[0053] In the description of this application, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. 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.

[0054] Refer to Figure 1 , which shows one of the structural diagrams of a collection device provided by an embodiment of this application for a harvester; refer to Figure 2 , which shows another structural diagram of a collection device provided by an embodiment of this application for a harvester; refer to Figure 3 , which shows a schematic diagram of the connection of each component in a collection device provided by an embodiment of this application for a harvester.

[0055] As Figures 1 to 3As shown, the collecting device used on the harvester of the present application includes: a bracket 10, a collecting basket 20 and two placing plates 30; the two placing plates 30 are rotatably connected to the bracket 10 respectively, and switch between a closed state and an open state; a sliding member is provided on the first side and the second side of the collecting basket 20 respectively, and a sliding part is provided on each placing plate 30 respectively, and one sliding member corresponds to one sliding part, wherein the first side of the collecting basket 20 is opposite to the second side of the collecting basket 20, and the sliding member is arranged in a vertical direction; when the two placing plates 30 are in a closed state, the two placing plates 30 are horizontal and flush, and are used to place the collecting basket 20 thereon, wherein each sliding member is aligned with the corresponding sliding part in the vertical direction; when the two placing plates 30 are in an open state, the two placing plates 30 are respectively rotated from a horizontal state to a vertical state, and each sliding member is respectively embedded in the corresponding sliding part, so that each sliding member is respectively slidably matched with the corresponding sliding part, and the collecting basket 20 full of vegetables slides to the ground in a vertical direction. In this way, the need for manual transport of the collection baskets full of vegetables to the field is avoided, labor costs are saved, transportation efficiency is improved, and injuries due to improper operation when manual transport of the collection baskets near a running harvester can be avoided.

[0056] It should be noted that the collection basket 20 of the present application is used for a harvester for harvesting leafy vegetables, including spinach, lettuce, Chinese cabbage, water spinach, etc. The bracket 10 on the collection basket 20 can be installed on the frame of the harvester, or it can be a part of the structure of the harvester frame. Take a harvester for harvesting spinach in an unordered manner as an example. The harvester includes a frame, and a weeding device, a cutting device, a transmission device, and a collection device installed on the frame. When the spinach harvester is moving, the weeding device presses the spinach toward the cutting device to cut the spinach; the cut spinach falls onto the transmission device, and with the transmission of the transmission device, it falls into the collection basket 20 of the collection device, completing the harvesting and collection of the spinach.

[0057] like Figure 1 As shown, when the two placement plates 30 are in a closed state, the two placement plates 30 are in a horizontal state, and the two placement plates 30 are flush so that the collection basket 20 can be placed thereon, wherein, along the vertical direction, that is, the up and down direction, the sliding member arranged on the first side of the collection basket 20 is aligned with the sliding portion arranged on one placement plate 30, and the sliding member arranged on the second side of the collection basket 20 is aligned with the sliding portion arranged on the other placement plate 30, that is, each sliding member is just located above the sliding portion; based on this, when the collection device is moved from Figure 1 The status switches to Figure 2When in the state where the two placement plates 30 rotate from the horizontal state to the vertical state relative to the bracket 10 respectively, that is, the two placement plates 30 are switched from the closed state to the open state. At this time, each sliding member is exactly embedded in the corresponding sliding portion respectively, so that each sliding member is slidably engaged with the corresponding sliding portion, thereby enabling one placement plate 30 to be slidably connected to the first side of the collection basket 20, and the other placement plate 30 to be slidably connected to the second side of the collection basket 20. In this way, the collection basket full of vegetables can slide down to the ground. Among them, the horizontal state is parallel to the reference horizontal direction in the figure. In practice, the ground of the field is approximately regarded as a horizontal plane, and the two placement plates 30 are parallel to the ground of the field. The vertical state is parallel to the reference vertical direction in the figure.

[0058] It should be noted that since the sliding members are arranged in the vertical direction, when the two placement plates 30 are in the vertical state, the sliding portions on the placement plates 30 are also in the vertical state. In this way, each sliding member can be slidably engaged with the corresponding sliding portion, so that the collection basket 20 can slide down vertically to the ground.

