Description

Technical Field

[0001] This utility model relates to the technical field of film forming machines, and in particular to a controllable spray film forming machine for tomato seeds based on a laboratory environment. Background Technology

[0002] In the field of agricultural research, seed film treatment is an important technical means. By forming a uniform film on the seed surface, seed performance can be improved, such as increasing seed resistance, promoting seed germination, and enhancing seed adaptability to the external environment, thereby improving crop yield and quality.

[0003] In laboratory research related to tomato cultivation, seed film-forming machines are crucial experimental equipment. Their main function is to spray tomato seeds, allowing the film-forming material to adhere evenly to the seed surface and form an ideal film layer. However, existing laboratory seed film-forming machines have significant technical shortcomings in practical applications.

[0004] Existing film-forming machines cannot guarantee that the film-forming material is evenly covered on every tomato seed during the spraying process. This uneven spraying results in some seeds having too much film-forming material on their surface, forming an excessively thick film layer, which affects the seed's air permeability and water absorption, thus inhibiting normal germination. On the other hand, some seeds may have too little film-forming material, failing to form an effective protective film, making it difficult to achieve the expected film-forming effect and fully utilize the advantages of film-forming treatment. The problem of uneven spraying not only reduces the quality of film formation on tomato seeds, affecting the accuracy and reliability of subsequent experimental results, but also increases experimental costs and the number of repeated experiments, thus restricting the research progress of tomato seed film-forming technology and the transformation and application of related scientific research results. Utility Model Content

[0005] To address the aforementioned problems with existing film-forming machines, this paper aims to provide a controllable spray film-forming machine for tomato seeds based on a laboratory environment.

[0006] The specific technical solution is as follows:

[0007] A controllable spray-on film-forming machine for tomato seeds in a laboratory environment includes: a film-forming chamber and a spraying and stirring mechanism. The film-forming chamber is a disc-shaped structure with an open top. The spraying and stirring mechanism is located above the film-forming chamber and can be operably lowered into the film-forming chamber to stir the tomato seeds inside and spray a film-forming agent onto them. The spraying and stirring mechanism includes:

[0008] A rotating tube shaft, which has a top-opening structure and is coaxially arranged with the film-forming chamber, and can be operably rotated and raised / lowered;

[0009] Two connecting pipes are connected to the bottom sidewall of the rotating tube shaft, and each connecting pipe is perpendicular to the rotating tube shaft. Several stirring blades are elastically installed on the bottom sidewall of each connecting pipe along its length. A nozzle is connected to the bottom sidewall of the connecting pipe between two adjacent stirring blades.

[0010] As a further improvement and optimization of this solution, each of the film-forming chambers has several through holes at its bottom, and the size of each through hole is smaller than the size of a tomato seed.

[0011] As a further improvement and optimization of this solution, the stirring blade has a V-shaped structure, and a V-shaped channel is formed between two adjacent stirring blades.

[0012] As a further improvement and optimization of this solution, the openings of the stirring blades on the two connecting pipes face opposite directions.

[0013] As a further improvement and optimization of this solution, the distances between the V-shaped channels formed between the plurality of stirring blades on one of the connecting pipes and the rotating pipe shaft are respectively equal to the distances between the plurality of stirring blades on the other connecting pipe and the rotating pipe shaft.

[0014] As a further improvement and optimization of this solution, each of the stirring blades is connected to the bottom sidewall of the connecting pipe via an elastic telescopic member.

[0015] As a further improvement and optimization of this solution, the elastic telescopic component includes: a rod sleeve and a telescopic rod. The rod sleeve has a bottom-open structure. The top of the telescopic rod is slidably disposed inside the rod sleeve, and the bottom is connected to the stirring blade. Each rod sleeve is provided with a spring, which is connected between the top inner wall of the rod sleeve and the top of the telescopic rod.

[0016] As a further improvement and optimization of this solution, each of the connecting pipes has several spray holes on its bottom sidewall, and the nozzles are respectively connected to the nozzles.

[0017] As a further improvement and optimization of this solution, the nozzles are respectively located directly above the V-shaped channels.

[0018] The positive effects of the above technical solution compared with the existing technology are:

[0019] (1) The spraying and stirring mechanism of this utility model first descends into the film-forming chamber so that several stirring blades elastically contact the bottom of the film-forming chamber. Then, tomato seeds are poured in. The rotating tube shaft rotates, driving the two connecting pipes and several stirring blades to rotate synchronously. At the same time, during the rotation, the film-forming agent is pumped into the opening of the rotating tube shaft and sprayed out through several nozzles. This method of spraying the film-forming agent while stirring can effectively improve the uniformity of spraying the film-forming agent on the tomato seeds.

[0020] (2) During the stirring process, the relative inclined surfaces of two adjacent stirring blades on one of the connecting pipes will cause the tomato seeds to turn inward toward the middle of the V-shaped channel, and at the same time spray the film-forming agent through the nozzle above. When the pointed part of the corresponding stirring blade on the other connecting pipe passes through the inwardly piled tomato seeds, the two inclined surfaces of the stirring blades will cause the inwardly piled tomato seeds to turn outward to both sides again, and at the same time spray the film-forming agent, further improving the uniformity of the film-forming agent spraying.

