Description

Technical Field

[0001] This invention relates to the field of cabbage planting and harvesting technology, and in particular to an integrated small auxiliary device for cabbage planting and harvesting. Background Technology

[0002] Chinese cabbage is widely cultivated throughout China. When mature, the plant grows to a height of 40-60 cm, with a main body that is obovate-oblong to obovate in shape, and is 30-60 cm long and wide.

[0003] Normally, harvesting cabbage requires workers to bend over and cut the cabbage stems with a sickle before removing the cabbage. After harvesting, the remaining stems in the soil also need to be manually pulled out. Therefore, harvesting cabbage is very labor-intensive and somewhat dangerous. Nowadays, to save labor and meet the needs of large-scale planting, large-scale cabbage farms and farmers often use various large cabbage harvesters. This greatly saves labor, but for small farmers or farmers in remote areas, these machines are too expensive, and their large size and complex operation make them unsuitable for small- to medium-sized or individual planting needs.

[0004] Chinese cabbage can be sown in rows. The specific method involves making a shallow furrow 0.5-1.0 cm deep in the center of the ridge, evenly scattering the seeds in the furrow, and then covering with soil and compacting. The seed rate is approximately 120 grams per 667 square meters. Alternatively, a Chinese cabbage seeder can be used, sowing at the top center of the ridge. The seed rate is 80-100 grams per 667 square meters. The seeder should be equipped with soil covering and compaction devices. However, existing machinery is too limited in its function, only addressing the sowing of Chinese cabbage and unable to play a role in other stages of the Chinese cabbage life cycle.

[0005] Chinese Patent Publication No. CN108811780B discloses a method for harvesting vegetables after they have matured, comprising the following steps: Step 1: Prepare a shovel and a collection box; Step 2: Insert the shovel into the soil and push it along the direction of vegetable planting; Step 3: Collect the shoveled vegetables into the collection box; Step 4: Remove the vegetable roots remaining in the soil; Step 5: Crush and collect the vegetable roots. The aim is to solve the problem that in current cabbage harvesting processes, harvesters cut off the cabbage roots, leaving them in the soil, and the length of each part of the device is not adjustable. Therefore, this device does not consider the role it plays in other stages of the cabbage life cycle, nor does it take into account the different planting conditions and the needs of users of different heights. Summary of the Invention

[0006] Therefore, the present invention provides a small auxiliary device for integrated planting and harvesting of cabbage, which overcomes the problems of existing machines being too large, not taking into account the height of different operators, too expensive, and having too limited function.

[0007] To achieve the above objectives, the present invention proposes a small-scale auxiliary device integrating cabbage planting and harvesting, comprising:

[0008] The mobile vehicle includes a supporting and moving mechanism and a handheld adjustment connection. The supporting and moving mechanism includes four rubber wheels, a frame mounted above the rubber wheels, and a first support plate and a second support plate mounted on the upper surface of the frame. The handheld adjustment connection includes a central supporting rod, which is kept parallel to the ground via the first and second support plates. A sliding support frame is rotatably and slidably connected to the central supporting rod.

[0009] A sowing mechanism includes a sowing wheel, a connecting part connected to the axis of the sowing wheel to support the rotation of the sowing wheel along the axis, and a sowing connection head for connecting the sowing mechanism to a handheld seed harvesting control lever assembly; wherein, the rim of the sowing wheel is evenly provided with a plurality of sowing parts, each sowing part including a wedge-shaped slider and a small spring connected inside the sowing wheel;

[0010] A harvesting mechanism includes a cutting blade arranged opposite to each other, two flexible auxiliary clamping straps arranged opposite to each other above the cutting blade, a harvesting connection head for connecting the harvesting mechanism to a hand-held seed harvesting control rod assembly, and clamping parts arranged opposite to each other for loading the cutting blade and the flexible auxiliary clamping straps, for cutting cabbage by the opposing movement of the cutting blade, and for clamping and fixing the side of the cabbage by the two flexible auxiliary clamping straps moving closer to each other.

