Description
Technical Field
[0001] This invention relates to the field of tomato processing and tomato harvesting, specifically to a method and apparatus for harvesting tomatoes without stopping the machine while cleaning the screen of a tomato color sorter. Background Technology
[0002] During the mechanical harvesting of tomatoes, soil clods and unripe fruit are easily harvested into the machine. This requires a color sorter to remove these parts. The glass screen of the color sorter is easily obscured by a mixture of splashed tomato juice and dust, which seriously affects the sorter's identification function. The glass screen needs to be cleaned in a timely manner. However, since the time the glass screen is covered is highly dependent on the environment and the condition of the tomatoes, the cleaning time cannot be fixed. Constantly stopping the machine for cleaning not only affects operational efficiency but also increases the harvest loss rate. Summary of the Invention
[0003] To address the issue that stopping the color sorter's glass screen for cleaning affects harvesting efficiency, this invention provides a method and corresponding apparatus for harvesting tomatoes without stopping the machine while cleaning the color sorter's screen. A temporary tomato storage device is added to the tomato conveyor chain, allowing harvested tomatoes to enter the temporary storage device, temporarily interrupting the original tomato conveyor chain and automatically creating a working gap for the color sorter. After cleaning the color sorter during this working gap, the tomatoes in the temporary storage device are returned to the tomato conveyor chain. Throughout the entire process, tomato harvesting can continue without stopping the machine and without affecting the operation of the color sorter.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a harvesting device that does not stop the machine while cleaning the screen of a tomato color sorter, comprising a suspension device, a storage device, a fruit unloading device, and a power control system. The suspension device is located above the storage device, the fruit unloading device is located at the bottom rear of the storage device, and the power control system is an electromagnetic control circuit powered by an onboard hydraulic tank and an onboard power supply, providing power to the device.
[0005] The suspension device consists of two sets, symmetrically distributed on both sides of the storage device. Each suspension device comprises a suspension rod one, a suspension rod two, a support sleeve one, a support sleeve two, and a hydraulic cylinder one. One end of each suspension rod one and suspension rod two is welded to support sleeve one. Support sleeve one is hinged to a support base fixed to the tomato harvester at one end via a pin shaft one. Pin shaft one has a pin hole at its outer end. When support sleeve one is hinged to pin shaft one, a cotter pin is installed in the pin hole to prevent support sleeve one from detaching from pin shaft one. One end of the hydraulic cylinder one is hinged to pin shaft two, which is also fixed to the tomato harvester at one end. Pin shaft two has a pin hole at its outer end. When the cylinder body is hinged to pin shaft two, a cotter pin is installed in the pin hole to prevent the cylinder body from detaching from pin shaft two. One end of the push rod of hydraulic cylinder 1 has a round hole, which is hinged to two lifting lugs with round holes welded to suspension rod 1 via pin 3. The outer end of pin 3 has a pin hole, and a cotter pin is installed in the pin hole to prevent the push rod of hydraulic cylinder 1 from detaching from the lifting lug. The other ends of suspension rod 1 and suspension rod 2 are each welded with a support sleeve 2. The two support sleeves 2 are respectively hinged to two pins 4 that are fixed at one end to the same outer reinforcing plate of the storage device (the two support sleeves 2 and the storage device can also be fixedly connected). The outer end of pin 4 has a pin hole. When support sleeve 2 is hinged to pin 4, a cotter pin is installed in the pin hole to prevent support sleeve 2 from detaching from pin 4.
[0006] The storage device is welded together from two symmetrical side plates, a bottom plate, a bottom plate, a U-shaped support plate, and a U-shaped support plate. Reinforcing plates are welded to the inner and outer sides of both side plates. Two through holes are opened on the reinforcing plates and the corresponding side plates, each with a four-pin welded to it. The two ends of the U-shaped support plate are welded to the front ends of the two reinforcing plates, supporting the bottom plate. The lower rear edges of both side plates are bent inwards at right angles. The lower side of the bottom plate is welded to the upper side of the bottom plate. The lower side of the bottom plate and the two side plates form a downward-facing rectangular unloading port. The two ends of the U-shaped support plate are welded to the rear ends of the two reinforcing plates, supporting the right-angled bends of the two side plates.
