Description

Technical Field

[0001] The invention relates to the technical field of rice seed storage, and in particular to a storage device for improving heat preservation and drying effects for planting rice seeds. Background Art

[0002] With the rapid development of social economy, the pace of life is getting faster and faster, and people's demand for quality of life is also increasing. Rice, as a necessity of life, enters the table every day. Nearly three-quarters of the world's population eats rice. At present, the germination operation commonly used by farmers is generally to drain the seeds after soaking them, tie them with bags with good heat preservation, and cover the seed bags with a small amount of covering to keep them warm when the temperature is low. Therefore, it is inconvenient to control the temperature and humidity of rice seed germination, which affects the germination effect of rice seeds. With the improvement of the degree of urban intensification, the cultivation of arable land has been concentrated on large-scale growers and cooperatives. The traditional farmer's soaking of seeds is no longer suitable for the development of modern agriculture. Rice seed germination urgently needs a storage device that improves the insulation and drying effect.

[0003] The prior art (application number 21922251111.0) discloses a storage device for rice seeds used in rice planting with improved heat preservation and drying effects. An air outlet hole connected to a stirring rod is provided at the lower end of a main rotating rod relative to a rotating sleeve. The airflow in the main rotating rod can enter the stirring rod which is also hollow and then contact the rice seeds, so as to achieve the effect of stirring the rice seeds while spraying hot air flow to heat the rice seeds, thereby greatly improving the uniform heating efficiency of the rice seeds. A slider engaged with a slide groove is provided on the outer side of the lower end of the main rotating rod relative to the rotating sleeve. When the main rotating rod drives the stirring rod to rotate through the rotating sleeve, the engaging block at the other end of the stirring rod can engage with the engaging groove. The engaging groove can be arranged in a circular wavy shape to drive the stirring rod and the rotating sleeve to move up and down during rotation.

[0004] Therefore, in the rice seed storage device, electric heating is used for drying, but in this process, the moisture generated after drying will be directly discharged and cannot be used, resulting in heat energy loss, which in turn increases the energy consumption of the device. Secondly, although the stirring method can promote air circulation, during the stirring process, the friction between the rice seeds and the friction between the rice seeds and the equipment will destroy the embryo of the rice seeds, reduce the seed germination rate, increase the amount of seeds purchased by farmers, and increase the investment cost. Therefore, the present invention proposes a storage device for planting rice seeds with improved heat preservation and drying effect to solve the problems existing in the prior art. Summary of the invention

[0005] In view of the above problems, the purpose of the present invention is to propose a storage device for planting rice seeds with improved heat preservation and drying effects. The storage device for planting rice seeds with improved heat preservation and drying effects has the advantages of high degree of mechanization, cost saving, efficiency improvement and energy saving. It adopts a static drying method to maintain the integrity of the rice seeds and can solve the problems existing in the prior art.

DETAILED DESCRIPTION

[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0022] For rice seeds, the embryo is the key part of germination. If the shell of the rice seed is damaged or the embryo is damaged, it will directly affect the germination ability. At the same time, the integrity of the rice seed helps prevent moisture from entering the seed and slow down the deterioration of the seed. Therefore, a dry and heat-insulating environment is required during the storage of rice seeds.

[0023] Therefore, according to Figure 1-Figure 5 As shown, this embodiment proposes a storage device for improving the heat preservation and drying effect of planting rice seeds, including a storage shell 1, a support base 18 is installed at the lower end of the storage shell 1, a groove is provided on the support base 18, and the groove is adapted to the bottom of the storage shell 1, a discharge port 19 is installed at the lower end of the storage shell 1, and two groups of discharge ports 19 are symmetrically provided, and an inner liner 2 is provided on the inner side of the storage shell 1. In this embodiment, the storage shell 1 and the inner liner 2 both have heat preservation performance.

[0024] An insulation chamber 3 is provided between the inner liner 2 and the storage shell 1. A hollow partition 4 is installed on the inner side of the inner liner 2. The hollow partition 4 divides the inner cavity of the inner liner 2 into two independent chambers, so that the device can store two different varieties of rice seeds.

[0025] An electric heating tube 5 is installed on the inner side of the hollow partition 4, and the electric heating tube 5 is provided in several groups. In the present embodiment, six groups of electric heating tubes 5 are evenly arranged. Contact tubes 6 are installed on both sides (left and right sides) of the hollow partition 4, and several groups of contact tubes 6 are provided. In the present embodiment, five groups of contact tubes 6 are provided on each side. The inner cavity of the contact tube 6 is connected to the hollow partition 4, and a ventilation assembly is installed on the contact tube 6.

[0026] like Figure 5 As shown, in the present device, the shape of the contact cylinder 6 is designed, and an inclined surface structure 10 is provided on the outer side of the contact cylinder 6. Air holes 11 are provided on the inclined surface structure 10, and the air holes 11 are evenly provided in a plurality of groups, that is, in the present device, part of the contact cylinder 6 is cylindrical and is used for installing the first fan 9, while the other part is provided with the inclined surface structure 10, and the lower end of the part is still arranged in an arc shape. When the rice seeds enter the inner cavity of the inner tank 2, they contact with the inclined surface structure 10 during the falling process, which can play a role of dividing the materials, so that the rice seeds are distributed more evenly during the falling process. At the same time, during the discharging process, it can avoid the accumulation of more rice seeds on the upper part of the contact cylinder 6.