[0011] The handheld seeding and harvesting control lever assembly includes a first lever assembly, a second lever assembly, a special-shaped fixing bolt, and a sliding support frame arranged in a scissor-like configuration. The first lever assembly and the second lever assembly are stacked vertically in an X-shape and connected by the special-shaped fixing bolt in an X-shape. The harvesting mechanism or the seeding mechanism can be detachably installed on the front ends of the first lever assembly and the second lever assembly. The lengths of the front and rear ends of the first lever assembly and the second lever assembly away from the special-shaped fixing bolt are adjusted by corresponding adjusting rods.

[0012] An auxiliary bulldozing mechanism, which is installed under the mobile vehicle body, includes a bulldozing plate with an adjustable height relative to the ground;

[0013] An auxiliary detection mechanism, which is connected to the handheld seed harvesting control lever assembly, is used to detect the furrowing depth and seeding quantity in real time;

[0014] A control and adjustment mechanism, connected to the auxiliary detection mechanism, is used to determine soil hardness based on the detected trenching depth, determine the soil covering height of the auxiliary bulldozing mechanism based on the detected trenching depth, and control the soil covering height of the auxiliary bulldozing mechanism to adjust the sowing depth based on the detected current sowing density and the soil hardness. The seed sowing density is adjusted by adjusting the compression of the small spring.

[0015] An alarm mechanism is connected to both the auxiliary detection mechanism and the control and adjustment mechanism, and performs an alarm operation upon receiving an alarm signal from the control and adjustment mechanism.

[0016] Furthermore, the connecting part of the sowing mechanism includes a first sowing support rod and a second sowing support rod symmetrically arranged on both sides of the rotation center of the sowing wheel, and the sowing wheel is rotatably connected to the first sowing support rod and the second sowing support rod;

[0017] The two seeding connection heads are rotatably connected to the front ends of the first rod group and the second rod group, respectively, to adjust the forward direction of the seeding wheel.

[0018] Furthermore, the seeding wheel is a double-sided conical wheel with left and right symmetry, which includes a left half seeding wheel and a right half seeding wheel. They are symmetrically installed at the ends of the first seeding support rod and the second seeding support rod. Each half seeding wheel has a conical outer surface and equally spaced slots on one side of the rim. The slots of the left half seeding wheel and the right half seeding wheel are correspondingly arranged to form wedge-shaped through holes.

[0019] The seeding part is installed on the wedge-shaped through hole corresponding to the seeding wheel;

[0020] In a single seeding section, the size of the middle part of the wedge slider near the small end corresponds to the wedge through hole so that the end face of the small end of the wedge slider protrudes from the rim of the seeding wheel, the large end of the wedge slider is located inside the seeding wheel, and the large end of each wedge slider points to the rotation center of the seeding wheel.

[0021] The small springs correspond one-to-one with the wedge-shaped sliders. A single small spring is located at the large end of the wedge-shaped slider. When the small spring is not compressed, it causes the small end of the corresponding wedge-shaped slider to protrude from the rim of the seeding wheel. When compressed, it causes the small end of the wedge-shaped slider to move closer to the rotation center of the seeding wheel, so that a gap is created between the wedge-shaped through hole and the wedge-shaped slider.

[0022] Furthermore, a seed storage chamber is provided inside the seeding wheel. The storage chamber is connected to the gap generated by the wedge-shaped through hole and the wedge-shaped slider, respectively, so as to put the seeds into the gap so that the seeds are output to the outside of the seeding wheel through the gap.

[0023] Furthermore, the first and second lever groups of the handheld seed harvesting control lever assembly have the same structural composition. Each lever group includes a central lever, a front adjusting lever, a rubber handle, a rear adjusting lever, and a wire-driven control rod, wherein:

[0024] The middle rod of the first rod group and the middle rod of the second rod group are fixed to the upper part of the sliding support frame in an X-shape by the special-shaped fixing bolts. Each middle rod can rotate circumferentially relative to the axis of the special-shaped fixing bolts.

[0025] The front adjusting rod is mounted on the front end of the middle rod;

[0026] The rear adjustment rod is installed at the rear end of the middle rod;

[0027] The rubber handle is mounted on the rear end of the rear adjustment rod;

[0028] The wire-driven control rod is installed in the groove of the rubber handle, and the sliding direction of the wire-driven control rod is towards or away from the end of the rubber handle.

