Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 5, a ball picking device comprises a chassis 1, the chassis 1 is provided with two front wheels 12 and a rear wheel 19 which rotate independently, the chassis 1 is further provided with a ball picking cage 10 which can rotate, the rotation axis of the ball picking cage 10 is parallel to the rotation axis of the front wheel 12, the ball picking cage 10 comprises a pair of turntables 2 and elastic rope bodies 3 which are distributed along the circumferential direction and are connected with the two turntables 2, and the elastic rope bodies 3 can deform under the pressure of a ball 21; the front wheel 12 drives the ball picking cage 10 to rotate in the same rotation direction through a transmission mechanism.

When the equipment works, a user pushes the equipment to move towards the direction of a target ball body 21, when a ball picking cage 10 contacts the ball body 21, the ball body 21 generates pressure on the elastic rope body 3 to enable the elastic rope body 3 to deform, when the deformation of the elastic rope body 3 reaches the requirement of entering the ball body 21, the ball body 21 enters the cage, meanwhile, the elastic rope body 3 resets under the elastic potential energy and completely brings the ball body 21 into the cage, and because the mass of the ball body 21 is very light, the ball body 21 entering the cage cannot generate larger pressure on the elastic rope body 3 to enable the elastic rope body 3 to deform greatly. In this way, when the ball picking cage 10 runs over each ball 21, the ball picking cage can be received therein to realize the function of automatic ball picking. Because the front wheel 12 and the ball picking cage 10 rotate in the same direction, the ball 21 can be accommodated in the ball picking cage 10 without contacting the ground. In order to ensure the reliability of ball picking, when the elastic body 3 of the ball picking cage 10 rotates to the lowest point, the position is not higher than the position of the spherical center of the ball body 21. When the ball body 21 in the cage needs to be taken out, the ball body 21 can be discharged only by pulling the elastic rope body 3 to one side by hand, and the operation is very convenient.

Further, the ball picking cage 10 is detachably arranged on a central rotating shaft 8, and the central rotating shaft 8 is rotatably arranged on the chassis 1. In this way, the ball picking cage 10 can be more conveniently taken down, and the space in the cage can be changed by adjusting the distance between the two turntables 2 according to actual needs.

The timeliness of transmission can be ensured through gear transmission, and the same rotating direction of the ball picking cage 10 and the front wheel 12 can be ensured, so that ball picking can be completed better.

Furthermore, two sides of the head of the chassis 1 are respectively provided with a stand column 11, the stand column 11 is provided with a detachable pressing block 7, the stand column 11 and the pressing block 7 are provided with semicircular holes for rotatably connecting the end parts of the central rotating shaft 8, the intermediate shaft 13 and the front wheel 12 are rotatably arranged on the stand column 11, and the central rotating shaft 8, the intermediate shaft 13 and the front wheel 12 are sequentially arranged from top to bottom. Briquetting 7 and stand 11 adopt to dismantle the connection to can take off central pivot 8, thereby be convenient for maintenance work.

Further, a shaft sleeve 4 is arranged at the center of the rotating disc 2, and the shaft sleeve 4 is connected with the central rotating shaft 8 through a connecting piece I5. The shaft sleeve 4 and the central rotating shaft 8 are provided with pin holes, and the connecting piece I5 is inserted into the pin holes to connect the shaft sleeve 4 and the central rotating shaft 8, so that the turntable 2 and the central rotating shaft 8 can be quickly connected, and the installation difficulty is reduced. The connector I5 may be a bolt.

Furthermore, the disc surface of the rotary disc 2 is also provided with ribs 6 distributed along the circumferential direction, and the inner ends of the ribs 6 extend to the shaft sleeve 4. The ribs 6 can improve the strength of the turntable 2, thereby prolonging the service life.

Further, the disc surface of the turntable 2 is provided with a plurality of hollow structures, and the hollow structures are provided with a mesh enclosure 22. The mesh enclosure 22 allows the user to see the inside of the cage from the side and also prevents the balls 21 from leaking out from the side.

Furthermore, the tail part of the chassis 1 is pivotally connected with a handrail frame 15 and an adjustable telescopic rod 23, the handrail frame 15 is provided with a cross rod 16, and the end part of the adjustable telescopic rod 23 is pivotally connected with the cross rod 16. The adjustable telescopic rod 23 comprises a sleeve body 18 and a rod body 17, the sleeve body 18 is pivoted on the chassis 1, the rod body 17 is pivoted on the cross rod 16, the sleeve body 18 and the rod body 17 are provided with pin holes, the number of the pin holes can be multiple, so that the telescopic length can be adjusted, and the rod body 17 is inserted into the sleeve body 18 and is connected with the sleeve body 18 through a connecting piece II 19. The connector II19 may be a latch. The handrail frame 15 can facilitate the user to push the equipment to move, and is convenient to operate.

Furthermore, the rear wheels 19 are universal wheels, so that the equipment can be steered in cooperation with the operation of a user, and the flexibility of the operation is improved.

Further, the distance between the elastic ropes is not larger than 3/4 of the diameter of the picked-up ball 21, the ball 21 can be better accommodated by the arrangement, and the ball 21 is prevented from leaking due to the fact that the distance is increased because the elastic ropes 3 become loose.
