[0032] The following will be combined with the attached Figures 1 to 6 The utility model is described in detail, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] The utility model provides a seed vitality detection device under low temperature conditions through improvement. Figure 1 - Figure 6 As shown, it includes a low-temperature culture refrigerator 1, a water source is provided at the bottom of the low-temperature culture refrigerator 1, a partition frame is soaked in the water source, and a roll of paper for wrapping seeds is stored inside each partition frame, a heating component 2 is provided on one side of the low-temperature culture refrigerator 1, and an exhaust component 3 is placed on the upper side of the heating component 2, the exhaust component 3 includes an adsorption box 301, a filter screen 302 is fixedly connected to the adsorption box 301, a fixed plate 303 is fixedly connected to the lower end of the adsorption box 301, and a plurality of adsorption components 4 for adsorbing seeds are arranged inside the fixed plate 303, an exhaust fan 304 is fixedly connected to the upper side wall of the adsorption box 301, and an aperture adjustment component 5 for driving a plurality of adsorption cylinders 401 to rotate is fixedly connected to the side wall of the adsorption box 301.
[0034] In this embodiment: when in use, the adsorption box 301 is placed above the seeds, and then the exhaust fan 304 is started, so that the exhaust fan 304 generates suction to adsorb the seeds, and the filter 302 can prevent impurities in the seeds from being sucked into the exhaust fan 304 or entering the low-temperature cultivation refrigerator 1 through the hose 6, and then the roll of paper is unfolded and laid on the table, and then the handle on the upper surface of the adsorption box 301 is grasped, and the adsorption box 301 is moved to the surface of the unfolded roll of paper, and the exhaust fan 304 is turned off, so that the seeds fall evenly on the surface of the roll of paper, and then the roll of paper is manually rolled up (the roll of paper can be wetted in advance to ensure adhesion to the seeds), and is vertically inserted into the partition frame inside the low-temperature cultivation refrigerator 1 for cultivation. The low-temperature cultivation refrigerator 1 has an intelligent temperature control function (the internal thermostat senses the temperature inside the refrigerator and automatically turns on or off the compressor according to the set temperature range, thereby controlling the temperature inside the refrigerator. The thermostat model is "ETC-961" and this is the prior art).
[0035] In the above embodiment, in order to allow seeds of different sizes to be adsorbed and maintain a certain interval to achieve the purpose of efficient planting, the following methods can be adopted:
[0036] The adsorption component 4 includes an adsorption cylinder 401 rotatably connected to the fixed plate 303, a plurality of cross cavities 402 are bored inside the adsorption cylinder 401, a plurality of adsorption grooves 403 connected to the cross cavities 402 are bored on the side wall of the adsorption cylinder 401, the plurality of adsorption grooves 403 are all configured to be conical, and the adsorption grooves 403 on different sides are of different sizes, the adsorption component 4 also includes a plurality of filter cylinders 404 fixedly connected to the fixed plate 303, and the plurality of filter cylinders 404 are all plugged into the interior of the adsorption cylinder 401, and bristles 405 are fixedly connected to the inner wall of the adsorption cylinder 401.
[0037] In a preferred embodiment, when the exhaust fan 304 is started, air pressure is generated inside the adsorption box 301, causing air flow to enter through the multiple adsorption grooves 403 at the bottom. When the adsorption box 301 is placed on seeds, the seeds will be adsorbed on the adsorption grooves 403 due to the suction force. When the seeds are small, the aperture adjustment component 5 can be used to drive the multiple adsorption cylinders 401 to rotate to achieve adjustment of adsorption grooves 403 of different diameters. At the same time, the filter cylinder 404 can effectively prevent seeds that are too small from being adsorbed into the adsorption box 301. When the adsorption cylinder 401 is rotating, the bristles 405 can also effectively clean the filter cylinder 404.
[0038] The heating component 2 includes a support box 201, and the support box 201 and the adsorption box 301 are magnetically attracted to each other. An air pipe 202 is connected between the support box 201 and the low-temperature culture refrigerator 1. A heating net 203 is fixedly connected inside the support box 201. A hose 6 is connected between the exhaust fan 304 and the low-temperature culture refrigerator 1.
