Technical Field

[0001] The invention relates to the field of breeding, and in particular to a chick-brooding heat-insulating umbrella. Background Art

[0002] Brooding is an important stage in chicken farming. Since chicks are weak and have low resistance to cold and disease, they are very susceptible to low temperatures and become sick. Therefore, appropriate equipment is needed to artificially create an environment suitable for the growth of chicks.

[0003] At present, the most common equipment is the brooder house. By installing a heat preservation mechanism in the brooder house, the environment in the brooder house is ensured to be in a relatively constant range. However, due to the large size and complex structure of the brooder house, it is inconvenient to use and move, and it is also very troublesome to clean during use. For this reason, this scheme proposes a brooder heat preservation umbrella. Summary of the invention

[0007] The outer peripheral movable sleeve of the fixing tube is provided with a mounting ring, a heating lamp is installed on the bottom surface of the mounting ring, a plurality of fixing rods are fixed on the bottom surface of the mounting ring, and a connecting rod is hingedly connected to the outer wall of one side of the fixing rod, and the other end of the connecting rod is hingedly connected to one of the umbrella ribs;

[0008] An adjusting cover is sleeved on the outer periphery of the fixing tube, the adjusting cover is located above the top of the umbrella body, and a plurality of movable rods are fixed to the inner wall of the top of the adjusting cover, the bottom of the movable rods penetrates the umbrella body and is fixed to the top of the mounting ring, a knob switch connected to the heating lamp is installed on the outer periphery of the adjusting cover, and a locking mechanism for locking the position of the adjusting cover is installed on the top of the adjusting cover;

[0009] A material receiving hopper is installed on the top of the fixed tube through an elastic member, and a material holding assembly is installed on the bottom of the fixed tube. The material holding assembly includes a bottom plate fixed to the bottom of the fixed tube and a fixed ring movably mounted on the outer periphery of the bottom plate, and a plurality of fixed plates located below the bottom plate are fixed to the inner ring of the fixed ring. The fixed rod passes through the bottom plate and is fixedly connected to the fixed plate, and a plurality of discharge ports are opened at the outer bottom of the fixed tube.

[0010] Through the above technical solution, not only the structure is simple, but also it is very convenient to open and fold the umbrella body. At the same time, the residual feed in the material holding component can be poured out when the umbrella body is folded, which is convenient for the user's subsequent cleaning.

[0011] As a further improvement of the above scheme, the elastic member includes a feed pipe fixed at the bottom of the receiving hopper and a first spring movably mounted on the outer periphery of the feed pipe, the feed pipe is coaxially arranged with the receiving hopper, and the bottom of the feed pipe is movably mounted on the inner side of the fixed tube, the top of the first spring is fixedly connected to the bottom surface of the receiving hopper, and the bottom of the first spring is fixedly connected to the top surface of the fixed tube.

The inner ring of the annular tube is fixed to the outer periphery of the fixed tube by a fixed shaft, and a plurality of air outlet holes are opened on the bottom surface of the annular tube.

[0024] Through the above technical solution, the air in the ring tube is ejected from the air outlet and blown onto the top of the bottom plate, thereby blowing away the feed remaining on the top surface of the bottom plate to prevent the feed from remaining on the top surface of the bottom plate.

[0025] As a further improvement of the above scheme, the number of the gas distribution components is 2 to 3, and the gas distribution components include an air cylinder fixed to the outer periphery of the fixed tube, a piston plate arranged in the air cylinder and a piston rod fixed to the top of the piston plate, the other end of the piston rod is fixed to the bottom surface of the mounting ring, and a connecting pipe is installed at the bottom of the air cylinder, and the other end of the connecting pipe is connected to the ring pipe.

[0027] As a further improvement of the above solution, the bottom surface of the annular tube is flush with the top surface of the discharge port, and the fixing rod is located inside the annular tube.

