[0055] The following is combined with Figures 1-6 This invention describes a fruit branch separation and crushing device based on photoelectric sensing detection, according to an embodiment of the present invention.

[0056] Figure 1 A side view of the fruit branch separation and crushing device based on photoelectric sensing detection provided in an embodiment of the present invention is illustrated. Figure 2 This example illustrates one of the structural schematic diagrams of the fruit branch separation and crushing device based on photoelectric sensing detection provided in an embodiment of the present invention after the support frame has been removed. Figure 6 Example four illustrates the structure of the fruit branch separation and crushing device based on photoelectric sensing detection provided in this embodiment of the invention after removing the support frame, as shown in the example. Figure 1 , Figure 2 and Figure 6 As shown, the fruit branch separation and crushing device based on photoelectric sensing detection includes a frame 100, a fruit branch separation component 200, a control component, a branch conveying component 300, and a branch crushing component 400. The frame 100 is used to integrate the above components together, which improves the integration of the fruit branch separation and crushing device and reduces the size of the fruit branch separation and crushing device.

[0057] The fruit branch separation component 200 includes a linear reciprocating drive assembly 210, a guide rail 220, a comb tooth assembly, and a sensor assembly. The comb tooth assembly includes a baffle 240 and multiple comb teeth 230, which are spaced apart on one side of the baffle 240. The comb teeth 230 have a rod-shaped structure with a circular cross-section and a cylindrical outer surface to avoid damaging the fruit during the fruit branch separation process. To further reduce damage to the fruit during the movement of the comb teeth 230, a flexible sleeve made of rubber or silicone is fitted onto the outer surface of the comb teeth 230. The guide rail 220 is mounted vertically on the frame 100 and is tilted at a certain angle. The baffle 240 slides against the guide rail 220 via a slider. The sensor assembly is mounted on the baffle 240. The linear reciprocating drive assembly 210 is connected to the slider and the frame 100.

[0058] The fruit branch separation component 200 works by clamping the upper end of the branch between the first flexible roller 321 and the second flexible roller 322, and the lower end of the branch between two adjacent comb teeth 230. The fruit hangs naturally below the comb teeth 230 under the influence of gravity. When the linear reciprocating drive assembly 210 drives the baffle 240 downwards, the comb teeth 230 push the fruit downwards, separating the fruit from the branch. Since multiple branches and fruits can be separated at once, this significantly improves separation efficiency compared to existing separation technologies.

[0059] The control unit is electrically connected to the sensor assembly and the linear reciprocating drive assembly 210. The sensor assembly sends an electrical signal to the control unit when it detects fruit beneath a predetermined number of comb teeth 230. The control unit processes the electrical signal and sends a control command to the linear reciprocating drive assembly 210. Upon receiving the control command, the linear reciprocating drive assembly 210 drives the baffle 240 to move up and down reciprocally, thereby separating the fruit from the branch through the comb teeth 230. The control unit includes a controller or a control circuit board and is housed within the electrical control box 110.

[0060] The branch conveying component 300 is disposed on the frame 100 and located above the fruit branch separating component 200. The branch crushing component 400 is disposed on the frame 100. The branch conveying component 300 is used to clamp the branches and convey the branches separated from the fruit to the branch crushing component 400; the branch crushing component 400 is used to crush the branches.

[0061] The fruit-branch separation and crushing device based on photoelectric sensing provided in this embodiment of the invention can complete the fruit-branch separation of various fruits, and has the advantages of simple structure and high working efficiency. By setting a sensor component on the baffle 240, when the sensor component detects that there is fruit under a predetermined number of comb teeth 230, the control component controls the linear reciprocating drive component 210 to drive the baffle 240 to move up and down reciprocally, which can effectively prevent operator injury and improve the safety of the equipment.

[0062] In one embodiment of the present invention, the baffle 240 has a rectangular plate structure. The baffle 240 provides a mounting base for the comb teeth 230 and, together with the baffle 240, provides a clamping space for the branches, so that the branches are clamped between two adjacent comb teeth 230.

[0063] In one embodiment of the present invention, the baffle 240 is inclined in the vertical direction, and the baffle 240 forms an acute angle with the vertical plane. The angle between the baffle 240 and the horizontal plane is specifically set according to actual needs. A fixing seat 250 is provided on one side of the baffle 240 and is detachably connected to the baffle 240. Specifically, the fixing seat 250 and the baffle 240 are connected by bolts. Of course, the fixing seat 250 and the baffle 240 can also be connected by snaps or other fasteners. The fixing seat 250 has a rectangular plate structure and extends in the horizontal direction. Multiple comb teeth 230 are spaced apart on the fixing seat 250 along the length direction of the fixing seat 250.

