Description

Technical Field

[0001] The invention belongs to the technical field of poultry breeding equipment, and in particular relates to a chain-type precise quantitative feeding equipment for caged breeder chickens. Background Art

[0002] Breeder chickens have higher requirements than ordinary commercial laying hens. The amount of feed put into each trough is the same to ensure that each chicken eats the same amount of food every day. This will make the flock more uniform, the eggs produced are the same size, and the hatched chicks have consistent indicators. In the prior art, breeder chickens feed freely. Due to the different feed intakes among breeder chickens, the sizes of the eggs are different. Breeder chickens with high food intake lay large eggs, while breeder chickens with low food intake lay small eggs, resulting in inconsistent egg specifications and the inability to implement standardized production. For the chain feeding equipment used by conventional commercial laying hens, on the one hand, it is impossible to ensure the amount of feed required by all breeder chickens. On the other hand, it is difficult to control the precise quantitative feeding process because of the feed lines in the trough, which makes it impossible to eat cleanly.

[0003] Therefore, the prior art needs to be further developed and improved. Summary of the invention

[0004] In view of the various deficiencies of the prior art and in order to solve the above problems, a chain-type precise quantitative feeding device for caged breeder chickens is now proposed. The present invention provides the following technical solutions:

[0006] Furthermore, the material blocking device includes a material blocking tube arranged on the trough, a lifting device connected to the material blocking tube for driving the material blocking tube to rise and fall, and a guide support member for guiding the material blocking tube to a falling position in the trough, the guide support member is fixed on the inner wall of the trough, the material blocking tube is connected to the lifting device through a steel wire rope, and the lifting device pulls the steel wire rope back and forth so that the steel wire rope drives the material blocking tube to rise and fall to achieve material blocking of the material blocking tube to the trough.

[0007] Furthermore, the lifting device includes a rotating motor, a reel fixed to the end of the output shaft of the rotating motor, a pulley for changing the direction of the wire rope, and a lifting eye screw for limiting the lifting of the material blocking tube. There are multiple lifting eye screws, and each material blocking tube is lifted and lowered as a whole by passing multiple wire ropes through corresponding lifting eye screws.

[0008] Furthermore, the material blocking tube is set with different diameters based on the gender of the breeder chickens.

[0009] Furthermore, the chain feeding mechanism includes a trough material line for conveying feed, a sprocket for driving the trough material line to operate, and a material line drive for driving the sprocket to rotate.

[0011] Furthermore, an anti-overflow mechanism is provided at the lower opening of the storage trough, and the anti-overflow mechanism is arranged at the feeding end of the chain feeding mechanism.

[0012] Furthermore, the feeding mechanism includes a main material line for connecting the material tower and the material box, a weighing device arranged on the main material line, and an electric blanking valve arranged at the discharge end of the main material line. There are multiple electric blanking valves, and each electric blanking valve corresponds to a different material receiving port.

[0013] Furthermore, the weighing device includes a frame, on which are fixed a weighing mechanism for receiving and quantitatively weighing feed, a conveying adapter for conveying feed to the feed line, and a transition bin connecting the weighing mechanism and the conveying adapter.

[0014] Furthermore, the weighing mechanism includes a weighing bin for temporarily storing feed, a weighing assembly for sensing weight, a switch assembly for opening and closing the bottom of the weighing bin, and a connecting rod assembly for controlling the opening and closing of the switch assembly.

DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0040] like Figure 1-17 As shown, a chain-type precise quantitative feeding device for caged breeder chickens includes a chain feeding mechanism for automatic feeding arranged in a trough 800, a feed box 300 corresponding to each layer of the cage trough 800, a feeding mechanism for quantitative feeding of the feed box 300, and a feed tower 700 for storing feed, each feed box 300 is provided with a separate receiving port on the top, the feed tower 700 quantitatively delivers feed to different receiving ports through the feeding mechanism, the feed box 300 quantitatively releases feed into the trough 800 through the chain feeding mechanism, and a blocking device for controlling the feeding time is provided above the trough 800. By separately providing a receiving port for each feed box 300, the feed in the feed tower 700 is quantitatively delivered to each feed box 300 through the feeding mechanism, and each time the feed is fed, only one feed box 300 corresponding to the feeding port is quantitatively fed, and then the precise quantitative feeding of the chickens is achieved through the uniform feeding of the chain feeding mechanism and the control of the feeding time of the blocking device.

