Description

Technical Field

[0001] The invention belongs to the technical field of poultry breeding, and in particular relates to an underground structure for collecting and harmlessly treating duck breeding excrement. Background Art

[0002] In order to provide users with high-quality pollution-free meat ducks and accelerate the industrialization process of meat ducks, more and more farmers have begun to build meat duck breeding pens and carry out standardized large-scale breeding of meat ducks. During the breeding process of meat ducks, a large amount of feces will be produced. The harmless treatment of feces is an important part of ensuring the hygiene of the breeding environment, preventing the spread of diseases and recycling resources.

[0003] Among the many methods for harmless treatment of duck manure, the dry-wet separation treatment method can not only improve the treatment efficiency of duck manure and reduce waste emissions from farms, but also reduce the spread of pathogens such as parasites in duck manure and improve energy recovery and utilization.

[0004] The existing duck manure harmless treatment device still has the following shortcomings:

[0005] 1. Duck manure has a high water content and high viscosity. When separating dry and wet materials, the manure can easily stick to the filter, causing the filter to be blocked. The liquid in the manure cannot pass through the filter normally, resulting in poor dry and wet separation effect and low efficiency.

[0006] 2. After the dry and wet feces are separated, they tend to clump on the filter. When the solid feces are discharged, the feces clumped on the filter are not easy to fall off, resulting in incomplete feces cleaning. The feces remaining on the filter will accelerate the corrosion of the filter and reduce the service life of the filter.

[0007] 3. After the feces are separated and exported, the feces solids need to be manually transported or additional conveying equipment is added to transport them to underground treatment equipment for centralized treatment. Manual transportation has a low degree of automation and low work efficiency, and the additional transportation equipment makes the feces treatment cost high. Summary of the invention

[0008] The purpose of the present invention is to provide an underground structure for collecting and harmlessly treating duck farming manure in response to the problems raised in the above-mentioned background technology.

[0009] To achieve the above object, the present invention adopts the following technical scheme: an underground structure for collecting and harmlessly treating duck farming excrement, comprising:

[0010] A separation box, wherein the separation box is provided with a feed inlet, a liquid outlet and a solid outlet, and a baffle is fixed inside the separation box;

[0011] A filter screen rotatably connected to a top plate of the separation box;

[0012] A conveying pipe, wherein the inlet of the conveying pipe is connected with the solid outlet, and the outlet of the conveying pipe leads to an underground processing mechanism.

[0013] Furthermore, the filter screen adopts an elastic net, a mounting ring is fixed on the top of the filter screen, the mounting ring is rotatably connected to the top plate of the separation box, a sieve plate is fixed on the bottom of the filter screen, the sieve plate is rotatably connected to the baffle, and the filter screen is driven by a rotating component.

[0014] Furthermore, the rotating assembly includes a motor fixed to the top of the separation box, the output shaft of the motor is connected to a first rotating shaft through a coupling, the first rotating shaft extends into the conveying pipe, a limiting groove is provided on the screen plate, a limiting block is fixed on the first rotating shaft, and when the first rotating shaft rotates, the screen plate is driven to rotate through the limiting block.

[0015] Furthermore, a conveying assembly is provided in the conveying pipe, and the conveying assembly includes a second rotating shaft rotatably connected to the conveying pipe, and a spiral conveying blade is provided on the second rotating shaft. The conveying assembly also includes a transmission component.

[0016] Furthermore, the transmission component includes a sleeve slidably connected to the first rotating shaft, a first bevel gear is fixed on the sleeve, a second bevel gear with the same module as the first bevel gear is fixed on the second rotating shaft, an electric push rod is provided in the conveying pipe, the output end of the electric push rod is rotatably connected to the sleeve, the first bevel gear is meshed with the second bevel gear when the electric push rod is shortened, and the first bevel gear is separated from the second bevel gear when the electric push rod is extended.

[0017] Furthermore, a square groove is provided at the center of the baffle plate, and a folding plate is provided on the first rotating shaft, and the through holes on the sieve plate are completely covered when the folding plate is opened.

