Description

Technical Field

[0001] The invention relates to the technical field of flour processing, in particular to a feeding device for whole wheat flour processing. Background Art

[0002] Whole wheat flour is a type of flour ground from the whole grain of wheat, which contains the bran, germ and endosperm of the wheat. Compared with white flour, whole wheat flour retains more nutrients, including dietary fiber, vitamins, minerals and antioxidants.

[0003] In the whole wheat flour processing process, a feeding device is needed. The Chinese invention patent with the publication number CN112044754B discloses a feeding device for flour processing, including a drying box, a pretreatment box and a transfer box. The right side of the connection between the transfer box and the drying box is provided with a through hole. A driving mounting plate is welded in the middle of the front end face of the pretreatment box, a driving motor is installed at the bottom of the driving mounting plate, and a fixing block is welded on the left side of the connection between the front end face of the pretreatment box and the driving mounting plate. Gears and transmission gears are installed at the upper and lower ends of the rotating rod respectively. The screened wheat enters the inner cavity of the transfer box through the discharge pipe, and the wheat is transported from left to right. The invention uses the dust exhaust fan to run to discharge the dust mixed in the wheat out of the transfer box, so as to avoid the dust mixed in the wheat and affect the quality of the flour. After the wheat falls into the inner cavity of the drying box, the pulley drives the steel pipe to rotate, and the steel pipe drives the stirring blade to rotate to stir the wheat, so as to achieve rapid drying, avoid the wheat from getting wet, and reduce the grinding efficiency.

[0004] However, after the wheat is placed in the drying box, when the wheat is piled up in the drying box, the wheat below the stirring rod cannot be evenly stirred, and the discharge port can only discharge the wheat at the nearest position instead of the completely dried wheat. The drying quality cannot be guaranteed, which may affect the production quality to a certain extent and cannot meet the production needs. Therefore, a feeding device for whole wheat flour processing is proposed to solve the above problems. Summary of the invention

[0009] Furthermore, a plurality of universal wheels are arranged at the bottom of the base, an embedding slot is opened at the top of the base, a driving box is embedded in the embedding slot and fixedly installed with the base, the top of the driving box is fixedly installed with the bottom of the processing box, and a feed port is opened at the top of the processing box.

[0010] Furthermore, a cross-shaped through hole is arranged inside the limiting cylinder, the transmission rod is a cross-shaped structure and vertically penetrates the limiting cylinder to the inside of the driving box, and a spiral stirring blade is arranged on the outside of the stirring rod.

[0011] Furthermore, the feeding barrel is a V-shaped structure and one end vertically penetrates the top wall of the processing box to the inside of the processing box, the output shaft of the feeding motor vertically penetrates the top wall of the feeding barrel to the inside of the feeding barrel, and a spiral feeding blade is provided on the outside of the feeding rod.

[0012] Furthermore, a transmission gear is arranged on the outer side of the transmission rod, a cross-shaped slot is arranged inside the transmission gear, the transmission rod vertically passes through the cross-shaped slot and is slidingly connected with the transmission gear, and the outer teeth of the transmission gear are embedded in the inner wall of the positioning gear disk and are connected with the positioning gear disk through the teeth transmission.

[0013] Furthermore, a gear is disposed on the outer side of the output shaft at the lower end of the dual-axis motor and is meshed and transmission-connected with a speed reduction gear, and a tooth pattern is disposed on the inner side wall of the rotating ring and is transmission-connected with the speed reduction gear through the tooth pattern.

[0014] Furthermore, a slidably connected locking cylinder is arranged on the outer side of the transmission rod, a cross-shaped slot used in conjunction with the transmission rod is arranged inside the locking cylinder, and the locking cylinder is embedded in the reset plate and is rotationally connected to the reset plate.

[0015] Furthermore, a conical block is arranged at the bottom of the transmission rod, and a plurality of jacking wedge blocks used in conjunction with the conical block are arranged at the top of the rotating ring.

[0016] Furthermore, the upper and lower ends of the reset spring are fixedly mounted to the bottom of the reset plate and the inner bottom wall of the drive box respectively.

[0017] Compared with the prior art, the present invention provides a feeding device for whole wheat flour processing, which has the following beneficial effects:

[0018] 1. The feeding device for whole wheat flour processing, after putting wheat into the processing box from the feeding port, controls the double-axis motor to rotate, the rotation of the positioning gear disk drives the transmission gear to rotate, and then drives the transmission rod to rotate, the rotation of the transmission rod drives the stirring rod and the spiral stirring blade to rotate synchronously, and the multiple spiral stirring blades stir the wheat located at the edge of the processing box to the center position below the feeding rod. At the same time, due to the spiral structure of the spiral stirring blades, the wheat located at the bottom is continuously turned toward the center, and the dry wheat on the top is moved to the edge position under the action of the spiral stirring blades.

