Description

Technical Field

[0001] This utility model relates to the field of livestock and poultry breeding equipment, and in particular to a mobile high-pressure cleaning device for piglet breeding. Background Technology

[0002] In piglet rearing, maintaining a clean and hygienic rearing environment is crucial for ensuring healthy growth and preventing disease transmission. Feces, feed residue, and secretions easily accumulate in piglet activity areas (such as feeding troughs, enclosures, floors, and watering devices). If cleaning is not timely or thorough, bacteria and mold can easily proliferate, leading to diarrhea, skin infections, and other diseases in piglets, severely impacting rearing efficiency.

[0003] Currently, cleaning the piglet rearing environment mainly relies on manual operation or traditional simple equipment: Manual cleaning: This requires farmers to manually complete the task using tools such as high-pressure water guns and brushes. It is labor-intensive, inefficient, and difficult to cover complex structures (such as trough gaps and fence corners), easily leaving cleaning dead spots; Traditional fixed cleaning equipment: Although some farms are equipped with fixed high-pressure cleaning devices, they have the problem of poor flexibility—they can only clean fixed areas and cannot adapt to the dynamic needs of the piglet activity area (such as troughs in different locations and moving fences); Existing mobile cleaning equipment: Although some improved equipment has the ability to move, it has problems such as a single cleaning angle and non-adjustable pressure: The robotic arm has insufficient freedom of movement and it is difficult to adjust to narrow areas such as the inside of the piglet trough and the gaps between fences; The cleaning unit is mostly a single high-pressure nozzle or a fixed brush, which cannot adjust the contact angle and cleaning intensity according to the cleaning object (such as troughs of different widths and fences of different materials), resulting in unstable cleaning results.

[0004] In summary, there is an urgent need for a high-pressure cleaning device that is compact, mobile, and adjustable in cleaning angle and intensity, and can adapt to the complex environment of piglet farming, in order to solve the problems of low cleaning efficiency, many dead corners, and poor adaptability in existing technologies.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model discloses a mobile high-pressure cleaning device for piglet breeding, comprising: a movable base for supporting the entire device and providing mobility; a robotic arm mounted on the movable base, with its bottom connected to the movable base, the robotic arm consisting of at least two arms connected by hinges and hydraulic drive to achieve multi-degree-of-freedom movement; a rotary table with its bottom hinged to the end arm of the robotic arm; a cleaning unit mounted on the rotary table and rotating with the rotary table in a horizontal plane; the cleaning unit comprising: a cleaning bracket fixed to the rotary table; a brush roller assembly rotatably connected to the cleaning bracket; an arc-shaped baffle covering the outside of the brush roller assembly; a nozzle assembly fixedly disposed on the side of the arc-shaped baffle, with the nozzles facing the brush roller assembly; and an adjustment mechanism disposed between the cleaning bracket and the arc-shaped baffle for adjusting the wrapping angle between the arc-shaped baffle and the brush roller assembly.

[0008] As a preferred embodiment of this utility model, the movable base includes a control trolley and a fixed arm vertically fixed thereon; the robotic arm includes: a first arm: its bottom is hinged to the end of the fixed arm; a second arm: its front end is hinged to the top of the first arm; a first hydraulic rod: its two ends are respectively hinged to the fixed arm and the first arm to drive their rotation; a second hydraulic rod: its two ends are respectively hinged to the first arm and the second arm to drive relative rotation; the bottom of the rotary table's rotating base is hinged to the end of the second arm.

[0009] As a preferred technical solution of this utility model, the rotary table also includes a mounting boss fixedly disposed on the top of the rotary base and a rotary reducer fixedly disposed on the side of the mounting boss. The output shaft of the rotary reducer drives the rotary base to rotate around its vertical axis; the bottom of the cleaning bracket is fixedly connected to the mounting boss.

[0010] As a preferred technical solution of this utility model, the adjustment mechanism includes: a gear and rack transmission mechanism, one end of which is connected to one end of an arc-shaped baffle, the end of which extends and connects along the arc direction of the arc-shaped baffle; a gear drive motor, fixedly mounted on the cleaning bracket, the output shaft of which drives the gear in the gear and rack transmission mechanism to rotate; wherein, the gear drive motor drives the gear and rack transmission mechanism to make the end of the arc-shaped baffle move in an arc relative to the cleaning bracket, thereby realizing the adjustment of the wrapping angle between the arc-shaped baffle and the brush roller assembly.

