Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, specifically to a rice conveying device. Background Technology

[0002] Fried rice is a common food, made by stir-frying cooked rice, some vegetables, and eggs. Rice is the most frequently used ingredient in fried rice. In today's highly competitive catering market, the key to market dominance lies in accelerating cooking speed while improving the quality and taste of fried rice. Autonomous cooking equipment, such as cooking robots, has emerged to address this need.

[0003] Rice is sticky and easily adheres to utensils, making it difficult to transport. Existing technology uses a spiral feeding mechanism, such as the Chinese patent publication CN221520967U, which discloses a rice conveying device for a cooking robot, employing a spiral conveyor to automatically transport rice. However, this rice conveying structure has high requirements for the rice; it must not be too sticky, otherwise it will easily adhere to the conveying spiral and prevent transport. In other words, the requirements for rice in existing spiral conveying rice conveying devices limit their applicability. Therefore, it is necessary to develop a new type of rice conveying device to solve these problems. Utility Model Content

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0031] One embodiment of this utility model is a rice conveying device, see [link to relevant documentation]. Figures 1 to 6The system mainly includes a rice container 10, a belt conveyor mechanism 20, and a scraping component 30. The rice container 10 has a cavity and a discharge port 112 at its bottom. The belt conveyor mechanism 20 is horizontally positioned at the bottom of the cavity within the rice container 10, with its left end located above the discharge port 112 (specifically, above the right side). Since the rice falls in a parabolic trajectory under the belt 22, the left end of the belt conveyor mechanism 20 should be positioned above the right side of the discharge port 112. In this embodiment, the projection of the right end of the belt conveyor mechanism 20 onto the bottom surface of the rice container 10 partially falls onto the discharge port 112. The scraping component 30 is located on the bottom surface of the rice container 10, next to the discharge port 112, and close to the belt conveyor mechanism 20 to scrape off rice adhering to the outer surface of the belt conveyor mechanism 20. The device has no requirements regarding the viscosity of the rice, which greatly expands its application scenarios. It has a simple structure and is highly practical.

[0032] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the rice container 10 is an L-shaped cubic box 11, shorter at the top and longer at the bottom, and hollow inside to form a cavity. The top opening forms a rice inlet 111. The bottom end is specifically as shown... Figure 4 The left end opening shown forms a feeding port 112. Below the feeding port 112 is a receiving box 200 that connects to the rice conveying device 100. The belt conveyor mechanism 20 conveys rice scraped off by the scraping mechanism, which falls into the receiving box 200. According to some preferred embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the rice container 10 of this utility model has an opening on the front, and an openable and closable door panel 12 is provided at the opening. That is, the rice container 10 includes a container body 11 with openings on both the front and top, and an openable and closable door panel 12 located at the opening on the front of the container body 11. Specifically, one end of the door panel 12 is, for example, as shown in the diagram. Figure 1 The right end shown is hinged to the box 11 via a hinge on the right front edge plate of the box 11, and the other end of the door panel 12 is, for example, Figure 1 The left end shown is connected by screws, such as wing screws, on the left front edge plate of the box 11. According to some preferred embodiments of the present invention, the door panel 12 is a conventional transparent PC board, which allows the operator to easily observe the state of the rice on the belt conveyor mechanism 20 inside the rice box 10 during use.

[0033] like Figure 2 and Figure 3As shown, the belt conveyor mechanism 20 includes a drive mechanism 21, a mounting structure, and a belt 22. The drive mechanism 21 includes an electric roller 211 and a non-powered roller 212. In this embodiment, the electric roller 211 is a waterproof electric roller 211, and its power cord (not shown) is connected to an external power source (not shown) through a wiring hole (not shown) on the transparent door panel 12. The mounting structure includes two components arranged as shown in the diagram. Figure 2 or Figure 3 The front-to-back support 23 shown in this embodiment of the invention consists of two plate-shaped supports 23 that extend along the transmission direction of the belt conveyor mechanism 20. Figure 3 The sheet metal bracket 23 extends in the left-right direction as shown. The electric roller 211 and the non-powered roller 212 are respectively installed at both ends of the two sheet metal brackets along the transmission direction of the belt conveyor mechanism 20, i.e., as shown... Figure 3 The left and right ends are shown. The belt 22 is wound around the electric roller 211 and the non-powered roller 212 to transmit power relative to the electric roller 211 and the non-powered roller 212 around their axes under the drive of the electric roller 211. In this embodiment of the invention, the belt 22 includes a ring-shaped body 221 and a plurality of partition protrusions 222 formed on the outer circumferential surface of the body 221 and spaced apart circumferentially along the body 221. Each partition protrusion 222 extends outward along the radial direction of the body 221. Each partition protrusion 222 is made of a conventional flexible material available on the market, and is not specifically described or limited. It should be noted that the belt 22 in this embodiment of the invention is made of a conventional food-grade material available on the market, and is not specifically described or limited, as those skilled in the art will readily understand. In a preferred embodiment, the partition protrusions 222 and the body 221 are an integral structure made of the same material. As an alternative embodiment, the partition protrusion 222 and the body 221 are separate structures made of different materials, and can be connected by adhesive bonding or a snap-fit ​​structure with matching protrusions and slots. The length of the partition protrusion 222 is the same as the width of the belt 22 body 221, and its height is not specifically described or limited, but should be slightly lower than the distance between the lower surface of the belt conveyor mechanism 20 and the bottom surface of the rice container 10. The interval between any two partition protrusions 222 forms a partition space. In this embodiment of the invention, the electric roller 211 is located as follows... Figure 3 As shown on the left end, the unpowered roller 212 is located as follows Figure 3As shown on the right end, during operation, the belt conveyor mechanism 20 rotates counterclockwise. Rice falls from the feed inlet 111 at the top of the rice container 10 into the partition space of the belt conveyor mechanism 20. As the belt 22 rotates, the rice is propelled forward by the partition protrusions 222. When the rice reaches the end of the belt 22, it falls from the discharge port 112 into the receiving box 200 below under gravity. Due to the scraping component 30 at the lower end of the belt 22, the scraping component 30 contacts the outer surface of the belt 22 body 221, scraping off the rice adhering to the outer surface of the body 221, and then falls into the receiving box 200 through the discharge port 112. The partition protrusions 222 on the belt 22 are made of flexible material and can deform to pass through the scraping component 30. After the partition protrusions 222 scrape past the scraping component 30, the belt 22 is completely separated from the rice. Figure 6 As shown, in this embodiment of the present invention, the rice conveying device 100 and the connecting box 200 are both mounted on a frame 300. The rice conveying device 100 is located at the upper end of the frame 300, and the connecting box 200 is located at the lower left end of the frame 300, and the connecting box 200 is located directly below the feed inlet 112 of the rice conveying device 100.