[0007] The unloading device includes a bending plate, a shaft, and two hydraulic cylinders for controlling the opening and closing of valves. One end of the cylinder body of the two cylinders is connected to a reinforcing plate on the outside of the storage device. One end of the pull rod of the two cylinders is installed on the lower side of the short plate at the front end of the bending plate. A steel pipe is welded to the outside of the bending point of the bending plate. The shaft passes through the steel pipe, and both ends of the shaft are hinged to the lower ends of the two side plates. The upper end of the side plates is welded to the reinforcing plate. The long plate at the rear end of the bending plate rests on the right-angle bend of the lower rear end of the two side plates of the storage device and fits against the right-angle bend. Eight evenly distributed reinforcing ribs are welded to the bottom side of the short plate of the bending plate.
[0008] The power control system includes a main switch, a time control switch one, an electromagnetic hydraulic directional control valve one controlling hydraulic cylinder one, an electromagnetic hydraulic directional control valve two controlling the opening and closing of the control cylinder, a time control switch two, a delay switch, and electronic and hydraulic components required to maintain the stability of the hydraulic control system. Electromagnetic hydraulic directional control valve one and electromagnetic hydraulic directional control valve two are connected in parallel. The time control switch delays the directional switching of the electromagnetic hydraulic directional control valves by using an electronic timer and switching the energization of the left and right coils of the electromagnetic hydraulic directional control valves. The electromagnetic hydraulic directional control valves control the operation of the hydraulic cylinders. The entire control circuit is controlled by the main switch. The times of the delay switch and the time control switch are set according to the completion time on the screen of the tomato color sorter.
[0009] The beneficial effects of this invention are:
[0010] 1. This invention allows the tomato harvester to automatically create time gaps for tomato color sorting without stopping, thus completing the cleaning operation of the color sorter screen. This ensures the color sorting effect without affecting the harvesting efficiency of processed tomatoes.
[0011] 2. The suspension device in this invention has a simple structure and a single power source. It can be started with one button in the cab by using a delay control device and a hydraulic solenoid valve, which is convenient to operate. It can be combined with an identification system and a cleaning device to form a color sorting device adaptive cleaning system, which enhances the intelligence of the tomato harvester.
[0012] 3. The storage device in this invention is designed according to the transportation law of processed tomatoes. It has a simple and reliable structure, small working space, and is easy to configure as a whole machine. It is also equipped with lifting lugs to increase the fixed constraint and enhance transportation safety.
[0013] 4. The unloading device in this invention is designed according to the storage distribution pattern of tomatoes. It utilizes the gravity distribution pattern of tomatoes to reduce the power required. During unloading, it automatically forms an isolation plate to prevent new processed tomatoes from entering the storage device. In addition, the opening and closing degree of the tomato unloading port is controlled by the controllable extension and retraction speed of the hydraulic cylinder to ensure the normal operation of tomato color sorting.

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] See attached document Figure 1 This invention provides a harvesting device that allows for non-stop harvesting while cleaning the screen of a tomato color sorter. A temporary storage device is installed on the tomato conveyor chain, comprising a suspension device, a storage device, and a fruit unloading device. The suspension devices are symmetrically distributed on both sides above the storage device, and the fruit unloading device is located below and behind the storage device. The entire non-stop harvesting device is located on the conveyor belt in front of the tomato harvester's color sorter (corresponding to the appendix of this invention). Figure 1 The belt conveyor device 2 (5) is directly above it.
[0023] The suspension device (1) has two sets, which are located on both sides of the storage device and are symmetrically distributed. Each set consists of a suspension rod one (1-1), a suspension rod two (1-10), a support sleeve one (1-8), a support sleeve two (1-12), and a hydraulic cylinder one (1-4). One end of the suspension rod one (1-1) and the suspension rod two (1-10) are welded to the support sleeve one (1-8). The support sleeve one (1-8) and the support seat (1-11) fixed at one end on the tomato harvester are hinged by a pin shaft one (1-9). The outer end of the pin shaft one (1-9) has a pin hole. When the support sleeve one (1-8) and the pin shaft one (1-9) are hinged, a cotter pin is installed in the pin hole to prevent the support sleeve one (1-8) from detaching from the pin shaft one (1-9). One end of the hydraulic cylinder (1-4) is hinged to a lifting lug (1-7) fixed to the tomato harvester at one end via a pin (1-6). The outer end of pin (1-6) has a pin hole. When the cylinder body is hinged to pin (1-6), a cotter pin is installed in the pin hole to prevent the cylinder body from detaching from pin (1-6). One end of the push rod of hydraulic cylinder (1-4) has a round hole, which is hinged to two cylinder lifting lugs (1-2) with round holes welded to suspension rod (1-1) via a pin (1-3). The outer end of pin (1-3) has a pin hole, and a cotter pin is installed in the pin hole to prevent the push rod of hydraulic cylinder (1-4) from detaching from the cylinder lifting lug (1-2). The other ends of suspension rod (1-1) and suspension rod (1-10) are each welded with… A second support sleeve (1-12) is attached. The two second support sleeves (1-12) are respectively hinged to two pins (2-10) that are fixed at one end to the same outer reinforcing plate (2-4) of the storage device (2). The outer end of the pins (2-10) has a pin hole. When the second support sleeve (1-12) is hinged to the pins (2-10), a cotter pin is installed in the pin hole to prevent the second support sleeve (1-12) from detaching from the pins (2-10). In addition, a fixed half ring (1-5) is welded to the first suspension rod (1-1). When the tomato harvester is in the transport state, the first hydraulic cylinder (1-4) retracts the cylinder rod, driving the device to rotate clockwise. When it rotates about 90°, the fixed half ring (1-5) is connected to the hook (1-13) fixed on the tomato harvester, so that the entire device is suspended. The suspension effect is shown in the attached figure. Figure 3 As shown.
