Description

Technical Field

[0001] Generally speaking, the present invention relates to the technical field of agricultural product production. Specifically, it relates to an insect removal device for storing and transporting rice. Background Art

[0002] Rice weevils are insects of the genus Sitophilus in the family Curculionidae of Coleoptera. When newly emerged, they are reddish-brown, and after a period of time, the brown color deepens; the elytra have markings; the head of the larva is oval and relatively wide; the abdomen of the pre-pupa is not as straight and uncurved as that of the maize weevil, the pupa is smaller than that of the maize weevil, the body is slender, and the hind wings are shorter. The adult lifespan is about 7 - 8 months, and can reach up to 2 years at most. Rice weevils are distributed worldwide, and in China, they are mainly distributed in the southern provinces and autonomous regions. They like to eat grain kernels, produce water during metabolism, and do not "drink water" throughout their lives. They enter a state of suspended animation at low temperatures and resume activity after the normal body temperature is restored. They overwinter as adults in the granary, and the optimum development temperature is 26 - 31 degrees Celsius. Rice weevils are one of the important storage pests, mainly damaging the old grain stored for 2 - 3 years. They have strong reproductive ability and large food consumption, thus causing huge losses to the storage of grain.

[0003] In the prior art, the main method for controlling rice weevils is to fumigate rice with fumigants, and phosphine is the fumigant most widely used, with the widest range and the longest time in China. The mechanism by which phosphine fumigation can kill insects is generally considered that phosphine enters the pest body in the presence of oxygen and is oxidized to form other substances, and the oxidation is irreversible. This substance acts on the target site of the pest. Scholars generally believe that at this site, the oxidation product of phosphine reacts with the enzymes present at this position, such as cytochrome oxidase, catalase, P450 enzyme, etc., thus causing the pest body to malfunction and leading to its death. However, due to the long-term use of fumigants, rice weevils have begun to develop selective resistance, and the emergence of resistance has made the control of rice weevils another major problem in grain storage. Summary of the Invention

[0004] This application provides an insect removal device for storing and transporting rice to solve the technical problem of huge losses caused by the large-scale reproduction of rice weevils in the storage and transportation of rice.

[0005] This application provides an insect removal device for storing and transporting rice, including: a barrel body, a guide cylinder, a rotating blade, a cooler, and a sieve plate; the guide cylinder is arranged at the center of the barrel body; the rotating blade is rotatably arranged inside the guide cylinder; the cooler is connected to the guide cylinder and cools the guide cylinder; the sieve plate is arranged below the guide cylinder.

[0006] Furthermore, a plurality of connecting rods are arranged between the guide cylinder and the barrel body.

[0007] Furthermore, the size of the blade of the rotating blade matches the inner diameter of the guide cylinder, and the length of the rotating blade in the axial direction is greater than the height of the guide cylinder.

[0008] Further, the rotating blade is driven by a rotation driving member, and the rotation driving member is arranged at the top of the barrel body.

[0009] Further, the cooler adopts a compression refrigerating machine. The body of the compression refrigerating machine is arranged outside the barrel body, and the heat absorption pipe of the compression refrigerating machine is connected to the guide cylinder.

[0010] Further, the heat absorption pipe is wound around the outer wall of the guide cylinder in a ring shape.

[0011] Further, the sieve plate is detachably connected to the barrel body.

[0012] Further, a feed port is formed in one side of the top of the barrel body, and a discharge port is arranged at the bottom of the barrel body.

[0013] Further, a heat preservation material is arranged on the outer wall of the barrel body.

[0014] As can be seen from the above technical solutions, the advantages and positive effects of an insect removal device for rice storage and transportation according to the present invention are as follows: The rotating blade rotates in the guide cylinder to transport the rice from the bottom of the barrel body to the top of the barrel body, forming a reverse flow inside and outside the guide cylinder, so that the rice forms a cycle in the barrel body. The cooler cools the guide cylinder, and the rice continuously exchanges heat with the guide cylinder during the cycle. At this time, the rice weevils mixed in the rice will enter a state of suspended animation due to the low temperature, thus losing their mobility, curling up their limbs, losing their attachment to the rice, and falling through the sieve holes below the sieve plate, realizing the separation from the rice. Compared with the traditional method of fumigating rice with fumigants for insect removal, it will not only cause the rice weevils to develop drug resistance, but also be safer and more environmentally friendly, without polluting the environment, and solves the technical problem of huge losses caused by the large reproduction of rice weevils to rice storage and transportation.