[0018] Furthermore, the folding plate includes four support rods rotatably connected to the sliding sleeve and distributed in a circular array, four connecting rods corresponding to the positions of the support rods are rotatably connected to the first rotating shaft, each of the connecting rods is rotatably connected to two triangular plates, and two adjacent triangular plates are rotatably connected, and the folding plate is opened when the electric push rod is extended.

[0019] Furthermore, a vibration assembly is provided in the filter, and the vibration assembly includes a conical barrel fixed on the first rotating shaft, a slide groove is opened on the peripheral side wall of the conical barrel, a slider is slidably connected in the slide groove, a movable rod is movably connected to the slider, and one end of the movable rod away from the slider is movably connected to the filter, the slider is provided with a slide rod, the conical barrel is provided with a circular groove cooperating with the slide rod, and a spring is sleeved on the slide rod.

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] 1. The present invention is provided with a vibration component and an elastic filter screen. When separating wet and dry materials, the filter screen is driven by a motor to rotate back and forth. The filter screen is elastically deformed outward under the action of centrifugal force. At the same time, the slider slides downward along the slide groove under the action of centrifugal force and compresses the spring, so that the movable rod pulls the filter screen inward, and the filter screen is deformed into a "3" shape when rotating. When the motor is switched between forward and reverse rotations, the filter screen stops rotating and returns to its original state. The shape of the filter screen is constantly changing, and feces is not easy to stick to the filter screen. The dry and wet separation effect is good and the efficiency is high.

[0022] 2. The present invention is provided with an electric push rod. When the dry-wet separation is working, the electric push rod is in an extended state. At this time, the folding plate is opened to block the through holes of the sieve plate to prevent duck feces from falling directly into the conveying pipe. The first bevel gear and the second bevel gear are separated, and the conveying pipe does not work. When the feces are exported after the dry-wet separation, the electric push rod is shortened to make the first bevel gear and the second bevel gear mesh. When the first rotating shaft rotates, the second rotating shaft drives the spiral conveying blade to rotate synchronously. At this time, the folding plate is in a folded state, and the feces falls from the through holes of the sieve plate into the conveying pipe and is sent to the underground processing mechanism by the spiral conveying blade. The second rotating shaft only rotates when conveying feces, saving resources.

[0023] 3. The present invention sets a vibration component. During the process of exporting fixed feces, when the motor switches forward and reverse, the slider quickly returns to its initial position under the action of the spring, which drives the filter to vibrate, so that the feces agglomerated on the filter falls off the filter, and the feces on the filter are cleaned more thoroughly, thereby increasing the service life of the filter.

[0024] 4. The present invention provides a first bevel gear and a second bevel gear, and the meshing action of the first bevel gear and the second bevel gear drives the spiral conveying blade to work, without the need for additional conveying devices, thus having high working efficiency and low equipment cost.

[0039] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0040] like Figure 1-Figure 9 As shown, an underground structure for collecting and harmlessly treating duck feces comprises a separation box 1, a filter screen 2 and a conveying pipe 3. The separation box 1 is provided with a feed inlet 11, a liquid outlet 12 and a solid outlet 13. A baffle 14 is fixed inside the separation box 1. The filter screen 2 is rotatably connected to the top plate of the separation box 1. The inlet of the conveying pipe 3 is connected to the solid outlet 13, and the outlet of the conveying pipe 3 leads to an underground treatment mechanism.

[0041] During specific operation, duck manure is poured into the separation box 1 from the feed port 11, the duck manure is separated into dry and wet parts in the filter screen 2, the manure liquid is discharged from the liquid outlet 12 to the liquid treatment mechanism, and the manure solid falls into the conveying pipe 3 and is discharged to the solid treatment mechanism.

