[0077] The structural principle and working principle of the present application will be described in detail below in combination with the drawings:

[0078] Referring to Figure 1 and Figure 2 , Figure 1 is a structural schematic view of a leaf harvester according to an embodiment of the present application, Figure 2 is Figure 1 a side view. The leaf harvester of the present application comprises a traveling chassis 1, a cutting device 2, a leaf orderly conveying and collecting device 3 and a depth limiting wheel 4, wherein the traveling chassis 1, the cutting device 2 and the depth limiting wheel 4 are all installed or connected on a frame 31 of the leaf orderly conveying and collecting device 3, and the traveling chassis 1 comprises traveling wheels 11 and a chassis driving mechanism 12 connected with the traveling wheels 11. Since the composition, structure, mutual positional relationship, connection relationship and functions of other parts of the leaf harvester are all mature prior art, they will not be described here in detail, and only the leaf orderly conveying and collecting device 3 of the present application will be described in detail below.

[0079] Referring to Figures 3-5 , Figure 3 is a structural schematic view of a longitudinal conveying mechanism 32 according to an embodiment of the present application, Figure 4 is a structural schematic view of a transverse conveying mechanism 33 according to an embodiment of the present application, Figure 5Figure 1 is a schematic view of the installation angle of the transverse conveying mechanism 33 according to an embodiment of the present application. In this embodiment, the leafy vegetable orderly conveying and collecting device 3 comprises a frame 31, a longitudinal conveying mechanism 32 installed on the frame 31 for conveying the cut vegetables rearward, the longitudinal conveying mechanism 32 comprising a longitudinal driving motor 321, a driving roller 323, a driven roller 325 and a longitudinal conveying belt 324, the longitudinal driving motor 321 being connected to the driving roller 323 through a longitudinal shaft 322, the longitudinal conveying belt 324 being tensioned on the driving roller 323 and the driven roller 325, a transverse conveying mechanism 33 installed on the frame 31 and across the longitudinal conveying mechanism 32 for pushing the leafy vegetables on the longitudinal conveying mechanism 32 to the leafy vegetable collecting box 342 on the side, the transverse conveying mechanism 33 comprising a transverse driving motor 331, a transverse conveying belt 333, a conveying scraper 334, a driving roller 335 and a driven roller 336, the transverse driving motor 331 being connected to the driving roller 335 through a transverse shaft 332, the transverse conveying belt 333 being tensioned on the driving roller 335 and the driven roller 336, the conveying scraper 334 being installed on the transverse conveying belt 333 and being perpendicular to the movement direction of the transverse conveying belt 333 along the length direction, a leafy vegetable collecting mechanism 34 installed on the frame 31 and arranged on the side of the longitudinal conveying mechanism 32 corresponding to the transverse conveying mechanism 33 for carrying and assisting in replacing the leafy vegetable collecting box 342, and an operation control mechanism 36 arranged on the frame 31 and connected to the longitudinal conveying mechanism 32 and the transverse conveying mechanism 33 respectively.

[0080] In the embodiment, the transverse conveying mechanism 33 further comprises a scraper resetting member 337 arranged on the transverse conveying belt 333 and connected to the conveying scraper 334 to change the included angle between the plate surface of the conveying scraper 334 and the transverse conveying belt 333. The conveying direction of the transverse conveying belt 333 and the conveying direction of the longitudinal conveying belt 324 have an inclination angle to ensure that the leafy vegetables only have a transverse relative movement with the longitudinal conveying belt 324 during the pushing process of the conveying scraper 334. According to the rotating speed of the sweeping rod 353, the longitudinal driving motor 321 is controlled to rotate, thereby driving the longitudinal conveying belt 324 to start the operation and complete the longitudinal input of the leafy vegetables. The operation is performed during the rearward transportation of the leafy vegetables, and the transverse resistance is reduced under the premise of ensuring the longitudinal pushing force, and the longitudinal conveying belt 324 is preferably a straight stripe type conveying belt.

[0081] The main roller 335 is driven to rotate by the transverse driving motor 331, so that the transverse conveying belt 333 with the conveying scraper 334 is rotated, and the pipe plate is circulated. In order to avoid damage to the leaf vegetables during the conveying process caused by the rigid connection between the conveying scraper 334 and the transverse conveying belt 333, the conveying scraper 334 and the transverse conveying belt 333 are connected through the scraper reset member 337, which is preferably an elastic reset member 344. When the pressure exceeds a certain force, the angle between the conveying scraper 334 and the transverse conveying belt 333 can be changed, and when the resistance decreases, 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, and the two groups of transverse conveying mechanisms 33 work together to collect all the leaf vegetables in the longitudinal conveying mechanism 32 into the collection box 342. In order to reduce the damage to the leaf vegetables during the conveying process, the transverse conveying mechanism 33 and the longitudinal conveying mechanism 32 are installed at a certain angle, so that the leaf vegetables only have a transverse relative motion with the longitudinal conveying mechanism 32 during the conveying process. As shown in Figure 5 , 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, the angle between the y direction and the transverse conveying mechanism 33 is α, the speed of the longitudinal conveying belt 324 is v, and the conveying speed of the longitudinal conveying mechanism 32 is v / sinα.

