Description

Technical Field

[0001] This utility model relates to the field of seed irradiation, and in particular to a protection device for a beam positioning sensor. Background Technology

[0002] In modern agricultural technology, irradiation mutagenesis is a highly efficient breeding method that is widely used in the cultivation of new crop varieties. By bombarding crop seeds with a high-speed ion beam generated by an electron linear accelerator, mutations can be induced in the genetic material inside the seeds, thereby selecting new varieties with superior traits. However, an important step in the irradiation mutagenesis process is to ensure that the seeds are precisely positioned within the irradiation area of ​​the electron beam in order to achieve a uniform and effective irradiation effect.

[0003] In traditional methods, infrared sensors are typically used to position the pallet to ensure that it stops accurately within the electron beam irradiation area during movement. However, this method has a significant problem: infrared sensors are usually installed near or directly within the irradiation area to accurately receive signals; however, prolonged electron beam irradiation can severely damage the infrared sensors, causing them to fail and thus affecting the accuracy of positioning and the efficiency of irradiation.

[0004] Therefore, it is necessary to provide a new beam-down positioning sensor protection device to solve the above-mentioned technical problems. Summary of the Invention

The two connecting plates are respectively installed on both sides of the track. A metal shell is installed on the top of the connecting plate. A lead plate is provided inside the metal shell. An infrared sensor is installed inside the lead plate. A connecting mechanism is installed between the connecting plate and the track.

[0007] Preferably, the connecting structure includes: a groove, a movable block, a spring, a fixed block, a connecting groove, a trapezoidal block, a ramp, and a connecting threaded rod. The connecting plate has a groove at one end facing the track. A movable block is slidably connected to the inner wall of the groove. Springs are symmetrically fixed to both ends of the movable block. One end of each spring is fixedly connected to the inner wall of the groove. A fixed block is fixedly connected to the bottom end of the movable block. A connecting groove is provided on the side of the track facing the connecting plate. A trapezoidal block is slidably connected to the inner wall of the groove. A ramp is provided on one side of the movable block. A connecting threaded rod is threaded inside the connecting plate. One end of the connecting threaded rod is rotatably connected to one side of the trapezoidal block. The inclined surface of the trapezoidal block is in frictional connection with the ramp.

[0008] Preferably, a tray is installed between the two tracks, and seeds are placed on the tray. The two tracks are installed at the bottom of the inside of the frame, and an electron beam emitter is installed inside the frame. Corresponding holes are opened on the side of the two metal shells that are close to each other, and an infrared receiver and an infrared emitter are respectively installed inside the two metal shells.

[0009] Preferably, an adjusting threaded rod is rotatably connected to the top of the connecting plate, and a sliding plate is threadedly connected to one end of the adjusting threaded rod. A positioning plate is fixedly connected to the bottom of the metal shell, and the positioning plate and the sliding plate are fixedly connected by threads.

[0010] Preferably, both the connecting threaded rod and the adjusting threaded rod have an internal hexagonal groove at one end.

[0011] Preferably, the bottom of the fixing block and the inside of the connecting groove are both designed with a frosted finish to facilitate the fixing of the connecting plate.

[0013] Compared with related technologies, the beam-down positioning sensor protection device provided by this utility model has the following beneficial effects:

[0014] Protecting the sensor from radiation damage: By setting a metal shell on the outside of the infrared sensor and embedding a lead plate inside the metal shell, the direct radiation of the electron beam to the sensor is effectively blocked, thereby significantly extending the service life of the sensor and reducing the damage and replacement costs caused by radiation.

[0015] Improved positioning accuracy: The stable installation of the infrared sensor inside the protective shell ensures that it can accurately receive the signal of the tray moving to the irradiation area and immediately feed it back to the track controller to achieve precise positioning of the tray; this helps to improve the uniformity and effectiveness of irradiation mutagenesis and ensure that each seed receives an appropriate amount of irradiation.

[0016] Easy to install and maintain: The device of this utility model has a simple and clear design, a stable and reliable connection structure, and is easy to disassemble and replace; in particular, the design of the internal hexagonal groove makes the adjustment of the connecting threaded rod and the adjusting threaded rod more convenient, allowing users to make fine adjustments according to actual needs, and also facilitating later maintenance and upkeep.

