Description

Remote Control Automatic Tennis Pickup Machine

technical field

The utility model relates to a remote-controlled automatic tennis ball picking machine, which belongs to the field of sports equipment, in particular to a machine for recovering tennis balls.

Background technique

Currently, tennis is more common in my country, and tennis facilities, such as tennis courts, are provided in many areas. We find that on tennis courts in many places, you can see a lot of tennis balls everywhere, even if there are people playing. However, picking up these tennis balls is the most annoying problem for players. In order to solve these problems we have developed a kind of sports facility-tennis ball pick-up machine. There are also similar products on the market, but those products are mainly manual operation of hand-push ball picking machines, and need to walk along the tennis court, which is labor-intensive, time-consuming, and inefficient; while the more advanced ball picking machines are Fully automatic ball pick-up machines require high technologies such as mechanical arms and image recognition. They can pick up balls automatically without manual operation, but they are inefficient and have a very complicated structure. The cost is quite high and it is not easy to promote.

Utility model content

The purpose of the utility model is to avoid the deficiencies of the prior art, and provide an easy-to-operate, high-efficiency and labor-saving tool suitable for picking up balls used in tennis courts.

The purpose of this utility model is achieved through the following measures. The remote control automatic tennis ball picking machine is composed of a ball picking mechanism, a pull rod type hand push handle, a walking mechanism and a vehicle body. The ball picking mechanism includes a ball picking roller and a brush, Composed of driven pulley, universal front wheel, driving pulley, transmission belt, support frame, front axle, ball picking and collecting baffle, and long axis, the ball picking roller and brush are connected to the driven pulley, and the driven pulley is connected to the transmission belt, the transmission The belt is connected to the driving pulley, and the driving pulley is connected to the universal front wheel. The support frame is fixedly installed with a ball collecting baffle, and the support frame is fixedly installed with an infrared reflection sensor probe. Bracing frame, universal front wheel is installed on the front axle. The body consists of a ball storage box, an infrared receiving tube fixing tube, a frame, a ball guide movable plate, a pulley, an infrared emitting tube, an infrared emitting tube fixing tube, a control circuit board and a battery box, and the infrared receiving tube fixing tube is installed on the frame , the infrared emission tube is installed on the fixed tube of the infrared emission tube, the control circuit board and the battery box are installed on the frame, the ball guide movable plate is installed on the front end of the frame, and the pulley is installed on the ball guide movable plate. The pull-rod push handle consists of a telescopic tube, a handle, and a U-shaped telescopic tube, and the telescopic tube is installed on the handle and the U-shaped telescopic tube. The walking mechanism consists of a suspension spring, a suspension support rod, a motor base plate, a motor base, a driving deceleration motor, a coupling, and a driving rear wheel. The suspension spring is installed on the suspension support rod, and the suspension support rod is installed on the motor base. The motor base Installed on the bottom plate of the motor, the shaft coupling is connected to the driving reduction motor, and the driving rear wheel is installed on the shaft coupling.

The ball picking mechanism is mainly connected by the ball picking roller brush to the driven pulley, the driven pulley is connected to the driving pulley through the transmission belt, the driving pulley is installed on the one-way thrust bearing, and the one-way thrust bearing is connected to the universal front wheel at the front end of the frame . The pull-rod push handle is designed with three gears, which can be adjusted within a certain range. The power system is mainly composed of left and right driving motors, left and right driving rear wheels and suspension springs. The body integrates the ball picking mechanism, the pull-rod push handle and the power system. In addition, an infrared sensor, a remote control receiving device, a ball storage box, a control circuit board and a battery box are installed. Main functions: 1. Remote control operation to pick up the ball. When encountering obstacles, it will automatically avoid obstacles. When the ball is full, it will send a prompt to inform the operator; 2. Manually pick up the ball. Push the tennis ball picker to pick up the ball. , At the same time, it has the function of ordinary hand-push ball picking machine. The main components of the remote control automatic tennis ball picking machine include body, ball picking roller brush, ball storage box, driving rear wheel, universal front wheel, transmission pulley set, sensor, circuit board, battery and lever type hand push handle and other components.

The ball picking machine is driven by the rear wheel. The left and right driving wheels are respectively driven by two driving motors. When the universal front wheel rotates, it drives the ball picking roller through the transmission pulley group. The transmission pulley group and the universal front wheel are connected by a one-way bearing, which ensures that the ball picking roller rotates and automatically picks up the ball when it is moving forward. Stopping prevents the rollers from reversing and taking the tennis balls out of the case. The picked up tennis balls are temporarily stored in the ball storage box, which is designed as a drawer structure and can be placed and taken out at any time. The rod-type push handle can be adjusted in length according to the change of the height of the ball picker. The length of the push handle is in the range of 70-120cm, and the structure is very flexible. The structural design takes into account the installation of sensors.
