The following describes a one-time use procedure of the present invention with reference to the accompanying drawings:
taking mechanical harvesting of hazelnuts as an example. When the hazelnuts are fully ripe, one part automatically falls to the ground, the other part is hung on branches, and the manual harvesting is very labor-intensive in the past, so that the hazelnuts are harvested by adopting the improved pneumatic forest fruit harvester.
Firstly, the fuel engine 6 is started, and the power of the fuel engine 6 is transmitted to the negative pressure centrifugal fan 5 through the first belt pulley transmission mechanism 10, so that the negative pressure centrifugal fan 5 is driven to rotate.
When the negative pressure centrifugal fan 5 rotates, the upper cavity 23 and the fruit suction pipe 3 in the harvesting box 2 form negative pressure; meanwhile, in the advancing process of the forest fruit harvester, when the picking head 4 is used for picking hazelnut fruits on branches or on the ground, the handle 12 is held by hands, the shell 11 of the picking head 4 is aligned to the hazelnut fruits, at the moment, the brush head driving motor 15 drives the rotating shaft 14 to rotate through the second belt pulley transmission mechanism 18 and the third belt pulley transmission mechanism 19, and then the picking brush head 13 is driven to rotate, and eccentric vibration is generated in the rotating process of the picking brush head 13 due to the mass eccentric structure of the picking brush head 13, so that the hazelnut fruits on the branches are promoted to fall off and the disturbance of the hazelnut fruits on the ground is improved. In addition, in order to further improve the disturbance effect when the hazelnut fruits are picked, the turbulent blower 20 needs to be started, and the hazelnut fruits are subjected to enhanced disturbance through the turbulent blower 20, so that the hazelnut fruits are more easily sucked into the fruit suction pipe 3.
Along with the negative pressure suction effect, hazelnut fruits mixed with sundries such as branches and leaves enter an upper cavity 23 in the harvesting box 2 through the fruit suction pipe 3, the heavy hazelnut fruits firstly fall onto the fruit drop guide baffle 25 and directly slide into the impeller type fruit drop buffer 26 through the fruit drop guide baffle 25, one part of sundries such as the light branches and leaves also slide into the impeller type fruit drop buffer 26, the other part of impurities such as the small-size gravel can be blocked by the filter screen plate 27 and adsorbed on the front surface of the filter screen plate 27, and the impurities such as the small-size gravel directly enter the negative pressure centrifugal fan 5 through the filter screen plate 27 and are directly discharged from an air outlet of the negative pressure centrifugal fan 5. In addition, when the foreign matters adsorbed on the front surface of the filter screen plate 27 are too much, the negative pressure adsorption effect is affected, at this time, the roller brush 28 can be started, the cleaning brush hair 29 cleans the foreign matters such as branches and leaves from the front surface of the filter screen plate 27, and the cleaned foreign matters such as branches and leaves can directly fall into the impeller type fruit dropping buffer 26 below.
After a certain amount of hazelnut fruits mixed with sundries such as branches and leaves are accumulated in the impeller type drop buffer 26, the drop buffer impeller 30 is started to enable the drop buffer impeller 30 to rotate 180 degrees, at this time, the hazelnut fruits and the sundries finish the process of transferring from the upper cavity 23 to the lower cavity 24, as the hazelnut fruits are heavy, the hazelnut fruits can directly fall into the fruit collecting chamber 32 for storing, and for sundries such as lighter branches and leaves mixed in the hazelnut fruits, the sundries such as branches and leaves can be directly blown off and enter the sundries chamber 33 beyond the sundries guide partition 34 in the falling process of the branches and leaves under the blowing action of the axial flow fan 7, so that the separation of the sundries and the hazelnut fruits is realized.
With the continuous harvesting operation, after a certain amount of hazelnuts are stored in the fruit collecting chamber 32, the fruit collecting chamber door on the harvesting box 2 can be opened, the collected hazelnuts and sundries are taken out together, and the harvesting operation of the hazelnuts can be restarted after the chamber door is closed.
The embodiments are not intended to limit the scope of the invention, but rather are intended to cover all equivalent implementations or modifications that can be made without departing from the scope of the invention.
