Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a grain cleaning brush. Background Art

[0002] After the grain in the grain warehouse is taken away, some grain is still scattered on the ground. The grain warehouse is large, and a sweeper is needed to collect this part of the grain particles. The cleaning brush on the automatic cleaning equipment is crucial to the thoroughness of cleaning the scattered grain particles on the ground.

[0003] Chinese utility model patent CN208055962U discloses a cleaning brush that is easy to install for a road sweeper. A slidable clamping plate is provided on the brush head mounting groove of the brush head mounting seat, and is elastically connected to the brush head mounting seat through a guide rod and a spring. When disassembling, the clamping plate can be squeezed to change the space size of the brush head mounting groove, thereby reducing the friction between the cleaning brush and the brush head mounting seat, making it convenient for operators to disassemble and install the cleaning brush that needs to be replaced.

[0004] However, the grain cleaning brush is different from ordinary road cleaning. When the above-mentioned cleaning brush is cleaning the grain particles on the ground, under the action of centrifugal force, the grain particles are easily thrown out at the cleaning brush, causing some grain particles to bounce to the side away from the cleaning equipment. The cleaning effect needs to be further improved, and dust is serious during the cleaning process. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a grain cleaning brush which can cover and press grain particles and then release them, so that the grain particles gather toward the cleaning device and reduce the grain particles from jumping out.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grain cleaning brush, comprising a mounting arm, a rotating shaft rotatably mounted on the mounting arm and a plurality of cleaning components, wherein the cleaning components are axially evenly distributed at the bottom of the rotating shaft, the cleaning components comprise a mounting frame fixedly connected to the rotating shaft, a bending frame hingedly mounted on the mounting frame and an elastic stretching member, the bending frame being elastically connected to the mounting frame via the elastic stretching member, a driving disk being mounted at the bottom of the mounting arm, a plurality of wavy protrusions being provided on the driving disk, one end of the bending frame extending toward the wavy protrusion on the driving disk, the other end of the bending frame extending downwardly along the radial direction of the rotating shaft, and a brush assembly being mounted at the end of the bending frame away from the rotating shaft.

[0007] Preferably, the brush assembly comprises a brush frame and bristles evenly distributed on the brush frame, and the bristles are provided with a horizontal portion parallel to the ground near the ground.

[0008] Preferably, the bristles include upper bristles, middle bristles and lower bristles which are fixed on the brush frame from top to bottom in sequence, wherein the upper bristles and the lower bristles are both made of carbon fiber material, and the middle bristles are made of nylon material.

[0009] Preferably, the bristles on the multiple cleaning components are arranged in a cone shape.

[0010] Preferably, the brush holder is detachably connected to the bending holder.

[0011] Preferably, a ball is rotatably mounted on one end of the bending frame adjacent to the driving disc.

[0012] Preferably, a blocking cover is installed on the mounting arm, and the blocking cover includes a vertical blocking portion parallel to the central axis of the rotating shaft and a horizontal blocking portion parallel to the ground.

[0013] Preferably, the wavy protrusion is located at a semicircle on one side of the driving disc in the forward direction.

[0014] Compared with the prior art, the utility model provides a grain cleaning brush, which has the following beneficial effects:

[0015] The grain cleaning brush is installed on the cleaning vehicle, and the rotating shaft is driven to rotate by a motor or a driving device on the cleaning vehicle, and the rotating shaft drives each cleaning component to rotate. During the rotation of the cleaning component, one end of the bending frame contacts with the wavy protrusion at the bottom of the driving disk, so that the bending frame rotates around the hinge point with the mounting frame, and the brush component is tilted, so that the grain particles enter the bottom of the brush component. When the bending frame is out of contact with the wavy protrusion, the bending frame is reset under the action of the elastic stretching member, and the grain particles are pressed under the brush component. The grain particles rotate synchronously with the brush component, and then the bending frame contacts with another adjacent wavy protrusion, and the brush component is out of the pressure on the grain particles, so that the grain particles are thrown out and move to one side of the center of the cleaning device. The grain particles can be covered and released, so that the grain particles gather at the cleaning device, reduce the popping out of grain particles, and improve the cleaning effect.

[0016] The bristles are divided into upper bristles, middle bristles and lower bristles, among which the upper bristles and the lower bristles are both made of carbon fiber, and the middle bristles are made of nylon. The upper bristles and the lower bristles made of carbon fiber provide better rigidity, and the middle bristles made of nylon have good toughness. Through the combination of upper bristles, middle bristles and lower bristles, compared with brushes made of steel wire, it can further reduce grain bouncing and dust generation, and reduce dust generated during cleaning. Compared with brushes made of pure nylon, it has better strength, cleans more thoroughly and has a longer service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model discloses a grain cleaning brush, comprising a mounting arm 1, a rotating shaft 2 rotatably mounted on the mounting arm 1 and a plurality of cleaning components, wherein the cleaning components are axially evenly distributed at the bottom of the rotating shaft 2, and a blocking cover 13 is also mounted on the mounting arm 1.