Springs 83 are symmetrically fixed to both ends of the movable block 82. One end of each spring 83 is fixedly connected to the inner wall of the groove 81. A fixed block 84 is fixedly connected to the bottom end of the movable block 82. A groove 81 is provided on the side of the track 2 facing the connecting plate 1. There is a connecting groove 85, and a trapezoidal block 86 is slidably connected to the inner wall of the groove 81. A ramp 87 is opened on one side of the moving block 82. A connecting threaded rod 88 is threadedly connected inside the connecting plate 1. One end of the connecting threaded rod 88 is rotatably connected to one side of the trapezoidal block 86. The inclined surface of the moving block 82 is rubbed against the ramp 87. One end of the connecting threaded rod 88 and the adjusting threaded rod 9 are both provided with an internal hexagonal groove 10 for easy maintenance. The bottom end of the fixing block 84 and the inside of the connecting groove 85 are both frosted to facilitate the fixing of the connecting plate 1.

[0027] Please see Figure 2-5 A tray 5 is installed between the two tracks 2, and seeds are placed on the tray 5. The two tracks 2 are installed at the bottom inside the frame 6. An electron beam emitter 7 is installed inside the frame 6. Corresponding holes are opened on the side of the two metal shells 3 that are close to each other. An infrared receiver and an infrared emitter are installed inside the two metal shells 3 respectively, so as to facilitate the adjustment of the position of the metal shells 3.

[0028] The working principle of the beam-down positioning sensor protection device provided by this utility model is as follows:

[0029] Structural composition and installation:

[0030] The device mainly consists of components such as a connecting plate 1, a metal shell 3, a lead plate 4, an infrared sensor, a tray 5, a track 2, a connecting mechanism 8, and an electron beam emitter 7.

[0031] The connecting plate 1 is securely mounted on both sides of the track 2, while the metal shell 3 is mounted on the top of the connecting plate 1, with a lead plate 4 embedded inside to block the radiation of the electron beam; the infrared sensor is mounted inside the lead plate 4 to ensure that it can receive signals without being affected by radiation.

[0032] The tray 5 is placed between the two tracks 2 to hold the crop seeds to be irradiated; the electron beam emitter 7 is installed at the bottom of the frame 6 and is responsible for generating and emitting an electron beam for irradiation.

[0033] Positioning process:

[0034] When the tray 5, loaded with seeds, moves along the track 2 toward the electron beam irradiation area, the infrared sensor starts to work; the infrared sensor consists of an infrared emitter and an infrared receiver, which are respectively installed on both sides of the metal shell 3 and emit light to each other through holes.

[0035] When tray 5 moves to the predetermined position, that is, above the electron beam irradiation area, the infrared receiver receives the signal emitted by the transmitter; this signal is then converted into an electrical signal and transmitted to the track 2 controller.

[0036] After receiving the signal, the track 2 controller immediately activates the braking mechanism to stop the track 2 from moving, thereby ensuring that the tray 5 can be accurately positioned within the electron beam irradiation area;

[0037] Connection mechanism 8 and adjustment:

[0038] The design of the connecting mechanism 8 allows the connecting plate 1 to be securely mounted on the track 2 and allows for fine-tuning as needed; specifically, through the cooperation of components such as the moving block 82, spring 83, and fixed block 84, as well as the action of the connecting threaded rod 88, the relative position between the connecting plate 1 and the track 2 can be easily adjusted.

[0039] The adjusting threaded rod 9 is used to adjust the height and angle of the metal shell 3 to ensure that the infrared sensor can be accurately aligned with the target position on the tray 5; by rotating the adjusting threaded rod 9, the thread connection depth between it and the bottom of the metal shell 3 can be changed, thereby achieving fine adjustment of the sensor position.

[0040] Irradiation process:

[0041] Once the tray 5 is precisely positioned within the electron beam irradiation area, the electron beam emitter 7 begins to operate, generating a high-speed ion stream to irradiate the seeds; since the infrared sensor is effectively protected, the irradiation process will not cause any damage to it;

[0042] After irradiation is completed, the track 2 controller restarts, driving the tray 5 to continue moving along track 2 to the next process or collection area; throughout the process, the infrared sensor continuously monitors the position of the tray 5 and performs positioning operations again when necessary;

[0043] The outer wall of the metal shell 3 is provided with positioning plates extending to both sides. The positioning plates are fixed to the connecting plate 1 by screws, so that the metal shell 3 and the connecting plate 1 can be detachably connected. Once the metal shell 3 or the infrared sensor inside the metal shell 3 is damaged, it can be easily replaced or disassembled.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