[0029] The sliding support frame is slidably mounted on the middle of the central support rod above the mobile vehicle body, so as to slide along the axial direction of the central support rod and rotate along the radial direction of the central support rod; the sliding support frame restricts the rotation range of the first rod group and the second rod group through the first support plate and the second support plate.

[0030] Furthermore, the harvesting mechanism is mounted on the front end of the front adjusting rod via the harvesting connecting head, and its extension length can be adjusted via the front adjusting rod; a single harvesting connecting head is connected to the clamping part to realize the connection between the harvesting mechanism and the handheld seed harvesting control rod assembly;

[0031] The clamping part includes a left clamping frame and a right clamping frame that are symmetrically arranged at the front end of the first rod group and the second rod group with the same structure. Each clamping frame has an inverted N-shaped structure and includes two vertical rods for fixing the flexible auxiliary clamping belt and a horizontal rod connecting the lower part of the two vertical rods. A single cutting tool is fixed on the horizontal rod by a buckle.

[0032] The two cutting tools are arranged opposite each other on the inner sides of the left and right clamping frames, and the flexible auxiliary clamping band is arranged on the upper side of the cutting tools.

[0033] Furthermore, the bulldozer blade is a V-shaped retaining plate, with its V-shaped opening side close to the seeding wheel.

[0034] Furthermore, the control and adjustment mechanism determines the soil covering height of the auxiliary bulldozing mechanism by comparing the detected trenching depth with the preset depth.

[0035] Furthermore, the control and adjustment mechanism is equipped with a set correlation between furrowing depth and soil hardness under the weight of the seeding wheel, and the control and adjustment mechanism determines the soil hardness based on the detected furrowing depth in the correlation.

[0036] Furthermore, the control and adjustment mechanism determines the sowing parameters based on the detected current sowing density and the soil hardness, and determines whether to adjust the soil covering height of the auxiliary bulldozing mechanism to adjust the sowing depth by comparing the sowing parameters with the preset sowing parameters.

[0037] Compared with the prior art, the beneficial effects of the present invention are that, compared with the common large cabbage harvester, the present invention is lightweight, easy to install and use, and can meet the cabbage planting and harvesting needs of small and medium-sized farmers. Moreover, it is completely driven by human power, consumes no fuel or electricity, has high safety, good reliability, saves energy, and is green and environmentally friendly.

[0038] Furthermore, the integrated small auxiliary device for cabbage planting and harvesting of the present invention has a simple connecting part structure for the sowing mechanism, which is easy to disassemble and install, and easy to replace.

[0039] Furthermore, the small auxiliary device for integrated cabbage planting and harvesting of the present invention has a simple sowing wheel structure that combines sowing and ditching functions, making it a multi-purpose machine with a low price and strong practicality.

[0040] Furthermore, the small auxiliary device for integrated cabbage planting and harvesting of the present invention has a seeding wheel that can precisely control the seeding amount, preventing waste caused by excessive seeding, controlling seeding costs, and achieving precise seeding.

[0041] Furthermore, the present invention provides a small auxiliary device for integrated cabbage planting and harvesting, wherein the first rod group and the second rod group form a lever structure with irregularly shaped fixing bolts as fulcrums. The lever principle can be used to bring the two cutting blades closer to each other, and the linear transmission controls the blades to move and cut the cabbage roots. This method is more labor-saving than the traditional manual root cutting method, and the user does not need to bend over to work, resulting in lower labor intensity, improved harvesting efficiency, and the blades are further away from the user, making it safer.

[0042] Furthermore, the small auxiliary device for integrated cabbage planting and harvesting of the present invention has adjustable lengths for each part, making it adaptable to most planting conditions and users of different heights, and thus highly adaptable.

[0043] Furthermore, the present invention provides a small-scale auxiliary device for integrated cabbage planting and harvesting, which is equipped with an auxiliary bulldozing mechanism. The bulldozing plate gathers and backfills the soil, thereby covering the seeds and meeting the requirements for seed sowing depth.

[0044] Furthermore, the small auxiliary device for integrated cabbage planting and harvesting of the present invention is equipped with a control and adjustment mechanism, which can adjust the sowing depth and sowing density according to the trenching depth, soil hardness and sowing parameters to meet the requirements of seed sowing depth.

