Description

Technical Field

[0001] This invention belongs to the field of mobile farming and feeding technology, specifically relating to a mobile pigsty and its application in pigs consuming vegetable waste. Background Technology

[0002] Currently, mobile pig farming and feeding primarily rely on pelleted feed or a mixture of pellets and liquid feed; there are no mobile pig farms capable of feeding liquid feed. In large-scale vegetable growing areas, a large amount of vegetable waste is generated annually, containing significant nutrients that are not currently being fully utilized. Therefore, it is necessary to develop a mobile farming and feeding technology that can fully utilize vegetable waste and combine it with liquid feeding.

[0003] Existing literature CN118266406A discloses a track-mounted modular mobile environmentally friendly pigsty, including a pigsty module, a deodorization module, and a moving module. The moving module is located at the bottom of both the pigsty module and the deodorization module. The pigsty module and the deodorization module are separate structures that fit together. The pigsty module includes the main body of the pigsty, a moving traction column, roof solar panels, wall solar panels, a passageway, a manure ditch, and a stainless steel mesh slatted panel. Although this pigsty is mobile, it is not suitable for application in large-scale vegetable growing areas, and it is inconvenient to collect vegetable waste for feeding.

[0004] More importantly, the technical challenges faced in mobile farming and feeding include: it is difficult to evenly and quickly distribute leftover vegetables to the feeding area of ​​pigs in the mobile pigsty, especially since the existing methods rely on manual feeding into the mobile pigsty, which is time-consuming, labor-intensive, and extremely inconvenient. Summary of the Invention

[0005] At least in response to the problems mentioned in the background art, the present invention aims to provide a mobile pigsty and its application in pigs' consumption of vegetable waste, which can make full use of vegetable waste and combine it with liquid feeding.

[0006] The present invention adopts the following technical solution.

[0007] A mobile pigsty includes a vehicle body and a pen structure mounted on the vehicle body. The vehicle body is a trailer or truck, and the pen structure can move with the vehicle body. The pen structure includes a first pen and a second pen arranged symmetrically. A strip space for containing vegetable scraps is provided between the first pen and the second pen. A vegetable scrap chopping mechanism is provided above the strip space. The side panels of the strip space are vertically arranged telescopic plate assemblies, and the vegetable scraps in the strip space can fall into the pen for the pigs to eat.

[0008] Preferably, the length of the strip space is basically the same as the length of the enclosure, the height of the strip space is 10-20cm less than the height of the enclosure, and both ends of the strip space can be closed.

[0009] Furthermore, the telescopic panel assembly includes several staggered and closely arranged movable panels. Each movable panel is connected to a winding mechanism via ropes. The lower movable panels are closer to the center line of the strip space, while the upper movable panels are farther away from the center line. In the initial state, all the movable panels on the same side of the strip space together form a stepped structure. Using this design, leftover food can be easily and quickly distributed evenly and quickly to the pigs' feeding area in the mobile pigsty.

[0010] Preferably, a feeding trough is provided inside the enclosure and on the side near the telescopic plate assembly, with the length direction of the feeding trough aligned with the length direction of the strip space.

[0011] In order to more accurately dispose of leftover vegetable scraps, the feeding trough is attached to the base of the telescopic plate assembly, and the top of the movable plate is located above the feeding trough in the initial state.

[0012] Furthermore, each movable plate has its two ends fitted into a limiting groove; alternatively, each movable plate has two vertically oriented through holes, each through hole through which a taut steel rope is threaded. The upper end of the steel rope is fixedly connected to the top of the enclosure, and the lower end is connected to the bottom of the enclosure, with the rope positioned between the two steel ropes. This design allows for stable temporary storage of vegetable scraps within the strip-shaped space, facilitates stable placement of vegetable scraps, and makes feeding convenient.

[0013] Furthermore, the vegetable waste chopping mechanism includes a feeding structure installed on the outer wall of the pen structure, with a cutting section at the end of the feeding structure; the feeding structure includes a trough, which is installed between adjacent ventilation windows on the outer wall of the pen structure, and multiple rollers capable of circulating within the trough are installed, each roller being equipped with a claw / cone, the circulating rollers and claws driving the vegetable waste leaves in the trough to continuously move forward, and when the vegetable waste leaves move forward to below the blades of the cutting section, the blades chop the vegetable waste leaves.