[0027] Furthermore, the ventilation assembly includes a first fan 9, which is located on the inner side of the contact tube 6 and connected to the contact tube 6. The function of the first fan 9 is to transport the air in the hollow partition 4 to the contact tube 6 and discharge it upward through the air vent 11.

[0028] Therefore, when working, the rice seeds are loaded into the inner tank 2, the electric heating tube 5 is started, and the inner cavity of the hollow partition 4 is heated. Part of the heat contacts the rice seeds on the outside through the hollow partition 4, and the other part of the heat is discharged from the air vent 11 through the flow of air, and then contacts the rice seeds. At the same time, the contact tube 6 itself can also transfer heat after being heated, and then it can dry the rice seeds. When heat preservation is required, the power of the electric heating tube 5 is changed to achieve the effect of changing the heating temperature. In this embodiment, two groups of symmetrically arranged second temperature sensors 25 are installed on the inner side of the inner tank 2, and the second temperature sensors 25 sense the temperature of the inner cavity of the inner tank 2.

[0029] An air inlet cylinder 7 is installed above the storage shell 1. The air inlet cylinder 7 is connected to the hollow partition 4 through a processing assembly. The processing assembly includes an inner shell 12. The upper and lower ends of the inner shell 12 are connected to the storage shell 1 and the inner liner 2 respectively. Two groups of symmetrically arranged clamping plates 13 are arranged inside the inner shell 12. The clamping plates 13 are connected to the inner shell 12 through spring telescopic parts 14, and the spring telescopic parts 14 are provided with several groups. In this embodiment, each group of clamping plates 13 is correspondingly provided with four groups of spring telescopic parts 14. An air filter 15 is arranged between the two groups of clamping plates 13. In this embodiment, the air filter 15 adopts an insert-type design, and a socket is provided on the inner shell 12. The air filter 15 is inserted into the inner shell 12 by the staff, and then clamped by the clamping plate 13 and the spring telescopic parts 14. The air filter 15 has an input port and an output port, and an air filter inner core is arranged inside. External air enters through the air inlet cylinder 7, is filtered by the air filter 15, and then enters the hollow partition 4 for heating. The upper end of the hollow partition 4 is provided with ventilation holes on the inner liner 2, and the ventilation holes are evenly arranged in a plurality of groups for air circulation.

[0030] A feed port 16 is provided above the inner tank 2, and two groups of feed ports 16 are symmetrically provided. A feed pipe 17 is installed on the storage shell 1, and the number and position of the feed pipe 17 correspond to the feed port 16. The lower end of the feed pipe 17 passes through the feed port 16. During operation, the staff uses an external feeding device or a manual method to load the rice seeds to be stored from the feed pipe 17. After loading, the upper end of the feed pipe 17 is covered with a sealing cover. In this embodiment, a sealing cover is provided at the upper end of the feed pipe 17.

[0031] A three-way pipe 8 is installed at one end of the storage shell 1, and one end of the three-way pipe 8 is connected to the heat preservation chamber 3. A second fan 20 is installed above the inner tank 2 through a bracket. The second fan 20 plays a role in promoting air flow. The wind direction of the second fan 20 is toward the three-way pipe 8. An electric control valve and a first temperature sensor 21 are installed on the three-way pipe 8. Among them, the two ends of the three-way pipe 8 are respectively connected to the inner cavity of the storage shell 1 and the heat preservation chamber 3, and the remaining end plays a role in exhaust, and an electric control valve is provided on this end. At the beginning of work, the air in the inner tank 2 has not been fully heated. Therefore, in the process of air circulation, the air is first discharged through the three-way pipe 8, that is, in a stage of preheating, the cold air is first discharged. Then, after the preheating is completed, the electric control valve on the three-way pipe 8 is closed, and the air in the inner tank 2 enters the heat preservation chamber 3. The first temperature sensor 21 is used to monitor the temperature of the moisture during the circulation process.

[0032] The storage shell 1 is provided with an exhaust port 24 on one side away from the three-way pipe 8. The exhaust port 24 is connected to an external condenser through a pipeline, and the external condenser is connected to the air inlet cylinder 7 through a pipeline. During operation, the rice seeds will generate high-temperature moisture during the drying process, and the moisture needs to be discharged. However, in the present device, the moisture is introduced into the heat preservation chamber 3 during the discharge process, so the moisture will also release heat during the process of passing through the heat preservation chamber 3 to maintain the internal temperature of the device. In this process, the heat generated by the moisture is utilized, which can reduce the energy consumption of electric heating to a certain extent, and can also play a role of uniform heat preservation. However, an external condenser is provided, and the external condenser adopts an air exchange method to condense the moisture discharged from the present device. Then, in the process of condensation, it can play a role of secondary heat recovery, which is used to preheat the fresh air entering the device. Therefore, one output end of the external condenser is connected to the air inlet cylinder 7 through a pipeline, so the present device can make good use of the heat of the moisture and play a role of energy saving.

[0033] A water level probe 22 is installed on the storage shell 1, and one end of the water level probe 22 is located in the insulation chamber 3. A drain outlet 23 is installed at the lower end of the storage shell 1, and the position of the drain outlet 23 corresponds to the insulation chamber 3. A solenoid valve is also provided on the drain outlet 23. Its function is to avoid water accumulation in the insulation chamber 3. Therefore, a water level probe 22 is provided. When the water level probe 22 detects the water level, the solenoid valve on the drain outlet 23 opens to drain water.

[0034] The device has a total computer controller for controlling the working states of all electronic components of the device.
