Description

Technical Field

[0001] The present invention relates to the technical field of grid carriages, and in particular to a grid semi-trailer carriage with a cleaning function. Background Art

[0002] The carriage of a warehouse semi-trailer is a trailer specially used for transporting goods. It is characterized by a fence-like fence around the carriage. The design of the warehouse semi-trailer carriage has both open and closed characteristics. It is usually used to protect the transported goods from the external environment during transportation. The fence can be made of materials such as steel pipes, steel bars or wire mesh. It is usually not completely enclosed to ensure ventilation and visibility. It is usually used to transport live animals such as poultry.

[0003] Although the existing cage semi-trailer compartments can transport poultry and the like very well, the following problems still exist: during the transportation of poultry, the poultry's excrement falls directly to the bottom of the compartment, and the accumulation of excrement requires frequent cleaning, which increases the workload of vehicle maintenance. At the same time, these excrement remain in the compartment for a long time. These excrement may contain pathogens, parasite eggs or viruses. If they are not cleaned in time, they may cause cross-infection and hygiene problems. Especially during centralized transportation, excrement can easily contaminate the environment between poultry and increase the risk of poultry getting sick. Therefore, it is necessary to design a cage semi-trailer compartment that can isolate and collect the excrement (urine and feces) produced by the poultry during transportation, so as to facilitate subsequent cleaning work while effectively preventing the excrement from direct contact with the poultry in the compartment, causing cross-infection and hygiene problems. Summary of the Invention

[0004] In view of the problem that the excrement generated by the existing fence semi-trailer compartment when transporting poultry is difficult to clean and the pathogens in the excrement may cause cross infection among the poultry, a fence semi-trailer compartment with a cleaning function is proposed.

[0005] The present application provides a semi-trailer compartment with a cleaning function, the purpose of which is to: by setting layered components, allow the excrement generated during the transportation of poultry to fall into the bottom box under the action of gravity, and the excrement is vibrated and screened by the vibration of the vehicle during transportation, so that feces and urine can be collected separately.

The sieve plate is located in the bottom box, and the guide plate is located directly below the sieve plate. The two ends of the sieve plate are respectively connected to the corresponding spring telescopic rods through the corresponding connecting holes. Baffle plates are fixedly installed on both sides of the sieve plate, and the two baffle plates are both located on one side of the corresponding connecting hole.

[0008] Furthermore, a counterweight block for increasing the overall mass is fixedly installed at the lower end of the sieve plate, and the counterweight block is made of lead material.

A conduit is fixedly connected between the water outlet pipe and the water collecting ring, a water inlet assembly is installed between the two sealing plates, and a transformer assembly is installed inside the transformer box.

[0010] Furthermore, the water inlet assembly includes a connecting plate arranged between the two sealing plates, a water distribution box arranged on the connecting plate, and a water distribution plate arranged at the lower end of the connecting plate.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] Example 1, with reference to Figures 1-4 , which is a first embodiment of the present invention, provides a compartment semi-trailer with a cleaning function, comprising a mounting plate 1, and a transport unit mounted on the mounting plate 1, wherein the transport unit comprises a layered component mounted on the mounting plate 1 and a cleaning component; The layered components include a bottom box 2 fixedly mounted on a mounting plate 1, a support plate 3 fixedly mounted on the upper end of the bottom box 2, a plurality of guardrails 4 fixedly mounted on both sides of the support plate 3, two sealing plates 5 fixedly mounted on both sides of the upper end of the mounting plate 1, a plurality of partition plates 6 fixedly mounted between the corresponding two guardrails 4, a plurality of through slots 7 are opened on the support plate 3, and a sub-screening assembly is installed inside the bottom box 2; The two sealing plates 5 are respectively located on both sides of the support plate 3 , the multiple guardrails 4 are located between the two sealing plates 5 , the multiple partition plates 6 are equidistantly installed between the corresponding two guardrails 4 , and the multiple guardrails 4 are all made of aluminum alloy.

[0021] Reference Figure 2 and Figure 6The sub-screening assembly includes a protective plate 8 fixedly mounted on the side walls of the two sealing plates 5, a support plate 9 fixedly mounted on the side walls of the sealing plates 5, two spring-loaded telescopic rods 10 fixedly mounted at the lower end of the support plate 9, and communication holes 11 defined on either side of the sealing plates 5. A sieve plate 12 fixedly mounted at the lower ends of the corresponding spring-loaded telescopic rods 10, and a drain plate 13 fixedly mounted at the lower end of the bottom box 2. The sieve plate 12 is located within the bottom box 2, directly below the drain plate 13. The two ends of the sieve plate 12 are connected to the corresponding spring-loaded telescopic rods 10 through the corresponding communication holes 11. A material retaining plate 34 is fixedly mounted on either side of the sieve plate 12, each located on one side of the corresponding communication hole 11. A counterweight 14 made of lead is fixedly mounted at the lower end of the sieve plate 12 to increase the overall mass. The surface of the drain plate 13 is configured as an inclined surface. A liquid discharge pipe (not shown) is fixedly mounted on the side wall of the bottom box 2, located at the lowest end of the inclined surface of the drain plate 13.

