Abstract
Description
Technical Field
[0001] This utility model relates to the field of glutinous rice ball processing technology, specifically to a glutinous rice ball powder pretreatment device. Background Technology
[0002] Tangyuan, a traditional Chinese festival food, is loved by the public. With the acceleration of food industrialization, large-scale, efficient and high-quality production of tangyuan has become a market demand. Tangyuan flour, as the main raw material of tangyuan, has its pre-treatment effect directly affecting the taste, quality and production efficiency of tangyuan.
[0003] In the early days, the production of glutinous rice flour was mostly done by hand, with raw materials such as glutinous rice being processed through manual screening, grinding, and stirring. Modern glutinous rice flour pretreatment equipment usually includes multiple functional modules such as raw material cleaning, crushing, sieving, and mixing. Currently, the mixing pretreatment process lacks effective mixing equipment, resulting in unsatisfactory mixing effects.
[0004] Currently, the mixing mechanism inside the mixing equipment is relatively simple. Since glutinous rice flour is a powdery substance, it is easy to clump and accumulate. The simple mixing mechanism does not have a turbulence effect and tends to form a unidirectional mixing, which leads to uneven mixing of glutinous rice flour with other raw materials. Poor mixing pretreatment effect will affect the quality of the final glutinous rice. In view of this, we propose a glutinous rice flour pretreatment equipment. Utility Model Content
[0005] The purpose of this invention is to provide a pretreatment device for glutinous rice flour to solve the problems mentioned in the background art.

The mixing assembly includes:
[0008] An asynchronous motor is fixedly installed on the outer wall of the frame. One end of the output end of the asynchronous motor is fixedly installed with a rotating shaft, and the other end of the rotating shaft is fixedly installed with a rotating drum. The two ends of the rotating drum are rotatably installed inside the side wall of the mixing tank through sealed bearings.
[0009] A connecting rod is fixedly connected to one end of the connecting rod on the arc-shaped outer wall of the rotating cylinder, and a propeller is fixedly installed on the other end of the connecting rod. There are two sets of connecting rods and propellers, and the two sets of propellers rotate in opposite directions.
[0010] An arc-shaped plate is fixedly installed on the arc-shaped inner wall of the rotating drum. A servo motor is fixedly installed on the side wall of the arc-shaped plate. A stirring rod is fixedly installed at the output end of the servo motor. One end of the stirring rod is rotatably installed inside the arc-shaped side wall of the rotating drum through a sealed bearing. A conical auger is fixedly installed on the outer wall of the other end of the stirring rod. Two sets of arc-shaped plates, servo motors, stirring rods, and conical augers are provided, and the two sets of conical augers rotate in opposite directions. A heat dissipation plate is snapped into the inside of the end of the rotating drum away from the asynchronous motor.
[0011] Preferably, the connecting rods on a single propeller are provided in multiple sets, so that the propeller rotates more stably.
[0012] Preferably, the vertical cross-sectional projection of the conical auger propeller is conical, thereby better turbulenting of the mixture.
[0013] Preferably, an auxiliary component is provided on the outside of the collection bucket. The auxiliary component includes a slide rail. The slide rail is fixedly installed on the arc-shaped side wall at the bottom of the mixing box. There are two sets of slide rails. A discharge plate is slidably installed between the two sets of slide rails. The arc-shaped inner wall of the discharge plate slides against the arc-shaped outer wall of the mixing box. The size of the discharge plate is adapted to the discharge trough on the mixing box. A hydraulic cylinder fixing end is fixedly installed on the side wall of the frame. The piston end of the hydraulic cylinder is fixedly connected to the outer wall of the center of the discharge plate.
[0014] Preferably, a fixing plate is fixedly installed on the outer wall of the top of the mixing box, one end of a rotating plate is hinged to the fixing plate, and a box cover is fixedly installed on the other end of the rotating plate. An electric push rod fixing end is hinged to the frame, the piston end of the electric push rod is hinged to the box cover, and a handle is fixedly installed on the outer wall of the box cover.
[0015] Preferably, there are two sets of the fixed plate, rotating plate and electric push rod, and both sets of the fixed plate, rotating plate and electric push rod are mirror images of the vertical center line of the mixing box at both ends of the box cover, so as to move the box cover better.
