Description

Technical Field

[0001] The present invention relates to an automatic rice vending machine, and particularly to a grain transportation device. Background Art

[0002] At present, the automatic rice vending machines on the market generally set the grain bin at the lower part inside the machine. The grains in the grain bin are transported upward to a temporary storage bin located at the upper part inside the machine through a screw-type lifting device, and then the grains are sent from the temporary storage bin to a rice milling device located below the temporary storage bin for rice milling. In order to control the feeding amount from the temporary storage bin to the rice milling device, a photoelectric sensor is arranged in the temporary storage bin. The photoelectric sensor senses the grain amount in the temporary storage bin to control whether the screw-type lifting device continues to feed grains into the temporary storage bin. When the grains fall from the screw-type lifting device into the temporary storage bin, the grains will accumulate on one side of the temporary storage bin, resulting in inaccurate sensing of the grain amount by the photoelectric sensor and inability to accurately control the start and stop time of feeding of the screw-type lifting device. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] As Figure 1 and Figure 3As shown in the figure, a grain transportation device includes a temporary storage bin 100, a sensor 200, a material guiding channel 300, and a feeding assembly. The bottom of the temporary storage bin 100 can be funnel-shaped, with a discharge opening 120 provided at the bottom. The discharge opening 120 is communicated with the rice milling device in the automatic rice vending machine. An inlet opening 110 is provided on the upper side wall of the temporary storage bin 100. The inlet opening 110 is communicated with the screw type lifting device 500 of the automatic rice vending machine. The screw type lifting device 500 lifts and transports the grains from the bottom bin of the automatic rice vending machine to the inlet opening 110. The sensor 200 can be an optoelectronic sensor 200. The sensor 200 is placed in the temporary storage bin 100 to sense the accumulated height of the grains entering the temporary storage bin 100. At the same time, the sensor 200 is connected to the screw type lifting device 500 to control the start and stop of the screw type lifting device 500. The material guiding channel 300 can be in the shape of a straight cylinder, etc., and is installed across in the temporary storage bin 100. The height where the material guiding channel 300 is located is higher than the height where the sensor 200 is located. A material dropping opening 310 is provided on the material guiding channel 300. The material dropping opening 310 is located above the discharge opening 120. One end of the material guiding channel 300 is connected to the inlet opening 110. The grains transported by the screw type lifting device 500 fall into the material guiding channel 300 through the inlet opening 110. The feeding assembly includes a guiding screw 410 and a motor 420. The motor 420 can be installed outside the temporary storage bin 100. The guiding screw 410 is installed in the material guiding channel 300. One end of the guiding screw 410 extends out of the temporary storage bin 100 and is connected to the motor 420. The motor 420 drives the guiding screw 410 to rotate. During the rotation of the guiding screw 410, the grains are transported from one end of the material guiding channel 300 close to the inlet opening 110 towards the material dropping opening 310. When the grains are transported to the material dropping opening 310, they fall from the material guiding channel 300 into the temporary storage bin 100. And the grains start to accumulate at a position above the discharge opening 120. During the accumulation process, the grains will flow in all directions and accumulate relatively evenly from the bottom to the top at the bottom of the temporary storage bin 100. Thus, the grains will not only accumulate on one side in the temporary storage bin 100. When the sensor 200 senses that the grains have piled up to a certain height, a feedback signal is sent to the screw type lifting device 500 to stop feeding. The sensor 200 can also be connected to the motor 420 at the same time. When the screw type lifting device 500 stops feeding, the motor 420 also stops working. By using the cooperation of the material guiding channel 300 and the feeding assembly, the grains are transported to above the discharge opening 120 before falling into the temporary storage bin 100, achieving the effect of uniform stacking and facilitating the control of the accuracy of the amount of grains entering the temporary storage bin 100.

[0023] In some specific embodiments of the present invention, such as Figure 2As shown, the material guiding channel 300 can be formed into a long strip arc-shaped supporting plate by bending the plate along the long side direction. That is, the upper part of the material guiding channel 300 is in an open state, and the material guiding screw 410 is installed on the material guiding channel 300 along the long side direction of the material guiding channel 300. Such a structure can effectively avoid the problem of grain blockage in the material guiding channel 300 in cases such as the asynchronous operation of the screw type lifting device 500 and the material guiding screw 410, or the conveying speed of the material guiding screw 410 being slower than that of the screw type lifting device 500. During the transportation of grains on the material guiding channel 300, the grains mainly fall into the temporary storage bin 100 from the material dropping port 310, and the grains can also be scattered from both sides of the material guiding channel 300 into the temporary storage bin 100, achieving the effects of improving the material dropping speed and uniform material dropping.

[0024] In some specific embodiments of the present invention, a plurality of diversion ports 320 are provided along the long side direction of the material guiding channel 300. During the transportation of grains on the material guiding channel 300 along with the material guiding screw 410, some grains will fall into the temporary storage bin 100 from the diversion ports 320, further enabling the grains to be evenly distributed and fall into the temporary storage bin 100.

[0025] In some specific embodiments of the present invention, the caliber of the diversion port 320 is smaller than that of the material dropping port 310. This enables the grains to mainly fall into the temporary storage bin 100 from the material dropping port 310, while the diversion port 320 plays an auxiliary role in material dropping.

[0026] In some specific embodiments of the present invention, a material guiding plate 111 is provided at the connection between the feeding port 110 and the material guiding channel 300, which is inclined downward. As shown in the figure, after the screw type lifting device 500 lifts the grains to the feeding port 110, the grains will then fall obliquely downward along the material guiding plate 111 into the material guiding channel 300, effectively avoiding the blockage caused by the accumulation of grains at the feeding port 110.
