Description

Technical Field

[0001] The utility model relates to the technical field of agricultural product sorting, in particular to a kicking mechanism for a fruit and vegetable carrier. Background Art

[0002] Fruit and vegetable sorting generally refers to the process of removing fruits and vegetables that do not meet standards or quality requirements during processing, packaging, or sales. This process is crucial for ensuring product quality, improving market competitiveness, and meeting consumer expectations for food safety and freshness. Existing fruit and vegetable sorting lines typically utilize automated equipment such as rollers, vibrating screens, air purge systems, and optical recognition systems to improve sorting efficiency and accuracy. Precise sorting and rejection minimizes waste caused by rejecting defective products.

[0003] Patent publication number CN216460264U discloses a multi-stage fruit and vegetable sorting device, comprising at least one movable sorting assembly, the sorting assembly comprising a support frame, at least one material support member rotatably connected to the upper end of the support frame, a pulling member rotatably connected to another fulcrum of the material support member, and a rotating member rotatably connected to the lower end of the pulling member. The other end of the rotating member is rotatably connected to the lower end of the support frame. The pulling member is subjected to force to control the rotating member to rotate outward around the support frame. The material support member is flipped outward around the support frame by the force of the pulling member, and the material automatically rolls from the material support member to the corresponding collection conveyor belt to achieve multi-stage sorting of fruits and vegetables. In a sorting device with such a structure, the material support member is in the form of a separate rotating shaft, with independent rotating shafts on both sides. This results in a large gap between the two material support members, which occasionally causes material to be stuck. In addition, the structure is complex and inconvenient to install.

[0004] Patent publication number CN220295281U discloses a universal reject mechanism. A reject element, activated by a reject cylinder, brakes a limit block. When the limit block leaves its contact surface with the material loading element, the material on the loading element naturally slides off. The number of limit blocks the reject element can contact allows a corresponding number of loading elements to reject the material, making it suitable for rejecting different types of materials. This reject mechanism has many parts and is complex. The reject element can occasionally become clumsy, leading to accidental ejection. The limit blocks of the bracket assembly wear out over time, failing to provide a limiting effect and causing the bracket to lose its ability to support the material. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a kicking mechanism for a fruit and vegetable carrier.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A kicking mechanism for a fruit and vegetable carrier, including a support beam with a certain length, on which a transmission chain moving along its length direction is provided. The transmission chain is connected with a number of carrier components straddling it. A pushing component capable of pushing the carrier components to actuate and achieve material dropping is also installed on the support beam. The carrier component includes a carrier base, at least one material supporting plate, a triggering support rod, and a connecting rod. The carrier base has a gate-shaped structure. The material supporting plate is rotatably connected to the upper end of the carrier base. The triggering support rod is an integral structural member, its upper end is rotatably connected to the material supporting plate through an upper hinge shaft, and the lower end of the triggering support rod is rotatably connected to one end of the connecting rod through a lower hinge shaft. The other end of the connecting rod is rotatably connected to the lower end of the carrier base through a lower fixed shaft. The material supporting plate, the upper hinge shaft, the triggering support rod, the lower hinge shaft, the connecting rod, and the lower fixed shaft form a connecting rod structure. When a downward force is applied to the material supporting plate, the lower hinge shaft is located at the dead point position of the connecting rod mechanism.

[0007] Further, the pushing component includes a pushing support, cylinders with the same number as the material supporting plates, and a pushing plate. The pushing support is connected to the bottom of the support beam. The cylinders are arranged perpendicular to the support beam, and the pushing end of the cylinder is connected to the pushing plate. When the cylinder pushes the pushing plate to contact the triggering support rod, the connecting rod mechanism disengages from the dead point position.

[0008] Furthermore, a first material supporting plate and a second material supporting plate are symmetrically arranged on the carrier base. The first material supporting plate is rotatably connected to the upper end of the first triggering support rod through a first upper hinge shaft. The lower end of the first triggering support rod is rotatably connected to one end of the first connecting rod through a first lower hinge shaft. The other end of the first connecting rod is rotatably connected to the lower end of the carrier base through a first lower fixed shaft. The second material supporting plate is rotatably connected to the upper end of the second triggering support rod through a second upper hinge shaft. The lower end of the second triggering support rod is rotatably connected to one end of the second connecting rod through a second lower hinge shaft. The other end of the second connecting rod is rotatably connected to the lower end of the carrier base through a second lower fixed shaft.