[0024] Combined with appendix Figure 1 and attached Figure 2As shown, the storage device (2) consists of two symmetrical side plates (2-1), a bottom plate (2-2), a bottom plate (2-3), four reinforcing plates (2-4), a U-shaped support plate (2-5), a hydraulic cylinder connecting pin (2-6), an opening and closing control cylinder (2-7), two side plates (2-8), a U-shaped support plate (2-9), and a fourth pin (2-10). Reinforcing plates (2-4) are welded to the inner and outer sides of both side plates (2-1). Two through holes are opened on each side of the two reinforcing plates (2-4) and the corresponding side plate (2-1), and both are welded with... Pin 4 (2-10) and U-shaped support plate 1 (2-5) are welded to the front ends of the two outer reinforcing plates 1 (2-4) respectively, supporting the bottom plate 2 (2-3). The lower side of the rear end of the two side plates 1 (2-1) is bent inward at a right angle. The lower side of the bottom plate 1 (2-2) is welded to the upper side of the bottom plate 2 (2-3). The lower side of the bottom plate 2 (2-3) and the two side plates 1 (2-1) form a rectangular fruit unloading port with the opening facing downward. U-shaped support plate 2 (2-9) is welded to the rear ends of the two reinforcing plates 1 (2-4) respectively, supporting the right angle bends of the two side plates 1 (2-1). One end of the cylinder body of the opening and closing control cylinder (2-7) is hinged to the opening and closing cylinder hook pin (2-6) welded on the first reinforcing plate (2-4). The outer end of the opening and closing cylinder hook pin (2-6) has a pin hole. When the cylinder body of the opening and closing control cylinder (2-7) and the opening and closing cylinder hook pin (2-6) are hinged, a cotter pin is installed in the pin hole to prevent the cylinder body of the opening and closing control cylinder (2-7) from detaching from the opening and closing cylinder hook pin (2-6). The upper end of the second side plate (2-8) is welded and fixed to the first reinforcing plate (2-4), and the lower end has a hole.
[0025] like Figure 4 and Figure 5As shown, the unloading device (3) includes four support plates (3-1), two pins (3-2), one bending plate (3-3), eight reinforcing ribs (3-4), three reinforcing side plates (3-5), a shaft (3-6), a steel pipe (3-7), and two reinforcing side plates (3-8). The three reinforcing side plates (3-5) are evenly distributed at three positions: inside, outside, and in the middle of the two parallel reinforcing side plates (3-8), forming the basic frame of the unloading device. Two support plates (3-1) are welded to the front ends of the inner and outer reinforcing side plates (3-5). One end of the opening and closing control cylinder (2-7) pull rod is hinged to the pin (3-2) welded to the two support plates (3-1) on one side. The outer end of the pin (3-2) has a pin hole. The opening and closing control cylinder (2-7) pull rod and the pin (3-2) are connected. When hinged, a cotter pin is installed in the pin hole to prevent the opening and closing control cylinder (2-7) pull rod from disengaging from the pin shaft five (3-2). All three reinforcing side plates one (3-5) have semi-circular bends, and the bends are tangent to the steel pipe (3-7). The bending plate (3-3) is located above the reinforcing side plate one (3-5), and its outer side of the bend is welded to the steel pipe (3-7). All three reinforcing side plates one (3-5) are welded to the bending plate (3-3). Eight reinforcing ribs (3-4) are welded to the outer side of the short side at the front end of the bending plate (3-3). The left end of the reinforcing rib (3-4) is fixed to the left vertical reinforcing side plate two (3-8), and the right end is fixed to the steel pipe (3-7). The shaft (3-6) passes through the inside of the steel pipe (3-7), and the two ends of the shaft (3-6) are connected to the holes opened at the lower ends of the two side plates two (2-8).
