Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural equipment, in particular to a volva picking suction cup and a device comprising the volva picking suction cup. BACKGROUND

[0002] Volva is a general term for a class of large fungi with typical umbrella-shaped fruiting bodies in the fungal kingdom. Many volvas are edible, such as shiitake mushrooms, mushrooms, and straw mushrooms. In systematic evolution, although these fungi may be of multiple origins, they have been valued by mycologists since early times due to their eye-catching and important economic value. The umbrella-shaped fruiting body is meaty, perishable, and rarely membranous or leathery, including the cap, stem, gill or tube under the cap, annulus in the middle or upper part of the stem, and volva at the base. Volvas are distributed worldwide, from the North Pole to the tropics in forested areas, growing on litter or tree trunks, some growing on marshes, open land, grassland, pasture, or manure, some forming mycorrhizae with certain higher plants, some parasitizing plant roots causing root rot, and a few parasitizing large fungi. From early spring to early winter, different mushrooms appear, and in most areas, late autumn is the peak season for mushroom growth. China has reported about 1 / 5 of the world's known species.

[0003] The artificial cultivation technology of volva is relatively mature, covering multiple common varieties (such as Agaricus bisporus, Pleurotus ostreatus, and Pholiota adiposa) and some rare species (such as the chicken conk). Agaricus bisporus is the mainstream variety in factory production, has strong adaptability, high yield, and requires fermented culture material (straw + cow dung stacked for 20-30 days). Pleurotus ostreatus has a low technical threshold, a short cycle (40-60 days), and requires temperature control for out-of-season cultivation (20-25°C for mycelial growth and 12-16°C for fruiting).

[0004] Mechanized picking technology for volva has developed rapidly in recent years, significantly improving efficiency and reducing reliance on manual labor through intelligent recognition, flexible gripping, and automated control. The fragility of volva caps is mainly reflected in their thin-walled cell structure and low mechanical strength. The cap tissue has a water content of up to 90% and is composed of a single layer of loosely arranged hyphae, and slight pressure or friction can cause cell rupture (such as brown damage to Agaricus bisporus caps under 0.5N / cm 2 pressure). Especially during the mature and open umbrella stage, the cap edge is more prone to cracking due to the degradation of the cuticle layer (the breakage rate increases by 300% compared to the unopened state), which requires the use of negative pressure suction vacuum suction cups for mechanical picking to reduce the risk of damage.

[0005] Recently, the vacuum chuck has been widely used in daily life and industrial automation due to its quick response, lightweight and smooth adsorption process, and plays a key role in the handling of fragile objects, food processing and flat objects. However, in actual engineering applications, for the grabbing objects with complex curvature and delicate material (such as fresh fruit and vegetable agricultural products), the traditional vacuum chuck system has significant technical limitations: first, it is difficult to form an effective seal on irregular curved surfaces, which makes it difficult to maintain vacuum, and gas leakage often occurs during picking, which significantly reduces the adsorption performance; second, there is obvious stress concentration effect at the edge of the chuck, which easily causes plastic deformation marks on the surface of fragile materials, affecting the commercial value of the products.

[0006] Therefore, there is a need for an improved vacuum chuck in the field of agaric picking, which can meet the picking requirements while minimizing damage to the agaric cap. SUMMARY

[0007] To solve the above technical problems, the present application provides the following technical solutions

[0008] In a first aspect, the present application provides an agaric picking chuck, which includes a chuck portion near a picking end, a connecting portion away from the picking end, and an intermediate portion between the chuck portion and the connecting portion.

[0009] Further, the chuck portion includes an open side wall, which defines an opening facing the picking end.

[0010] Further, the open side wall is a funnel-shaped structure.

[0011] Further, the angle α between the extension direction of the open side wall and the center line of the agaric picking chuck is 25°-30°, 30°-35°, 35°-40°, 40°-45°, 45°-60° or 60°-65°.

[0012] Further, the thickness of the open side wall gradually decreases from away from the picking end to close to the picking end, so as to prevent damage to the agaric when the open side wall touches the agaric.

[0013] Further, the cross section of the open side wall includes a straight wall segment near the picking end and a curved wall segment away from the picking end; the straight wall segment is configured to fit the large-diameter cap, and the curved wall segment is configured to fit the small-diameter cap.

[0014] Further, the chuck portion includes a guide structure at the edge of the open side wall near the picking end, which is configured to prevent the open side wall from folding inward when it laterally touches the agaric.