[0082] Referring to Figure 6 , Figure 6The structure diagram of the raking mechanism 35 of an embodiment of the present application. The embodiment also comprises the raking mechanism 35, which is installed on the frame 31 and arranged in front of the longitudinal conveying mechanism 32, for supporting the stems to cooperate with the cutting knife to cut and timely push the cut crops onto the longitudinal conveying mechanism 32. According to the advancing speed, the rotating speed of the raking driving motor 351 is controlled, so that the leafy vegetables can be orderly fed into the longitudinal conveying mechanism 32 in batches under the pushing of the raking rods 353. The raking mechanism 35 comprises: two installation width plates 354, a plurality of raking rods 353 are evenly arranged between the two installation width plates 354, the raking rods 353 are arranged at the edges of the installation width plates 354, and the axes of the raking rods 353 are parallel to the axes of the installation width plates 354; and a raking driving motor 351, which is connected with the installation width plates 354 through a driving shaft 355 and drives the installation width plates 354 to rotate through the driving shaft 355. Wherein, the raking mechanism 35 is connected with the frame 31 through a transverse connecting rod 356 and a longitudinal connecting rod 357, the two ends of the transverse connecting rod 356 are respectively connected with the frame 31 and the longitudinal connecting rod 357 through bolt fixing mode; the upper part of the longitudinal connecting rod 357 is connected with a motor installation plate 352, and the depth limiting wheel 4 is installed at the bottom end of the longitudinal connecting rod 357; the raking driving motor 351 is installed on the motor installation plate 352, the motor installation plate 352 is connected with the installation width plate 354 through a shaft to become an integral whole, the longitudinal connecting rod 357 passes through the motor installation plate 352 and is fixed by jacking bolts, so as to realize the installation of the frame 31, the depth limiting wheel 4 and the raking mechanism 35. Through the cooperation of the raking rods 353, the longitudinal conveying mechanism 32 and the transverse conveying mechanism 33, the transverse pushing force is applied to the leafy vegetables in the process of feeding them in batches longitudinally, so as to feed them into the lateral collecting box 342 of the harvester.

[0083] The rotating speed of the raking rod 353 is controlled by the raking driving motor 351 according to the advancing speed of the machine tool, which can be changed in real time, and the speed is calculated in the following way:

[0084] The distance of the machine tool advancing per one equal part of the rotation of the raking rod 353 is:

[0085] S = V m 60 / mn;

[0086] Wherein, S is the distance of the machine tool advancing per one equal part of the rotation of the raking rod 353; V m is the advancing speed of the machine tool, with the unit of m / s; n is the rotating speed of the raking rod 353, with the unit of r / min; and m is the equal part number of the raking rod 353. The installation width plate 354 in the embodiment is a regular pentagon, and one raking rod 353 is installed at the center of each side, that is, the raking rod 353 is divided into 5 equal parts.

[0087] Wherein, the raking speed ratio: λ = V y / V m; wherein, V y is the circumferential velocity, V m is the forward speed of the machine.

[0088] When different λ values are taken, the trajectory of the sweeping rod 353 will be different, when λ = 0, it is a straight line, λ = 1 is a cycloid, λ < 1 is a short cycloid, and λ > 1 is a residual cycloid. Only when the trajectory of the sweeping rod 353 is a residual cycloid, the sweeping rod 353 will have a backward pushing force on the seedlings. Therefore, the sweeping speed ratio should be greater than 1.

[0089] The sweeping speed ratio is a necessary condition for determining the rotating speed of the sweeping rod 353. Increasing the sweeping speed ratio will increase the range of action and the degree of operation of the sweeping rod 353. When the forward speed of the machine is constant, the rotating speed of the sweeping rod 353 needs to be increased to increase the sweeping speed ratio. In order to avoid damage to the leafy vegetables, the rotating speed of the sweeping rod 353 should not be too fast.

[0090] According to the properties of the target vegetables, the appropriate sweeping speed ratio is selected. According to the sweeping speed ratio and the forward speed of the machine, the rotating speed of the sweeping rod 353 can be obtained:

[0091]

[0092]

[0093]

[0094] wherein, n is the rotating speed of the sweeping rod 353, the unit is r / min; D is the diameter of the sweeping wheel formed by the sweeping rod 353 and the installation width plate 354, the unit is m; V m is the left side speed of the machine, the unit is m / s; λ is the sweeping speed ratio.

[0095] The longitudinal conveying mechanism 32 of the embodiment conveys the cut leafy vegetables to the rear, and cooperates with the sweeping mechanism 35 to transport the leafy vegetables in layers during the conveying process. Therefore, the movement speed needs to match the movement speed of the sweeping rod 353. If the speed is lower than the speed of the sweeping rod 353, the leafy vegetables will be pushed twice and overlap, which is not conducive to subsequent orderly collection. If the speed is higher than the speed of the sweeping rod 353, the same batch of vegetables will be dispersed. Therefore, the speed of the longitudinal conveying belt 324 is the same as the speed of the sweeping rod 353.

