Description

Technical Field

[0001] The invention belongs to the technical field of mobile breeding and feeding, and particularly relates to a mobile pig house and an application thereof in allowing pigs to eat tail vegetables. Background Art

[0002] Mobile farming and feeding using existing mobile piggeries essentially relies on pelleted feed, or mixing pellets for liquid feeding. There are no mobile piggeries capable of feeding liquid feed. With rising agricultural product prices in recent years, feed prices have also been rising, leading to a continuous increase in the cost of slaughtering pigs in my country's aquaculture industry. In large-scale vegetable growing areas, a large amount of waste vegetables is produced every year. These waste vegetables also contain a large amount of nutrients, but they are currently not fully utilized. Therefore, it is necessary to develop a mobile farming and feeding technology that can fully utilize waste vegetables and combine waste vegetables with liquid feeding.

[0003] Existing document CN118266406A discloses a track-mounted modular, mobile, environmentally friendly pig house, comprising a pig house module, a deodorization module, and a mobile module. The mobile module is mounted at the bottom of the pig house module and the deodorization module, respectively. The pig house module and the deodorization module are separate, mutually affixed structures. The pig house module includes a main body, mobile traction columns, roof solar panels, wall solar panels, aisles, manure trenches, stainless steel mesh slatted panels, etc. Although this pig house is mobile, it is not suitable for large-scale vegetable cultivation areas, and it is even more inconvenient to collect leftover vegetables for feeding.

[0004] More importantly, the technical difficulties faced during mobile breeding and feeding include: it is difficult to evenly and quickly distribute the tail food to the pig feeding area of the mobile pig house. In particular, the existing solution relies on manual entry into the mobile pig house to feed the pigs, which is time-consuming, labor-intensive and extremely inconvenient. Summary of the Invention

The liquid feed dispenser 90 is used to dispense liquid feed. A movable drag chain 100 is installed on the side; a mesh is fixedly installed around the pig house frame 30, and a door panel 110 is installed on one side, the front and the back of the pig house frame 30 through hydraulic drive. A ventilation window 120 is embedded on the surface of the door panel 110, and a fence 130 is fixedly installed around the bottom frame 10. The bottom frame 10 and the fence 130 form a manure collection room. A manure discharge valve 140 is fixedly installed on the side of the manure collection room, and a manure scraping assembly is provided inside the manure collection room; the cross section of the horizontal frame 20 is Y-shaped, and a gate is hinged on one side of the fence 50. A photovoltaic panel power generation system is fixedly installed on the top of the pig house frame 30; the manure scraping assembly includes a herringbone board 150 , the herringbone plate 150 is fixedly installed at the bottom of the cross frame 20, and the side plates 151 are fixedly installed at both ends of the herringbone plate 150, and the side plates 151 are fixedly installed to the inner wall of the bottom frame 10; a reciprocating screw rod 152 is rotatably installed between the two side plates 151, and one end of the reciprocating screw rod 152 is fixedly installed to the output end of the servo motor 153, and the servo motor 153 is fixedly installed on the side of the side plate 151; the outer side of the reciprocating screw rod 152 is threadedly connected to a screw rod sleeve 154, and pressure sensors 155 are embedded on both sides of the screw rod sleeve 154. An intermediate plate 156 is fixedly installed on the outer side of the screw rod sleeve 154, and the bottom of the intermediate plate 156 is movably installed through a hinge shaft 157 There is a scraper 158, which fits together with the bottom wall of the manure collection room, and a limit plate 159 is fixedly installed on the back of the middle plate 156 to limit the scraper 158; one end of the screw sleeve 154 is fixedly sleeved with a ring plate 1510, and extension rods 1511 are fixedly installed on both sides of the ring plate 1510, and the other end of the extension rod 1511 is fixedly installed with an oblique scraping strip 1512, which fits on the outer surface of the herringbone plate 150; the side of the ring plate 1510 is hinged with an electric push rod 1513, and the other end of the electric push rod 1513 is hinged on the vertical plate 1514, and the vertical plate 1514 is fixedly installed in the middle section of the top of the scraper 158.