[0064] In one embodiment of the present invention, the comb teeth 230 form an acute angle with the horizontal plane, and are perpendicular to the fixing base 250 and the baffle 240. The distance between two adjacent comb teeth 230 is equal, and the distance between two adjacent comb teeth 230 is less than the outer diameter of the fruit. In this embodiment, the distance between two adjacent comb teeth 230 is about 0.5 cm. Of course, the distance between two adjacent comb teeth 230 is not limited to this, and is determined according to the type of fruit to be separated and the thickness of the branches.

[0065] In one embodiment of the present invention, the sensor assembly includes a photoelectric sensor. Multiple photoelectric sensors are arranged along the length of the baffle 240. The photoelectric sensors are located below the comb teeth 230. Each photoelectric sensor may correspond to one comb tooth 230, or each photoelectric sensor may correspond to two, three or more comb teeth 230.

[0066] It should be noted that there are several possibilities for the presence of fruit under the predetermined number of comb teeth 230. It could be that fruit is present under one-third of the total number of comb teeth 230, or it could be present under one-half of the total number of comb teeth 230.

[0067] In one embodiment of the present invention, the comb teeth 230 are welded to the fixing base 250 or integrally formed.

[0068] In one embodiment of the present invention, the comb tooth assembly further includes a base plate located between the fixing seat 250 and the baffle 240, and the base plate and the baffle 240 are connected by bolts. A limiting portion is provided at one end of the comb tooth 230 near the baffle 240. The fixing seat 250 is provided with multiple strip-shaped through holes extending along the length of the fixing seat 250. One end of the comb tooth 230 near the baffle 240 passes through the strip-shaped through holes. The limiting portion is located between the base plate and the fixing seat 250. When the bolts are tightened, the limiting portion is clamped between the base plate and the fixing seat 250, thereby fixing the comb tooth 230. When the bolts are loosened, the comb tooth 230 can change position along the length of the strip-shaped through holes, thereby changing the distance between two adjacent comb teeth 230. With this structural design, the distance between two adjacent comb teeth 230 can be adjusted as needed, making the comb tooth assembly applicable to different types of fruits and enhancing the versatility of the fruit branch separation and crushing device.

[0069] In one embodiment of the present invention, two guide rails 220 are provided, arranged parallel and spaced apart, located on the other side of the baffle 240, and parallel to the baffle 240. Two sliders are provided, with each of the two guide rails 220 and the two sliders corresponding to each other in a sliding engagement, and each of the two sliders being connected to one end of the baffle 240. Alternatively, the baffle 240 can also be positioned between the two guide rails 220.

[0070] Furthermore, in order to precisely control the movement distance of the baffle 240, a position sensor can be installed on the guide rail 220. The position sensor is electrically connected to the control component. The position sensor senses the position of the baffle 240, thereby precisely controlling the movement distance of the baffle 240.

[0071] In one embodiment of the present invention, the linear reciprocating drive assembly 210 includes a cylinder, the cylinder body of which is connected to the frame 100, and the cylinder's extension rod is connected to the slider. When the cylinder's extension rod extends from the cylinder body, the baffle 240 moves downward; when the cylinder retracts from the cylinder body, the baffle 240 moves upward. Of course, the specific type of the linear reciprocating drive assembly 210 is not limited to a cylinder; it can also be a hydraulic cylinder, a linear motor, or other linear reciprocating drive mechanism. When the linear reciprocating drive assembly 210 is a hydraulic cylinder, the cylinder body is connected to the frame 100, and the hydraulic cylinder's extension rod is connected to the slider.

[0072] In one embodiment of the invention, two cylinders are provided, arranged parallel and spaced apart, and parallel to the corresponding guide rails 220. The cylinder body is connected to the frame 100 via a connector, specifically, the connector is sleeved onto the cylinder body and fixed with a nut. Further, the connector has a strip-shaped mounting hole extending vertically, and the frame 100 is connected to the connector via a fixing bolt within the strip-shaped hole. By changing the position of the fixing bolt within the strip-shaped hole, the position of the cylinder can be changed, thereby changing the maximum movement position of the baffle 240 to accommodate branches of different sizes.

[0073] It should be noted that, in order to prevent the branches from being too long or too short, resulting in poor separation effect, other pruning equipment can be used to pre-cut the branches to a predetermined length to better adapt to the fruit branch separation and crushing device of the present invention. The length of the branches is specifically determined according to the distance between the flexible roller group 320 and the lowest position of the comb teeth 230.