[0034] In this embodiment of the invention, the belt conveyor mechanism 20 is detachably connected to the rice container 10. Specifically, as shown... Figure 3 and Figure 4 As shown, in order to achieve a detachable connection between the belt conveyor mechanism 20 and the rice container 10, two [devices] are provided on the inner wall of the rice container 10 along the transmission direction of the belt conveyor mechanism 20, i.e., [the following is an example of a detachable connection]. Figure 4 The positioning members 113 shown are arranged in a parallel and opposite direction in the left and right directions, with any one of the positioning members 113 facing the front of the rice box 10. Figure 4 The front protrusion shown is such that each positioning element 113 can be selected from existing conventional angle steel and is fixed to the rice container 10 by welding. Correspondingly, as... Figure 3 As shown, the two sheet metal brackets 23 of the belt conveyor mechanism 20 have corresponding positioning holes 231 that correspond one-to-one with the two positioning parts 113, that is, each positioning hole 231 is L-shaped. The belt conveyor mechanism 20 is connected to the positioning parts 113 through the positioning holes 231, which allows for quick assembly and disassembly; the detachable connection makes it easy to disassemble the belt conveyor mechanism 20 for cleaning after use. When cleaning, first disconnect the power cord of the electric roller 211, then open the transparent door panel 12 and pull the belt conveyor mechanism 20 out of the positioning sheet metal inside the rice box 10. The belt conveyor mechanism 20 is separated from the rice box 10, which makes cleaning convenient.

[0035] For the scraper component 30, such as Figure 4 and Figure 5As shown, in this embodiment of the invention, the scraping component 30 is located on the right side of the discharge port 112 and extends upward to elastically contact the lower surface of the body 221 of the belt conveyor mechanism 20. Preferably, to prevent the scraping component 30 from scratching the belt 22, the top end of the scraping component 30 is provided with an arc surface 33. More specifically, as shown... Figure 5 As shown, the scraping mechanism of this utility model embodiment is integrally formed with the bottom end face of the rice box 10. That is, after the left side of the bottom end face of the rice box 10 is folded upward, the upper part is folded downward to form two folded edges that fit together. For ease of description, the two folded edges are respectively described as an upwardly extending first folded edge 31 and a downwardly extending second folded edge 32. The first folded edge 31 and the second folded edge 32 form an arc edge, and the outer surface of the arc edge is the arc surface 33. Thus, a notch, i.e., a feeding port 112, is formed on the left side of the bottom end of the rice box 10. At the same time, the upper end face of the scraping component 30 is formed as an arc surface 33, which can effectively protect the belt 22 from being scratched by the scraping component 30 and improve the service life of the belt 22. It should be noted that the scraping component 30 of this utility model embodiment is close to the outer surface of the belt 22. Preferably, it is in direct contact. Alternatively, it may not be in contact, but has a very small, negligible gap of a few millimeters. This can reduce the frictional resistance between the belt conveyor 20 and the scraping mechanism during transmission and can also scrape off the rice adhering to the outer surface of the belt 22.

[0036] The rice conveying device 100 of this embodiment uses a belt conveyor mechanism 20 to convey rice. There is no limitation on the viscosity of the rice. During transmission, the rice will detach from the belt 22 under gravity and fall from the discharge port 112 onto the bottom receiving box 200. Simultaneously, a scraper component 30 can scrape off the rice adhering to the outer surface of the belt 22, separating the rice from the belt 22 and causing it to fall from the discharge port 112 onto the bottom receiving box 200. When the rice falls onto the belt 22 through the feed port 111, the partition protrusions 222 on the belt 22 push the rice forward under the drive of the belt 22. The partition protrusions 222 are made of flexible material and can deform to pass through the scraper component 30. The belt conveyor mechanism 20 is detachably connected to the rice conveying device, facilitating subsequent cleaning of the belt 22. The door panel 12 is a transparent panel, allowing the operator to observe the state of the rice on the belt conveyor mechanism 20 inside the rice box 10 during operation.

[0037] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