[0059] As Figure 1 and Figure 2 shown, two sliding members are respectively arranged on the first side and the second side of the collection basket 20, and two sliding portions are also respectively arranged on each placement plate 30. In practice, the number of sliding members and sliding portions can be 1, 2, 3, etc. This embodiment does not limit the specific number of their settings, as long as one sliding member corresponds to one sliding portion.

[0060] In addition, in the embodiment of the present application, as Figure 1 and Figure 2 shown, the sliding member can be a slider 21, and the sliding portion can be a chute 31; when the two placement plates 30 are in the closed state, along the vertical direction, each slider 21 is aligned with the corresponding chute 31 respectively; when the two placement plates 30 are in the open state, each slider 21 is respectively embedded in the corresponding chute 31.

[0061] In practical applications, the cross-sectional shape of the slider 21 can be rectangular, trapezoidal, semi-circular, etc. The cross-sectional shape of the chute 31 just needs to match the cross-sectional shape of the slider 21. This embodiment does not make specific limitations on this.

[0062] In addition, in the embodiment of the present application, a friction-increasing layer is respectively provided in each chute 31, so that each slider 21 is in interference fit with the corresponding chute 31, which is used to limit the sliding speed of the collection basket 20 full of vegetables.

[0063] In practical applications, when the collection basket 20 filled with vegetables slides down vertically, due to gravity, the sliding speed is too fast, and some vegetables may fall out of the basket onto the ground or be damaged when landing, affecting the harvesting quality and weight of the vegetables. Based on this, in the embodiments of the present application, a friction-increasing layer can be provided in each chute 31 to increase the friction force, thereby restricting the sliding speed of the collection basket 20 filled with vegetables.

[0064] In addition, in some embodiments, the friction-increasing layer can be one of a rubber layer, a silicone layer, a polyurethane layer, a leather layer, and a nylon layer. The present application does not make specific limitations on which one to specifically select. In this embodiment, the friction-increasing layer can be fixed on each surface in the chute 31 by bonding (such as with adhesives, laser bonding, etc.), fasteners (such as screws, bolts, etc.), or the friction-increasing layer can be fixed on the bottom surface or all side surfaces in the chute 31.

[0065] In other embodiments, each chute 31 is respectively provided with a friction-increasing structure, and the friction-increasing structure can be one of a knurled structure, a texture structure, and a structure composed of a plurality of bumps. The friction-increasing structure can be provided on each surface in the chute 31, or can be provided on the bottom surface or all side surfaces of the chute 31.

[0066] In addition, in other embodiments, the sliding member can be a round wheel, and the sliding part can be a slide rail; when the two placement plates 30 are in a closed state, along the vertical direction, the round wheels are respectively aligned with the corresponding slide rails; when the two placement plates 30 are in an open state, each round wheel is respectively embedded in the corresponding slide rail.

[0067] In addition, in the embodiments of the present application, the collection device further includes a speed-limiting component (not shown in the figure); the speed-limiting component is installed on the bracket 10 and is located on the side of the collection basket 20 away from the ground. The speed-limiting component is used to tighten the collection basket 20 along the first direction during the sliding process of the collection basket 20 filled with vegetables, so as to restrict the sliding speed of the collection basket 20, where the first direction is the direction opposite to the sliding direction of the collection basket 20.

[0068] As Figure 1 and as Figure 2 shown, the bracket 10 of the collection device includes a frame formed by surrounding four flat plates 12 and a "U-shaped" pull rod 11 fixed on the frame. The opening of the "U-shaped" pull rod 11 faces the frame. The "U-shaped" pull rod includes a cross bar 111 and two vertical bars 112. The vertical bars 112 are arranged in the vertical direction, and the cross bar 111 is perpendicular to the vertical bars 112. The "U-shaped" pull rod 11 and the frame can be an integrally formed structure, or the "U-shaped" pull rod can be fixed to the frame by fasteners, welding, bonding, etc.

