Description

Technical Field

[0001] The present application belongs to the technical field of agricultural machinery, and specifically relates to a wolfberry sprout picking device. Background Art

[0002] Goji berry sprouts, also known as goji berry heads, goji buds, and beet heads, refer to the young shoots and leaves of the goji berry plant. Research has confirmed that goji berry leaves are rich in protein, amino acids, vitamins, and minerals. Goji berries sprout in early spring, with a slightly bitter taste and a slightly sweet aftertaste, making them refreshing and beneficial for eyesight. They are commonly used by the public to treat yin deficiency, internal heat, dry throat, sore throat, rising liver fire, dizziness, and low-grade fever. The "Compendium of Materia Medica for Dietary Therapy" records that goji berry heads have the effects of strengthening tendons and resisting aging, dispelling wind, nourishing the bones and muscles, and relieving fatigue. Due to their high edible value and high market demand, goji berry sprouts are now cultivated on a large scale. Traditionally, they are harvested by hand, which often involves heavy workload, high harvesting costs, and low efficiency, making them unsuitable for large-scale cultivation.

[0003] To address this issue, the Chinese utility model patent application number CN202320222367.2 discloses a mobile picking machine, which includes a movable floor and a picking machine mounted on the floor. The machine activates an electric push rod during operation. When the double-edged saw moves to a suitable height, the push rod is turned off, and the double-edged saw and motor are activated. The rotation of the motor output shaft drives the roller to rotate. The activation of the double-edged saw cuts the wolfberry buds, which fall into a collection frame. This achieves the effect of automatically moving and picking the wolfberry buds simultaneously. This picking machine is only suitable for working in flat wolfberry fields and can only pick wolfberry buds in a horizontal position. It cannot be flexibly moved to pick wolfberry buds on the side of the wolfberry tree or in other positions.

[0004] Meanwhile, Chinese utility model patent application number CN201420384982.4 discloses a portable tea plucking machine that uses a picking roller to break tea buds by rotation. The negative pressure generated by a motor draws the tea leaves into a storage device. A blower motor at the front of the picking roller further pushes the buds into an adsorption pipe to prevent them from settling. This portable plucking machine can be flexibly applied to tea leaves from different locations. However, during use, the buds may tilt forward or outward under the influence of external forces, resulting in large errors in the length of the picked buds. Furthermore, the picking length is determined entirely by the naked eye, without a reference point, which can also lead to significant length variations. Summary of the Invention

When working, since the seedling supporting mechanism includes a number of parallel distributed cones and the apex of the cone extends out of the picking end, that is, the apex of the cone first extends into the wolfberry sprouts, and as the picking device moves forward, the wolfberry sprouts are pushed to the tail end of the cone. Since the gap becomes narrower, the wolfberry sprouts are gathered and straightened, which can prevent the wolfberry sprouts from tilting or falling in different directions, thereby avoiding large errors in the length of the picked sprouts and the mixing of new sprouts and old stems; at the same time, the laser beam emitted by the auxiliary positioning mechanism shines on the sprouts.

The blower mechanism blows high-pressure wind toward the picking end of the collecting mechanism, which can blow the sprouts picked by the collecting mechanism toward the collection end, preventing the sprouts from falling or accumulating and clogging at the picking end, thereby affecting the normal operation of the picking device.

DETAILED DESCRIPTION

[0030] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, a brief introduction will be given below to the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0031] See Figures 1 to 7 In one embodiment of the present application, a wolfberry bud picking device includes:

[0032] The collecting mechanism 100 includes a picking box 110 and a reciprocating cutting assembly 120. The picking box 110 is a cavity with two through ends, one end is a picking end 130, and the other end is a collecting end 140. The picking end 130 is a rectangular structure. The reciprocating cutting assembly 120 is arranged on the lower surface of the picking end 130; the blowing mechanism 200 is arranged on the upper surface of the picking end 130, and the air outlet of the blowing mechanism 200 extends from the picking end 130 and faces the picking end 130; the seedling supporting mechanism 300, the seedling supporting mechanism 30 0 is arranged on the lower surface of the picking end 130 and is lower than the reciprocating cutting assembly 120. The seedling supporting mechanism 300 includes a plurality of parallel distributed cones 310. The apex of the cone 310 extends out of the picking end 130. The auxiliary positioning mechanism 400 includes a laser emitting rod 410 and a laser receiving rod 420, which are symmetrically arranged on both side walls of the picking end 130 and extend out of the picking end 130. The plane where the laser emitting rod 410 and the laser receiving rod 420 are located is the same plane as the cutting plane of the reciprocating cutting assembly 120.

