Description

Technical Field

[0001] This utility model relates to the field of pigpen cleaning technology, specifically to a pigpen rinsing device. Background Technology

[0002] In large-scale pig farming, regular cleaning of pig pens is a crucial step in ensuring pig health and reducing the risk of disease. Currently, most pig farms still rely on manual high-pressure water guns to clean each pen. This method is not only labor-intensive and time-consuming, but also requires a large investment of manpower, leading to a continuous increase in labor costs. Furthermore, the cleaning quality is easily affected by factors such as the worker's experience and physical strength, making it difficult to maintain consistency.

[0003] Although some manufacturers have launched track-mounted or mobile automatic flushing equipment in an attempt to replace manual labor, the existing products are still insufficient in terms of flushing coverage and have blind spots in cleaning, resulting in some dirt residue. This often requires manual secondary cleaning, which not only increases the workload but also fails to fundamentally reduce costs and increase efficiency. Utility Model Content

When the first mating seat abuts against the second mating seat and the first extrusion member passes through the second groove and the second extrusion member passes through the first groove, the first fastener and the second fastener tightly clamp the first extrusion block and the second extrusion block through the first groove and the second groove.

[0011] As a further embodiment of this utility model: one end of the first fastener has a first narrow end, and one end of the second fastener has a second narrow end. The first narrow end is used to insert into the second groove, and the second narrow end is used to insert into the first groove.

Afterwards, the water source solenoid valve at the external pipeline or water source can be opened, allowing high-pressure water to be sent into the multi-degree-of-freedom flushing arm through the external pipeline, and then into the rotating nozzle through the internal flow channel of the multi-degree-of-freedom flushing arm. Since the rotating nozzle uses an automatic rotating nozzle, when the high-pressure water enters the automatic rotating nozzle, the automatic rotating nozzle will start to rotate 360° and spray using the torque generated by its own tangential hole, thereby achieving multi-range and multi-angle cleaning, resulting in a higher cleaning area, cleaning zone, and cleaning efficiency. Furthermore, the operator can also use a remote control or PLC to control the pitch, rotation, and extension / retraction movements of the multi-degree-of-freedom flushing arm, so that the rotating nozzle is aimed at the pen floor, partitions, and under the slatted floor, allowing the rotating nozzle to cover the dead corners under the pen floor, partitions, and slatted floor. For example, the multi-degree-of-freedom flushing arm has four degrees of freedom, and the rotating nozzle, using an automatic rotating nozzle, adds another degree of freedom, giving this device five degrees of freedom for flushing.

[0016] The automatic rotating nozzles rely on water pressure to rotate, forming a circumferential water curtain, which first expands the coverage area of ​​a single wash. The multi-degree-of-freedom flushing arms then combine pitching, telescopic, and rotating movements to ensure that the water jet is always directed towards ground gaps, the back of partitions, and under the slatted floorboards. Dead corners are continuously impacted, splashing is controlled, and the flushing coverage is greatly improved. This effectively reduces the need for manual re-washing and fundamentally achieves cost reduction and efficiency improvement. Attached Figure Description

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

[0021] See Figures 1-3 An embodiment of the present invention provides a pigpen flushing device, comprising: a movable base 1, a multi-degree-of-freedom flushing arm 2, a rotating nozzle 3, and a fixing mechanism 4; the movable base 1 is placed on the ground and can be driven by its own walking motor or pulled or pushed by an external power source; the multi-degree-of-freedom flushing arm 2 is mounted on the movable base 1; the rotating nozzle 3 is detachably mounted on the flushing end of the multi-degree-of-freedom flushing arm 2 through the fixing mechanism 4; wherein, the rotating nozzle 3 is an automatic rotating nozzle, the multi-degree-of-freedom flushing arm 2 has a flow channel inside, one end of the flow channel is connected to the rotating nozzle 3, and the other end of the flow channel is used to connect to an external pipeline.