[0026] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and devices should be regarded as part of the specification.

[0027] As Figure 1 and Figure 2 shown, an insect-removing device for storing and transporting rice in an embodiment includes: a barrel body 1, a diversion cylinder 2, a rotating blade 3, a cooler 4, and a sieve plate 5. The diversion cylinder 2 is arranged at the center of the barrel body 1. The rotating blade 3 is rotatably arranged in the diversion cylinder 2. The cooler 4 is connected to the diversion cylinder 2 and cools the diversion cylinder 2. The sieve plate 5 is arranged below the diversion cylinder 2. By rotating the rotating blade 3 in the diversion cylinder 2, the rice is transported from the bottom of the barrel body 1 to the top of the barrel body 1. After a vacancy is formed at the bottom of the diversion cylinder 2, the rice outside the diversion cylinder 2 will collapse downward for replenishment, so that a reverse flow is formed inside and outside the diversion cylinder 2, and the rice forms a cycle in the barrel body 1. The cooler 4 cools the diversion cylinder 2, and the rice continuously exchanges heat with the diversion cylinder 2 during the cycle. At this time, the rice weevils mixed in the rice will enter a state of suspended animation due to the low temperature, thus losing their mobility, curling up their limbs, losing their attachment to the rice, and falling through the sieve holes below the sieve plate 5, realizing the separation from the rice. Compared with the traditional method of fumigating rice with fumigants, it not only does not cause the rice weevils to develop drug resistance, but also is safer and more environmentally friendly, does not pollute the environment, and solves the technical problem of huge losses caused by the large reproduction of rice weevils to the storage and transportation of rice.

[0028] As Figure 1 and Figure 2 shown, in the technical solution of Embodiment 1, a plurality of connecting rods 6 are arranged between the diversion cylinder 2 and the barrel body 1. The connecting rods 6 are used to keep the diversion cylinder 2 at the center of the barrel body 1, playing a role in fixing the diversion cylinder 2. The connecting rods 6 have a relatively small obstructive effect on the flow of rice in the barrel body 1, which can generally be ignored.

[0029] As Figure 1 and Figure 2As shown, in the technical solution of the first embodiment, the blade size of the rotating blade 3 matches the inner diameter of the guide cylinder 2, and the axial length of the rotating blade 3 is greater than the height of the guide cylinder 2. The blade size of the rotating blade 3 matches the inner diameter of the guide cylinder 2, that is, the gap between the rotating blade 3 and the inner wall of the guide cylinder 2 is small, which can better realize the unidirectional transportation of rice from bottom to top. The axial length of the rotating blade 3 is greater than the height of the guide cylinder 2, that is, the bottom of the rotating blade 3 extends out of the guide cylinder 2, which can be transported from the bottom to avoid the formation of a stagnation area.

[0030] like Figure 1 and Figure 2 As shown, in the technical solution of the first embodiment, the rotating blade 3 is driven by a rotating driving member, and the rotating driving member is arranged on the top of the barrel body 1. Since the rotating blade 3 does not need an excessively high rotation speed and the operating load is large, the rotating driving member can use a reduction motor 7, which refers to an integrated body of a reducer and a motor 7 (motor). This integrated body is also generally referred to as a gear motor or a gear motor 7, which is integrated and assembled by a professional reducer manufacturer and supplied as a set. The advantage of using a reduction motor 7 is that it simplifies the design and saves space.