[0022] Specifically, the layered components are used to separate and collect poultry excrement. The support plate 3 is used to support the poultry. Through slots 7 are provided on the support plate 3 so that when the poultry produces excrement, most of it falls into the bottom box 2 under the action of gravity. The excrement is collected in the bottom box 2, preventing excrement from accumulating on the support plate 3 for a long time, causing contact between the poultry and the excrement and possible cross-infection of viruses. This also facilitates subsequent cleaning of the carriage by staff. The partition plate 6 is used to separate the interior of the carriage, ensuring safety during the poultry transportation process. The layered structure also facilitates staff management of the poultry. The screening component is used to pass through the vibration generated by the vehicle during transportation, and to screen and collect the generated excrement through the sieve plate 12, collect urine in the drainage plate 13, and collect feces on the sieve plate 12, and collect urine and excrement separately. It can not only reduce the odor generated by the excrement, but also enable the staff to use different methods to clean according to the different components of urine and feces during the cleaning process, thereby effectively improving the cleaning efficiency. A counterweight block 14 is fixedly installed under the sieve plate 12. The counterweight block 14 has a large mass and is used to increase the overall mass of the sieve plate 12, thereby increasing the inertia of the sieve plate 12. When the vehicle vibrates up and down during transportation (such as speed bumps), the sieve plate 12 will move up and down under the action of inertia, thereby achieving the effect of vibration, and vibrating and screening the excrement above, and collecting urine and feces separately.

[0023] During use, when the carriage transports poultry, the poultry is located on the support plate 3 and is separated by the partition plate 6. When the poultry produces excrement, most of the excrement will fall through the through groove 7 to the sieve plate 12 in the bottom box 2 under the action of gravity. When the vehicle vibrates during transportation, the sieve plate 12 will vibrate greatly due to inertia during the vibration process. The sieve plate 12 vibrates the excrement during the vibration process, and the feces and urine are collected separately. The urine flows into the drainage plate 13 under the action of gravity, and the feces remains on the sieve plate 12. During the cleaning process, the staff can disassemble the sieve plate 12 and clean it, and release the urine from the drainage plate 13 through the drain pipe.

[0024] Example 2, reference Figure 4-Figure 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the cleaning component includes a water collecting ring 15 fixedly installed at the lower end of the side wall of the partition plate 6, a plurality of water nozzles 16 fixedly installed on the inner circle of the water collecting ring 15, a transformer box 17 fixedly installed on the partition plate 6, a water inlet pipe 18 fixedly installed at the upper end of the transformer box 17, a water outlet pipe 19 fixedly installed at the lower end of the transformer box 17, a conduit 20 fixedly connected between the water outlet pipe 19 and the water collecting ring 15, a water inlet assembly is installed between the two sealing plates 5, and a transformer assembly is installed inside the transformer box 17.

[0025] The transformer assembly includes a sealed plate 25 provided at the upper end of the transformer box 17, a one-way pipe 26 fixedly mounted on the sealed plate 25, a one-way valve member fixedly mounted in the one-way pipe 26, a piston plate 27 slidably mounted on the inner wall of the transformer box 17, a pull rod 28 fixedly mounted on the lower end of the piston plate 27, and multiple one-way pipes 29 fixedly mounted on the piston plate 27. One-way valve members are also provided in the one-way pipes 29, and the flow directions of the two one-way valve members are opposite. The lower ends of the multiple pull rods 28 are fixedly connected to the upper surface of the sieve plate 12. Specifically, the function of the transformer assembly is to drive the relative vibration of the sieve plate 12 during vehicle travel, so that the sieve plate 12 drives the pull rod 28 to move synchronously. The pull rod 28 causes the piston plate 27 to reciprocate in the transformer box 17. The reciprocating motion of the piston plate 27 continuously changes the pressure in the transformer box 17, so that the stationary water source in the transformer box 17 is pressed into the water outlet pipe 19 by the piston plate 27. Through the change in pressure, the water source in the water outlet pipe 19 is pressed into the water collecting ring 15 through the conduit 20, and the water is directly applied to the surface of the support plate 3 through the water nozzle 16 to clean the excrement on the surface of the support plate 3. Under the action of the water flow, the excrement flows into the bottom box 2 through the through groove 7 for subsequent separate treatment. At the same time, the sprayed water can effectively reduce the odor generated by the excrement, ensuring the cleanliness of the air inside the car during transportation.