[0074] In one embodiment of the present invention, Figure 4 This is illustrated in the third schematic diagram of the fruit branch separation and crushing device based on photoelectric sensing detection provided in this embodiment of the invention after the support has been removed. Figure 5 yes Figure 4 A magnified view of the local structure at point A, as shown below. Figure 4 and Figure 5 As shown, the branch conveying component 300 includes a conveying trough 310, a conveying assembly, a first drive assembly 330, and a first transmission assembly 340. The conveying trough 310 is connected to the frame 100 and is located above the baffle 240.

[0075] The conveying assembly includes multiple flexible rollers 320, which are located between the conveying trough 310 and the baffle 240. The flexible rollers 320 are horizontally spaced on the frame 100, and their horizontal arrangement is less than or equal to the width of the conveying trough 310. In this embodiment, the frame 100 has four flexible rollers 320; however, the number of flexible rollers 320 is not limited to this and is determined based on the width of the conveying trough 310. The distance between two adjacent flexible rollers 320 can be the same or different.

[0076] The flexible roller assembly 320 includes a first flexible roller 321 and a second flexible roller 322. Both rollers are made of flexible materials, such as rubber, silicone, or high-density sponge. Using rollers made of flexible materials offers two advantages in conveying branches: firstly, the flexible rollers increase the friction between the rollers and the branches, preventing the branches from sliding downwards and falling; secondly, because the flexible rollers are easily deformed under pressure, they can accommodate branches of different diameters.

[0077] The first flexible roller 321 and the second flexible roller 322 of the same group are arranged at intervals in the horizontal direction. The distance between the first flexible roller 321 and the second flexible roller 322 is specifically determined according to the diameter of the branch. The first flexible roller 321 and the second flexible roller 322 are rotatably connected to the frame 100. Specifically, the first flexible roller 321 is connected to the first drive shaft 344, and the first drive shaft 344 is rotatably engaged with the frame 100. Similarly, the second flexible roller 322 is connected to the second drive shaft 345, and the second drive shaft 345 is rotatably engaged with the frame 100.

[0078] Furthermore, a mounting portion is provided at the end of the first drive shaft 344, and a mounting hole is provided inside the first flexible roller 321, which is fitted onto the mounting portion. When the first flexible roller 321 wears, it can be removed and a new flexible roller can be installed. To prevent relative rotation between the first flexible roller 321 and the first drive shaft 344, the cross-section of the mounting portion is non-circular, and the cross-sectional shape of the mounting hole is the same as that of the mounting portion.

[0079] The first transmission assembly 340 is connected to the first drive assembly 330 and a plurality of flexible rollers 320. The first transmission assembly 340 is used to transmit the power output by the first drive assembly 330 to the plurality of flexible rollers 320 to drive the plurality of flexible rollers 320 to rotate. The first drive assembly 330 is used to drive the first flexible roller 321 and the second flexible roller 322 of the same group to rotate in opposite directions through the first transmission assembly 340 to convey the branches into the conveying trough 310.

[0080] It should be noted here that, as Figure 5 As shown, the first flexible roller 321 and the second flexible roller 322 rotating in opposite directions means that the first flexible roller 321 and the second flexible roller 322 rotating in directions away from each other, that is, the first flexible roller 321 rotating in the direction of arrow A and the second flexible roller 322 rotating in the direction of arrow B.

[0081] In one embodiment of the present invention, such as Figure 4 and Figure 5As shown, the end of the conveying trough 310 near the branch crushing component 400 slopes downwards, and the bottom surface of the conveying trough 310 is an inclined surface that slopes downwards toward the branch crushing component 400. When the branch conveying component 300 conveys the branch into the conveying trough 310, the branch can automatically slide downwards under the action of gravity and then enter the branch crushing component 400, that is, enter the inner wall of the housing 410.

[0082] In one embodiment of the present invention, such as Figure 4 and Figure 5 As shown, the central axis of the first flexible roller 321 and the central axis of the second flexible roller 322 both form an acute angle with the horizontal plane. With this arrangement, after the branch passes through the flexible roller group 320, the branch will automatically tilt towards the conveying trough 310. After the branch has completely passed through the flexible roller group 320, the branch will fall into the conveying trough 310 under the action of gravity.

[0083] Furthermore, the end of the conveying trough 310 near the flexible roller assembly 320 is provided with a horizontal surface. The width of the horizontal surface is smaller than the width of the inclined surface, meaning that most of the conveying trough 310 is in a downward inclined state, with only a small portion in a horizontal state. During the conveying process of the flexible roller assembly 320, the branches initially move upwards. When the branches reach their highest point, they completely pass through the flexible roller assembly 320. Under the influence of gravity, the branches tilt into the conveying trough 310, with the tail end on the horizontal surface and the head end on the inclined surface. Since most of the branches are on the inclined surface, they can slide downwards under gravity and enter the branch crushing component 400.

