Description

Technical Field

[0001] The utility model relates to the field of lettuce harvesting devices, and particularly relates to a continuous vegetable harvester with a function of removing leaves and stems. Background Technique

[0002] As a widely consumed leafy vegetable, the harvesting and primary processing of lettuce have an important impact on the efficiency and cost of the entire supply chain. Traditionally, the harvesting of lettuce and the separation of leaves and stems are two independent processes. First, the whole lettuce plants are pulled out or cut from the soil by using harvesting machinery or manually, and then the leaves and stems are separated in the field or processing workshop. This process often relies on manual operation or inefficient semi-automatic equipment. This method is not only labor-intensive and inefficient, but also difficult to achieve continuous high output in large-scale agricultural production.

[0003] More critically, the lettuce leaves that are not separated in time during the harvesting process may be wound around the components of the harvesting machinery, causing jams or damage, forcing frequent shutdowns for cleaning, and seriously slowing down the harvesting progress. Especially in a humid or rainy environment, the adhesiveness of the leaves is enhanced, and the problem is more prominent, greatly affecting the reliability and economy of mechanized harvesting.

[0004] Therefore, developing a continuous vegetable harvester that can integrate the functions of harvesting and separating leaves and stems is of great significance for improving the harvesting efficiency of leafy vegetables such as lettuce, reducing labor requirements, and lowering production costs. Content of the Utility Model

[0005] The purpose of the utility model is to provide a continuous vegetable harvester with a function of removing leaves and stems to solve the problems of low efficiency and difficulty in achieving continuous high output during the harvesting of lettuce as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A continuous vegetable harvester with a function of removing leaves and stems includes a frame, a leaf-removing and harvesting mechanism, and a conveying mechanism; a first working station and a second working station are arranged on the frame; the leaf-removing and harvesting mechanism is arranged at the first working station, the leaf-removing and harvesting mechanism has a leaf-removing component and a cutting component, a receiving area is arranged between the leaf-removing component and the cutting component, and the receiving area is suitable for cutting materials; the conveying mechanism is arranged at the second working station, the conveying mechanism has a conveying channel, and the conveying channel is communicated with the receiving area and is suitable for conveying materials; wherein, in the state of the frame moving forward, along the direction away from the moving direction of the frame, materials enter the receiving area through the leaf-removing component, are cut by the cutting component, and are conveyed by the conveying channel.

[0008] Further, the defoliation component has a groove plate, a rotating rod and a fixed rod which are vertically arranged on the first station. The rotating rod and the fixed rod respectively penetrate through both sides of the groove plate. The rotating rod is in threaded fit with the groove plate, and the fixed rod is in slidable fit with the groove plate.

[0009] Further, the cutting component has a cutting disc which is rotatably arranged on the second station. The groove plate has an anti - toppling side which is arranged on the side close to the cutting disc, and the anti - toppling side is parallel to the axial direction of the cutting disc.

[0010] Further, the conveying mechanism has two groups of conveyor belt components. Along the extending direction of the conveying channel, the two groups of conveyor belt components are respectively arranged on both sides of the conveying channel, and at least a part of the sides of the two groups of conveyor belt components close to the receiving area can extend into the receiving area.

[0011] Further, the conveyor belt component has a plurality of synchronous pulleys and a synchronous belt. The plurality of synchronous pulleys are all arranged at intervals towards the conveying channel, and the plurality of synchronous pulleys are all in contact with and meshed with the synchronous belt for driving connection.

[0012] Further, the conveyor belt component has a plurality of connecting shafts. The plurality of connecting shafts are grouped in pairs, and two in a group of connecting shafts are respectively arranged at both ends of the synchronous pulley and are in rotatable contact with the outer wall of the synchronous pulley.

[0013] Further, rotation holes are formed in a group of connecting shafts, and both ends of the synchronous pulley can be movably and rotatably received in the rotation holes.

[0014] Further, the conveyor belt component has a tensioning member which is elastically connected to the synchronous pulley so that the synchronous pulley can rotatably contact the side of the rotation hole close to the conveying channel.

[0015] The advantages of the continuous vegetable harvester with the function of cutting stems and leaves according to the present utility model compared with the prior art are as follows:

[0016] By arranging a defoliating and harvesting mechanism at the first station, the separation and cutting of stems and leaves are synchronously completed during the harvesting process, avoiding the cumbersome steps of subsequent separate defoliation, and greatly improving the harvesting efficiency and continuous operation ability.

