Description

Technical Field

[0001] The present invention relates to the technical field of red date picking and collection, and specifically relates to a portable red date vibration collection device. Background Art

[0002] With the progress of modern technology and the development of society, the mechanization of red date picking has developed to a certain extent. However, in hilly areas or places where large machines cannot reach, manual picking is still required. The method of manually picking red dates by hand is becoming increasingly backward and difficult to meet the requirements of harvesting efficiency and quality.

[0003] Existing red date picking machines include small hand-held picking devices and large red date harvesters. Although small hand-held picking devices are convenient to carry and operate, they also have some problems. On the one hand, the picking efficiency and working range are limited to a certain extent. When operating on the spot, it is difficult to adjust the magnitude of the exciting force, and there is also a certain degree of damage to the tree body of the jujube tree. On the other hand, after the device completes the vibration operation, the picked jujubes fall to the ground randomly, and manual picking is still required, which greatly increases the labor cost. For large red date harvesters, although the automated picking process can be achieved, in mountainous and hilly areas, due to the large size of the equipment, harvesting cannot be carried out, and at this time, a hand-held picking device still needs to be used to assist in harvesting.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0035] Please refer to the attached Figures 1-6, the purpose of this embodiment is to provide a portable red date vibration collection device, including: a collection umbrella 1, a collection part clamping mechanism 2, and an excitation part clamping mechanism 3; the collection umbrella 1 is connected to the collection part clamping mechanism 2, and the collection part clamping mechanism 2 is used to fix the collection umbrella 1 to the tree trunk; in the excitation part clamping mechanism 3, there is a second frame body 31, on which an excitation assembly 38 is arranged. The rotating shaft 381 of the excitation assembly 38 is rotatably installed on the second frame body 31. At the output end of the rotating shaft 381, more than two eccentric blocks are coaxially installed. Each eccentric block has the same shape, and the deflection angle of each eccentric block can be adjusted to change the amplitude generated by the excitation assembly 38. The vibration generated by more than two eccentric blocks is transmitted to the tree trunk; on the rotating shaft 381, there is a shaft hole 382 for inserting the rotating output shaft of the driving device. Preferably, the driving device is a hand-held motor, and the output shaft of the motor is inserted into the shaft hole 382.

[0036] In this embodiment, there are three eccentric blocks, including a first eccentric block 383, a second eccentric block 384, and a third eccentric block 385; at the output end of the rotating shaft 381, there is an installation disk 388, on which at least 4 circumferentially arranged threaded holes 389 are equally spaced; the first eccentric block 383, the second eccentric block 384, and the third eccentric block 385 are sequentially installed on the installation disk 388. The first eccentric block 383, the second eccentric block 384, and the third eccentric block 385 are all fan-shaped structures of 120°. At least 8 through holes 386 are equally spaced in a circumferential arrangement on the installation part of each eccentric block. In this embodiment, the number of through holes 386 is 12. After installation, the central symmetry lines of the fan-shaped surfaces of the first eccentric block 383, the second eccentric block 384, and the third eccentric block 385 coincide or are staggered. Bolts 387 pass through the through holes 386 on the first eccentric block 383, the second eccentric block 384, and the third eccentric block 385 to connect to the threaded holes 389. Those skilled in the art can adjust the through holes 386 on the first eccentric block 383, the second eccentric block 384, and the third eccentric block 385 through which the four bolts 387 pass according to the required amplitude to adjust the included angle between the central symmetry line of each eccentric block and the central symmetry line of the excitation part clamping mechanism 3, thereby changing the magnitude of the vibration amplitude generated by the vibration assembly at the same rotational speed (the rotational speed of the motor can also be adjusted simultaneously), that is, changing the vibration frequency and the vibration amplitude, and realizing the excitation of different jujube trees to complete the picking.

[0037] In a preferred embodiment, there are three eccentric blocks, which include a first eccentric block 383, a second eccentric block 384, and a third eccentric block 385. The first eccentric block 383, the second eccentric block 384, and the third eccentric block 385 are sequentially installed on the mounting disc 388. The first eccentric block 383, the second eccentric block 384, and the third eccentric block 385 are all in a sector structure of 120°. When each eccentric block rotates with the rotating shaft 381, the included angle between the central symmetry line of the eccentric block and the central symmetry line of the excitation part clamping mechanism 3 can be changed under the drive of its individual driving device. During the process of electrically driving the rotation of the rotating shaft 381, the motor speed can be changed to adjust the vibration frequency, and the amplitude can also be changed. The picking can be efficiently completed without manually adjusting each eccentric block.

[0038] Furthermore, the rotating shaft 381 is rotatably installed on the second frame body 31 through a bearing 37. A second lead screw 32 is provided on the second frame body 31 of the excitation part clamping mechanism 3. The second lead screw 32 is used to drive the third caliper 33 and the fourth caliper 34 to approach or move away from each other. A fifth caliper is provided on the surface of the second frame body 31 facing the third caliper 33 and the fourth caliper 34. A third flexible pad 35, a fourth flexible pad 36, and a fifth flexible pad are respectively provided on the third caliper 33, the fourth caliper 34, and the fifth caliper. The tree trunk is clamped from three sides, making the contact between the excitation part clamping mechanism 3 and the tree trunk more stable. With the flexible pads on the calipers, it can ensure that the vibration is efficiently and smoothly transmitted to the tree trunk, reduce the loss of vibration transmission, and at the same time reduce the damage to the jujube tree.

[0039] In addition, a deployment ring 12 is provided at the central position of the collection umbrella 1. The deployment ring 12 is connected to a plurality of support rods 11 on the collection umbrella 1 through positioning pins 13. The deployment ring 12 is connected to the first frame body 21 of the collection part clamping mechanism 2 through a connecting rod 14. A first lead screw 22 is provided on the first frame body 21. The first lead screw 22 is used to drive the first caliper 23 and the second caliper 24 to approach or move away from each other. A first flexible pad 25 and a second flexible pad 26 are respectively provided on the first caliper 23 and the second caliper 24. The collection umbrella 1 is fixed to the tree trunk through the collection part clamping mechanism 2 and can be deployed, facilitating the collection of the jujube fruits that fall during the vibration process, eliminating the process of jujube farmers bending down to pick up. The collection umbrella 1 cooperates with the collection part clamping mechanism 2 and the excitation part clamping mechanism 3 to realize the mechanized picking of the ripe fruits on the jujube tree, greatly reducing the difficulty and operation cost of manual picking, and improving the efficiency and quality of picking red dates.

[0040] When red dates picking work is needed, the date farmers hold this device. First, the collecting part clamping mechanism 2 clamps the trunk of the date tree. When the appropriate height is found, the first lead screw 22 is tightened. After fixation, the collecting umbrella is opened by adjusting the expanding ring 12, so that the collecting umbrella 1 can surround the whole tree to ensure that the falling date fruits can be smoothly received. After the above steps are completed, select a suitable position on the trunk to fix the exciting part clamping mechanism 3. By tightening the second lead screw 32, the calipers and the trunk form a whole. After the device is fixed, the staff holds the motor and inserts it into the shaft hole 382 of the rotating shaft 381 that matches the eccentric block, and starts the motor for picking operation. After the first operation is completed, for the date fruits that have not completely fallen, adjust the angle between the symmetry center line of each eccentric block and the symmetry center line of the exciting part clamping mechanism 3, select a suitable vibration frequency, and vibrate the date tree multiple times until the date fruits completely fall.

[0041] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
