Technical Field

[0001] This utility model relates to the field of fruit sorting technology, specifically to a circular belt conveyor for removing small fruits. Background Technology

[0002] Existing technologies for removing small fruits are inefficient and lack fruit protection, resulting in packaging efficiency and stability that fail to meet market demands for fresh fruits with short shelf lives. Manual packaging, on the other hand, requires significant labor costs and is inefficient, greatly reducing the economic benefits and user experience for customers. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a circular belt conveyor for removing small fruits. This mechanism can quickly sort small fruits, improve sorting efficiency, and transport and classify the sorted small fruits separately.

[0004] The technical solution of this utility model is: a circular belt conveyor for removing small fruits, including a workbench, on which a removal mechanism and a conveying mechanism are provided;

[0005] The rejection mechanism includes a support frame, which has a driving roller assembly and a driven roller assembly. The driving roller assembly has multiple main drive pulleys, and the driven roller assembly has multiple driven pulleys. The main drive pulleys and driven pulleys cooperate with each other and are connected by a circular belt.

[0006] The support frame is also provided with a drive component that drives the active roller assembly to rotate. The drive component drives the circular belt to rotate through the active roller assembly in order to transport the small fruits placed on the circular belt.

[0007] The conveying mechanism includes a transverse conveyor belt disposed on the support frame and a drive motor that drives the transverse conveyor belt to rotate. The drive motor drives the transverse conveyor belt to rotate so as to convey small fruits that fall from the gaps in the round belt onto the transverse conveyor belt.

[0008] Furthermore, the support frame includes a left side plate, a right side plate, and an intermediate connecting plate disposed between the left side plate and the right side plate. The active roller assembly and the driven roller assembly are both disposed between the left side plate and the right side plate and are located above the intermediate connecting plate.

[0009] Furthermore, both the left and right side plates are provided with openings, one end of the transverse conveyor belt extends from the opening in the left side plate, and the other end of the transverse conveyor belt extends from the opening in the right side plate.

[0010] Furthermore, the intermediate connecting plate is configured with a stepped structure and includes a first step and a second step, wherein the first step is an inclined surface and the second step is a plane; the transverse conveyor belt is located above the second step, and the upper end surface of the transverse conveyor belt is lower than the inclined surface of the first step.

[0011] Furthermore, a lower tension roller assembly located below the intermediate connecting plate is provided between the left and right side plates. The lower tension roller assembly is used to detachably assemble the circular belt onto the driving roller assembly and the driven roller assembly between the left and right side plates.

[0012] Furthermore, the lower tension roller assembly includes a tension shaft and bearings located at both ends of the tension shaft. The two ends of the tension shaft pass through the left side plate and the right side plate respectively and are connected to the bearings. The bearings are connected to the left side plate and the right side plate respectively by bolts.

[0013] Furthermore, both the left and right side plates are provided with limiting grooves for use with the tensioning shaft, and the opposite sides of the limiting grooves are provided with limiting locking grooves for use with the bearing.

[0014] Furthermore, the workbench is equipped with wheels at its bottom.

[0015] Furthermore, an intermediate support shaft located in the support frame is provided between the active roller assembly and the driven roller assembly, and the intermediate support shaft is provided with an intermediate pulley for use with the circular belt.

[0016] Furthermore, an inclined guide plate is provided on the outer side of the active roller assembly.

[0017] The beneficial technical effects of this utility model are:

[0018] 1. Small fruits that meet the size requirements are transported by a circular conveyor belt, while smaller fruits that fall from the gap between the two circular conveyor belts are transported by a transverse conveyor belt. The two sets of transportation methods are used to quickly sort the small fruits.

[0019] 2. Adjust the tension of the circular belt through the intermediate support shaft so that the circular belt can be detachably fitted onto the intermediate pulley, the main drive pulley, and the driven pulley. With the detachable setting of the circular belt, the personnel can adjust the distance between the two circular belts according to the required size of the small fruit to complete the sorting of the small fruit.