[0033] The collection mechanism 100 is primarily used for plucking and collecting wolfberry sprouts. The reciprocating cutting assembly 120, located at the plucking end 130, cuts the wolfberry sprouts. As the plucking device advances, more and more wolfberry sprouts accumulate at the plucking end 130, causing blockage and impacting the normal operation of the device. Furthermore, if the plucking sprouts cannot be promptly placed inside the plucking box 110 after being cut, they may fall and be wasted. To this end, the blower mechanism 200 blows high-pressure air toward the plucking end 130, directing the plucking sprouts toward the collection end 140, thereby preventing their accumulation at the plucking end 130. Furthermore, the plucking sprouts are immediately blown into the plucking box 110 for collection, preventing them from falling. The blowing mechanism 200 blows high-pressure wind toward the picking end 130 , and at the same time, it can also blow the forward-falling wolfberry sprouts toward the direction of the reciprocating cutting assembly 120 , thereby assisting the seedling supporting mechanism 300 to further gather and straighten the wolfberry sprouts.

[0034] Since the buds are tender and the branches are soft, they will tilt forward or around under the action of external force, which will lead to large errors in the length of the picked buds and a mixture of old and tender buds. Therefore, a seedling support mechanism 300 is provided. Figure 1As shown, when working, the apex of each cone 310 of the seedling supporting mechanism 300 first extends into the middle of the wolfberry sprouts. As the picking device moves forward, the wolfberry sprouts are pushed to the tail end of the cone 310. As the gap becomes narrower, the wolfberry sprouts are gathered and straightened, and then the reciprocating cutting component 120 cuts the gathered and straightened wolfberry sprouts. In this way, the length of the picked wolfberry sprouts is relatively consistent, avoiding the situation where the wolfberry sprouts tilt in different directions or fall over, resulting in large errors in the length of the sprouts.

[0035] When picking wolfberry sprouts, the principle of "two leaves and one core can be used for tea, and 6 to 8 centimeters can be used for cooking" is generally followed. This is usually done manually with no reference. Some picking devices may also have the sight of the cutting blade blocked when in use. Therefore, an auxiliary positioning mechanism 400 is required, in which a laser emitting rod 410 emits laser light and a laser receiving rod 420 receives the laser light. The two form a laser beam that can serve as a basis for workers to judge the picking height. If the laser beam is higher than the cutting plane of the reciprocating cutting assembly 120, the wolfberry sprouts actually picked will be longer than expected. If the laser beam is lower than the cutting plane of the reciprocating cutting assembly 120, the wolfberry sprouts actually picked will be shorter than expected. Therefore, the plane where the laser emitting rod 410 and the laser receiving rod 420 are located is the same plane as the cutting plane of the reciprocating cutting assembly 120, that is, the height of the laser beam is the height of picking wolfberry sprouts. Then, when working, the worker can see which leaf of the wolfberry sprout the laser beam shines on (for example, two leaves and one heart means two leaves) to judge whether the picking height is reasonable. At the same time, the height can be dynamically adjusted while picking, which is particularly suitable for occasions with undulating ground.

[0036] In a preferred embodiment, the blowing mechanism 200 includes a fan 210, the air outlet of the fan 210 is connected to an air duct 220, the air duct 220 is arranged on the upper surface of the picking end 130 and is parallel to the edge of the upper surface, and the air duct 220 is provided with a plurality of blow pipes 230 at intervals along the length direction, the shape of the blow pipe 230 is arc-shaped, and the outlet of the blow pipe 230 is facing the picking end 130.

[0037] The air blown by the fan 210 is blown toward the picking end 130 through the air duct 220. To ensure that the air can be blown into the picking end 130 without blind spots, a number of blowpipes 230 are installed on the air duct 220, with the outlet of each blowpipe 230 facing the picking end 130. To ensure that more air can enter the picking end 130, the blowpipes 230 are designed to be arc-shaped. This reduces resistance and allows the wind to enter the picking end 130 at an optimal angle. However, the air blown out of a circular outlet typically diverges, which may reduce the effective air volume for blowing the wolfberry sprouts. Therefore, it is preferred that the outlets of several of the blowpipes 230 are also equipped with air guide nozzles 240. The air outlet of each air guide nozzle 240 is flat and faces the picking end 130. The flat air guide nozzles 240 can concentrate the air and blow it evenly parallel to the upper and lower surfaces of the picking end 130, which effectively blows the wolfberry sprouts.

