Description

Technical Field

[0001] The present invention relates to the technical field of plant seed extraction, and particularly relates to a hand-held shovel-type integrated potato seed production device for seed extraction and film coating. Background Art

[0002] The statements herein only provide the background art related to the present invention and do not necessarily constitute the prior art.

[0003] Potatoes have multiple characteristics such as being both food, vegetable, and fruit, and are one of the important food varieties in many countries around the world. They are included among the seven major food crops, ranking only after rice, corn, and wheat. With the continuous growth of the potato industry and the implementation of the staple food strategy, potatoes have become one of the crops with the highest potential for increasing grain production in China. Currently, the market demand for potatoes is increasing continuously, which promotes the healthy development of the potato processing industry.

[0004] The most common propagation method of potatoes is asexual tuber propagation. Currently, the existing planting methods mainly include whole-tuber sowing and cut-tuber planting. Whole tubers have the advantages of drought resistance, strong seedling growth, strong disease resistance, and significant yield increase. However, the cost of whole-tuber sowing is relatively high, which easily leads to waste of seed potato resources, and the income-increasing and yield-increasing advantages of seed potatoes cannot be fully exerted. At the same time, the production and supply efficiency of seed potatoes also cannot meet the needs of large-scale planting.

[0005] For cut-tuber planting, a rotary blade or a reciprocating cutting method is mostly used. Its working principle is based on a simple mechanical cutting principle to divide the seed potato, and multiple tuber pieces with bud eyes can be taken out to meet the planting requirements. However, its cut surface is exposed, which is easily infected and corrupted by bacteria and fungi, resulting in a low germination rate.

[0006] In some simple manual hole-digging operations, operators use ordinary knives to dig out the bud eyes and part of the tuber flesh, and then manually apply a protective agent or a raw pulp that can cool and solidify into a film.

[0007] The above-mentioned planting methods have the following problems:

[0008] (1) Low accuracy and standardization: Whether it is manual hole-digging or existing seed potato processing machinery, it is impossible to accurately control the size, depth of the hole, and the amount of tuber flesh removed. In the later stage, problems such as uneven germination and inconsistent growth rate will occur, affecting the planting quality and effect.

[0009] (2) Uneven coverage of the raw pulp and slow drying: Manual application of the raw pulp cannot ensure its uniform distribution on the cut surface, and it is easy to have inconsistent thickness, affecting the suberization effect. Moreover, natural drying of the raw pulp takes a long time. During this period, the cut surface is easily infected by pathogens and loses moisture, reducing the vitality and stress resistance of the seeds, and at the same time increasing the risk of potato seed infection.

[0010] (3) Low production efficiency: Manual drilling and pulp application are slow and cannot meet the needs of large-scale production. For commercial seed potato processing companies, the high cost limits the industrial development of potatoes.

[0011] (4) Lack of integrated functions: The existing machinery and operation methods all separate the steps of digging holes, covering with raw pulp, and drying. This not only increases the operation process and time, but also easily causes errors and contamination between each link, which is not conducive to ensuring seed quality and production continuity.

[0012] To this end, the present invention provides a spoon-sized handheld shovel-type seed-taking and film-coating integrated potato seed making device that can simultaneously coat the cutting surface to solve the above-mentioned problems. The seed making device of the present invention can be used as a necessary condition for improving the efficiency and quality of potato seed production. Summary of the invention

[0061] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all of the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the invention without making creative efforts belong to the scope of protection of the invention.

[0062] Please refer to Figures 1 to 12 。

[0063] A hand-held shovel-type potato seed-making device for integrated seed-taking and film coating includes a handle 1. One end of the handle 1 is provided with a spoon body 2 for shoveling out the bud-eye potato blocks from the potato. A spoon head 3 is telescopically arranged at one end of the spoon body 2 away from the handle 1.

[0064] In this embodiment, the spoon body 2 has a flat section 201 fixedly connected to the handle 1 and an inclined section 202 bent upward. The low end of the inclined section 202 is fixedly connected to one end of the flat section 201 away from the handle 1. The spoon head 3 is installed at the high end of the inclined section 202 and can move relatively in the inclined direction of the inclined section 202. The front end of the spoon head 3 is a narrow surface (not marked) same as the front end of the spoon body 2, so that the spoon head 3 can dig into the subcutaneous part of the potato synchronously with the spoon body 2 after retracting into the spoon body 2 for seed-taking operation.

