Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting, and in particular to a fruit and vegetable conveying device and a fruit and vegetable sorting machine. Background Technology

[0002] As people pursue a higher quality of life, more and more people are demanding higher quality fruits and vegetables, making fruit and vegetable sorting an important technology.

[0003] In automated fruit and vegetable sorting, it is necessary to separate the stems and fruits. First, the fruits and vegetables are placed on the conveyor belt of the fruit and vegetable conveying device. The conveyor belt carries the fruits and vegetables into the rejection area. The conveyor belt has through holes, and the fan is located on one side of the conveyor belt. The fan can blow air onto the conveyor belt, and the airflow blows through the through holes onto the fruits and vegetables to separate the stems, branches and leaves from the fruits.

[0004] However, after the fruit stems and branches are removed from the fruits and vegetables, some fruit stems, peels, or fruit powder will remain on the conveyor belt. If these residues are not removed in time, the fruits and vegetables transported by the conveyor belt will have residues of fruit stems, peels, or fruit powder adhering to their surfaces, affecting the final quality of the sorted fruits and vegetables. At the same time, the residues of fruit stems, peels, or fruit powder can easily clog the holes of the conveyor belt. If not removed in time, the airflow will not be able to pass through the holes, thus affecting the separation of fruit stems, branches, leaves, and fruits. Utility Model Content

[0005] The present invention aims to provide a fruit and vegetable conveying device and a fruit and vegetable sorting machine to solve the technical problem in the prior art that the failure to promptly handle residues on the conveyor belt affects the quality of fruit and vegetable sorting and the separation effect of fruit stems, branches and leaves and fruits.

[0006] To solve the above-mentioned technical problems, this utility model provides a fruit and vegetable conveying device, including: a frame, wherein the frame is provided with a first sliding groove and a second sliding groove;

[0007] A conveyor belt, which is mounted on the frame, is used to transport fruits and vegetables;

[0008] A cleaning assembly is mounted on the frame. The cleaning assembly includes a first roller brush and a second roller brush. The opposite ends of the first roller brush are respectively inserted into a corresponding first sliding groove, and the opposite ends of the second roller brush are respectively inserted into a corresponding second sliding groove. There is a cleaning gap between the first roller brush and the second roller brush, and the conveyor belt passes through the cleaning gap.

[0009] A first drive assembly is connected to the first roller brush and the second roller brush, and the first drive assembly is used to drive the first roller brush and the second roller brush to rotate.

[0010] A second drive assembly is connected to the first roller brush and the second roller brush. The second drive assembly is used to drive the first roller brush to move along the first sliding groove. The second drive assembly is also used to drive the second roller brush to move along the second sliding groove, so that the first roller brush and the second roller brush simultaneously move closer to the conveyor belt to abut against the conveyor belt or simultaneously move away from the conveyor belt to disengage from the conveyor belt.

[0011] With the above structure, the second drive assembly drives the first roller brush to move along the first sliding groove, and at the same time, the second drive assembly drives the second roller brush to move along the second sliding groove, so that the first roller brush and the second roller brush approach the conveyor belt at the same time; the first roller brush and the second roller brush abut against the opposite sides of the conveyor belt respectively, and the first roller brush and the second roller brush rotate relative to the conveyor belt to clean the opposite sides of the conveyor belt.

[0012] In some embodiments, the second drive assembly includes a second drive member and a linkage plate. The second drive member is mounted on the frame, and the output end of the second drive member is connected to the linkage plate. One end of the first roller brush and one end of the second roller brush are located at opposite ends of the linkage plate. The middle part of the linkage plate is rotatably connected to the frame, and both the first sliding groove and the second sliding groove are arc-shaped groove structures.

[0013] With the above structure, under the premise that the relative distance between the first roller brush and the second roller brush remains unchanged, the first roller brush and the second roller brush can simultaneously approach the conveyor belt to abut against the conveyor belt. The first roller brush and the second roller brush are not located on the same horizontal plane. The conveyor belt is slightly bent between the first roller brush and the second roller brush to achieve the effect of being pressed against the first roller brush and the second roller brush. Pressing against the conveyor belt can increase the friction between the first roller brush and the second roller brush and the conveyor belt to improve the cleaning effect.