[0015] Further, the guide structure is an outwardly extending annular protruding structure.

[0016] Further, the suction cup part comprises an isolation extension structure extending inward from the connection between the suction cup part and the middle part to form an annular structure, and a through hole is defined in the center of the annular structure.

[0017] Further, the thickness of the isolation extension structure gradually decreases from the outside to the inside.

[0018] Further, the diameter of the through hole is smaller than the inner diameter of the connecting part.

[0019] Further, the middle part is a telescopic structure, and the angle between the telescopic direction of the telescopic structure and the center line of the Morchella picking suction cup is in the range of 0-10°, 10-20° or 20-30°, so as to allow picking of Morchella growing in different directions.

[0020] Further, the middle part is drum-shaped.

[0021] Further, the middle part comprises a reinforcing rib which protrudes outward to enhance the strength of the middle part.

[0022] Further, the connecting part is configured to be sealingly connected to the vacuum pump connecting piece.

[0023] Further, the connecting part comprises a clamping structure configured to be clamped with the vacuum pump connecting piece to prevent the vacuum pump connecting piece from falling off during the adsorption process.

[0024] Further, the Morchella picking suction cup is integrally formed.

[0025] Further, the Morchella picking suction cup is made of an elastic material.

[0026] Further, the elastic material is selected from one or more of the following: silicone, thermoplastic polyurethane rubber, silicone rubber, fluororubber and nitrile rubber.

[0027] In a second aspect, the present application provides a Morchella picking device comprising the Morchella picking suction cup according to the first aspect, a mechanical arm, a vacuum pump and a vacuum pump connecting piece arranged on the mechanical arm for connection with the Morchella picking suction cup.

[0028] The beneficial effects of the present application mainly include the following aspects:

[0029] (1) Significantly reducing picking damage

[0030] Optimizing the opening design: the funnel-shaped opening sidewall (gradual thickness change, combination of straight wall section and curved wall section) can better fit the curved surface profile of the caps of different sizes (large diameter and small diameter), increase the contact area and disperse the adsorption pressure, and avoid the cap bruising or breaking caused by stress concentration of the traditional suction cup.

[0031] Anti-wrinkling structure: The outer flange guiding structure of the open edge can effectively prevent the side wall of the suction cup from folding inward at the moment of suction, avoiding local scratching or crushing of the mushroom cap by the folded edge.

[0032] Protective sealing: The optimized contour fit reduces gas leakage paths, helping to maintain a more stable vacuum degree and avoiding repeated impacts on the mushroom cap caused by frequent air replenishment.

[0033] Isolation extension structure: The ring-shaped isolation extension structure at the connection between the suction cup part and the middle part separates the connection part from the object being sucked, avoiding direct contact between the rigid vacuum pump connector and the surface of the object being sucked, effectively protecting the surface of the object being sucked.

[0034] (2) Improve suction adaptability and stability:

[0035] Curved surface adaptability enhancement: The specially designed side wall angle range and segmented structure (straight wall segment + curved wall segment) enable the suction cup to more effectively adapt to the complex natural curvature changes of the umbrella mushroom cap (especially the edge area), forming a more reliable seal on irregular curved surfaces, solving the problem of maintaining vacuum degree caused by the sealing difficulty of traditional suction cups.

[0036] (3) Enhance adaptability to different growth postures:

[0037] Flexible middle part: The middle part is designed to be flexible within a certain angle range, allowing the suction cup to adaptively adjust the angle during picking to fit the umbrella mushroom that is not vertical or has a certain inclination angle, without the need to forcibly straighten the umbrella mushroom or accurately align, improving the success rate and efficiency of picking.

[0038] (4) Improve structural durability:

[0039] Stiffener design: The outward protruding stiffeners of the middle part significantly enhance the structural strength and fatigue resistance of this part, improving the service life of the suction cup during repeated stretching and deformation, enabling it to withstand high-frequency operation of automated picking equipment.

[0071] The present invention provides a mushroom picking sucker, which includes a sucker portion near the picking end and a connecting portion away from the picking end, with an intermediate portion between the sucker portion and the connecting portion.