[0014] Furthermore, each pen structure includes a base frame, a crossbeam fixedly installed on the top of the base frame, a pigpen frame fixedly installed on the top of the crossbeam, a grid plate fixedly installed on the bottom wall of the pigpen frame, a fence fixedly installed on the inner bottom wall of the pigpen frame, an installation frame fixedly installed on the top of the pigpen frame and on the side of the fence, a canopy fixedly installed on the top of the installation frame, a feed trough fixedly installed on the bottom of the installation frame, a liquid feed dispenser slidably installed on the middle section of the installation frame via a slide bar, and a movable drag chain movably installed on one side of the liquid feed dispenser; a mesh screen fixedly installed around the pigpen frame, and doors installed on one side, the front and back of the pigpen frame via hydraulic drive, with ventilation windows embedded on the surface of the doors; a perimeter panel fixedly installed around the base frame, the base frame and the perimeter panel forming a manure collection chamber, a manure discharge valve (140) fixedly installed on the side of the manure collection chamber, and a manure scraping assembly installed inside the manure collection chamber; the crossbeam has a Y-shaped cross section, a door hinged to one side of the fence, and the top of the pigpen frame is fixedly... A photovoltaic power generation system is installed; the manure scraping assembly includes a herringbone plate, which is fixedly installed at the bottom of the cross frame. Side plates are fixedly installed at both ends of the herringbone plate, and the side plates are fixedly installed to the inner wall of the bottom frame. A reciprocating screw is rotatably installed between the two side plates. One end of the reciprocating screw is fixedly installed to the output end of a servo motor, and the servo motor is fixedly installed on the side of the side plate. A screw sleeve is threaded to the outside of the reciprocating screw. Pressure sensors are embedded on both sides of the screw sleeve. A middle plate is fixedly installed on the outside of the screw sleeve. A scraper is movably installed at the bottom of the middle plate through a hinge. The scraper is in contact with the bottom wall of the manure collection chamber. A limiting plate is fixedly installed on the back of the middle plate to restrict the scraper. A ring plate is fixedly fitted at one end of the screw sleeve. Extension rods are fixedly installed on both sides of the ring plate. An oblique scraper is fixedly installed at the other end of the extension rod. The oblique scraper is in contact with the outer surface of the herringbone plate. An electric push rod is hinged to the side of the ring plate. The other end of the electric push rod is hinged to a vertical plate. The vertical plate is fixedly installed in the middle section of the top of the scraper.

[0015] In this invention, an application of the aforementioned mobile pigsty in feeding pigs with vegetable waste involves moving the mobile pigsty to a field with vegetable waste, collecting the waste and feeding it into a feeding structure. The feeding structure then moves the waste to a cutting section, where it is chopped and fed to the pigs.

[0016] Furthermore, the steps of chopping the vegetable scraps and feeding them to the pigs include: Step 1: When all moving plates are in the initial state, perform the chopping of leftover vegetables until the strip space is filled with chopped leftover vegetable scraps; Step 2: At the time when the pigs are feeding, control the operation of the winding mechanism corresponding to the first movable plate at the top to move the first movable plate down to the target height. At this time, some of the leftover vegetable scraps on the side of the first movable plate will automatically fall into the feeding trough for the pigs to eat. Step 3: After feeding in Step 2 is completed, control the winding mechanism corresponding to the first and second movable plates to move the first and second movable plates down to the target height 2. At this time, some leftover vegetable scraps on the side of the second movable plate will automatically fall into the trough to continue feeding the pigs. As the vegetable scraps fall, the liquid feed dispenser is controlled to dispense liquid feed into the trough according to the set amount, thus enabling the liquid feed and vegetable scraps to be fed together. Step 4: Control the winding mechanism corresponding to the first to the Nth movable plates to move the first to the Nth movable plates down to the target height N. At this time, some leftover vegetable scraps on the side of the Nth movable plate will automatically fall into the feeding trough to continue feeding the pigs. N = 3, 4, 5, 6, 7 or 8.