[0009] Furthermore, the cylinders include a first cylinder and a second cylinder. The pushing ends of the first cylinder and the second cylinder are in opposite directions and are respectively connected to a first pushing plate and a second pushing plate.

[0010] Furthermore, shaft holes are respectively opened at the inner ends of the first material supporting plate and the second material supporting plate, and a central fixed shaft connected to the carrier base penetrates through the shaft holes of both.

[0011] Furthermore, wear-resistant sleeves are respectively arranged in the shaft holes for installing the central fixed shaft, the first upper hinge shaft, the second upper hinge shaft, the first lower hinge shaft, the second lower hinge shaft, the first lower fixed shaft, and the second lower fixed shaft.

[0012] Further, the vehicle base is clamped on the drive chain. A notch is provided in the middle of the side wall of the vehicle base, and slot openings are provided upward along both sides of the notch to form a clamping flap with a certain elasticity. A round hole is provided in the clamping flap.

[0013] Furthermore, a wear-resistant strip is provided on the top of the support beam. The cross-section of the wear-resistant strip is in a "convex" shape. The roller of the drive chain contacts the top surface of the wear-resistant strip, the side plate of the drive chain contacts the two-step sides of the wear-resistant strip, and the chain shaft of the drive chain passes through the round hole of the clamping flap.

[0014] The beneficial effects of the present utility model are as follows:

[0015] In the vehicle component of the present utility model, the material supporting plate, the upper hinge shaft, the trigger rod, the connecting rod, the lower hinge shaft and the lower fixed shaft form a connecting rod structure. Under the action of gravity, the fruit and vegetable materials give a vertically downward force to the material supporting plate on the upper side. The lower hinge shaft is located inside the dead point position of the connecting rod and contacts the inner wall of the vehicle base and cannot move inward anymore. The connecting rod structure forms a stable state, playing a role in supporting the fruit and vegetable materials and conveying them forward with the vehicle component; the pushing plate contacts the lower side of the trigger support rod of the vehicle component and continues to move forward. The lower hinge shaft located inside the dead point of the connecting rod moves outward and crosses the dead point position of the connecting rod and continues to move outward. At this time, the connecting rod mechanism cannot support the fruit and vegetable materials on the upper side of the material supporting plate. Under the action of gravity, the fruit and vegetable materials will fall freely, thereby achieving the kicking action of the fruit and vegetable materials.

[0016] In the vehicle component of the present utility model, the two material supporting plates on both sides are coaxially arranged, and the gap between them is small, avoiding clamping of materials; the trigger support rod is an integral structural member, which is formed in one step without multiple-piece splicing, and the structure is simple; wear-resistant sleeves are provided in each shaft hole, greatly increasing the service life; the vehicle base is provided with a clamping flap structure, which is convenient for the installation and disassembly of the drive chain; the pushing component only includes a pushing support, a cylinder and a pushing plate, with a simple structure and stable use.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0033] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] As Figure 1 and Figure 2 As shown, a kicking mechanism for a fruit and vegetable carrier includes a support beam 1, wear-resistant strips 5, a drive chain 2, a plurality of carrier assemblies 3, and a pusher assembly 4. The support beam 1 serves as the overall support for the entire mechanism. The wear-resistant strips 5 are fixed to the top of the support beam 1. The drive chain 2 is mounted on the wear-resistant strips 5. The rollers of the drive chain 2 contact the top surface of the wear-resistant strips 5, and the side plates of the drive chain 2 contact the steps on both sides of the wear-resistant strips 5. Thus, the wear-resistant strips 5 limit the degree of freedom of the left and right movement of the drive chain 2, and under the action of gravity, the drive chain 2 can only move along the length direction of the wear-resistant strips 5.

