Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device for large-leaf crops. Background Art

[0002] The existing large-leaf crop sorting equipment on the market has a basic structure consisting of a feeding belt line, a detection station, and several groups of independently swingable sorting belt lines. The sorting is carried out by swinging the sorting belt lines up and down. The swing of the sorting belt lines is basically driven by large-diameter cylinders on both sides.

[0003] A manual loading system is provided in front of the feeding belt line. The belt line drives the large-leaf crops through the visual inspection station, and then transports them backward through multiple sets of independently swingable grading belt lines. At the corresponding bin belt line, the grading belt line is controlled by the cylinder to swing downward, and the large-leaf crops are transported to the corresponding grading station. The belt line is then swung straight by the cylinder to transport the subsequent large-leaf crops forward for subsequent grading actions.

[0004] In the existing feeding belt line structure, the belt moves along the upper surface of the belt tray. To ensure conveying efficiency, this structure can only convey single large-leaf crops, resulting in poor conveying efficiency. In addition, large-leaf crops are easily stuck in the gap between the belt and the tray, causing damage or curling of the large-leaf crops, which is not conducive to subsequent visual inspection.

[0035] like Figures 1 to 7 The illustrated large-leaf crop conveyor device is used to convey single or multiple large-leaf crops. It includes a conveyor frame 13 and a conveyor belt 3. Multiple supports 22 are vertically mounted on the conveyor frame 13. Mounted on the upper and lower surfaces of the supports 22 are upper and lower belt supports 1 and 2, respectively, supporting the conveyor belt 3. Four upper and lower belt supports 1 and 2 are provided, respectively. The conveyor belt 3 is connected to a power assembly. A material storage table is located above one end of the conveyor frame 13. Several scraper blades 4 are evenly spaced on the conveyor belt 3. Each adjacent scraper blade 4 forms a barrier, within which a single or multiple large-leaf crops are placed. The scraper blades 4 are positioned perpendicular to the conveyor belt 3. A chute 14 is defined on the upper belt support 1. Each end of the scraper blade 4 has protrusions 21 extending into the chute 14. The protrusions 21 extend beyond the conveyor belt 3. The protrusions 21 travel along the chute 14, preventing the large-leaf crops from becoming stuck in the gap between the belt and the support.

[0036] The scraping blade 4 is in the shape of a Chinese character 'Shan' (mountain), and at the midpoint of the lower part of the scraping blade 4, there is an installation part 16 installed on the conveyor belt 3.

[0037] A channel 15 is formed between two adjacent upper belt support plates 1. The conveyor belt 3 is located above the channel 15, and the two longitudinal edges of the conveyor belt 3 are laid on the upper belt support plates 1.

[0038] The lower belt support plate 2 includes two relatively arranged L-shaped lower support plate bodies 23. A conveying channel for the conveyor belt 3 to travel is formed between the two lower support plate bodies 23, and the two longitudinal edges of the conveyor belt 3 are laid on the horizontal plates of the lower support plate bodies 23.

[0039] A plurality of limiting bumps 8 are horizontally arranged along the width direction on the back of the conveyor belt 3. The limiting bumps 8 are embedded in the channel 15, which can prevent the conveyor belt 3 from running off track.

[0040] The feeding end and the discharging end of the upper belt support plate 1 are respectively provided with inclined surfaces 17 for facilitating the conveyor belt 3 to give way. The two inclined surfaces 17 are distributed in a 'V' shape.

[0041] The power assembly includes a driving wheel 5, a driven wheel 9 and a motor 7. The driving wheel 5 and the driven wheel 9 are respectively located at both ends of the conveyor belt 3. A driving shaft 6 is provided at the center of the driving wheel 5; the driving shaft 6 is connected to the output shaft of the motor 7, and the driving wheel 5 is arranged close to the storage workbench.

[0042] Several groups of turning and guiding assemblies for transferring the upper-layer large-leaf crops to the lower layer are installed on the conveyor frame 13. The turning and guiding assemblies are arranged away from the storage workbench. The distance between two adjacent groups of turning and guiding assemblies is equal. The conveyor belt 3 passes through the interval between the turning and guiding assemblies; the turning and guiding assemblies include an inner turning and guiding member 11 and an outer turning and guiding member 10 which are distributed inside and outside. The inner turning and guiding member 11 includes a horizontal section 18, a lifting section 19 and an arc section 20 which are connected in sequence. The horizontal section 18 is connected to the discharging end of the upper belt support plate 1; the outer turning and guiding member 10 is an arc-shaped guiding member; an attitude adjusting blade 12 is installed on the inner wall of the outer turning and guiding member 10, and the other end of the attitude adjusting blade 12 can be in contact with and abuts against the outer wall of the inner turning and guiding member 11 or the outer wall of the conveyor belt 3; the attitude adjusting blade 12 is an elastic blade arched upwards.

[0043] The working process of this large-leaf crop conveying device is specifically as follows: A partition is formed between two adjacent scraping blades 4 before and after. One or more large-leaf crops are placed in a partition; the power assembly works to drive the conveyor belt 3 to work, and convey one or more large-leaf crops to the subsequent workstations.

[0044] This large-leaf crop conveying device has a simple structure and is easy to operate, and has the following advantages:

[0045] It should be noted that in the original text, the description of the inclined surface 17 in is incorrect. It should be '呈“八”字状分布' instead of '呈“V”字状分布'. The above translation has been corrected according to the correct content.(1) A plurality of scraper blades 4 are arranged at equal intervals on the conveyor belt 3. A barrier is formed between two adjacent scraper blades 4. A single or multiple large-leaf crops are placed in a barrier to prevent the large-leaf crops from piling up together. This allows for better control of the front and rear spacing and posture of the large-leaf crops, which is beneficial for subsequent visual inspection.

[0046] (2) A chute 14 is provided on the upper support plate 1 of the belt, and protrusions 21 extending into the chute 14 are provided at both ends of the lower portion of the scraper paddle 4. The protrusions 21 move along the chute 14, which can avoid problems such as large-leaf crops getting stuck in the gap between the belt and the support plate;

[0047] (3) The posture adjustment paddle 12 is an elastic paddle that is arched upward. During the process of guiding the large-leaf crops by the inner turning guide 11 and the outer turning guide 10, the posture adjustment paddle 12 can press against the large-leaf crops to control the front and rear spacing and posture of the large-leaf crops, which is beneficial to the subsequent bin separation work;

[0048] (4) The utility model operates smoothly and has high conveying efficiency.

[0049] The above description only describes the specific implementation methods of the utility model. Various examples do not limit the essential content of the utility model. Ordinary technicians in the relevant technical field can make modifications or deformations to the specific implementation methods described above after reading the description without departing from the essence and scope of the utility model.