[0025] The cleaning assembly includes a mounting frame 3 fixedly connected to the rotating shaft 2, a bending frame 4 hingedly mounted on the mounting frame 3, and an elastic stretching member 5. The bending frame 4 is elastically connected to the mounting frame 3 through the elastic stretching member 5. A driving disk 6 is installed at the bottom of the mounting arm 1. The driving disk 6 is provided with a plurality of wavy protrusions 7. One end of the bending frame 4 extends toward the wavy protrusions 7 on the driving disk 6, and the other end of the bending frame 4 extends downwardly along the radial direction of the rotating shaft 2. A brush assembly 8 is installed at the end of the bending frame 4 away from the rotating shaft 2. Furthermore, the elastic stretching member 5 is preferably a tension spring, one end of which is hinged to the bending frame 4, and the other end of which is hinged to the upper part of the mounting frame 3. The elastic stretching member 5 can also be an elastic member with an equivalent elastic stretching effect, such as an elastic belt.

[0026] A ball 12 is rotatably mounted on one end of the bending frame 4 adjacent to the driving disk 6; the ball 12 can reduce the friction between the bending frame 4 and the wavy protrusion 7 to improve the rotation smoothness of the cleaning component.

[0027] The wavy protrusion 7 is located at a semicircle on one side of the forward direction of the driving disc 6, and the forward direction of the driving disc 6 is the forward direction of the cleaning vehicle on which the grain cleaning brush is installed. Through the above arrangement, when the driving disc 6 follows the forward movement of the cleaning vehicle, only the cleaning components at the semicircle on one side of the forward direction of the driving disc 6 are driven, while the brush components 8 on the cleaning components at the other semicircle of the driving disc 6 are always in contact with the ground, so as to ensure that the grain particles are thrown to the forward direction of the cleaning vehicle and to one side close to the middle of the cleaning device.

[0028] The blocking cover 13 includes a vertical blocking part parallel to the central axis of the rotating shaft 2 and a horizontal blocking part parallel to the ground. The blocking cover 13 can block the grain particles thrown out by the cleaning component. The horizontal blocking part prevents the grain from bouncing upward, and the vertical blocking part makes the grain particles gather, which is convenient for collecting the grain particles after cleaning. The grain cleaning brush is symmetrically installed on both sides of the cleaning vehicle. The relative relationship between the rotation direction of the brush assembly 8 and the travel direction of the cleaning vehicle can be found in Figure 2 Indicated by the arrow in the figure; in this way, the brush assembly 8 can gather the food particles to the central side of the sweeper.

[0029] See also Figure 4-5 Specifically, the bristles 10 on the multiple cleaning components are enclosed in a cone shape. Through the above arrangement, during the rotation of each cleaning component, the bristles 10 on each cleaning component are enclosed in a closed cone space to further reduce the food particles from bouncing upward during the cleaning process.

[0030] The brush assembly 8 includes a brush frame 9 and bristles 10 evenly distributed on the brush frame 9. The bristles 10 are provided with a horizontal portion 11 parallel to the ground near the ground. Through the above arrangement, the contact area between the brush assembly 8 and the ground can be increased, so that more food particles are pressed on the bottom of the bristles 10 to improve the cleaning effect.

[0031] The brush holder 9 is detachably connected to the bending frame 4 via connectors such as bolts or clips; when the bristles 10 are worn, the bristles 10 can be replaced by removing the brush holder 9, thereby improving the convenience of subsequent maintenance and disassembly of the brush assembly 8.

[0032] The bristles 10 include upper bristles 1001, middle bristles 1002 and lower bristles 1003 fixed on the brush holder 9 from top to bottom, wherein the upper bristles 1001 and lower bristles 1003 are made of carbon fiber, and the middle bristles 1002 are made of nylon. The upper bristles 1001 and lower bristles 1003 made of carbon fiber provide good rigidity, and the middle bristles 1002 made of nylon have good toughness. Through the combination of the upper bristles 1001, the middle bristles 1002 and the lower bristles 1003, compared with the brush made of steel wire, the food bouncing and dust generation can be further reduced, and the dust generated during the cleaning process can be reduced. Compared with the brush made of pure nylon, the strength is better, the cleaning is more thorough, and the service life is longer.

[0033] When in use, the grain cleaning brush is installed on the lower side of the front end of the cleaning vehicle, and the grain cleaning brush is driven to rotate directly by the motor, or the rotating shaft 2 is driven to rotate by the driving device on the cleaning vehicle. The rotating shaft 2 drives each cleaning component to rotate. During the rotation of the cleaning component, one end of the bending frame 4 contacts with the wavy protrusion 7 at the bottom of the driving disk 6, so that the bending frame 4 rotates around the hinge point with the mounting frame 3, and the brush component 8 is tilted, so that the grain particles enter the bottom of the brush component 8. When the bending frame 4 is out of contact with the wavy protrusion 7, the bending frame 4 is reset under the action of the elastic stretching member 5, and the grain particles are pressed under the brush component 8. The grain particles rotate synchronously with the brush component 8, and then the bending frame 4 contacts with another adjacent wavy protrusion 7, and the brush component 8 is out of the pressure on the grain particles, so that the grain particles are thrown out and move to one side of the center of the cleaning device. The blocking cover 13 blocks and limits the grain particles, and the gathered grain particles can be collected.
