[0077] The structural principle and working principle of the present invention are described in detail below in conjunction with the accompanying drawings:

[0078] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a leaf vegetable harvester according to an embodiment of the present invention. Figure 2 for Figure 1 The leafy vegetable harvester of the present invention comprises a walking chassis 1, a cutting device 2, a leafy vegetable orderly conveying and collecting device 3 and a depth-limiting wheel 4. The walking chassis 1, the cutting device 2 and the depth-limiting wheel 4 can all be installed or connected to a frame 31 of the leafy vegetable orderly conveying and collecting device 3. The walking chassis 1 comprises a walking wheel 11 and a chassis driving mechanism 12 connected to the walking wheel 11. As the composition, structure, relative positional relationship, connection relationship and functions of other parts of the leafy vegetable harvester are relatively mature prior arts, they will not be described in detail here. Only the leafy vegetable orderly conveying and collecting device 3 of the present invention will be described in detail below.

[0079] See also Figure 3-Figure 5 , Figure 3 Schematic diagram of the structure of the longitudinal conveying mechanism 32 according to an embodiment of the present invention. Figure 4 Schematic diagram of the structure of the lateral conveying mechanism 33 according to an embodiment of the present invention. Figure 5The figure is a schematic diagram of the installation angle of the transverse conveying mechanism 33 of an embodiment of the present invention. In this embodiment, the leafy vegetable orderly conveying and collecting device 3 includes: a frame 31; a longitudinal conveying mechanism 32, which is installed on the frame 31 and is used to convey the cut vegetables backward; the longitudinal conveying mechanism 32 includes a longitudinal driving motor 321, an active roller 323, a driven roller 325 and a longitudinal conveying belt 324, and the longitudinal driving motor 321 is connected to the active roller 323 through a longitudinal coupling 322; the longitudinal conveying belt 324 is tensioned on the active roller 323 and the driven roller 325; the transverse conveying mechanism 33 is installed on the frame 31 and spans above the longitudinal conveying mechanism 32, and is used to push the leafy vegetables on the longitudinal conveying mechanism 32 to the leafy vegetable collection box 342 on the side; the transverse conveying mechanism 33 includes a transverse driving motor 331, a transverse transmission The conveying belt 333, the conveying scraper 334, the active roller 335 and the driven roller 336, the transverse driving motor 331 is connected to the active roller 335 through the transverse coupling 332, and the transverse conveyor belt 333 is tensioned on the active roller 335 and the driven roller 336; the conveying scraper 334 is installed on the transverse conveyor belt 333, and the conveying scraper 334 is perpendicular to the movement direction of the transverse conveyor belt 333 along the length direction; the leaf vegetable collecting mechanism 34 is installed on the frame 31 and is arranged on one side of the longitudinal conveying mechanism 32 corresponding to the transverse conveying mechanism 33, for carrying and assisting in replacing the leaf vegetable collecting box 342; and the operation control mechanism 36 is arranged on the frame 31 and is respectively connected to the longitudinal conveying mechanism 32 and the transverse conveying mechanism 33.

[0080] The transverse conveying mechanism 33 further includes a scraper reset member 337, which is arranged on the transverse conveyor belt 333 and connected to the conveying scraper 334 to change the angle between the plate surface of the conveying scraper 334 and the transverse conveyor belt 333. There is an inclination angle between the conveying direction of the transverse conveyor belt 333 and the conveying direction of the longitudinal conveyor belt 324 to ensure that there is only a transverse relative movement between the leaf vegetables and the longitudinal conveyor belt 324 during the pushing process of the conveying scraper 334. According to the rotation speed of the battering rod 353, the longitudinal drive motor 321 is controlled to rotate, thereby driving the longitudinal conveyor belt 324 to start operation and complete the longitudinal input of the leaf vegetables. During the backward transportation of the leaf vegetables, the lateral resistance is reduced while ensuring the longitudinal thrust. The longitudinal conveyor belt 324 is preferably a straight stripe conveyor belt.