[0026] Reference Figure 9 and Figure 10The one-way valve component includes a mounting ring 30 and a sealing ring 31 respectively arranged on the inner walls of the one-way tube 1 26 and the one-way tube 2 29, a plurality of sealing springs 32 arranged on the side wall of the mounting ring 30, and a sealing baffle 33 arranged at the lower ends of the corresponding plurality of sealing springs 32. The end face shape of the sealing baffle 33 is larger than the inner ring end face shape of the sealing ring 31, and the sealing ring 31 is located between the mounting ring 30 and the sealing baffle 33.

[0027] Specifically, the one-way valve is used to realize the water supply and discharge of the transformer assembly during the voltage transformation process. When the pull rod 28 moves downward, the piston plate 27 moves downward and sucks the water flow in the water inlet pipe 18 into the transformer box 17. At the same time, the water source in the lower part of the piston plate 27 in the transformer box 17 is pressed into the water outlet pipe 19, and continues to be pressed into the water outlet 16 in the water collecting ring 15 to clean the surface of the support plate 3. When the piston plate 27 moves upward, the piston plate 27 presses the water source in the upper part of the piston plate 27 into the lower area of ​​the piston plate 27 through the one-way valve, providing water source preparation for subsequent cleaning work.

[0028] During use, when the sieve plate 12 vibrates up and down during transportation by a vehicle, the sieve plate 12 drives the pull rod 28 and the piston plate 27 at its upper end to move downward during the downward vibration process. When the piston plate 27 moves downward, the water source in the water inlet pipe 18 is sucked into the interior of the transformer box 17 and the area above the piston plate 27. At the same time, the water source below the piston plate 27 is pressed into the water outlet pipe 19 during the downward movement of the piston plate 27 and sprayed out through the water nozzle 16 in the water collecting ring 15 to flush the excrement on the support plate 3. When the piston plate 27 moves upward, the piston plate 27 presses the water source above the piston plate 27 into the bottom of the piston plate 27, so that when the piston plate 27 moves downward again, the new water source below is pressed into the support plate 3 to clean the excrement on its surface.

[0029] The remaining structures are the same as those of Example 1.

[0030] Example 3, reference Figure 1-Figure 2 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the water inlet assembly includes a connecting plate 21 fixedly installed between the two sealing plates 5, a water distribution box 22 fixedly installed on the connecting plate 21, and a water distribution plate 23 fixedly installed at the lower end of the connecting plate 21. The upper end of the water distribution plate 23 is fixedly connected to the lower end of the water distribution box 22, and a plurality of water diversion pipes 24 are fixedly installed at the lower end of the water distribution plate 23. The lower ends of the plurality of water diversion pipes 24 are fixedly connected to the water inlet pipe 18.

[0031] Specifically, the water distribution tank 22 is used to provide water to the transformer box 17. When the internal pressure of the transformer box 17 changes, the transformer box 17 draws water from the water distribution tank 22 into the transformer box 17 through the water inlet pipe 18 and the water diversion pipe 24. At the same time, a heating pipe (not shown) is installed inside the water distribution plate 23 to heat the water in the water distribution tank 22, so that it can be used normally even in cold winter weather.

[0032] The remaining structures are the same as those of Example 2.

[0033] Based on Examples 1-3, the working principle of the present invention is as follows: when the carriage transports poultry, the poultry is located on the support plate 3 and is separated by the partition plate 6. When the poultry produces excrement, most of the excrement will fall through the through groove 7 to the sieve plate 12 in the bottom box 2 under the action of gravity. When the vehicle vibrates during transportation, the sieve plate 12 will vibrate greatly due to inertia during the vibration process. The sieve plate 12 vibrates the excrement during the vibration process, and the feces and urine are collected separately. The urine flows into the drainage plate 13 under the action of gravity, and the feces remains on the sieve plate 12. During the cleaning process, the staff can disassemble the sieve plate 12 and clean it, and release the urine from the drainage plate 13 through the drain pipe.

[0034] When the sieve plate 12 vibrates up and down during transportation by the vehicle, the sieve plate 12 drives the pull rod 28 and the piston plate 27 at its upper end to move downward during the downward vibration process. When the piston plate 27 moves downward, the water source in the water inlet pipe 18 is sucked into the interior of the transformer box 17 and the area above the piston plate 27. At the same time, the water source below the piston plate 27 is pressed into the water outlet pipe 19 during the downward movement of the piston plate 27 and sprayed out through the water nozzle 16 in the water collecting ring 15 to flush the excrement on the support plate 3. When the piston plate 27 moves upward, the piston plate 27 presses the water source above the piston plate 27 into the bottom of the piston plate 27, so that when the piston plate 27 moves downward again, the new water source below is pressed into the support plate 3 to clean the excrement on its surface.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