[0011] As a preferred technical solution of this utility model, the brush roller assembly includes: a brush mounting shaft, which is rotatably mounted on a cleaning bracket via bearings; a brush body, which is sleeved and fixed outside the brush mounting shaft, and has bristles on its outer surface; a roller drive motor, which is mounted on the cleaning bracket, and whose output shaft drives the brush mounting shaft to rotate via a transmission mechanism; the bristles on the brush body extend toward the arc-shaped baffle.

[0012] As a preferred technical solution of this utility model, the nozzle assembly includes: a nozzle bracket, which is fixedly connected to the side of the arc-shaped baffle; multiple atomizing nozzles, which are fixedly installed on the nozzle bracket and face the working area of ​​the brush roller assembly; and a diverter pipe, which is set next to the nozzle bracket, with one end of the diverter pipe used to connect to an external high-pressure water source pipeline and the other end connected to each atomizing nozzle.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The device is equipped with a movable base, which can dynamically adjust the cleaning starting point according to the location of the piglets' activity area; the robotic arm achieves multiple degrees of freedom of movement such as pitch and extension through the hinge and hydraulic drive of at least two arms. Combined with the 360° horizontal rotation function of the turntable, the cleaning unit can be accurately delivered to areas that are difficult for traditional equipment to reach, such as the inside of the feed trough, fence gaps, and ground corners, which greatly improves the cleaning coverage.

[0015] 2. The adjustment mechanism of the cleaning unit can drive the arc-shaped baffle to move along the arc direction, flexibly adjusting the wrapping angle between the baffle and the brush roller assembly to ensure the fit between the brush and the surface to be cleaned during the cleaning process; at the same time, the brush roller assembly and the nozzle assembly work together - the high-pressure water mist first softens the stubborn stains, and then the high-speed rotating brush physically scrubs them, avoiding the problem of sewage splashing or incomplete cleaning caused by single high-pressure rinsing, and the cleaning effect is more stable;

[0016] 3. The hydraulic drive of the robotic arm, the speed reducer rotation of the rotary table, and the motor control of the adjustment mechanism can all be integrated through the electrical control system. Operators only need to set the target position and cleaning parameters through the control panel to complete the automated cleaning, which greatly reduces the intensity of manual labor and is especially suitable for the batch cleaning needs of large-scale farms.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] In the attached diagram, all identical reference numerals refer to the same components.

[0025] Example 1: Basic mobile high-pressure cleaning device, such as Figure 1-4 As shown, this embodiment provides a basic cleaning device suitable for routine environments in piglet farms (such as pigpen fences and localized stains on the ground). The structure and connection relationship of each component are as follows:

[0026] The movable base 1 is the basic support and movement unit of the device, including a control trolley 11 and a fixed arm 12. The control trolley 11 adopts a wheeled walking mechanism (such as a four-wheel drive trolley), the frame is a metal frame structure, the bottom is equipped with drive wheels and guide wheels, and the top is vertically fixed with the fixed arm 12; the fixed arm 12 is a cylindrical or square tube structure, and its end (top) is reserved with a hinge interface.

[0027] Please see Figure 2The robotic arm 2 is hinged to the end of the fixed arm 12 of the movable base 1, and is used to adjust the spatial position of the cleaning unit 3. The robotic arm 2 includes a first arm 21, a second arm 22, a first hydraulic rod 24, and a second hydraulic rod 25: the first arm 21 is a long, plate-like structure, with its bottom hinged to the hinge interface at the end of the fixed arm 12 via a pin, allowing it to swing up and down around this hinge point; the second arm 22 is a plate-like structure shorter than the first arm 21, with its head hinged to the top of the first arm 21 via a pin, allowing it to rotate horizontally relative to the first arm 21 around this hinge point; the first hydraulic rod 24 is a double-acting hydraulic cylinder, its cylinder body connected by a pin... The shaft is hinged to the middle of the fixed arm 12, and the piston rod is hinged to the middle of the first arm 21 by a pin. Driven by hydraulic oil, the first arm 21 can swing up and down (pitch motion) around the hinge point between it and the fixed arm 12. The second hydraulic rod 25 is a double-acting hydraulic cylinder. Its cylinder body is hinged to the upper middle part of the first arm 21 by a pin, and the piston rod is hinged to the head end of the second arm 22 by a pin. Driven by hydraulic oil, the second arm 22 can extend, retract or rotate horizontally around the hinge point between it and the first arm 21.

