Description

Technical Field

[0001] The present invention belongs to the technical field of poultry farming, and particularly relates to a free-range chicken pen for captive breeding. Background Art

[0002] Chicken meat and eggs are basic foods that people cannot do without in their daily lives. In order to meet market demand and improve egg production rate and meat texture, people have started to change the breeding method of cage breeding, such as free-range chickens, vigorous chickens, etc. emerging in an endless stream. Although the meat texture of chicken has been improved, the growth cycle has been prolonged, the breeding cost has increased, the market supply has decreased, and the price of chicken has increased, so that it has become a gift chicken and cannot be popular among the general public. Correspondingly, the egg production rate of the corresponding eggs has also decreased significantly, resulting in a relatively high price for such eggs and also being unable to be popular among the general public. At the same time, there are also relatively high losses of chickens (mainly lost, killed by natural enemies, and died of disease) and egg losses (scattered egg production, inconvenient collection, untimely collection, resulting in accidental breakage, omission during the harvesting process, and being carried away by natural enemies) during the free-range process, resulting in a small scale and small number of such breeding models.

[0003] Therefore, people have developed a semi-free-range model, that is, free-range in a chicken breeding shed provided by a patented invention with an authorization announcement number of CN104126523B. It can provide a relatively safe breeding environment, is easy to manage, can accurately control the feeding of feed, and can collect eggs more centrally through the egg-laying boxes arranged therein, greatly reducing the losses of chickens and eggs and facilitating the increase in chicken meat and egg production. However, the chicken racks (multi-layer triangular steel frames), chicken coops (for egg production), and activity areas (an open ground) arranged therein are all relatively traditional, with inconvenient (laying straw on the bottom surface of the activity area and cleaning it once every 2 to 3 days, with a large workload) and incomplete (adopting cleaning and scraping methods) feces cleaning, easy accumulation of more ammonia, semi-artificial feed feeding, and the need to enter the shed for egg harvesting. There are frequent entries and exits of staff into the breeding shed, increasing the difficulty of epidemic prevention and the chance of the chicken flock getting sick. Summary of the Invention

[0004] The purpose of the present invention is to provide a free-range chicken breeding shed with easy and thorough feces cleaning, avoiding frequent entry and exit of personnel into the breeding shed, simple environmental disinfection and sterilization, and no need for artificial feed feeding.

[0005] To achieve the above object, the present invention provides a free-range chicken pen for captive breeding, including a shed body. The special feature is that it further includes a chicken rack assembly arranged on one side inside the shed body and extending along the length direction of the shed body for the chicken flock to rest;

[0006] An activity field located between the two sides in the length direction of the shed body for the chicken flock to move and eat;

[0007] A cleaning system arranged in the activity field for cleaning the excrement of the chicken flock and sterilizing and preventing epidemics;

[0008] An isolation device disposed between the activity field and the chicken rack assembly for blocking the chicken flock outside the activity field and temporarily enclosing them in the area where the chicken rack assembly is located;

[0009] A feeding device disposed between the isolation device and the chicken rack assembly for the chicken flock to eat and drink;

[0010] An egg-laying rack assembly disposed outside the chicken rack assembly and on one side wall of the shed body for the chicken flock to lay eggs and facilitate the collection of eggs from the outside of the shed body.

[0011] The beneficial effects of the present invention are: It has a good division of functional units, is clean in a timely, simple, comprehensive and thorough manner, greatly reduces the entry and exit of personnel, significantly improves the epidemic prevention and disease control effects, reduces the chicken loss rate and the loss rate of eggs, improves economic benefits, and is conducive to the appropriate and stable reduction of the selling prices of chicken and eggs, and has good inclusive value.

[0032] Figure 20 is Figure 19 The enlarged view of part A in Detailed implementation manners

[0033] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined purpose, the following details the specific implementation manners, structural features and their effects of the present invention in conjunction with the drawings and embodiments.

