Description

Technical Field

[0001] The invention belongs to the technical field of agricultural picking equipment, and in particular relates to a separation device for fruit picking. Background Art

[0002] When picking agricultural products, in order to reduce labor costs, it is usually necessary to separate the fruits from the leaves before packaging the fruits, such as apples, bell peppers, etc. Existing picking machines often pick fruits with scattered broken branches and fallen leaves, which need to be cleaned separately. Existing fruit and leaf separation methods mostly use manual labor, or set the conveyor belt used for transportation to be hollow so that the leaves can fall automatically during transportation.

[0003] For example, the Chinese utility model patent with patent announcement number CN213792169U and announcement date 2021.07.27 discloses a green plum fruit and leaf separation device, the structure of which includes a base, a separation mechanism, a rotating column, a bearing seat, a motor, a small wheel, a collecting mechanism, gears, plates, a cylindrical seat, a fixing rod, a flat belt and a large wheel. The front and rear parts of the left and right sides of the base are provided with bearing seats, a groove is opened at the top of the bearing seat, a small wheel is rotatably connected in the groove at the top of the bearing seat, and a rotating shaft is rotatably connected between the left and right small wheels. A column, large wheels are provided on both sides of the rotating column, a separation mechanism is rotatably connected between the large wheels, a cylindrical seat is provided on the front left side of the base, a motor is provided on the top of the cylindrical seat, a fixed rod is connected to the left side of the motor, the bottom end of the fixed rod is connected to the front left side of the base, a flat belt is wound around the middle part of the output shaft of the motor and the left side of the rotating column, a plate is provided on the middle left side of the base, a collecting mechanism is provided on the left side of the top of the plate, gears are connected to the front end of the collecting mechanism and the right side of the output shaft of the motor, the two gears are meshed, a collecting frame is provided on the left side of the top of the plate, and the collecting frame is located at the lower side of the collecting mechanism.

[0004] The general structural principle of the green plum leaf separation device in this invention patent is as follows: start the motor, fix the motor with a cylindrical seat and a fixed rod, and the output shaft of the motor drives the gear on the left to rotate. Due to the meshing of the two gears, the rotation of the gear on the left drives the rotation of the gear on the right, and the gear on the right drives the collecting mechanism and the flat belt to rotate. The flat belt drives the rotating column to rotate, and the rotating column drives the small wheel and the large wheel to rotate. The large wheel drives the separation mechanism to rotate. At this time, the fruit farmer pours the green plum leaf mixture from the right side of the separation mechanism, and the green plum leaves are broken up and separated in the separation mechanism. The broken green plum leaves roll from the left side of the separation mechanism to the collection mechanism due to gravity, and the leaves are manually removed. Through the collection mechanism, the green plum fruit moves to the left and finally falls into the collection frame on the right side of the top of the plate. The fruit farmer takes the green plum fruit out of the collection frame to achieve the effect of quickly separating the green plum fruit leaves. After the separation of the green plum fruit leaves is completed.

[0005] However, in actual use, the green plum fruit and leaf separation device still has at least the following two shortcomings, in other words, which are the technical problems to be solved by the present invention.

[0006] 1. In the separation device, the structure for completely separating the fruit and the leaves is a water tank and a leaf separation plate. This separation method will make the leaves wet and has an upper limit on the amount of leaf accumulation. The leaves need to be taken out regularly, so the practicality is poor.

[0007] 2. The separation mechanism is cylindrical, and leaves accidentally accumulated inside need to be removed, which is also very troublesome.

[0008] Therefore, in summary, a fruit and leaf separation device is now provided which can separate leaves that have fallen off the fruit from the fruit in a simpler and more efficient manner. Summary of the invention

[0009] The present invention provides a separation device for picking fruits, and its structure is as follows: 1. Two inclined plates are arranged at intervals, and the gap is smaller than the maximum diameter of the fruit. The fruit rolls into the fruit frame along the inclined plate under gravity, and the leaves fall from the gap between the two inclined plates. The separation of the fruit and leaves is simpler and more efficient, and without obstruction of the field of vision, the operation feedback is timely, which is convenient for maintenance, and the separation of the fruit and leaves is more convenient and rapid; 2. A toggle rod unit engaged with a bidirectional conveyor belt unit drives the toggle rod unit at the lower end of the inclined plate to rotate when the packing box moves forward or backward. The periodic lifting of the toggle rod unit causes the inclined plate to swing up and down, thereby shaking off the leaves and impurities on the inclined plate, and the cleaning effect is better.