[0035] As Figure 3 and Figure 4As shown in the figure, the vehicle component 3 includes a vehicle base 31, a symmetrically arranged first material supporting plate 32 and a second material supporting plate 33, a central fixed shaft 314, a first trigger rod 35, a second trigger rod 310, a first upper hinge shaft 34, a second upper hinge shaft 39, a first connecting rod 37, a second connecting rod 312, a first lower hinge shaft 36, a second lower hinge shaft 311, a first lower fixed shaft 38 and a second lower fixed shaft 313. The vehicle base 3 is in a portal structure. Axial holes are provided at the inner ends of the first material supporting plate 32 and the second material supporting plate 33, and a central fixed shaft 314 connected to the vehicle base 31 penetrates through the axial holes of both. The first material supporting plate 32 is rotatably connected to the upper end of the first trigger rod 35 through the first upper hinge shaft 34. The lower end of the first trigger rod 35 is rotatably connected to one end of the first connecting rod 37 through the first lower hinge shaft 36. The other end of the first connecting rod 37 is rotatably connected to the lower end of the vehicle base 31 through the first lower fixed shaft 38. The second material supporting plate 33 is rotatably connected to the upper end of the second trigger rod 310 through the second upper hinge shaft 39. The lower end of the second trigger rod 310 is rotatably connected to one end of the second connecting rod 312 through the second lower hinge shaft 311. The other end of the second connecting rod 312 is rotatably connected to the lower end of the vehicle base 31 through the second lower fixed shaft 313. Wear-resistant sleeves 315 are provided in the axial holes for installing the central fixed shaft 314, the first upper hinge shaft 34, the second upper hinge shaft 39, the first lower hinge shaft 36, the second lower hinge shaft 311, the first lower fixed shaft 38 and the second lower fixed shaft 313, and the rotation is flexible.

[0036] As Figure 5 and Figure 6 shown in the figure, the vehicle base 31 is clamped on the drive chain 2. A notch 316 is provided in the middle of the side wall of the vehicle base 31. Notch openings are provided upward along both sides of the notch 311 to form a clamping flap 317 with a certain elasticity. A round hole 318 is provided in the clamping flap 317. The chain shaft of the drive chain 2 penetrates through the round hole 318 of the clamping flap 317.

[0037] As Figure 7 shown in the figure, the pusher component 4 includes a pusher bracket 41, a first cylinder 42, a second cylinder 43, a first pusher plate 44 and a second pusher plate 45. The pusher bracket 41 is connected to the bottom of the support beam 1. The first cylinder 42 and the second cylinder 43 are both arranged perpendicular to the support beam 1. The pushing ends of the first cylinder 42 and the second cylinder 43 are in opposite directions and are respectively connected to the first pusher plate 44 and the second pusher plate 45.

[0038] Figure 8 ​As shown, when the equipment is running, the transmission chain 2 moves along the length direction of the support beam 1 and the wear-resistant strip 5, driving several carrier assemblies 3 installed on the transmission chain 2 to transport forward. When the carrier assembly 3 normally supports and transports materials, taking the connecting rod mechanism on one side as an example, the first supporting plate 32, the first upper hinge shaft 34, the first trigger rod 35, the first connecting rod 37, the first lower hinge shaft 36, and the first lower fixed shaft 38 form a connecting rod structure and each shaft hole is inlaid with a wear-resistant sleeve, which rotates flexibly. Under the action of gravity, the fruit and vegetable materials on the upper side of the first supporting plate 32 exert a vertical downward force on the first supporting plate 32. At this time, the first lower hinge shaft 36 is located on the inside of the dead point position of the connecting rod mechanism and contacts the inner wall of the carrier base 31 and cannot move inward any further. The connecting rod structure forms a stable state, plays a role in supporting the fruit and vegetable materials, and transports them forward with the carrier assembly.

[0039] like Figure 9 As shown, taking the connecting rod mechanism on one side as an example, when the carrier assembly 3 with fruit and vegetable materials reaches the kicking position, the first cylinder 42 of the pushing assembly 4 starts to move, and at the same time drives the first pushing plate 44 to push forward. The first pushing plate 44 contacts the lower side of the first trigger support rod 35 of the carrier assembly 3 and continues to move forward. At this time, the first lower hinge shaft 36 located on the inner side of the dead point position of the connecting rod mechanism moves outward, passes the dead point position and continues to move outward. At this time, the connecting rod mechanism cannot support the fruit and vegetable materials located on the upper side of the first supporting plate 32. Under the action of gravity, the fruit and vegetable materials will fall freely, thereby achieving the kicking action of the fruit and vegetable materials.

[0040] 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.