[0045] Furthermore, the present invention provides a small-scale auxiliary device for integrated cabbage planting and harvesting, which adds an auxiliary detection mechanism to detect the weight of the seeding wheel, the depth of furrowing, the soil hardness, and the seeding parameters in real time, ensuring the accuracy of the seeding parameters and providing data support for controlling and adjusting the seeding process.

[0046] Furthermore, the small auxiliary device for integrated cabbage planting and harvesting of the present invention adds an auxiliary detection mechanism and an alarm mechanism to transmit alarm signals to the operator for reminder, so that the operator can know the sowing status, ensure the normal progress of the sowing process, and prevent the operator from operating the machine incorrectly due to lack of sowing information, thereby avoiding the impact of insufficient seed quantity on yield, and avoiding the impact of wind and drought on seeds due to insufficient furrow depth, or the impact of excessive furrow depth on seed germination rate.

[0082] The back panel 503 of the outer casing is installed in the rear sliding groove of the outer casing body 501.

[0083] The outer shell back plate 503 can prevent sand and gravel from entering the mobile vehicle body and affecting the normal operation of the main body of the device.

[0084] Please see Figure 11 and Figure 12 As shown, Figure 11 This is a schematic diagram of the seeding mechanism. Figure 12 This is a schematic diagram of the detailed structure at point B;

[0085] Specifically, the connecting part of the sowing mechanism includes a first sowing support rod and a second sowing support rod symmetrically arranged on both sides of the rotation center of the sowing wheel, and the sowing wheel is rotatably connected to the first sowing support rod and the second sowing support rod;

[0107] The clamping part includes a left clamping frame and a right clamping frame that are symmetrically arranged at the front end of the first rod group 1 and the second rod group 2. Each clamping frame has an inverted N-shaped structure and includes two vertical rods for fixing the flexible auxiliary clamping belt and a horizontal rod connecting the lower part of the two vertical rods. A single cutting tool is fixed on the horizontal rod by a buckle. The buckle of the single cutting tool is connected to the sliding component. The reciprocating motion of the cutting tool on the horizontal rod is realized by the traction of the control line.

[0108] The cutting blades are positioned opposite each other on the inner sides of the left and right clamping frames, and the flexible auxiliary clamping band is positioned on the upper side of the cutting blades.

[0109] In a specific embodiment, taking the first rod group 1 as an example, the extension length of the first front adjusting rod 102 can be adjusted by being installed in different positions, allowing for seven levels of adjustment to adapt the device to various ridge heights; the extension length of the first rear adjusting rod 105 can be adjusted by being installed in different positions, allowing for ten levels of adjustment to adapt the device to the height differences between different users. The first flexible auxiliary clamping strap 106 and the second flexible auxiliary clamping strap 206 can assist in clamping the cabbage, keeping the cabbage in an upright posture and minimizing damage to the cabbage leaves; the first cutting blade 107 and the second cutting blade 207 are installed on the buckles on the lower side of the left and right clamping frames through side-shaped slots.

[0110] Specifically, the bulldozer 6 is a V-shaped retaining plate, with its V-shaped opening side close to the seeding wheel.

[0111] Please see Figure 13 As shown, Figure 13Workflow diagram for detection and control alarm mechanism;

[0112] Specifically, the control and adjustment mechanism determines the soil covering height of the auxiliary bulldozing mechanism by comparing the detected trenching depth with the preset depth.

[0113] During implementation, the auxiliary bulldozing mechanism is pre-set with a standard trenching depth. Generally, the soil covering height is set to be the same height as the ground or slightly higher than the ground height.

[0114] If the detected trench depth is less than the preset depth, it is determined that the soil covering height of the auxiliary bulldozing mechanism needs to be increased, and the bulldozing plate is moved up.

[0115] If the detected trench depth is greater than or equal to the preset depth, it is determined that there is no need to increase the soil covering height of the auxiliary bulldozing mechanism.

[0116] It is understood that the preset depth is determined based on the guide planting depth range of the seeds. For example, the guide planting depth range for cabbage seeds is 10-15mm, and preferably the median value of 12.5mm within the guide planting depth range is taken as the preset depth.

[0117] In practice, the increase in the soil covering height of the auxiliary bulldozing mechanism is determined based on the difference between the detected trench depth and the preset depth, and the soil covering height is adjusted by adjusting the height of the bulldozing plate.