[0065] The spoon head 3 is provided with a liquid outlet 4, and an action component is arranged on the handle 1.

[0066] The spoon body 2 is internally provided with an infusion pipe 5 for conveying a flowing raw material.

[0067] In this embodiment, the main component of the raw material is a slurry that can solidify to form a preservative film after cooling. The components of the slurry include, but are not limited to, chitosan, glycerol, and glacial acetic acid. The film-forming thickness at the cut surface of the bud-eye potato block is 0.1 mm, and the film-forming time is 1 - 2 s. It has the advantages of simple formula, environmentally friendly and degradable film components, and can be cast and dried into a film, meeting the requirement of liquid changing into solid.

[0068] When the spoon body 2 touches and presses the potato for seed-taking, the spoon head 3 is pressed and relatively retracts into the spoon body 2, so that the infusion pipe 5 is communicated with the liquid outlet 4, and the action component can drive the raw material in the infusion pipe 5 to be conveyed through the liquid outlet 4 and attached to the cut surface of the bud-eye potato block.

[0069] The handle 1 is provided with an air delivery pipe 15 for conveying a cooling medium. The cooling medium in this embodiment can be normal-temperature air.

[0070] When the spoon head 3 detaches from the potato after seed-taking, the spoon head 3 relatively extends out of the spoon body 2, and the action component can drive the air delivery pipe 15 to convey the cooling medium to the cut surface of the bud-eye potato block, so that the raw material cools and solidifies into a film on the cut surface of the bud-eye potato block.

[0071] In a specific implementation, when removing seeds, the operator holds the handle 1 so that the scoop body 2 and the scoop head 3 are facing the area to be dug on the potato surface, and then operates the handle 1 to dig out the eye potato pieces from the potato.

[0072] During this period, the spoon head 3 will be forced to retract into the spoon body 2 due to the resistance of the potatoes, so that the liquid outlet 4 and the infusion tube 5 remain connected at corresponding positions. During the entire process of digging, the liquid outlet 4 will move relative to the bottom section of the excavated eye potato piece. At this time, with the use of the action component, the raw materials in the infusion tube 5 can be driven to continuously flow through the liquid outlet 4 to and adhere to the section that continues to appear during the excavation of the eye potato piece.

[0073] Subsequently, when the eye potato pieces are completely dug out from the potatoes, the spoon head 3 is separated from the potato surface and extends relatively outward from the spoon body 2, causing the liquid outlet 4 and the liquid infusion tube 5 to be misaligned and unable to maintain connection. At this time, with the use of the action component, the air supply tube 15 can be driven to transport the cooling medium to the cut surface of the eye potato pieces, so that the raw material is cooled and solidified into a film on the cut surface of the eye potato pieces.

[0074] The advantage of this design is that it breaks the original idea and adopts a spoon-type design, which can conveniently and efficiently complete the one-stop seed removal and film covering operation for potatoes. The seeds are removed evenly, and the potato tubers taken out can be regular and smaller, with a higher potato flesh removal rate, which is conducive to transportation and large-scale planting, and also improves the utilization rate of seed potatoes and reduces production costs.

[0075] In one embodiment, the output end of the infusion tube 5 is located on the spoon body 2 near the spoon head 3, and the output end of the infusion tube 5 can be completely blocked by the side wall of the spoon head 3 extending out of the spoon body 2. When the spoon head 3 is retracted into the spoon body 2, the output end of the infusion tube 5 is connected to the input end of the liquid outlet 4.

[0076] A first plug groove 6 for accommodating raw materials is fixed in the handle 1 , and an input end of the infusion tube 5 extends into the handle 1 and is connected to an output end of the first plug groove 6 .

[0077] A first piston 7 is arranged in the first plug groove 6. The action assembly can drive the first piston 7 to move in the first plug groove 6 toward the spoon body 2 to extrude the raw material.