[0010] The technical solution adopted by the present invention to solve the above-mentioned problem is: a separation device for fruit picking, the structure of which includes a base plate, and also includes two inclined plates arranged on the base plate and used for rolling fruits onto the upper surface and dropping leaves at the gaps, a bidirectional conveyor belt unit arranged on the base plate and used for installing and removing fruit frames, and a toggle rod unit arranged on the base plate and connected to the bidirectional conveyor belt unit, and used for lifting the inclined plates when the fruit frames are installed and removed to drop the leaves remaining on the inclined plates.

[0011] A further preferred technical solution is that the bidirectional conveyor belt unit includes an inverted L-shaped support block arranged on the base plate, a cantilevered mounting plate arranged on the inverted L-shaped support block, a driving gear and a driven gear respectively inserted into the two ends of the cantilevered mounting plate, a conveying chain meshing the driving gear and the driven gear, and a forward and reverse motor arranged on the base plate and used to rotate the driving gear.

[0012] A further preferred technical solution is that the toggle lever unit includes a support column arranged on the base plate, a rotating shaft arranged on the support column, a rotating gear arranged on the rotating shaft, an additional gear arranged on the driven gear output shaft, and a transmission chain meshing with the rotating gear and the additional gear, and an extension rod arranged on the rotating shaft and used to rotate and toggle the inner side of the inclined plate.

[0013] A further preferred technical solution is that it also includes high supporting posts and low supporting posts which are arranged on the bottom plate and are used to tilt the inclined plate toward the fruit frame.

[0014] A further preferred technical solution is that it also includes an articulated seat unit which is arranged on the supporting high legs and the supporting low legs and is used to connect the inclined plate.

[0015] A further preferred technical solution is that the side edges of the inclined plate close to the supporting high columns and the supporting low columns are higher than the side edges close to the supporting columns.

[0016] A further preferred technical solution is that the articulated seat unit includes a perforated hinged plate arranged on the inclined plate, a perforated plug-in slot plate arranged on the supporting high column and / or the supporting low column, and a pin arranged on the perforated plug-in slot plate and used for plugging the perforated hinged plate.

[0017] A further preferred technical solution is that the toggle lever unit further comprises an inclined toggle plate which is arranged on the extension rod and is used for rotating and fitting into the bottom end of the inclined plate.

[0018] A further preferred technical solution is that the bidirectional conveyor belt unit also includes transport plates that are spaced apart on the conveyor chain and are used to support the fruit boxes.

[0019] A further preferred technical solution is that it also includes a front baffle plate which is arranged on the bottom plate and close to the position of the supporting high pillars and is used to prevent the fruit from rolling out. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.

[0032] As attached Figure 1-10 As shown, a separation device for picking fruits comprises a bottom plate 11, two inclined plates 1 arranged on the bottom plate 11 and used for rolling fruits a onto the upper surface and dropping leaves b at the gaps, a bidirectional conveyor belt unit 2 arranged on the bottom plate 11 and used for installing and removing fruit frames c, and a toggle lever unit 3 arranged on the bottom plate 11 and connected to the bidirectional conveyor belt unit 2 and used for dropping the leaves b remaining on the inclined plate 1 by lifting the inclined plate 1 when the fruit frames c are installed and removed.

[0033] In this embodiment, the separation device for fruit picking can be used for separation and packaging during the picking process, and can also be used for separation and packaging during fruit storage. Taking the separation and packaging during the picking process as an example, the separation device for fruit picking is arranged on the picking machine through the bottom plate 11, and the inclined plate 1 is located between the two picking rollers d. After the fruit a is picked by the picking rollers d, it is transported to the upper end of the inclined plate 1 through the transportation device. The two are inclined toward the fruit frame c, and the end close to the fruit frame c is lower than the end away from the fruit frame c, so that the fruit a can roll into the fruit frame c. The two inclined plates 1 are set with a gap, and the fruit a and the leaves b are poured in from both sides of the two inclined plates 1. The gap between the two inclined plates 1 should be smaller than the maximum diameter of the fruit a, so as to prevent the fruit a from falling from the gap, so that the fruit a rolls into the fruit frame c through the guidance of the inclined plate 1, and the leaves b slide down from the gap between the two inclined plates 1 due to gravity, so as to achieve simultaneous classification and processing of fruit and leaves separation, the fruit a enters the fruit frame c for packaging and collection, and the fallen leaves b are discharged from the gap between the two inclined plates 1.

[0034] In addition, the function of the bidirectional conveyor belt unit 2 is to drive the fruit frame c away from the inclined plate 1 when the fruit frame c is full of the fruit a, and to drive the fruit frame c close to the inclined plate 1 when the fruit frame c is empty, so as to reduce the difficulty of manual handling. To facilitate the loading and unloading of the fruit frame c during the picking process, the bidirectional conveyor belt unit 2 can be set at the rear wheel position of the walking wheel e of the picking machine, and the inclined plate 1 is located in the middle of the picking machine or at the front wheel position of the walking wheel e. Furthermore, due to the different sizes of fruits, the distance between the bidirectional conveyor belt unit 2 and the fruit frame c and the inclined plate 1 also needs to be adjusted accordingly.