[0042] The filter screen 2 adopts an elastic net, a mounting ring 21 is fixed on the top of the filter screen 2, the mounting ring 21 is rotatably connected to the top plate of the separation box 1, a sieve plate 22 is fixed on the bottom of the filter screen 2, the sieve plate 22 is rotatably connected to the baffle 14, the filter screen 2 is driven by a rotating assembly, the rotating assembly includes a motor 23 fixed on the top of the separation box 1, the output shaft of the motor 23 is connected to a first rotating shaft 24 through a coupling, the first rotating shaft 24 extends into the conveying pipe 3, a limiting groove 221 is provided on the sieve plate 22, a limiting block 241 is fixed on the first rotating shaft 24, and when the first rotating shaft 24 rotates, the sieve plate 22 is driven to rotate through the limiting block 241;

[0043] During dry-wet separation, the motor 23 drives the first rotating shaft 24 and the filter screen 2 to rotate, and the duck feces rotate synchronously in the filter screen 2 and move toward the filter screen 2 under the action of centrifugal force. The feces solids are blocked in the filter screen 2, and the feces liquid is thrown out from the mesh of the filter screen 2 and hits the side wall of the separation box 1, and then slides down from the side wall of the separation box 1 and is finally discharged from the liquid outlet 12.

[0044] A conveying assembly is provided in the conveying pipe 3, and the conveying assembly includes a second rotating shaft 31 rotatably connected to the conveying pipe 3, and a spiral conveying blade 32 is provided on the second rotating shaft 31. The conveying assembly also includes a transmission component, and the transmission component includes a sleeve 33 slidably connected to the first rotating shaft 24, and a guide block is provided on the sleeve 33. A guide groove is provided on the first rotating shaft 24, and the guide block is slidably connected in the guide groove. A first bevel gear 331 is fixed on the sleeve 33, and a second bevel gear 311 with the same modulus as the first bevel gear 331 is fixed on the second rotating shaft 31. An electric push rod 34 is provided in the conveying pipe 3, and an output end of the electric push rod 34 is rotatably connected to the sleeve 33. When the electric push rod 34 is shortened, the first bevel gear 331 is meshed with the second bevel gear 311, and when the electric push rod 34 is extended, the first bevel gear 331 is separated from the second bevel gear 311;

[0045] During dry-wet separation, the electric push rod 34 is in an extended state, at which time the first bevel gear 331 and the second bevel gear 311 are separated, and the conveying pipe 3 does not work. After the dry-wet separation is completed, the feces falls into the conveying pipe 3 from the solid outlet 13, and the electric push rod 34 automatically shortens to drive the sliding sleeve 33 and the first bevel gear 331 to move downward, and the first bevel gear 331 and the second bevel gear 311 are meshed. When the first rotating shaft 24 rotates, it drives the second rotating shaft 31 and the spiral conveying blade 32 to rotate synchronously to transport the feces.

[0046] A square groove is provided in the center of the baffle 14, and a folding plate 4 is provided on the first rotating shaft 24. When the folding plate 4 is opened, the through hole on the sieve plate 22 is completely covered. The folding plate 4 includes four support rods 41 rotatably connected to the sliding sleeve 33 and distributed in a circumferential array. Four connecting rods 42 corresponding to the positions of the support rods 41 are rotatably connected to the first rotating shaft 24, and two triangular plates 43 are rotatably connected to each connecting rod 42. Two adjacent triangular plates 43 are rotatably connected. When the electric push rod 34 is extended, the folding plate 4 is opened;

[0047] During dry-wet separation, the electric push rod 34 is in an extended state, and the folding plate 4 is stretched to block the through holes on the sieve plate 22, so that feces will not fall from the separation box 1 into the conveying pipe 3. After the dry-wet separation is completed, the electric push rod 34 is shortened to drive the sliding sleeve 33 to move downward, thereby folding the folding plate 4, and the through holes on the sieve plate 22 are opened, and feces falls from the through holes of the sieve plate 22 into the conveying pipe 3.