[0041] Furthermore, the material blocking device includes a material blocking tube 201 arranged on the food trough 800, a lifting device connected to the material blocking tube 201 for driving the material blocking tube 201 to rise and fall, and a guide support 207 for guiding the material blocking tube 201 to a falling position in the food trough 800. The guide support 207 is fixed on the inner wall of the food trough 800. The material blocking tube 201 is connected to the lifting device through a steel wire rope 202. The lifting device pulls the steel wire rope 202 forward and backward so that the steel wire rope 202 drives the material blocking tube 201 to rise and fall to achieve the blocking of the material blocking tube 201 to the food trough 800. The guide support 207 is a sheet structure, which is fixed to the inner wall of the trough 800 by a lifting screw 206, and is used to guide the falling position of the material blocking tube 201. The bottom protrusion of the guide support 207 is folded to form a triangular structure, which is used to limit the falling height of the material blocking tube 201 to prevent the steel wire rope suspended on the material blocking tube 201 from falling too low and contacting the material line, causing a malfunction.

[0042] Furthermore, the lifting device includes a rotating motor 203, a reel 204 fixed to the end of the output shaft of the rotating motor 203, a pulley 205 for changing the direction of the steel wire rope 202, and a lifting eye screw 206 for limiting the lifting of the material blocking tube 201. The lifting eye screw 206 is provided in plurality, and each material blocking tube 201 is lifted and lowered as a whole by passing through the corresponding lifting eye screw 206 through a plurality of steel wire ropes 202. Since the process of pulling the material blocking tube 201 requires continuous friction of the steel wire rope 202, the steel wire rope 202 connected at the lifting eye screw 206 is usually provided with a thick steel wire with a larger diameter, while other places only need to be provided with a thin steel wire due to less friction, thereby reducing equipment cost and maintenance cost on the basis of ensuring normal operation. A lifting screw 206 is provided at each group (generally 1.6m) position as a fixing point for lifting the material blocking tube 201. A 5mm steel wire is passed through the lifting screw 206. The front end of the steel wire is connected to a 2mm steel wire rope 202. The steel wire rope 202 is connected to the reel 204 through a pulley 205. The motor of the reel 204 rotates to pull the 5mm steel wire back and forth. The material blocking tube 201 is fixed on the 5mm steel wire through the thin steel wire rope 202. As the 5mm steel wire moves back and forth, the material blocking tube 201 is driven to move up and down.

[0043] Further, the material blocking tube 201 is set with different diameters based on the gender of the breeder chickens. The hens use a material blocking tube 201 with a diameter of 50 mm. The roosters have large heads and therefore require a larger feeding trough 800 for feeding, so the material blocking tube 201 does not need to be set very large. Preferably, the roosters use a material blocking tube 201 with a diameter of 40 mm.

[0044] Furthermore, the chain feeding mechanism includes a trough material line 101 for conveying feed, a sprocket 102 for driving the trough material line 101 to operate, and a material line drive 103 for driving the sprocket 102 to rotate. The material line drive 103 is located on the front trough, opposite to the feed box, and is driven by a reduction motor to drive the sprocket to drive the entire material line to circulate. The sprocket 102 rotates through the material line drive 103, thereby driving the trough material line 101 under the sprocket 102 and the gear-connected trough material line 101 to transmit, so that the feed contained in the trough material line 101 moves synchronously with the trough material line 101, completing the feeding process from the feed box 300 to the trough 800.