[0035] In addition, the toggle lever unit 3 is arranged directly below the inclined plate 1. When the bidirectional conveyor belt unit 2 drives the fruit frame c to move forward and backward, the toggle lever unit 3 connected to the bidirectional conveyor belt unit 2 will also be subjected to a change in force, thereby causing the toggle lever unit 3 that does not interfere with the inclined plate 1 to rotate and lift up the inclined plate 1. According to the periodic change of the rotation, the inclined plate 1 is lifted back and forth, thereby shaking off the leaves b or impurities attached to the inclined plate 1, making cleaning efficient and convenient. In order to facilitate the toggle lever unit 3 to lift up the inclined plate 1, the inclined plate 1 can be made of elastic material, or can be set in the form of a movable hinge or a retractable spring sheet, so that after the toggle lever unit 3 lifts up the inclined plate 1, the inclined plate 1 can vibrate to a certain extent, and at the same time, it does not affect the fruit a in a static state from entering the fruit frame c.

[0036] Finally, as attached Figure 7 and attached Fig. 9 As shown in the figure, this is the initial state of the separation device for fruit picking. When it is necessary to separate the fruit and leaves, the bidirectional conveyor belt unit 2 is turned on to drive the fruit frame c to approach the inclined plate 1. At this time, the toggle lever unit 3 also rotates to lift and lower the inclined plate 1. Figure 8 and attached Fig.10 As shown, this is a schematic diagram of the toggle lever unit 3 shaking off the leaf b on the inclined plate 1. The inclined plate 1 is in a vibrating state, which can provide preliminary feedback on whether the separation device for fruit picking can be used normally. After the fruit frame c reaches the position where the fruit a can roll down, the bidirectional conveyor belt unit 2 is closed. At this time, the toggle lever unit 3 stops rotating and lifts up, and returns to the initial state. The inclined plate 1 is in a stationary state, and then the fruit a and the leaf b are poured in from both sides of the upper end of the inclined plate 1. The fruit a rolls into the fruit frame c, and the leaf b falls out from the gap between the two inclined plates 1. After the fruit frame c is full, the fruit a is stopped from being poured in, and the bidirectional conveyor belt unit 2 is opened, so that the fruit frame c is away from the inclined plate 1. At this time, the toggle lever unit 3 moves synchronously and lifts up the inclined plate 1 to shake off the leaf b. While cleaning, prevent the leaf from blocking the gap. If you need to continue collecting the fruit a, repeat the operation.

[0037] The bidirectional conveyor belt unit 2 includes an inverted L-shaped support block 201 arranged on the base plate 11, a cantilevered mounting plate 202 arranged on the inverted L-shaped support block 201, a driving gear 203 and a driven gear 204 respectively inserted at both ends of the cantilevered mounting plate 202, a conveying chain 205 that meshes the driving gear 203 and the driven gear 204, and a forward and reverse motor 206 arranged on the base plate 11 and used to rotate the driving gear 203.

[0038] In this embodiment, the inverted L-shaped support block 201 is used to support and raise the cantilever mounting plate 202, the driving gear 203 and the driven gear 204 are rotatably connected to the two ends of the cantilever mounting plate 202, and two gears are protruding from the two ends of the rod, located on the two sides of the cantilever mounting plate 202, and the conveying chain 205 meshes and connects the protruding driving gear 203 and the driven gear 204, the cantilever mounting plate 202 is wrapped by the conveying chain 205, and the bottom end of the cantilever mounting plate 202 is at a certain distance from the bottom plate 11, which does not affect the rotation of the conveying chain 205, and the driven gear 204 is located at one end close to the toggle rod unit 3. The forward and reverse motor 206 is an existing motor that can drive the driving gear 203 to rotate clockwise or counterclockwise, thereby driving the fruit box c on the conveying chain 205 to move forward or backward.

[0039] The toggle lever unit 3 includes a support column 301 arranged on the base plate 11, a rotating shaft 302 arranged on the support column 301, a rotating gear 303 arranged on the rotating shaft 302, an additional gear 304 arranged on the output shaft of the driven gear 204, and a transmission chain 305 meshing the rotating gear 303 and the additional gear 304, and an extension rod 306 arranged on the rotating shaft 302 and used to rotate and toggle the inner side of the tilting plate 1.