[0081] The active roller 335 is driven by the transverse driving motor 331 to rotate, so that the transverse conveyor belt 333 equipped with the conveying scraper 334 rotates, and the conveying tube plate is realized to rotate in a circular manner. In order to prevent the rigid connection between the conveying scraper 334 and the transverse conveyor belt 333 from damaging the leafy vegetables during the conveying process, the conveying scraper 334 and the transverse conveyor belt 333 are connected by a scraper reset member 337. The scraper reset member 337 is preferably an elastic reset member 344. When the pressure exceeds a certain force, the angle between the conveying scraper 334 and the transverse conveyor belt 333 can be changed. When the resistance is reduced, the conveying scraper 334 is reset under the action of the elastic reset member 344. In this embodiment, two groups of transverse conveying mechanisms 33 are installed in parallel. The two groups of transverse conveying mechanisms 33 work together to collect all the leafy vegetables in the longitudinal conveying mechanism 32 into the collection box 342. In order to reduce the damage to the leafy vegetables during the conveying process, the transverse conveying mechanism 33 and the longitudinal conveying mechanism 32 are installed at a certain inclination angle, so that the leafy vegetables and the longitudinal conveying mechanism 32 only have a transverse relative movement during the conveying process. Figure 5 As shown, the y direction is the longitudinal conveying direction, the x direction is the horizontal conveying direction, the illustrated placement position is the installation position of the transverse conveying mechanism 33, and its angle with the y direction is α. The speed of the longitudinal conveyor belt 324 is v, and the conveying speed of the longitudinal conveying mechanism 32 is v / sinα.

[0082] See also Figure 6 , Figure 6Schematic diagram of the structure of the weeding mechanism 35 of an embodiment of the present invention. This embodiment also includes a weeding mechanism 35, which is installed on the frame 31 and arranged in front of the longitudinal conveying mechanism 32, and is used to support the stems to cooperate with the cutter for cutting, and timely push the cut grains to the longitudinal conveying mechanism 32. According to the forward speed, the rotation speed of the weeding driving motor 351 is controlled, so that the leafy vegetables can enter the longitudinal conveying mechanism 32 in batches in an orderly manner under the push of the weeding rod 353. The weeding mechanism 35 includes: a mounting plate 354, a plurality of weeding rods 353 are evenly arranged between two mounting plates 354, the weeding rods 353 are arranged at the edge of the mounting plate 354, and the axis of the weeding rod 353 is parallel to the axis of the mounting plate 354; and a weeding driving motor 351, which is connected to the mounting plate 354 through a driving shaft 355, and drives the mounting plate 354 to rotate through the driving shaft 355. The reed-pushing mechanism 35 is connected to the frame 31 through a transverse connecting rod 356 and a longitudinal connecting rod 357, and the two ends of the transverse connecting rod 356 are connected to the frame 31 and the longitudinal connecting rod 357 respectively by bolt fixing; the upper part of the longitudinal connecting rod 357 is connected to the motor mounting plate 352, and the depth limiting wheel 4 is installed at the bottom end of the longitudinal connecting rod 357; the reed-pushing driving motor 351 is installed on the motor mounting plate 352, and the motor mounting plate 352 is connected to the mounting width plate 354 through an axis to form a whole, and the longitudinal connecting rod 357 passes through the motor mounting plate 352 and is tightened and fixed by tightening bolts, thereby realizing the installation of the frame 31, the depth limiting wheel 4 and the reed-pushing mechanism 35. Through the cooperation of the reed-pushing rod 353, the longitudinal conveying mechanism 32 and the transverse conveying mechanism 33, a transverse thrust is applied during the longitudinal conveying of leafy vegetables in batches, and the leafy vegetables are conveyed to the lateral collection box 342 of the harvester.

