Description

Technical Field

[0001] This utility model relates to the field of tobacco breeding technology, and in particular to a demasing device for tobacco breeding hybridization. Background Technology

[0002] Tobacco hybridization breeding is an important method for cultivating new varieties, and emasculation is a key step in hybridization breeding. Tobacco flowers are hermaphroditic, with both pistils and stamens inside the corolla. The emasculation process requires precise removal of the stamens without damaging the pistils. Currently, the commonly used emasculation methods are manual tweezers emasculation and scissor cutting.

[0003] However, in the existing technology, although the existing manual tweezers emasculation method has high operational precision, the emasculation efficiency is low. It usually requires skilled technicians, otherwise improper operation can easily cause pollen to scatter and cause self-pollination problems. The scissor cutting method is relatively efficient, but the cut stamens are easy to fall off and remain in the flower, still posing a risk of self-pollination, resulting in a less than ideal emasculation effect and making it inconvenient for people to use. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a demasing device for tobacco breeding and hybridization.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a demasking device for tobacco breeding and hybridization, comprising: a first scissor frame and a second scissor frame, a connecting shaft rotatably mounted between the first scissor frame and the second scissor frame, a first scissor head fixedly mounted on one side of the first scissor frame, a second scissor head fixedly mounted on one side of the second scissor frame, a collecting structure provided at the bottom of the first scissor head and the second scissor head, the collecting structure comprising two semi-circular collecting cylinders and two mounting plates, an insert plate fixedly mounted on the outer side of each of the two semi-circular collecting cylinders, the two mounting plates respectively fixedly mounted at the bottom of the first scissor head and the second scissor head, two guide posts fixedly mounted at the bottom of each of the two mounting plates, the four guide posts forming a group of two, a horizontal plate fixedly mounted at the bottom end of each group of two guide posts, a second return spring fixedly mounted at the top of each of the two horizontal plates, a connecting plate fixedly mounted at the top end of each of the two second return springs, and a limit plate fixedly mounted at the top of each of the two connecting plates.

[0006] In a preferred embodiment, a U-shaped pull plate is fixedly installed at the bottom of the connecting plate, and the U-shaped pull plate passes through the horizontal plate and slides in contact with the horizontal plate.

[0007] In a preferred embodiment, the connecting plate is disposed on the outside of the two guide posts, and both guide posts penetrate the connecting plate and slide in contact with the connecting plate.

[0008] In a preferred embodiment, the bottom of the mounting plate is provided with a groove, and the limiting plate is disposed inside the groove and slides in contact with the mounting plate.

[0009] In a preferred embodiment, a slot is provided on one side of the mounting plate, and the size of the mounting plate and the slot are matched.

[0010] In a preferred embodiment, a limiting groove is provided at the bottom of the insert plate, and the size of the limiting plate matches that of the limiting groove.

[0011] In a preferred embodiment, a hand ring is fixedly installed on one side of both the first and second scissor frames, a fixed base is fixedly installed on the top of both the first and second scissor frames, and a return spring is fixedly installed between the two fixed bases.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. The present invention uses two semi-circular collecting tubes that can be combined into a circular collecting tube when the first and second scissor heads come into contact. This ensures that the stamens are collected inside the circular collecting tube when the workers remove the stamens, thus preventing the stamens from falling onto the petals and causing self-pollination. This effectively improves the practicality of the device. 2. By pulling the two U-shaped pull plates, the two connecting plates are moved downwards, thereby removing the limiting plate from the inside of the limiting groove, thus releasing the limiting effect on the insert plate. At this time, the insert plate can be slid out of the slot to remove the semi-circular collecting cylinder for cleaning and replacement. It is simple and convenient to use, making it easy to replace, clean and maintain the semi-circular collecting cylinder, thus improving the effectiveness of the device. 3. The elastic action of the first return spring can move the first and second scissor frames in opposite directions, keeping them in a similar state. This ensures that the two semicircular collecting cylinders are always in a combined state, so that when people cut off the stamens, they can store the stamens without having to force the two semicircular collecting cylinders to combine, making the device easier to use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a demasking device for tobacco breeding and hybridization, comprising: a first scissor frame 11 and a second scissor frame 12, a connecting shaft 13 rotatably mounted between the first scissor frame 11 and the second scissor frame 12, a first scissor head 14 fixedly mounted on one side of the first scissor frame 11, and a second scissor head 15 fixedly mounted on one side of the second scissor frame 12, a collecting structure 2 provided at the bottom of the first scissor head 14 and the second scissor head 15, the collecting structure 2 including two semi-circular collecting cylinders 21 and two mounting plates 23, an insert plate 22 fixedly mounted on the outer side of each of the two semi-circular collecting cylinders 21, and two mounting plates 23 respectively fixedly mounted on the bottom of the first scissor head 14 and the second scissor head 15. Two guide posts 24 are fixedly installed at the bottom of each mounting plate 23. The four guide posts 24 are arranged in pairs. A horizontal plate 25 is fixedly installed at the bottom of each pair of guide posts 24. A second return spring 26 is fixedly installed at the top of each pair of horizontal plates 25. A connecting plate 27 is fixedly installed at the top of each pair of second return springs 26. A limiting plate 28 is fixedly installed at the top of each pair of connecting plates 27. A sliding groove is provided at the bottom of the mounting plate 23. The limiting plate 28 is located inside the sliding groove and slides in contact with the mounting plate 23. A slot 210 is provided on one side of the mounting plate 23. The size of the insertion plate 22 matches the size of the slot 210. A limiting groove 211 is provided at the bottom of the insertion plate 22. The size of the limiting plate 28 matches the size of the limiting groove 211.

