Abstract
Description
Technical Field
[0001] This application relates to the field of hazelnut harvesting technology, specifically to a hazelnut harvesting and storage device to prevent damage. Background Technology
[0002] Hazelnuts are the fruit of the hazelnut tree, resembling chestnuts in shape. They have a hard outer shell and a plump, white, round kernel with a fragrant aroma. They have a high oil content, making them exceptionally delicious and leaving a lingering aftertaste, thus becoming one of the most popular nuts and earning the title of "King of Nuts." Currently, manual harvesting accounts for over 60% of the planting cost of hazelnuts, and after harvesting, freshly harvested hazelnuts need to be stored using storage devices.
[0003] However, most current hazelnut harvesting and storage devices can only perform a single storage function. They are not good at removing fallen leaves mixed in with the hazelnuts during harvesting, and at the same time, they are not very effective at protecting the hazelnuts, making them susceptible to mechanical damage. Utility Model Content
[0004] Therefore, this application provides a hazelnut harvesting and storage device to prevent damage, thereby solving the problem that existing devices do not have a good removal function for fallen leaves mixed in with hazelnuts and have a poor protective effect on hazelnuts.
[0005] To achieve the above objectives, this application provides the following technical solution:
[0006] A hazelnut harvesting and storage device to prevent damage includes an outer shell, a sieve plate and a guide plate. A mounting side plate is installed on the outer left side by screws, and a feed hopper is installed through the middle of the upper end of the outer shell.
[0007] A sieve plate is fixedly installed on the inner side of the outer shell, and a pre-made groove is opened through the inside of the sieve plate.
[0008] A guide plate is mounted on the inner right end of the outer casing via a torsion spring shaft, and a collection box is provided inside the lower end of the outer casing, with a rubber sheet pasted inside the collection box.
[0009] Furthermore, a fan is installed on the upper outer side of the mounting side plate, and a guide pipe located on the left side of the sieve plate is fixedly installed on the right outer side of the mounting side plate.
[0010] Furthermore, the sieve plate is inclined and located directly above the collection box.
[0011] Furthermore, the guide plate extends into the interior of the collection box, and the upper end of the collection box is open. A fixing buckle is rotatably installed on the outer right end of the guide plate via a hinge shaft.
[0012] Furthermore, the lower end of the collection box is equipped with casters, and the casters are located on the bottom inner side of the outer casing.
[0013] Furthermore, a discharge pipe is fixedly installed on the upper right outer side of the outer casing, and the discharge pipe is connected to the outer casing.
[0014] Furthermore, the discharge pipe is located directly to the right of the sieve plate.
[0015] Compared with the prior art, this application has at least the following beneficial effects:
[0016] 1. After being screened, the hazelnuts fall onto the outer surface of the guide plate and are guided by the guide plate into the collection box. At this time, the guide plate can reduce the force of the hazelnuts falling, so that the hazelnuts can fall into the collection box more gently. At the same time, the hazelnuts falling into the collection box come into contact with the rubber sheet, which can improve the protection of the hazelnuts through the rubber sheet, thereby reducing the mechanical damage to the hazelnuts.
[0017] 2. The harvested hazelnuts are poured into the shells through the feed hopper, causing them to fall onto the sieve plate. The blower is started to increase the airflow speed and blow the airflow through the guide pipe into the pre-formed trough. At this time, the airflow can blow the light leaves in the hazelnuts into the discharge pipe and blow them out through the discharge pipe, so as to achieve the purpose of screening the leaves.

[0024] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] like Figures 1 to 3 As shown, a hazelnut harvesting and storage device for preventing damage according to the first aspect embodiment of this application includes: a shell 1, a sieve plate 4 and a guide plate 8. A mounting side plate 2 is installed on the outer side of the left end of the shell 1 by screws, and a feed hopper 3 is installed through the middle of the upper end of the shell 1.
[0026] The mounting side plate 2 can be installed and removed with screws, making it convenient to pour the harvested hazelnuts into the outer shell 1 through the feed hopper 3.
