Description

Technical Field

[0001] The invention relates to the technical field of pig farming in pig farms, and in particular to a piggery with a function of preventing turbid air from flowing back. Background Art

[0002] Pig houses are usually divided into different zones according to the different growth stages and uses of pigs, such as boar houses, breeding houses, farrowing and lactation houses, nursery houses, fattening houses and isolation houses, etc. This type of zone management helps to achieve refined management and improve breeding efficiency.

[0003] When raising pigs in nursery or fattening pig houses, the odor in the manure ditch may flow back into the pig house, which may have many negative effects on pig farming. For example, the foul air in the pig house, such as ammonia, will directly bind to the pig's hemoglobin, resulting in a decrease in the oxygen that the hemoglobin can bind to, an increase in the blood ammonia concentration, and an impact on the synthesis of protein and normal metabolism in the pig's body, thereby reducing the pig's growth rate and slowing down its growth. Harmful gases such as ammonia can also affect the formation of immunoglobulins in the blood, reduce the pig's immunity, and make it more susceptible to infection by pathogens.

[0036] refer to Figures 1 to 14 The present invention provides a pig house with a function of preventing turbid air from flowing back, including a pig house frame 1, wherein the pig house frame 1 includes a support plate 104 on which a plurality of manure-leaking plates 102 are installed and side baffles 101 located on both sides of the pig house frame 1, wherein a working cavity 401 is arranged at the bottom end of the support plate 104, and a feces collecting cavity 402 is arranged at the bottom end of the manure-leaking plates 102, wherein a main ventilation duct 3 for conducting external air is arranged inside the pig house frame 1, and a side of the main ventilation duct 3 is arranged for controlling the flow of gas to the feces collecting cavity 40 2, a driving push plate 2 for driving pigs is arranged at the top of the support plate 104, the driving push plate 2 is vertically arranged between the two side baffles 101, a horizontal pushing mechanism is arranged inside the working cavity 401 for driving the driving push plate 2 to slide along the length direction of the side baffle 101, a plurality of adjusting blocks 8 for reducing the leakage of turbid air are arranged inside the feces collection cavity 402, and a rotating swing mechanism for controlling the inclination angle of the adjusting block 8 is arranged outside the feces collection cavity 402.

[0037] In the process of raising pigs in a nursery pig house or a fattening pig house, the diet of the pigs is monitored and controlled, and the pigs are driven into the pig house during the excretion cycle so that they can excrete in this area. During the excretion process, the block 8 is adjusted to be in an open state, and the feces can be directly discharged into the feces collection chamber 402. After the excretion cycle is over, the driving push plate 2 is controlled to be pushed inward synchronously, and the block 8 is adjusted to be closed to prevent turbid air from flowing out of the slatted plate 102. At the same time, the pigs can be driven to the middle channel, so that the pigs move in a specified direction and move along the middle channel to the specified position, which is convenient for control. The moving path of the pigs, multiple adjacent driving push plates 2 can be connected by extending baffles to prevent the pigs from running out along the gaps, and the driving push plates 2 move inwards to facilitate the cleaning of the manure-leaking plate 102. The bottom of the manure-leaking plate 102 is provided with an adjustment block 8 for blocking the holes of the manure-leaking plate 102. By making the adjustment block 8 fit with the manure-leaking plate 102 for a long time, the turbid air inside the feces collection cavity 402 is reduced from drifting outwards. By setting the inner ventilation duct 302, the hollow channel 801 can be ventilated, and the turbid air is further prevented from drifting outwards to enhance the effect of preventing the turbid air from leaking out. When cleaning the feces on the surface of the manure-leaking plate 102, the driving push plate 2 is driven inwards by the threaded rod 6, so that the adjustment block 8 can be changed from a horizontal state to an inclined state, which is convenient for flushing the support plate 104 and the manure-leaking plate 102.