[0020] In this embodiment, the two semi-circular collecting cylinders 21 can merge into a single circular collecting cylinder when the first scissor head 14 and the second scissor head 15 come into contact. This ensures that the removed stamens are placed inside the circular collecting cylinder, preventing them from falling onto the petals and causing self-pollination. This effectively improves the practicality of the device. The insert plate 22 is matched to the slot 210, allowing it to be inserted into the slot 210 to effectively place the semi-circular collecting cylinder 21. The limiting groove 211 and the limiting plate 28 are matched, allowing the limiting plate 28 on the top of the connecting plate 27 to be pushed upwards by the elastic action of the second return spring 26 after the semi-circular collecting cylinder 21 is placed. This allows the limiting plate 28 to be inserted into the limiting groove 211 to limit the placement of the insert plate 22, thus securing the semi-circular collecting cylinder 21. The operation is simple, making the device more convenient to use. Example

[0021] like Figure 1-4 As shown, a U-shaped pull plate 29 is fixedly installed at the bottom of the connecting plate 27. The U-shaped pull plate 29 passes through the horizontal plate 25 and slides in contact with the horizontal plate 25. The connecting plate 27 is located on the outside of the two guide posts 24. Both guide posts 24 pass through the connecting plate 27 and slide in contact with the connecting plate 27. Hand rings 16 are fixedly installed on one side of the first scissor frame 11 and the second scissor frame 12. Fixed seats 17 are fixedly installed on the top of the first scissor frame 11 and the second scissor frame 12. A return spring 18 is fixedly installed between the two fixed seats 17.

[0022] In this embodiment, two guide posts 24 penetrate the connecting plate 27 and slide in contact with it. These guide posts 24 limit the movement of the connecting plate 27. The horizontal plate 25 serves two purposes: firstly, it allows the installation of the second return spring 26, providing effective elastic support for the connecting plate 27; secondly, it effectively controls the movement distance of the connecting plate 27. This ensures that when the U-shaped pull plate 29 is pulled, the movement of the limiting plate 28 is confined within the groove of the mounting plate 23, preventing it from moving out of the mounting plate. The slide inside 23 is disengaged to ensure the stability of the structure. The two fixed seats 17 and the first return spring 18 can effectively move the first scissor frame 11 and the second scissor frame 12 in opposite directions through the elastic action of the first return spring 18, so that the first scissor frame 11 and the second scissor frame 12 are kept in a similar state, so that the two semicircular collection cylinders 21 are always in a combined state. Therefore, when people cut off the stamens, they can store the stamens without having to force the two semicircular collection cylinders 21 to combine, making the device more labor-saving to use.

[0023] Working principle: like Figure 1-4 As shown, during use, the operator picks up the device by inserting their thumb and forefinger into the two hand rings 16 respectively. When it is necessary to remove the stamens, the operator uses their fingers to forcefully separate the first scissor frame 11 and the second scissor frame 12, causing the first scissor head 14 and the second scissor head 15 to separate as well. Then, the first scissor head 14 and the second scissor head 15 are placed on both sides of the stamen. At this time, the two semi-circular collection cylinders 21 will be located on both sides of the stamen. Then, the operator moves the first scissor frame 11 and the second scissor frame 12 to drive the first scissor head 14 and the second scissor head 15 to move in opposite directions to cut off the stamens. At the same time as cutting off the stamens, the two semi-circular collection cylinders 21 will merge to form a circular collection cylinder to collect the cut stamens, avoiding the situation where the pollen of the stamens comes into contact with the pistil and causes self-pollination, thus improving the practicality of the device. When the semicircular collecting cylinder 21 needs to be cleaned or replaced after a period of use, pull the two U-shaped pull plates 29 to move the two connecting plates 27 downwards, thereby removing the limiting plate 28 from the inside of the limiting groove 211, thus releasing the limiting effect on the insert plate 22. At this time, the insert plate 22 can be slid out from the slot 210 to remove the semicircular collecting cylinder 21 for cleaning and replacement. It is simple and convenient to use, making it easy to replace, clean and maintain the semicircular collecting cylinder 21, thus improving the effectiveness of the device.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
