven wheel 15 is driven to start by the pawl 16 on the driving wheel 14, thereby driving the eccentric shaft 12 to rotate, so that each plunger 10 can be controlled to move vertically, so that the feeding hole is located in the feeding pipe 3 or outside the feeding pipe 3. When the feeding port is completely located inside the feeding pipe 3, the plunger 10 completely blocks the feeding pipe 3, thereby closing the pig feed supply to the pig trough. When the top of the feeding hole is located outside the feeding pipe 3 and the bottom is located inside the feeding pipe 3, the volume cavity in the distribution box 2 and the feeding pipe 3 can be connected. The feeding pipe 3 is connected, so that pig feed is supplied to the feeding pipe 3, that is, pig feed is supplied to the pig trough, so that automatic feeding of pig feed can be realized, and the pig feed is supplied intermittently during the feeding process, which can effectively avoid the problem of pig feed accumulation and jamming. In the whole process, the feeding process control can be completed only by starting and stopping the power part 5, which is not only convenient to control, but also has low equipment cost and maintenance cost. After a single feeding is completed, the power part 5 is closed, and the eccentric shaft 12 rotates downward to the lowest point under the action of its own gravity, so that the plunger 10 is at the lowest point, so that the plunger 10 blocks each feeding pipe 3, and then opens again through the valve, and uses the feeding pipe 1 to fill the distribution box 2 with pig feed.
