Description
Technical Field
The invention relates to the technical field of forest fruit harvesting, in particular to a rotatable sea-buckthorn pruning clamping vibration arm with adjustable frequency and rotatable vibration arm for harvesting sea-buckthorn fruits by utilizing a vibration mode aiming at the sea-buckthorn branches with fruits.
Background
The sea-buckthorn is also named as narrow-leaved oleaster and vinegar willow and is mainly planted in provinces such as Xinjiang, inner Mongolia, Hebei, Shanxi, Gansu, Ningxia and Yunguo Sichuan Tibetan in China. The sea-buckthorn has the characteristics of cold resistance, drought resistance, barren resistance and strong weather adaptability; has the functions of preventing wind and fixing sand, maintaining water and soil, fertilizing soil fertility and improving soil ecology; has good ecological benefit, economic benefit and social benefit. The sea-buckthorn fruits are rich in various active substances such as trace elements, amino acids and the like, and with the development of values of sea-buckthorn in all aspects, many enterprises begin to process and produce sea-buckthorn products in China. However, the small diameter of the Chinese sea buckthorn fruit is 5-7 mm, the peel is thin and easy to break, the fruit stem is short, and the branches are also long with thorns, so that the sea buckthorn fruit is not easy to pick and fall off and is difficult to directly pick, and therefore, the fruit is usually cut off and then further frozen and then taken out.
At present, the domestic harvesting mode of the pruned sea-buckthorn branch fruits is generally that after manual pruning and harvesting, fruits are removed by a roller screen fruit removing machine (201721780359.0) after quick freezing at-17 to-20 ℃ to obtain the fruits. The roller screen of the machine can better separate impurities, but the separation process is slow, and the fruit damage rate is high.
Xinjiang agricultural reclamation academy of sciences developed a novel sea buckthorn fruit harvester vibrating head (201620020313.8), can carry out angle modulation, thereby can accurately block the trunk and carry out reciprocating vibration and directly gather the sea buckthorn fruit, but its device amplitude modulation is comparatively complicated, and can not carry out the centre gripping vibration to the branch of different diameters.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a rotatable sea-buckthorn pruning clamping excitation arm which has the characteristics of low fruit damage rate, high production efficiency, simple structure and convenience in control and adjustment.
The invention adopts the following technical scheme: a rotatable sea-buckthorn pruning clamping excitation arm is characterized by comprising a clamping device for clamping cut sea-buckthorn branches, an executing device for fixing and transmitting motion, a power device for driving the excitation arm to do reciprocating motion, and a rotating platform for driving the excitation arm device to rotate; the clamping device comprises a hydraulic cylinder for providing clamping force, a positioning stop block with a fixing function and an upper clamping piece and a lower clamping piece for clamping the sea buckthorn branches; the actuating device comprises a crank slider mechanism consisting of an excitation arm main arm, a supporting box frame, a connecting rod and a crank disk; the power device comprises a speed reducer, a transmission shaft and a direct current motor; the rotary platform comprises a rotary platform capable of rotary motion and a servo motor.
In order to ensure simple structure and stable transmission, the device adopts the direct current motor to provide power and the speed reducer to reduce the speed.
In order to adjust the amplitude and frequency of vibration, the crank disc is provided with limiting holes at different positions so as to generate the length of the crank, and the amplitude can be conveniently adjusted; the direct current motor can adjust different rotating speeds and can conveniently adjust frequency.
In order to ensure that branches with different diameters are clamped, the clamping device adopts a clamping hydraulic cylinder and upper and lower clamping sheets with certain radians to clamp the branches.
The device can recycle the branches after vibrating and fruit peeling through the rotary platform to drive the excitation arm device to rotate, and the branches are collected and recycled by rotating to another station after the peeled fruits are collected.
The invention has the beneficial effects that: the device adopts the crank-slider mechanism to perform reciprocating linear vibration to lead the fruits to fall off, can effectively replace manual picking of the sea buckthorn fruits, and has the advantages of simple structure, high efficiency, stable transmission and the like; the device can adjust the amplitude and frequency, and is convenient for adapting to the vibration harvesting of the sea-buckthorn pruned branch fruits with different diameters and lengths; the device clamps branches by using the hydraulic cylinder and the upper and lower clamping sheets with certain radian, so that the clamping reliability and the adaptability of the device can be ensured; the device can rotate the branch after taking off the fruit to another station through the rotation of rotary platform drive to collect and retrieve, both guaranteed to gather the high efficiency and guaranteed the feature of environmental protection again.
