In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0025] As attached Figure 1 To be continued Figure 7 As shown: This embodiment provides an auxiliary feed box and feed line for raising breeding chickens, including an auxiliary feeding device 1, a feed box adjustment frame 2 installed on the auxiliary feeding device 1, a feed box 11 inside the auxiliary feeding device 1, an even number of height adjustment columns 12 installed on the feed box 11, a feed cover 13 installed on the feed box 11, an even number of fixed frames 21 inside the box adjustment frame 2, a pipe frame 22 fixed on the fixed frames 21, and a box transverse sliding rod 23 connecting the even number of fixed frames 21.

[0026] Furthermore, at least two fixed platforms 21 are provided, which are fixed to the roof of the farm to form a suspension of the auxiliary feeding equipment 1 in conjunction with the transverse shift rod 23 of the frame box, and facilitate the adjustment and displacement of the auxiliary feeding equipment 1 according to the subsequent breeding chicken farming needs.

[0027] The feed bin 11 contains a box body 111. Support plates 112 are fixed on both sides of the outer wall of the box body 111. Side clamping rod sleeves 113 are provided below the support plates 112. A box cover frame 115 is nested around the opening of the box body 111. A feed supply device 114 is connected to the bottom of the box body 111. An even number of threaded fixing columns 121 are provided inside the height adjustment column 12. Threaded adjustment rods 122 are connected between the even number of threaded fixing columns 121. A box cover 131 is provided inside the feed cover 13. An even number of diversion pipes 132 are fixed on the box cover 131. A feed transmission pipe 133 is fixed at the end of the diversion pipe 132.

[0028] Furthermore, the support plate 112 is mainly used for support when the box cover 131 is covered, and at the same time, it works with the lower side clamping rod sleeve 113 to form a fixation, so that the two are fixed to the outside of the box body 111, and assist in completing the coordination of the other equipment.

[0029] Furthermore, each of the threaded retaining columns 121 has threads, which can be screwed together with the threaded adjusting rod 122 to achieve synchronous adjustment within the threaded retaining column 121, thereby adjusting the height of the material box 11 and facilitating a suspended state during movement.

[0030] Furthermore, the feed transmission pipe 133 is mainly used for feed supply, while at least two branch pipes 132 installed at the end are used for the even distribution and delivery of feed, so that the feed supply process will not continuously exert downward pressure on the structure on the support plate 112.

[0031] The box body 111 has an inner cavity 1111, a material guiding device 1112 is installed in the inner cavity 1111, a conical lower cavity 11111 is formed in the inner cavity 1111, a first guide plate 11112 is fixed in the conical lower cavity 11111, and a second guide plate 11113 is arranged below the first guide plate 11112.

[0032] Furthermore, the upper part of the inner cavity 1111 is square, while the lower part is composed of a conical lower cavity 1111. The middle connecting position is separated by a feed guiding device 1112, which allows feed to be supplied after separation and closes after feeding is completed.

[0033] The side clamping rod sleeve 113 has a sleeve hole 1131, and several sets of in-hole rubber ball groups 1132 are fixed on the inner wall of the sleeve hole 1131. The feed supply device 114 is provided with an outer connecting sleeve 1141, and a feed pipe 1142 passes through the outer connecting sleeve 1141. A one-way baffle valve 1143 is installed in the center of the outer connecting sleeve 1141.

[0034] Furthermore, the sleeve hole 1131 is mainly used for the nesting of the frame box transverse moving rod 23, while the several sets of in-hole rubber balls 1132 arranged in a straight line inside the sleeve hole 1131 mainly serve to fix and increase the resistance on the surface of the frame box transverse moving rod 23, so as to prevent displacement when not subjected to external force.

[0035] Furthermore, the one-way baffle valve 1143 is mainly used to separate the feeding of the main feed line and the auxiliary feeding equipment 1 set in the middle section.

[0036] Furthermore, the feed pipe 1142 has several evenly distributed feed trays. The feed supplied is loaded into the feed trays through the feed holes opened on the pipe, allowing the breeder chickens to eat.

[0037] The material guiding device 1112 is equipped with a horizontal plate 11121. A material drop groove 11122 is opened on the surface of the horizontal plate 11121. A hollow inclined baffle 11123 is fixed on the horizontal plate 11121. Side slides 11124 are opened in both the hollow inclined baffle 11123 and the horizontal plate 11121. An inclined plate slot 11125 is opened on the inner wall of the hollow inclined baffle 11123. A movable baffle 11126 is nested between the side slides 11124. A hinged support 11127 is fixed on the inner wall of the movable baffle 11126. A floating ball 11128 is installed at the end of the hinged support 11127.

[0038] Furthermore, the horizontal plate 11121 mainly serves as a partition for the inner cavity 1111 of the box, and a material drop chute 11122 is opened on its surface so that the material drop chute 11122 can be opened or closed according to the height of the material level with the cooperation of the movable baffle 11126 and the floating ball 11128.

[0039] Furthermore, both the perforated inclined baffle 11123 and the horizontal plate 11121 are perforated, but the perforations are filled by the movable baffle 11126 installed between the side slides 11124. When the feed supply is completed and the inner cavity 1111 of the box is empty, the feed chute 11122 is closed.

[0040] Furthermore, the movable baffle 11126 is mainly driven by the floating ball 11128 at the end of the hinged support 11127 fixed on the inner wall. The floating ball 11128 is filled with feed during feeding and forms a floating state, thereby pulling the movable baffle 11126 up and opening the feed chute 11122 to complete the feeding. As the feed decreases, the floating ball 11128 falls down, completing the closure of the feed chute 11122.

[0041] Furthermore, the main feed bin is installed at the front and rear of the farm, and then a separate feed transmission pipe 133 is connected to it to supply feed to the auxiliary feeding equipment 1, while the feed supply pipe at the front end is supplied by a drive electric auger.

[0042] The specific working principle is as follows: This invention suspends the feed box adjustment frame 2 from the ceiling of the farm. A horizontal shifting rod 23 passes through the frame and enters the side clamping rod sleeve 113 of the auxiliary feeding device 1. The rubber ball assembly 1132 inside the sleeve hole 1131 secures the surface of the horizontal shifting rod 23, thus displacing the auxiliary feeding device 1 to the designated position. During feeding, the feed transmission pipe 113 connected to the main feed box independently supplies feed to the auxiliary feeding device 1, while the main feed box is driven by an electric auger to complete the transmission through the front-end feeding pipe. After passing through the feed transmission pipe 133, the feed falls from the diversion pipe 132 on the box cover 131 into the inner cavity 1111 of the box body 111. As the amount of feed increases... The floating ball 11128 in the feeding device 1112 rises and pulls the movable baffle 11126 between the horizontal plate 11121 and the hollowed-out inclined baffle 11123. The hinged support 11127 rises along with the inclined plate slot 11125. Finally, the feed chute 11122 unfolds and feeds into the first guide plate 11112 in the conical lower cavity 11111. Then, with the cooperation of the second guide plate 11113, the feed falls in front of the opening side of the current baffle valve 11142, completing the feed supply of the feed pipe 1142. This satisfies the synchronous feeding of the front and rear feed trays, effectively avoiding the fighting, stress and trampling caused by the rear breeder chickens waiting, and improving the uniformity of feeding.