[0072] In this article, "umbrella fungi" refers to a class of large fungi with a typical umbrella-shaped fruiting body structure, belonging to the Basidiomycota (and a few Ascomycota) of the fungal kingdom. They have an umbrella-shaped structure, consisting of a cap (umbrella-shaped top) and a stipe (supporting structure). The cap usually has radially arranged gills or tubes (such as Boletus) below it, which are the sites of spore production. For example, mushrooms include shiitake, king oyster, button mushroom, flower mushroom, white jade mushroom, crab mushroom, lion's mane mushroom, oyster mushroom, straw mushroom, matsutake, white bolete, black bolete, yellow bolete, red onion bolete, purple brown bolete, white onion bolete, termite mushroom, bamboo fungus, tea tree mushroom, button mushroom, morel mushroom, white lingzhi mushroom, oyster mushroom, red mushroom, lingzhi, cordyceps, truffle, saddle mushroom, truffle, green-headed mushroom, milk cap mushroom, seafood mushroom, nameko mushroom, bladder mushroom, hazel mushroom, deer antler mushroom, golden ear fungus, chanterelle, coral mushroom, tall mushroom, black pine mushroom, pine mushroom, large red mushroom, or sashimi brown mushroom.

[0073] As used in this article, "picking end" refers to the end closest to the cap of the mushroom when picking it.

[0074] In some embodiments, the agaric mushroom picking suction cup is integrally formed. In other embodiments, the parts of the agaric mushroom picking suction cup are separately formed and then connected together by a suitable material welding method. Non-limiting material welding methods include laser transmission welding: suitable for high molecular materials such as silicone, TPU, etc., the upper layer of the material is added with a light absorber (such as carbon black), and the lower layer remains transparent. After the laser penetrates the upper layer, it generates melting at the interface of the lower layer, forming a molecular level bond (melting depth 0.2-0.5 mm), and the strength can reach more than 80% of the bulk material. Or high-frequency heat sealing: for materials containing polar groups, the molecules are heated by a high-frequency electric field, and local welding is achieved under pressure, with a seam strength > 15 MPa.

[0075] In some embodiments, the agaric mushroom picking suction cup is composed of an elastic material. As used herein, "elastic material" generally refers to elastomer material, which is a general term for polymers with high elasticity, covering types such as rubber and thermoplastic elastomers. According to ASTM standards, rubber specifically refers to materials that are cross-linked by vulcanization to form a state of insolubility but swelling, and elastomers include all polymers with elastic properties. Its chemical structure is usually composed of resin segments and elastic chain segments, combining the resilience of rubber and the processability of plastic, and can be molded by injection molding, extrusion, etc. as needed. For example, the material of the agaric mushroom picking suction cup can be selected from: silicone, thermoplastic polyurethane rubber, silicone rubber, fluororubber, and nitrile rubber.

[0076] In some embodiments, the parts (suction cup part, connecting part, and intermediate part) of the agaric mushroom picking suction cup can be composed of different materials. For example, the suction cup part is composed of soft silicone material, the connecting part is composed of folding-resistant fluororubber or nitrile rubber material, and the connecting part is composed of wear-resistant polyurethane rubber.

[0077] suction cup portion

[0078] In the present application, the "suction cup part" can refer to the part that contacts the cap of the agaric mushroom when the agaric mushroom is suctioned.

[0079] In some embodiments, the suction cup part includes an open side wall that defines an opening facing the picking end.

[0080] In some embodiments, the open side wall is in a funnel-shaped structure.

[0081] In some embodiments, the angle between the extension direction of the opening sidewall and the center line of the umbrella mushroom picking disc is 10°-15°, 15°-20°, 20°-25°, 25°-30°, 30°-35°, 35°-40°, 40°-45°, 45°-60° or 60°-75°, preferably 30°-35°. As used herein, the "extension direction of the opening sidewall" refers to the overall extension direction of the opening sidewall from the picking end to the picking end. As used herein, the "center line" is the axis of symmetry inside a three-dimensional figure, also known as the axis of rotation. It is a line connecting the symmetric points in the figure, and rotating the figure around this line one full turn can result in a completely consistent pattern.

[0082] In some embodiments, the thickness of the opening sidewall gradually decreases from the picking end to the picking end. The decreasing rate of the thickness of the opening sidewall can be fixed or variable.

[0083] In some embodiments, the opening sidewall comprises a straight wall section near the picking end and a curved wall section away from the picking end, and the straight wall section is tangent to the curved wall section at the junction of the two. As used herein, the "straight wall section" refers to the opening sidewall section whose outer surface and inner surface extend in straight lines, and the extension directions of the outer surface and the inner surface can be different, resulting in a change in the thickness of the straight wall section. The "curved wall section" is the opening sidewall section whose outer surface and inner surface extend in curves. In a specific embodiment, the extension directions of the outer surfaces of the straight wall section and the curved wall section are the same and are straight lines, the extension direction of the inner surface of the straight wall section is different from that of the outer surface of the straight wall section, and the extension direction of the inner surface of the curved wall section is a curve. Advantageously, the straight wall section is configured to fit the large-diameter umbrella mushroom, and the curved wall section is configured to fit the small-diameter umbrella mushroom, improving the multi-size adaptability of the umbrella mushroom picking disc of the present application.