[0034] This embodiment provides a Figure 1 free-range chicken pen shown in the figure, including a pen body 1, and a chicken rack assembly 2 provided on one side inside the pen body 1 (such as Figure 1 the right side shown in the figure) and extending along the length direction of the pen body 1 for the chicken flock to rest;

[0035] It also includes an activity field 3 (i.e., Figure 1 the central area shown in the figure) between the two sides in the length direction of the pen body 1 for the chicken flock to move and eat; it also includes a cleaning system provided in the activity field 3 for cleaning the excrement of the chicken flock and sterilizing and preventing epidemics;

[0036] It further includes a separation device 4 disposed between the activity field 3 and the chicken rack assembly 2, which is used to block the chicken flock outside the activity field 3 and temporarily enclose it in the area where the chicken rack assembly 2 is located;

[0037] It further includes a feeding device 5 disposed between the separation device 4 and the chicken rack assembly 2 for the chicken flock to eat and drink;

[0038] It further includes an egg-laying rack assembly 6 disposed outside the chicken rack assembly 2 and at one side wall of the shed body 1, which is used for the chicken flock to lay eggs and facilitates harvesting eggs from the outside of the shed body 1.

[0039] Combined with the attached drawings of the specification Figure 1 It can be seen that for the free-range chicken pen provided in this embodiment, the activity field 3 located in the middle (or it can be biased to the other side, which can be flexibly designed according to the actual situation on site for the convenience of management) in the shed body meets the free-range of the chicken flock, enhances the activity ability of the chicken flock, is suitable for raising free-range chickens (that is, free-range, the chicken flock has a large activity space and can run, jump, chase, etc.), improves the texture of the chicken meat, and effectively physically separates the activity field 3 and the chicken rack assembly 2 through the separation device 4 to avoid cross-contamination between the two (mainly, it can be cleaned at different times. For example, when the chicken flock is in the activity field, the area outside the separation device can be cleaned, and vice versa, the activity field can be cleaned in time to avoid excessive accumulation of feces and sundries, which is beneficial to disease prevention and control). The egg-laying rack assembly 6 disposed at one side wall in the shed body 1 meets the requirements of the egg-laying place and can harvest eggs outside the shed body 1, avoiding the trouble and risks of epidemic prevention and disease control brought by personnel entering the shed body 1 to harvest eggs. At the same time, with the isolation of the shed body 1, the loss of eggs (such as being stolen by weasels and crows) can be effectively avoided, ensuring the safety of egg production; the cleaning system in the activity field 3 can realize the timely removal of fecal sewage, eliminating the trouble of laying straw, rice husks and other linings in the existing method to clean fecal sewage every two or three days and the inevitable accumulation of ammonia.

[0040] This embodiment mainly takes the specific composition of the activity field 3 as an example in combination with the attached drawings Figure 2 In the attached drawings Figure 2 the activity field 3 includes a rectangular enclosure edge 7, a foundation pit 8 whose top edge is surrounded by the rectangular enclosure edge 7, a plurality of vertical sliding grooves 9 fixed on the circumferential side walls of the foundation pit 8, a supporting grid 11 that can be lifted along the vertical sliding grooves 9 through a plurality of sliders 10 corresponding to the plurality of vertical sliding grooves 9 one by one on the periphery, and a plurality of winches 12 fixed on the ground outside the rectangular enclosure edge 7, which are respectively located on both sides of the length direction of the foundation pit 8 and are axially symmetrically distributed about the length direction of the foundation pit 8; among them, the supporting grid 11 includes Figure 3The multiple support cross beams 13 and support longitudinal beams 14 shown are respectively arranged corresponding to two vertical sliding grooves 9 which are oppositely arranged horizontally and longitudinally along the foundation pit 8; and sliders 10 are respectively fixed at the two end portions of the support cross beam 13 and the support longitudinal beam 14 for being placed into the corresponding vertical sliding groove 9; and connecting lifting lugs 15 (ordinary lifting rings or hooks can be adopted, and no special design is required) are fixed at both ends of the support cross beam 13 and the support longitudinal beam 14 for being fixedly connected with the steel cables of a corresponding winch 12. Then, under the pulling action of the winch 12, the lifting of the supporting grid 11 is realized. When the winch 12 reverses, it will lower itself under the action of gravity and can be stopped at the position where the chickens move according to needs, or can also be stopped in the water tank 18 in the foundation pit 8 to soak and wash feces and sundries by means of the water in the water tank 18.