[0038] If the outlet of the blow pipe 230 extends into the picking end 130, it may happen that some wolfberry sprouts at the picking port cannot be effectively blown into the picking end 130. Therefore, as a preference, an extension section is extended from the upper surface of the picking end 130, and the air duct 220 is arranged on the side of the extension section away from the picking end 130, so that the air outlet of the blower mechanism 200 extends out of the picking end 130.

[0039] Furthermore, in the direction from the picking end 130 to the collecting end 140, the blowing direction of the air outlet of the blowing mechanism 200 is inclined downward and intersects with the side of the reciprocating cutting assembly 120 away from the collecting end 140. If the blowing direction is at the front end of the reciprocating cutting assembly 120, then the wolfberry sprouts may not be blown away or some of the wolfberry sprouts may be blown off; if the blowing direction is at the rear end of the reciprocating cutting assembly 120, then some of the wolfberry sprouts may not be blown away, causing some of the wolfberry sprouts to accumulate at the picking end 130. Therefore, please refer to Figure 7 (The arrow in the figure indicates the blowing direction.) The blowing direction should be toward the picking end 130 and intersect or be tangent to the side of the reciprocating cutting assembly 120 facing away from the collecting end 140. This ensures that as soon as the reciprocating cutting assembly 120 cuts the wolfberry sprouts, wind from the outside will blow them into the picking box 110. Furthermore, the air outlet extending from the picking end 130 can also blow forward-leaving wolfberry sprouts toward the reciprocating cutting assembly 120, assisting the seedling supporting mechanism 300 in further gathering and straightening the wolfberry sprouts.

[0040] In another specific embodiment of this application, please combine Figure 1 、 Figure 3 、 Figure 5The above-mentioned wolfberry sprout picking device, the reciprocating cutting assembly 120 includes a fixed toothed blade 121, a cutting toothed blade 122, a first missing gear 124, a second missing gear 125, a first driving member 126 and a second driving member 127, the fixed toothed blade 121 is arranged on the lower surface edge of the picking end 130, the cutting toothed blade 122 is slidably matched with the fixed toothed blade 121, and a rack 123 is provided on the cutting toothed blade 122, the rack 123 is in transmission cooperation with the first missing gear 124 and the second missing gear 125, the first missing gear 124 and the second missing gear 125 rotate in opposite directions, the first driving member 126 drives the first missing gear 124, and the second driving member 127 drives the second missing gear 125. The fixed toothed blade 121 and the cutting toothed blade 122 are both serrated and arranged along the lower edge of the picking end 130. The fixed toothed blade 121 is stationary, while the cutting toothed blade 122 can slide back and forth along the fixed toothed blade 121. Driven by the driving member, the first and second gears 124 rotate in opposite directions, driving the rack 123 to reciprocate, and in turn driving the cutting toothed blade 122 to reciprocate along the fixed toothed blade 121 to cut the wolfberry sprouts.

[0041] In a better case, if Figure 1 The collection end 140 is detachably connected to a collection bag 510, which has a loose, airtight structure. High-pressure air flows through the picking box 110 and into the collection bag 510. If the collection bag 510 were airtight, the high-pressure air would accumulate and swirl inside, causing the wolfberry sprouts to tumble and damage them. Therefore, the collection bag 510 must have a loose, airtight structure. When the collection bag 510 is full of wolfberry sprouts, the collection bag 510 can be removed, the sprouts can be poured out, and then reinstalled to continue working. This makes it easy to operate and allows for flexible handholding and movement.

[0042] See Figure 6 Furthermore, the collection end 140 is detachably connected to a collection box 520, which is equipped with a ventilation component 521. The reason for including the ventilation component 521 in the collection box 520 is as described above. Any ventilation component 521 can be used, such as a ventilation net or ventilation holes. The detachable collection box 520 facilitates timely emptying of the wolfberry sprouts once they are full. Like the collection bag 510, it is easy to operate and can be easily and flexibly moved by hand.

[0043] Furthermore, the top and side walls of the picking box 110 are respectively provided with detachable handles 600 to facilitate the worker's operation with both hands.

[0044] The above disclosure is only a preferred embodiment of the present invention, and it is certainly not intended to limit the scope of the rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the present invention.