[0022] Specifically, the movable base 1 moves to the outside of the pigpen to be cleaned; then, the end of the internal flow channel of the multi-degree-of-freedom flushing arm 2 away from the rotating nozzle 3 can be connected to the water source through an external pipeline. After that, the water source solenoid valve at the external pipeline or water source can be opened, and then high-pressure water is sent into the multi-degree-of-freedom flushing arm 2 through the external pipeline, and enters the rotating nozzle 3 through the internal flow channel of the multi-degree-of-freedom flushing arm 2. Since the rotating nozzle 3 uses an automatic rotating nozzle, when the high-pressure water enters the automatic rotating nozzle, the automatic rotating nozzle will start to rotate 360° to spray using the torque generated by its own tangential hole, thereby achieving multi-range and multi-angle cleaning, with higher cleaning area, cleaning zone and cleaning efficiency. In addition, the operator can also use the remote control or PLC to call the pitch, rotation and extension movements of the multi-degree-of-freedom flushing arm 2, so that the rotating nozzle is aimed at the ground of the enclosure, the partition and the area under the slatted floor, and the rotating nozzle 3 covers the dead corners of the ground of the enclosure, the partition and the area under the slatted floor. In this embodiment, the multi-degree-of-freedom flushing arm 2 has four degrees of freedom, and the rotating nozzle 3 uses an automatic rotating nozzle to add another degree of freedom, so this device has five degrees of freedom for flushing.

[0023] Furthermore, the automatic rotating nozzles rely on water pressure to rotate, forming a circumferential water curtain, which first expands the coverage area of ​​a single wash. The multi-degree-of-freedom flushing arm 2 then adds pitching, telescopic, and rotating movements, so that the water column is always directed towards the ground gaps, the back of the partition, and the bottom of the slatted panel. Dead corners are continuously impacted, splashing is controlled, and the flushing coverage rate is greatly improved. This effectively reduces the need for manual re-washing and fundamentally achieves cost reduction and efficiency improvement.

[0024] See Figures 1-3 Optionally, the multi-degree-of-freedom rinsing arm 2 includes a rotating column 21, a first rotating motor 22, a first push rod 23, a telescopic arm 24, a second rotating motor 25, and a spray arm 26. During rinsing, the PLC (Programmable Logic Controller) sends start / stop and speed commands sequentially to the drivers of the first rotating motor 22, the first push rod 23, the second push rod 243, and the second rotating motor 25 via the CAN-open (Controller Area Network Bus Protocol) bus. The drivers of the first rotating motor 22, the first push rod 23, the second push rod 243, and the second rotating motor 25 are all connected to the same CAN-open bus. In existing automatic rinsing equipment, PLC control is already mature and will not be elaborated upon in this embodiment. The first rotary motor 22 is mounted on the movable base 1, and the rotating column 21 is mounted on the output side of the first rotary motor 22. The first rotary motor 22 is used to drive the rotating column 21 to rotate. One end of the rotating column 21 is movably connected to the telescopic arm 24. The first push rod 23 is mounted on the rotating column 21, and the output end of the first push rod 23 is connected to the telescopic arm 24. The movable end of the telescopic arm 24 is provided with a second rotary motor 25, and the output side of the second rotary motor 25 is equipped with a spray arm 26. The rotating nozzle 3 is mounted on the spray arm 26.

[0025] In this embodiment, the first rotary motor 22 is used to drive the rotating column 21 to rotate 360 ​​degrees, and the telescopic arm 24 can extend and retract to achieve "deep and shallow feeding". The first push rod 23 can drive the telescopic arm 24 to pitch on the rotating column 21 to achieve "high and low angle". The second rotary motor 25 can drive the spray arm 26 to rotate 360 ​​degrees around its own axis, further expanding the coverage of the equipment.

[0026] See Figures 1-3 Optionally, the rotating column 21 is vertically mounted on the movable base 1, and the rotation center axis of the spray arm 26 is perpendicular to the telescopic arm 24.