[0041] A plurality of fixed pulley brackets 16 are fixed on the ground outside the rectangular enclosure 7. The steel cable is supported by the fixed pulley 17 at the top thereof to form the hoisting stroke height of the winch 12. This is the usual practice of using a winch on flat ground, which can provide sufficient height difference for the lifting operation of the winch to realize the lifting and lowering of the hoisted object such as the supporting grid 11. It should be noted that the fixed pulley brackets 16 and the protective guiding fixed pulleys 17 at their tops are axially symmetrically distributed about the length direction of the foundation pit 8. Similarly, winches, pulley brackets, etc. of the same specifications can also be arranged at both ends of the foundation pit 8 in the length direction according to needs to realize the simultaneous hoisting of the four sides of the supporting grid 11. The start and stop of all winches adopt mature unified PLC programming control or are controlled by the same power controller. This is the prior art and not the inventive point of this embodiment, so it will not be elaborated here.

[0042] The supporting grid 11 provided in this embodiment is mainly used when the chickens move freely. The reason for designing it as a grid structure is to timely drop feces through the mesh holes of the grid into the foundation pit 8. And after the chickens finish moving freely, the supporting grid 11 can be conveniently washed to avoid the accumulation of feces and provide a clean activity place for the chickens. Of course, the design of the mesh holes should be less than 1 cm and greater than 0.5 cm, which can not only prevent the chicken feet from getting stuck in them, but also facilitate most chicken feces to fall into the foundation pit through the mesh holes.

[0043] In order to facilitate and more thoroughly clean feces, fallen chicken feathers and other sundries, the cleaning system provided in this embodiment on the basis of the foregoing embodiment includes Figure 4The water tank 18, sedimentation tank 19, high-pressure water flushing assembly, scraping assembly, ozone sterilization assembly and air drying assembly shown in the figure; wherein, the water tank 18 is installed in the foundation pit 8 (the water tank is located below the bottom end of the vertical slide 9 or the lower end of the vertical slide 9 is located outside the water tank 18. In order to improve the flatness of the installation surface or reduce the gap, a concave vertical groove that can accommodate the lower end of the vertical slide 9 is provided on the vertical side wall of the water tank 18, so that the clamp and installation of the lower end of the vertical slide 9 can be realized. The space for loading and the slider 10 are given way. At this time, the slider 10 needs to be connected to the supporting crossbeam 13 or the supporting longitudinal beam 14 through the connecting steel plate at the top thereof, and the connecting steel plate is a U-shaped steel plate. The two opposite vertical side walls of the U-shaped steel plate are respectively fixedly connected to the slider 10, the supporting crossbeam 13 or the supporting longitudinal beam 14, so that the U-shaped steel plate can be used to straddle the side wall of the water tank 18, so that it can be ensured that after the slider 10 slides down into place, the supporting grid 11 is immersed in water) One along the length of the foundation pit 8 A plurality of drainage ports 20 are provided on the side wall in the degree direction, and a solenoid valve or a manual valve (that is, a commonly used pipeline solenoid valve, which is used to open or close the pipeline channel to achieve drainage or stop drainage) or a manual valve is installed on the external pipe section of the drainage port 20, and is connected to the sedimentation tank 19 excavated outside the shed body 1 through a drainage pipe. In this way, the cleaned feces, chicken feathers and other debris can be collected in the water tank 18 first, which can effectively prevent the ammonia generated by the feces from accumulating in the shed body 1. In the evening of each day, after the ground and the supporting grid in the shed body 1 are cleaned, the solenoid valve is opened to discharge the feces, chicken feathers and other debris in the water tank 18 into the sedimentation tank 19 outside the shed body 1. Afterwards, the traditional multi-stage water treatment technology is used to achieve graded treatment of sewage, complete the collection and utilization of feces, and the purified sewage can also be used for the collection of secondary feces, irrigation (such as the vegetable greenhouse around the chicken farm) and municipal sewage pipeline according to specific indicators.

[0044] In order to ensure cleanliness and avoid sediment retention, the bottom plate of the water tank 18 provided in this embodiment is inclined in the horizontal direction (i.e., the width direction of the shed body 1 or the width direction of the foundation pit 8), the drain port 20 is located at the lowest position of the bottom plate, and the outer edge of the drain port 20 is inclined downward and outward to facilitate rapid drainage and prevent feces from settling and accumulating at the drain port 20. In order to clean the supporting grid more thoroughly, quickly and comprehensively, multiple ultrasonic generators can be installed around the foundation pit 8, so that the ultrasonic release heads are embedded in the side walls of the water tank 18, and ultrasonic waves are used to clean the supporting grid 11 silent in the water tank 18.