[0078] In this way, when the output end of the infusion tube 5 is connected to the input end of the liquid outlet 4, the first piston 7 is driven by the action component to move toward the spoon body 2 in the first plug groove 6 to squeeze the raw material, so that the raw material is transported to the liquid outlet 4 through the infusion tube 5, so as to continuously flow to and adhere to the cut surface that continues to appear during the excavation of the eye potato tuber.

[0079] In one embodiment, a second plug groove 13 for accommodating a cooling medium is fixed inside the handle 1. The output end of the air delivery pipe 15 is located on the outer wall of the handle 1 close to the spoon body 2, and the input end of the air delivery pipe 15 communicates with the output end of the second plug groove 13.

[0080] A second piston 14 that moves synchronously and in the opposite direction to the first piston 7 is arranged in the second plug groove 13. The action assembly can drive the second piston 14 to move in the second plug groove 13 towards the spoon body 2 to extrude the cooling medium.

[0081] In this way, when the spoon body 2 has just completed the digging of the bud potato pieces from the potato, that is, when the spoon head 3 disengages from the potato and extends out of the spoon body 2 again, at this time, the action assembly drives the second piston 14 to move in the second plug groove 13 towards the spoon body 2 to extrude the cooling medium to be delivered through the air delivery pipe 15 to the cut surface of the bud potato pieces, so that the raw material cools and solidifies into a film on the cut surface of the bud potato pieces.

[0082] In one embodiment, the action assembly includes an operating rod 10. The operating rod 10 is axially parallel to the handle 1 and is slidably inserted into one end of the handle 1 away from the spoon body 2. One end of the operating rod 10 extends into the handle 1 and is fixed with a transmission rod 9. A first connecting rod 8 is fixed on the side of the transmission rod 9 away from the operating rod 10. One end of the first connecting rod 8 is fixed on the outer wall of the first piston 7 away from the spoon body 2.

[0083] A second connecting rod 21 parallel to the first connecting rod 8 is fixed on the outer wall of the second piston 14 away from the spoon body 2.

[0084] Rack bars 19 are axially fixed on the top side of the rod wall of the first connecting rod 8 and the bottom side of the rod wall of the second connecting rod 21 respectively. A gear 20 that cooperates with the two rack bars 19 respectively on the top side and the bottom side is arranged inside the handle 1.

[0085] In this way, when it is necessary to drive the first piston 7 to move towards the spoon body 2, it is only necessary to press the operating rod 10 while holding the handle 1, so that the operating rod 10 drives the first piston 7 to move through the transmission rod 9 and the first connecting rod 8.

[0086] When it is necessary to drive the second piston 14 to move towards the spoon body 2, it is only necessary to pull out the operating rod 10, so that the operating rod 10 drives the transmission rod 9 and the first connecting rod 8 to move in the opposite direction, so that the first connecting rod 8 drives the second connecting rod 21 to move through the rack bar 19 and the gear 20, and the second connecting rod 21 drives the second piston 14 to move closer to the spoon body 2.

[0087] In one embodiment, a first spring (not labeled) is sleeved outside the operating rod 10, and two ends of the first spring are respectively connected to the outer wall of the transmission rod 9 and the corresponding inner wall of the handle 1. When the operating rod 10 is pressed, the first spring will be stretched and deformed, and this deformation can be used to help the operating rod 10 return to its initial state when not pressed. Furthermore, after the bud-eye potato blocks are made by the whole seed production device, only by releasing the operating rod 10, under the action of the elastic recovery of the first spring, the operating rod 10 can automatically move away from the spoon body 2 towards the first piston 7 and the second piston 14 can move closer to the spoon body 2, that is, the cooling medium can be automatically conveyed to the cut surface of the bud-eye potato blocks to help the raw materials quickly cool and solidify into a film on the cut surface of the bud-eye potato blocks.

[0088] In one embodiment, a liquid supplement pipe 12 communicating with the first plug groove 6 is arranged at the bottom of the handle 1, and a first one-way valve 11 capable of unidirectionally closing the output end of the liquid supplement pipe 12 is arranged at the position of the output end of the liquid supplement pipe 12 in the first plug groove 6.

[0089] A second one-way valve 16 capable of unidirectionally closing the output end of the air delivery pipe 15 is arranged at the position of the output end of the air delivery pipe 15 on the side of the handle 1 facing the spoon body 2.