[0028] The above technical solution can prevent the annular tube from blocking the discharge of feed from the discharge port.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. Through the cooperation between the umbrella body, ribs, fixing tubes and heating lamps, a space for the chicks to grow can be formed after the umbrella body is opened. The heating lamp is used to heat the internal space of the umbrella body, and the part of the ribs protruding from the outside of the umbrella body is in contact with the ground, so that there is a gap between the bottom of the umbrella body and the ground, which is convenient for the chicks to enter and exit.

[0031] 2. Through the coordination among the adjustment cover, the mounting ring and the locking mechanism, the umbrella body can be conveniently opened and folded, which is convenient for the breeders to use. At the same time, the mounting ring is used in conjunction with the feed holding assembly, so that the fixing ring can be driven to descend while the umbrella body is folded, so that the feed on the bottom plate loses the enclosure of the fixing ring and can automatically fall from the bottom plate, thereby achieving the purpose of facilitating the removal of residual feed while folding the umbrella body.

[0032] 3. Through the setting of the cleaning mechanism, the air in the cylinder can be pressed into the ring tube and then sprayed out when the umbrella body is folded, so that the feed remaining on the bottom plate can be blown away to avoid the feed remaining on the top surface of the bottom plate.

[0042] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0043] Embodiment 1:

[0044] Please combine Figure 1 - Figure 7A brooding and heat-insulating umbrella of the present embodiment comprises a fixing tube 6, a plurality of ribs 2 hinged on the outer periphery of the fixing tube 6, and an umbrella body 1 fixed on the surfaces of the plurality of ribs 2. The ends of the ribs 2 extend beyond the coverage of the umbrella body 1. An access passage is formed between the bottom of the umbrella body 1 and the bottom of the ends of the ribs 2. When the umbrella body 1 is opened, the inner side thereof is an activity space for the chicks, and the setting of the access passage is to facilitate the entry and exit of the chicks.

[0045] The peripheral movable sleeve of the fixing tube 6 is provided with a mounting ring 15, and a heating lamp 16 is installed on the bottom surface of the mounting ring 15. When the heating lamp 16 is turned on, the space inside the umbrella body 1 can be heated, so that the temperature is more suitable for the growth of the chicks.

[0046] A plurality of fixing rods 12 are fixed to the bottom surface of the mounting ring 15, and a connecting rod 14 is hinged to the outer wall of one side of the fixing rod 12, and the other end of the connecting rod 14 is hinged to one of the ribs 2. A limiting sleeve 13 is provided on the outer peripheral movable sleeve of the fixing rod 12, and the outer periphery of the limiting sleeve 13 is fixedly connected to the outer periphery of the fixing tube 6. When the mounting ring 15 moves up and down, it can drive the umbrella body 1 to open or close.

[0047] An adjusting cover 3 is sleeved on the outer periphery of the fixing tube 6. The adjusting cover 3 is located above the top of the umbrella body 1, and a plurality of movable rods 17 are fixed to the inner wall of the top of the adjusting cover 3. The bottom of the movable rod 17 passes through the umbrella body 1 and is fixedly connected to the top of the mounting ring 15. A knob switch 4 connected to the heating lamp 16 is installed on the outer periphery of the adjusting cover 3. When the adjusting cover 3 moves upward, the mounting ring 15 moves upward, the ribs 2 open outward, and the umbrella body 1 opens accordingly. Conversely, when the adjusting cover 3 is pressed downward, the ribs 2 are driven to fold, and the umbrella body 1 also folds accordingly.

[0048] A locking mechanism for locking the position of the adjusting cover 3 is installed on the top of the adjusting cover 3, and the locking mechanism includes a positioning column 9, a second spring movably sleeved on the top of the positioning column 9 and a mounting block 8. The bottom of the mounting block 8 is fixedly connected to the top surface of the adjusting cover 3, and a stopper is fixed to the end of the positioning column 9 away from the fixed tube 6, one end of the second spring is fixedly connected to the stopper, and the other end of the second spring is fixedly connected to the mounting block 8. Two positioning holes 10 that coincide with the positioning column 9 are provided on the outer periphery of the fixed tube 6, and the two positioning holes 10 are arranged from top to bottom. The arrangement of the second spring enables the positioning column 9 to always abut against the outer wall of the fixed tube 6 in the absence of external force, so that when the positioning column 9 moves to the initial position of the positioning hole 10, the positioning column 9 will be stuck in the positioning hole 10, and the adjusting cover 3 is locked and cannot move further. After one end of the positioning column 9 is pulled out to the outside of the positioning hole 10, the adjusting cover 3 can continue to be moved.

