Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice production technology, specifically to a drying device for rice production. Background Technology
[0002] Rice processing and drying refers to the process of pre-treating and cleaning freshly harvested rice, and then placing it in specialized drying equipment to remove excess moisture and achieve an appropriate moisture content, thereby ensuring the quality and edibility of the rice.
[0003] For example, Chinese patent document CN219347100U discloses a rice processing and drying device, which relates to the field of grain processing technology. It includes a drying box and a rice drying mechanism. An electric dryer is installed on the upper side of the drying box, a discharge port is provided on the left side of the drying box, and a rice drying mechanism is installed inside the drying box.
[0004] In the above technical solution, by setting a rotating and opening sealing plate, the rice is poured into the funnel trough by the staff. After being poured in, the rice will be screened by the filter plate to filter out impurities such as powdery rice flour and broken rice grains, thereby ensuring that the dried rice is high-quality rice. The screened rice will be guided out through the waste guide trough to prevent waste from being mixed into the drying box.
[0005] However, in actual use, it was found that after the rice entered the conveying device, the rice grains would pile up and block each other, which prevented the moisture in the rice grains from being directly exposed, thus affecting the subsequent drying of the rice. Summary of the Invention
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a drying device for rice production, which can lay the rice flat before drying to facilitate thorough drying.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a drying device for rice production, comprising a feeding hopper, a conveyor belt below the feeding hopper, a drying hopper on the side of the conveyor belt away from the feeding hopper, a dryer on the drying hopper, and two symmetrically arranged baffles between the feeding hopper and the drying hopper. Each baffle includes a transverse baffle and a longitudinal baffle, which are perpendicular to each other. The transverse baffle and the longitudinal baffle spread the accumulated rice on the conveyor belt by moving laterally and longitudinally, respectively.
[0008] The present invention is further configured such that: guide rods and rotatable one-way screws are respectively provided on both sides of the conveyor belt; a connecting frame is provided above the conveyor belt; the two ends of the connecting frame are respectively fitted onto the outer periphery of the guide rods and the one-way screws, forming a sliding fit and a threaded fit respectively; the connecting frame is connected to a longitudinal moving mechanism; the longitudinal moving mechanism is used to drive the dial plate to move longitudinally; one end of the one-way screw is connected to a drive motor; the drive motor is used to drive the one-way screw to rotate, thereby driving the dial plate to move laterally.
[0009] The present invention is further configured such that: the longitudinal moving mechanism includes a rotatable bidirectional lead screw, and each end of the bidirectional lead screw is respectively fitted with a mounting seat that can form a threaded engagement with the two ends of the bidirectional lead screw, and the dial plate is fixed to the mounting seat.
[0010] The present invention is further configured such that: a transmission rack is provided on the conveyor belt, and a transmission gear is fixedly fitted at one end of the bidirectional lead screw; the transmission gear and the transmission rack mesh with each other and can form a transmission cooperation between the two.
[0011] The present invention is further configured such that: the transverse feeding part and the longitudinal feeding part are respectively provided with a first adjusting waist hole and a second adjusting waist hole, and the transverse feeding part and the longitudinal feeding part are respectively connected with a detachable transverse extension part and a longitudinal extension part.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] Because two symmetrically arranged baffles are installed between the feeding hopper and the drying hopper, after the worker pours the rice into the feeding hopper and the feeding hopper guides the rice to the conveyor belt, the transverse and longitudinal baffles can move laterally and longitudinally respectively to push the rice horizontally and vertically, thus fully spreading the rice on the conveyor belt. This allows the rice to be spread out before the dryer dries it, facilitating thorough drying. Therefore, it effectively solves the technical problem in the prior art where piled rice blocks each other, preventing moisture from being directly exposed and affecting the drying process.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0019] like Figures 1 to 3 As shown, this utility model discloses a drying device for rice production, including a feeding hopper 1. A conveyor belt 2 is located below the feeding hopper 1. The conveyor belt 2 has an existing structure. The feeding hopper 1 guides the poured rice to the conveyor belt 2. A drying chamber 3 is located on the side of the conveyor belt 2 away from the feeding hopper 1, and the end of the conveyor belt 2 extends into the drying chamber 3. Multiple dryers 4 are installed in the drying chamber 3. These dryers 4 have existing structures, such as those using heating wires or heating lamps to dry the rice by raising the temperature, or those using fans or blowers to accelerate the airflow over the rice surface. Two symmetrically arranged baffles 5 are located above the conveyor belt 2 between the feeding hopper 1 and the drying chamber 3. Each baffle 5 consists of a transverse baffle 51 and a longitudinal baffle 52 vertically connected to form an L-shaped structure. The transverse baffle 51 is used to laterally push the piled rice, and the longitudinal baffle 52 is used to longitudinally disperse the rice. It should be noted that in this scheme, "lateral" refers to the horizontal direction parallel to the running direction of conveyor belt 2, and "longitudinal" refers to the horizontal direction perpendicular to the running direction of conveyor belt 2.