[0069] In the embodiments of the present application, the speed-limiting component is installed on the cross bar 111 of the "U-shaped" pull rod 11. When the collection basket 20 full of vegetables slides downwards, the staff or the power component tightens the collection basket 20, applying an upward pulling force to the collection basket 20. This pulling force can offset a part of the gravity to limit the sliding speed of the collection basket 20. It should be noted that the first direction refers to the direction in which the collection basket 20 is pulled when the staff or the power component tightens the collection basket 20, and this direction is opposite to the sliding direction of the collection basket 20. The present application provides a structure for limiting the sliding speed of the collection basket 20 full of vegetables, avoiding damage or dropping of some vegetables due to the too-fast sliding speed of the collection basket 20 full of vegetables.

[0070] In some embodiments, the speed-limiting component includes: a traction rope and a pulley; the pulley is installed on the bracket 10, and the pulley tightens the collection basket 20 through the traction rope. When the collection basket 20 full of vegetables slides down, the pulley tightens the collection basket 20 in the first direction to prevent the collection basket 20 from sliding downwards.

[0071] It should be noted that this pulley is a simple machine used to lift heavy objects and save effort. The pulley in this embodiment can be one of a movable pulley, a fixed pulley or a pulley block. The structure of the pulley is a technology well-known to those skilled in the art and will not be elaborated here. Taking the fixed pulley as an example, the wheel body of the fixed pulley is fixed on the cross bar 111. One end of the traction rope sleeved on the groove of the wheel body is connected to the collection basket 20, and the other end is a free end for the staff to pull the traction rope, thereby tightening the collection basket 20 to move upwards or have a tendency to move upwards. To save labor costs, the free end of the traction rope can be driven by a power component. The power component includes a motor and a rotating shaft fixedly installed on the frame of the bracket 10. The output shaft of the motor is connected to the rotating shaft through a coupling, and the free end of the traction rope is wound around the rotating shaft. In actual work, the rotation of the motor can drive the rotation of the rotating shaft to drive the traction rope to move around the wheel body, thereby driving the collection basket 20 full of vegetables to move upwards to prevent the collection basket 20 from sliding downwards, playing a role in limiting the sliding speed of the collection basket 20.

[0072] In addition, in some embodiments, such as Figure 1 and Figure 2As shown in the figure, through slots 22 are respectively provided on two opposite flat plates 12 of the collection basket 20. The two through slots 22 are for the traction ropes in the speed-limiting assembly to pass through, so as to connect the bracket 10 and the collection basket 20. In this way, during the process of the collection basket 20 full of vegetables sliding down, the traction rope pulls up the collection basket 20 tightly to prevent the collection basket 20 from sliding down. In addition, the through slots 22 also facilitate the staff to carry the collection basket 20. In some other embodiments, the through slots 22 can be replaced by handles, and the handles are fixed to the outer surfaces of the two opposite flat plates 12 of the collection basket 20 by means of fasteners, welding, etc. It should be noted that the two opposite flat plates 12 are not the two flat plates 12 on the first side and the second side of the collection basket 20.

[0073] In addition, in the embodiment of the present application, as Figure 3 shown, the collection device further includes: a control module 60 and an alarm 50 installed on the bracket 10; the control module 60 is electrically connected to the alarm 50, and the control module 60 is configured to, when the collection basket 20 is full of vegetables, control the alarm 50 to give an alarm.

[0074] Specifically, the control module 60 can be installed on the frame of the bracket 10, and the alarm 50 can be installed on the frame of the bracket 10 or on one of the vertical rods 112 of the "U-shaped" pull rod 11. The alarm 50 can be a buzzer or an audible and visual alarm. When the collection basket 20 is full of vegetables, the control module 60 controls the buzzer to send an alarm signal to prompt the staff, so as to facilitate the staff to timely place the empty collection basket 20 on the placement plate 30 for continuing to collect vegetables. In practical applications, there is another situation. After the staff hears the alarm signal, they may not be able to timely place the empty collection basket 20 on the placement plate 30. In this case, the control module 60 can control the harvester to pause harvesting until the staff places the empty collection basket 20 on the placement plate 30, and then the control module 60 controls the harvester to continue harvesting.