[0028] Please see Figure 4 The rotary table 23 is installed at the far end of the robotic arm 2 (i.e., the end of the second arm 22) to realize the horizontal rotation of the cleaning unit 3. The rotary table 23 includes a rotary base 231, a mounting boss 232, and a rotary reducer 233: the rotary base 231 is a disc-shaped structure, and its bottom is hinged to the end of the second arm 22 of the robotic arm 2 through a pin, which can realize rotation around the vertical axis; the mounting boss 232 is a cylindrical protrusion structure, which is fixedly welded to the top center of the rotary base 231, and its side has a reserved installation interface;

[0029] The rotary reducer 233 is a gear reduction mechanism, which is fixedly installed on the side of the mounting boss 232. Its input shaft is connected to the output shaft of the hydraulic motor through a coupling, and the output shaft is fixedly connected to the central shaft of the rotary base 231 through a flange. The rotary base 231 can be rotated 360° around the vertical axis by the reducer.

[0030] The cleaning unit 3 is mounted on the mounting boss 232 of the rotary table 23 and is the core module for performing the cleaning action. It includes a cleaning bracket 31, a brush roller assembly 32, an arc-shaped baffle 33, a nozzle assembly 34, and an adjustment mechanism 35.

[0031] The cleaning bracket 31 is a "U" shaped metal bracket, and its bottom is fixedly connected to the top of the mounting boss 232 of the rotary table 23 by bolts. Its vertical section and horizontal section are used to support the brush roller group 32 and the arc-shaped baffle 33, respectively.

[0032] Please see Figure 3The brush roller assembly 32 includes a brush mounting shaft 321, a brush body 322, and a roller drive motor 323. The brush mounting shaft 321 is a horizontally arranged cylindrical shaft, which is rotatably mounted between the two side walls of the vertical section of the cleaning bracket 31 via bearings. The brush body 322 is a cylindrical brush roller, which is sleeved and fixed to the outer periphery of the brush mounting shaft 321. Its outer surface is evenly and densely covered with hard bristles (such as nylon filaments), and the bristles extend towards the arc-shaped baffle 33. The roller drive motor 323 is an AC asynchronous motor, which is fixedly mounted on the outer side wall of the vertical section of the cleaning bracket 31. Its output shaft is connected to one end of the brush mounting shaft 321 through a chain transmission mechanism to drive the brush mounting shaft 321 to rotate.

[0033] The arc-shaped baffle 33 is a semi-circular arc-shaped metal plate. Its curvature matches the outer periphery of the brush roller assembly 32 and covers the outer side of the brush roller assembly 32. Its inner surface has a small gap (about 2-5mm) reserved with the bristles of the brush body 322 to constrain the movement trajectory of the bristles and prevent dirt from splashing.

[0034] An adjustment mechanism 35 is disposed between the cleaning bracket 31 and the arc-shaped baffle 33, and is used to adjust the wrapping angle between the baffle and the brush roller assembly. It includes a rack and pinion transmission mechanism 351 and a gear drive motor 352. The rack of the rack and pinion transmission mechanism 351 is an arc-shaped rack, fixed to the outer side of one end of the arc-shaped baffle 33 along its arc direction. The gear drive motor 352 is a stepper motor, fixedly installed on the outer wall of the horizontal section of the cleaning bracket 31. Its output shaft is connected to a gear shaft via a coupling, and the gear meshes with the arc-shaped rack. By rotating the gear drive motor 352 forward and backward, the rack can be driven to move along the arc direction, thereby causing the end of the arc-shaped baffle 33 to rotate around the cleaning bracket 31, thus adjusting the wrapping angle between the baffle and the brush roller assembly (e.g., 90°-150°).

[0035] The nozzle assembly 34 is fixedly mounted on the side of the arc-shaped baffle 33 and is used to spray high-pressure water into the gap between the brush roller assembly 32 and the baffle. It includes a nozzle bracket 341, atomizing nozzles 342 and a distribution pipe 343. The nozzle bracket 341 is a "T"-shaped metal bracket, and its bottom is fixedly connected to the side of the arc-shaped baffle 33 by bolts. Multiple atomizing nozzles 342 are evenly spaced at the front end of the nozzle bracket 341, with the nozzle direction facing the gap between the brush roller assembly 32 and the arc-shaped baffle 33. The distribution pipe 343 is a metal flexible tube, one end of which is connected to an external high-pressure water source pipeline through a quick-connect coupling, and the other end is connected to the water inlet of each atomizing nozzle 342, which is used to evenly distribute high-pressure water to each nozzle.

