The ends of the first elastic rod 8 and the second elastic rod 9 are respectively fixed with a hinge part which is convenient for the vertical hinge shaft to hinge.
The specific working process of the invention is as follows: the initial state of this device is that locating pin 18 inserts the locating hole and spacing into the horizontality with U-shaped pole 4, loosen the pawl simultaneously and make and not stretched by rope 6 at first elastic rod 8, electric telescopic handle 3 is in the contraction state, U-shaped pole 4 is in the lowest extreme position, the axis height of first elastic rod 8 is less than the centre of sphere height of placing subaerial volleyball this moment, second elastic rod 9 is in the rear side of first elastic rod 8, and make first elastic rod 8 and second elastic rod 9 be in same level under stopper 12's effect this moment, the material of first elastic rod 8 can be the vaulting pole that vaulting pole jump motion used, this material is the glass fiber material.
When the device is used, the second elastic rod 9 firstly rotates to a position right above the first elastic rod 8 around the supporting part 10, the connecting rod 11 and the horizontal pin shaft 16 on the connecting rod, at the moment, the first elastic rod 8 is tightened through the crank 20, the ratchet wheel 19 and the pawl structure enable the winding wheel 5 to have a self-locking function, the middle position of the first elastic rod 8 is bent towards the front side in the tightening process of the rope 6 and gradually becomes an arc shape, because the first elastic rod 8 is connected with the second elastic rod 9 through the hinge device, when the first elastic rod 8 is pulled and bent by the rope 6, the second elastic rod 9 is also driven to be elastically deformed, at the moment, the second elastic rod 9 is above the first elastic rod 8 and forms an arc shape which is bent towards the front, in the process, the vertical hinge shaft on the connecting rod 11 provides a rotation pair, the superposition of the two elastic rods enables the height of the second elastic rod 9 to be higher than the center height of a volleyball, at the moment, a worker steps on the board of the sliding plate 13 with one foot and drives the sliding plate 13 with the other foot touching the ground, and meanwhile, the U-shaped frame 1 can be changed in direction by holding the push handle 15 by hand, so that the ground volleyball is collected while the device is driven.
When enough volleyballs are collected by the arc-shaped structure formed by the first elastic rod 8 and the second elastic rod 9, the second elastic rod 9 is manually turned to be parallel to the first elastic rod 8, the first elastic rod 8 and the second elastic rod 9 form a similar annular structure, the collected volleyballs are in the similar annular structure, the pawl is opened and the crank 20 is reversely rotated at the moment, so that the rope 6 is gradually loosened, the two elastic rods tend to be straight under the reset action of the first elastic rod 8 and the second elastic rod 9, the volleyballs in the similar annular structure are pushed to be a straight line, the volleyballs in the similar annular structure are pushed to be at the interval between the first elastic rod 8 and the second elastic rod 9 and are supported, the electric push rod is opened at the moment so that the electric push rod drives the U-shaped rod 4 to move upwards, and after the volleyballs move upwards, the locating pin 18 is pulled out and the pin shaft 16 is rotated in the locating sleeve 17, and the first elastic rod 8 and the second elastic rod 9 which are parallel to each other are inclined, volleyballs roll into the ball frame of the pitching machine along the inclined first elastic rod 8 and the second elastic rod 9, in order to prevent the hinge device from blocking the volleyballs, the inclined guide rod can be arranged on the ball frame, the volleyballs can be assisted to drop when the inclined ends of the first elastic rod 8 and the second elastic rod 9 are placed on the guide rod, or the volleyballs are manually assisted to pass through the hinge device, the first elastic rod 8 and the second elastic rod 9 are reset to the horizontal level after the completion and the electric telescopic rod 3 is retracted and reset.
Compared with the traditional equipment, the device has the following advantages:
1. this device is when collecting the volleyball, and the top of first elastic rod 8 is arranged in to second elastic rod 9, and two elastic rods at this moment form a fence column structure, and when promoting volleyball rapid motion, the volleyball can not cross two breaks away from the constraint of elastic rod, and two elastic rods are crooked into the arc at the ball picking-up in-process simultaneously, and the curved structure can effectively prevent breaking away from of volleyball when collecting the ball this moment for whole device is more reasonable when picking up the ball.
2. This device is picked up ball back and is changeed second elastic rod 9 and make second elastic rod 9 and second elastic rod 9 constitute a class ring form, and the volleyball is tied in annular structure this moment, along with the relaxation of rope 6 under the reset action of elastic rod, irregularly arranged volleyball is put in order into a horizontality and is supported by two elastic rods for whole process lifts up the volleyball and arranges in order convenient subsequent input.
3. The volleyball after accomplishing the arrangement is raised by electric telescopic handle 3 to break away from the rotation that the hand can realize U-shaped pole 4 at locating pin 18, finally realize the slope of two elastic rods, the volleyball of elastic rod slope on two elastic rods is under the effect of dead weight, and accomplishes the volleyball and move automatically to the ball frame of service robot under the guide effect of elastic rod, makes whole process intelligence high efficiency more.
The ball picking device is novel in concept, ingenious in structure and high in practicability, and effectively solves the problems that the existing ball picking device is low in ball picking efficiency and inconvenient to put picked balls into corresponding ball serving devices.
