Description

Technical Field

[0001] The utility model belongs to the technical field of seed detection, in particular to a constant temperature device used for seed detection. Background Art

[0002] Seeds are the reproductive system of seed plants and play a vital role in species continuity. Seed testing involves placing a sample of seeds in a specific environment for testing. To improve temperature uniformity, specific treatments are performed. However, traditional constant temperature equipment typically only blows air from one side, lacking penetrating airflow and thus failing to achieve effective temperature uniformity.

[0003] A search revealed a Chinese patent document (authorization publication number CN210745949U) describing a constant-temperature germination device for Chinese cabbage seeds. The device comprises a base, a housing mounted in the middle of the upper end of the base, a fixed column fixedly connected to the middle portion between the upper and lower side walls of the housing, three sets of bosses welded equidistantly to the outer walls of the fixed column, each set of bosses comprising two bosses, and a guide sleeve rotatably connected to the fixed column between two of the bosses. The device operates by operating a hot air blower, causing hot air generated by the hot air blower to flow through an air guide pipe to an air outlet pipe, ultimately being ejected into the housing through a nozzle. A temperature sensor detects the temperature within the housing and transmits a signal to a PLC controller. When the temperature reaches a set value, the PLC controller controls the hot air blower to shut off. The temperature sensor continuously monitors the temperature within the housing. When the temperature within the housing drops to a minimum set value, the PLC controller controls the hot air blower to resume operation. This cycle provides a constant temperature environment for the Chinese cabbage seeds, resulting in efficient germination. The constant temperature equipment blows air from one side without penetrating air, which cannot improve the efficiency of constant temperature uniformity. Utility Model Content

[0004] The purpose of the utility model is to provide a constant temperature device for seed detection to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a constant temperature device for seed detection, comprising:

[0006] A constant temperature water bath pot provides constant temperature heating for the seeds to be tested, and a lid is connected to the top of the constant temperature water bath pot;

[0007] A rotating motor is fixedly connected to the top of the pot cover, and the output shaft of the rotating motor passes through the pot cover and is connected to a rotating rod. The outer periphery of the rotating rod is detachably connected to a plurality of limit ring plates arranged in parallel, and a blocking ring plate is provided on the outer periphery of the limit ring plate. A support net for supporting seeds and a support rod for improving stability are fixedly connected between the limit ring plate and the blocking ring plate;

[0008] Multiple vertical support plates arranged in a circular array are all connected to the bottom end of the pot cover. A fan is installed on the side of the vertical support plate. The top of the fan is connected to a ventilation hopper, and the ventilation hopper is connected to an inverted U-shaped ventilation pipe. The bottom end of the ventilation pipe is connected to an L-shaped exhaust pipe with one end as a closed structure. The exhaust pipe is provided with multiple inclined blowing channels on the side near the rotating rod.

[0009] As a preferred embodiment, the bottom end of the fan is detachably connected to a filter ring, the inner wall of the filter ring is connected to a filter screen, and the outer periphery of the rotating rod is connected to a cleaning brush for cleaning the filter screen.

[0010] As a preferred embodiment, the outer periphery of the rotating rod is further connected to a collecting bucket corresponding to the position of the cleaning brush.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are:

[0015] The constant temperature device for seed testing uses a constant temperature water bath to provide constant temperature heating, and a fan to blow air, which is then blown from multiple inclined blowing channels of the air release pipe, thereby blowing air from the upper and lower sides of the support net and the seeds on the support net. Compared with blowing air only from one side, the penetrating blowing from the lower side can improve the efficiency of uniform seed temperature.

The rotation of the rotating rod drives the cleaning brush to rotate in a circular motion, thereby cleaning the filter to avoid clogging. The collection bucket can collect the filtered matter to prevent it from falling onto the seeds on the top layer.

A support net 7 for supporting seeds and a support rod 8 for improving stability are fixedly connected between the limit ring plate 5 and the blocking ring plate 6. The rotating motor 3 drives the rotating rod 4 to rotate, indirectly driving the support net 7 and the seeds on the support net 7 to rotate, thereby improving the uniformity of the blowing.

[0034] A plurality of vertical support plates 9 arranged in a circular array are all connected to the bottom end of the pot cover 2. A fan 10 is installed on the side of the vertical support plate 9.

The bottom end of the ventilation pipe 12 is connected to an L-shaped exhaust pipe 13 with one end having a closed structure. The exhaust pipe 13 is provided with a plurality of inclined blowing channels on the side near the rotating rod 4. The constant temperature water bath 1 is heated, and the fan 10 blows air, and then blows air from the multiple inclined blowing channels of the exhaust pipe 13. The distance between the blocking ring plate 6 and the support net 7 is ensured to not excessively affect the blowing of the blowing channel, and then blows air to the support net 7 and the seeds on the support net 7 from the upper and lower sides, thereby improving the efficiency of uniform temperature of the seeds.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0038] How it works

[0039] The constant temperature device for seed testing evenly spreads seeds on the support net 7, controls the electric push rod 17 to retract, and finally places the pot cover 2 on the constant temperature water bath 1, which is then fixed with a lock. The constant temperature water bath 1, the rotating motor 3, and the fan 10 are turned on. The constant temperature water bath 1 is heated, and the fan 10 blows air, which is then blown from multiple obliquely arranged blowing channels of the air release pipe 13, and then blows air to the support net 7 and the seeds on the support net 7 from obliquely above and below, thereby improving the efficiency of uniform seed temperature.

[0040] When the fan 10 is blowing, the rotating motor 3 drives the rotating rod 4 to rotate, indirectly driving the support net 7 and the seeds on the support net 7 to rotate, thereby improving the uniformity of the blowing. During the ventilation process, the filter net of the filter ring 14 can filter the air to avoid clogging the fan 10. The rotation of the rotating rod 4 drives the cleaning brush 15 to rotate in a circle, thereby cleaning the filter net to avoid the filter net being blocked. The collecting bucket 16 can collect the filtered material to prevent it from falling and affecting the seeds on the top layer.