[0045] High pressure water flushing kit includes Figure 5A plurality of longitudinal slide bar assemblies 21 fixed to the top of the shed body 1 and extending along the length direction of the shed body 1, a multi-nozzle high-pressure water spraying member 23 connected to the longitudinal slide bar assemblies 21 through a transverse connecting block 22, a high-pressure resistant water pipe 24, and a high-pressure water pump 25 (according to actual needs, the high-pressure water pump 25 is installed inside or outside the shed body 1, preferably installed inside the shed body 1 and at a position close to the edge to provide shelter and protection for the high-pressure water pump to avoid being exposed to wind and sun). The high-pressure water pump 25 is connected to the water supply interface of the multi-nozzle high-pressure water spraying member 23 through the high-pressure resistant water pipe 24. The high-pressure resistant water pipe 24 is erected on a plurality of longitudinal support rods 30 extending along the length direction of the shed body 1, so that the high-pressure resistant water pipe 24 is always suspended (i.e., not in contact with the ground and located at a certain height in the space) and supported (supported by the longitudinal support rods) during the reciprocating movement following the multi-nozzle high-pressure water spraying member 23.

[0046] The longitudinal slide bar assembly 21 includes Figure 5 The longitudinal support rod 26 as shown, a first driving motor 27 fixed to one end of the longitudinal support rod 26, a lead screw 28 fixed between the two ends of the bottom surface of the longitudinal support rod 26, and a moving slider 29 threadedly connected to the lead screw 28. The output shaft of the first driving motor 27 is connected to one end of the lead screw 28 through a first coupling. The moving slider 29 is fixedly connected to the top surface of the transverse connecting block 22. Through this structure, mobile water spraying and flushing of the activity field can be realized to complete cleaning.

[0047] Meanwhile, in order to achieve good cleaning, especially to clean the feces adhered to the supporting grid, the scraping assembly provided in this embodiment includes Figure 6 The scraping plate 31 as shown (a scraping blade 94 with a cross-section of an inverted triangle can be selected, which has a relatively heavy self-weight and has a good pressing effect), at least one reciprocating movement assembly, and a slide bar 32 (a stainless steel pipe can be selected). Among them, the reciprocating movement assembly includes a lead screw 33 arranged on one length direction side of the rectangular enclosure edge 7, a slider 34 threadedly connected to the lead screw 33, a lead screw support 35, and a second driving motor 36 fixed to one end of the lead screw support 35 and connected to the lead screw 33 through a second coupling. The slide bar 32 is fixed on the other length direction side of the rectangular enclosure edge 7. In this way, the lead screw 33, the lead screw support 34, and the slide bar 32 all extend along the length direction of the rectangular enclosure edge 7. One end of the scraping plate 31 is fixedly connected to the slider 34, so that it reciprocates along the lead screw 33 driven by the slider 34, and the other end of the scraping plate 31 is sleeved on the slide bar 32 through a sleeve to reciprocate along the slide bar 32. It should be noted that both ends of the slide bar 32 can be fixed to the other side of the rectangular enclosure edge 7 through slide bar supports 96 (such as cement piers or steel plate supports). In order to ensure that the scraping plate 31 reciprocates along the length direction of the supporting grid 11 and can always press on the top surface of the supporting grid 11 to scrape the feces or other sundries adhered to the top surface of the supporting grid 11, the scraping plate 31 provided in this embodiment includesFigure 6 The cross bar 93, the wiper blade 94 connected between the slider 34 and the slide bar 32, and a plurality of compression springs 95 fixedly arranged in parallel between the cross bar 93 and the wiper blade 94 as shown. With the elastic reset function of the compression springs 95, during the process of the wiper blade 94 scraping against the top surface of the supporting grid 11, the wiper blade 94 always presses against the top surface of the supporting grid 11 and has self - telescopic property, which can not only scrape the feces adhered to the top surface of the supporting grid 11, but also not damage the supporting grid 11. Finally, it should be noted that when installing the slide bar 32, the lead screw 33, the slider 34, the lead screw support 35 and the second driving motor 36 of the scraping assembly, it is required that the slide bar 32, the lead screw 33 and the slider 34 are all located inside the vertical chute 9 after installation, that is, set towards the inside of the foundation pit 8. In this way, it will not interfere with the steel cable for pulling the supporting grid 11 by the winch 12, ensuring that the two operate independently without interference. In this way, it is required that the lead screw support 35 and the slide bar support 96 of the slide bar 32 are embedded at both ends of the rectangular enclosure edge 7 in the length direction and are located inside the vertical chute 9. Finally, in order to reduce the pressure on the slide bar 32, in this embodiment, a support roller is arranged at one end of the cross bar 93 adjacent to the slide bar 32 (it can be simply welded with a steel pipe section on the cross bar 93 and the mounting seat of the roller), and the support roller bears the load, while the slide bar 32 mainly functions for limiting and guiding. Of course, multiple parallel scraping assemblies can also be arranged along the length direction of the foundation pit 8. This method is more suitable for foundation pits with a length exceeding 30 meters. Although it will increase the cost, the later operation is more reliable, and it can avoid the potential problem of poor support stability during long - distance movement. Especially, it can significantly reduce the length of the slide bar 32 (if the slide bar is too long, it will sag due to its own factors such as self - weight and material ductility, and the whole will form a downward - curved arc, which is not conducive to the requirement of linear operation), ensuring its supporting stiffness and facilitating the guarantee of operation stability.

