Description

Technical Field

[0001] This utility model relates to the field of shaking harvester technology, and in particular to a shaking harvester for dwarf and densely planted jujubes based on an electric tricycle. Background Technology

[0002] Harvesting jujubes is the most labor-intensive and costly stage of jujube production. Although various research institutions, institutes, and enterprises have demonstrated and promoted different types of jujube harvesters to farmers and the market, such as self-propelled straddle-type, manually operated pneumatic suction-type, and brush-type harvesters, their widespread adoption has been limited due to factors such as complex machine structures, high prices, and high loss rates. Currently, jujube farmers still commonly use methods such as threshing, manual leaf sweeping, or mechanical leaf blowing followed by manual picking, which are labor-intensive, inefficient, increase production costs, and reduce farmers' income.

[0006] The mobile vehicle includes a three-wheeled electric vehicle frame, a drive wheel at the bottom of the three-wheeled electric vehicle frame, a movable seat at one end of the three-wheeled electric vehicle frame, a steering handle on the side of the three-wheeled electric vehicle frame near the movable seat, and a steering wheel at the bottom of the steering handle.

[0007] The lifting device includes a height adjustment screw, crank, and rocker arm that are rotatably connected to the frame of the three-wheeled electric vehicle. A first-stage movable main arm is threadedly connected to the height adjustment screw, crank, and rocker arm. A second-stage movable main arm is rotatably connected to the side of the first-stage movable main arm away from the height adjustment screw, crank, and rocker arm.

[0008] The clamping device includes a movable support arm rotatably connected to the second-stage movable main arm, a semi-circular arc fixed chuck is fixedly provided on the second-stage movable main arm, a semi-circular arc movable chuck is fixedly provided on the movable support arm, and a clamping screw crank rocker is provided between the second-stage movable main arm and the movable support arm.

[0009] Several U-shaped umbrella frames are fixedly connected to the second-stage movable main arm and movable support arm, and U-shaped umbrellas are provided between the U-shaped umbrella frames.

[0010] Furthermore, the control device includes a V power supply fixedly installed at the bottom of the three-wheeled electric vehicle frame, and the top of the steering handle is equipped with a trolley drive control knob and a vibration machine control knob.

[0011] Furthermore, the single eccentric block type excitation device includes a V DC motor fixedly installed on the second-stage movable main arm, and the output shaft of the V DC motor is provided with a rocking eccentric block.

[0012] Furthermore, the V power supply is electrically connected to the V DC motor, the trolley drive control knob, and the rocking vibration machine control knob, respectively.

[0013] Furthermore, the semi-circular fixed chuck and the semi-circular movable chuck are arranged in a rotationally symmetrical manner.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model discloses a dwarf and densely planted jujube shaking harvester based on an electric tricycle. The hydraulic and mechanical shaking mechanisms have been designed to be lightweight. The DC motor drives the eccentric block to generate shaking, which simplifies the structure of the machine and reduces the cost and difficulty of operation. The U-shaped umbrella-shaped catcher eliminates or reduces the step of jujube farmers bending over to pick up the jujubes. The machine is lightweight, efficient, reliable and inexpensive.

[0016] The shaking frequency of the machine can be adjusted within a certain range by changing the motor speed according to the age of the tree or the diameter of the trunk, so as to maximize the shaking of the red dates hanging on the jujube heads and shake them to fall into the U-shaped collection umbrella and be collected into the frame, making it highly adaptable.

[0017] The machine is lightweight and compact, suitable for dwarf and densely planted jujube trees with small row spacing. It can be modified from existing ordinary electric tricycles. The two rotary switch switches can independently control the drive of the trolley (forward or backward) and the rotation of the vibrating motor. The movable seat can be switched forward and backward, realizing the forward and backward riding of the tricycle, which is convenient for clamping and harvesting operations.

[0024] like Figure 1 As shown, a dwarf and densely planted jujube shaking harvester based on an electric tricycle includes a mobile vehicle, which includes a three-wheeled electric vehicle frame 4. The bottom of the three-wheeled electric vehicle frame 4 is provided with drive wheels 2. One end of the three-wheeled electric vehicle frame 4 is provided with a movable seat 5. The movable seat 5 can be rotated forward and backward to realize the forward and backward riding of the three-wheeled vehicle. The side of the three-wheeled electric vehicle frame 4 near the movable seat 5 is provided with a steering handle 6, and the bottom of the steering handle 6 is provided with a steering wheel 3.

[0025] A lifting device is provided on one side of the mobile vehicle. The lifting device includes a height adjustment screw, crank, and rocker arm 9 that is rotatably connected to the frame 4 of the three-wheeled electric vehicle. A first-stage movable main arm 10 is threadedly connected to the height adjustment screw, crank, and rocker arm 9. A second-stage movable main arm 13 is rotatably connected to the side of the first-stage movable main arm 10 away from the height adjustment screw, crank, and rocker arm 9.

[0026] By cranking the height adjustment screw crank rocker 9, the first-stage movable main arm 10 is raised and lowered.

[0027] The lifting device is equipped with a clamping device, which includes a movable support arm 18 rotatably connected to the second-stage movable main arm 13. A semi-circular fixed chuck 14 is fixedly provided on the second-stage movable main arm 13, and a semi-circular movable chuck 17 is fixedly provided on the movable support arm 18. The semi-circular fixed chuck 14 and the semi-circular movable chuck 17 are arranged in a rotationally symmetrical manner. A clamping screw crank rocker 19 is provided between the second-stage movable main arm 13 and the movable support arm 18.

[0028] The clamping screw crank rocker 19 is rotatably connected to the second-stage movable main arm 13. The movable support arm 18 has an elongated hole. A rotating sleeve (not shown in the figure) is threaded onto the clamping screw crank rocker 19. The rotating sleeve is rotatably and slidably connected to the elongated hole. When the clamping screw crank rocker 19 is rotated, the movable support arm 18 can rotate.

[0029] The jujube tree trunk is placed between the semi-circular fixed clamp 14 and the semi-circular movable clamp 17 by the clamping mechanism, and the jujube tree trunk is fixed by shaking the clamping screw crank rocker 19.

[0030] Several U-shaped umbrella frames 12 are fixedly connected to the second-level movable main arm 13 and movable support arm 18, and U-shaped umbrellas 11 are provided between the U-shaped umbrella frames 12.

[0031] The mobile vehicle is equipped with a control device, which includes a 48V power supply 1 fixedly installed at the bottom of the three-wheeled electric vehicle frame 4. The top of the steering handle 6 is equipped with a trolley drive control knob 7 and a vibration motor control knob 8. By using the trolley drive control knob 7 and the vibration motor control knob 8, the forward or backward movement of the trolley and the rotation of the 48V DC motor 16 can be controlled independently.

[0032] The lifting device is equipped with a single eccentric block excitation device, which includes a 48V DC motor 16 fixedly installed on the second-stage movable main arm 13.

[0033] By turning the control knob 8 of the vibratory motor, the 48V DC motor 16 rotates, which in turn drives the vibratory eccentric block 15 to rotate, generating vibration and shaking the tree. The fallen jujubes fall into the U-shaped collection umbrella 11, thus completing the harvest of one tree.

[0034] This utility model discloses a dwarfing and densely planted jujube shaking harvester based on an electric tricycle. Powered by the 48V DC power of the electric tricycle, the machine requires manual assistance to clamp the tree trunk with a clamping device, install a U-shaped collection umbrella, and activate a single eccentric block vibrating device to shake the tree.