[0090] A gas supplement pipe 18 communicating with the second plug groove 13 is arranged at the top of the handle 1, and a third one-way valve 17 capable of unidirectionally closing the output end of the gas supplement pipe 18 is arranged at the position of the output end of the gas supplement pipe 18 in the second plug groove 13.

[0091] When the first piston 7 moves closer to the spoon body 2, the second piston 14 synchronously moves away from the spoon body 2, the first one-way valve 11 and the second one-way valve 16 are closed, and the third one-way valve 17 is opened;

[0092] When the first piston 7 moves away from the spoon body 2, the second piston 14 synchronously moves closer to the spoon body 2, the first one-way valve 11 and the second one-way valve 16 are opened, and the third one-way valve 17 is closed.

[0093] Thus, when the first piston 7 moves closer to the spoon body 2, the first one-way valve 11 is closed, then the first piston 7 will extrude the raw materials in the first plug groove 6, so that the raw materials can quickly adhere to the cut surface of the bud-eye potato blocks through the liquid delivery pipe 5 and the liquid outlet 4. At the same time, when the second piston 14 synchronously moves away from the spoon body 2, the pressure in the second plug groove 13 will be reduced, resulting in the second one-way valve 16 being automatically closed under the action of the external pressure, and the third one-way valve 17 is opened, so that the external cooling medium can be automatically supplemented into the second plug groove 13 through the gas supplement pipe 18.

[0094] When the first piston 7 moves away from the spoon body 2, the outlet 4 and the infusion tube 5 are misaligned at this time, so that the output end of the infusion tube 5 is blocked by the spoon head 3. The movement of the first piston 7 away from the spoon body 2 will reduce the pressure in the first plug groove 6, causing the first one-way valve 11 to open under the external pressure difference, so as to automatically replenish the raw materials into the first plug groove 6 through the liquid replenishment tube 12. At the same time, the second piston 14 moves synchronously towards the spoon body 2, which will squeeze the cooling medium in the second plug groove 13 to increase the pressure in the second plug groove 13, forcing the second one-way valve 16 to open automatically and the third one-way valve 17 to close automatically, and at the same time, the cooling medium can be automatically transported to the cut surface of the eye potato block through the gas pipe 15, helping the raw materials to quickly cool down and solidify into a film on the cut surface of the eye potato block.

[0095] In one embodiment, a ball valve 29 is installed on the liquid replenishing tube 12. The ball valve 29 can control the opening and closing of the liquid replenishing tube 12, so as to avoid leakage of raw materials in the first plugging tank 6 when the liquid replenishing tank 28 is replaced.

[0096] The bottom of the infusion tube 12 is vertically connected with a first butt joint tube 30 parallel to the axial direction of the handle 1, and the bottom of the handle 1 is axially inserted with a infusion tank 28, and a slot 34 is provided at the bottom of the handle 1. The top of the infusion tank 28 has an insert block (not shown) adapted to be inserted into the slot 34. The cooperation between the insert block and the slot 34 can facilitate the disassembly, assembly and replacement of the infusion tank 28 on the upper handle 1.

[0097] One end of the liquid infusion tank 28 is connected to a second butt joint pipe 31 , and the output end of the second butt joint pipe 31 can be butt-jointed and sleeved on the outside of the input end of the first butt joint pipe 30 .

[0098] A groove 36 is formed around the inner side of the second butt joint 31, and an elastic layer 37 is provided at the notch of the groove 36. The elastic layer 37 can be a rubber layer. The groove 36 contains a pressure medium (not shown), which can be hydraulic oil.

[0099] A clamping groove 35 is provided around the outer circumference of the first butt joint tube 30, and a third plug groove 38 connected to the groove 36 is provided radially in the second butt joint tube 31, and a pressure medium is also contained in the third plug groove 38. The centrifugal end of the third plug groove 38 is axially bent and provided with a third piston 39 that can move axially relative to it, and the first ring body 32 is axially movably sleeved on the outer side of the second butt joint tube 31, and a limiting block 41 is radially fixed on the inner side of the first ring body 32, and a limiting groove 42 that is slidably engaged with the limiting block 41 is axially provided on the outer wall of the second butt joint tube 31, and one end of the limiting block 41 is synchronously connected to the third piston 39 through the fourth connecting rod 40.