[0017] After the material enters the receiving area, it is immediately cut by the cutting component, and then is transmitted through the conveying channel communicated with the receiving area, ensuring the continuity of material processing.

[0018] Almost no manual intervention is required during the entire harvesting process. From the separation of stems and leaves to cutting and then to transmission, the process is fully automated, significantly reducing the labor intensity and at the same time reducing the labor cost.

Detailed Description of the Preferred Embodiments

[0026] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] Embodiment 1, referring to Figure 1 - Figure 2 , a continuous vegetable harvester with a function of removing stems and leaves provided in this embodiment is designed to optimize the harvesting process of leafy vegetables such as lettuce and improve the operation efficiency. The main body of the harvester includes a frame 10, a leaf - removing and harvesting mechanism, and a conveying mechanism. The frame 10 is made of high - strength and lightweight materials, such as aluminum alloy or stainless steel, to ensure a strong structure and reduce the overall weight. Installation frames are equipped on the left and right sides at the top of the frame 10. The installation frames gradually slope upward from the front end to the rear end and naturally extend at the end to form an operation handle. The first working station is set at the front end of the frame 10, in front of the installation frame, and the second working station is formed by the two installation frames together and is located in the middle of the frame 10.

[0028] On the front and rear sides of the bottom of the frame 10, a set of rollers is provided on each side. The front wheels are responsible for flexible steering to ensure that the harvester can adapt to complex field terrains. The rear wheels are driven by a high-efficiency motor, which is connected to the rollers through a precise gear or chain drive system to provide stable and strong power. The motor can choose an internal power source, such as a high-performance lithium battery, to reduce dependence on external power sources and enhance the flexibility of operation. At the same time, the harvester is built-in with a Bluetooth or Wi-Fi module as an interface for wireless communication, which is responsible for receiving command signals from the operator's handheld device (such as a smartphone, tablet, or dedicated remote control).

[0029] The leaf-removing harvesting mechanism is installed at the first working station. The leaf-removing harvesting mechanism has a leaf-removing component 20 and a cutting component 30. This mechanism includes the leaf-removing component 20 and the cutting component 30. The leaf-removing component 20 is responsible for removing the leaves of the lettuce during the harvesting process, while the cutting component 30 is used to cut the stem of the lettuce. A receiving area is provided between the leaf-removing component 20 and the cutting component 30 for temporarily storing the materials to be cut. The conveying mechanism is located at the second working station of the frame 10 and has a conveying channel 401, which is connected to the receiving area and is responsible for conveying the cut lettuce.

[0030] At the rear end of the frame 10, a packing mechanism is also provided. The packing mechanism includes a storage box 50, a counter, and a weighing device. The storage box 50 is firmly installed at the rear end of the frame 10, exactly below the outlet of the conveying channel 401, ensuring that the cut lettuce can directly fall into the box, avoiding additional handling steps and reducing the material handling time. The counter is set on the operating handle, and its sensing end is precisely aligned with the outlet of the conveying channel 401, which can real-time monitor the number of lettuces passing through the outlet and provide immediate harvesting statistical information for the operator. The counter can adopt optical sensor or proximity sensor technology. When the lettuce passes through the outlet of the conveying channel 401, the sensor will detect the occlusion or proximity signal, thereby triggering the counting mechanism to record each passing of the lettuce. On the operating handle, in addition to the counter, a small display screen can also be integrated to display information such as the current number of lettuces, operating time, and equipment status, facilitating the operator to keep track of the operation progress at any time. The weighing device is installed on the frame below the storage box 50, and it is mainly used to measure the weight of the lettuce.

[0031] When the harvester moves forward in the field, the lettuce enters from the front end of the frame 10. First, the unnecessary leaves are removed through the leaf-removing component 20, and then it enters the receiving area. In the receiving area, the cutting component 30 precisely cuts the stem of the lettuce. The cut lettuce is then conveyed through the conveying channel 401 of the conveying mechanism to the other end of the harvester and falls into the storage box 50, completing the entire harvesting process.

[0032] A continuous vegetable harvester provided in this embodiment realizes the automation and continuity of lettuce harvesting through integrated leaf removal and cutting functions, combined with an efficient conveying system, greatly improving the harvesting efficiency and operation quality, reducing subsequent processing steps, and meeting the requirements of large-scale agricultural production.