[0027] A screen plate 4 is fixedly installed on the inner side of the outer casing 1, and a prefabricated groove 5 is opened through the inside of the screen plate 4. A fan 6 is installed on the outer side of the upper end of the mounting side plate 2, and a guide pipe 7 located on the left side of the screen plate 4 is fixedly installed on the outer side of the right end of the mounting side plate 2. A discharge pipe 13 is fixedly installed on the outer side of the upper right of the outer casing 1, and the discharge pipe 13 is connected to the outer casing 1. The discharge pipe 13 is located directly to the right of the screen plate 4.
[0028] The guide pipe 7 directs the accelerated air into the prefabricated trough 5. The prefabricated trough 5 guides and gathers the air accelerated by the blower 6, facilitating the blowing out of the fallen leaves in the hazelnuts guided by the screen plate 4 through the prefabricated trough 5, and discharging them through the discharge pipe 13, thereby achieving the purpose of screening.
[0029] A guide plate 8 is installed on the right inner side of the outer casing 1 via a torsion spring shaft, and a collection box 9 is provided inside the lower end of the outer casing 1. A rubber sheet 10 is pasted inside the collection box 9.
[0030] Both the precast trough 5 and the guide plate 8 have foam sheets attached to their outer surfaces to protect the falling hazelnuts and reduce impact. The guide plate 8 extends into the collection box 9, and the upper part of the collection box 9 is open, facilitating secondary guidance of the sieved hazelnuts via the guide plate 8, ensuring they fall into the collection box 9 for storage.
[0031] A fixing buckle 12 is rotatably mounted on the outer right side of the guide plate 8 via a hinge shaft, and the lower end of the fixing buckle 12 engages with the right end of the outer shell 1.
[0032] The fixing buckle 12 engages with the outer shell 1 to provide good fixation for the guide plate 8, making it easy to fix it after rotating it to a horizontal position, thereby preventing the guide plate 8 from affecting the extraction and insertion of the collection box 9.
[0033] The sieve plate 4 is inclined and located directly above the collection box 9. The lower end of the collection box 9 is equipped with casters 11, which are located on the bottom inner side of the outer casing 1.
[0034] An extension plate is installed on the lower left side of the outer shell 1 to facilitate the movement of the collection box 9 via the casters 11, so as to facilitate the transfer of hazelnuts stored in the collection box 9.
[0035] Working principle
[0036] First, place the entire assembly stably in the designated position. Then, pull the guide plate 8 downwards using the fixing buckle 12, causing the guide plate 8 to rotate inside the outer shell 1 via the torsion spring shaft until it reaches its highest point, making the guide plate 8 horizontal. At this point, rotate the fixing buckle 12 to engage with the outer shell 1, thereby fixing the angle of the guide plate 8. Then, push the collection box 9 into the interior of the outer shell 1 using the universal wheels 11, so that the collection box 9 is located directly below the sieve plate 4 and the guide plate 8, facilitating the subsequent collection and storage of hazelnuts.
[0037] Rotate the retaining buckle 12 in the opposite direction to release the retaining buckle 12 from the outer shell 1. At this time, the guide plate 8 returns to its original position under the action of the torsion spring shaft, so that the guide plate 8 extends to the inside of the right side of the collection box 9.
[0038] The harvested hazelnuts are poured into the outer shell 1 through the feed hopper 3, causing them to fall onto the sieve plate 4. The blower 6 is started to increase the airflow speed and blow the airflow through the guide pipe 7 into the pre-forming trough 5. At this time, the airflow can blow the light leaves in the hazelnuts into the discharge pipe 13 and blow them out through the discharge pipe 13, so as to achieve the purpose of screening the leaves.
[0039] After screening, the hazelnuts fall onto the outer surface of the guide plate 8 and are guided by the guide plate 8 to fall into the collection box 9. At this time, the guide plate 8 can reduce the force of the hazelnuts falling, so that the hazelnuts can fall into the collection box 9 more gently. At the same time, the hazelnuts falling into the collection box 9 come into contact with the rubber sheet 10, which facilitates the protection of the hazelnuts by the rubber sheet 10, thereby reducing the mechanical damage to the hazelnuts.
[0040] Once a certain amount of hazelnuts has been stored in the collection box 9, lift the guide plate 8 according to the above steps to make it horizontal, and then pull the collection box 9 out of the outer shell 1 for easy transfer.
[0041] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
