Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, and in particular to a soybean metering and conveying device and a metering and conveying method. Background Art

[0002] Soybean, a plant of the genus Glycine max in the family Leguminosae, is 30-90 cm tall, with a sturdy, upright stem densely covered with long brown stiff hairs, leaves usually with 3 leaflets, stipules with veins, covered with yellow soft hairs, and petioles 2-20 cm long. The peduncle usually has 5-8 sessile, tightly packed flowers, lanceolate calyx, and purple, lavender or white flowers. The pods are large, slightly curved, drooping, yellow-green, densely covered with brown-yellow long hairs; there are 2-5 seeds, which are elliptical or nearly spherical.

[0003] According to Chinese patent CN215665502U, a dry spiral conveying device for defatted soybean meal processing is proposed. The device can convey soybeans forward by arranging a second spiral blade, spread the soybeans and disperse them by arranging a first spiral blade, and blow air into the soybeans in transportation by arranging a hollow shaft with air holes, which can not only dry the soybeans, but also blow the seed coats in the soybeans out of the movable net cylinder, thereby achieving the purpose of drying and removing impurities.

[0004] The soybean conveying device in the prior art has some shortcomings. In the process of conveying soybeans, since some fine impurities are easily mixed in the soybeans, the soybeans are easily mixed with the impurities when the device conveys the soybeans. The impurities need to be screened by manpower after the soybeans are transported to filter out the impurities. The process consumes a lot of time and energy, affecting the conveying effect of the soybeans. For this reason, we propose a soybean metering and conveying device and a metering and conveying method.

[0037] A preferred embodiment of a soybean metering and conveying device provided by the present invention is as follows: Figures 1 to 9As shown: a conveying assembly 33 is arranged on the top of the mounting plate 1, and the conveying assembly 33 includes a cross frame 331 fixedly connected to the top of the mounting plate 1, and the outer wall of the cross frame 331 is fixedly connected to the third motor 332, and the output end of the third motor 332 is fixedly connected to a driving shaft 333, and the driving shaft 333 movably penetrates the outer wall of the cross frame 331 and extends to the inside of the cross frame 331, and the outer wall of the other end of the driving shaft 333 is rotatably connected to the inner wall of the cross frame 331 through a bearing, and the outer wall of the driving shaft 333 is slidably connected to a conveyor belt 334, and the inner wall of the other end of the conveyor belt 334 is slidably connected to a driven shaft 335, and the end surface of the driven shaft 335 The outer wall is rotatably connected to the inner wall of the cross frame 331 through a bearing, and the conveyor belt 334 is located below the drop plate 328. By setting the conveying assembly 33, after the soybeans are metered, when the soybeans need to be conveyed, the operator can open the cross block 3210 and the second baffle 3211 to cause the soybeans to fall on the surface of the conveyor belt 334. Then, the operator turns on the third motor 332 to cause the driving shaft 333 to rotate.

[0039] In addition, the outer wall of one end of the slider 319 is slidably matched with the inner wall of the limiting groove 317 , and the inner wall of the slider 319 is slidably connected with the outer wall of the limiting rod 318 .

[0040] A method for measuring and conveying soybeans, comprising the following steps:

[0041] S1. First, the impurities in the soybeans are screened by the screening plate 3111;

[0042] S2, secondly, the screened soybeans are transferred to the inside of the blanking plate 328 through the guide plate 3120;

[0043] S3, then measure the soybeans through the metering device body 3212 at the bottom of the blanking plate 328;

[0044] S4. Finally, the measured soybeans are transported by the conveyor belt 334.

[0045] Working principle: In the process of conveying soybeans, in order to prevent soybeans from being mixed with impurities, the soybeans need to be screened. At this time, the operator can place the soybeans on the bottom of the inner wall of the screening plate 3111, and then turn on the first motor 314 to cause the output shaft 315 to rotate. During the rotation of the output shaft 315, the cam 316 will rotate. During the rotation of the cam 316, the screening plate 3111 will be squeezed. The screening plate 3111 will move downward along the outer wall of the limit rod 318 through the slider 319 and compress the spring 3110. When the cam 316 rotates upward and does not compress the screening plate 3111, the slider 319 and the screening plate 3111 will bounce upward under the reaction of the spring 3110, so that the screening plate 3111 will vibrate up and down, thereby effectively screening the soybeans and impurities inside the screening plate 3111.

During the movement of the L-shaped plate 3118, the extrusion block 3119 will be moved with it, prompting the extrusion block 3119 to hit the outer wall of the screening box 312, thereby preventing the sieved soybeans inside the screening box 312 from accumulating. During the movement of the rack 3113, the cleaning brush 3114 will also be moved with it, prompting the cleaning brush 3114 to brush the impurities on the inner wall of the screening plate 3111, thereby preventing the impurities from accumulating and affecting the screening effect of the soybeans. After the soybeans are screened, the soybeans will fall on the surface of the guide plate 3120.

[0046] After the soybeans are on the surface of the guide plate 3120, in order to measure the soybeans, the operator can start the double-headed motor 323 to cause the double-headed motor 323 to rotate with the screw rod 324. During the rotation of the screw rod 324, the sleeve block 325 will move, causing the sleeve block 325 to move laterally with the baffle plate 327, so that the soybeans pass through the discharge chute 321 and fall into the inside of the blanking plate 328. Then, the metering device body 3212 is started to measure the soybeans, and the soybeans in the measuring process are blocked by the vertical block 329, the horizontal block 3210 and the second baffle plate 3211.

[0047] After the soybeans are metered, when they need to be transported, the operator can open the horizontal block 3210 and the second baffle 3211 to cause them to fall on the surface of the conveyor belt 334. Then, the operator turns on the third motor 332 to cause the driving shaft 333 to rotate. The rotation of the driving shaft 333 will drive the conveyor belt 334 and cause the driven shaft 335 to rotate, thereby transporting the soybeans on its surface through the conveyor belt 334 during the transmission process.