[0033] Embodiment 2, referring to Figure 3 , on the basis of the above embodiment, the leaf removal component 20 has a groove plate 201, a rotating rod 202 and a fixed rod 203 vertically arranged at the first station. The rotating rod 202 and the fixed rod 203 are respectively passed through both sides of the groove plate 201. The rotating rod 202 is in threaded cooperation with the groove plate 201, and the fixed rod 203 is in slidable cooperation with the groove plate 201.

[0034] During specific implementation, the groove plate 201 can be a rectangular plate with a circular through-hole opened in the middle part. An installation frame can be set at the front end of the frame 10. The rotating rod 202 and the fixed rod 203 are symmetrically and vertically arranged on both sides of the installation frame respectively. The two ends of the rotating rod 202 are connected to the installation frame in a rotational cooperation manner to ensure that the rotating rod 202 can rotate freely. The two ends of the fixed rod 203 can be firmly connected to the installation frame by welding. A threaded through-hole is opened on one side of the groove plate 201. At the same time, a matching thread is provided on the rotating rod 202, and the two form a precise threaded connection method. By rotating the rotating rod 202, the groove plate 201 can move up and down along its axis direction, thereby adjusting the distance between the circular through-hole and the lettuce stem. On the other side of the groove plate 201, a smooth sliding hole is opened, and the fixed rod 203 is passed through the sliding hole to form a sliding cooperation with the groove plate 201. This design ensures the straightness and stability of the groove plate 201 when moving along the direction of the rotating rod 202, avoiding position deviation caused by friction or resistance.

[0035] A motor is installed on the installation frame. The motor is in transmission connection with the rotating rod 202 through a set of meshing gears. When the motor is started, the rotation of the gears will drive the rotating rod 202 to rotate, thereby changing the position of the groove plate 201 and realizing automatic adjustment.

[0036] Before starting the operation, the slot plate 201 is at the uppermost position, and the circular through hole maintains a certain distance from the ground. As the harvester moves forward, the lettuce is guided to the bottom of the slot plate 201, ready to enter the stem-leaf separation program. The operator starts the motor, and the motor drives the rotating rod 202 in the forward direction, so that the slot plate 201 moves down smoothly along the fixed rod 203. During this process, the circular through hole gradually approaches the lettuce. When the circular through hole contacts the lettuce, the stem passes through the through hole smoothly, while the leaves are removed due to the friction force because they cannot pass through the restriction of the circular through hole, thereby achieving effective separation of the stem and leaves. After the separation of the stem and leaves is completed, the operator controls the motor to reverse, and the motor drives the rotating rod 202 to rotate in the opposite direction. The slot plate 201 then rises along the fixed rod 203 and returns to its initial position, ready for the next round of stem-leaf separation operation.

[0037] Embodiment 3, based on the above embodiment, the cutting assembly 30 has a cutting disk 301, and the cutting disk 301 can be rotatably set on the second workstation, and the groove plate 201 has an anti-falling side, which is set on a side close to the cutting disk 301, and the anti-falling side is parallel to the axial direction of the cutting disk 301.

[0038] During specific implementation, the cutting disc 301 is located at the second station of the frame 10, which is arranged after the leaf removal component 20 and close to the entrance of the conveying channel. This layout ensures that the lettuce stem after leaf removal can directly enter the cutting area of the cutting disc 301, realizing a seamless operation process. The cutting disc 301 is driven by a special motor, which is connected to the main shaft of the cutting disc 301 through a belt or gear transmission system. The anti-falling side is a component of the slot plate 201, located on the side close to the cutting disc 301, and its design purpose is to prevent the lettuce stem from deflecting or flipping during the cutting process, ensuring the flatness and consistency of the cutting surface. The anti-falling side is parallel to the axial direction of the cutting disc 301, forming a straight line, and its height is slightly higher than the highest point of the cutting disc 301 to provide sufficient support. The surface of the anti-falling side can be smooth to reduce friction, or with a slight protrusion to increase the guiding stability.

[0039] During the cutting process, as the cutter moves forward, the lettuce stems after leaf removal enter the cutting area of the cutting disc 301. At this time, the role of the anti-tilt function is crucial. It not only prevents the stems from shifting under the action of the high-speed rotating cutting disc 301, but also ensures that the stems can be cut along a straight line trajectory, thereby obtaining a smooth cutting surface and improving the quality and commercial value of the lettuce.

[0040] Embodiment 4, based on the above embodiment, the conveying mechanism has two sets of conveyor belt assemblies, and along the extension direction of the conveying channel 401, the two sets of conveyor belt assemblies are respectively arranged on both sides of the conveying channel 401, and the side of the two sets of conveyor belt assemblies close to the receiving area can at least partially extend into the receiving area.