[0014] In some embodiments, the fruit and vegetable conveying device further includes a transmission component, which includes a first gear and a second gear. The first gear is sleeved on one end of the first roller brush near the linkage plate, and the second gear is sleeved on one end of the second roller brush near the linkage plate. The first gear and the second gear are meshed and connected, and the output end of the first drive component is connected to one end of the second roller brush.

[0015] With the above structure, only one first drive component is needed to drive the first roller brush and the second roller brush to rotate simultaneously, and the first roller brush and the second roller brush rotate at the same speed.

[0016] In some embodiments, the fruit and vegetable conveying device further includes a suspension frame, the suspension frame including an extension and a mounting portion, the extension being connected to the linkage plate and extending along the direction from the frame to the linkage plate, the mounting portion being connected to the extension and extending downward, the first drive assembly being connected to the mounting portion, and the mounting portion having a receiving gap between its sidewall facing the linkage plate and the linkage plate, the first gear and the second gear being located within the receiving gap.

[0017] With the above structure, both the first gear and the second gear are located within the housing gap, making the structure more compact and preventing the first drive component from interfering with the operation of the first gear and the second gear.

[0018] In some embodiments, the first drive assembly includes a first drive member, a first helical gear, and a second helical gear. The output shaft of the first drive member is arranged in a direction perpendicular to the rotation axis of the second roller brush. The first helical gear is sleeved on the output shaft of the first drive member, and the second helical gear is sleeved on one end of the second roller brush. The first helical gear and the second helical gear are meshed and connected.

[0019] The above structure avoids making the overall length of the fruit and vegetable conveying device too long, thus making the overall structure of the fruit and vegetable conveying device more compact.

[0020] In some embodiments, the cleaning assembly further includes a first mounting base and a second mounting base. One end of the first roller brush passes through the linkage plate and is mounted on the first mounting base, and one end of the second roller brush passes through the linkage plate and is mounted on the second mounting base. The linkage plate includes a first connecting portion, a plate body portion, a second connecting portion, and a supporting portion. The first connecting portion and the second connecting portion are respectively connected to opposite sides of the plate body portion. The first connecting portion is rotatably connected to the output end of the second drive member. The opposite ends of the second connecting portion are respectively connected to one end of the first roller brush and one end of the second roller brush. The plate body portion is rotatably connected to the frame. The supporting portion is connected to the second connecting portion. The supporting portion extends along the direction from the frame to the linkage plate. The first mounting base and the second mounting base are respectively mounted on opposite ends of the supporting portion.

[0021] With the above structure, when the plate part rotates, the supporting part rotates accordingly, and the corresponding first roller brush and second roller brush rotate simultaneously and in the same direction of rotation, so that the first roller brush and second roller brush move closer to or further away from the conveyor belt at the same time.

[0022] In some embodiments, the second connecting part is rotatably connected to the frame via a connecting shaft, and the first connecting part is connected to the output end of the second driving member via a hinge shaft. The connecting shaft and the hinge shaft are parallel to each other and horizontally arranged, and are located in different vertical planes. The output end of the second driving member can move along a straight line that is inclined relative to the horizontal plane.

[0023] With the above structure, the connecting shaft and the hinge shaft are parallel to each other and horizontally arranged, and located in different vertical planes. The output end of the second drive member can move along a straight line that is inclined relative to the horizontal plane, so that there is a long lever arm between the straight line and the connecting shaft, which allows the second drive member to drive the first connecting part to rotate around the connecting shaft with less force.

[0024] In some embodiments, the number of the second drive components is two, and the two second drive components are respectively mounted on the outer side walls of opposite sides of the frame;

[0025] The frame has a first adjustment groove and a second adjustment groove on its opposite side walls. One end of the second driving member facing away from the linkage plate is slidably installed in the first adjustment groove, and the other end of the second driving member facing away from the linkage plate is received in the second adjustment groove. Both the first adjustment groove and the second adjustment groove are arc-shaped groove structures.