[0027] In this embodiment, by vertically setting the rotating column 21 and the movable base 1, the multi-degree-of-freedom flushing arm 2 can achieve "horizontal sweeping". By setting the rotation center axis of the spray arm 26 perpendicular to the telescopic arm 24, the longitudinal range of the telescopic arm 24 can be further expanded.

[0028] See Figures 2-3 Optionally, the spray arm 26 includes a first connecting pipe 261 and a second connecting pipe 262 perpendicular to the first connecting pipe 261. The first connecting pipe 261 is perpendicular to the telescopic arm 24 and is installed on the output side of the second rotary motor 25. The second connecting pipe 262 is connected to the rotary nozzle 3 through the fixing mechanism 4.

[0029] In this embodiment, the vertical arrangement of the first connecting pipe 261 and the second connecting pipe 262 avoids mechanical interference between the spray arm 26 and the equipment during operation. In actual flushing, pig farm water often contains rust and fine sand. The minimum orifice diameter of the rotating nozzle is usually 0.8–1.2 mm. Once blocked, the jet will become eccentric or stop rotating. Using the fixing mechanism 4 on-site to quickly replace the rotating nozzle 3 can effectively improve work efficiency.

[0030] See Figures 4-6 Optionally, the fixing mechanism 4 includes a first connecting part 41 and a second connecting part 42 respectively connected to opposite sides of the rotary nozzle 3 and the second connecting pipe 262, and the first connecting part 41 and the second connecting part 42 cooperate to assemble and disassemble the rotary nozzle 3.

[0031] In this embodiment, the first connecting part 41 is aligned and axially pushed toward the second connecting part 42, and then the first connecting part 41 is rotated until the fixing mechanism 4 fixes the rotating nozzle 3 onto the second connecting pipe 262. After rinsing, the rotating nozzle 3 can be quickly removed for maintenance or replacement by rotating it in the opposite direction.

[0032] See Figures 4-6Optionally, the first connecting portion 41 includes a first mating seat 411 fixedly connected to the mounting side of the rotary nozzle 3, a first fastener 412 fixedly connected to the first mating seat 411 on the outer side away from the rotary nozzle 3, and a first pressing block 413 fixedly connected to the first mating seat 411 on the outer side away from the rotary nozzle 3; the second connecting portion 42 includes a second mating seat 421 fixedly connected to the outer side of the second connecting pipe 262 away from the first connecting pipe 261, a second fastener 422 fixedly connected to the second mating seat 421 on the side away from the second connecting pipe 262, and a second pressing block 423 fixedly connected to the second mating seat 421 on the side away from the second connecting pipe 262. The first fastener 412 has a first groove 412a on its inner side, and the second fastener 422 has a second groove 422a on its inner side. Both the first groove 412a and the second groove 422a are used for the passage of the first extrusion block 413 and the second extrusion block 423. When the first mating seat 411 abuts against the second mating seat 421 and the first extrusion block passes through the second groove 422a, and the second extrusion block passes through the first groove 412a, the first fastener 412 and the second fastener 422, through the first groove 412a and the second groove 422a, hold the first extrusion block 413 and the second extrusion block 423 together. 3. The second extrusion block 423 tightly clamps the first extrusion block 413 and the second extrusion block 423, both of which are fan-shaped. A portion of the first extrusion block 413 is located in the first groove 412a of the first fastener 412, and a portion of the second extrusion block 423 is located in the second groove 422a of the second fastener 422. When the first connecting part 41 and the second connecting part 42 are in the docking state, one end of the first extrusion member extending out of the first fastener 412 faces the second groove 422a, and one end of the second extrusion member extending out of the second fastener 422 faces the first groove 412a.