[0019] 2. The feeding device for whole wheat flour processing drives the speed reduction gear to rotate through the output shaft at the lower end of the double-axis motor, and the rotation of the speed reduction gear drives the rotating ring to rotate. The rotation of the rotating ring drives the lifting wedge to embed into the bottom of the conical block to lift the conical block. The rise of the conical block pushes the transmission rod and the stirring rod to rise to a certain extent at the same time, so that the spiral stirring blade shakes up and down to push the wheat on the surface. The rise of the conical block drives the positioning cylinder and the reset plate to rise. The height change of the reset plate pulls the reset spring to stretch. After the lifting wedge is removed from the bottom of the conical block, the restoring effect of the reset spring causes the reset plate and the positioning cylinder to receive a downward force, so that the spiral stirring blade is also forced downward during the rotation, thereby driving another wave of wheat to flip, so that the wheat inside the processing box is fully and evenly stirred during drying.

DETAILED DESCRIPTION

[0027] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-6 A feeding device for whole wheat flour processing includes a base 1, a processing box 2 arranged on the top of the base 1, and a driving box 3 arranged inside the base 1. A feeding component 4 is arranged inside the processing box 2, and a driving component 5 is arranged inside the driving box 3.

[0029] See also Figure 1 In this embodiment, a plurality of universal wheels 6 are arranged at the bottom of the base 1, an embedding groove is opened at the top of the base 1, a driving box 3 is embedded in the embedding groove and fixedly installed with the base 1, the top of the driving box 3 is fixedly installed with the bottom of the processing box 2, and a feed port 7 is opened at the top of the processing box 2.

[0030] By injecting wheat into the feed port 7, the wheat enters the processing box 2 along the side wall of the feed port 7, pushing the universal wheel 6 to rotate and driving the base 1 to move toward the grinding equipment.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 In this embodiment, the feeding assembly 4 includes a plurality of limiting cylinders 41 rotatably connected to the bottom wall of the processing box 2, a transmission rod 42 slidably connected to the inside of the limiting cylinder 41, a stirring rod 43 fixedly installed on the top of the transmission rod 42, a feeding cylinder 44 fixedly installed on the top of the processing box 2, a feeding motor 45 fixedly installed on the top of the feeding cylinder 44, and a feeding rod 46 fixedly installed at the bottom of the output shaft of the feeding motor 45.

[0032] The interior of the limiting cylinder 41 in this embodiment is provided with a cross-shaped perforation, the transmission rod 42 is a cross-shaped structure and vertically penetrates the limiting cylinder 41 to the interior of the driving box 3, and the outer side of the stirring rod 43 is provided with a spiral stirring blade 47. There are four limiting cylinders 41 and transmission rods 42, which are arranged around the feeding rod 46. The transmission rod 42 can move up and down inside the limiting cylinder 41, and at the same time drive the stirring rod 43 to rotate, thereby pushing all the wheat on the outside to the center position below the feeding rod 46.

[0033] The feeding barrel 44 in this embodiment is of a V-shaped structure and one end thereof vertically passes through the top wall of the processing box 2 to the interior of the processing box 2. The feeding barrel 44 of the V-shaped structure is inserted upside down on the top of the processing box 2, so that the wheat rises inside the feeding barrel 44 under the rotation and absorption action of the feeding rod 46. When it rises to the V-shaped mouth, the wheat enters the other end of the feeding barrel 44 for the next step of processing; the output shaft of the feeding motor 45 vertically passes through the top wall of the feeding barrel 44 to the interior of the feeding barrel 44, and a spiral feeding blade 48 is provided on the outside of the feeding rod 46. The spiral feeding blade 48 is provided on the outside of the feeding rod 46, so that when the spiral feeding blade 48 rotates rapidly, the wheat below that has been fully dried can be drawn into the interior of the feeding barrel 44.

[0034] See also Figure 1-6 The driving assembly 5 includes a dual-axis motor 51 fixedly mounted on the bottom of the driving box 3, a positioning gear plate 52 fixedly mounted on the outer side of the output shaft at the upper end of the dual-axis motor 51, a speed reduction gear 53 rotatably connected to the inner bottom wall of the driving box 3, a rotating ring 54 rotatably connected to the inner bottom wall of the driving box 3, a telescopic limit rod 55 fixedly mounted on the inner bottom wall of the driving box 3, a reset plate 56 fixedly mounted on the top of the telescopic limit rod 55, and a reset spring 57 arranged on the outer side of the telescopic limit rod 55.