[0026] With the above structure, one second driving member can move along the first adjusting groove to change its position, and another second driving member can also move along the second adjusting groove to change its position, so that the trajectory of the second roller brush driven by the second driving member is more in line with the first sliding groove and the second sliding groove, avoiding excessive interference between the movement trajectory of the second roller brush and the second sliding groove, which would cause the second roller brush to collide with the groove wall of the second sliding groove and cause damage.

[0027] In some embodiments, the fruit and vegetable conveying device further includes a reversing assembly and a fan. The reversing assembly includes a reversing roller. The conveyor belt is wound around a plurality of the reversing rollers. The conveyor belt includes a rejection section, a cleaning section, and a circulation section. A reversing roller is disposed between any two adjacent rejection sections, cleaning sections, and circulation sections. The rejection sections, cleaning sections, and circulation sections enclose a receiving cavity, and the fan is received within the receiving cavity.

[0028] With the above structure, the fan is housed in the receiving cavity, making the overall fruit and vegetable conveying device more compact.

[0029] This utility model also provides a fruit and vegetable sorting machine, including the fruit and vegetable conveying device described in any of the above embodiments.

[0030] Compared with the prior art, in this embodiment of the utility model, the first roller brush and the second roller brush are driven by the first driving component to move. The first roller brush and the second roller brush abut against the opposite sides of the conveyor belt, so that the opposite sides of the conveyor belt can be cleaned at the same time, thereby improving the cleaning efficiency of the fruit and vegetable conveying device.

[0042] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of a fruit and vegetable conveying device provided in one embodiment of the present invention from a first angle; Figure 2 yes Figure 1 A schematic diagram of the second angle of the fruit and vegetable conveying device.

[0043] An embodiment of this utility model provides a fruit and vegetable conveying device 100, including a frame 10, a conveyor belt 20, a cleaning component 30, a first drive component 40, and a second drive component 50. The frame 10 has a first sliding groove 11 and a second sliding groove 12. The conveyor belt 20 is installed on the frame 10 and is used to convey fruits and vegetables. The cleaning component 30 is installed on the frame 10 and includes a first roller brush 31 and a second roller brush 32. The opposite ends of the first roller brush 31 are respectively inserted into a corresponding first sliding groove 11, and the opposite ends of the second roller brush 32 are respectively inserted into a corresponding second sliding groove 12. The first roller brush 31 and the second roller brush 32 are respectively inserted into a corresponding second sliding groove 12. A cleaning gap 33 is provided between the two roller brushes 32, and the conveyor belt 20 passes through the cleaning gap 33; a first drive assembly 40 is connected to the first roller brush 31 and the second roller brush 32, and the first drive assembly 40 is used to drive the first roller brush 31 and the second roller brush 32 to rotate; a second drive assembly 50 is connected to the first roller brush 31 and the second roller brush 32, and the second drive assembly 50 is used to drive the first roller brush 31 and the second sliding groove 12 to move along the first sliding groove 11 and the second sliding groove 12 respectively, so that the first roller brush 31 and the second roller brush 32 simultaneously approach the conveyor belt 20 to abut against the conveyor belt 20 or simultaneously move away from the conveyor belt 20 to disengage from the conveyor belt 20.

[0044] Specifically, the second drive assembly 50 drives the first roller brush 31 to move along the first sliding groove 11, and simultaneously drives the second roller brush 32 to move along the second sliding groove 12, so that the first roller brush 31 and the second roller brush 32 simultaneously approach the conveyor belt 20 to abut against the opposite sides of the conveyor belt 20. At this time, the first drive assembly 40 drives the first roller brush 31 and the second roller brush 32 to rotate, thereby cleaning the opposite sides of the conveyor belt 20. The opposite sides of the conveyor belt 20 can be cleaned simultaneously, improving the cleaning efficiency of the fruit and vegetable conveying device 100. The second drive assembly 50 drives the first roller brush 31 and the second sliding groove 12 to move along the first sliding groove 11 and the second sliding groove 12 respectively, so that the first roller brush 31 and the second roller brush 32 simultaneously move away from the conveyor belt 20 to disengage from the conveyor belt 20, which facilitates the cleaning of the first roller brush 31 and the second roller brush 32. In addition, by driving the first roller brush 31 and the second sliding groove 12 along the first sliding groove 11 and the second sliding groove 12 respectively by the second drive component 50, the distance between the first roller brush 31 and the second roller brush 32 and the conveyor belt 20 can be adjusted to accommodate conveyor belts 20 of different thicknesses, and the tightness of the first roller brush 31 and the second roller brush 32 against the conveyor belt 20 can also be adjusted.