[0020] To achieve the lateral and longitudinal movement of the lever 5, guide rods 6 and rotatable one-way screws 7 are respectively provided on both sides of the conveyor belt 2. Specifically, a protruding connecting flange is provided on the frame of the conveyor belt 2. The two ends of the guide rods 6 are fixed to the corresponding connecting flanges, while the two ends of the one-way screws 7 are rotatably connected to the corresponding connecting flanges through bearings, and a drive motor 10 is connected to one side of the one-way screws 7. A connecting frame 8 is provided above the conveyor belt 2, and its two ends are slidably connected to the guide rods 6 through sliding sleeves, and threadedly engaged with the one-way screws 7 through threaded sleeves. The drive motor 10 drives the one-way screws 7 to rotate, causing the connecting frame 8 to reciprocate laterally along the guide rods 6, thereby driving the lever 5 to move laterally. In addition, a longitudinal moving mechanism is connected to the connecting frame 8, which is used to drive the lever 5 to move longitudinally.
[0021] In this embodiment, the longitudinal moving mechanism includes a rotatable bidirectional lead screw 91. Both ends of the bidirectional lead screw 91 are rotatably connected to the inner side of the connecting frame 8 via bearings. Mounting seats 92, which can form a threaded engagement with both ends of the bidirectional lead screw 91, are respectively fitted onto both ends of the bidirectional lead screw 91. The shifting plates 5 are fixed to the mounting seats 92. When the bidirectional lead screw 91 rotates, the two mounting seats 92 move along the extension direction of the bidirectional lead screw 91, thereby driving the two shifting plates 5 to move synchronously towards or away from each other, thus achieving longitudinal material shifting.
[0022] In addition, the conveyor belt 2 is equipped with a transmission rack 11. Specifically, the transmission rack 11 is fixed to the top of the frame of the conveyor belt 2, and a transmission gear 12 is fixedly fitted to one end of the double-acting screw 91. When the connecting frame 8 moves laterally back and forth along the guide rod 6, the transmission rack 11 meshes with the transmission gear 12, driving the double-acting screw 91 to rotate. This allows the lateral and longitudinal feeding of rice by the grating plate 5 to be performed simultaneously, thereby improving the leveling efficiency of the rice.
[0023] In this embodiment, a first adjusting waist hole 511 and a second adjusting waist hole 521 are respectively provided on the transverse feeding section 51 and the longitudinal feeding section 52. A detachable transverse extension section 512 and a longitudinal extension section 522 are respectively connected to the transverse feeding section 51 and the longitudinal feeding section 52. That is, the transverse extension section 512 and the longitudinal extension section 522 are detachably installed on the first adjusting waist hole 511 and the second adjusting waist hole 521 respectively by bolts. By adjusting the position of the bolts in the waist holes, the length of the feeding plate 5 can be changed, thereby adjusting the distance between the feeding plate 5 and the conveyor belt 2 to adapt to the rice feeding requirements with different moisture contents or flow rates.
[0024] When the conveyor belt 2 is running, the transmission rack 11 meshes with the transmission gear 12, driving the bidirectional lead screw 91 to rotate. This automatically matches the longitudinal movement of the deflector plate 5 with the running speed of the conveyor belt 2, preventing rice accumulation or uneven distribution due to changes in the conveyor belt 2's speed. Furthermore, the deflector plate 5 has a first adjusting waist hole 511 and a second adjusting waist hole 521 through its transverse and longitudinal adjusting sections 51 and 52, respectively. The transverse extension 512 and the longitudinal extension 522 are detachably mounted on the corresponding adjusting waist holes via bolts. By adjusting the position of the bolts within the waist holes, the length of the deflector plate 5 can be changed to accommodate rice distribution requirements with different moisture contents or flow rates.
[0025] Working process: After the worker pours the rice to be dried into the feeding hopper 1, the rice is guided to the conveyor belt 2 through the feeding hopper 1. Then, the rice is transported to the drying hopper 3 through the conveyor belt 2. During the conveying process, the baffle 5 can move horizontally and vertically at the same time to push the rice horizontally and vertically to ensure that the rice can be flattened when it enters the drying hopper 3.
[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