[0100] The second butt joint pipe 31 has a second ring body 33 threadedly sleeved on its outer side. The second ring body 33 has a track groove 43 circumferentially formed on a ring surface facing the first ring body 32 . The first ring body 32 is provided with a track block 44 that slidably cooperates with the track groove 43 .

[0101] Thus, when assembling the liquid replenishing tank 28, the liquid replenishing tank 28 is horizontally inserted at the bottom of the handle 1 through the inserting block and the inserting slot 34, and the second docking pipe 31 is sleeved outside the first docking pipe 30. Subsequently, the second ring body 33 is rotated to be in spiral cooperation with the outer wall of the second docking pipe 31, so that under the limiting action of the track block 44 and the track slot 43, the second ring body 33 pushes the first ring body 32 to move axially synchronously with it and approach the first docking pipe 30. Then, the first ring body 32 drives the limiting block 41 to move in the limiting slot 42, and the limiting block 41 drives the third piston 39 to extrude the pressure medium in the third plug slot 38 and the groove 36 through the fourth connecting rod 40, forcing the elastic layer 37 to expand and deform and be hermetically clamped with the clamping slot 35 on the first docking pipe 30, that is, the sealing docking between the first docking pipe 30 and the second docking pipe 31 is completed, and then the installation operation of the liquid replenishing tank 28 on the handle 1 is completed. When it is necessary to remove the old liquid replenishing tank 28 for replacement, only the above steps need to be operated in reverse.

[0102] In one embodiment, a movable slot 22 is formed at the top of the end of the spoon body 2 away from the handle 1, and the spoon head 3 is elastically inserted into the movable slot 22. When the spoon head 3 is not pressed, the spoon head 3 protrudes out of the movable slot 22 relatively. The output end of the infusion tube 5 is located on the slot wall of the movable slot 22.

[0103] Thus, when shoveling the bud eyes and potato pieces on the surface of the potato, the movable slot 22 can provide space for the retraction of the spoon head 3 when it is pressed.

[0104] In one embodiment, a sliding slot 24 is formed inside the spoon body 2, a sliding block 25 is arranged in the sliding slot 24, one end of the spoon head 3 is fixed with a third connecting rod 23, one end of the third connecting rod 23 extends into the sliding slot 24 and is fixed on the sliding block 25, and a second spring (not labeled) is sleeved outside the third connecting rod 23. Two ends of the second spring are respectively connected to the outer wall of the sliding block 25 and the corresponding slot wall of the sliding slot 24. When the spoon head 3 is compressed and inserted into the movable slot 22, the second spring is in a tensile deformation state.

[0105] Thus, when the spoon head 3 retracts relative to the spoon body 2, the sliding block 25 can be driven to move in the sliding slot 24 through the third connecting rod 23, and the second spring is stretched and deformed, so that the stretching deformation of the second spring can be utilized to help the spoon head 3 protrude out of the spoon body 2 again after the spoon head 3 is separated from the potato and is not stressed.

[0106] In one embodiment, a touch switch 26 for touch pressure cooperation with the spoon head 3 is arranged on the slot wall of the movable slot 22 on the side away from the spoon head 3, and a heating plate 27 for conducting heating on the raw material is tightly installed outside the first plug slot 6, and the touch switch 26 is electrically connected to the heating plate 27. In this application, a power supply can be installed inside or outside the handle 1 to provide electric energy for the operation of the heating plate 27.

[0107] Thus, when the spoon head 3 retracts into the movable slot 22 relative to the spoon body 2, it will continuously contact and press the touch switch 26, causing the heating plate 27 to conduct electricity and generate heat, which is then conducted to the raw material in the first plug slot 6 to prevent the raw material from cooling and solidifying and ensure its fluidity.

[0108] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.

[0109] It should be noted that if there are directional indications (such as up and down) involved in the embodiments of the invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0110] In addition, the meaning of "and / or" appearing throughout the text includes three parallel scenarios. Taking "A and / or B" as an example, it includes scenario A, or scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, if there are descriptions such as "first" and "second" in the embodiments of the invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, "a plurality" means more than two. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the invention.