[0045] The first drive assembly 40 may include a motor, and the conveyor belt 20 may be a chain plate, a transmission belt, etc. The conveyor belt 20 may be wound around a drive roller, which is mounted on the frame 10. One of the drive rollers is connected to the first drive assembly 40. The first drive assembly 40 can drive the drive roller to rotate, thereby moving the conveyor belt 20 to transport fruits and vegetables. The conveyor belt 20 has through holes and surrounds a fan. Fruits and vegetables are placed on the conveyor belt 20, and the conveyor belt 20 carries the fruits and vegetables over the fan. The fan blows air upwards, and the airflow passes through the through holes onto the fruits and vegetables on the conveyor belt 20 to separate the fruit stems, branches, leaves, and fruits.

[0046] The first roller brush 31 and the second roller brush 32 may include brushes or soft materials, which are disposed on the circumferential outer surfaces of the first roller brush 31 and the second roller brush 32.

[0047] In one embodiment, the second drive assembly 50 includes a second drive member 51 and a linkage plate 52. The second drive member 51 is mounted on the frame 10, and the output end of the second drive member 51 is connected to the linkage plate 52. One end of the first roller brush 31 and one end of the second roller brush 32 are respectively located at opposite ends of the linkage plate 52. The middle part of the linkage plate 52 is rotatably connected to the frame 10. The first sliding groove 11 and the second sliding groove 12 are both arc-shaped groove structures.

[0048] Specifically, the second driving member 51 is connected to one end of the linkage plate 52. The second driving member 51 drives the linkage plate 52 to rotate relative to the frame 10. The linkage plate 52 drives the first roller brush 31 and the second roller brush 32 to move simultaneously. In detail, the second driving member 51 drives the linkage plate 52 to rotate. When the linkage plate 52 rotates, one end of the first roller brush 31 moves upward along the first sliding groove 11, and the second roller brush 32 moves downward along the second sliding groove 12. The first roller brush 31 and the second roller brush 32 approach the conveyor belt 20 at the same time. With this configuration, under the premise that the relative distance between the first roller brush 31 and the second roller brush 32 remains unchanged, the first roller brush 31 and the second roller brush 32 can simultaneously approach the conveyor belt 20 to abut against the conveyor belt 20. Moreover, the first roller brush 31 and the second roller brush 32 are not located on the same horizontal plane. The conveyor belt 20 is slightly bent between the first roller brush 31 and the second roller brush 32 to achieve the effect of being pressed against by the first roller brush 31 and the second roller brush 32. Pressing against the conveyor belt 20 can increase the friction between the first roller brush 31 and the second roller brush 32 and the conveyor belt 20, thereby improving the cleaning effect.

[0049] Furthermore, in this embodiment, both the first sliding groove 11 and the second sliding groove 12 are arc-shaped through grooves, and the first sliding groove 11 and the second sliding groove 12 are arranged opposite to each other. The two first sliding grooves 11 are respectively formed on opposite side walls of the frame 10, and the opposite ends of the first roller brush 31 are respectively received in the two first sliding grooves 11 and respectively rotatably connected to one end of the two linkage plates 52. The two second sliding grooves 12 are respectively formed on opposite side walls of the frame 10, and the opposite ends of the second roller brush 32 are respectively received in the two second sliding grooves 12 and respectively rotatably connected to the other end of the two linkage plates 52.