[0016] Compared with the prior art, this utility model provides a pretreatment device for glutinous rice flour, which has the following features:
[0017] Beneficial effects:
[0018] 1. This glutinous rice flour pretreatment equipment, in order to better pre-treat the glutinous rice flour raw materials by mixing components, starts the asynchronous motor on the frame, causing the rotating shaft to rotate, which in turn drives the rotating drum to rotate, thereby cooperating with the connecting rod to drive the propeller to rotate. The two sets of propellers rotate in opposite directions, which better lateral turbulence of the material. At the same time, the servo motor on the arc plate is started, causing the stirring rod to drive the conical auger to rotate. Since the multiple sets of conical augers rotate in opposite directions, the longitudinal turbulence is further enhanced, resulting in better mixing effect. The heat dissipation plate better dissipates heat from the servo motor, thus enabling better pre-treatment of the glutinous rice flour raw materials.
[0019] 2. To enhance the practicality of this glutinous rice flour pretreatment equipment, auxiliary components are incorporated. When mixing is complete and discharge is required, the hydraulic cylinder is activated, causing the discharge plate to slide on the slide rail, thereby opening the discharge chute and allowing the mixed material to fall into the collection bucket. When the electric push rod is activated, the lid and handle can swing, and the rotating plate rotates on the fixed plate, thus better opening and closing the top opening of the mixing box. This prevents material from splashing outside the equipment during mixing, further enhancing the practicality of the equipment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] In this application, the term "above" indicates the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.
[0031] Please see Figure 1 - Figure 8 This utility model provides a technical solution:
[0032] A pretreatment device for glutinous rice flour includes a frame 1, a collection bucket 2 inside the frame 1, a mixing box 3 fixedly installed inside the top of the frame 1, a through discharge chute on the arc-shaped side wall at the bottom of the mixing box 3, and a feeding opening at the top of the mixing box 3.
[0033] In one embodiment of this utility model, a mixing component 4 is provided on the frame 1. The mixing component 4 includes an asynchronous motor 41. The asynchronous motor 41 is fixedly installed on the outer wall of the frame 1. One end of the rotating shaft 42 is fixedly installed at the output end of the asynchronous motor 41, and a rotating drum 43 is fixedly installed at the other end of the rotating shaft 42. The two ends of the rotating drum 43 are rotatably installed inside the side wall of the mixing tank 3 through sealed bearings. One end of the connecting rod 44 is fixedly connected to the arc-shaped outer wall of the rotating drum 43. A propeller 45 is fixedly installed at the other end of the connecting rod 44. There are two sets of connecting rods 44 and propellers 45, and the two sets of propellers 45 rotate in opposite directions. In addition, there are two sets of connecting rods 44 on a single propeller 45, so that the propeller 45 rotates more stably. The arc-shaped inner wall of the rotating drum 43 is fixedly connected to the connecting rod 44. An arc-shaped plate 46 is installed, and a servo motor 47 is fixedly installed on the side wall of the arc-shaped plate 46. A stirring rod 48 is fixedly installed at the output end of the servo motor 47. One end of the stirring rod 48 is rotatably installed inside the arc-shaped side wall of the rotating drum 43 through a sealed bearing. A conical auger paddle 49 is fixedly installed on the outer wall of the other end of the stirring rod 48. There are two sets of arc-shaped plate 46, servo motor 47, stirring rod 48 and conical auger paddle 49, with two in each set. The two sets of conical auger paddles 49 rotate in opposite directions and are perpendicular to each other. In addition, the vertical cross-sectional projection of the conical auger paddle 49 is conical, which can better turbulent the mixture. A heat sink 410 is snapped into the inside of the end of the rotating drum 43 away from the asynchronous motor 41.