[0049] The adjusting cover 3 is a truncated cone-shaped shell, and the top of the adjusting cover 3 is sealed. The bottom diameter of the adjusting cover 3 is larger than the top diameter, so that when the umbrella body is folded, it can be conveniently put on the top of the umbrella body 1.

[0050] The top of the fixed tube 6 is provided with a receiving hopper 5 through an elastic member, and the bottom of the fixed tube 6 is provided with a material holding assembly, which includes a bottom plate 19 fixed to the bottom of the fixed tube 6 and a fixed ring 11 movably sleeved on the outer periphery of the bottom plate 19, and the inner ring of the fixed ring 11 is fixed with a plurality of fixed plates 18 located below the bottom plate 19, a fixed rod 12 penetrates the bottom plate 19 and is fixedly connected to the fixed plate 18, and the fixed rod 12 is movably connected to the bottom plate 19, and a plurality of discharge ports 21 are provided at the outer periphery of the fixed tube 6 to discharge feed from The feed is poured into the top of the fixed tube 6, and can be discharged through the discharge port 21 and fall on the top of the bottom plate 19. The fixed ring 11 can block the feed on the top of the bottom plate 19 and accumulate it on the inner side of the fixed ring 11. The setting of the fixed rod 12 allows the fixed ring 11 to move synchronously with the mounting ring 15, so that it is convenient to drive the fixed ring 11 to descend when the umbrella body 1 is folded, until the bottom plate 19 loses the enclosure of the fixed ring 11, and the feed remaining on the bottom plate 19 can automatically fall off.

[0051] The implementation principle of this embodiment is as follows: when in use, the umbrella body 1 is first opened. When opening the umbrella body 1, one end of the positioning column 9 is first pulled out to the outside of the positioning hole 10, and then the adjustment cover 3 is moved up along the length direction of the fixing tube 6 until the positioning column 9 is stuck in a positioning hole 10 on the top, thereby locking the adjustment cover 3. At this time, the umbrella body 1 is fully opened, and then the umbrella body 1 is placed on the ground, and the inner side of the umbrella body 1 is the activity space of the chicks;

[0052] When the adjusting cover 3 moves upward, the mounting ring 15 will be driven to move upward synchronously, and the mounting ring 15 will then drive the fixing ring 11 to move upward synchronously, until the umbrella body 1 is fully opened, the fixing ring 11 is also sleeved on the outer periphery of the bottom plate 19, and the fixing plate 18 is also in contact with the bottom surface of the bottom plate 19 at this time, and then the feed can be poured from the receiving hopper 5, and then the feed will fall through the fixing pipe 6, and then be discharged from the discharge port 21 at the bottom of the fixing pipe 6, and finally the feed enters the feeding assembly for the chicks to eat;

[0053] When the umbrella body 1 needs to be folded, one end of the positioning column 9 can be pulled out to the outside of the positioning hole 10, and then the adjusting cover 3 is pressed down. During the pressing process of the adjusting cover 3, the mounting ring 15 will also move downward, thereby driving the umbrella ribs 2 to gradually fold, and the umbrella body 1 will also fold accordingly. When the mounting ring 15 moves downward, it will also drive the fixing ring 11 to move downward. When the positioning column 9 is again inserted into the inner part of the positioning hole 10 below, the umbrella body 1 is folded, and the fixing ring 11 also moves to the bottom of the bottom plate 19. The feed remaining on the top surface of the bottom plate 19 will automatically slide down from the top surface of the bottom plate 19 under the action of gravity, thereby achieving the purpose of facilitating the cleaning of the residual feed.