[0084] In one embodiment of the present invention, such as Figure 2 As shown, the branch conveying component 300 also includes a roller frame 370 and multiple rollers 360. The roller frame 370 is disposed within the conveying trough 310 and provides an installation base for the rollers 360. Alternatively, to simplify the structure, the roller frame 370 may be omitted, and the two ends of the rollers 360 may be rotatably connected to the sidewalls of the conveying trough 310. The multiple rollers 360 are arranged at intervals along the length of the conveying trough 310, with their two ends rotatably connected to the roller frame 370. Some of the rollers 360 are arranged sequentially along an inclined plane, while the remaining rollers are arranged sequentially along a horizontal plane. Due to the rotatable engagement between the rollers 360 and the roller frame 370, branches falling on the rollers 360 can slide downwards under gravity, reducing resistance during the downward movement of the branches.

[0085] In one embodiment of the present invention, such as Figure 4 and Figure 5As shown, the first transmission assembly 340 includes a first sprocket 341, a second sprocket 342, multiple first transmission shafts 344, multiple second transmission shafts 345, a second chain 346, a third chain 348, a first gear 350, and a second gear 351. The first sprocket 341 is connected to the shaft of the first drive assembly 330. Specifically, the first sprocket 341 is sleeved on the shaft of the first drive assembly 330, which is a motor. The motor housing is bolted to the frame 100. The second sprocket 342 is connected to the first sprocket 341 via a first chain 343.

[0086] Multiple first drive shafts 344 are horizontally spaced on the frame 100, and are rotatably connected to the frame 100. Each of the multiple first drive shafts 344 is connected to a corresponding number of first flexible rollers 321. A second sprocket 342 is connected to one of the first drive shafts 344. Specifically, the second sprocket 342 is connected to a first drive shaft 344 located near the first drive assembly 330. This connection method shortens the length of the first chain 343 and improves transmission efficiency. To prevent the first chain 343 from wobbling during transmission, the second sprocket 342 and the first sprocket 341 are in the same plane. In this embodiment, the outer diameter of the second sprocket 342 is equal to the outer diameter of the first sprocket 341.

[0087] Multiple second drive shafts 345 are horizontally spaced on the frame 100, rotatably connected to the frame 100, and each second drive shaft 345 is correspondingly connected to a multiple second flexible rollers 322. A second chain 346 connects each first drive shaft 344 to a second sprocket 342. Each first drive shaft 344 is provided with a third sprocket 347, and the multiple third sprockets 347 are in the same plane. Each first drive shaft 344 meshes with the second chain 346 through the third sprocket 347. Similarly, a fourth chain 443 connects each second drive shaft 345, and each second drive shaft 345 is provided with a fourth sprocket 349, which meshes with the third chain 348.

[0088] The first gear 350 is connected to the first drive shaft 344. Specifically, the first gear 350 is sleeved on the first drive shaft 344. The second gear 351 meshes with the first gear 350 and is connected to a second drive shaft 345. Specifically, the second gear 351 is sleeved on a second drive shaft 345 near the first drive assembly 330. With this connection method, only two gears need to mesh to transmit the power on the second sprocket 342 to each second drive shaft 345, effectively simplifying the structure of the transmission mechanism and reducing production costs.

[0089] It should be noted that the outer diameter and number of teeth of the second gear 351 are the same as those of the first gear 350. This way, when the second sprocket 342 rotates, the first gear 350 and the second gear 351 can rotate synchronously, ensuring that the first drive shaft 344 and the second drive shaft 345 rotate synchronously. Ultimately, this causes the first flexible roller 321 and the second flexible roller 322 to rotate synchronously, preventing the branches from deflecting to the left or right.

[0090] It should also be noted that the specific structure of the first transmission component 340 is not limited to a combination of gears, chains and sprockets, but can also be a combination of belts and pulleys.