[0075] In addition, in the embodiment of the present application, the collection device further includes: a pressure sensor 40; the pressure sensor 40 is installed inside one of the two placement plates 30, the pressure sensor 40 is electrically connected to the control module 60, and the pressure sensor 40 is configured to judge the weight of the collection basket 20 for collecting vegetables and send the weight judgment result to the control module 60; the control module 60 is specifically configured to, if the received weight judgment result reaches a preset threshold, control the alarm 50 to give an alarm.

[0076] Specifically, in order to improve the stability of the placement of the pressure sensor 40, a receiving cavity matching the structure of the pressure sensor 40 can be opened in a placement plate 30, and the pressure sensor 40 is fixedly installed in the receiving cavity. In practical applications, the pressure sensor 40 judges the weight of the collection basket 20 for collecting vegetables in real time and sends the weight judgment result to the control module 60; the control module 60 compares the received weight judgment result with a preset threshold value. If it reaches the preset threshold value, the control alarm 50 alarms. Among them, the threshold value is set according to the specific weight of a basket of vegetables.

[0077] For another situation in practical applications, the control module 60 compares the received weight judgment result with a preset threshold value. If it reaches the first preset threshold value, the control alarm 50 alarms and sends a stop harvesting signal to control the harvester to pause harvesting. When the received weight judgment result reaches the second preset threshold value, it means that the staff has placed the empty collection basket 20 on the placement plate 30, and the control module 60 controls the harvester to continue harvesting after a preset time.

[0078] In addition, in the embodiment of the present application, the collection device further includes: a camera 70; the camera 70 is installed on the bracket 10 and is located on the side of the collection basket 20 away from the ground. The camera 70 is electrically connected to the control module 60. The camera 70 is used to take pictures of the collection basket 20 and send the taken pictures to the control module 60; specifically, the control module 60, if the received picture matches the pre-stored picture, controls the alarm 50 to alarm.

[0079] Such as Figure 1 and Figure 2 As shown, the camera 70 is installed on the cross bar 111 of the bracket 10. In practical applications, the camera 70 takes pictures of the collection basket 20 in real time and sends the taken pictures to the control module 60; the control module 60 compares the received pictures with the pre-stored pictures. If they match, the control alarm 50 alarms. Among them, the pre-stored pictures are pictures of the collection basket filled with vegetables, and generally pictures of the harvester harvesting all types of vegetables are pre-stored.

[0080] For another situation in practical applications, the control module 60 compares the received pictures with the pre-stored pictures. If they match, the control alarm 50 alarms and sends a stop harvesting signal to control the harvester to pause harvesting. When the received pictures match the pictures of the empty collection basket 20, the control module 60 controls the harvester to continue harvesting after a preset time.

[0081] It should be noted that the preset time in the embodiment of the present application can be 3 seconds, 5 seconds, etc. The specific set time can be analyzed according to the specific situation, mainly to ensure that after the staff places the empty collection basket 20, they have walked into the safe area, which can avoid the safety hazards brought by the harvesting harvester to the staff.

[0082] In summary, by integrating artificial intelligence technology, the collection device of the present application can automatically identify the state where the collection basket 20 is full of vegetables, improving the intelligence level of the collection device.

[0083] In addition, in the embodiments of the present application, each placement plate 30 is respectively rotatably connected to the bracket 10 through a rotating mechanism 80; as Figures 4 to 7 shown, a structural diagram of the placement plate and the bracket connected by two rotating mechanisms is shown.

[0084] For the first rotating mechanism, as Figure 4 、 Figure 5 shown, the first rotating mechanism includes a first connecting plate 81, a second connecting plate 82, a first connecting rod 83, a second connecting rod 84 and an elastic member 85. Each first connecting plate 81 is fixedly connected to the corresponding placement plate 30, and each second connecting plate 82 is fixedly connected to the bracket 10; one end of the first connecting rod 83 is rotatably connected to the first connecting plate 81, and the other end is rotatably connected to the second connecting plate 82. One end of the second connecting rod 84 is rotatably connected to the first connecting plate 81, and the other end is rotatably connected to the second connecting plate 82. One end of the elastic member 85 is connected to the first connecting plate 81, and the other end is connected to the second connecting plate 82.