[0083] The speed of the batten rod 353 is controlled by the batten driving motor 351 according to the forward speed of the implement, and can be changed in real time. The speed is calculated as follows:

[0084] Every time the bat bar 353 rotates one fraction, the distance the implement moves forward is:

[0085] S=V m 60 / mn;

[0086] Wherein, S is the distance that the implement advances in each equally divided time interval of each rotation of the bat bar 353; V m is the forward speed of the implement, in m / s; n is the rotation speed of the bat 353, in r / min; m is the number of equal parts of each bat 353. The mounting plate 354 in this embodiment is a regular pentagon, with a bat 353 mounted in the middle of each side, i.e., the bat 353 is divided into five equal parts.

[0087] Among them, the speed ratio of the reed is: λ=V y / V m; Among them, V y is the circumferential speed, V m The forward speed of the machine.

[0088] When different λ values ​​are taken, the trajectory of the tiller rod 353 will be different. When λ=0, it is a straight line, λ=1 is a rolling cycloid, λ<1 is a short cycloid, and λ>1 is a co-cycloid. Only when the trajectory of the tiller rod 353 is a co-cycloid, the tiller rod 353 will have a backward thrust on the seedlings, so the tiller speed ratio should be greater than 1.

[0089] The straw-pulling speed ratio is a necessary condition for determining the rotation speed of the straw-pulling rod 353. By increasing the straw-pulling speed ratio, the range of action and the degree of operation of the straw-pulling rod 353 will increase. When the forward speed of the machine is constant, it is necessary to increase the straw-pulling speed ratio by increasing the rotation speed of the straw-pulling rod 353. In order to avoid damage to leafy vegetables, the rotation speed of the straw-pulling rod 353 should not be too fast.

[0090] According to the properties of the target vegetables, select the appropriate speed ratio for pulling the straw. According to the speed ratio for pulling the straw and the forward speed of the machine, the speed of the pulling straw bar 353 can be obtained:

[0091]

[0092]

[0093]

[0094] Wherein, n is the rotation speed of the bat bar 353, in r / min; D is the diameter of the bat wheel formed by the bat bar 353 and the mounting plate 354, in m; V m is the left side speed of the machine, in m / s; λ is the reed-pulling speed ratio.

[0095] The longitudinal conveying mechanism 32 of this embodiment conveys the cut leafy vegetables to the rear, and cooperates with the bat-pushing mechanism 35 to transport the leafy vegetables in layers during the conveying process, so its movement speed needs to match the movement speed of the bat-pushing rod 353. If its speed is lower than the speed of the bat-pushing rod 353, the leafy vegetables pushed twice by the bat-pushing rod 353 will overlap, which is not conducive to subsequent orderly collection; if its speed is too high, the same batch of vegetables will be scattered, so the speed of the longitudinal conveyor belt 324 is the same as the speed of the bat-pushing rod 353.

[0096] See also Figure 7 , Figure 7It is a schematic diagram of the structure of the empty box carrying platform 37 of one embodiment of the present invention. This embodiment also includes an empty box carrying platform 37, which is arranged at the rear of the longitudinal conveying mechanism 32. The empty box carrying platform 37 includes a bracket 372 and an empty box storage platform 371. The bracket 372 is connected to the frame 31, and the empty box storage platform 371 is installed on the bracket 372. Among them, the operation control mechanism 36 includes a control console 362 and an armrest 361. The control console 362 is arranged on the platform extending from the empty box carrying platform 37; the armrest 361 is installed on the bracket 372; the control console 362 is respectively connected to the longitudinal drive motor 321, the transverse drive motor 331 and the reed-pulling drive motor 351. The arrangement of the armrest 361 and the empty box storage platform 371 facilitates the operator to perform operation control and place the empty collection box 342 and the control console 362.