[0048] The ozone sterilization component includes Figure 7 The ozone generator 36, the cold water storage tank 37 and the multi - branch pipes 38 as shown. Among them, the ozone generator 36 is fixed on the site outside the rectangular enclosure edge 7 and is connected to the cold water storage tank 37 through a pipe valve assembly (the cold water storage tank 37 can also be installed on the site outside the rectangular enclosure edge 7, or both the ozone generator 36 and the cold water storage tank 37 are installed in a separate room outside the shed body 1 or inside the shed). The cold water storage tank 37 is connected to the multi - branch pipes 38 through a plurality of pipe valves. The water outlets of the multi - branch pipes 38 are evenly distributed around the foundation pit 8 or on one side edge of the foundation pit 8 and are immersed in the pre - stored water surface in the water tank 18 at a depth range of at least 30 cm to 50 cm below the water surface, injecting ozone into the water for sterilization.

[0049] The air-drying component includes multiple heat-generating blowers evenly installed on the top of the rectangular enclosure edge 7 (which can be fixed to the top of the rectangular enclosure edge 7 through vertical poles, or placed on the top of the rectangular enclosure edge 7 through movable brackets or trolleys, etc., using common methods). The air outlet of each heat-generating blower is elliptical, with its major axis parallel to the length direction of the foundation pit 8 and all facing the supporting grid 11 to blow air.

[0050] To achieve a better hot air drying effect, the heat-generating blowers provided in this embodiment include Figure 8 the high-position long-range blower 39 and the low-position short-range blower 40 shown in the figure, which are respectively installed on the high-position mounting seat 41 and the low-position mounting seat 42. The high-position mounting seat 41 and the low-position mounting seat 42 are arranged on the same transverse vertical line of the foundation pit 8, and are respectively used to blow air to the part within more than half of the width range and the part within less than half of the width range of the supporting grid 11; the high-position mounting seat 41 is located outside the low-position mounting seat 42 and is 30 to 35 centimeters higher than the low-position mounting seat 42 (this is only an example here and is not particularly limited. The specific height difference also needs to be designed according to the specific dimensions of the activity field, foundation pit, and rectangular enclosure edge and determined after multiple tests), forming high-low and far-near air blowing. And the height difference here is mainly to ensure that an acute angle is formed between the air blowing and the top surface of the supporting grid 11, which can increase the air blowing area with the supporting grid 11 and improve the air blowing and drying effect.

[0051] The isolation device 4 includes Figure 9 multiple door frames 43 within the range of 1.5 to 2.5 meters from the long side (i.e., the side in the length direction) of the rectangular enclosure edge 7 and electric rolling shutters 44 installed in the door frames 43; the multiple door frames 43 are sequentially installed on the buried support plate 45 (which can be a precast concrete slab or a buried steel plate) along the length direction of the shed body 1; ultraviolet UV lamp strips 46 are installed on the door frames 43. Through this isolation device 4, the activity field 3 can be separately isolated, so that it can be ensured that the chicken flock moves freely in the activity field 3 during the free-range activity time. At the same time, cleaning operations can be carried out in other areas, or after isolating the chicken flock in an area outside the activity field 3, the activity field 3 can be cleaned without being disturbed by the activities of the chicken flock.