[0118] If the trenching depth is Hs and the preset trenching depth is h0, if Hs < h0, then the soil covering height of the auxiliary bulldozing mechanism needs to be increased; calculate the difference Ha between h0 and Hs, where Ha is the soil covering height of the bulldozing plate; if Hs ≥ h0, then it is determined that the soil covering height of the auxiliary bulldozing mechanism does not need to be increased.

[0119] Specifically, the control and adjustment mechanism is equipped with a set correlation between furrow depth and soil hardness under the weight of the seeding wheel, and the control and adjustment mechanism determines the soil hardness based on the detected furrow depth in the correlation.

[0120] It is understandable that different seeding wheel weights result in different furrow depths for the same planting soil. Therefore, through several sets of experiments, a comparison table of furrow depth and soil hardness under different seeding wheel weights can be obtained. Under a certain seeding wheel weight, the control and adjustment mechanism determines the soil hardness based on the detected furrow depth in the comparison table.

[0121] Specifically, the control and adjustment mechanism determines the sowing parameters based on the detected current sowing density and the soil hardness, and determines whether to adjust the soil covering height of the auxiliary bulldozing mechanism to adjust the sowing depth by comparing the sowing parameters with the preset sowing parameters.

[0122] In practice, the seeding parameter H is determined according to the following formula:

[0123] ;

[0124] Where N represents the sowing density, N0 represents the standard sowing density, G represents soil hardness, and G0 represents the standard soil hardness. In practice, G0 is generally set to the guide soil hardness for the corresponding seeds in the planting guidelines, and N0 is generally set to the guide sowing density for the corresponding seeds in the planting guidelines. The sowing density is calculated based on the number of seeds (Na) sown per unit sowing length, where N = Na / L, and L is the unit sowing length in meters.

[0125] Specifically, the control and adjustment mechanism determines whether to adjust the soil covering height of the auxiliary bulldozing mechanism to adjust the sowing depth based on the comparison result of the sowing parameter H and the preset sowing parameter H0, including:

[0126] If H < H0, the control and adjustment mechanism determines to adjust the sowing depth and reduces the soil covering height after the auxiliary bulldozing mechanism adjusts according to the trenching depth;

[0127] If H≥H0, the control and adjustment mechanism determines that there is no need to adjust the sowing depth and sets the soil covering height of the auxiliary bulldozing mechanism to the soil covering height adjusted according to the trenching depth.

[0128] In practice, the preset seeding parameter is preferably set to 1, and the preset seeding parameter can be selected in the range of 0.9 to 1.3.

[0129] Specifically, when H < H0, the control and adjustment mechanism determines to adjust the sowing depth. When the soil covering height adjusted by the auxiliary bulldozing mechanism according to the furrowing depth is reduced, the reduced soil covering height H' is determined according to the following formula:

[0130] H' = Ha × H,

[0131] Where Ha is the soil cover height adjusted according to the trench depth, Ha=h0-Hs; Hs is the current trench depth detected, and h0 is the preset depth.

[0132] Specifically, in practice, the seed sowing density can be adjusted by adjusting the compression amount or spring stiffness of the small spring 810. It is understood that the smaller the compression amount of the small spring 810 or the larger the spring stiffness, the smaller the gap formed by the wedge slider 809 and the wedge through hole, and the smaller the amount of seeds sown into the soil through the gap.

[0133] In this embodiment, the auxiliary detection mechanism includes a sensor used to detect furrow depth and sowing density, and transmits the detected data to the control and adjustment mechanism and the alarm mechanism. The control and adjustment mechanism consists of a drive device and a sensor. The drive device is a small drive motor. The sensor of the control and adjustment mechanism processes the data transmitted by the sensor of the auxiliary detection mechanism.

[0134] In this embodiment of the invention, the sensor used to detect the furrow depth in the auxiliary detection mechanism can be a laser triangular reflective displacement sensor, which can detect the actual value of the furrow depth in real time and is installed on the lower surface of the mobile vehicle body shell; the sensor also includes a sensor for detecting the weight of the seeding wheel, which can determine and calculate the real-time seeding amount by detecting the weight change of the seeding wheel in real time; after the sensors for detecting the actual value of the furrow depth and the sensors for detecting the weight change of the seeding wheel in real time detect the information, they transmit the information to the sensor of the control and adjustment mechanism; it is understood that the specific detection method used by the auxiliary detection mechanism is not limited here, and all of them fall within the protection scope of this invention, and will not be elaborated here.