[0036] Example 2: Dual-brush roller assembly enhanced cleaning device (focusing on improving cleaning efficiency)

[0037] This embodiment, based on Embodiment 1, optimizes the structure of the brush roller assembly, making it suitable for concentrated cleaning of stubborn stains (such as dried feces and clumps of feed) in piglet farms. The main improvement lies in the number and arrangement of the brush roller assemblies:

[0038] The brush roller group 32 of the cleaning unit 3 includes two sets of parallel and symmetrically arranged brush mounting shafts 321: the brush mounting shafts are horizontally arranged between the vertical sections of the cleaning bracket 31 and are rotatably connected by bearings; each set of brush mounting shafts 321 is fitted with a fixed brush body 322, the bristles of which are slightly longer than those in Embodiment 1 (approximately 15-20mm) and have higher hardness (such as metal wire mixed with nylon filament); the first ends of the two sets of brush mounting shafts 321 are respectively connected to the output shaft of the same roller drive motor 323 (or respectively connected to independent motors) through a chain transmission mechanism to achieve synchronous rotation; the arc of the arc-shaped baffle 33 is similar. It should be adjusted to match the outer periphery of the two sets of brush rollers to form a symmetrical "U"-shaped covering structure; the gear and rack transmission mechanism 351 of the adjustment mechanism 35 is set into two sets, respectively corresponding to the two ends of the arc-shaped baffle 33, and the gear drive motor 352 is installed on both sides of the horizontal section of the cleaning bracket 31 to synchronously drive the racks at both ends to move, ensuring the symmetry when the baffle is adjusted; the number of atomizing nozzles 342 of the nozzle assembly 34 is increased to 8-10 (4-6 in Example 1), which are evenly distributed on both sides of the arc-shaped baffle 33 to cover the working area of ​​the two sets of brush rollers, ensuring that high-pressure water is evenly sprayed into the gap between the two brush rollers.

[0039] Example 3: Large-angle adjustable arc-shaped baffle cleaning device (focusing on cleaning complex curved surfaces)

[0040] This embodiment addresses the cleaning needs of complex curved surfaces such as inclined fences and arc-shaped enclosures in piglet farms by optimizing the adjustment range of the arc-shaped baffle. The main improvement lies in the transmission structure of the adjustment mechanism and the range of motion of the baffle.

[0041] The adjustment mechanism 35 of the cleaning unit 3 adopts a two-stage gear transmission mechanism to expand the baffle adjustment stroke: the output shaft of the gear drive motor 352 of the gear and rack transmission mechanism 351 is connected to the drive gear, the drive gear meshes with the intermediate gear (the diameter is smaller than the drive gear), and the intermediate gear meshes with the arc-shaped rack (fixed to the end of the arc-shaped baffle 33); through two-stage gear reduction, the movement stroke of the rack can be increased, so that the wrapping angle between the arc-shaped baffle 33 and the brush roller group 32 can be adjusted from 90° to 180° (90°-150° in Embodiment 1); the arc-shaped baffle 33 is provided at both ends. A limit switch (not labeled) is electrically connected to the control system of the device. When the baffle is adjusted to the limit angle, a limit signal is triggered to prevent over-adjustment from causing structural damage. The brush body 322 of the brush roller assembly 32 is made of hard bristles (such as stainless steel wire), and the bristle density is increased (about 20-30 bristles / cm), which improves the scraping ability of stubborn stains. The diverter pipe 343 of the nozzle assembly 34 adopts a telescopic corrugated pipe structure. Its length automatically extends and retracts with the angle adjustment of the arc-shaped baffle 33 (driven by a built-in spring or hydraulic cylinder) to ensure that high-pressure water is always sprayed evenly into the gap between the brush roller and the baffle.

[0042] This utility model is a mobile high-pressure cleaning device for piglet breeding. By cleverly combining a mobile platform, a multi-degree-of-freedom robotic arm, a rotary end effector (rotary table), and an adjustable cleaning unit integrating brushing and atomizing spraying functions, it effectively improves the efficiency, uniformity, and adaptability of cleaning the breeding environment, providing reliable hygiene protection for the healthy breeding of piglets, and has significant promotion and application value.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
