Description

Technical Field

[0001] The utility model relates to the field of tomato harvesting and seeding equipment, in particular to a device for harvesting and screening tomato improved seeds. Background Technique

[0002] Tomato is a widely planted agricultural crop. Tomatoes need to be harvested and reserved for seeds every year for continuous planting in the next year. When harvesting and reserving tomato seeds, tomatoes with good fruit shapes, good colors, and healthy and vigorous plant growth need to be selected. In actual seed reservation, people will screen according to the size of tomato fruits. Some growers with a large amount of tomato seeds reserved will collect a large number of tomatoes for seed reservation. Then they will classify and reserve the seeds. The most common screening method is to screen according to the size of tomatoes. Tomatoes with moderate particle sizes have good yields and are easier to sell. Only tomatoes with good fruits can be used for the next step of seed particle extraction.

[0003] Currently, when people screen tomatoes during harvesting on the market, they mostly use the method of visual inspection. Tomatoes of roughly the same size are put together. Such a screening method relies on rich experience. Sometimes, due to recognition negligence, some good tomatoes may be mixed with a bad tomato. If it cannot be selected in time, it will affect the quality of tomato seeds in the next year. At the same time, when people reserve tomato seeds now, they basically directly extract the seeds after selecting the tomatoes, and the specific number of tomatoes is not counted. Then, after the seeds are dried, the collection ratio of tomato seeds cannot be mastered either. Content of the Utility Model

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Referring to Figures 1-4 , an embodiment provided by the present utility model: A tomato fine seed harvesting and screening device includes a frame 1. A screening assembly is provided at the top of the frame 1. A bracket 12 is provided in the middle of the frame 1. A material distribution and counting assembly is provided in the middle of the bracket 12. The material distribution and counting assembly is arranged directly below the screening assembly. A material collection assembly is provided at the bottom of the frame 1. The screening assembly is used for screening the size of tomatoes, and the material distribution and counting assembly is used for screening the tomatoes classified by the screening assembly into the material collection assembly;

[0030] The screening component includes a screening trough 4 installed on the top of the vehicle frame 1. A plurality of evenly distributed screening rollers 5 are arranged at the bottom of the screening trough 4. The diameters of the screening rollers 5 gradually decrease from left to right. The screening rollers 5 are rotatably arranged in the screening trough 4. The rotatable arrangement facilitates the feeding of tomatoes.

[0031] The material distribution and counting component includes a plurality of hoppers 7 arranged horizontally in a row on the support 12. Feeding pipes 13 are provided at the bottoms of the hoppers 7. Tomatoes of different diameters are collected uniformly, which is convenient for collecting seeds with stable quality of tomatoes. Ballshells 8 are provided on one side of each feeding pipe 13. A rotating shaft 16 is horizontally rotatably connected at the connection between the ballshell 8 and the feeding pipe 13. Four blades 15 are evenly distributed on the rotating shaft 16. A counter 14 is provided at one end of each rotating shaft 16. The end of the rotating shaft 16 far from the counter 14 is connected to the ballshell 8 through a damping rod. The diameters of the feeding pipe 13, the blade 15 and the ballshell 8 gradually increase from left to right. The device can collect different tomatoes as the diameter of the tomatoes changes. A damping rod is provided on the rotating shaft 16. The damping rod enables the rotating shaft 16 to rotate only when a force is applied and not to rotate when no force is applied. The rotating shaft 16 drives the blade 15 to be adjusted to rotate by a quarter.

[0032] The counters 14 are fixedly connected to the outer wall of the ballshell 8. The material receiving component includes a plurality of drawers 9. Pull handles 10 are fixedly connected to the front sides of the drawers 9. The drawers 9 are arranged in a row from left to right and are correspondingly arranged directly below each feeding pipe 13. On both sides above the drawers 9 and on the vehicle frame 1, multiple groups of rubber pads 11 are arranged from left to right. Each group of rubber pads 11 has two. Each group of rubber pads 11 is symmetrically arranged directly below the feeding pipe 13. The rubber pads 11 are deformed by the force, and the tomatoes fall into the drawers 9. The hoppers 7 are fixedly connected to the bottom of the screening trough 4. A feeding hopper 6 is arranged above one side of the screening trough 4. The feeding hopper 6 is arranged directly above the large-diameter side of the screening roller 5. A handle 3 is fixedly connected above one side of the vehicle frame 1. The handle 3 can push the vehicle frame 1. Wheels 2 are arranged at the four corners of the bottom of the vehicle frame 1. The wheels 2 facilitate the movement of the vehicle frame 1.

[0033] Working principle: Tomatoes enter the feed hopper 6. Then the tomatoes roll down from the large-diameter end of the screening roller 5. The tomatoes are screened by the screening roller 5, and tomatoes in different diameter ranges fall into different discharge hoppers 7. Then the tomatoes fall into the discharge pipe 13 at the lower part of the discharge hopper 7. When the tomatoes pass through the discharge pipe 13, the blocking blade 15 drives the rotating shaft 16 to rotate. The rotating shaft 16 is connected with a damping rod, and the damping rod will prevent the rotating shaft 16 from rotating randomly. After the tomatoes squeeze the rotating shaft 16, the rotating shaft 16 rotates once, and the counter 14 counts once. Before the tomatoes fall from the discharge pipe 13 into the drawer 9, they are blocked by the rubber pad 11 to prevent the tomatoes from falling directly and being damaged. After the tomatoes enter the drawer 9, the drawer 9 can be taken out by pulling the handle 10, and the number of tomatoes collected in each drawer 9 can be known. In this way, the size of the tomatoes depends on mechanical screening, and at the same time, the setting of the number of tomatoes can be mastered, making tomato seed preservation more standardized. Also, the yield of tomato seeds can be calculated in a timely manner according to the number of tomatoes, improving the quality control effect of tomato seed preservation.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
