DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 3The utility model provides a technical solution: a small fully automatic grain thresher, comprising a base 1, a loading assembly 200 is installed on the top of the base 1, a grain thresher body 3 is fixedly installed on the top of the base 1, and a discharging assembly 400 for providing raw materials to the loading assembly 200 is installed on the top of the base 1; through the coordinated use of the loading assembly 200 and the discharging assembly 400 on the top of the base 1, it can achieve high automation working capability while limiting and protecting the place where impurity screening work is carried out, and at the same time, it can also improve a certain impurity separation effect, so that the overall work quality can be further improved, and there is no need for staff to continuously carry out material loading work, which saves staff time and enables them to participate in other more valuable work, thereby effectively improving the practicality of the grain thresher.

[0025] In this embodiment, the loading assembly 200 is a structure for automatic loading and impurity separation.

[0026] like Figure 1 、 Figure 2 and Figure 3 As shown, the feeding assembly 200 includes a feeding barrel 201 fixed on the top of the base 1, a servo motor 202 fixedly installed on the top of the feeding barrel 201, a drive shaft 203 rotatably connected to the inner side of the feeding barrel 201 through a bearing, a spiral conveying blade 204 fixed on the outside of the drive shaft 203, a discharge pipe 205 fixed on the top of the outer side of the feeding barrel 201, a flat tube 206 fixed at the bottom of the discharge pipe 205 and with the bottom end extending to the input end of the grain thresher body 3, two connecting holes 207 opened on the outside of the flat tube 206, a mesh plate 208 fixed on the inner side of the connecting hole 207, a collecting pipe 209 fixed on the inner side of the back connecting hole 207, a screening fan 210 fixedly installed on the inner side of the front connecting hole 207, a plurality of support columns 211 fixed between the bottom of the feeding barrel 201 and the top of the base 1, and a collecting box 212 placed on the top of the base 1 and with an opening on the top.

[0027] It should be noted that the top end of the loading barrel 201 extends to the top of the grain thresher body 3, so that the loading barrel 201 can stably perform the conveying work through the support between several support columns 211, and the output shaft of the servo motor 202 passes through the outside of the loading barrel 201 and is fixedly connected to the top end of the drive shaft 203, so that the servo motor 202 can drive the drive shaft 203 to rotate.

[0028] In addition, the discharge pipe 205 is circular, and the transition between the inner side of the discharge pipe 205 and the inner side of the flat tube 206 is arc-shaped, so that the discharge pipe 205 can discharge the material inside the upper barrel 201 normally, and can also move smoothly to the inside of the flat tube 206 under the action of the arc-shaped connection transition, so that the material can be limited and concentrated in a flat shape, which is convenient for blowing separation.

[0029] At the same time, the positions of the two connecting holes 207 correspond to each other, the back mesh plate 208 is located on the front side of the collecting pipe 209, and the front mesh plate 208 is located on the back side of the screening fan 210, so that the two mesh plates 208 can impose certain restrictions on the interior of the connecting hole 207, so that impurities and dust can be discharged normally while not making it easy for the grain raw materials to be removed. Among them, the wind force of the screening fan 210 needs to be determined according to the actual situation. Only a breeze is needed to blow out the dust, and the wind force should be appropriately increased when the impurities need to be blown out to meet the separation requirements of the impurities, so that the dust and impurities can be blown into the interior of the collecting pipe 209 by the wind for discharge. The bottom end of the collecting pipe 209 extends downward to the top of the collecting box 212, so that the impurities and dust inside the collecting pipe 209 can enter the interior of the collecting box 212 for storage.

[0030] In this embodiment, the discharge assembly 400 is a structure for placing a large amount of grain raw materials at one time.

[0031] like Figure 1 As shown, the discharge assembly 400 includes a lower hopper 401 fixed to the top of the upper barrel 201, a fixed column 402 fixed to the top of the base 1, a discharge box 403 fixed between the fixed column 402 and the top of the lower hopper 401, and a dust cover 404 hinged to the top of the discharge box 403 by a hinge.

[0032] It should be noted that a discharge hole connected to the interior of the discharge hopper 401 is provided at the bottom of the discharge box 403, and the inner bottom wall of the discharge box 403 is inclined toward the side close to the discharge hole, so that the grain raw materials inside the discharge box 403 can enter the interior of the discharge hopper 401 through the discharge hole, and a feed port located at the bottom of the dust cover 404 is provided at the top of the discharge box 403, so that the grain raw materials can enter the interior of the discharge box 403 through the feed port.

[0033] The working principle of the above embodiment is:

[0034] During operation, the material is poured into the discharge box 403 at one time, so that it enters the upper barrel 201 through the lower hopper 401 and waits for transportation. The servo motor 202 is started to drive the drive shaft 203 to rotate, and the spiral conveying blade 204 can continuously move the material inside the upper barrel 201 to the side close to the discharge pipe 205, so that the material enters the flat tube 206 through the discharge pipe 205. Under the limitation of the internal space, the material can be distributed as flat as possible, so that it can be blown more effectively by the screening fan 210. The screening fan 210 is started and the dust and impurities on the surface of the material are blown away at a low wind speed, so that the dust and impurities can pass through the corresponding mesh plate 208 and the connecting hole 207 into the collection pipe 209, and finally collected by the collection box 212. The processed material enters the interior of the grain thresher body 3 for threshing, thereby realizing fully automatic grain threshing.

[0035] Compared with the existing technology, this small fully automatic grain thresher, through the coordinated use of the loading component 200 and the discharging component 400 on the top of the base 1, can achieve high automation working ability while limiting and protecting the place where impurity screening work is done, and at the same time improve a certain impurity separation effect, so that the overall work quality can be further improved, and there is no need for staff to continuously load materials, saving staff time and enabling them to participate in other more valuable work, thereby effectively improving the practicality of the grain thresher and solving the problem that the existing grain thresher has a low degree of automation during actual use and affects the surrounding environment.

The main controller can be a conventional known device that controls a computer, etc., and can be implemented through simple programming by technicians in this field.