[0084] In some embodiments, the disc part comprises a guide structure at the edge of the opening sidewall near the picking end, which is configured to prevent the opening sidewall from folding inward when the umbrella mushroom is adsorbed. Specifically, the guide structure is an outwardly extending annular protruding structure, and the protruding direction can be parallel to the transverse cross-section of the opening.

[0085] In some embodiments, the chuck portion comprises an isolation extension structure extending inwardly from the junction of the chuck portion and the intermediate portion to form an annular structure, with a through hole defined in the center of the annular structure. Advantageously, the diameter of the through hole is smaller than the inner diameter of the junction portion. In some cases, the "inner diameter of the junction portion" as used herein refers to the minimum value of the inner diameter of the junction portion. Alternatively, the diameter of the through hole is smaller than the inner diameter of the clamping structure of the junction portion. The annular isolation extension structure at the junction of the chuck portion and the intermediate portion separates the junction portion from the object being sucked, avoiding direct contact between the rigid vacuum pump connector and the surface of the object being sucked, effectively protecting the surface of the object being sucked. The through hole defined in the center of the annular isolation extension structure forms a gas flow path, ensuring unobstructed gas flow between the junction portion and the chuck portion.

[0086] intermediate portion

[0087] The chuck portion and the junction portion are connected by the intermediate portion.

[0088] In some embodiments, the intermediate portion is configured as a telescopic structure, with the angle between the telescopic direction and the center line of the agaricus picking chuck being within 5°, 10°, 15°, 20°, 25° or 30°, to allow picking of agaricus growing in different directions.

[0089] In some embodiments, the intermediate portion comprises a reinforcing rib protruding outwardly to enhance the strength of the intermediate portion, thereby increasing the number of telescopic times.

[0090] In some embodiments, the intermediate portion is in the shape of a "drum" with narrower ends and a wider center, and the reinforcing rib protrudes outwardly from the widest part of the "drum" (i.e. the most foldable part) to increase the strength of the intermediate portion, thereby increasing the number of telescopic times.

[0091] connection portion

[0092] In the present application, the junction portion is configured to be sealingly connected to the vacuum pump connector.

[0093] In some embodiments, the junction portion comprises a clamping structure with an inner diameter larger than that of other parts of the junction portion, thereby preventing the vacuum pump connector from falling off the agaricus picking chuck during the suction process.

[0094] As used herein, the "vacuum pump connector" refers to the part of the vacuum pump connected to the chuck (specifically the junction portion) for the purpose of realizing gas path connection.

[0096] The suction cup portion 130 comprises an open side wall 131 defining an opening, the open side wall 131 being funnel-shaped. The extension direction of the open side wall 131 forms an included angle a (as shown in the figure) with the center line of the umbrella mushroom picking suction cup (shown by the dotted line). Figure 2 The thickness of the open side wall 131 gradually decreases from the upper end to the lower end in the figure. The open side wall 131 comprises a curved wall section 131a and a straight wall section 131b. The suction cup portion 130 further comprises a guide structure 132 at the edge of the open side wall 131 close to the picking end A, the guide structure 132 being an outwardly extending annular protruding structure. The suction cup portion 130 further comprises an isolation extension structure 133 extending inwardly at the connection between the suction cup portion 130 and the intermediate portion 120 to form an annular structure, the center of the annular structure being defined with a through hole. The diameter of the through hole is smaller than the inner diameter of the connection portion. Figure 2 The intermediate portion 120 is a telescopic structure, the telescopic direction of which is variable within a certain range to allow picking of umbrella mushrooms growing in different directions. The intermediate portion 120 is drum-shaped, the cross-sectional area of which gradually decreases from the center to the two ends. The intermediate portion 120 comprises a reinforcing rib 121 protruding outwardly from the center of the intermediate portion 120 to enhance the strength of the intermediate portion 120, thereby increasing the number of times of telescoping.

[0097] The connection portion 110 has a clamping structure 111 at the connection with the intermediate portion 120, the inner diameter of the clamping structure 111 being larger than the inner diameter of other parts of the connection portion 110.