[0017] Beneficial effects: This invention combines a mobile vehicle body with a pigpen, realizing mobile breeding and feeding, facilitating the full recycling and utilization of vegetable waste for feeding in various vegetable planting areas; using this invention, vegetable waste can be easily, conveniently, and stably and evenly and quickly placed in the pigs' feeding area in the mobile pigpen, without the need for manual entry into the mobile pigpen for feeding. Saves time and effort. Attached Figure Description

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] Combination Figures 1 to 14 As shown, a mobile pigsty includes a vehicle body and a pen structure mounted on the vehicle body. The vehicle body is a trailer, and the pen structure can move with the vehicle body. The pen structure includes a first pen 1 and a second pen 2 arranged symmetrically. A strip-shaped space 3 for accommodating leftover vegetable scraps is provided between the first pen 1 and the second pen 2. A leftover vegetable chopping mechanism is provided above the strip-shaped space 3. The side panels of the strip-shaped space 3 are vertically arranged telescopic plate assemblies, allowing the leftover vegetable scraps in the strip-shaped space 3 to fall into the pen for the pigs to eat. The length of the strip-shaped space 3 is basically the same as the length of the pen, and the height of the strip-shaped space 3 is 10-20 cm less than the height of the pen. Both ends of the strip-shaped space 3 can be closed by door panels 16.

[0022] In this embodiment, combined with Figures 2 to 5As shown, the telescopic plate assembly includes four staggered and closely arranged movable plates 5 (including the first movable plate 51, the second movable plate 52, the third movable plate 53, and the fourth movable plate 54 arranged sequentially from bottom to top). Each movable plate 5 is connected to a winding mechanism 7 via a rope 6. The movable plate 5 located at the bottom is closer to the center line of the strip space 3, while the movable plate 5 located at the top is farther away from the center line of the strip space 3. In the initial state, all the movable plates 5 on the same side of the strip space 3 together form a stepped structure. This variable strip space 3, which is wider at the top and narrower at the bottom and can be height-adjusted, is not only conducive to collecting vegetable scraps but also to feeding the vegetable scraps to the pigs smoothly. The gaps at both ends of each movable plate 5 fit into the limiting groove 4. A feeding trough 80 is provided in the pen and on the side close to the telescopic plate assembly. The length direction of the feeding trough 80 is consistent with the length direction of the strip space 3. The feeding trough 80 is attached to the root of the telescopic plate assembly, and in the initial state, the top of the movable plate 5 is above the feeding trough 80. Among them, a triangular body 55 is provided on the bottom inner side of the fourth movable plate 54. The angle between the slope of the triangular body 55 and the horizontal plane is 50°. The lowest point of the slope of the triangular body 55 is located at the bottom of the fourth movable plate 54. Its function is to facilitate all the leftover vegetable scraps 56 in the strip space 3 to fall smoothly into the feeding trough 80 when all four movable plates 5 have fallen to the lower limit position.

[0023] In this embodiment, the vegetable waste chopping mechanism includes multiple feeding structures 11 disposed on the outer wall of the pen structure. Each feeding structure 11 has a cutting section 12 at its end, and the distance between adjacent feeding structures 11 is 60cm. The feeding structure 11 includes a trough 13, which is disposed between adjacent ventilation windows / vents on the outer wall of the pen structure (to facilitate the collection of vegetable waste and the even distribution of vegetable waste shreds). Rollers 14 capable of circulating operation are disposed in the trough 13. Multiple rollers 14 are arranged at intervals and in parallel. Each roller 14 is provided with a claw 15 (or cone). The circulating (rotating) rollers 14 and claws 15 drive the vegetable waste shreds in the trough 13 to move forward continuously. When the vegetable waste shreds move forward to below the blade of the cutting section 12, the blade shreds the vegetable waste shreds.

