Description

Technical Field

[0001] This invention relates to the field of wolfberry processing technology, specifically to a wolfberry harvesting and impurity removal device. Background Technology

[0002] Goji berries are a specialty economic crop with both medicinal and edible uses. After harvesting, the fruit needs to undergo a series of initial processing steps, including cleaning, grading, dehydration, and preservation. Removing branches, leaves, mud, damaged fruit, and impurities ensures the cleanliness and commercial quality of the fruit, laying the foundation for subsequent drying, grading, packaging, and storage. In actual production, goji berries are mostly harvested manually in the field. Currently, in the initial processing stage after harvesting, due to the large quantity of goji berries harvested, when the fruit is directly dumped into the cleaning device, it is very easy for them to pile up and clump together, making the internal structure... The fruit cannot fully contact the impurity removal structure, resulting in uneven impurity removal and serious impurity residue, making it difficult to meet the cleanliness requirements of subsequent processing. Secondly, most goji berry impurity removal equipment only uses a single dust suction or simple vibration screening method, which has limited effect on cleaning stubborn mud, sand, small branches and leaves and other impurities attached to the surface of goji berries, making it difficult to achieve deep impurity removal. Moreover, the airflow of the equipment is mostly emitted in one go, resulting in low energy utilization and high overall operating costs. In order to address the above problems, the inventors have proposed a goji berry harvesting suction impurity removal device to solve the above problems. Summary of the Invention

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0012] Example: Figure 1-12 As shown, the present invention provides a technical solution: a goji berry picking suction and impurity removal device, including a main frame 1, a uniform feeding component 2 and a discharge frame 3 respectively provided at the top of the main frame 1, a negative pressure dust suction and cleaning component 4 provided below the uniform feeding component 2, a pneumatic vibration generating component 5 provided at the bottom center of the uniform feeding component 2, and a mounting base plate 6 provided on the side of the main frame 1 near the discharge frame 3, and an air explosion component 7 provided on the mounting base plate 6; The uniform feeding component 2 includes an inclined vibration frame 201, which is inclined towards the discharge frame 3. Five sets of first uniformly distributed rods 202 are fixedly installed on the top side of the inclined vibration frame 201 away from the discharge frame 3. Two sets of second uniformly distributed rods 204 are fixedly installed in the middle of the top of the inclined vibration frame 201. By adopting the above technical solution, the inclined vibration frame 201 guides the goji berries forward under vibration. The staggered first uniform distribution rod 202 and the second uniform distribution rod 204 can effectively break up the clumps of material, avoid accumulation, and provide a uniform material flow for subsequent impurity removal.

[0013] The pneumatic vibration generating component 5 includes a vibration housing 501, which is fixedly installed at the bottom center of the inclined vibration frame 201. A central shaft 502 is rotatably connected to the center of the vibration housing 501 via a bearing. An eccentric rotor 503 is fixedly sleeved on the outer wall of the central shaft 502. Three arc-shaped equidistant through holes 504 are opened on one side of the eccentric rotor 503, and two symmetrically distributed counterweights 505 are fixedly installed on the other side of the eccentric rotor 503.

[0014] By adopting the above technical solution, the filtered airflow enters the vibrating housing 501 and directly acts on the integrally formed oblique tooth blades on the outer wall of the eccentric rotor 503, driving the eccentric rotor 503 to rotate at high speed around the central axis 502. The counterweight 505 generates periodic centrifugal force to provide stable vibration force for the tilting vibrating frame 201.

[0015] The gas explosion assembly 7 includes a gas storage cylinder 701 and a valve seat 702. The gas storage cylinder 701 is fixedly installed on the mounting base plate 6. The valve seat 702 is fixedly installed in the middle of the inner wall of the gas storage cylinder 701. A conical valve core 703 is inserted into the middle of the gas storage cylinder 701. A valve stem 704 is vertically sealed and inserted in the middle of the top of the gas storage cylinder 701. The bottom end of the valve stem 704 is fixedly connected to the middle of the conical valve core 703. A return spring 705 is sleeved on the outer wall of the valve stem 704. The two ends of the return spring 705 are respectively connected to the inner wall of the gas storage cylinder 701 and the top of the conical valve core 703.

[0016] By adopting the above technical solution, the gas storage cylinder 701 stores high-pressure purified airflow. When the air pressure overcomes the preload of the return spring 705, the conical valve core 703 opens instantaneously, forming a pulsed steam explosion airflow to powerfully blow away residual impurities on the surface of the goji berries.

[0017] The negative pressure vacuum cleaning component 4 includes a dust collection frame 401, two longitudinally symmetrically arranged primary dust collection frames 402, and a transversely arranged secondary dust collection frame 403. The two primary dust collection frames 402 are symmetrically arranged on both sides of the bottom of the uniform feeding component 2, and the secondary dust collection frame 403 is arranged transversely in the drop area between the inclined vibration frame 201 and the discharge frame 3. The two primary dust collection frames 402 and the secondary dust collection frame 403 are all fixedly connected to the main frame 1 through corresponding supports. The exhaust ends of the two primary dust collection frames 402 and the secondary dust collection frame 403 are connected to the air inlet end of the dust collection frame 401 after the air flows through the air guide pipe.