[0041] During specific implementation, two groups of conveyor belt assemblies are respectively installed on two mounting frames, each mounting frame is provided with a driving wheel and a driven wheel, and a motor for driving. The driven wheel is arranged at one end of the mounting frame close to the receiving area, and part of the driven wheel is located in the receiving area. This design allows the cut lettuce to fall directly onto the conveyor belt, reducing material processing delays and potential blockage risks. The driving wheel and the motor are both arranged at one end of the mounting frame with an operating handle. The driving wheel is directly connected to the shaft of the motor, that is, the output shaft of the motor is connected to the central axis of the driving wheel by a keyway or a spline. When the motor is started, the rotation of its output shaft is directly converted into the rotation of the driving wheel, driving the synchronous belt 403 to move.

[0042] The synchronous belt 403 is tightly connected with the tooth grooves on the driving wheel and the driven wheel through its inner teeth to form a closed-loop transmission system. When the driving wheel rotates, its tooth grooves engage with the teeth of the synchronous belt 403, driving the synchronous belt 403 to move. The synchronous belt 403 then engages with the tooth grooves of the driven wheel through the teeth on the other side, driving the driven wheel to rotate, thereby realizing power transmission. This connection method ensures a constant transmission ratio between the driving wheel and the driven wheel, and can maintain a stable transmission effect even under high load and high speed operation.

[0043] By implementing the optimized design in this example, the conveying mechanism can efficiently handle the cut lettuce, ensuring the continuity from cutting to packaging and improving the overall operation efficiency. The coordinated work of the two sets of conveyor belt components not only reduces the damage of the lettuce during transportation, but also reduces energy consumption and maintenance costs through precise material control.

[0044] Embodiment 5, based on the above embodiments, the conveyor belt assembly has a plurality of synchronous wheels 402 and a synchronous belt 403, the plurality of synchronous wheels 402 are spaced apart toward the conveying channel 401, and the plurality of synchronous wheels 402 are in contact with the synchronous belt 403 and meshed with the synchronous belt 403 for transmission connection.

[0045] During specific implementation, a number of synchronous wheels 402 are spaced apart along the direction of the transmission channel 401, and each synchronous wheel 402 is fixed on a mounting frame, ensuring stable support of the synchronous belt 403 during operation. This spacing setting not only reduces the sagging of the synchronous belt 403, but also ensures uniform distribution of power, thereby improving transmission efficiency.

[0046] The arrangement direction of the synchronous pulley 402 is consistent with that of the conveying channel 401. This design enables the synchronous pulley 402 to better support and guide the synchronous belt 403, avoiding the lateral offset of the synchronous belt 403 during operation, ensuring the linearity of material transmission. When the driving pulley rotates, its tooth grooves engage with the teeth of the synchronous belt 403, driving the synchronous belt 403 to move. The synchronous belt 403 then engages with the teeth of the driven pulley and the tooth grooves of the synchronous pulley 402 through its teeth, realizing the transmission of power. This meshing transmission connection method ensures the accuracy and stability of power transmission, reduces energy loss, and avoids slipping at the same time.

[0047] Through the optimized design of this embodiment, several synchronous pulleys 402 and the synchronous belt 403 in the conveyor belt assembly form an efficient and stable transmission system, ensuring the smooth transmission of the cut lettuce, reducing losses and blockages during the material handling process, and improving the overall operation efficiency of the continuous vegetable harvester.

[0048] Embodiment 6, refer to Figure 4 , on the basis of the above embodiment, the conveyor belt assembly has several connecting shafts 404. Several connecting shafts 404 are grouped in pairs. Two of a group of connecting shafts 404 are respectively arranged at both ends of the synchronous pulley 402 and are rotatably abutted against the outer wall of the synchronous pulley 402.

[0049] Specifically, one end of the connecting shaft 404 can be fixed to the mounting bracket by welding or other means. The other end of the connecting shaft 404 is embedded with a bearing. The inner ring of the bearing is tightly fitted with the connecting shaft 404, while the outer ring is fitted with the central hole of the synchronous pulley 402, allowing the synchronous pulley 402 to freely rotate on the connecting shaft 404. The outer walls on both sides of the synchronous pulley 402 form a rotatable abutment with the inner wall of the connecting shaft 404. This design not only ensures the stable rotation of the synchronous pulley 402 but also restricts the displacement of the synchronous pulley 402 in the axial direction, avoiding transmission inaccuracy caused by axial movement, thus ensuring the stable and efficient transmission of lettuce.

