Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a fruit and vegetable conveying mechanism and a fruit and vegetable sorting device. Background Technology
[0002] Currently, fruits and vegetables are a type of food that people often consume. Fruits and vegetables include cherries, apples, pears, and tomatoes, among others. After ripening, fruits and vegetables need to be harvested and then transported to factories for sorting and processing to facilitate subsequent packaging and sales.
[0003] In related technologies, fruit and vegetable sorting devices may include fruit and vegetable conveying mechanisms, which are used to move fruits and vegetables within the sorting device; in some cases, the fruit and vegetable conveying mechanism needs to pick up fruits and vegetables from one place and move them to another.
[0004] However, under normal circumstances, the fruit and vegetable conveying mechanism picks up one or a batch of fruits and vegetables at a time, then the conveyor moves the fruits and vegetables and puts them down. Then the conveying mechanism moves back to the initial position and picks up one or a batch of fruits and vegetables again. The low frequency of picking up fruits and vegetables by the conveying mechanism results in low conveying efficiency. Utility Model Content
[0005] The present invention aims to provide a fruit and vegetable conveying mechanism and a fruit and vegetable sorting device to solve the technical problem that the fruit and vegetable conveying mechanism has a low frequency of picking up fruits and vegetables, resulting in low conveying efficiency.
[0006] The technical problem solved by this utility model embodiment is addressed by the following technical solution:
[0007] A fruit and vegetable conveying mechanism is provided, comprising:
[0008] frame;
[0009] A rotating frame, rotatably connected to the machine frame, the rotating frame including multiple vertical guide rails;
[0010] A circular guide rail is installed on the frame; in the horizontal direction, the circular guide rail is arranged around the rotation axis of the rotating frame; the circular guide rail includes a first guide section and a second guide section, the height of the first guide section is greater than the height of the second guide section, the number of the first guide section and the number of the second guide section are both at least two, and the first guide section and the second guide section are arranged alternately;
[0011] A gripping assembly, wherein there are multiple gripping assemblies, the gripping assemblies are mounted on the rotating frame, the gripping assemblies are vertically movably connected to the rotating frame, the gripping assemblies are used to grip fruits and vegetables, the gripping assemblies include a first guide member and a second guide member, one of the first guide members is connected to a corresponding vertical guide rail, and the second guide member is connected to the annular guide rail.
[0012] With the above structure, during the rotation of the rotating frame relative to the machine frame, it can drive the second guide member to move along the circular guide track. When the second guide member moves to the second guide section, the height of the gripping component is lower, and the lower end of the gripping component is lower, so the gripping component can contact the surface of the fruits and vegetables and pick them up. When the second guide member moves to the first guide section, the lower end of the gripping component is raised, so the gripping component can lift the fruits and vegetables.
[0013] When the second guide component moves from the first guide section to the second guide section, the lower end of the gripping component holding the fruits and vegetables decreases again, allowing the gripping component to lower the gripped fruits and vegetables, thus completing the fruit and vegetable conveying process. There are multiple gripping components, each capable of independently conveying fruits and vegetables, ensuring that the fruit and vegetable conveying mechanism can convey fruits and vegetables evenly and efficiently.
[0014] In addition, when the second guide member moves from the first guide section to the second guide section, or from the second guide section to the first guide section, the gripping component can move vertically relative to the frame. The vertical guide rail guides the first guide member to improve the stability of the gripping component during movement.
[0015] In some embodiments, the rotating frame includes an upper turntable and a lower turntable, the upper end of the gripping component passes through the upper turntable, the lower end of the gripping component passes through the lower turntable, the gripping component is vertically movably connected to the upper turntable and the lower turntable, the upper end of the vertical guide rail is connected to the upper turntable, and the lower end of the vertical guide rail is connected to the lower turntable.
[0016] With the above structure, the upper end of the vertical guide rail is connected to the upper turntable, and the lower end of the vertical guide rail is connected to the lower turntable, so that the vertical guide rail can be more stably connected to the rotating frame, making the guiding effect of the vertical guide rail on the first guide member better, and the gripping component can be more stable when moving vertically relative to the rotating frame.
[0017] In some embodiments, the gripping component further includes a body and a suction cup, the upper end of the body is inserted through the upper turntable, the lower end of the body is inserted through the lower turntable, the first guide and the second guide are both connected to the body, and the suction cup is connected to the lower end of the body;
[0018] The rotating frame further includes a first connector and a second connector. The first connector is sleeved on the main body and fixed to the upper turntable. The main body is vertically movably connected to the first connector. The second connector is sleeved on the main body and fixed to the lower turntable. The main body is vertically movably connected to the second connector.