[0096] Referring to Figure 7 , Figure 7The structure schematic diagram of the empty box carrying table 37 of an embodiment of the present application. The embodiment also comprises the empty box carrying table 37 arranged behind the longitudinal conveying mechanism 32, which comprises the support 372 connected with the rack 31 and the empty box placing table 371 installed on the support 372. The operation control mechanism 36 comprises the control console 362 arranged on the rack extended by the empty box carrying table 37 and the handrail 361 installed on the support 372. The control console 362 is connected with the longitudinal driving motor 321, the transverse driving motor 331 and the reaping driving motor 351 respectively. The handrail 361 and the empty box placing table 371 are arranged to facilitate the operation control and the placement of the empty collecting box 342 and the control console 362.

[0097] Referring to Figure 8 , Figure 8 The structure schematic diagram of the leaf collecting mechanism 34 of an embodiment of the present application. The leaf collecting mechanism 34 of the embodiment comprises the collecting rack 341 installed on one side of the rack 31, the collecting box 342 placed in the collecting rack 341, the limiting rod 343 installed at the front end of the collecting rack 341, the bottom of the limiting rod 343 provided with the hook for hooking the front end of the collecting box 342, which can limit the collecting box 342 in the limited position until the rear end of the collecting box 342 falls off the collecting rack 341, and the reset member 344 connected with the collecting rack 341 and the limiting rod 343 respectively for resetting the limiting rod 343, which is preferably the reset spring. Since the part of the transverse conveying mechanism 33 close to the cutting device 2 is operated first, it can ensure that the corresponding lower collecting box 342 is filled first. After the collecting box 342 is filled, the new collecting box 342 is replaced. The lower collecting box 342 moves forward under the pushing action of the rear collecting box 342. To avoid the collecting box 342 falling directly and contacting the ground first, which can cause the leaf in the collecting box 342 to scatter, the limiting rod 343 hooks the upper part of the collecting box 342 until the rear end falls off the bearing plate of the bottom side rack 31. Then the collecting box 342 falls off. 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 tool moves forward, it can ensure that the leaf in the collecting box 342 will not scatter.

[0098] In operation, after starting the harvester, the forward speed of the machine is controlled by adjusting the button. During operation, the machine advances, 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 prong driving motor 351 according to the forward speed of the machine, so as to drive the prong rods 353 to rotate clockwise at a suitable speed, each prong rod 353 applies a backward thrust to the leafy vegetables in turn, and the cut leafy vegetables are batched and delivered to the longitudinal delivery mechanism 32, and the relative speed of the longitudinal delivery mechanism 32 and the prong rods 353 is controlled to realize batched delivery of the leafy vegetables. During the backward delivery of the leafy vegetables by the longitudinal delivery mechanism 32, the transverse delivery mechanism 33 starts to work, and the leafy vegetables are pushed into the collection box 342 located on one side of the frame 31, and after the collection box 342 is filled, the empty collection box on the empty box carrying table 37 is replaced.

[0099] Compared with the prior art leafy vegetable harvesting machine, the leafy vegetable ordered delivery and collection device 3 can realize cutting and collection in one operation, and the harvesting efficiency is improved. Compared with the prior art holding type delivery and harvesting method, the leafy vegetables are orderly collected by coordinating the forward speed of the machine, the rotation speed of the prong mechanism 35, the speed of the longitudinal delivery mechanism 32, and the speed of the transverse delivery mechanism 33, the structure is simple, the production cost is low, and the collection efficiency is high. The movement of each mechanism of the leafy vegetable ordered delivery and collection device 3 is driven by a motor, and the relative movement between each part can be realized by mechanical transmission. The prong mechanism 35 is arranged at the front end, the rotation speed of the prong rods 353 is controlled according to the forward speed, and the leafy vegetables are delivered into the longitudinal delivery mechanism 32. The longitudinal delivery and the transverse delivery are combined, the leafy vegetables are pushed into the lateral leafy vegetable collection mechanism 34 by the transverse delivery mechanism 33 during the longitudinal delivery of the leafy vegetables; based on the change of the movement relationship during the delivery of the leafy vegetables, the pushing angle and the pushing speed of the longitudinal delivery mechanism 32 and the transverse delivery mechanism 33 are controlled according to the delivery speed and the target delivery position of the leafy vegetables; according to the change of the operation speed of the machine, the pushing speed can be automatically changed to avoid the problems of leafy vegetable accumulation and untimely pushing; after the leafy vegetable collection box 342 is filled, the collection box 342 can be conveniently replaced by manual replacement. In addition, the leafy vegetable ordered delivery and collection device 3 can also be used in cooperation with a small self-propelled vegetable harvester. After the leafy vegetables are harvested by the self-propelled vegetable harvester, the leafy vegetables are delivered and collected into the collection box 342 by the scraper during the transmission process, and the cutting, delivery and collection operations can be completed in one operation.
