Description

Technical Field

[0001] The utility model relates to the technical field of fruit and vegetable conveying equipment, and more specifically, to a swing type feeding device. Background Art

[0002] Fruits and vegetables are essential substances in people's daily diet, and the market demand for them is relatively large. In order to meet the market demand, automated equipment is now used to complete the entire process from fruit and vegetable picking - cleaning - sorting to packaging - selling. When fruits and vegetables are picked and enter the packaging and weighing conveyor line, they need to be fed from the front end of the conveyor line.

[0003] For small and medium-sized fruits, such as litchi, cherry tomatoes, and grey jujubes, after the fruits and vegetables are fed, the next process is to enter the weighing and packaging process, and multiple weighing hoppers are set in the weighing process. Since small and medium-sized fruits and vegetables are relatively light in weight, before the fruit and vegetable materials enter the weighing hopper, the conveyor transports the materials and distributes them to each weighing hopper. In existing feeding conveyors, there are often problems such as excessive accumulation of fruit and vegetable materials in some parts, resulting in uneven distribution. In particular, the fruits and vegetables transported in the over-accumulated parts will cause the weighing hopper at the corresponding position to be overweight, making the materials in the weighing hopper exceed the weighed target value. While in the parts where the incoming materials of the weighing hopper channel are too little, the weighing target value cannot be reached for a long time, thereby affecting the weighing speed of the whole machine.

[0004] For example, the patent with publication number CN116477120A discloses a swing feeding machine for small-particle fruits and vegetables. The feeding machine swings back and forth in a fan shape for feeding. In this way, the feeding amount at both ends of the swing point is often less than that in the middle, which is prone to the problem of uneven material distribution. Content of the Utility Model

For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to the specific situation.

[0040] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of this application are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so as to implement the embodiments of the present application described here.

[0041] A swing type feeding device provided in this embodiment is arranged at the starting end of the fruit and vegetable packaging weighing and conveying line. The fruit and vegetable materials are first fed into the conveying line through this feeding device, and then the subsequent processes of packaging and weighing are carried out.

[0042] Such as Figure 1As shown in the figure, a swinging feeding device includes a material swinging bin 1 and a driving assembly 3. Four first guiding members 15 are connected below the material swinging bin 1. The first guiding members 15 are used to guide the material swinging bin 1 in a swinging manner, and the guiding direction of the first guiding members 15 is different from the material conveying direction on the material swinging bin 1. In one case, the guiding direction of the first guiding members 15 is set perpendicular to the material conveying direction on the material swinging bin 1.

[0043] The driving assembly 3 includes a driving machine and a lower bracket 32. The material swinging bin 1 is located on the lower bracket 32. A second guiding member 33 is also connected to the lower bracket 32. The number of the second guiding members 33 corresponds to the number of the first guiding members 15. The first guiding members 15 and the second guiding members 33 are connected and cooperated with each other to jointly guide the swinging of the material swinging bin 1. The output end of the driving machine is connected to the material swinging bin 1, and the driving machine drives the material swinging bin 1 to make a reciprocating linear movement along the guiding direction of the first guiding members 15 and the second guiding members 33.

[0044] The swinging feeding device further includes a frame 4. The frame 4 is supported on the ground, and legs and wheels are arranged below it. The legs are used to stably support the frame 4, and the wheels can facilitate the movement of the frame 4, so as to facilitate setting the feeding device at the most suitable position. The material swinging bin 1 is arranged on the frame 4.

[0045] The material swinging bin 1 includes a bin inlet 11 and a bin outlet 12. A plurality of weighing hoppers 2 are arranged at the bin outlet 12. After the fruit and vegetable materials are discharged from the material swinging bin 1, they enter each weighing hopper 2 for subsequent packaging and weighing. The fruit and vegetable materials are fed onto the material swinging bin 1 through the bin inlet 11, and the driving machine drives the material swinging bin 1 to make a linear reciprocating swing. Specifically, see Figure 1 In the figure, the driving machine drives the material swinging bin 1 to move. Under the joint guidance of the first guiding members 15 and the second guiding members 33, the whole material swinging bin 1 makes a linear reciprocating swing in the left-right direction. During the swinging process, the materials are simultaneously conveyed along the material conveying direction. During the conveying process, the material swinging bin 1 swings as a whole, so as to fully spread the fruit and vegetable materials on the material swinging bin 1 evenly, avoid material piling and the phenomenon of too much material in a certain place, and thus avoid uneven feeding of fruits and vegetables at the bin outlet 12.

[0046] For this feeding device, the whole material swinging bin 1 swings left and right as a whole, fully avoiding the phenomenon of uneven material distribution, realizing stable material conveying during the whole conveying process, and making the materials on each part of the channel of the material swinging bin 1 flat and non-piling before the fruits and vegetables fall into the weighing hoppers 2. Therefore, during the conveying and subsequent weighing and metering, the fruits and vegetables are safe and stable without overshooting, thus avoiding damaging the fruits. At the same time, the weighing speed and accuracy of the whole machine are greatly improved, and the production efficiency is improved.

[0047] Combined with Figure 2As shown, the material placing bin 1 is inclined on the frame 4 so that the bin inlet 11 is lower than the bin outlet 12. When specifically setting the inclination of the material placing bin 1, the angle between the plane of the material placing bin 1 and the horizontal plane does not exceed 30°. For example, this angle is set to 15°. The inclined setting of the material placing bin 1 facilitates the discharge of the fruit and vegetable materials under the action of their own gravity. Setting the inclination angle of the material placing bin 1 not to exceed 30° can prevent the materials from discharging too quickly, so that the materials can be fully and evenly spread on the material placing bin 1.