[0019] With the above structure, the suction cup can generate negative pressure when it contacts the surface of fruits and vegetables, allowing the suction cup to adhere to the surface of the fruits and vegetables, and enabling the gripping component to pick up the fruits and vegetables. In addition, the first connecting member is used to connect the main body to the upper turntable, and the second connecting member is used to connect the main body to the lower turntable 26, so that the gripping component can move more stably vertically relative to the rotating frame.
[0020] In some embodiments, the gripping component further includes a limiting block and an elastic reset member. The limiting block is connected to the upper end of the main body, and the elastic reset member is sleeved on the main body. The upper end of the elastic reset member is connected to the limiting block, and the lower end of the elastic reset member is connected to the first connector.
[0021] With the above structure, the limiting block and the first connecting member clamp the elastic reset member. When the gripping component moves from the first guide section to the second guide section, the gripping component falls under the action of gravity. The elastic reset member can play a buffering role during the falling process of the gripping component to avoid excessive impact force when the suction cup component contacts the surface of fruits and vegetables, which would cause damage to the fruits and vegetables.
[0022] In some embodiments, both the first guide and the second guide include rollers; in the same gripping assembly, the first guide and the second guide are located at the same height; each vertical guide rail has a vertical guide groove, and the two oppositely arranged side walls of each vertical guide groove clamp a corresponding first guide, and each first guide is rotatably connected to a corresponding vertical guide groove.
[0023] With the above structure, both the first and second guide members include rollers to reduce the friction between the second guide member and the annular guide rail, thereby reducing wear on both. Additionally, each vertical guide groove has two opposing sidewalls clamping a corresponding first guide member, allowing the vertical guide rail to provide better guidance for the first guide member.
[0024] In some embodiments, the gripping assembly further includes a third connector detachably connected to the body and located between the upper turntable and the lower turntable; in the same gripping assembly, the first guide and the second guide are connected to the third connector.
[0025] With the above structure, the third connector can be connected to the first guide and the second guide, and the third connector can be detached from the main body; thus, the position of the third connector relative to the main body can be changed to adjust the height of the first guide and the second guide relative to the main body, and the first guide and the second guide can be replaced.
[0026] In some embodiments, the gripping component is located between the annular guide rail and a corresponding vertical guide rail; in the same gripping component, the first guide is located on one side of the third connector, and the second guide is located on the other opposite side of the third connector.
[0027] With the above structure, the gripping components are located between the circular guide rail and a corresponding vertical guide rail, so that all gripping components can be evenly distributed on the outer ring of the rotating frame, and all vertical guide rails can be evenly distributed on the inner ring of the rotating frame. The interval between two adjacent gripping components can be smaller, and the fruit and vegetable conveying mechanism can include more gripping components, further improving the conveying efficiency of the fruit and vegetable conveying mechanism.
[0028] In some embodiments, the annular guide track further includes an inclined section disposed between the first guide section and an adjacent second guide section.
[0029] With the above structure, the inclined section is set between the first guide section and the adjacent second guide section so that the second guide member can be buffered when moving between the first guide section and the second guide section, reducing the speed of the gripping component when it falls and preventing the gripping component from crushing the fruits and vegetables when it falls.
[0030] In some embodiments, the annular guide rail is located on the outside of the rotating frame.
[0031] With the above structure, the annular guide rail is located on the outside of the rotating frame, so that the annular guide rail can be installed on the frame.
[0032] Compared with the prior art, during the rotation of the rotating frame relative to the machine frame, it can drive the second guide member to move along the circular guide track. When the second guide member moves to the second guide section, the height of the gripping component is lower, and the lower end of the gripping component is lower, so the gripping component can contact the surface of the fruits and vegetables and pick them up. When the second guide member moves to the first guide section, the lower end of the gripping component is raised, and the gripping component can lift the fruits and vegetables.
[0033] When the second guide component moves from the first guide section to the second guide section, the lower end of the gripping component holding the fruits and vegetables decreases again, allowing the gripping component to lower the gripped fruits and vegetables, thus completing the fruit and vegetable conveying process. There are multiple gripping components, each capable of independently conveying fruits and vegetables, ensuring that the fruit and vegetable conveying mechanism can convey fruits and vegetables evenly and efficiently.
[0034] In addition, when the second guide member moves from the first guide section to the second guide section, or from the second guide section to the first guide section, the gripping component can move vertically relative to the frame. The vertical guide rail guides the first guide member to improve the stability of the gripping component during movement. Attached Figure Description