[0052] The feeding device 5 includes Figure 10 multiple feed bins 47, a feed conveying pipeline 48, a feed loader 49, and a feed storage bin 50 shown in the figure; among them, the feed storage bin 50 and the feed loader 49 are placed at one end in the length direction outside the shed body 1, which is convenient for storing and loading feed outside the shed body 1 and avoiding affecting the environment inside the shed body 1.

[0053] The first discharge pipe section at the bottom of the feed storage bin 50 extends to the inside of the first feed inlet of the feed loader 49, and the second discharge pipe section of the feed loader 49 extends to the inside of the second feed inlet of the feed conveying pipeline 48 to convey the feed onto the feed conveyor belt assembly 51 installed in the feed conveying pipeline 48; the feed conveying pipeline 48 is erected on the top of the support 57, and the support rollers 55, the driving roller 58, and the third driving motor 59 of the feed conveyor belt assembly 51 are all installed on the bottom surface of the feed conveying pipeline 48, and the driving roller 58 and the third driving motor 59 are both located at the feed inlet end of the feed conveying pipeline 48.

[0054] A plurality of Figure 10 、 Figure 11 The third discharge pipe sections 52 distributed along the length direction as shown in the figure are connected to the side wall of the feed conveying pipeline 48. The lower part of the inner end of the third discharge pipe section 52 is in a tongue shape and extends to the lower part of one side of the feed conveyor belt assembly 51; a plurality of arc-shaped guide strips 54 are arranged on the object supporting surface 53 of the object supporting the transmission belt of the feed conveyor belt assembly 51, and the height of the arc-shaped guide strip 54 gradually decreases from the other side far away from the third discharge pipe section 52 to the side adjacent to the third discharge pipe section 52, forming a tendency to squeeze the feed towards the side of the third discharge pipe section 52. The support rollers 55 of the feed conveyor belt assembly 51 are distributed between adjacent third discharge pipe sections 52 (see Figure 10 ), so that the transmission belt of the feed conveyor belt assembly 51 passing through the third discharge pipe section 52 sags under the action of its own weight and the heavy pressure of the feed, so that the feed falls into the third discharge pipe section 52; an electric cover plate 56 is installed at the outlet of the third discharge pipe section 52, and the electric cover plate 56 is driven by a servo motor 97 shown in Figure 12 outside the third discharge pipe section 52 to rotate the electric cover plate 56 and the rotating shaft 98 at the outlet of the third discharge pipe section 52. Specifically, the driving gear at the end of the transmission shaft of the servo motor 97 drives the driven gear at one end of the rotating shaft 98 to realize the rotation of the rotating shaft 98, and the rotating shaft 98 is fixedly connected with the electric cover plate 56 and rotates relative to the limit hole or sleeve fixed at the outlet of the third discharge pipe section 52 (the limit hole or sleeve for installing the rotating shaft, that is, the two ends of the rotating shaft are inserted into the limit holes at its two ends or the rotating shaft is placed in the sleeve and the two ends of the rotating shaft extend out of the sleeve, and one end of the rotating shaft is connected to the transmission shaft of the servo motor, and the other end is limited by a plug pin or a limit ring 103 to prevent detachment), to complete the opening or closing of the electric cover plate 56. It should be noted that there are two limit holes and sleeves, which are respectively sleeved on the two ends of the rotating shaft 98.

[0055] To facilitate, self-service, and semi-automatic feeding, this embodiment uses the lever principle to achieve, specifically Figure 10The top of the shown feed bucket 47 is suspended at one end of a lever 61 through a lifting cable 60. A counterweight 62 is suspended at the other end of the lever 61. The lever support 63 is fixed to the top of the bracket 57 and is located on the other side away from the third discharge pipe section 52 (i.e., disposed on both sides of the bracket 57 in the length direction opposite to the third discharge pipe section 52). After the feed in the feed barrel 47 decreases, under the lifting action of the counterweight 62, it rises below the outlet of the third discharge pipe section 52.

