Abstract
Description
Technical Field
[0001] The invention relates to the technical field of conveying equipment, and in particular to a multifunctional grain conveying system. Background Art
[0002] During the transportation process, grains usually need to be separated from impurities before they can be transported to the corresponding process or stored in the warehouse. The purpose is to remove impurities in the grains before they are transported to the destination, so as to improve the quality and purity of the grains. In the prior art, grain sorting mainly includes manual sorting, which is the most traditional sorting method. The staff will manually select unqualified grains by naked eye observation. Although this method is simple and easy to implement, it is inefficient and cannot handle a large amount of grains. Therefore, another mainstream sorting equipment was born, namely the multifunctional grain conveying system. Generally speaking, the working principle of the multifunctional grain conveying system mainly includes optical sorting and intelligent screening. It is a modern sorting technology. It uses the optical properties of grains such as color and gloss for sorting. It uses machine vision technology to automatically identify and remove unqualified grains. The sorting efficiency is extremely high and the sorting is relatively accurate. However, the biggest defect is that it is expensive. In addition, due to the use of a large number of sensor elements and electrical automatic control programs, the stability is poor and it is prone to failure. Moreover, general staff cannot maintain it in time and need to be responsible for it.
[0003] Another mainstream screening method is mechanical sorting, which includes screening, specific gravity sorting, wind sorting, etc. These methods use the differences in physical properties of grain particles such as size, shape, and density to separate particles of different densities through sieve holes of different specifications or wind power. Among them, wind screening is the most widely used method. The wind screening machine mainly relies on wind blowing to remove the empty shells, straw residues, dust, etc. of the slag in the grain. It is mainly used for the separation and screening of grains mixed with such impurities, which is also the main purpose of general grain screening. The existing wind-powered grain screening and separation equipment, relying on the development of information technology and the improvement of automation level, is actually transitioning to intelligent screening equipment, which has caused the procurement cost of the sorting machine to rise steadily, and the technical maintenance professional quality of the operator is getting higher and higher. It also brings the majority of users the almost only use defect of poor economy. Large grain producers can naturally spend huge costs to select and purchase, but as a general grain sorting user, it is not necessary and impractical. Therefore, how to take into account the excellent effects of sorting efficiency and economy is worthy of research and design by technical personnel in this field. Summary of the invention
[0004] In view of the deficiencies in the prior art, the present invention provides a multifunctional grain conveying system to solve the problem that grain containing dust, empty shells and straw debris cannot be separated and screened quickly and economically during transportation.
[0005] To achieve the above object, the present invention provides the following technical solution: a multifunctional grain conveying system, comprising a wind-selection fan for blowing toward grain, wherein the wind-selection fan is provided at least in two places, a first wind-selection fan is provided on a hinged first conveying plate, the first conveying plate can be hinged and swung around a certain point of itself in a vertical plane, and during the hinged swing, the grain falls from above the middle section of the first conveying plate in the process of the outlet end rising, and is swept by the first wind-selection fan along the width direction of the first conveying plate;
[0006] A second conveying plate is provided below the first conveying plate, the second conveying plate can move in a vertical plane, and when the outlet end of the second conveying plate is tilted upward, the outlet end of the first conveying plate is tilted downward, so that part of the grain on the first conveying plate falls onto the second conveying plate, and is swept and dusted by a second air separation fan arranged between the two conveying plates during the falling process; as the outlet end of the second conveying plate further tilts upward on the second conveying plate, the grain falling onto the second conveying plate slides toward the lower end of the second conveying plate at this time, and during the sliding process, after being filtered by a section of the filter screen on the second conveying plate, some impurities and dust with a particle size smaller than the grain leak out of the filter screen;
[0007] When the outlet end of the second conveying plate subsequently begins to tilt downward, the grain on its surface gradually slides out of its outlet end and falls into a grain frame just below it.
[0008] Furthermore, the swinging or rotating of the first conveying plate and the second conveying plate is driven by a motor or a hydraulic cylinder.