[0038] It also includes a synchronous connection mechanism, which includes a transmission gear 601, a sliding adjustment component 11, a transmission component 12, a transmission shaft 7 and a synchronous chain component three 10. The horizontal pushing mechanism includes a threaded rod 6 that can rotate, and the transmission gear 601 is installed at the end of the threaded rod 6. The sliding adjustment component 11 includes a guide seat 1107, a sliding adjustment rod 1106, a bearing 1102, a gear two 1101, a drive ring 1103 and an elastic reset seat. The guide seat 1107 is fixedly installed on the inner side of the working cavity 401, and the sliding adjustment rod 1106 can be installed on the guide seat 1107 in a horizontally slidable manner. The outer side of the sliding adjustment rod 1106 is fixedly connected to the inner edge of the bearing 1102, and the gear two 1101 is fixedly installed on the outer side of the bearing 1102. Installed on the pig house frame 1, one side of the transmission component 12 is connected to the transmission shaft 7, and an adjusting slider 201 is fixedly set at the bottom of the driving push plate 2. The adjusting slider 201 is used to push the driving ring 1103. The adjusting slider 201 is provided with an avoidance groove 202 for avoiding the guide seat 1107. The driving ring 1103 is fixedly connected to the sliding adjustment rod 1106, and the elastic reset seat is fixedly installed on the sliding adjustment rod 1106. The elastic reset seat is used to apply an elastic force to the sliding adjustment rod 1106 away from the transmission gear 601. The transmission shaft 7 is used to drive the synchronous chain components three 10 on both sides to rotate. The synchronous chain components three 10 can drive the rotating and swinging mechanism to rotate. The transmission shaft 7 is connected to the ventilation connection mechanism; the synchronous connection mechanism is used to control the transmission of multiple components inside the pig house.

[0039] When the adjusting slider 201 is not in contact with the driving ring 1103 , the gear 2 1101 is separated from the transmission gear 601 and the transmission assembly 12 ; the rotation of the threaded rod 6 cannot drive the sliding adjusting rod 1106 below to rotate.

[0040] When the adjusting slider 201 is fitted with the driving ring 1103 and is pushed to the final position, the sliding adjusting rod 1106 slides to one side, the limit block 1105 is separated from the gear three 1201, and the gear two 1101 is in transmission connection with the transmission gear 601 and the transmission assembly 12. The final position is a specified distance that the sliding adjusting rod 1106 slides to one side, which can ensure that the transmission with the transmission gear 601 and the transmission assembly 12 is maintained during the sliding process of the gear two 1101.

[0041] One end of the sliding adjustment rod 1106 may be provided with a plurality of rectangular blocks that can prevent it from rotating, so as to prevent the sliding adjustment rod 1106 from rotating when the limit block 1105 is engaged with the synchronous connection mechanism, thereby reducing the transmission accuracy and causing motion errors.

[0042] The driving push plate 2 starts from contacting the avoidance groove 202 with the driving ring 1103 and ends when the driving push plate 2 slides inward to the end. While the sliding adjustment rod 1106 slides inward, the gear 2 1101 and the gear 3 1201 on the outside of the bearing 1102 remain in meshing state.

[0043] The transmission assembly 12 includes a rotating shaft 1204 rotatably mounted on one side of the working chamber 401, a gear three 1201 fixedly mounted on the outer wall of the rotating shaft 1204, and a first bevel gear 1202 located at the end of the rotating shaft 1204. The gear three 1201 can mesh with the gear two 1101. The second bevel gear 1203 meshing with the first bevel gear 1202 is installed at one end of the transmission shaft 7 close to the transmission assembly 12. The first bevel gear 1202 is used to drive the transmission shaft 7 to rotate synchronously.

[0044] The horizontal pushing mechanism also includes a synchronous chain assembly 5 for controlling the synchronous rotation of the threaded rods 6 on both sides and a motor installed on one side of one of the threaded rods 6 and used to drive the rotation thereof. The top of the support plate 104 is provided with a guide groove 103 for avoiding the sliding of the driving push plate 2. The adjusting slider 201 is located on both sides of the driving push plate 2 and extends through the guide groove 103 to the inside of the working cavity 401. The adjusting slider 201 is threadedly connected with the threaded rod 6. The guide groove 103 can be covered to prevent feces from falling into the inside of the working cavity 401 along the guide groove 103, causing the feces to affect the use of the transmission mechanism. At the same time, the driving push plate 2 can be equipped with a flushing device. During use, multiple pig house frames 1 are placed at equal distances to form a pig house together.