[0025] When scraping feces, the servo motor 153 drives the reciprocating screw 152 to rotate, and the reciprocating screw 152 drives the screw sleeve 154, the middle plate 156, the scraper 158 and the oblique scraping bar 1512 to move back and forth. The scraper 158 can scrape the feces on the bottom wall of the feces collection room and push it to the extension pipe of the feces discharge valve 140 for easy discharge; the oblique scraping bar 1512 can scrape off the residue on the top of the herringbone plate 150 to reduce the hardening of feces. When the scraper 158 returns to its original position, it is pushed by the electric push rod 1513 The vertical plate 1514 rotates around the hinge 157, and then the scraper 158 rotates from vertical to horizontal. This ensures that when the scraper 158 returns to its original position, it will not push the residual feces into the deep of the feces collection room. The electric push rod 1513 is then used to pull the scraper 158 back to the vertical state, which is convenient for the next feces scraping process. When the scraper 158 moves to push the feces, the scraper 158 is resisted by the limit plate 159, ensuring that the scraper 158 does not tilt excessively due to the increased resistance after scraping a lot of feces, thereby achieving rapid feces discharge. Among them, when the reciprocating screw 152 removes the screw sleeve 154 and moves to the end of the screw, the pressure sensor 155 is pressed against the side plate 151 or the servo motor 153, and then the PLC controller will control the servo motor 153 to stop running or flip. When the scraper 158 returns to its original position, the PLC controller will also control the electric push rod 1513 to extend, allowing the scraper 158 to rotate horizontally. When in use, the feces and urine excreted by the pigs are collected, that is, in the manure collection room below the grid plate 40. A manure discharge valve 140 is reserved at the end of the manure collection room below. The manure can be led out through the interface of the manure discharge valve 140. When the mobile pig house is moved to a place with poor soil fertility, the manure can be led out and fermented to provide organic fertilizer to local farmers or fields.

[0026] In this embodiment, the mobile pig house is used to feed pigs with leftover vegetables. The mobile pig house is moved to a field with leftover vegetables, and the leftover vegetables are collected and fed to a feeding structure 11. The feeding structure 11 moves the leftover vegetables to a cutting part 12, chops them up, and feeds them to the pigs. The steps of chopping the leftover vegetables and feeding them to the pigs include: Step 1: When all movable plates 5 are in the initial state, the leftover vegetables are chopped until the strip space 3 is filled with chopped leftover vegetable scraps 56. The state at this time is as follows: Figure 5 As shown in the middle left picture; Step 2, at the time when the pigs are eating, the winding mechanism corresponding to the first movable plate 51 at the top is controlled to operate, and the first movable plate 51 is moved down to the target height 1. At this time, part of the tail vegetable scraps 56 on the side of the first movable plate 51 automatically falls into the feeding trough 80 for the pigs to eat. The state at this time is as follows: Figure 5 As shown in the middle picture; Step 3, when the feeding in step 2 is completed, the winding mechanism corresponding to the first movable plate 51 and the second movable plate 52 is controlled to operate, and the first movable plate 51 and the second movable plate 52 are moved down to the target height 2. At this time, part of the tail vegetable scraps 56 on the side of the second movable plate 52 automatically falls into the feeding trough 80 to continue to be fed by the pigs. The state at this time is as follows: Figure 5 As shown in the right figure; While the tail vegetable scraps 56 are falling, the liquid feed dispenser 90 is controlled to work according to the set liquid feed delivery amount, and the liquid feed is delivered into the feeding trough 80 together, thereby achieving the joint feeding of the liquid feed and the tail vegetable; Step 4: After the feeding in step 3 is completed, the winding mechanisms corresponding to the first to third movable plates 51, 53 are controlled to operate, and the first to third movable plates 51, 53 are moved down to the target height N. At this time, part of the leftover vegetable scraps 56 on the side of the third movable plate 53 automatically falls into the trough 80 to continue to be fed by the pigs; Step 5. After the feeding in step 4 is completed, the winding mechanism corresponding to the first movable plate 51 to the fourth movable plate 54 is controlled to operate, and the first movable plate 51 to the fourth movable plate 54 are moved down to the target height N. At this time, part of the tail vegetable scraps 56 on the side of the fourth movable plate 54 automatically falls into the trough 80 to continue to be fed by the pigs.

[0027] Example 2, referring to Example 1, differs from Example 1 in that: Figure 15 As shown, each movable plate 5 is vertically provided with two through holes, each through hole is penetrated by a steel rope 9 in a straight state, the upper end of the steel rope 9 is fixedly connected to the top of the pen, and the lower end of the steel rope 9 is connected to the bottom of the pen, and the rope 6 is located between the two steel ropes 9. The use of such a structure mainly plays the role of stably storing the tail vegetable shreds in the strip space, facilitating the stable and smooth delivery of the tail vegetable shreds, and convenient feeding.

[0028] The present invention combines movable vehicle body with pen house, realizes mobile breeding and feeding in this real sense, is convenient to fully recycle vegetable tail leaf and feed in each large vegetable growing area, can easily, easily, stably be put into the pig feeding area of mobile pig house quickly, does not need to manually enter mobile pig house and feed, saves time and energy. In the traditional scheme of manually feeding the tail vegetable shreds, it takes thirty minutes to evenly put a fixed amount (one hundred kilograms) of tail vegetable shreds into the feeding trough (ten meters in length). However, the scheme of Example 1 only takes less than one minute to achieve uniform feeding and does not require manual operation, which is very convenient, time-saving and labor-saving.
