Technical Field

[0001] The utility model relates to the technical field of seeds, in particular to a moisture sampling and inspection device for vegetable seeds. Background Technique

[0002] There are a wide variety of vegetables, and the corresponding vegetable seeds also have their own characteristics, with different shapes, sizes, colors, etc. For example, cucumber seeds are flat and slender, while tomato seeds are smaller and yellow;

[0003] In order to ensure the germination rate of vegetable seeds, during their production process, a seed moisture tester is regularly used to conduct moisture sampling and inspection on a part of the vegetable seeds. The seed moisture tester usually adopts the principle of drying and weight loss method. Specifically, this device heats and dries a certain amount of vegetable seeds to evaporate the moisture in the seeds, and then measures the weight change of the seeds before and after drying. According to the ratio of the weight loss to the weight of the seeds before drying, the moisture content of the seeds is calculated. And such a device for conducting moisture sampling and inspection on vegetable seeds can be called a moisture sampling and inspection device for vegetable seeds.

[0004] However, when using such a moisture sampling and inspection device for vegetable seeds to conduct moisture detection on some vegetable seeds with larger volumes, such as cucumber seeds and pumpkin seeds, due to the larger volumes of these vegetable seeds, it takes a longer time to completely dry them, and the detection efficiency of this device for larger seeds is relatively low; therefore, it does not meet the existing requirements, and for this reason, we propose a moisture sampling and inspection device for vegetable seeds. Content of the Utility Model

[0005] The purpose of the utility model is to provide a moisture sampling and inspection device for vegetable seeds to solve the problems mentioned in the above background technique, that is, when using such a moisture sampling and inspection device for vegetable seeds to conduct moisture detection on some vegetable seeds with larger volumes, such as cucumber seeds and pumpkin seeds, due to the larger volumes of these vegetable seeds, it takes a longer time to completely dry them, and the detection efficiency of this device for larger seeds is relatively low.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A moisture sampling and inspection device for vegetable seeds, including a seed moisture tester. On one side of the upper end surface of the seed moisture tester, there is a drying tank. Inside the drying tank, there is a seed placement spoon. On one side of the upper end surface of the seed placement spoon, there is a strip-shaped placement groove. Inside the upper side of the strip-shaped placement groove, there is a fixed seed placement net. The outer surface of the seed placement net is provided with a plurality of through holes, and both the seed placement net and the strip-shaped placement groove are strip-shaped;

[0007] Above each of the through holes, an insertion needle is provided. On one side of the bottom end of each insertion needle, a circular through hole is provided, and the upper end surfaces of a plurality of the insertion needles are connected to a cyclic up-and-down movement mechanism.

[0008] Preferably, one side of the drying tank is provided with a control panel located on the outer surface of the seed moisture tester.

[0009] At the middle position of the lower end surface of the seed placement spoon, a square groove is provided. Inside the square groove, a square head is provided, the lower end surface of which is fixed to the inner wall of the drying tank. The cross-sectional shape of the inner wall of the square groove is square. The outer surface of the square head fits with the inner wall of the square groove, and the square groove and the square head are slidably connected.

[0010] Preferably, above the drying tank, a sealing cap is installed on the upper end surface of the seed moisture tester through a rotating shaft, and all the insertion needles and the cyclic up-and-down movement mechanism are located inside the sealing cap.

[0011] Preferably, the cyclic up-and-down movement mechanism includes a stepping motor. The output shaft of the stepping motor is connected to a concave rotating shaft through a coupling. The shape of the middle position of the outer surface of the concave rotating shaft is concave, and a metal sleeve is movably sleeved on the concave part of the outer surface of the concave rotating shaft.

[0012] Preferably, a plurality of connecting rods with the same number and corresponding positions as the insertion needles are fixed to the lower end surface of the metal sleeve.

[0013] Preferably, a guide sleeve is provided below the metal sleeve, and all the rotating shaft connecting rods vertically pass through the guide sleeve movably.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. When this device is needed to detect some seeds with larger volumes, place the seeds on the upper end surface of the seed placement net. Then, through the cyclic up-and-down movement mechanism, all the insertion needles can be cyclically moved up and down synchronously. When the insertion needles move downward, they will contact the seeds placed on the upper end surface of the seed placement net and penetrate them, thereby punching a plurality of pinholes on the outer surface of the seeds. Through these pinholes, the surface area of the seeds can be increased. A larger surface area means an increased contact area with hot air, enabling more channels and outlets for moisture to evaporate. Through the above technical solution, the speed of moisture diffusion from the inside of the seeds to the outside can be accelerated, thereby improving the evaporation efficiency of moisture, reducing the time required to dry the seeds, and improving the detection efficiency of the device for larger seeds.

Specific implementation manner

[0020] 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 the embodiments.

[0021] The seed moisture tester 1 (model XF-110MA), stepping motor 4 (model 450A) and inserting needle 8 (model LSSDZ-18) mentioned in the present utility model can all be obtained by purchasing from the market or customizing privately.