[0045] Furthermore, the feed box 300 includes a storage trough 301 for temporarily storing feed, the storage trough 301 is opened at the top and bottom, and a material thickness adjustment device 302 for limiting the discharge amount is provided at the lower opening of the storage trough 301, and the material thickness adjustment device 302 is provided at the discharge end of the chain feeding mechanism. The material thickness adjustment device 302 includes a material thickness adjustment plate and a lifting assembly for lifting the material thickness adjustment plate, and there is a scale on the adjustment plate, which can adjust the discharge thickness to ensure that the feed in the feed box 300 can evenly cover the entire trough 800, thereby ensuring that the chickens at different positions in the cage can obtain the same amount of feed.

[0046] Furthermore, an anti-overflow mechanism 303 is provided at the lower opening of the storage trough 301, and the anti-overflow mechanism 303 is provided at the feeding end of the chain feeding mechanism. The feeding end of the chain feeding mechanism is provided with an anti-overflow mechanism 303. If the feed brought by the trough material line 101 after one turn is too thick, it will overflow at the entrance of the feed box. The anti-overflow mechanism 303 is an anti-overflow sprocket driven by the trough material line 101, which has teeth and runs with the trough material line 101. It can quickly introduce excess feed into the feed box 300 to prevent the over-thick feed brought by the trough material line 101 from overflowing here, resulting in waste of feed and pollution of the environment. A plurality of observation windows 304 are provided on the outside of the feed box 300 near the chain feeding mechanism to facilitate observation of the amount of feed in the storage trough 301 and whether there is accumulation or blockage. The detachable design makes it easy to clean once foreign matter or blockage enters the feed box.

[0047] Furthermore, the feeding mechanism includes a main material line 600 for connecting the material tower 700 and the material box 300, a weighing device 400 arranged on the main material line 600, and an electric blanking valve 500 arranged at the discharge end of the main material line 600. The main material line 600 is provided with at least one of a spring auger feeding, a screw feeding, and a plug feeding for driving feed transmission. There are multiple electric blanking valves 500, and each electric blanking valve 500 corresponds to a different material receiving port. The main material line 600 is divided into a front section material line and a rear section material line, which are connected by a weighing device 400. The feed in the material tower 700 is first transported to the weighing device 400 through the front section material line. The weighing device 400 weighs and quantitatively releases the feed of a predetermined weight to the rear section material line. The electric blanking valves 500 arranged on the rear section material line are opened one by one in sequence according to the instructions of the controller. Each time the weighed feed is opened, an electric blanking valve 500 is opened corresponding to the weighed feed. The rear section material line completely puts the weighed feed into the corresponding receiving port through the opened electric blanking valve 500, thereby realizing quantitative feeding of each material box 300. There is a separate corresponding electric blanking valve 500 at the main material line 600 above the feeding port of each material box 300. A set of control programs is used to control the opening and closing sequence of the electric switch, and ensure that the weighed material is completely put into the designated material box 300. The amount of feed in each feed box 300 is determined according to the number of chickens raised on this floor, and each feeding must empty the feed box 300. The running time of all feed lines and the lifting time of the material blocking pipe 201 are controlled by a set of control programs, and can be automatically operated at a fixed time.

[0048] Furthermore, the weighing device 400 includes a frame 416, on which a weighing mechanism for receiving and quantitatively weighing feed, a conveying adapter 418 for conveying feed to the feed line, and a transition bin 419 connecting the weighing mechanism and the conveying adapter 418 are fixed. The feed falls into the weighing mechanism from above the weighing mechanism and is buffered in the weighing mechanism until it reaches a predetermined standard weight, and then the weighing mechanism releases the feed to the transition bin 419, which is funnel-shaped and collects the feed into the conveying adapter 418, and then conveys it to the rear section of the feed line that requires quantitative feeding, and the transition bin 419 also serves as a buffer for the feed.