[0050] The middle part of the linkage plate 52 can be rotatably connected to the frame 10 via the connecting shaft 54 ​​(see...). Figure 6 The linkage plate 52 can be a sheet metal part.

[0051] The second driving component 51 can be a cylinder or a linear motor, and one end of the linkage plate 52 is rotatably connected to the piston rod of the cylinder or the output end of the linear motor.

[0052] In one embodiment, the fruit and vegetable conveying device 100 further includes a transmission assembly 60, which includes a first gear 61 and a second gear 62. The first gear 61 is sleeved on one end of the first roller brush 31 that passes through the linkage plate 52, and the second gear 62 is sleeved on one end of the second roller brush 32 that passes through the linkage plate 52. The first gear 61 and the second gear 62 are meshed together, and the output end of the first drive assembly 40 is connected to one end of the second roller brush 32.

[0053] Specifically, the first drive assembly 40 drives the second roller brush 32 to rotate. The rotation of the second roller brush 32 drives the second gear 62 to rotate. The first gear 61 and the second gear 62 are meshed together. The rotation of the second gear 62 drives the first gear 61 to rotate, and the rotation of the first gear 61 simultaneously drives the first roller brush 31 to rotate. This arrangement allows only one first drive assembly 40 to drive the first roller brush 31 and the second roller brush 32 to rotate simultaneously, and the rotation speeds of the first roller brush 31 and the second roller brush 32 are the same.

[0054] In one embodiment, there are two second drive components 50, which are respectively installed on the opposite side walls of the frame 10. The frame 10 has a first adjustment groove 13 and a second adjustment groove 14 on opposite sides. One second drive component 51 is slidably installed in the first adjustment groove 13 at one end away from the linkage plate 52, and the other second drive component 51 is slidably installed in the second adjustment groove 14 at one end away from the linkage plate 52. Both the first adjustment groove 13 and the second adjustment groove 14 are arc-shaped groove structures.

[0055] Specifically, the two second drive members 51 work simultaneously to make the opposite sides of the first roller brush 31 and the second roller brush 32 move at the same time, ensuring the stability of the first roller brush 31 and the second roller brush 32 during movement, so as to avoid the first roller brush 31 or the second roller brush 32 tilting to one side.

[0056] One second driving member 51 can move along the first adjusting groove 13 to change its position, and another second driving member 51 can move along the second adjusting groove 14 to change its position, so that the trajectory of the second roller brush 32 driven by the second driving member 51 is more in line with the first sliding groove 11 and the second sliding groove 12, so as to avoid excessive interference between the movement trajectory of the second roller brush 32 and the first sliding groove 11 and the second sliding groove 12, which would cause the second roller brush 32 to collide with the groove wall of the first sliding groove 11 and the groove wall of the second sliding groove 12 and cause damage.

[0057] See Figure 3 , Figure 3 yes Figure 1 A simplified schematic diagram of the first and second roller brushes in operation in a fruit and vegetable conveying device.

[0058] The rotation direction of the first roller brush 31 relative to the conveyor belt 20 is opposite to that of the second roller brush 32 relative to the conveyor belt 20. This arrangement ensures that the direction of the friction force on both sides of the conveyor belt 20 is consistent, so as to ensure that the direction of the residue falling off the surface on both sides of the conveyor belt 20 is consistent, so as to facilitate the collection of the residue.

[0059] See Figure 4 and Figure 5 , Figure 4 yes Figure 1 A schematic diagram of the fruit and vegetable conveying device from the third angle; Figure 5 yes Figure 4 Enlarged structural diagram of part A.

[0060] In one embodiment, the fruit and vegetable conveying device 100 further includes a suspension frame 70, which includes an extension 71 and a mounting portion 72. The extension 71 is connected to the linkage plate 52 and extends along the direction from the frame 10 to the linkage plate 52. The mounting portion 72 is connected to the extension 71 and extends downward. The first drive assembly 40 is connected to the mounting portion 72. The side wall of the mounting portion 72 facing the linkage plate 52 has a receiving gap 53 between it and the linkage plate 52. The first gear 61 and the second gear 62 are both located within the receiving gap 53.