[0024] In this embodiment, combined with Figures 6 to 14As shown, the pen structure includes a base frame 10, a crossbeam 20 fixedly installed on the top of the base frame 10, a pigpen frame 30 fixedly installed on the top of the crossbeam 20, a grid panel 40 fixedly installed on the bottom wall of the pigpen frame 30, a fence 50 fixedly installed on the inner bottom wall of the pigpen frame 30, an installation frame 60 fixedly installed on the top of the pigpen frame 30 and on the side of the fence 50, a canopy 70 fixedly installed on the top of the installation frame 60, a feeding trough 80 fixedly installed on the bottom of the installation frame 60, and a liquid feed dispenser 90 slidably installed in the middle section of the installation frame 60 via a sliding rod. The liquid feed dispenser 90 is used to dispense liquid feed. A movable drag chain 100 is installed on the side; a mesh screen is fixedly installed around the pigsty frame 30; door panels 110 are hydraulically driven to be installed on one side, the front, and the back of the pigsty frame 30; ventilation windows 120 are embedded in the surface of the door panels 110; a surrounding panel 130 is fixedly installed around the bottom frame 10; the bottom frame 10 and the surrounding panel 130 form a manure collection chamber; a manure discharge valve 140 is fixedly installed on the side of the manure collection chamber; a manure scraping assembly is installed inside the manure collection chamber; the cross-section of the horizontal frame 20 is Y-shaped; a door is hinged to one side of the fence 50; a photovoltaic power generation system is fixedly installed on the top of the pigsty frame 30; the manure scraping assembly includes a herringbone panel 150. A herringbone plate 150 is fixedly installed at the bottom of the cross frame 20. 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 152 is rotatably installed between the two side plates 151. One end of the reciprocating screw 152 is fixedly installed to the output end of a servo motor 153, which is fixedly installed on the side of the side plate 151. A screw sleeve 154 is threaded onto the outer side of the reciprocating screw 152. Pressure sensors 155 are embedded on both sides of the screw sleeve 154. A middle plate 156 is fixedly installed on the outer side of the screw sleeve 154, and the bottom of the middle plate 156 is movably installed via a hinge pin 157. There is a scraper 158, which is in contact with the bottom wall of the manure collection chamber. A limiting plate 159 is fixedly installed on the back of the intermediate plate 156 to restrict the scraper 158. A ring plate 1510 is fixedly installed on one end of the screw sleeve 154. Extension rods 1511 are fixedly installed on both sides of the ring plate 1510. An oblique scraper 1512 is fixedly installed on the other end of the extension rod 1511. The oblique scraper 1512 is attached to the outer surface of the herringbone plate 150. An electric push rod 1513 is hinged to the side of the ring plate 1510. The other end of the electric push rod 1513 is hinged to the vertical plate 1514. The vertical plate 1514 is fixedly installed in the middle section of the top of the scraper 158.

[0025] During scraping, the servo motor 153 drives the reciprocating screw 152 to rotate. The reciprocating screw 152 then drives the screw sleeve 154, intermediate plate 156, scraper 158, and inclined scraper 1512 to move back and forth. The scraper 158 can scrape and push the feces on the bottom wall of the feces collection chamber to the vicinity of the extension pipe of the discharge valve 140 for easy discharge. The inclined scraper 1512 can scrape off the residue on the top of the herringbone plate 150 to reduce fecal hardening. 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 shaft 157, causing the scraper 158 to rotate from vertical to horizontal. This ensures that when the scraper 158 returns to its original position, residual feces will not be pushed deep into the feces collection chamber. Then, the electric push rod 1513 pulls the scraper 158 back to its vertical position for easy scraping next time. When the scraper 158 moves to push feces, it is resisted by the limiting plate 159, preventing excessive tilting due to increased resistance after scraping a large amount of feces, thus achieving rapid discharge of feces. When the reciprocating screw 152 moves to its end after removing the screw sleeve 154, the pressure sensor 155 presses against the side plate 151 or the servo motor 153. The PLC controller then controls the servo motor 153 to stop or rotate. When the scraper 158 returns to its original position, the PLC controller also controls the electric push rod 1513 to extend, allowing the scraper 158 to rotate horizontally. When in use, the excrement and urine of the pigs are collected 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 discharged through the interface of the manure discharge valve 140. When the mobile pigsty is moved to a place with poor soil fertility, the manure can be discharged and fermented to provide organic fertilizer for local farmers or fields.

[0026] In this embodiment, the mobile pigsty is used for feeding pigs with vegetable waste. The mobile pigsty is moved to a field with vegetable waste, which is then collected and fed into a feeding structure 11. The feeding structure 11 moves the vegetable waste to a cutting section 12, where it is chopped and fed to the pigs. The step of chopping the vegetable waste and feeding it to the pigs includes: Step 1: While all moving plates 5 are in their initial state, chop the leftover vegetables until the strip space 3 is filled with chopped leftover vegetable scraps 56. The state at this point is as follows: Figure 5 As shown in the middle left figure; Step 2: At the pigs' feeding time, control the winding mechanism corresponding to the first movable plate 51 at the top to move the first movable plate 51 down to the target height. At this time, some leftover vegetable scraps 56 on the side of the first movable plate 51 automatically fall 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 image; Step 3: After feeding in Step 2 is completed, control the winding mechanism corresponding to the first movable plate 51 and the second movable plate 52 to move the first movable plate 51 and the second movable plate 52 down to the target height. At this time, some leftover vegetable scraps 56 on the side of the second movable plate 52 automatically fall into the feed trough 80 to continue feeding the pigs. The state at this time is as follows: Figure 5 As shown in the right figure; As the vegetable scraps 56 fall, the liquid feed dispenser 90 is controlled to operate and, according to the set liquid feed dispensing amount, feeds the liquid feed into the trough 80 together, thereby achieving co-feeding of liquid feed and vegetable scraps. Step 4: After feeding in step 3 is completed, control the winding mechanism corresponding to the first movable plate 51 to the third movable plate 53 to move the first movable plate 51 to the third movable plate 53 down to the target height N. At this time, some leftover vegetable scraps 56 on the side of the third movable plate 53 will automatically fall into the feed trough 80 to continue feeding the pigs. Step 5: After feeding is completed in step 4, control the winding mechanism corresponding to the first movable plate 51 to the fourth movable plate 54 to move the first movable plate 51 to the fourth movable plate 54 down to the target height N. At this time, some leftover vegetable scraps 56 on the side of the fourth movable plate 54 will automatically fall into the feed trough 80 to continue feeding the pigs.