[0009] Furthermore, a counterweight is suspended at one end of the first conveying plate away from its outlet end; the first conveying plate is hinged to a frame at a middle position through a hinge column, a sliding plate which is vertically slidably mounted is hinged to the rear side surface of the outlet end of the first conveying plate, a hook is slidably mounted on the side surface of the upper portion of the sliding plate, and the hook is slidably mounted along the length direction of the sliding plate, a transmission rod is slidably mounted on the hook, one end of the hook is linearly slidably mounted in a sliding hole on the transmission rod, the second conveying plate is fixed as a whole in parallel with the transmission rod, one end of the transmission rod is fixed to a self-rotating driving shaft through a rotating arm, an arc rod and an arc strip are coaxially fixed to the driving shaft, wherein the arc strip is fixedly connected to the cylindrical surface of the driving shaft, and the arc strip is arranged on two opposite sides of the driving shaft with the arc rod;

DETAILED DESCRIPTION
[0029] This specification will clearly and completely express the technical solutions in the following examples based on the drawings of the embodiments of the present invention. The implementation methods described in this specification are only some of the embodiments of the present invention, not all of them. All other embodiments extended and inspired by those skilled in the art based on these embodiments in this application without creative work should fall within the scope of protection of the present invention.
[0030] like Figure 1 A multifunctional grain conveying system shown in the figure includes a winnowing fan for blowing toward the grain, and the winnowing fan is provided in at least two places. The first winnowing fan 3 is arranged on a hinged first conveying plate 1, and the first conveying plate 1 can be hinged and swung around a certain point of itself in a vertical plane. When the hinged swing is performed, the grain falls from the middle section of the first conveying plate 1 while its outlet end is raised, and is swept by the first winnowing fan 3 along the width direction of the first conveying plate 1.
[0031] A second conveying plate 9 is provided below the first conveying plate 1. The second conveying plate 9 can move horizontally in a vertical plane, and when the outlet end of the second conveying plate 9 tilts upward, the outlet end of the first conveying plate 1 tilts downward, so that part of the grain on the first conveying plate falls onto the second conveying plate 9, and is blown and dusted by the second air separation fan 4 arranged between the two conveying plates during the falling process; as the outlet end of the second conveying plate 9 further tilts upward on the second conveying plate 9, the grain falling onto the second conveying plate 9 slides toward the lower end of the second conveying plate 9 at this time, and in the process of sliding, after being filtered by a section of filter screen (not shown in the figure) on the second conveying plate 9, some impurities and dust with a particle size smaller than that of the grain leak out from the filter screen. As for the filter screen, it can be directly a stainless steel hollow plate embedded in the second conveying plate 9 as a bottom plate.
[0032] When the outlet end of the second conveying plate 9 then begins to tilt downward, the grains on its surface gradually slide out of the outlet end and fall into a grain frame 21 just below it. In order to separate the grains from dust, scum, etc. as much as possible, a third air separation fan may be provided on one side between the outlet end of the second conveying plate 9 and the grain frame 21 moved below it to perform the final air separation and impurity removal.
[0033] Specifically in practice, the swing or rotation of the first conveying plate 1 and the second conveying plate 9 is driven by a motor or a hydraulic cylinder. The structure of the conveying plate can be as follows: Figure 4 As shown, there is a shallow groove on the surface for conveying grains. The reason why it is called a shallow groove is that during air separation, the grains should not be covered too thickly, otherwise the sorting effect will be affected.
[0034] Specifically in practice, a counterweight 15 is hung on the end of the first conveying plate 1 away from its outlet end; the first conveying plate 1 is hinged to a frame through a hinge column 2 at the middle position, and a sliding plate 5 that is vertically slidably installed is hinged to the rear side of the outlet end of the first conveying plate 1, and a hook 7 is slidably installed on the side of the upper part of the sliding plate 5, and the hook is slidably fitted along the length direction of the sliding plate 5, and a transmission rod is slidably installed on the hook 7, and one end of the hook 7 slides linearly in a sliding hole on the transmission rod, and the second conveying plate 9 is fixed as a whole in parallel with the transmission rod, and one end of the transmission rod is fixed to a self-rotating driving shaft 10 through a rotating arm 13, and an arc rod 11 and an arc strip plate 12 are coaxially fixed to the driving shaft 10, wherein the arc strip plate 12 is fixedly connected to the cylindrical surface of the driving shaft 10, and is arranged on two opposite sides of the driving shaft 10 with the arc rod 11.
[0035] The arc rod 11 is located on the outside of the arc strip 12, and during the rotation of the driving shaft 10, when the arc rod 11 contacts the bottom of the first conveying plate 1, the outlet end of the first conveying plate 1 is tilted downward at a fixed angle, and at this time, the rotating arm 13 brings the transmission rod to make the outlet end of the second conveying plate 9 tilt upward in a translation state. Conversely, when the arc strip 12 contacts the bottom of the first conveying plate 1, the outlet end of the second conveying plate 9 is tilted downward in a translation state.