[0048] Combined with Figure 3 、 Figure 4 and Figure 5 As shown, an upper support 16 is installed below the material placing bin 1, and the first guide member 15 is installed on the upper support 16. The material placing bin 1 is fixedly installed on the upper side of the upper support 16, and the first guide member 15 is installed on the other side of the upper support 16. Specifically, combined with Figure 6 and Figure 7 As shown, four first guide members 15 are provided, and the four first guide members 15 are symmetrically arranged with respect to the center of the output end of the driving machine. The material placing bin 1 is supported on the upper support 16, and the material placing bin 1 moves with the upper support 16. The first guide member 15 and the second guide member 33 are connected in cooperation. At the same time, the support point of the upper support 16 itself falls on the first guide member 15. The central symmetry setting of the first guide member 15 makes the material placing bin 1 more stably supported, preventing it from running unstably during the swinging process and affecting the even spreading effect of the fruits and vegetables. In other cases, the number of the first guide members 15 can also be set to other values according to the actual situation.

[0049] As a preferred embodiment, the first guide member 15 is a guide rod. The second guide member 33 is a guide slider, and the guide slider is sleeved and connected to the guide rod. The second guide member 33 is fixedly installed on the lower support 32, the driving machine is fixedly arranged relative to the lower support 32, the output end of the driving machine is specifically connected to the upper support 16, and the driving machine drives the upper support 16 to move, and the material placing bin 1 moves reciprocally with the upper support 16. During the reciprocating movement of the upper support 16, the guide rod reciprocates in the guide slider. In other embodiments, the first guide member 15 can also be a guide slider, and the second guide member 33 is a guide rod. Similarly, the guide slider is sleeved and connected to the guide rod.

[0050] Specifically, see Figure 6 As shown, as an embodiment, the driving machine is fixed on the lower support 32, and the lower support 32 is also fixed on the frame 4. A fixing plate 34 is fixedly connected to the lower support 32, and the driving machine is fixedly installed on the fixing plate 34. As a specific way, the driving machine is a servo motor.

[0051] The driving assembly 3 further includes a first connecting rod 31 and a second connecting rod 35. One end of the first connecting rod 31 is connected to the material swinging bin 1, and the other end is connected to the second connecting rod 35. At the same time, the second connecting rod 35 is also connected to the output end of the driving machine. Specifically, one end of the first connecting rod 31 is directly connected to the upper support 16, and is connected to the material swinging bin 1 through the upper support 16. The driving machine drives the second connecting rod 35 to rotate, drives the first connecting rod 31 to drive the material swinging bin 1 to move, and makes the material swinging bin 1 perform reciprocating linear swinging.

[0052] As a further improvement, the second connecting rod 35 includes an upper connecting rod 351 and a lower connecting rod 352 which are connected. The upper connecting rod 351 and the lower connecting rod 352 are arranged side by side up and down (described in terms of the Figure 6 viewing orientation). The first connecting rod 31 is connected to the upper connecting rod 351, and the output end of the driving machine is connected to the lower connecting rod 352. Moreover, the connection point between the first connecting rod 31 and the upper connecting rod 351 is eccentrically arranged relative to the connection point between the output end of the driving machine and the lower connecting rod 352, so that when the driving machine drives the second connecting rod 35 to rotate, the first connecting rod 31 can drive the material swinging bin 1 to reciprocate. In addition, by adjusting the eccentric distance between the connection point between the first connecting rod 31 and the upper connecting rod 351 and the connection point between the output end of the driving machine and the lower connecting rod 352, the swinging amplitude of the reciprocating swing of the material swinging bin 1 can be adjusted.

[0053] As a specific implementation manner, the first connecting rod 31 includes spherical plain bearings at both ends and an intermediate rod in the middle. The spherical plain bearings are respectively connected to the material swinging bin 1 and the second connecting rod 35. The spherical plain bearings and the intermediate rod are connected by threads, which is convenient for adjusting the length of the first connecting rod 31. The spherical plain bearings are adopted in the first connecting rod 31, so that the first connecting rod 31 can adaptively perform centering adjustment during the process of driving the material swinging bin 1 to reciprocate to adapt to the position of the material swinging bin 1.

[0054] Combined with Figure 1 and Figure 2 as shown, elastic guard plates 14 are respectively connected to both sides of the material swinging bin 1 along its feeding direction. The other side of the elastic guard plate 14 is connected to the machine frame 4. The elastic guard plate 14 can be made of elastic soft rubber or soft cloth, which does not prevent the swinging of the material swinging bin 1. One side of the elastic guard plate 14 is connected to the material swinging bin 1, and the other side is connected to the machine frame 4, which can seal the gap between the material swinging bin 1 and the machine frame 4 and prevent materials from falling into the inside of the machine frame 4, which is not convenient for cleaning. A baffle 13 is also arranged on the material swinging bin 1. The baffle 13 is located on the side where the material bin entrance 11 is located and the side where the elastic guard plate 14 is located. The baffle 13 is used to block the materials on the material swinging bin 1 to prevent the materials from falling off.

For example, it may be a fixed connection, a detachable connection, or an integral structure; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, or there may be internal communication between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0056] The above has schematically described the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto.