[0018] By adopting the above technical solution, the first-stage dust collection frame 402 adsorbs the dust shaken off from the inclined vibration frame 201, and the second-stage dust collection frame 403 adsorbs light impurities at the drop point of the material, thus achieving secondary and dual impurity removal. The dust collection frame 401 is filled with clean water, and the water level overflows the bottom of the first-stage guide baffle 407.

[0019] The inner wall of the dust collector frame 401 is fixedly installed with a primary flow guide baffle 407, a baffle 408 and a secondary flow guide baffle 409 that cooperate with each other. The top of the dust collector frame 401 is provided with an inclined top plate 410 that cooperates with the primary flow guide baffle 407.

[0020] By adopting the above technical solution, the airflow containing impurities enters the dust collection frame 401 through the air guide pipe. Under the guidance of the primary flow guide baffle 407, the deflector baffle 408, the secondary flow guide baffle 409 and the inclined top plate 410, a labyrinthine vortex channel is formed. The airflow is forced to pass through the water layer multiple times and form a vortex water flow, so that the dust and water can fully contact, collide and settle.

[0021] A blower 404 is connected through the top of the dust collector frame 401. A servo motor 405 is fixedly installed in the middle of the top of the blower 404. An impeller 406 is fixedly installed at the drive end of the servo motor 405 and rotates inside the blower 404. The exhaust end of the blower 404 is conical and connected to the air inlet end of the vibration housing 501 through a hose.

[0022] By adopting the above technical solution, the servo motor 405 drives the impeller 406 to rotate, providing power for negative pressure dust collection, and at the same time delivering the purified airflow to the vibrating housing 501.

[0023] The end of the vibration housing 501 is sealed and fixedly installed with a cover plate 506, and the exhaust end of the vibration housing 501 is connected to the bottom air inlet end of the air storage cylinder 701 through an air guide pipe.

[0024] By adopting the above technical solution, the airflow after driving vibration is recovered to the air storage cylinder 701, providing a power source for the gas explosion component 7, forming a complete airflow closed loop, and further improving energy utilization.

[0025] A filter screen is provided on the side of the discharge frame 3 near the secondary dust collection frame 403. A mounting plate 706 is provided below the filter screen and is fixedly connected to the main frame 1. Five equally spaced air explosion jet frames 707 are horizontally fixedly installed on the mounting plate 706.

[0026] By adopting the above technical solution, the air explosion jet frame 707 is aligned with the filter screen on the discharge frame 3, so that the airflow generated by the air explosion passes through the filter screen and acts on the wolfberry fruit.

[0027] A gas distributor 708 is fixedly installed at the top center of the mounting base plate 6. The gas distributor 708’s inlet end is connected to the exhaust end of the top of the gas storage cylinder 701 through a gas guide pipe. The five exhaust ends of the gas distributor 708 are respectively connected to the bottom end of the corresponding gas explosion jet frame 707 through gas guide pipes.

[0028] By adopting the above technical solution, the gas distributor 708 evenly distributes the gas explosion airflow to each gas explosion jet frame 707, ensuring that the airflow ejected from the five gas explosion jet frames 707 is the same.

[0029] At the top of the inclined vibration frame 201, between the first uniformly distributed rod 202 and the second uniformly distributed rod 204, and on the side near the discharge frame 3, a plurality of equidistantly distributed first guide plates 203 and second guide plates 205 are fixedly installed, and the first guide plates 203 and the second guide plates 205 are arranged in an alternating manner. The inclined vibration frame 201 is provided with filter screens corresponding to the first guide plates 203 and the second guide plates 205.

[0030] By adopting the above technical solution, the staggered arrangement of the first guide plate 203 and the second guide plate 205 further divides the goji berries into multiple flow channels, allowing the goji berries to be transported in a single row, and the dust is simultaneously shaken off by the filter screen for preliminary pre-removal of impurities.

[0031] The inclined vibration frame 201 has a base frame 206 fixedly installed on both sides of the bottom end. The base frame 206 is fastened to the main frame 1 by bolts, and a rubber buffer pad 207 is provided at the connection between the base frame 206 and the main frame 1.

[0032] By adopting the above technical solution, the rubber buffer pad 207 can isolate vibration transmission, avoid whole-machine resonance, and improve the operational stability and service life of the equipment.

[0033] The discharge frame 3 and the inclined vibration frame 201 are arranged in the same direction and the inclination angle of the discharge frame 3 is greater than that of the inclined vibration frame 201.

[0034] By adopting the above technical solution and setting a certain tilt, it is easy for the wolfberry fruits to slide down and be discharged.