[0054] Embodiment 2:

[0055] Combination Figure 1 - Figure 7, based on Example 1, the present embodiment is further improved in that: the elastic member includes a feed pipe 7 fixed at the bottom of the receiving hopper 5 and a first spring movably sleeved on the outer periphery of the feed pipe 7, the feed pipe 7 is coaxially arranged with the receiving hopper 5, and the bottom of the feed pipe 7 is movably sleeved on the inner side of the fixed pipe 6, the top of the first spring is fixedly connected to the bottom surface of the receiving hopper 5, the bottom of the first spring is fixedly connected to the top surface of the fixed pipe 6, the feed pipe 7 is arranged, a baffle ring 22 coaxially arranged therewith is provided on the inner side of the fixed pipe 6, the outer ring of the baffle ring 22 is fitted with the inner ring of the fixed pipe 6, a plurality of adjusting rods 20 are fixed on the top of the baffle ring 22, and the top of the adjusting rod 20 is fixedly connected to the bottom of the feed pipe 7, the arrangement of the elastic member and the baffle ring 22 can block the discharge port 21 to prevent the feed in the fixed pipe 6 from being discharged from the discharge port 21 at will.

[0056] The implementation principle of this embodiment is as follows: in the absence of external force, the bottom of the material retaining ring 22 is always in contact with the bottom of the fixed tube 6, thereby sealing the discharge port 21, and the feed in the fixed tube 6 will not enter the material holding component. When it is necessary to add feed to the material holding component, the hopper 5 can be lifted upward, and the material retaining ring 22 moves upward synchronously with the hopper 5, thereby opening the discharge port 21, and the feed in the fixed tube 6 can be discharged from the discharge port 21 and enter the material holding component.

[0057] Embodiment 3:

[0058] Combination Figure 4 - Figure 5 On the basis of Embodiment 1 and Embodiment 2, this embodiment is further improved in that: a cleaning mechanism is installed on the fixed pipe 6, and the cleaning mechanism includes an annular pipe 23 sleeved on the outer periphery of the fixed pipe 6 and a gas distribution component installed on the outer periphery of the fixed pipe 6 and used for supplying gas into the annular pipe 23. The inner ring of the annular pipe 23 is fixed to the outer periphery of the fixed pipe 6 by a fixed shaft. The bottom surface of the annular pipe 23 is provided with a plurality of air outlets. The gas in the annular pipe 23 is discharged from the air outlets and blown onto the top surface of the bottom plate 19, so that the feed remaining on the top surface of the bottom plate 19 can be blown away, thereby achieving the purpose of cleaning the residual feed.

[0059] The number of gas distribution components is 2 to 3, and the gas distribution components include an air cylinder 25 fixed to the outer periphery of the fixed tube 6, a piston plate arranged in the air cylinder 25 and a piston rod 26 fixed to the top of the piston plate. The other end of the piston rod 26 is fixedly connected to the bottom surface of the mounting ring 15. A connecting pipe 24 is installed at the bottom of the air cylinder 25. The other end of the connecting pipe 24 is connected to the ring tube 23. The upward and downward movement of the mounting ring 15 will drive the piston rod 26 to move synchronously, so that when the mounting ring 15 descends to drive the umbrella body 1 to fold, the piston rod 26 can be driven to move downward to press the air in the air cylinder 25 into the ring tube 23.

[0060] The bottom surface of the annular tube 23 is flush with the top surface of the discharge port 21 , and the fixing rod 12 is located inside the annular tube 23 to prevent the annular tube 23 from blocking the feed from being discharged from the discharge port 21 .

[0061] The working principle of this embodiment is as follows: when the mounting ring 15 moves downward to drive the umbrella body 1 to fold, the mounting ring 15 will drive the piston rod 26 to move downward synchronously, thereby pressing the air in the air cylinder 25 into the ring tube 23, and the air in the ring tube 23 is then discharged from the air outlet and blown onto the top surface of the bottom plate 19, thereby blowing away the feed remaining on the top surface of the bottom plate 19.

[0062] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