[0085] Specifically, the rotating mechanism between one placement plate 30 and the bracket 10 is taken as an example for illustration below. As Figure 5 shown, when the placement plate 30 is in a horizontal state, the first connecting plate 81 is fixedly installed on the bottom surface of the placement plate 30 through a fastener, and the second connecting plate 82 is fixedly installed on the inner surface of a flat plate 12 of the bracket 10 frame through a fastener. Among them, with reference to the traveling direction of the harvester (i.e., the front), this flat plate 12 is the flat plate 12 on the front side of the bracket 10 frame. One end of the first connecting rod 83 is rotatably connected to the first connecting plate 81 through a pin hinge, and the other end is rotatably connected to the second connecting plate 82 through a pin hinge. One end of the second connecting rod 84 is rotatably connected to the first connecting plate 81 through a pin hinge, and the other end is rotatably connected to the second connecting plate 82 through a pin hinge, so that the first connecting plate 81 can rotate 90° relative to the second connecting plate 82, thereby driving the placement plate 30 to rotate 90° relative to the bracket 10. In this way, the placement plate 30 can be switched between a horizontal state and a vertical state. Among them, the lengths of the first connecting rod 83 and the second connecting rod 84 are different. As Figure 4 shown, the first connecting rod 83 and the second connecting rod 84 are arranged at intervals, and the length of the first connecting rod 83 is longer than the length of the second connecting rod 84.

[0086] Specifically, the elastic member is preferably a spring, which has low cost and is easy to install. Of course, the elastic member can also be a corrugated rubber tube, which can be specifically selected according to actual needs. The elastic member in the following is described by taking a spring as an example.

[0087] As Figure 4 and Figure 5 shown, a first connecting column 811 is provided on the first connecting plate 81, a second connecting column 821 is provided on the second connecting plate 82, a first groove is provided on the outer circumferential surface of the first connecting column 811, a second groove is provided on the outer circumferential surface of the second connecting column 821, one end of the spring is sleeved in the first groove, and the other end of the spring is sleeved in the second groove. When the placing plate 30 is in a horizontal state, as Figure 4 shown, the first type of rotating mechanism is folded together. Due to the dead point existing in the rotating mechanism, the spring is in a stretched state and is stuck and immovable. Therefore, the rotating mechanism will not bounce up to ensure that the placing plate 30 always remains in a horizontal state; under the action of an external force, the placing plate 30 rotates relative to the bracket 10. When the placing plate 30 rotates to a vertical state, the spring contracts and has a pulling force, which plays a positioning role to make the placing plate 30 always remain in a vertical state.

[0088] It should be noted that in order to make the placing plate 30 rotate more smoothly and improve the bearing capacity of the placing plate 30 for placing the collection basket 20, the placing plate 30 and the bracket 10 can be rotatably connected through two first types of rotating mechanisms. Referring to Figure 1 、 Figure 2 、As Figure 4 and Figure 5 , along the front-back direction, the placing plate 30 is rotatably connected to the flat plate 12 on the front side of the bracket 10 frame through one rotating mechanism and is rotatably connected to the flat plate 12 on the rear side of the bracket 10 frame through another rotating mechanism.

