Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fruit harvesting equipment, and specifically relates to a cleaning device for picking up fruits. BACKGROUND

[0002] Fruit harvesting generally adopts mechanical vibration or manual knocking to make the fruits on the tree fall down, and then the fruits are picked up and classified by a ground fruit picking and cleaning device. This method can be used for harvesting fruits such as jujubes, walnuts, and tea fruits, which are planted in an environment suitable for agricultural operations.

[0003] Traditional ground fruit harvesting uses negative pressure and a rolling brush to convey the ground fruits and impurities to a screen or a grid arranged obliquely, and the fruits are vibrated to remove small impurities during the rolling process. Larger fruits roll along the screen or grid to a collection mechanism. For example, a jujube picking device disclosed in Chinese Patent No. ZL202220617404.5 includes a driving vehicle, a frame, a cleaning mechanism, a conveyor belt, a feeding driving mechanism, a screening roller way, and a collection tank. The discharge end of the conveyor belt is arranged directly above the feeding end of the screening roller way, and the discharge end of the screening roller way extends to the slot of the collection tank. A plurality of shovels are arranged on the conveyor belt. The shovels are arranged on the outer side of the conveyor belt. During the forward movement of the driving vehicle, the jujubes on the ground are swept to the conveyor belt with shovels by the cleaning device. The conveyor belt is driven by the feeding driving mechanism to move and feed the jujubes to the screening roller way. The screening roller way screens out the leaves and dust in the jujubes, and sends the screened jujubes to the collection tank. This device has low energy consumption, ensures the quality of jujube picking, removes leaves and dust, and saves time and effort.

[0004] However, this technical solution installs the cleaning mechanism for cleaning and picking up on the front end of the driving vehicle and installs the frame for cleaning and screening on the driving vehicle. First, the driving vehicle cannot be used for other purposes after installing the cleaning and screening mechanisms, and can only be used for picking up jujubes, which has a small application range. If other functions are needed, a separate device needs to be purchased, which increases the production cost and the cost of maintenance, repair, and storage. Second, the cleaning and screening in this technical solution only remove impurities by vibrating the feeding roller and the vibration motor. The impurity removal effect is limited, and the speed and flow of jujubes entering the feeding roller need to be controlled. When the speed is high or the flow of jujubes entering is large, some impurities may fall into the collection tank without being screened, which affects the cleaning effect. SUMMARY

[0012] The power provided by the driving mechanism is transmitted to the first transmission shaft and the second transmission shaft through the T-shaped steering box. The movement direction of the power shaft is converted into torque in two different positions and directions of the first transmission shaft and the second transmission shaft, and is outputted.

[0016] The two first driving wheels are driven to rotate by the third transmission shaft, the first driving wheel drives the first driven wheel to rotate through the first transmission chain, and the two first transmission chains keep synchronous movement, so that the first cross rod on the first transmission chain continuously moves with the first transmission chain, and the picking teeth on the first cross rod also move with the first transmission chain.

[0017] As a preferred, the bogie is hinged to one end of the frame close to the driving mechanism, and the driving mechanism is provided with a connecting frame close to the frame, and the bogie is hinged to the connecting frame.

[0018] The power source in the frame relies on the power shaft on the driving mechanism, and the traction force on the frame is provided by the hinging of the connecting frame at the tail of the driving mechanism and the bogie at the front end of the frame, so that the driving mechanism can not only drive the fruit picking assembly, the lifting assembly and the cleaning assembly in the frame to operate, but also can move the frame through the traction of the driving mechanism, and meanwhile, the power and the traction force provided to the frame do not interfere with each other, the turning is facilitated, and the turning radius is reduced.