[0048] A vibration assembly is provided in the filter 2, and the vibration assembly includes a conical barrel 51 fixed on the first rotating shaft 24, a slide groove 52 is provided on the side wall of the conical barrel 51, a slider 53 is slidably connected in the slide groove 52, a movable rod 54 is movably connected to the slider 53, and one end of the movable rod 54 away from the slider 53 is movably connected to the filter 2, a slide rod 531 is provided on the slider 53, a circular groove matching the slide rod 531 is provided on the conical barrel 51, and a spring 532 is sleeved on the slide rod 531;

[0049] During dry and wet separation, the first rotating shaft 24 rotates to drive the filter 2 and the conical barrel 51 to rotate. The filter 2 is elastically deformed outward under the action of centrifugal force. At the same time, the slider 53 slides downward along the slide groove 52 under the action of centrifugal force and compresses the spring 532. The movable rod 54 pulls the filter 2 inward to deform the filter 2 into a "3" shape. When the motor 23 is switched forward and reverse, the filter 2 stops rotating and returns to its original state. At the same time, under the action of the spring 532, the slider 53 quickly returns to its initial position and drives the filter 2 to vibrate.

[0050] The working principle of the present invention is as follows:

[0051] During operation, the electric push rod 34 is controlled to extend, and the extension of the electric push rod 34 drives the sliding sleeve 33 and the first bevel gear 331 to move upward, so that the first bevel gear 331 and the second bevel gear 311 are separated, and at the same time, the sliding sleeve 33 moves upward to drive the folding plate 4 to open, and the folding plate 4 blocks the through hole on the screen plate 22 to prevent the duck feces from falling directly into the conveying pipe 3, thereby improving the dry-wet separation effect;

[0052] Pour duck feces into the separation box 1 from the feed port 11, turn on the motor 23, the motor 23 drives the first rotating shaft 24 and the filter screen 2 to rotate synchronously, the duck feces rotate synchronously in the filter screen 2 and move toward the filter screen 2 under the action of centrifugal force, the feces solids are blocked by the filter screen 2 on the inner side of the filter screen 2, the feces liquid is thrown out from the mesh of the filter screen 2 and hits the side wall of the separation box 1, then slides down from the side wall of the separation box 1 and is finally discharged from the liquid outlet 12;

[0053] The motor 23 rotates to drive the first rotating shaft 24 and the conical barrel 51 to rotate, so that the slider 53 generates a horizontal centrifugal force. According to the action and decomposition of the force, the horizontal centrifugal force can be decomposed into a force diagonally downward along the side wall of the conical barrel 51 and a force perpendicular to the side wall of the conical barrel 51. It can be seen that the slider 53 slides downward along the slide groove 52 under the action of the centrifugal force and compresses the spring 532. The slider 53 drives the movable rod 54 to pull the filter 2 inward. At the same time, when the filter 2 rotates, it elastically deforms outward under the action of the centrifugal force. Finally, the filter 2 is deformed into a "3" shape under the combined action of the centrifugal force and the pulling of the movable rod 54. When the motor 23 rotates, the shape of the filter 2 is constantly changing, and feces is not easy to stick to the filter 2, and the dry and wet separation effect is good.

[0054] After the dry-wet separation is completed, the electric push rod 34 is controlled to shorten, so that the folding plate 4 is folded to open the through hole on the screen plate 22, and the feces fall into the conveying pipe 3 from the through hole, and then the motor 23 is turned on again to speed up the speed at which the feces solid falls into the conveying pipe 3. When the motor 23 is switched forward and reverse, the filter screen 2 and the slider 53 lose the centrifugal force. Under the action of the spring 532, the slider 53 quickly returns to the initial position and drives the filter screen 2 to vibrate, so that the feces agglomerated on the filter screen 2 is separated from the filter screen 2, and the feces on the filter screen 2 are cleaned more thoroughly, which is conducive to improving the service life of the filter screen 2.

[0055] The electric push rod 34 is shortened to drive the first bevel gear 331 to move downward and mesh with the second bevel gear 311. When the first rotating shaft 24 rotates, it drives the first bevel gear 331 to rotate, thereby driving the second rotating shaft 31 and the spiral conveying blade 32 to rotate under the action of gear meshing, and transporting the feces that fall into the conveying pipe 3 to the underground treatment mechanism. There is no need to add an additional conveying device, the work efficiency is high, and the equipment cost is low.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