[0091] Working principle of branch conveying component 300:

[0092] When the first drive assembly 330 drives the first sprocket 341 to rotate, the first sprocket 341 drives the second sprocket 342 to rotate via the first chain 343. The second sprocket 342 drives the first gear 350 to rotate, and the first gear 350 drives the second gear 351 to rotate. During the rotation of the first gear 350, the second chain 346 is driven to rotate. The second chain 346 drives the first drive shaft 344 to rotate via each third sprocket 347. Each first drive shaft 344 drives the corresponding first flexible roller 321 to rotate. During the rotation of the second gear 351, the third chain 348 is driven to rotate. The third chain 348 drives the second drive shaft 345 to rotate via each fourth sprocket 349. Each second drive shaft 345 drives the corresponding second flexible roller 322 to rotate. Since the first gear 350 and the second gear 351 are meshed, the first flexible roller 321 and the second flexible roller 322 both rotate in a direction away from each other.

[0093] In one embodiment of the present invention, Figure 3 This is an example of a second schematic diagram of the structure of the fruit branch separation and crushing device based on photoelectric sensing detection provided in an embodiment of the present invention after the support has been removed. Figure 3 As shown, the branch shredding component 400 includes a housing 410, at least one cutter roller assembly 430, a second transmission assembly 440, and a second drive assembly 450. The housing 410 provides a receiving cavity for mounting the cutter roller assembly 430. The housing 410 is connected to the frame 100 and is rectangular in shape. A feed inlet is provided at the top of the housing 410, and a discharge outlet 420 is provided at the bottom. The discharge outlet 420 is inclined downwards to facilitate automatic discharge of the shredded branches.

[0094] A cutter roller assembly 430 is disposed within the housing 410. In this embodiment, one cutter roller assembly 430 is provided, but two, three, or more cutter roller assemblies 430 can also be provided. Each cutter roller assembly 430 includes two parallel cutter rollers 431, symmetrically arranged, with both ends of each roller 431 rotatably connected to the housing 410. A second transmission assembly 440 is connected to the cutter rollers 431, and a second drive assembly 450 is connected to the second transmission assembly 440. The second drive assembly 450 drives the cutter rollers 431 to rotate via the second transmission assembly 440 to shred the branches. The second drive assembly 450 is a motor; to increase the output torque of the motor, a speed reducer can also be provided between the motor and the second transmission assembly 440.

[0095] In one embodiment of the present invention, in order to facilitate the connection between the cutter roller 431 and the second transmission component 440, one end of the cutter roller 431 is provided with a connecting shaft, and the connecting shaft is connected to the cutter roller 431 by a spline or integrally formed.

[0096] In one embodiment of the present invention, the second transmission assembly 440 includes a fifth sprocket 441, a sixth sprocket 442, a fourth chain 443, a third gear 444, and a fourth gear 445. The fifth sprocket 441 is connected to the shaft of the second drive assembly 450, and the sixth sprocket 442 is connected to the connecting shaft. Specifically, the sixth sprocket 442 is sleeved on the connecting shaft and fixed by a spline, and the sixth sprocket 442 is connected to the fifth sprocket 441 by the fourth chain 443. The third gear 444 is sleeved on one end of a cutter roller 431, and the fourth gear 445 is sleeved on one end of another cutter roller 431, with the third gear 444 meshing with the fourth gear 445. To reduce the influence of branches on the third gear 444 and the fourth gear 445, partitions are provided on the outer periphery of the third gear 444 and the fourth gear 445 to encapsulate them internally. Similarly, the fifth sprocket 441 and the sixth sprocket 442 are also encapsulated by partitions.

[0097] It should be noted that the specific structure of the second transmission component 440 is not limited to a combination of gears, chains and sprockets, but can also be a combination of belts and pulleys.

[0098] Working principle of the branch crushing component 400:

[0099] When the second drive assembly 450 rotates, it drives the fifth sprocket 441 to rotate. The fifth sprocket 441 drives the sixth sprocket 442 to rotate via the fourth chain 443. The sixth sprocket 442 drives one cutter roller 431 to rotate via the connecting shaft. The rotating cutter roller 431 drives another cutter roller 431 to rotate via the third gear 444 and the fourth gear 445. Because the third gear 444 and the fourth gear 445 are meshed, the two cutter rollers 431 rotate in a direction that brings them closer to each other. The branches that enter the housing 410 can be crushed by the action of the two cutter rollers 431. The crushed branches are discharged through the discharge port 420.

[0100] In one embodiment of the present invention, the second drive assembly 450 is disposed on one side of the housing 410, the second transmission assembly 440 is located at one end of the housing 410, and the fruit branch separating component 200 is located at the other end of the housing 410. This arrangement effectively improves the compactness of the fruit branch separating and crushing device, reduces the space occupied by the device, and facilitates transportation and use.

[0101] In one embodiment of the present invention, the fruit branch separating and crushing device further includes an electrical control box 110, with control components disposed inside the electrical control box 110, which is located below the first driving component.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