[0050] Embodiment 7, refer to Figure 5 , on the basis of the above embodiment, rotation holes 405 are provided on each group of connecting shafts 404. Both ends of the synchronous pulley 402 are respectively movably and rotatably received in the rotation holes 405.

[0051] In specific implementation, the rotation hole 405 is opened at the central position of the connecting shaft 404, running through the length direction of the connecting shaft 404, forming a space that allows the two ends of the synchronous pulley 402 to move freely. The two ends of the synchronous pulley 402 are designed to be movably and rotatably received in the rotation hole 405 of the connecting shaft 404. This design allows the synchronous pulley 402 to make a small displacement in the axial direction when subjected to an external force (such as the impact of a lettuce with unremoved leaves), while maintaining stable contact with the synchronous belt 403 in the radial direction, thereby reducing the phenomenon of transmission interruption or blockage caused by the lettuce leaves getting stuck.

[0052] By allowing the small displacement of the synchronous pulley 402 in the axial direction, the risk of transmission blockage caused by unremoved lettuce leaves is effectively reduced, improving the stability and operation efficiency of the continuous vegetable harvester.

[0053] Embodiment 8, referring to Figure 6 , on the basis of the above embodiment, the conveyor belt assembly has a tensioning member 406, and the tensioning member 406 is elastically connected to the synchronous pulley 402, so that the synchronous pulley 402 is rotatably abutted against the side of the rotation hole 405 close to the conveying channel 401.

[0054] In specific implementation, the tensioning member 406 can be a tension spring. The tension spring is usually arranged on the side of the synchronous pulley 402, corresponding to the side of the rotation hole 405 close to the conveying channel 401. One end of the tension spring is fixed at a fixed point on the frame 10 or the mounting bracket, and the other end is elastically connected to the synchronous pulley 402. This elastic connection can usually be achieved through hooks, buckles or other types of connectors.

[0055] The tension force provided by the tension spring ensures the stable contact between the synchronous pulley 402 and the synchronous belt 403. Even in the case of high-speed operation or load changes, the continuity and stability of the transmission can be maintained. More importantly, through the setting of the tensioning member 406, the transmission channel can achieve adaptive adjustment to cope with the challenges brought by the lettuce with unremoved leaves.

[0056] When encountering a lettuce with unremoved leaves, under the action of the tension force of the tension spring, the synchronous pulley 402 can make a small axial displacement according to the resistance of the leaves. This dynamic response mechanism allows the synchronous pulley 402 to reduce the direct impact of the leaves on the transmission system while maintaining contact with the synchronous belt 403, avoiding transmission interruption or equipment damage that may be caused by the leaves getting stuck. When the leaves pass through, the synchronous pulley 402 will automatically return to its original position, and the tension force of the tension spring will also recover accordingly, ensuring the stability and continuity of the transmission system.

[0057] Through the design of this embodiment, not only the stability and continuity of the synchronous belt 403 drive system are ensured, but also the interference that the lettuce with incompletely removed leaves may cause to the drive system is effectively addressed through the adaptive adjustment function. This design significantly improves the adaptability and operation efficiency of the continuous vegetable harvester, reflecting the advancement and practicality of modern agricultural machinery design.

[0058] Working principle:

[0059] When harvesting lettuce, the operator starts the equipment through the control panel on the operation handle, activates the motor, cutting assembly 30 and conveying mechanism, and prepares to start the harvesting operation. Lettuce and other vegetables are sent into the area of the leaf-removing assembly 20 through the guiding device at the front end of the frame 10. The lettuce stem passes through the circular through-hole on the trough plate 201, while the leaves are removed due to the restriction of the circular through-hole and the action of friction, achieving the preliminary separation of the stem and leaves.

[0060] After passing through the leaf-removing assembly 20, the stem enters the receiving area. The cutting disc 301 rotates at high speed driven by the motor to precisely cut the stem. The cut lettuce stem is then smoothly conveyed to the conveying channel 401 by two groups of conveyor belt assemblies, and finally falls into the storage box 50 located at the rear end of the frame 10 after being conveyed through the conveying channel 401.

[0061] In this specification, when referring to multiple explanatory embodiments, it means that the specific structure described in combination with this embodiment is included in at least one embodiment generally described in this application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when describing a structure in combination with any one embodiment, what is claimed is that implementing this structure in combination with other embodiments falls within the scope of the present utility model.
