Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting, in particular to a rice weed removal and seed selection device. Background Art

[0002] Rice refers to the seeds without removing the husk. Botanically, it belongs to the subspecies of Oryza sativa in the subgenus Oryza of the genus Oryza in the family Gramineae. Humans have identified 22 types of rice, but the only one used in bulk trade is Oryza sativa. my country is one of the countries with the longest history of rice cultivation and the richest rice genetic resources. Ancient cultivated rice specimens unearthed from the Yuchanyan site in Shouyan Town, Dao County, Hunan Province, confirm that China has a history of more than 14,000 years of rice cultivation, making it the known origin of cultivated rice in the world. Rice is one of the important food crops of mankind, and its history of cultivation and consumption is quite long. Half of the world's population eats rice, mainly in Asia, southern Europe, tropical America, and parts of Africa.

By arranging a water tank, a stirring mechanism, a blower, a second air supply pipe, a second sieve plate, a water inlet pipe, a water outlet, a filter box, a water pump, a return pipe, a discharge port, and a drain port, the device can stir and blow air to make the shriveled seeds quickly float to the surface of the water and enter the filter box with the water flow for collection, thereby improving the seed selection efficiency. The filtered water in the filter box enters the water tank through the return pipe, which is convenient for recycling the water. The fine sand and gravel in the seeds enter the bottom of the water tank through the second sieve plate and are then discharged through the drain pipe, thereby improving the quality of the rice seeds.

[0004] When the above-mentioned device is in use, although the dry seeds in the rice can be screened through the water tank and the stirring mechanism, the above-mentioned method of use requires the seeds to be placed in water for screening.

The normal operation and maintenance of the seed selection device, including power supply The seed selection device should be equipped with safety protection devices, including emergency stop buttons, protective covers, etc., to ensure the safety of operators and equipment. Operators need to wear appropriate work clothes and protective gear, such as gloves and masks, to prevent injuries and contamination caused by careless operation.

[0026] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a rice impurity removal and seed selection device, comprising a seed selection box 1 and a support leg 103 installed at the bottom end of the seed selection box 1, an integrally formed connecting platform is installed on the outer front side of the seed selection box 1, a feed hopper 101 is installed on the top of the seed selection box 1, an impurity removal structure 2 is installed between the inner walls of the top end of the seed selection box 1, and a seed selection mechanism 3 is installed between the inner walls of the bottom end of the seed selection box 1;

[0027] The impurity removal structure 2 is used to clean the impurities in the rice, and the seed selection mechanism 3 is used to screen the rice seeds. A mounting hole is provided on the outer wall of one end of the seed selection box 1, and an impurity discharge pipe 102 is installed in the mounting hole. A discharge hole 105 is provided at the bottom of the seed selection box 1.

[0028] The impurity removal structure 2 includes:

[0029] A rotating shaft 201 is rotatably installed between the inner walls of the seed selection box 1, and a fan blade 202 is installed on the outer wall of the rotating shaft 201. A motor 206 is installed on the outer side of one end of the seed selection box 1. The output end of the motor 206 passes through the inner side of one end of the seed selection box 1 and is fixedly connected to one end of the rotating shaft 201.

[0030] The inner walls at both ends of the seed selection box 1 are installed with an integrally formed inclined plate, a discharge hole is opened at the bottom of the inclined plate, a discharge hopper 203 is installed in the discharge hole, a baffle 204 is movably provided at the bottom of the discharge hopper 203, and a rotating shaft 205 is installed at one end of the baffle 204.

[0031] Both ends of the rotating shaft 205 are rotatably connected to the inner wall of the seed selection box 1, and a support rod 207 is installed at one end of the rotating shaft 205. The support rod 207 is located on the outside of the front of the seed selection box 1, and a counterweight block 208 is movably installed on the support rod 207 near the top outer wall.

[0032] It should be noted that if Figure 2 The whole device needs to be connected to an external power source. The impurity removal structure 2 in the seed selection box 1 is located on one side of the seed selection box 1 and on the lower side of the feed hopper 101. When the seeds need to be impurity-removed, the whole device is first powered on, and then the motor 206 drives the rotating shaft 201 to rotate. Because a plurality of fan blades 202 are installed on the outer wall of the rotating shaft 201, the rotating fan blades 202 can generate air volume on the upper part of the seed selection box 1, and then the seeds that need to be impurity-removed are passed through the feed hopper 101 into the seed selection box 1. Because the fan blades 202 are constantly rotating, the air volume can be generated by the fan blades 202. The hopper 203 is provided with a baffle plate 204 at the bottom to block the seeds after the impurities are removed, and the baffle plate 204 is connected with a rotatable shaft 205. When the weight of the seeds exceeds the counterweight block 208 on the support rod 207, the seeds will fall into the seed selection mechanism 3 at the bottom to screen the seeds.

[0033] Seed selection agency 3 includes:

[0035] A connecting seat 303 is installed on the outer wall of the screening box 302 , a connecting rod 304 is installed on the inner wall of the connecting seat 303 through bolts, and a supporting seat 306 is installed on the outer wall of the connecting rod 304 .

[0036] A rotating rod 309 is rotatably connected between the outer sides of the support seat 306, and cams 308 are installed on the outer walls of both ends of the rotating rod 309. A mounting hole is opened on the outer side of one end of the connecting rod 304, and a fixed rod 305 is fixedly connected in the mounting hole. A connecting shaft 307 is installed on the outer wall of the cam 308, and the other end of the connecting shaft 307 is connected to the outer wall of the fixed rod 305.

[0037] It should be noted that if Figure 1As described, when the seeds after impurity removal fall into the screening box 302, because the screening box 302 is connected to the slide rail 301 through a slider, and the slide rail 301 is an electric slide rail, the screening box 302 can be moved, and the moving screening box 302 will screen the seeds and discharge them through the discharge hole 105 at the bottom, and the connecting seat 303 on the outer wall of the screening box 302 is connected to the connecting rod 304 through bolts, and the screening box 302 can be replaced according to different seeds. While the screening box 302 is moving, the cam 308 connected by the connecting shaft 307 can be driven to rotate by the fixing rod 305 on the connecting rod 304, so that the screening box 302 can form a reciprocating motion. The setting of the seed selection mechanism 3 does not require a large amount of soaking of seeds, saves the use of water resources, and avoids the situation where the seeds are not planted in time and germinate. The screening box 302 can be set according to the size, shape and density of the seeds for accurate screening, ensuring that the selected seeds are of good quality, which is conducive to improving the planting value and yield of the seeds.
