Description

Technical Field

[0001] This utility model relates to a conveying device in a rice production line. Background Technology

[0002] Rice, also known as paddy rice or rice paddy, is an edible grain. In rice production lines, the conveying of rice requires selecting appropriate equipment based on the characteristics of different stages. The core objectives are to reduce material breakage, avoid contamination, and ensure conveying efficiency. Chinese Patent Application No. 202310977283.4 discloses a conveying device for rice processing, including a housing, a conveyor head, and a feeding assembly. This conveying device, through the coordinated arrangement of the conveyor head and the swinging assembly, can drive the conveyor head to swing laterally back and forth within the housing under the drive of a spiral spring auger, preventing blockages caused by excessive rice accumulation. Furthermore, through the coordinated arrangement of the feeding assembly and the sliding drive assembly, the device can drive the pusher plate to extend, retract, and rotate during the movement of the conveyor head, thus moving the rice around the conveyor head into the feeding hopper, facilitating the conveyor head's transport of the rice without the need for continuous manual feeding into the hopper. However, it still has the following shortcomings: the conveying equipment is not easy to move. When the rice in a local area of ​​the grain pile is exhausted, it is not convenient to move the conveying equipment to retrieve grain from other areas of the grain pile. It is still necessary to manually move the surrounding rice to the vicinity of the grain retrieval port with the help of external tools, which not only increases the intensity of manual labor, but also leads to a significant decrease in grain retrieval efficiency. Utility Model Content

[0003] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0004] Another objective of this invention is to provide a conveying device for a rice production line, which can conveniently move the conveying components to a suitable position in the grain pile via a vehicle body for grain retrieval, effectively improving conveying efficiency and saving manpower.

[0005] To achieve these objectives and other advantages according to the present invention, a conveying device for a rice production line is provided, comprising: a vehicle body; a shovel plate, the rear end of which is hinged to the front end of the vehicle body; and a conveying assembly including a conveying hose, the feed end of which is detachably extended axially onto the vehicle body, and the inlet of the feed end is positioned above the shovel plate; a helical spring auger extending within the conveying hose, one end of which extends out of the inlet; a feed inlet formed on the wall of the feed end of the conveying hose, facing upwards towards the vehicle body; a pair of slots correspondingly disposed on both sides of the feed inlet on the vehicle body; a pair of shafts extending symmetrically along the axial direction of the vehicle body onto the pair of slots, both shafts being rotatably disposed towards the feed inlet; and a plurality of conveying blades evenly distributed on the pair of shafts.

[0006] Preferably, the tilt angle of the shovel plate relative to the plane of the vehicle body is less than or equal to 30°.

[0007] Preferably, the multiple conveying blades on either of the pair of shafts further include: a spiral conveying blade disposed on a portion of the shaft near the front end of the vehicle body; and multiple rectangular blades evenly spaced apart on a portion of the shaft near the rear end of the vehicle body; and in the axial direction, the length of the spiral conveying blade is less than the total length of the multiple rectangular blades.

[0008] Preferably, it further includes: a reinforcing member disposed on the vehicle body, and the reinforcing member is disposed at one end of a pair of slots; the reinforcing member includes a pair of arc-shaped pieces, one end of which is respectively hinged to the vehicle body, the other end of the pair of arc-shaped pieces is detachably connected by bolts, and the fastener is detachably fastened to the delivery hose.

[0009] Preferably, it also includes: a baffle, which is disposed at the rear end of the vehicle body; a locking hole, which is formed on the baffle; and a tray, which extends from the locking hole to the rear end of the vehicle body, wherein the delivery hose is detachably placed in the locking hole and the tray.

[0010] Preferably, it also includes: a pair of guide plates, which are symmetrically arranged below a pair of shafts on both sides of the vehicle body, and the pair of guide plates are inclined toward the feed inlet side, and each guide plate does not contact the multiple conveying blades on any adjacent shaft.

[0011] This utility model has at least the following beneficial effects:

[0012] A shovel is installed at the front of the vehicle body. On the one hand, the shovel can actively shovel into the surface or deep layer of the grain pile by the forward thrust of the vehicle body when it moves, loosening and peeling the compacted grain pile before guiding it to the opening of the conveying hose, thus avoiding the spiral spring auger from spinning idly due to insufficient feeding. On the other hand, the rice slowly slides into the opening of the hose through the inclined surface of the shovel, replacing the direct falling method, reducing the impact force between the rice and the equipment. This is especially effective in reducing the breakage rate when conveying fragile brown rice and polished rice.

[0013] A pair of slots are provided to effectively lock and protect the feed end of the conveying hose, preventing it from being damaged or deformed by squeezing, keeping the feed flow through the hose unobstructed and avoiding blockages.

[0014] Multiple conveying blades are set up to cooperate with a pair of shafts, so that the rice sliding to both sides of the vehicle body slides evenly into the feed inlet, thereby improving the conveying efficiency.

[0015] In summary, the conveying device in the rice production line provided by this utility model can conveniently move the conveying components to a suitable position in the grain pile for grain retrieval by means of a vehicle body, effectively improving conveying efficiency and saving manpower.