[0035] Working principle: In the actual process of removing impurities from goji berries, the servo motor 405 is first started. The servo motor 405 drives the impeller 406 at its output end to rotate at high speed in the air cylinder 404. During the rotation of the impeller 406, a stable negative pressure is formed inside the air cylinder 404 and the connected air guide pipe, dust collection frame 401, primary dust collection frame 402, and secondary dust collection frame 403. This causes the air inlets of the primary dust collection frame 402 and the secondary dust collection frame 403 to generate continuous and uniform suction. The suction force can be flexibly controlled by adjusting the speed of the servo motor 405 to ensure that only light impurities such as mud and dust on the surface of the goji berries are adsorbed, and the goji berries themselves are not adsorbed, thus avoiding damage to the berries. Outside air enters through the inlets of the primary dust collection frame 402 and the secondary dust collection frame 403, carrying impurities that are subsequently shaken off. This air is then transported through the air duct to the dust collection frame 401. The dust collection frame 401 is pre-filled with clean water, the water level exceeding the bottom of the primary flow guide baffle 407. After entering the dust collection frame 401, the dust-laden airflow, guided by the primary flow guide baffle 407, the baffle 408, the secondary flow guide baffle 409, and the inclined top plate 410, forms a labyrinthine vortex channel. The airflow is forced to pass through the water layer multiple times, creating a vortex flow. This allows the dust and impurities in the airflow to fully contact, collide, and settle with the water, achieving wet purification of the airflow. The purified airflow is clean. Airflow passes through the exhaust end of the air cylinder 404, which is tapered and can increase the airflow velocity. The accelerated airflow is delivered to the vibrating housing 501 through a hose. After entering the vibrating housing 501, the clean airflow directly acts on the integrally formed oblique tooth blades on the outer wall of the eccentric rotor 503, driving the eccentric rotor 503 to rotate at high speed around the central axis 502. Two symmetrically distributed counterweights 505 fixedly installed on the other side of the eccentric rotor 503 generate periodic centrifugal force as the eccentric rotor 503 rotates. The centrifugal force is transmitted to the vibrating housing 501, thereby driving the inclined vibrating frame 201 fixedly connected to the vibrating housing 501 to vibrate continuously and stably. After all components of the device have stabilized and the negative pressure suction and vibration frequency have reached the preset levels, goji berries are fed in. The harvested goji berries are fed into the inclined vibrating frame 201 from the upper end. Once inside, the berries, under continuous vibration, move towards the discharge frame 3 along the inclined direction. Simultaneously, the first and second distribution rods 202 and 204 effectively break up any clumps of berries, preventing accumulation. The berries then pass through the first guide plate 203 and the second guide plate 205. The flow is further divided into multiple single-channel flow to achieve uniform distribution and orderly conveying, ensuring that each goji berry can fully contact the filter and subsequent impurity removal components. During the process of conveying the goji berries on the inclined vibrating frame 201, when the goji berries pass through the filter, the mud, dust and other impurities attached to the surface of the goji berries are shaken off by the vibration. The shaken-off impurities fall down through the filter and the falling dust is adsorbed by the negative pressure suction of the primary dust collection frame 402 and conveyed with the airflow to the dust removal frame 401 to settle, completing the first impurity removal. Goji berries continue to be conveyed to the end along the inclined vibrating frame 201. Because the discharge frame 3 is arranged in the same direction as the inclined vibrating frame 201 and the inclination angle of the discharge frame 3 is greater than that of the inclined vibrating frame 201, the goji berries are briefly suspended in mid-air as they fall from the end of the inclined vibrating frame 201 onto the discharge frame 3. At this time, the secondary dust collection frame 403, which is arranged horizontally in the drop area between the inclined vibrating frame 201 and the discharge frame 3, uses its negative pressure suction to further adsorb the light impurities that are raised during the suspended fall of the goji berries and convey them to the dust collection frame 401 to settle, thus completing the second impurity removal. Meanwhile, the clean airflow discharged from the vibrating housing 501 is transported to the air storage cylinder 701 through the air guide pipe. The airflow is stored and pressurized in the air storage cylinder 701. When the air pressure in the air storage cylinder 701 gradually increases and overcomes the preload force of the return spring 705 sleeved on the outer wall of the valve stem 704, it pushes the conical valve core 703 to move upward and separate from the valve seat 702. The high-pressure airflow in the air storage cylinder 701 is opened instantaneously, forming a pulsed gas explosion airflow. The high-pressure gas explosion airflow is exhausted through the top of the air storage cylinder 701. The gas is conveyed to the gas distributor 708, which evenly distributes the explosive airflow to five equidistant explosive jet frames 707. The pulsed explosive airflow ejected from the explosive jet frames 707 passes through the filter screen and acts on the goji berries on the discharge frame 3, powerfully blowing away the stubborn impurities remaining on the surface of the goji berries. The impurities blown up are then absorbed by the secondary dust collection frame 403. The goji berries slide down along the inclined direction of the discharge frame 3 and finally fall into the subsequent cleaning frame to enter the next cleaning process.