[0026] like Figure 6 As shown, the power control system includes a power battery, a main switch, a time control switch one, an electromagnetic hydraulic directional control valve one, a time control switch two, and an electromagnetic hydraulic directional control valve two. The main switch is located on the main circuit and is used to control the start and stop of the entire power control system. The time control switch one is located on the first branch and is used to control the electromagnetic hydraulic directional control valve one. The time control switch two and the delay switch are connected in series and located on the second branch. The time control switch two is used to control the electromagnetic hydraulic directional control valve two.
[0027] The harvesting device of this invention has a symmetrical structure, that is, the hanging device, the storage device and the unloading device can all be symmetrical structures.
[0028] The process of using this invention is as follows:
[0029] During tomato harvesting, the fixed half-ring (1-5) on the suspension rod (1-1) is detached from the hook (1-13). When the color sorting device screen needs cleaning, the main switch is closed, the control circuit is powered on, and the delay switch is in the off state. The time control switch controls the electromagnetic hydraulic reversing valve to drive the hydraulic cylinder (1-4) to start working. The rod of the hydraulic cylinder (1-4) extends until the upper surface of the storage device is parallel and aligned with the upper surface of the belt transmission device (4) (the effect is as follows). Figure 1 As shown), at this time, the storage device begins to intercept the processed tomatoes conveyed by the belt conveyor device one (4). After the screen cleaning work is completed, the delay switch begins to close according to the preset time. At this time, the time control switch two controls the electromagnetic hydraulic reversing valve two to drive the opening and closing control cylinder (2-7) to start working. The pull rod of the opening and closing control cylinder (2-7) extends to the predetermined position, and the tomatoes in the storage device fall from the bottom rectangular unloading port and fall into the tomato conveyor belt two (corresponding to the short side of the front end of the unloading device bending plate) along the short side of the unloading device bending plate. Figure 1 On the belt conveyor device (II), subsequent color sorting is carried out. At the same time, the long side of the rear end of the bending plate begins to retract towards the inside of the storage device, and a baffle is formed on the outside of the long side of the bending plate to prevent the processed tomatoes from entering the storage device. The processed tomatoes resume normal transmission, and the time control switch one automatically switches the connection point with the electromagnetic hydraulic reversing valve one, controlling the electromagnetic hydraulic reversing valve one to drive the hydraulic cylinder one to retract the hydraulic rod. After the processed tomatoes are unloaded from the storage device, the entire device begins to return to the initial position. At this time, the time control switch two automatically switches the connection point with the electromagnetic hydraulic reversing valve two, controlling the electromagnetic hydraulic reversing valve two to drive the opening and closing control cylinder to retract the hydraulic rod. The opening and closing control cylinder retracts the hydraulic rod, and the entire working process ends.
[0030] It should be noted that the directional terms such as up, down, left, right, top, bottom, inside, outside, horizontal, vertical, and inclined used in this invention are merely for the convenience of clearly describing the device structure and are not intended to limit the device construction.

At this time, the storage device (2) begins to intercept the processed tomatoes transported by the conveyor belt (4). After the color sorter screen cleaning is completed, the delay switch closes according to the preset time. At this time, the second time control switch controls the second electromagnetic hydraulic reversing valve to drive the opening and closing control cylinder (2-7) to start working. The pull rod of the opening and closing control cylinder (2-7) extends to the predetermined position. The tomatoes in the storage device fall from the bottom rectangular unloading port and fall along the short side of the front end of the unloading device bending plate onto the belt conveyor device (5) for subsequent color sorting. At the same time, the long side of the rear end of the bending plate begins to retract towards the inside of the storage device. A baffle is formed on the outside of the long side of the bending plate to prevent the processed tomatoes from entering the storage device. The processed tomatoes resume normal transmission. The first time control switch switches the connection point with the first electromagnetic hydraulic reversing valve and controls the first electromagnetic hydraulic reversing valve to drive the first hydraulic cylinder (1-4) to start retracting the hydraulic pull rod. The entire device returns to the initial suspended position. At this time, the second time control switch automatically switches the connection point with the second electromagnetic hydraulic reversing valve and controls the second electromagnetic hydraulic reversing valve to drive the opening and closing control cylinder (2-7) to retract the hydraulic pull rod. The entire working process ends.