[0016] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0026] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0027] like Figures 1-3As shown, this utility model provides a conveying device in a rice production line, comprising: a vehicle body 1, which can be equipped with both casters and drive wheels. The drive wheels are directly driven by a DC servo motor, and the forward and backward movement of the vehicle is controlled by the forward and reverse rotation of the motor, which, in conjunction with the casters, enables steering; or, multiple sets of casters and a push handle are provided, allowing the vehicle body to be moved to a suitable position for grain picking under manual drive; a shovel plate 2, the rear end of which is hinged to the front end of the vehicle body; during the movement of the vehicle body, the shovel plate can easily insert the vehicle body into the grain pile, and cause the rice at the front end of the shovel plate to move to the opening of the conveying hose, and then efficiently and without blockage is conveyed to the next process through the conveying hose; and a conveying assembly 3, which includes a conveying hose 301, the feed end of which can be... The axial extension of the disassembled part is installed on the vehicle body, and the inlet of the feed end is positioned above the shovel plate. The conveying hose is usually made of food-grade steel wire reinforced PU hose. A spiral spring auger 302 extends inside the conveying hose, with one end of the spiral spring auger extending out of the inlet 3011. The other end of the spiral spring auger is driven to rotate by the motor of the hose conveyor. The feed inlet 3012 is opened on the wall of the feed end of the conveying hose, and the feed inlet is positioned facing upwards on the vehicle body. A pair of slots 303 are correspondingly installed on the vehicle body on both sides of the feed inlet. A pair of shafts 304 extend symmetrically along the axial direction of the vehicle body on the pair of slots, and both shafts are rotated towards the feed inlet. Multiple conveying blades 305 are evenly distributed on the pair of shafts. In this design, a shovel is installed at the front of the vehicle body. On one hand, the shovel can actively scoop into the surface or deep layers of the grain pile using the forward thrust of the vehicle's movement, pre-loosening and peeling the compacted grain before guiding it to the inlet of the conveying hose, thus preventing the spiral spring auger from spinning idly due to insufficient feed. On the other hand, the rice slowly slides into the inlet through the inclined surface of the shovel, replacing the direct drop method, reducing the impact force between the rice and the equipment. This is especially effective in reducing the breakage rate when conveying fragile brown rice and polished rice. A pair of slots are provided to effectively lock and protect the feed end of the conveying hose, preventing damage or deformation and keeping the grain conveying at the inlet unobstructed. Multiple conveying blades are installed in conjunction with a pair of shafts to ensure that the rice sliding to both sides of the vehicle body slides evenly into the feed inlet, improving conveying efficiency.

[0028] In summary, the conveying device in the rice production line provided by this utility model can conveniently move the conveying components to a suitable position in the grain pile for grain retrieval by means of a vehicle body, effectively improving conveying efficiency and saving manpower.

[0029] In a preferred embodiment, the tilt angle of the shovel relative to the plane of the vehicle body is less than or equal to 30°, such as 0°, 5°, 15°, or 30°. In this embodiment, when not retrieving grain, the shovel can be raised to the same plane as the vehicle body for easy movement and storage. During grain retrieval, when the grain pile is high, the shovel does not need adjustment and remains horizontal, allowing for rapid shoveling of the surface layer of rice. As the grain pile gradually decreases in height, the shovel can be tilted downwards to scoop the remaining rice close to the ground until reaching the bottom of the pile, significantly reducing the frequency of manual refueling or equipment adjustments and increasing continuous operation time. In practical applications, hydraulic rods or electric push rods can be installed to support the shovel for convenient adjustment of its angle.

[0030] like Figure 4 As shown, in a preferred embodiment, the multiple conveying blades on either shaft of a pair of shafts further include: a spiral conveying blade 3051, which is disposed on the portion of the shaft near the front end of the vehicle body; and multiple rectangular blades 3052, which are evenly spaced and distributed on the portion of the shaft near the rear end of the vehicle body; and in the axial direction, the length of the spiral conveying blade is less than the total length of the multiple rectangular blades. In this embodiment, the spiral conveying blade is used to loosen the rice in the grain pile and convey it backward, while the multiple rectangular blades located at the rear can continuously convey the conveyed rice to the feed inlet; thereby realizing simultaneous feeding at the front pipe opening and the upward-facing feed inlet, thus splitting the rice flow originally concentrated at the pipe opening into two paths, reducing the instantaneous feeding pressure at the pipe opening, and effectively preventing the rice from clogging the conveying hose due to compression and agglomeration at the pipe opening; in addition, simultaneous feeding at the pipe opening and the feed inlet significantly increases the material acceptance per unit time, and combined with the forced conveying capacity of the spiral auger, the overall conveying efficiency can be significantly improved, especially suitable for the "continuous large-flow grain intake" requirement in large-scale processing.

[0031] like Figure 5 As shown, in a preferred embodiment, it further includes: a reinforcing member 306, which is disposed on the vehicle body and located at one end of a pair of slots; the reinforcing member includes a pair of arc-shaped pieces, one end of which is hinged to the vehicle body, and the other end of the pair of arc-shaped pieces is detachably connected by bolts, and the fastener is detachably fastened to the conveying hose. In this embodiment, the reinforcing member is used to assist in reinforcing the conveying hose, which has a simple structure and is easy to use.

[0032] like Figure 6 , 7As shown, a preferred embodiment further includes: a baffle 307 disposed at the rear end of the vehicle body; a locking hole 3071 formed on the baffle; and a support groove 308 extending from the locking hole towards the rear end of the vehicle body, wherein the conveying hose is detachably placed within the locking hole and the support groove. In this embodiment, the baffle is used to assist in shielding the rice grains, preventing excessive movement of the rice grains to the rear of the vehicle body; the support groove and locking hole are used to support and protect the conveying hose, preventing excessive bending of the conveying hose during vehicle movement.

[0033] like Figure 8 As shown, in a preferred embodiment, it further includes: a pair of guide plates 309, symmetrically arranged below a pair of shafts on both sides of the vehicle body, and the pair of guide plates are inclined towards the feed inlet side, with each guide plate not contacting the multiple conveying blades on any adjacent shaft. In this embodiment, a pair of guide plates is provided to guide the rice sliding down from the multiple conveying blades into the feed inlet, thereby improving conveying efficiency.

[0034] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