[0089] For the second type of rotating mechanism, as Figure 6 and Figure 7As shown in the figure, it includes: a third connecting rod 86, a roller 87, a tension spring 88, and a sliding plate 89. The third connecting rod 86 includes a first connecting portion 861, a second connecting portion 862, and a third connecting portion 863. The first connecting portion 861 is connected to the third connecting portion 863 through the second connecting portion 862. There is a first preset angle between the first connecting portion 861 and the second connecting portion 862, and a second preset angle between the second connecting portion 862 and the third connecting portion 863. The first preset angle and the second preset angle are both obtuse angles. When the placement plate 30 is in a horizontal state, one end of the first connecting portion 861 and the roller 87 are respectively hinged to the bottom surface of the placement plate 30 and are arranged at intervals. The first connecting portion 861 and the second connecting portion 862 are fixedly connected through a cylindrical barrel. The rotating mechanism further includes a first mounting rod 801, a second mounting rod 802, and a third mounting rod 803. Along the vertical direction, the first mounting rod 801 and the second mounting rod 802 are arranged at intervals on the inner surface of the front flat plate 12 in the frame of the bracket 10. Among them, the first mounting rod 801 is far from the ground. The cylindrical barrel is sleeved on the first mounting rod 801 and has a clearance fit. The third mounting rod 803 is arranged at the connection of the second connecting portion 862 and the third connecting portion 863. The third mounting rod 803 is located between the first mounting rod 801 and the second mounting rod 802. One end of the tension spring 88 is fixed to the second mounting rod 802, and the other end is fixed to the third mounting rod 803. The sliding plate 89 is fixed to the inner surface of the bracket 10 and is located on the side of the roller 87 away from the placement plate 30, for supporting the roller 87 and enabling the roller 87 to roll on it. During operation, the pulling force of the tension spring 88 positions the rotating mechanism. As Figure 6 shown, when the placement plate 30 is in a horizontal state, under the action of an external force, the third connecting rod 86 is rotated. The third connecting rod 86 rotates, and its roller 87 rolls along the sliding plate 89, causing the placement plate 30 to rotate to a vertical state. The tension spring 88 is only stretched during the rotation of the third connecting rod 86. When the placement plate 30 is in a horizontal and vertical state, the tension spring 88 is approximately in its original state and plays a positioning role to keep the placement plate 30 in its current state.

[0090] As Figure 6 and Figure 7 shown, the sliding plate 89 is composed of a first sliding portion 891, a second sliding portion 892, and a third sliding portion 893 connected in sequence. The third sliding portion 893 is close to the ground. The first sliding portion 891 is arranged in the horizontal direction, the third sliding portion 893 is arranged in the vertical direction, the second sliding portion 892 is an inclined plate. The angle between the first sliding portion 891 and the second sliding portion 892 is an obtuse angle, and the angle between the second sliding portion 892 and the third sliding portion 893 is an obtuse angle.

[0091] As Figure 6 and Figure 7As shown in the figure, when the placement plate 30 is in a horizontal state, two mounting brackets 90 are spaced and installed on the bottom plane of the placement plate 30. One end of the first connecting portion 861 is rotatably connected to one mounting bracket 90 through a pin hinge, and the roller 87 is rotatably connected to the other mounting bracket 90 through a pin hinge. Along the traveling direction of the cutting machine, the mounting bracket 90 is composed of two symmetrical mounting plates 901. The cross-sectional shape of the mounting plate 901 is: surrounded by a quadrilateral and a semicircle, similar to the cross-sectional shape of a lug.

[0092] In addition, in the embodiment of the present application, a baffle is provided on the bracket 10. The baffle is arranged along the periphery of the collection basket 20 to prevent the collection basket 20 from slipping due to the harvester traveling too fast or vibrating greatly during traveling.

[0093] It should be noted that the fasteners used in the present application can be selected from one of bolts, screws and welding nails, and can be specifically selected according to actual needs. This embodiment does not limit this.

[0094] In summary, in the embodiment of the present application, it has at least the following advantages:

[0095] (1) When the two placement plates are in an open state, since the sliding members on the collection basket are slidably engaged with the sliding portions on the placement plates, the collection basket full of vegetables can slide down to the ground, avoiding manual handling, saving labor costs, improving handling efficiency, and being able to avoid the problem of being injured due to improper operation when manually approaching the operating harvester to handle the collection basket.

[0096] (2) Since the present application is provided with a speed limiting component, when the collection basket full of vegetables slides down, the speed limiting component pulls the collection basket upward to limit the sliding speed of the collection basket, avoiding some vegetables from being damaged or falling due to the too fast sliding speed of the collection basket full of vegetables.

[0097] (3) The present application integrates artificial intelligence technology, enabling the collection device to automatically identify the state of the collection basket 20 being full of vegetables, improving the intelligent level of the collection device.