[0039] In a preferred embodiment, since different seeds need to be cultured at a temperature of twenty degrees or above, after the seed planting is completed, the staff can place the adsorption box 301 on the support box 201. The magnetic force between the support box 201 and the adsorption box 301 can improve the sealing between the two. At this time, the heating network 203 and the exhaust fan 304 are started to allow air to pass through the air pipe 202 and the hose 6, and circulate between the low-temperature culture refrigerator 1 and the heating component 2 and the exhaust component 3. The air can be heated when passing through the heating network 203, so that the low-temperature culture refrigerator 1 meets the planting temperature. The low-temperature culture refrigerator 1 is provided with a thermostat to control the temperature within a certain range. When the temperature range is exceeded, the heating network 203 and the exhaust fan 304 will be controlled to stop working, so that the low-temperature culture refrigerator 1 has a wider temperature control function.
[0040] refer to Figure 4 and Figure 5 In a preferred embodiment, the aperture adjustment assembly 5 includes a fixed shell 501 fixedly connected to the side wall of the adsorption box 301, a worm gear 502 fixedly connected to the adsorption cylinder 401 is rotatably connected inside the fixed shell 501, a worm 503 meshing with the worm gear 502 is rotatably connected inside the fixed shell 501, and the worm 503 passes through the fixed shell 501 and is fixedly connected to a knob 504.
[0041] In this embodiment, by rotating the knob 504, the knob 504 drives the worm 503, so that the worm 503 can drive multiple worm wheels 502 to rotate simultaneously, thereby causing multiple adsorption cylinders 401 to rotate synchronously, completing the conversion of multiple adsorption slots 403 with different diameters, thereby adapting to seeds of different sizes.
[0042] Working principle: When detecting the vitality of seeds under low temperature conditions, first, the staff starts the exhaust fan 304 to generate air pressure inside the adsorption box 301, so that the airflow enters from the multiple adsorption grooves 403 at the bottom. When the adsorption box 301 is placed on the seeds, the seeds will be adsorbed on the adsorption grooves 403 by the suction force of the airflow until each adsorption groove 403 adsorbs a seed. Then the adsorption box 301 is placed on the roll of paper, and the exhaust fan 304 is turned off. The seeds fall evenly to the surface of the roll of paper in the low-temperature culture refrigerator 1 due to gravity distribution. Then the roll of paper is rolled up and inserted into the partition frame so that the roll of paper can absorb the water in the low-temperature culture refrigerator 1 and promote the germination of the seeds. The method of wrapping the seeds with the roll of paper can effectively reduce the area occupied by the cultivation, and the equipment can carry out a larger number of seed cultivation experiments at one time.
[0043] When the seeds are generally small, the staff can rotate the knob 504, and the knob 504 drives the worm 503, so that the worm 503 can drive multiple worm wheels 502 to rotate simultaneously, thereby making multiple adsorption cylinders 401 rotate synchronously, completing the conversion of multiple adsorption slots 403 with different diameters to adapt to seeds of different sizes and types. At the same time, the adsorption cylinder 401 can also drive the bristles 405 to clean the filter cylinder 404;
[0044] When conducting low-temperature detection, the staff adjusts the temperature inside the low-temperature culture refrigerator 1 to 7 degrees, observes the germination of the seeds after one week, and then places the adsorption box 301 on the support box 201. The magnetic force between the support box 201 and the adsorption box 301 can improve the sealing between the two. At this time, the heating network 203 and the exhaust fan 304 are started to allow the air to pass through the air pipe 202 and the heating network 203 to achieve the heating effect, and enter the low-temperature culture refrigerator 1 through the hose 6. The air outlet of the hose 6 is located above the water surface. The water source is slowly heated to 25 degrees by hot air to avoid the rapid rise in water temperature affecting the seed germination rate and help the seeds to germinate further. The germination is observed again after three days, so as to determine whether the ungerminated seeds cannot survive.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