[0097] See also Figure 8 , Figure 8 The diagram is a schematic diagram of the structure of the leaf vegetable collection mechanism 34 according to an embodiment of the present invention. The leaf vegetable collection mechanism 34 according to this embodiment includes: a collection frame 341, which is installed on one side of the frame 31; a collection box 342, which is placed in the collection frame 341; a limit rod 343, which is installed at the front end of the collection frame 341, and a hook is provided at the bottom of the limit rod 343, which is used to hook the front end of the collection box 342, so that the collection box 342 can be limited to a limited position until the rear end of the collection box 342 is separated from the collection frame 341 and falls; and a reset member 344, which is respectively connected to the collection frame 341 and the limit rod 343, and is used for resetting the limit rod 343, and the reset member 344 is preferably a reset spring. Since the lateral conveying mechanism 33 is the part close to the cutting device 2 that operates first, it can ensure that the corresponding lower collecting box 342 is filled first. After the collecting box 342 is full, a new collecting box 342 is replaced, and the lower collecting box 342 moves forward under the push of the collecting box 342 at the back. In order to prevent the collecting box 342 from falling directly and contacting the ground first, causing the leafy vegetables in the collecting box 342 to scatter, the limiting rod 343 will hook the upper part of the collecting box 342 until the rear end is separated from the supporting plate of the bottom side frame 31 and the collecting box 342 falls. The limiting rod 343 is quickly reset under the action of the reset spring to limit the position of the next collecting box 342. Since the machine itself moves forward, it can ensure that the leafy vegetables inside the collecting box 342 will not spill.

[0098] When working, after starting the harvester, the forward speed of the machine is controlled by adjusting the button. During the operation, the machine moves forward, and the cutting device 2 cuts the roots of the leafy vegetables by cutting into the soil. The operation control mechanism 36 controls the rotation speed of the reed driving motor 351 according to the forward speed of the machine, thereby driving the reed rod 353 to rotate clockwise at a suitable speed. Each reed rod 353 successively applies a backward thrust to the leafy vegetables, and the cut leafy vegetables are transported to the longitudinal conveying mechanism 32 in batches, and the relative speed between the longitudinal conveying mechanism 32 and the reed rod 353 is controlled to realize the batch transportation of the leafy vegetables. When the longitudinal conveying mechanism 32 is transporting the leafy vegetables backward, the transverse conveying mechanism 33 starts to work and pushes the leafy vegetables into the collection box 342 located on one side of the frame 31. After the collection box 342 is full, it can be replaced with an empty box on the empty box bearing platform 37.

[0099] Compared with the leafy vegetable harvesting machinery of the prior art, the present invention can realize the two tasks of cutting and collecting containers in one operation through the leafy vegetable orderly conveying and collecting device 3, thereby improving the harvesting efficiency; compared with the prior art's supporting conveying and harvesting method, the orderly collection of leafy vegetables is achieved by coordinating the forward speed of the machine, the rotation speed of the weeding mechanism 35, the speed of the longitudinal conveying mechanism 32, and the speed of the transverse conveying mechanism 33, with a simple structure, low production cost, and high collection efficiency. Among them, the movement of each mechanism of the leafy vegetable orderly conveying and collecting device 3 is driven by a motor, and the relative movement between the various parts can be achieved by mechanical transmission. A weeding mechanism 35 is arranged at the front end, which can control the rotation speed of the weeding rod 353 according to the forward speed, and send the leafy vegetables into the longitudinal conveying mechanism 32; the longitudinal conveying and the transverse conveying are combined, and in the longitudinal conveying process of the leafy vegetable harvesting, the leafy vegetables are pushed to the leafy vegetable collecting mechanism 34 on the side through the transverse conveying mechanism 33; based on the change of the motion relationship during the leafy vegetable conveying process, according to the leafy vegetable conveying speed and the target conveying position, the pushing angle and pushing speed of the longitudinal conveying mechanism 32 and the transverse conveying mechanism 33 are controlled by calculation and experiment; according to the change of the machine operation speed, the pushing speed can be automatically changed to avoid the problem of leafy vegetable accumulation and untimely pushing; after the leafy vegetable collecting box 342 is full, the collecting box 342 can be conveniently replaced by manual means. In addition, the leafy vegetable orderly conveying and collecting device 3 can also be used in conjunction with a small self-propelled vegetable harvester. After the leafy vegetables are harvested by the self-propelled vegetable harvester, the leafy vegetables are collected into the collecting box 342 through the scraper during the transmission process, so that the cutting, conveying and collecting operations can be completed in one operation.

[0100] Of course, the present invention may have many other embodiments.