[0027] Example 2, referring to Example 1, differs from Example 1 in that: [The following text appears to be a continuation of the previous sentence, possibly related to a combination of two examples.] Figure 15 As shown, each movable plate 5 has two vertical through holes, and a taut steel rope 9 is threaded through each through hole. The upper end of the steel rope 9 is fixedly connected to the top of the enclosure, and the lower end of the steel rope 9 is connected to the bottom of the enclosure. A rope 6 is located between the two steel ropes 9. The main function of this structure is to stably store / store vegetable scraps in the strip space, facilitating stable and smooth feeding of vegetable scraps and making feeding convenient.

[0028] Due to the adoption of a specific structured strip space and a specially arranged feeding structure, the strip space 3 serves as both a feeding mechanism for vegetable waste and a storage space. It solves the problem of large-scale, difficult-to-handle vegetable waste accumulation in the area. During non-vegetable waste recycling periods, it also functions as a passageway. After collecting and chopping the vegetable waste, it can be evenly and temporarily stored in the strip space. Subsequently, it can be evenly and smoothly fed into the troughs, and the feeding amount of vegetable waste can be flexibly and precisely adjusted, with each feeding amount precisely controlled within 100 grams. Excess vegetable waste stored in the strip space can be transferred at designated points and on a regular basis. This invention combines a mobile vehicle with a pigpen, realizing truly mobile farming and feeding. It facilitates the full recycling and utilization of vegetable waste in various vegetable growing areas for feeding. It can easily, conveniently, and stably distribute vegetable waste evenly and quickly in the pigs' feeding area in the mobile pigpen without the need for manual entry into the mobile pigpen, saving time and labor. In the traditional method of manually feeding vegetable scraps, it takes 30 minutes to evenly distribute a fixed amount (100 kg) of vegetable scraps into a feeding trough (10 meters long). However, the method of Example 1 can achieve uniform feeding in less than one minute and does not require manual operation, which is very convenient, time-saving and labor-saving.

7. An application of the mobile pigsty as described in claim 6 in the feeding of pig tail vegetables, characterized in that: The mobile pigsty is moved to a field with vegetable waste, the vegetable waste is collected and fed into the feeding structure (11). The feeding structure (11) moves the vegetable waste to the cutting section (12), cuts it up and feeds it to the pigs.

8. The application according to claim 7, characterized in that, The steps involved in chopping up vegetable scraps and feeding them to pigs include: Step 1: When all the moving plates (5) are in the initial state, the leftover vegetables are chopped until the strip space (3) is filled with chopped leftover vegetable scraps; Step 2: At the time when the pigs are feeding, control the winding mechanism corresponding to the first movable plate (51) at the top to move the first movable plate (51) down to the target height. At this time, some of the leftover vegetable scraps on the side of the first movable plate (51) will automatically fall into the feed trough (80) for the pigs to eat. Step 3: After feeding in step 2 is completed, control the winding mechanism corresponding to the first movable plate (51) and the second movable plate (52) to move the first movable plate (51) and the second movable plate (52) down to the target height 2. At this time, some leftover vegetable scraps on the side of the second movable plate (52) will automatically fall into the feed trough (80) to continue feeding the pigs. While the leftover vegetable scraps fall, the liquid feed dispenser (90) is controlled to operate and, according to the set liquid feed dispensing amount, feeds the liquid feed into the trough (80). Step 4: Control the winding mechanism corresponding to the first movable plate (51) to the Nth movable plate to move the first movable plate (51) to the Nth movable plate down to the target height N. At this time, some leftover vegetable scraps on the side of the Nth movable plate will automatically fall into the feed trough (80) to continue feeding the pigs. Where N=4.