[0035] The outer side of the lower output shaft of the dual-axis motor 51 in this embodiment is provided with a gear and a speed reduction gear 53 for meshing transmission connection. The inner wall of the rotating ring 54 is provided with teeth and is connected to the speed reduction gear 53 through the teeth. When the dual-axis motor 51 rotates, it drives the speed reduction gear 53 to rotate, and the speed reduction gear 53 drives the rotating ring 54 to rotate synchronously.

[0036] The transmission gear 58 is arranged on the outer side of the transmission rod 42 in this embodiment, and a cross-shaped slot is arranged inside the transmission gear 58. The transmission rod 42 vertically penetrates the cross-shaped slot and is slidingly connected with the transmission gear 58. The sliding connection between the transmission gear 58 and the transmission rod 42 allows the transmission rod 42 to be raised and lowered under the action of other components. At the same time, the transmission rod 42 always keeps synchronous rotation with the transmission gear 58. The outer teeth of the transmission gear 58 are embedded in the inner wall of the positioning toothed disk 52 and are connected to the positioning toothed disk 52 through the teeth transmission. The positioning toothed disk 52 covers the outer side of the transmission gear 58, so that the positioning toothed disk 52 can drive the transmission gear 58 to rotate synchronously, and can prevent the transmission gear 58 from shifting up and down.

[0037] The outer side of the transmission rod 42 in this embodiment is provided with a slidably connected locking cylinder 59, and the interior of the locking cylinder 59 is provided with a cross-shaped slot used to cooperate with the transmission rod 42. The locking cylinder 59 is embedded in the interior of the reset plate 56 and is rotatably connected to the reset plate 56. A conical block 510 is provided at the bottom of the transmission rod 42. When the locking cylinder 59 rotates inside the reset plate 56, the bottom of the locking cylinder abuts against the top of the conical block 510. A plurality of lifting wedge blocks 511 used to cooperate with the conical block 510 are provided on the top of the rotating ring 54. The rotation of the lifting wedge block 511 can continuously push the conical block 510 to rise to a certain height, thereby pushing the transmission rod 42 to slide inside the locking cylinder 59 and the limiting cylinder 41.

[0038] The upper and lower ends of the reset spring 57 in this embodiment are fixedly installed on the bottom of the reset plate 56 and the inner bottom wall of the drive box 3 respectively. The two ends of the reset spring 57 pull the reset plate 56 and the drive box 3, so that after the conical block 510 rises a certain distance under the push of the lifting wedge block 511, the restoring effect of the reset spring 57 can quickly pull the conical block 510 down for reset.

[0039] The working principle of the above embodiment is:

[0040] After the wheat is placed into the processing box 2 from the feed port 7, the dual-axis motor 51 is controlled to rotate, and the rotation of the positioning gear plate 52 drives the transmission gear 58 to rotate, and then drives the transmission rod 42 to rotate. The rotation of the transmission rod 42 drives the stirring rod 43 and the spiral stirring blades 47 to rotate synchronously. The multiple spiral stirring blades 47 stir the wheat at the edge of the processing box 2 to the center position below the feeding rod 46. At the same time, due to the spiral structure of the spiral stirring blades 47, the wheat at the bottom is continuously flipped toward the center, and the dry wheat on the top is moved to the edge position under the action of the spiral stirring blades 47.

[0041] In addition, the output shaft at the lower end of the dual-axis motor 51 rotates to drive the speed reduction gear 53 to rotate, and the rotation of the speed reduction gear 53 drives the rotating ring 54 to rotate. The rotation of the rotating ring 54 drives the lifting wedge 511 to embed into the bottom of the conical block 510 to lift the conical block 510. The rise of the conical block 510 pushes the transmission rod 42 and the stirring rod 43 to rise to a certain extent at the same time, so that the spiral stirring blade 47 shakes up and down, pushing the wheat on the surface away, and the rise of the conical block 510 drives the positioning tube 59 and the reset plate 56 to rise. The height change of the reset plate 56 pulls the reset spring 57 to stretch. After the lifting wedge 511 is removed from the bottom of the conical block 510, the restoring effect of the reset spring 57 causes the reset plate 56 and the positioning tube 59 to receive a downward force, which drives the spiral stirring blade 47 to rotate while also being pulled downward, thereby driving another wave of wheat to flip, thereby solving the problem of poor mixing during wheat drying and poor drying effect during flour processing and feeding.

[0042] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and they can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the control method and circuit connection are no longer explained in detail in this embodiment.