[0045] The rotating and swinging mechanism includes a synchronous chain assembly 29 located on both sides of the feces collection cavity 402, and multiple connecting shafts 13 are rotatably installed on both sides of the feces collection cavity 402. The outer side of the connecting shaft 13 is fixedly connected to the synchronous chain assembly 29, and the inner side of the connecting shaft 13 is fixedly connected to the adjusting block 8. The connecting shaft 13 is rotatably connected to the feces collection cavity 402.

[0046] When the adjusting slider 201 starts to contact with the driving ring 1103 and continues to be pushed to the final position, the adjusting block 8 changes from a horizontal state to an inclined state.

[0047] When the push plate 2 is driven to slide from the inside to the outside, the threaded rod 6 rotates clockwise, the avoidance groove 202 separates from the drive ring 1103, and the reset spring 1104 drives the sliding adjustment rod 1106 to slide outward. When the reset spring 1104 drives the sliding adjustment rod 1106 to return to the initial position, the limit block 1105 engages with gear three 1201, driving the push plate 2 to slide from the inside to the outside. While the threaded rod 6 rotates, the transmission gear 601 drives gear two 1101 to rotate, and gear two 1101 drives the synchronous connection mechanism to transmit. The synchronous connection mechanism drives the synchronous chain assembly two 9 to rotate, and drives the adjustment block 8 to rotate. When the sliding adjustment rod 1106 slides outward until the gear two 1101 is separated from the synchronous connection mechanism, the multiple adjustment blocks 8 rotate from the inclined state to the horizontal state.

[0048] When the adjusting slider 201 slides from the inside to the outside until the gear 2 1101 is separated from the gear 3 1201 , the adjusting block 8 changes from the inclined state to the horizontal state.

[0049] The threaded rod 6 rotates counterclockwise, driving the adjusting slider 201 and the avoidance groove 202 to slide inward. The avoidance groove 202 can push the driving ring 1103 to slide inward. The driving ring 1103 drives the sliding adjustment rod 1106 to slide inward. The limit block 1105 is separated from the synchronous connection mechanism, and the gear 2 1101 is connected to the synchronous connection mechanism. The transmission gear 601 transmits the synchronous connection mechanism through the gear 2 1101. The synchronous connection mechanism drives the synchronous chain assembly 2 9 to rotate, so that the multiple adjustment blocks 8 rotate from the horizontal state to the inclined state.

[0050] The ventilation connection mechanism includes an inner ventilation duct 302, a windshield 303, a ventilation slot 304, a rack 305 and a gear 701. A vent 301 is provided inside the main ventilation duct 3. The inner ventilation duct 302 extends to the inside of the feces collection cavity 402 through the vent 301. The windshield 303 is used to control the flow of gas into the inner ventilation duct 302. The windshield 303 is inserted on one side of the inner ventilation duct 302. The windshield 303 is vertically slidably connected to the inner ventilation duct 302. The wind slot 304 is opened on the wind shield 303 and is used for gas circulation. The rack 305 is located on both sides of the wind shield 303. The gear 701 is fixedly mounted on the outer surface of the transmission shaft 7 and is meshed with the rack 305. The main ventilation duct 3 is connected to the pig farm fan, and the positive pressure and negative pressure inside the duct can be controlled. An exhaust channel can be provided inside the feces collection cavity 402. The wind shield 303 is inserted on the outside of the main ventilation duct 3, and one side of the wind shield 303 is in contact with the outer wall of the inner ventilation duct 302.

[0051] When the gear 1 701 drives the rack 305 to slide vertically upward to the final position, the wind shield 303 prevents air from flowing into the feces collection chamber 402 .