[0036] In practice, the transmission rod is a rack 8 . During manufacture, the rack 8 can be fixed to the aforementioned rotating arm 13 via a round rod 14 . The sliding plate 5 is provided with a first strip hole 6 located at the upper part and a second strip hole 16 located at the lower part, the two strip holes are on the same straight line with each other, and the other end of the hook 7 is slidably mounted in the first strip hole 6; at the same time, the multifunctional grain conveying system in this embodiment also includes a driven gear ring 19, the driven gear ring 19 is rotatably mounted on a mounting block 17, the mounting block 17 is fixed on the frame, and the mounting block 17 is slidably located in the second strip hole 16. During the contact between the arc rod 11 and the first conveying plate 1, the hook 7 is located at the upper end of the first strip hole 6, so that the rack 8 and the driven gear ring 19 can just freely maintain meshing. During the contact between the arc strip plate 12 and the first conveying plate 1, the free end of the first conveying plate 1 is tilted upward, so that the sliding plate 5 moves vertically upward with the mounting block 17 as a guide rail, and the bottom end side wall of the first strip hole 6 at this time moves upward with the other end of the hook 7, so that the hook 7 moves up with the rack 8 and disengages from the meshing with the driven gear ring 19.
[0037] Specifically in practice, a plurality of connecting rods 20 are fixed in a circular array on the front end side wall of the gear shaft 18 of the driven gear ring 19, and a grain frame 21 is fixed to the end of the connecting rod 20. When the whole formed by the rack 8 and the second conveying plate 9 is in a translational state with an upward tilt at the outlet end, the driven gear ring 19 rotates by an angle due to the engagement of the rack 8, so that the grain frame 21 moves just below the outlet end of the second conveying plate 9, and receives the fallen grain when the whole formed by the rack 8 and the second conveying plate 9 is in a translational state with an downward tilt at the outlet end.
[0038] Specifically in practice, a latch 22 is fixed vertically to the front door at the bottom end of the sliding plate 5. When the rack 8 and the driven gear ring 19 are disengaged due to the upward movement of the sliding plate 5, the latch 22 just moves upward and is inserted into the tooth gap between a pair of adjacent gear teeth of the driven gear ring 19 to prevent the driven gear from rotating.
[0039] As a very useful and ingenious design, the key lies in that a bayonet 22 is fixed vertically to the front surface of the bottom end of the sliding plate 5. When the rack 8 and the driven gear ring 19 are disengaged due to the upward movement of the sliding plate 5, the bayonet 22 just moves up and is inserted into the tooth gap between a pair of adjacent gear teeth of the driven gear ring 19 to prevent the driven gear from rotating, so that the driven gear ring 19 will not rotate at will, and the grain frame 21 that has moved into place will stay at the set position, waiting for subsequent grain to slide down and fall in; as a more preferred structure, the gear teeth of the driven gear ring 19 can be made into an isosceles triangle structure, and the vertex angle can be 30°, so that the bayonet 22 can be moved up at any time and inserted into the corresponding tooth gap.
[0040] Specifically in practice, the counterweight 15 is connected to the end of the first conveyor plate 1 through a steel cable, and the counterweight 15 includes a plurality of detachable counterweight plates stacked together. More specifically, the counterweight 15 is installed between a pair of limit plates, the two limit plates are arranged parallel to each other and spaced apart, and the counterweight 15 is slidably located between the two limit plates and in smooth contact with the inner surfaces of the two limit plates.
[0041] It should be explained here that, in this specification, terms such as first and second are only used to distinguish one feature from another, and do not mean that there is a certain relationship or order between these technical features. The terms "including" and "comprising" refer to the inclusion of one or some technical means or features, specifically meaning that there are other existing or non-existing technical features that have not been included. The discussion in the above embodiments is only a representative example for the present invention, and is by no means the only restrictive constraint feature. A person of ordinary skill in the art should understand that, without departing from the technical content recorded in all the claims of this application, some simple substitutions and modifications can be made, thereby changing or becoming equivalent to other specific embodiments and application scenarios. However, no matter how the adaptability is changed, these embodiments will inevitably fall within the scope of protection of the present invention.