[0049] Further, the weighing mechanism includes a weighing bin 401 for temporarily storing feed, a weighing assembly for sensing weight, a switch assembly for realizing the opening and closing of the bottom of the weighing bin 401, and a connecting rod assembly for controlling the opening and closing of the switch assembly, wherein the switch assembly is fixed to the bottom of the weighing bin 401, and the connecting rod assembly is fixed to the side of the switch assembly. The weighing bin 401 is transparently arranged from top to bottom, and a switch assembly and a connecting rod assembly are arranged at the bottom of the weighing bin 401. The switch assembly is controlled by the connecting rod assembly, which is convenient for controlling the accumulation and release of feed in the weighing bin 401, and the switch assembly can instantly complete the opening and closing action. The whole process is realized by mechanical structure automation, avoiding the complex coordination of multiple components and energy waste when the traditional motor controls the switch. Further, the weighing assembly includes a support beam 420 fixed on the frame 416, a weighing sensor 421 fixed on the support beam 420, and a weighing fixed plate 422 fixed on the outer wall of the weighing bin 401, and the weighing bin 401 is fixed to the weighing sensor 421 through the weighing fixed plate 422. The support beam 420 is used to support the weighing bin 401 and the switch assembly and the connecting rod assembly connected to the weighing bin 401. The support beam 420 is arranged on the front and rear sides of the weighing bin 401. The weighing sensors 421 are arranged on the front and rear sides of the weighing bin 401 respectively. The weighing fixed plate 422 corresponding to the position of the weighing sensor 421 extends outward to form weighing ears. The weighing ears on both sides are fixed on the weighing sensors 421. When the feed falls into the weighing bin 401, the feed can be accumulated in the weighing bin 401 due to the obstruction of the bottom switch assembly, and is monitored by the weighing sensors 421 fixed on the support beam 420 on both sides of the weighing bin 401. The weighing sensors 421 on both sides are balanced, thereby ensuring the accuracy of weighing. Further, a box 417 is fixed on the frame 416, and the support beam 420 is fixed on the box 417. The box 417 encloses the weighing mechanism as a whole to prevent feed dust from affecting precision components such as the weighing sensor 421 and the electromagnetic push rod 411. An inspection window is provided on the box 417 corresponding to the position of the connecting rod assembly, and an inspection cover 423 is detachably connected to the inspection window through fasteners. Since the connecting rod assembly is a movable assembly, abnormal conditions are inevitable during long-term operation. The inspection window can be conveniently and quickly checked or repaired without disassembling the box 417. The frame 416 also includes a transition bin 419 support frame for supporting the transition bin 419, and the bottom of the transition bin 419 is fixed to the transition bin 419 support frame. Furthermore, the bottom of the weighing bin 401 is fixedly connected to the weighing bin flange 402 through the first fastener 407, and the switch assembly is hinged on the weighing bin flange 402.A hollow connecting ring is provided in the center of the weighing bin flange 402. The size of the connecting ring is designed to match the outer diameter of the bottom of the weighing bin 401. There are multiple mounting holes in a circular array on the connecting ring. Bolt fasteners pass through the mounting holes to fix the connecting ring to the wall of the weighing bin 401. A horizontal fixing plate is fixedly welded at the bottom of the connecting ring. The front and rear sides of the fixing plate are provided with convex edges that bend downward and extend, which are used to fix and connect the switch assembly and the connecting rod assembly. Further, the switch assembly is symmetrically arranged on the left and right, including two switch plates 403 formed by left and right splicing. The two ends of the two switch plates 403 are respectively fixedly connected to two supporting vertical plates 404, and the supporting vertical plates 404 are hinged to the side of the weighing bin flange 402 through the first hinge 405. The two supporting vertical plates 404 are relatively arranged on the front and rear sides of the fixing plate, and are hinged to the convex edges on both sides of the fixing plate through the first hinge 405. The supporting vertical plates 404 are arranged in a triangular structure, and the two opposing supporting vertical plates 404 form a triangular clearance space in the middle. Furthermore, a counterweight rod 406 is