[0056] A limiting and guiding ring 99 is provided on the side wall of the third discharge pipe section 52 for the lifting cable 60 to pass through, so as to limit and guide the movement range of the lifting cable 60, making the inlet of the feed bucket 47 located below the outlet of the third discharge pipe section 52 when at rest, facilitating the feed to fall in. After the feed in the feed bucket 47 decreases, it will move upward below the third discharge pipe section 52 under the downward pull of the counterweight 62. Under the limiting and guiding action of the limiting and guiding ring 99, the top opening of the feed bucket 47 (using a mature feed bucket, which is composed of a feed basin at the bottom and a vertical feed guiding member fixedly connected to the retaining ring of the feed basin. The vertical feed guiding member is composed of a dome at the top and 5 circumferentially evenly distributed arc-shaped guiding vanes fixedly connected to the periphery of the bottom surface of the dome. In this embodiment, a hanging ring is provided at the top of the dome and is connected to the lifting cable 60) is directly opposite to the outlet of the third discharge pipe section 52. At this time, the electric cover plate 56 is opened to release the feed, and the release amount of the feed needs to be set in advance. Specifically, the opening duration of the electric cover plate 56 is set, and when the time is up, the electric cover plate 56 is closed to prevent the feed from being released. The opening and closing control of the electric cover plate 56 can adopt a mature timing control circuit, such as purchasing a ready-made timing switch and connecting it in series in the power supply circuit of the electric cover plate 56. Since the feed addition in this embodiment is a semi-automatic design, therefore, manual timing inspections are required. When it is found that a feed bucket 47 is lifted upward, the timing switch is manually turned on. When it runs to the set duration, the timing switch automatically closes the electric cover plate. When it is turned on again, the timing switch still needs to be manually turned on. Of course, the operation of manually turning on all the electric cover plates 56 with the same timing switch can also be adopted. This is mainly set based on timed feeding to reduce the operation frequency. After more than 90% of the feed buckets are pulled up, then manually operate the timing switch (mainly a delay-off switch) to open the electric cover plate.

[0057] A Figure 13 shown pulling spring 100 is connected between the top of the feed bucket 47 and the third discharge pipe section 52, maintaining a tendency to pull the feed bucket 47 towards the outlet of the third discharge pipe section 52; the other end of the lever 61 and the counterweight 62 are placed in a Figure 14 、 15Within the shown arc-shaped vertical guiding groove 101 to prevent the lateral swing of the lever 61; the top end of the arc-shaped vertical guiding groove 101 is fixed to the top of the shed body 1, and both sides of the notch of the arc-shaped vertical guiding groove 101 are fixedly connected to the bracket 57 through a transverse connecting rod 102 respectively (specifically in this embodiment, the transverse connecting rod 102 is connected between the lower ends of both sides of the notch of the arc-shaped vertical guiding groove 101 and the bracket 57); the lower end of the arc-shaped vertical guiding groove 101 extends to the lowest position of the counterweight 62 or lower than this lowest position to ensure that the counterweight 62 is always guided by the arc-shaped vertical guiding groove 101 and ensure the stability of its longitudinal movement and greatly reduce the lateral swing. For this reason, the arc-shaped vertical guiding groove 101 provided in this embodiment is parallel to the sliding track of the counterweight 62, that is, the groove surface 103 is parallel to the sliding track of the counterweight 62; the groove depth of the arc-shaped vertical guiding groove 101 covers at least two-thirds of the width of the sliding track, so as to form an effective lateral limit for the counterweight 62. Of course, according to the situation, one-third or one-half of the width of the counterweight 62 can be blocked. In this embodiment, two-thirds of its width is selected to obtain relatively more stable lateral blocking and limiting functions. How many fractions of the width need to be blocked in practice still needs to be finally determined through multiple experiments. After all, there are many influencing factors in practice, such as the thickness, material, flexibility of the rope, the thickness and material of the lever, and the way of the fulcrum (ball seat, bearing, rotating shaft, etc.) will all affect the lifting speed and lateral swing amplitude of the counterweight.

The movable plate 69 is propped up by the elastic support rod 70 to make it in a horizontal state, that is, coplanar with the bottom plate. When harvesting eggs, manually pull out the elastic support rod 70 from the blind hole 71 and rotate it to one side to release the propping of the movable plate 69, so that the movable plate 69 tilts downward toward the egg bracket 68 side, facilitating the eggs to roll onto the egg bracket 68. And in order to protect the eggs, in this embodiment, an egg-laying soft pad is fixed on the top surface of the movable plate 69, and a guiding channel surface 72 is provided outside the egg-laying soft pad to facilitate the eggs to roll out along the guiding channel surface 72.