[0020] 3. The intermediate connecting plate facilitates the collection of small fruits that do not meet the size requirements. During the transportation of small fruits on the circular belt, they fall directly onto the transverse conveyor belt, or slide onto the transverse conveyor belt using the inclined surface of the first step of the intermediate connecting plate, reducing the cushioning force of the falling small fruits and preventing damage to them.

[0021] 4. The intermediate support shaft further supports the circular belt.

[0022] 5. The workbench is equipped with casters at the bottom, which facilitates the movement of the equipment and allows for quick connection to the required equipment line.

[0023] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0033] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

They are only for the convenience of describing this utility model and 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. Therefore, they should not be construed as limitations on this utility model.

[0036] like Figures 1-7 As shown, this utility model specifically relates to a circular belt 170 conveyor for removing small fruits, including a workbench 300, on which a removal mechanism 100 and a conveying mechanism 200 are provided;

[0037] The rejection mechanism 100 includes a support frame 110, which has a drive roller assembly 120 and a driven roller assembly 140. The drive roller assembly 120 has a plurality of main drive pulleys 122, and the driven roller assembly 140 has a plurality of driven pulleys. The main drive pulleys 122 and the driven pulleys cooperate with each other and are connected by a circular belt 170.

[0038] The support frame 110 is also provided with a drive assembly 130 for driving the active roller assembly 120 to rotate. The drive assembly 130 drives the circular belt 170 to rotate through the active roller assembly 120, so as to transport the small fruits placed on the circular belt 170.

[0039] The conveying mechanism 200 includes a transverse conveying mesh chain 210 disposed on the support frame 110 and a drive motor 220 for driving the transverse conveying mesh chain 210 to rotate. The drive motor 220 drives the transverse conveying mesh chain 210 to rotate so as to convey small fruits that fall from the gaps in the round belt 170 onto the transverse conveying mesh chain 210.

[0040] It should be noted that the active roller assembly 120 is located at one end of the support frame 110, and the driven roller assembly 140 is located at the other end of the support frame 110. The active roller assembly 120 and the driven roller assembly 140 are arranged in parallel.

[0041] Additionally, the driving roller assembly 120 includes a main drive shaft 121 and a main drive pulley 122 disposed on the surface of the main drive shaft 121; the driven roller assembly 140 includes a driven roller (not shown in the figure) and a driven pulley disposed on the surface of the driven roller, and a circular belt 170 is sleeved on the main drive pulley 122 and the driven pulley.

[0042] Furthermore, when the drive assembly 130 drives the main drive shaft 121 to rotate, it drives the driven roller assembly 140 to rotate via the circular belt 170, thereby completing the transport of the small fruits placed on the circular belt 170.

[0043] The drive assembly 130 is a structure capable of driving the main drive shaft 121 to rotate. In this embodiment, a reducer 131 and a torque arm 132 are used in conjunction. The torque arm 132 is connected to the main drive shaft 121, and the reducer 131 drives the main drive shaft to rotate through the torque arm 132. This is a relatively mature structure in the prior art, so it will not be described in detail.

[0044] The number of main drive pulleys 122 is the same as the number of driven pulleys (not shown in the figure). Similarly, the number of round belts 170 is also the same. Personnel can adjust the gap between the two round belts 170 by increasing or decreasing the number of round belts 170, thereby sorting small fruits of different sizes.

[0045] Since the transverse conveyor belt 210 is located on the support frame 110, when small fruits fall onto the transverse conveyor belt 210 through the gap between the two circular belts 170, the drive motor 220 drives the transverse conveyor belt 210 to rotate, so as to transport the small fruits.

[0046] By using two sets of transportation methods—circular belt 170 and transverse conveyor belt 210—small fruits are sorted and transported in categories, thus improving sorting efficiency.

[0047] The support frame 110 includes a left side plate 111, a right side plate 112, and an intermediate connecting plate 113 disposed between the left side plate 111 and the right side plate 112. The active roller assembly 120 and the driven roller assembly 140 are both disposed between the left side plate 111 and the right side plate 112, and are located above the intermediate connecting plate 113.