provided on the outer side of the switch plate 403, and the counterweight rod 406 is fixed to the support vertical plate 404 by a second fastener 415. The counterweight rod 406 is located on the left and right sides of the fixed plate, and is respectively fixed to the support vertical plates 404 on both sides by the second fastener 415. Preferably, the fixed position of the counterweight rod 406 is lower than the vertical height of the first hinge 405, and the distance from the counterweight rod 406 to the first hinge 405 is smaller than the distance from the first hinge 405 to the opening and closing part of the switch plate 403, so that under the normal gravity, no external force is required, and the switch plates 403 on both sides can be automatically closed by relying only on the counterweight rods 406 on both sides. Further, the connecting rod assembly includes a first connecting rod 408 and a second connecting rod 409 which are hinged to each other at one end, the first connecting rod 408 and the second connecting rod 409 are hinged through a second hinge 410, and the other ends of the first connecting rod 408 and the second connecting rod 409 are respectively hinged to the supporting upright plates 404 on both sides through a third hinge 414. When the switch plate 403 is closed, the first connecting rod 408 and the second connecting rod 409 are both in a horizontal position, just realizing the hinge connection of the left and right supporting upright plates 404, and the first connecting rod 408 and the second connecting rod 409 are provided with a second hinge 410 in the middle position, which is convenient for destroying the balance of the supporting upright plates 404 on both sides by external force, thereby realizing the opening state of the switch plate 403. Further, an electromagnetic push rod 411 for pushing the second hinge 410 to move upward is provided directly below the second hinge 410, and the electromagnetic push rod 411 is fixed to the side of the weighing bin flange 402. The electromagnetic push rod 411 is arranged directly below the first link 408 and the second link 409, preferably directly below the second hinge 410, so that only a small thrust is needed to destroy the balance between the first link 408 and the second link 409, so that the first link 408 and the second link 409 rotate relative to each other, thereby realizing the open state of the switch plate 403.The electromagnetic push rod 411 is controlled by a signal, and the push rod only needs to apply a small force to break the balance between the first connecting rod 408 and the second connecting rod 409. At this time, the switch plate 403 continues to open under the gravity of the feed without applying additional external force. When the feed is released, the switch plate 403 automatically returns to its original position under the gravity of the counterweight rods 406 on both sides. Therefore, this structure can achieve the effect of automatic control of the switch plate 403 and saving energy loss. Further, a guide seat 412 is fixed between the weighing bin flange 402 and the weighing bin 401, and a guide hole 413 is provided on the guide seat 412, and the first connecting rod 408 or the second connecting rod 409 passes through the guide hole 413. The guide seat 412 is set as an L-shaped long strip plate, and the guide hole 413 is a long strip hole set on one side of the plate surface, and the other side of the plate surface is used to support and fix the guide seat 412. The guide hole 413 also plays a limiting role, preventing the switch plate 403 from over-flipping and malfunctioning due to excessive hinged movement of the first connecting rod 408 or the second connecting rod 409. Furthermore, the guide seat 412 is vertically fixed between the weighing bin flange 402 and the weighing bin 401, and a semicircular buffer pad for buffering the connecting rod is fixed on the guide seat 412, and the semicircular buffer pad is fixed below the guide hole 413. The guide seat 412 is fixed vertically, so that the first connecting rod 408 or the second connecting rod 409 passing through the guide hole 413 on the guide seat 412 moves up and down in the vertical direction, avoiding deviation and leakage due to loose hinges. Furthermore, a rubber strip for buffering sealing is fixed on the switch plate 403. The rubber strip is fixed on the front and rear sides of the switch plate 403 to buffer the impact force between the switch plate 403 and other components when it is closed. Furthermore, a bending plate extending downward is provided at the left and right joints of the two switch plates 403. The bending plate can ensure the sealing degree of the left and right joints of the two switch plates 403, and play a role of abutting each other when the two switch plates 403 are closed, thereby avoiding leakage.