[0061] Specifically, the extension 71 is connected between the linkage plate 52 and the mounting part 72, the first drive assembly 40 is mounted on the mounting part 72, and the first gear 61 and the second gear 62 are both located within the receiving gap 53, so that the structure is more streamlined and the first drive assembly 40 can be prevented from interfering with the operation of the first gear 61 and the second gear 62.

[0062] The suspension bracket 70 may be a sheet metal part, and the first drive assembly 40 may be mounted to the mounting part 72 by screws.

[0063] In one embodiment, the first drive assembly 40 includes a first drive member, a first helical gear, and a second helical gear. The output shaft of the first drive member is arranged in a direction perpendicular to the rotation axis of the second roller brush 32. The first helical gear is sleeved on the output shaft of the first drive member, and the second helical gear is sleeved on one end of the second roller brush 32. The first helical gear and the second helical gear are meshed and connected.

[0064] In this embodiment, the first driving component is a servo motor. The rotation of the first driving component drives the first helical gear to rotate, which in turn drives the second helical gear to rotate, thereby driving the second roller brush 32 to rotate. The first roller brush 31 and the second roller brush 32 are placed horizontally, and the length direction of the first driving component is inclined downward to avoid the fruit and vegetable conveying device 100 being too long along its horizontally placed length, so as to make the overall structure of the fruit and vegetable conveying device 100 more compact.

[0065] See Figure 2 , Figure 4 and Figure 6 , Figure 6 yes Figure 1 A schematic diagram of the linkage plate of the fruit and vegetable conveying device.

[0066] In one embodiment, the cleaning assembly 30 further includes a first mounting base 34 and a second mounting base 35. One end of the first roller brush 31 passes through the linkage plate 52 and is mounted on the first mounting base 34, and one end of the second roller brush 32 passes through the linkage plate 52 and is mounted on the second mounting base 35. The linkage plate 52 includes a first connecting portion 521, a plate body portion 522, a second connecting portion 523, and a supporting portion 524. The first connecting portion 521 and the second connecting portion 523 are respectively connected to opposite sides of the plate body portion 522. The first connecting portion 521 is rotatably connected to the output end of the second driving member 51. The opposite ends of the second connecting portion 523 are respectively connected to one end of the first roller brush 31 and one end of the second roller brush 32. The plate body portion 522 is rotatably connected to the frame 10. The supporting portion 524 is connected to the second connecting portion 523. The supporting portion 524 extends along the direction from the frame 10 to the linkage plate 52. The first mounting base 34 and the second mounting base 35 are respectively mounted on opposite ends of the supporting portion 524.

[0067] Specifically, the first connecting part 521, the plate part 522, the second connecting part 523 and the supporting part 524 are an integrated structure. The plate part 522 is roughly rectangular. The first connecting part 521 and the second connecting part 523 are located on the upper and lower sides of the plate part 522, respectively. The first connecting part 521 extends along one side of the plate part 522. The first driving member is connected to the first connecting part 521. In this embodiment, the second driving member 51 is a cylinder. The plate part 522 is rotatably connected to the frame 10. The second driving member 51 drives the first connecting part 521 to move up and down, and the plate part 522 rotates accordingly. The second connecting part 523 is connected between the plate part 522 and the support part 524. The support part 524 extends away from the frame 10. The first mounting seat 34 and the second mounting seat 35 are located on opposite sides of the support part 524. The first roller brush 31 and the second roller brush 32 both pass through the second connecting part 523. One end of the first roller brush 31 passes through the second connecting part 523 and is connected to the first mounting seat 34. One end of the second roller brush 32 passes through the second connecting part 523 and is connected to the second mounting seat 35. When the plate body 522 rotates, the support part 524 rotates accordingly, and the corresponding first roller brush 31 and second roller brush 32 rotate simultaneously and in opposite directions, so that the first roller brush 31 and second roller brush 32 simultaneously move closer to or further away from the conveyor belt 20.

[0068] Both the first mounting base 34 and the second mounting base 35 can be bearing seats.