Figure 4 This is a partial structural cross-sectional view of the spraying and stirring mechanism of a controllable spraying film-forming machine for tomato seeds in a laboratory environment, as described in this utility model. Figure 1 The image shows a preferred embodiment of a controllable spray-type film-forming machine for tomato seeds in a laboratory environment. It includes a film-forming chamber 1 and a spraying and stirring mechanism 2. The film-forming chamber 1 is a disc-shaped structure with an open top. The spraying and stirring mechanism 2 is located above the film-forming chamber 1 and can be operably lowered into the film-forming chamber 1 to stir the tomato seeds within the chamber and spray a film-forming agent onto them. The spraying and stirring mechanism 2 includes a rotating shaft 21 and two connecting pipes 22. The rotating shaft 21 has an open top and is coaxially arranged with the film-forming chamber 1, and can be operably rotated and raised / lowered. The two connecting pipes 22 are respectively connected to the bottom sidewall of the rotating shaft 21, and each connecting pipe 22 is perpendicular to the rotating shaft 21. Several stirring blades 23 are elastically installed along the length of the bottom sidewall of each connecting pipe 22. A nozzle 25 is connected to the bottom sidewall of the connecting pipe 22 between adjacent stirring blades 23.

[0030] In this embodiment, the spraying and stirring mechanism 2 first descends into the film-forming chamber 1 so that several stirring blades 23 elastically contact the bottom of the film-forming chamber 1. Then, tomato seeds are poured in, and the rotating tube shaft 21 rotates, driving the two connecting pipes 22 and several stirring blades 23 to rotate synchronously. At the same time, during the rotation, the film-forming agent is pumped into the opening of the rotating tube shaft 21 and sprayed out through several nozzles 25. This method of spraying the film-forming agent while stirring can effectively improve the uniformity of spraying the film-forming agent onto the tomato seeds.

[0031] Specifically, in this embodiment, the lifting action of the spraying and stirring mechanism 2 can be driven by a drive component such as an electric cylinder or a pneumatic cylinder, and the rotation action can be driven by a servo motor. More specifically, the rotating tube shaft 21 is rotatably mounted on a lifting frame, which can be longitudinally slidably mounted on the body of the film forming machine. The electric cylinder / pneumatic cylinder is mounted on the body and is connected to the lifting frame for transmission, so that the lifting frame can be raised and lowered, thereby driving the spraying and stirring mechanism 2 to be raised and lowered. At the same time, the servo motor is mounted on the lifting frame and can be connected to the rotating tube shaft 21 for transmission through a gear set (preferably a spur gear set) to drive the rotating tube shaft 21 to rotate.

[0032] In one embodiment, a connector is rotatably mounted on the top opening of the rotating tube shaft 21. The connector is sealed to the inner wall of the opening of the rotating tube shaft 21 by a sealing ring. The outlet of the pump is connected to the connector through a pipe, and the inlet of the pump is connected to a storage tank for storing film-forming agents through another pipe.

[0033] Furthermore, as a preferred embodiment, each film-forming chamber 1 has several through holes 11 at its bottom, and the size of each through hole 11 is smaller than the size of a tomato seed, so that excessive film-forming agent can flow out through the through holes 11.

[0034] Even better, a circulation tank can be set on the machine body, and the film-forming chamber 1 is installed on the machine body and located above the circulation tank. The film-forming agent flowing out through the through hole 11 can be concentrated in the circulation tank and then pumped by another pump into the storage tank for recycling.

[0035] Furthermore, in a preferred embodiment, the stirring blade 23 has a V-shaped structure, and a V-shaped channel 26 is formed between two adjacent stirring blades 23. The openings of the stirring blades 23 on the two connecting pipes 22 face opposite directions. The distances between the V-shaped channels 26 formed between the stirring blades 23 on one connecting pipe 22 and the rotating tube shaft 21 are respectively equal to the distances between the stirring blades 23 on the other connecting pipe 22 and the rotating tube shaft 21.

[0036] In this embodiment, during stirring, the relative slopes of the two adjacent stirring blades 23 on one connecting pipe 22 cause the tomato seeds to turn inward toward the center of the V-shaped channel 26, and at the same time spray the film-forming agent through the nozzle 25 above. When the pointed part of the corresponding stirring blade 23 on the other connecting pipe 22 passes through the inwardly piled tomato seeds, the two slopes of the stirring blade 23 cause the inwardly piled tomato seeds to turn outward to both sides again, and at the same time spray the film-forming agent, further improving the uniformity of the film-forming agent spraying.

[0037] Furthermore, as a preferred embodiment, each stirring blade 23 is connected to the bottom side wall of the connecting pipe 22 via an elastic telescopic member 24. In this embodiment, the stirring blade 23 elastically contacts the bottom inner wall of the film-forming chamber 1 via the elastic telescopic member 24, which can avoid affecting contact damage to the stirring blade 23 and the inner wall of the film-forming chamber 1.

[0038] Preferably, the bottom of the stirring blade 23 can also be made of rubber to further reduce frictional damage between it and the film-forming chamber 1.

[0039] Furthermore, as a preferred embodiment, the elastic telescopic member 24 includes: a sleeve 242 and a telescopic rod 241. The sleeve 242 has a bottom-open structure. The top of the telescopic rod 241 is slidably disposed inside the sleeve 242 and the bottom is connected to the stirring blade 23. Each sleeve 242 is provided with a spring 243, which is connected between the top inner wall of the sleeve 242 and the top of the telescopic rod 241.

[0040] Furthermore, as a preferred embodiment, each connecting pipe 22 has a plurality of spray holes on its bottom sidewall, and a plurality of nozzles 25 are respectively connected to the plurality of spray holes.

[0041] Preferably, the nozzle 25 is an existing conventional accessory that can atomize the film-forming agent. More preferably, the nozzle 25 is a solid cone nozzle 25 that produces a solid cone-shaped spray with fine and uniformly distributed spray particles.

[0042] Furthermore, as a preferred embodiment, several nozzles 25 are positioned directly above several V-shaped channels 26 to improve the spraying effect.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