[0033] In this embodiment, when installing the rotating nozzle 3, the first mating seat 411 is axially aligned with the second mating seat 421, so that the protruding ends of the first fastener 412, the second fastener 422, and the second pressing block 423 are misaligned. Then, the first mating seat 411 and the second mating seat 421 are brought into contact. The first connecting part 41 and the rotating nozzle 3 as a whole are rotated clockwise, so that the first pressing block 413 is inserted into the second groove 422a, and the second pressing block 423 is inserted into the first groove 412a, until the first pressing block 413 and the second pressing block 423 are tightly fitted with the inner walls of the first groove 412a and the second groove 422a. Furthermore, the first pressing block 413 and the second pressing block 423 are both made of elastic rubber, which further enhances the friction between the inner wall of the groove and the pressing block. In addition, the rotation direction of the automatic rotating nozzle is singular. In this embodiment, the automatic rotating nozzle also rotates clockwise, which does not violate the installation direction of the first mating seat 411.

[0034] See Figures 4-6Optionally, one end of the first fastener 412 has a first narrow end 413a, and one end of the second fastener 422 has a second narrow end 423a. The first narrow end 413a is used to insert into the second groove 422a, and the second narrow end 423a is used to insert into the first groove 412a.

[0035] In this embodiment, the design of the first narrow end 413a and the second narrow end 423a facilitates the insertion of the first extruder into the second groove 422a and the insertion of the second extruder into the first groove 412a.

[0036] See Figures 4-6 Optionally, at least two of the first fastener 412 and the second fastener 422 are provided, and the number of the first pressing block 413 and the second pressing block 423 are the same as the number of the first fastener 412 and the second fastener 422.

[0037] In this embodiment, the increase in the number of the first fastener 412, the second fastener 422, the first pressing block 413, and the second pressing block 423 can enhance the tightness of the installation of the fixing mechanism 4.

[0038] Furthermore, both the first mating seat 411 and the first mating seat 411 are provided with sealing rings 43. When the first mating seat 411 is installed on the first mating seat 411, the two sealing rings 43 abut tightly, enhancing the sealing performance of the spray arm 26. The water pipe is connected to the water inlet end of the spray arm 26.

[0039] See Figures 1-3 Optionally, the telescopic arm 24 includes a mounting arm 241 hinged to the rotating column 21, and a movable arm 242 slidably connected to the inner side of the mounting arm 241. A second push rod 243 is fixedly mounted on the mounting arm 241, and the movable end of the second push rod 243 is hinged to the movable arm 242. The mounting arm 241 is movably connected to the rotating column 21. The movable end of the first push rod 23 is hinged to the mounting arm 241. A mounting frame 251 is provided on the side of the movable arm 242 away from the mounting arm 241. The mounting frame 251 is fixedly mounted on the second rotary motor 25. A support frame 252 is fixedly connected to one side of the mounting frame 251. The spray arm 26 is rotatably connected to the support frame 252. The support frame 252 is used to provide support for the movement of the spray arm 26.

[0040] In this embodiment, the second push rod 243 can drive the movable support arm 242 to move inside the mounting support arm 241, so that the telescopic arm 24 can achieve the telescopic function, and the multi-degree-of-freedom flushing arm 2 has horizontal longitudinal degree of freedom, which can reach the far end of the pig pen.

[0041] It should be added that the rotating column 21, telescopic arm 24 and mounting bracket 251 are hollow inside for wiring. The external water pipe is connected to the water inlet on the first connecting pipe 261, and then enters the rotating nozzle 3 through the second connecting pipe 262, the second mating seat 421 and the second mating seat 421 before being sprayed out.

[0042] See Figures 1-3 Optionally, the movable base 1 is provided with a positioning component 5. The positioning component 5 includes a positioning frame 51 disposed on the movable base 1 and a positioning wheel 52 connected to the positioning frame 51. The positioning component 5 is provided with two sets, and the two positioning wheels 52 extend out of the movable base 1 in the same direction. The line connecting the farthest ends of the two positioning wheels 52 from the movable base 1 is parallel to the movement path of the movable base 1.

[0043] In this embodiment, when the device is in motion, the positioning wheel 52 is attached to the lower outer wall of the pigpen, and the positioning wheel 52 rolls on the surface of the pigpen, resulting in low friction and facilitating the linear movement of the movable base 1.