[0031] like Figure 1 and Figure 2 As shown, in the technical solution of embodiment 1, the refrigerator 4 adopts a compression refrigerator, the main body of the compression refrigerator is arranged outside the barrel 1, and the heat absorption pipe 40 of the compression refrigerator is connected to the guide tube 2. The compression refrigerator relies on a compressor to increase the pressure of the refrigerant to realize the refrigeration cycle. The refrigerator consists of a compressor, a condenser (condenser), a refrigeration heat exchanger (evaporator), an expander or a throttling mechanism and some auxiliary equipment. According to the type of refrigerant used, it can be divided into two categories: gas compression refrigerator and vapor compression refrigerator. A refrigerator that relies on a compressor to increase the pressure of the refrigerant to realize the refrigeration cycle. Classification: According to the type of refrigerant used, compression refrigerators are divided into gas compression refrigerators and vapor compression refrigerators. Vapor compression refrigerators include ammonia refrigerators and Freon refrigerators. Gas compression refrigerators are divided into air refrigerators and helium refrigerators. According to the type of compressor used, compression refrigerators are divided into reciprocating refrigerators, centrifugal refrigerators and rotary refrigerators (screw refrigerators, rolling rotor refrigerators), etc. Steam compression refrigerators are divided into single-stage, multi-stage (two-stage or three-stage) and cascade types according to their system composition.

[0032] like Figure 1 and Figure 2As shown, in the technical solution of the first embodiment, the heat absorption tube 40 is wound around the outer wall of the flow guide cylinder 2 in a ring shape. By winding the heat absorption tube 40 around the outer wall of the flow guide cylinder 2, the heat absorption tube 40 can fully exchange heat with the flow guide cylinder 2, and the heat is taken out of the barrel body 1 through the heat absorption tube 40, so that the overall temperature of the barrel body 1 is reduced.

[0033] As Figure 1 and Figure 2 As shown, in the technical solution of the first embodiment, the sieve plate 5 is detachably connected to the barrel body 1. The cross-sectional shape of the barrel body 1 is different from that of the flow guide cylinder 2. The cross-sectional shape of the flow guide cylinder 2 is circular, and the cross-sectional shape of the barrel body 1 is square. Therefore, the shape of the sieve plate 5 is also square. An installation opening is provided on one side of the barrel body 1, and the sieve plate 5 can be pulled and installed through the installation opening. A limiting plate for supporting the sieve plate 5 is also provided on the barrel body 1. A number of sieve holes are provided on the sieve plate 5 for sieving rice weevils. The diameter of the sieve holes is smaller than the diameter of the rice grains but larger than the outer contour length of the rice weevils. A handle is provided at one end of the sieve plate 5 to facilitate the pulling of the sieve plate 5. When the sieve plate 5 is pulled out, the rice can flow out from the bottom of the barrel body 1, facilitating unloading.

[0034] As Figure 1 As shown, in the technical solution of the first embodiment, a feed inlet 10 is provided on one side of the top of the barrel body 1, and a discharge outlet 11 is provided at the bottom of the barrel body 1. The feed inlet 10 is a single-sided inclined hopper, which facilitates the entry of rice into the feed inlet 10. The discharge outlet 11 is a conical funnel. During use, the falling rice weevils slide down along the conical surface to the bottom and are discharged from the barrel body 1. When unloading, a container or a sack can be used to collect the rice at the discharge outlet 11.

[0035] As Figure 1 and Figure 2 As shown, in the technical solution of the first embodiment, a heat-insulating material is provided on the outer wall of the barrel body 1. The heat-insulating material generally refers to a material with a thermal coefficient less than or equal to 0.12. Traditional heat-insulating materials mainly improve the gas-phase void ratio and reduce the thermal conductivity and conduction coefficient. For fibrous heat-insulating materials, in order to increase the convective heat transfer and radiative heat transfer in the use environment, a relatively thick coating must be provided; while profile inorganic heat-insulating materials need to be assembled and constructed, which have defects such as many joints, poor aesthetics, poor waterproof performance, and short service life. The application of the heat-insulating material can reduce the influence of the ambient temperature on the temperature inside the barrel body 1 and reduce the use energy consumption.