[0022] Please refer to Figures 1 to 3 , an embodiment provided by the present utility model: A moisture sampling device for vegetable seeds, including a seed moisture tester 1. One side of the upper end surface of the seed moisture tester 1 is provided with a drying tank 2. Inside the drying tank 2 is provided a seed placing spoon 3. One side of the upper end surface of the seed placing spoon 3 is provided with a strip placing groove 17. The upper side inside the strip placing groove 17 is fixedly provided with a seed placing net 13. The outer surface of the seed placing net 13 is provided with a plurality of through holes 14, and both the seed placing net 13 and the strip placing groove 17 are strip-shaped;

[0023] Above each through hole 14 is provided an inserting needle 8. One side of the bottom end of each inserting needle 8 is provided with a circular through hole 10, and the upper end surfaces of a plurality of inserting needles 8 are connected with a cyclic up-and-down moving mechanism.

[0024] One side of the drying tank 2 is provided with a control panel 15 on the outer surface of the seed moisture tester 1; The device can be controlled through the control panel 15.

[0025] A square groove 12 is provided at the middle position of the lower end surface of the seed placing spoon 3. Inside the square groove 12, there is a square head 11 whose lower end surface is fixed to the inner wall of the drying groove 2. The cross-sectional shape of the inner wall of the square groove 12 is square. The outer surface of the square head 11 fits with the inner wall of the square groove 12, and the square groove 12 is slidably connected to the square head 11. When this device is needed to detect some seeds with larger volumes, place the seeds on the seed placing net 13 in the placing groove 17 on the upper end surface of the seed placing spoon 3. Then align the square groove 12 at the lower end surface of the seed placing spoon 3 with the square head 11 inside the drying groove 2. After that, place the seed placing spoon 3 inside the drying groove 2 until the lower end surface of the seed placing spoon 3 touches the inner wall of the drying groove 2. Through the square head 11 and the square groove 12, the through holes 14 on the outer surface of the seed placing net 13 can be aligned with the piercing needles 8.

[0026] Above the drying groove 2, there is a sealing cap 16 installed on the upper end surface of the seed moisture tester 1 through a rotating shaft, and all the piercing needles 8 and the cyclic up-and-down moving mechanism are located inside the sealing cap 16. After the seed placing spoon 3 is placed, cover the sealing cap 16 and start the device for drying operation.

[0027] The cyclic up-and-down moving mechanism includes a stepping motor 4. The output shaft of the stepping motor 4 is connected to a concave rotating shaft 5 through a coupling. The shape of the middle position on the outer surface of the concave rotating shaft 5 is concave. A metal sleeve 6 is movably sleeved on the concave part of the outer surface of the concave rotating shaft 5. After the sealing cap 16 is covered, start the stepping motor 4. The stepping motor 4 can drive the connected concave rotating shaft 5 to rotate. When the concave rotating shaft 5 rotates, the metal sleeve 6 sleeved on the concave part of the outer surface of the concave rotating shaft 5 will revolve around the front end of the metal sleeve 6.

[0028] A plurality of connecting rods 7 with the same number and corresponding positions as the piercing needles 8 are fixed to the lower end surface of the metal sleeve 6. The lower end surface of the connecting rod 7 is connected to a rotating shaft connecting rod 18 through a rotating shaft. The lower end surface of the rotating shaft connecting rod 18 is fixed to the piercing needle 8 below it. Below the metal sleeve 6, there is a guiding sleeve 9. All the rotating shaft connecting rods 18 vertically pass through the guiding sleeve 9 movably. During the revolution of the metal sleeve 6, it will pull the connecting rods 7 connected to its lower end surface and the rotating shaft connecting rods 18 connected to the lower end surfaces of the connecting rods 7 to move up and down cyclically. And through the guiding sleeve 9, it can ensure that the vertically moving rotating shaft connecting rods 18 remain in an upright state. When the rotating shaft connecting rods 18 move up and down, the piercing needles 8 fixed to their lower end surfaces will move up and down accordingly. When the piercing needles 8 move downward, they will contact the seeds placed on the upper end surface of the seed placing net 13 and penetrate them. And through the through holes 14 on the upper end surface of the seed placing net 13, the situation that the piercing needles 8 directly contact the seed placing net 13 can be prevented.

[0029] After the seeds are penetrated by the piercing needle 8, as the piercing needle 8 ascends, the seeds penetrated by the piercing needle 8 will move upward together. The upward-moving seeds will come into contact with the circular through-hole 10. Through the circular through-hole 10, the seeds located on the outer surface of the piercing needle 8 can be pushed down. The pushed-down seeds will fall again onto the upper surface of the seed placement net 13, and at this time, a needle hole penetrated by the piercing needle 8 will appear on the outer surface of the seeds. Through this needle hole, the surface area of the seeds can be increased. A larger surface area means an increased contact area with hot air, enabling more channels and outlets for moisture to evaporate. Through the above technical solution, the speed of moisture diffusion from the inside of the seeds to the outside can be accelerated, thereby improving the evaporation efficiency of moisture, reducing the time required for drying the seeds, and improving the detection efficiency of the equipment for larger seeds;

[0030] When the piercing needle 8 moves up and down five times and multiple needle holes are penetrated on the outer surfaces of all the seeds, the stepper motor 4 is turned off, and then wait for the seeds to be completely dried, and the moisture inside the seeds can be calculated based on the data.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