[0135] In this embodiment, it is installed in the bulldozer blade 6 and the seeding wheel. The drive motor is connected to the bulldozer blade 6 and the small spring 810. The sensor of the control and adjustment mechanism receives information from the auxiliary detection system and calculates whether the soil covering height needs to be adjusted. If the soil covering height does not need to be adjusted, the sensor of the control and adjustment mechanism does not perform any operation. If the soil covering height needs to be adjusted, the sensor transmits the information to the drive device and the alarm mechanism. The drive device drives the adjustment of the height between the bulldozer blade 6 and the ground to adjust the soil covering height to adjust the seeding depth, and the alarm mechanism sounds an alarm.

[0136] Meanwhile, the sensor of the control and adjustment mechanism receives the real-time sowing amount and calculates the sowing density. The drive device adjusts the sowing density by adjusting the compression of the small spring 810, thereby adjusting the soil covering height. At the same time, the sensor of the control and adjustment mechanism transmits a signal to the alarm mechanism. When the adjustment is completed, the signal is transmitted to the alarm mechanism to clear the alarm.

[0137] Specifically, the alarm mechanism consists of a sensor and a horn; after receiving the alarm command from the control and adjustment mechanism, the sensor alerts the operator through the horn; when the adjustment is completed, the alarm mechanism receives an alarm cancellation command and cancels the alarm.

[0138] In this embodiment, when the alarm mechanism's sensor receives an alarm notification, the operator is informed that they need to stop moving forward to sow the seeds and wait in place for the control and adjustment mechanism to make adjustments. When the auxiliary detection mechanism identifies in real time that the furrow depth and sowing density are within the guided planting depth range, it transmits an instruction to the control and adjustment mechanism. The control and adjustment mechanism stops operating and transmits a signal to the alarm mechanism to clear the alarm. The operator can then continue to push the sowing device to sow the seeds. Once the conditions for planting cabbage are met, the alarm is cleared.

[0139] The workflow of this invention includes:

[0140] During harvesting, the user installs the first harvesting connector head 103 and the second harvesting connector head 203 on the front end of the first pole group 1 and the second pole group 2. The user manipulates the first rubber handle 104 and the second rubber handle 204 to move and turn the entire device in the field. When harvesting cabbage, the user aligns the first cutting blade 107 and the second cutting blade 207 with the cabbage root, first uses the first flexible clamping strap 106 and the second flexible clamping strap 206 to clamp the cabbage body, presses down on the first rubber handle 104 and the second rubber handle 204 to pull out the cabbage, then applies horizontal force to bring the two cutting blades closer together, and pulls the first wire drive control rod 108 and the second wire drive control rod 208 by hand to make the two cutting blades move alternately until the cabbage root is cut off. After that, the user moves the first pole group 1, the second pole group 2 and the sliding support frame 4 horizontally and rotates the two rubber handles to place the cabbage in the collection vehicle next to it, completing the entire cabbage harvesting process.

[0141] During sowing, the user manipulates the two rubber handles to move and turn the entire device in the field. When planting cabbage, the cabbage seeds are placed in the cavity formed between the left half of the sowing wheel 804 and the right half of the sowing wheel 805. As the entire device moves forward, the sowing wheel rolls forward and completes the furrowing operation. The groove in the circumferential direction of the sowing wheel is the sowing position. When not in operation, the small spring 810 will push up the wedge-shaped slider 809 to completely close the groove. When in operation, the small spring 810 will be compressed, and a gap will be created between the wedge-shaped slider 809 and the groove, allowing the seeds to fall out of the groove under the action of gravity, completing the evenly spaced sowing operation. The bulldozer plate 6 behind the sowing wheel will gather and backfill the soil brought out by the sowing wheel as it moves forward, completing the cabbage sowing process. The auxiliary detection mechanism, control and adjustment mechanism, and alarm mechanism play a role in real-time monitoring, reminders, and control during sowing to ensure the sowing depth and sowing density of the cabbage seeds.