[0048] Both the left side plate 111 and the right side plate 112 are provided with openings 1121. One end of the transverse conveyor belt 210 extends out from the opening 1121 of the left side plate 111, and the other end of the transverse conveyor belt 210 extends out from the opening 1121 of the right side plate 112.

[0049] The length of the transverse conveyor belt 210 is greater than the length of the support frame 110. By setting the transverse conveyor belt 210 below the transport surface of the circular belt 170, small fruits can easily fall onto the transverse conveyor belt 210 through the gap between the two circular belts 170, so as to transport the small fruits.

[0050] The intermediate connecting plate 113 is configured with a stepped structure and includes a first step 1131 and a second step 1132. The first step 1131 is an inclined surface, and the second step 1132 is a plane. The transverse conveyor belt 210 is located above the second step 1132, and the upper end surface of the transverse conveyor belt 210 is lower than the inclined surface of the first step 1131.

[0051] The bottom of the transverse conveyor belt 210 is in contact with the plane of the second step 1132, and the upper surface of the transverse conveyor belt 210 is lower than the inclined surface of the first step 1131. During the transportation of small fruits on the round belts 170, they fall directly onto the transverse conveyor belt 210 through the gaps between the round belts 170, or slide onto the transverse conveyor belt 210 through the inclined surface of the first step 1131, reducing the loss rate of small fruits falling.

[0052] A lower tension roller assembly 160 is also provided between the left side plate 111 and the right side plate 112, located below the intermediate connecting plate 113. The lower tension roller assembly 160 is used to detachably assemble the circular belt 170 onto the driving roller assembly 120 and the driven roller assembly 140 between the left side plate 111 and the right side plate 112.

[0053] The circular belt 170 is respectively fitted onto the driving roller assembly 120, the driven roller assembly 140 and the lower tension roller assembly 160. The tension of the circular belt 170 is adjusted by the lower tension roller assembly 160 in order to complete the fixing and disassembly of the circular belt 170.

[0054] The lower tensioning roller assembly 160 includes a tensioning shaft 161 and bearings 162 located at both ends of the tensioning shaft 161. The two ends of the tensioning shaft 161 pass through the left side plate 111 and the right side plate 112 respectively and are connected to the bearings 162. The bearings 162 are connected to the left side plate 111 and the right side plate 112 respectively by bolts.

[0055] Both the left side plate 111 and the right side plate 112 are provided with limiting grooves 1112 for use with the tensioning shaft 161, and the opposite sides of the limiting grooves 1112 are provided with limiting locking grooves 1111 for use with the bearing 162.

[0056] When the tensioning shaft 161 is at the highest position of the limiting groove 1112, the round belt 170 is in a relaxed state, and personnel can disassemble or install the round belt 170. When the tensioning shaft 161 is at the lowest position of the limiting groove 1112, the round belt 170 is in a taut state. At this time, the round belt 170 is fixed and can rotate through the main drive shaft 121 to complete the transportation of small fruits.

[0057] During this process, the tensioning shaft 161 is adjusted by adjusting the bolts fixing the bearing 162.

[0058] The workbench 300 is equipped with casters 400 at the bottom, which facilitates the movement of the equipment and allows it to be quickly connected to the required equipment line.

[0059] An intermediate support shaft 150 is also provided between the driving roller assembly 120 and the driven roller assembly 140, located on the support frame 110. The intermediate support shaft 150 is provided with an intermediate pulley for use with the circular belt 170, further supporting the circular belt 170.

[0060] Furthermore, an inclined guide plate 180 is provided on the outer side of the active roller assembly 120 to facilitate the transportation of small fruits that meet the size requirements after screening, thereby reducing the damage rate of small fruits.

[0061] The above embodiments are merely specific implementations of this utility model, used to illustrate the technical solutions of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features within the technical scope disclosed in this utility model. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be covered within the protection scope of this utility model.