[0040] In this embodiment, the support column 301 is arranged directly below the inclined plate 1 and close to the gap between the two inclined plates 1. In the initial state, the support column 301 can support the inclined plate 1. The distance between the two inclined plates 1 can be adjusted by adjusting the length of the inclined plate 1. The rotating shaft 302 is installed with the rotating gear 303 and can rotate freely on the support column 301 along with the rotating gear 303. After the driving gear 203 rotates, it drives the driven gear 204 and the additional gear 304 to rotate. The transmission chain 305 on the additional gear 304 drives the rotating gear 303 to rotate. The extension rod 306 on the rotating shaft 302 will also rotate along with the rotating gear 303, so that the inclined plate 1 can be intermittently lifted, so as to achieve the effect of shaking off the leaves b attached to the inclined plate 1. The extension rod 306 can be arranged at intervals around the rotating gear 303 to increase the shaking frequency, and the extension rods 306 of different lengths can also be set to change the shaking amplitude of the inclined plate 1.

[0041] It also includes a supporting high post 4 and a supporting low post 5 which are arranged on the bottom plate 11 and are used to tilt the inclined plate 1 toward the fruit frame c.

[0042] In this embodiment, the supporting high legs 4 and the supporting low legs 5 make the inclined plate 1 tilt toward the end of the fruit frame c, increasing the possibility that the fruit a can smoothly enter the fruit frame c. The gap parallel to the two inclined plates 1 is the front view angle, and the gap perpendicular to the two inclined plates 1 is the side view angle. Fig. 9 and 10 As shown, the fruit frame c is arranged at one end close to the supporting low foot column 5.

[0043] It also includes an articulated seat unit 6 which is arranged on the supporting high legs 4 and the supporting low legs 5 and is used to connect the inclined plate 1 .

[0044] In this embodiment, the hinge seat unit 6 enables the two tilting plates 1 to open and close, thereby facilitating the toggle lever unit 3 to toggle the tilting plates 1. Figure 3 As shown, the toggle lever unit 3 is staggered with the supporting high legs 4 and the supporting low legs 5 to ensure the stable use of the tilting plate 1 .

[0045] The side of the inclined plate 1 close to the supporting high pillars 4 and the supporting low pillars 5 is higher than the side close to the supporting pillars 301 .

[0046] In this embodiment, as shown in the attached Figure 7 and attached Figure 8 As shown, the support column 301 supports one end of the inclined plate 1 close to the gap, and the side of the inclined plate 1 close to the supporting high legs 4 and the supporting low legs 5 is higher than the side close to the support column 301, so that the fallen fruits converge at the gap between the two inclined plates 1 and flow into the fruit frame c, which can prevent the fruits a from rolling out to both sides to a certain extent.

[0047] The articulated seat unit 6 includes a perforated hinge plate 601 arranged on the inclined plate 1, a perforated plug-in slot plate 602 arranged on the supporting high leg 4 and / or the supporting low leg 5, and a pin 603 arranged on the perforated plug-in slot plate 602 and used for plugging the perforated hinge plate 601.

[0048] In this embodiment, the hinged plate with holes 601 and the slotted plate with holes 602 are hinged by the pin shaft 603, so that the tilting plate 1 can swing on the supporting high legs 4 and the supporting low legs 5, thereby not affecting the toggling effect of the toggle lever unit 3.

[0049] The toggle lever unit 3 further includes an inclined toggle plate 307 which is arranged on the extension rod 306 and is used for rotating and fitting with the bottom end of the inclined plate 1 .

[0050] In this embodiment, the tilting toggle plate 307 fits with the bottom end of the tilting plate 1 after being lifted up, thereby increasing the force-bearing area, improving vibration stability, and reducing scratches on the tilting plate 1 by the extension rod 306 .

[0051] The bidirectional conveyor belt unit 2 further includes a transport plate 207 which is spaced apart on the conveyor chain 205 and is used to support the fruit boxes c.

[0052] In this embodiment, the transport plate 207 is used to place the fruit box c, so that the placement of the fruit box c is more stable, and the conveying chain 205 can be protected at the same time.

[0053] It also includes a front baffle plate 7 which is arranged on the bottom plate 11 and close to the supporting high pole 4 and is used to prevent the fruit a from rolling out.

[0054] In this embodiment, the fruit frame c is placed near one end of the supporting low foot column 5, and the front baffle plate 7 is used to enclose the separation space between the two inclined plates 1 to prevent the fruit a from rolling out from the end near the supporting high foot column 4 when poured in. At the same time, a fan blowing toward the inclined plate 1 can be provided on the front baffle plate 7 to increase the efficiency of fruit and leaf separation.

[0055] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the present invention.