[0052] When gear 1 701 drives the rack 305 to slide vertically upward, the wind shield 303 prevents air from flowing into the interior of the feces collection chamber 402; when gear 3 1201 is meshed with gear 2 1101, if the threaded rod 6 rotates counterclockwise, the adjustment block 8 rotates from a horizontal state to an inclined state, the transmission shaft 7 rotates, and the gear 1 701 drives the rack 305 to slide vertically upward. The wind shield 303 slides upward, and the ventilation slot 304 cannot be connected with the internal ventilation duct 302, thereby preventing air from flowing into the feces collection chamber 402, thereby avoiding disturbing the turbid air inside the feces collection chamber 402 and causing the turbid air to leak out.

[0053] When the gear 1 701 drives the rack 305 to slide vertically downward to the final position, the ventilation slot 304 is connected to the inner ventilation duct 302 .

[0054] When the gear 1 701 drives the rack 305 to slide vertically downward, the ventilation slot 304 is connected to the inner ventilation duct 302. When the gear 3 1201 is meshed with the gear 2 1101, if the threaded rod 6 rotates clockwise, the adjustment block 8 rotates from the inclined state to the horizontal state, the transmission shaft 7 rotates, the gear 1 701 drives the rack 305 to slide vertically downward, and the windshield 303 slides downward to connect the ventilation slot 304 with the inner ventilation duct 302. When the adjustment block 8 is in the horizontal state, the inner ventilation duct 302 of the feces collection chamber 402 is in a working state, thereby reducing the probability of domestic pigs getting sick.

[0055] The elastic reset seat includes a reset spring 1104 and a retaining ring 1108. The retaining ring 1108 is fixedly installed on the outer side of the sliding adjustment rod 1106. One end of the reset spring 1104 is fixedly connected to the retaining ring 1108 and the other end is fixedly connected to the guide seat 1107. The reset spring 1104 applies elastic force to the retaining ring 1108, which can drive the sliding adjustment rod 1106 to slide outward, thereby driving the sliding adjustment rod 1106 to reset.

[0056] A hollow channel 801 is provided in the middle of the adjusting block 8, and the air outlet of the inner ventilation duct 302 corresponds to the hollow channel 801 in the horizontal state, and one of the sprockets of the synchronous chain assembly 2 9 and the synchronous chain assembly 3 10 is fixedly connected to the connecting shaft 13. The coaxial arrangement can ensure that multiple adjusting blocks 8 rotate synchronously, avoiding interference between adjacent adjusting blocks 8 during the rotation process or causing the adjusting blocks 8 to fail to fit with the slatted plate 102, resulting in leakage of foul air.

[0057] The sliding adjustment assembly 11 further includes a limit block 1105 located at the end of the sliding adjustment rod 1106 . When the limit block 1105 is engaged with the locking gear three 1201 , the limit block 1105 is used to lock the gear three 1201 .

[0058] When the reset spring 1104 drives the sliding adjustment rod 1106 to return to the initial position, the limit block 1105 engages with the gear three 1201 to prevent the synchronous connection mechanism from sliding, resulting in the adjustment block 8 being unable to accurately fit with the slatted floor 102.

[0059] The present invention, by setting a plurality of rotatable adjustment blocks 8 to block the holes of the manure-leaking plate 102 in batches, controls the flow direction of the foul air, and by opening a hollow channel 801 inside the adjustment block 8 and providing an internal ventilation duct 302, can prevent the foul air from drifting upward to the inside of the pig farm by ventilating the hollow channel 801; prevent harmful gases in the foul air from affecting the growth of pigs, thereby reducing the content of harmful gases in the pig farm. Thus, the probability of pigs getting sick is reduced; by setting the driving push plate 2, the difficulty of cleaning the pig house can be reduced. When the driving push plate 2 moves inward, the adjustment block 8 can be rotated to tilt, and the internal ventilation duct 302 can be closed, which is convenient for the maintenance and cleaning of the pig house and reduces the difficulty of cleaning. When the driving push plate 2 moves from the inside to the outside, the adjustment block 8 can be rotated to be horizontal, and the internal ventilation duct 302 can be opened. While preventing the leakage of foul air, the ventilation effect inside the feces collection cavity 402 is ensured, and the content and concentration of harmful gases are reduced, thereby improving the breeding environment quality of the pig house and the health of the pig herd, and reducing the spread of diseases.