[0034] In this embodiment, the operator first pours the glutinous rice flour raw material into the mixing chamber 3 through the feed opening at the top of the mixing chamber 3. After the chamber cover 56 is closed, the asynchronous motor 41 on the frame 1 is turned on, causing the rotating shaft 42 to rotate synchronously with the output end of the asynchronous motor 41. The rotation of the rotating shaft 42 drives the rotating drum 43 to rotate. The rotating drum 43 achieves stable rotation inside the side wall of the mixing chamber 3 through the sealed bearings at both ends, ensuring the sealing during the rotation process and preventing material leakage. When the rotating drum 43 rotates, the connecting rod 44 also performs a circular motion. The movement of the connecting rod 44 drives the propeller 45 to rotate. When the rotating drum 43 rotates, the two sets of propellers 45 rotate synchronously, forming a lateral turbulence in the material in the mixing chamber 3. This design of opposite rotation directions allows the material to generate convection in the horizontal direction, increasing the mixing effect between materials. Meanwhile, the servo motor 47 on the arc plate 46 is also started, and its output end drives the stirring rod 48 to rotate. One end of the stirring rod 48 rotates inside the arc-shaped side wall of the rotating drum 43 through a sealed bearing, ensuring the stability and sealing of the stirring rod 48's rotation. During the rotation of the stirring rod 48, the conical auger paddle 49 rotates accordingly. When they rotate, they can form longitudinal turbulence in the material, pushing the material from bottom to top or from top to bottom. This works in conjunction with the transverse turbulence formed by the propeller 45 to further increase the mixing effect of the material. During the operation of the servo motor 47, the heat sink 410 plays a role. The heat sink 410 can dissipate the heat generated by the servo motor 47 in a timely manner, ensuring that the servo motor 47 continues to operate stably in a suitable temperature environment, thereby ensuring the efficiency and stability of the entire mixing process.
[0035] In one embodiment of this utility model, an auxiliary component 5 is provided on the outside of the collection bucket 2. The auxiliary component 5 includes a slide rail 51. The slide rail 51 is fixedly installed on the arc-shaped side wall at the bottom of the mixing box 3. Two sets of slide rails 51 are provided. A discharge plate 52 is slidably installed between the two sets of slide rails 51. The arc-shaped inner wall of the discharge plate 52 slides against the arc-shaped outer wall of the mixing box 3. The size of the discharge plate 52 is adapted to the discharge trough on the mixing box 3. A hydraulic cylinder 53 is fixedly installed on the side wall of the frame 1. The piston end of the hydraulic cylinder 53 is fixedly connected to the center outer wall of the discharge plate 52. In addition, the top outer wall of the mixing box 3 is... A fixed plate 54 is fixedly installed, and a rotating plate 55 is hinged to one end of the fixed plate 54. A box cover 56 is fixedly installed to the other end of the rotating plate 55. An electric push rod 57 is hinged to the fixed end of the frame 1. The piston end of the electric push rod 57 is hinged to the box cover 56. A handle 58 is fixedly installed on the outer wall of the box cover 56. In addition, there are two sets of fixed plates 54, rotating plates 55 and electric push rods 57. Both sets of fixed plates 54, rotating plates 55 and electric push rods 57 are mirror images of the vertical center line of the mixing box 3 and are mirror images of the two ends of the box cover 56, so as to better move the box cover 56.
[0036] In this embodiment, when in use, the electric push rod 57 is activated. The piston end of the electric push rod 57 pulls the box cover 56 to swing, and the rotating plate 55 rotates on the fixed plate 54. In this way, the box cover 56 can smoothly close the top opening of the mixing box 3, ensuring that the material will not splash out from the top during the subsequent mixing process. After the glutinous rice flour raw material has completed the mixing pretreatment in the mixing box 3, the mixed material needs to be output. At this time, the hydraulic cylinder 53 on the frame 1 is activated, and its piston end pulls back the discharge plate 52 fixedly connected to it. The discharge plate 52 slides along the slide rail 51. Since the arc-shaped inner wall of the discharge plate 52 slides against the arc-shaped outer wall of the mixing box 3, and the size of the discharge plate 52 is adapted to the discharge trough on the mixing box 3, when the discharge plate 52 slides, the discharge trough is gradually... When the mixing chamber 3 is opened, the mixed materials inside, under the action of gravity and with the rotation of the propeller 45 in the mixing component 4, are gathered towards the discharge chute. Note that the servo motor 47 is turned off, so that the materials can fall more easily into the collection bucket 2 located inside the frame 1 through the open discharge chute. The collection bucket 2 is used to collect the mixed glutinous rice flour materials, thus completing the mixing pretreatment for subsequent processing. After the discharge is completed, if it is necessary to feed the mixing chamber 3 again, the electric push rod 57 can be started again. The electric push rod 57 pushes the chamber cover 56 and the handle 58 to swing, and the rotating plate 55 rotates in the opposite direction on the fixed plate 54, so that the chamber cover 56 opens, preparing for the next batch of raw materials to be poured into the mixing chamber 3, thus improving the practicality and safety of the equipment.

The controller is a conventional and known device that can control the asynchronous motor 41, servo motor 47, hydraulic cylinder 53, and electric push rod 57.

The machinery, parts, and equipment are all conventional models in the prior art.

Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
