[0048] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0049] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] Combination Figures 1 to 10 As shown, the utility model proposes an all-in-one lettuce harvesting and baling machine, which can complete a series of operations such as defoliation, harvesting and baling of lettuce, thereby improving the efficiency of lettuce harvesting and saving certain labor costs.

[0051] Combination Figures 1 to 5 As shown, the lettuce harvesting and baling machine of the utility model includes structural components such as a machine body, a harvesting and leaf removing mechanism 1, a transmission mechanism 2, a baling mechanism 3 and a crawler-type traveling mechanism 4.

[0052] Combination Figure 6 and Figure 7 As shown, the front end of the machine body is provided with a plurality of harvesting and leafing mechanisms 1, which are used to complete operations such as straightening, leafing and harvesting of lettuce. Each harvesting and leafing mechanism 1 includes a harvesting shell 11, a leafing drum 12 and a disc blade 13.

[0053] Combination Figure 7 As shown, the harvesting shell 11 includes a base plate 111, a T-shaped bracket 112 and a straightening block 113. The straightening block 113 is fixedly connected to the T-shaped bracket 112 and is arranged on the base plate 111. The straightening block 113 is arranged at the front end of the T-shaped bracket 112, and is also located at the front end of the entire lettuce harvesting and baling machine. The outer contour of the straightening block 113 is in the shape of an oblique triangular prism, and there is a gap between adjacent straightening blocks 113 to facilitate the passage of lettuce. During the movement of the machine body, the lettuce can be gathered and straightened by the inclined surfaces of adjacent straightening blocks 113. The straightening block 113 can adjust the posture of the lettuce plant to ensure that it is in an upright state, and ensure that each lettuce can accurately enter the preset defoliation area, creating favorable conditions for subsequent defoliation and harvesting steps. The lettuce enters the defoliation area surrounded by adjacent T-shaped brackets 112 through the gap between adjacent straightening blocks 113 for defoliation.

[0054] Combination Figure 4 and Figure 7 As shown, the leaf removing rollers 12 are arranged on both sides of the T-shaped bracket 112, wherein two groups of leaf removing rollers 12 are arranged on each side of the T-shaped bracket 112, and each group of leaf removing rollers 12 is arranged at an angle. The leaf removing rollers 12 include two groups of upper and lower circular mounting plates, a main shaft, and a plurality of rigid optical shafts arranged between the mounting plates, wherein the main shaft passes through the center of the upper and lower groups of circular mounting plates, and one end of the main shaft is fixedly connected to the output shaft of the motor, and the main shaft and the plurality of rigid optical shafts are at an angle of 45° to the plane. The motor drives the main shaft to rotate and simultaneously drives the plurality of rigid optical shafts to rotate, and the plurality of rigid optical shafts rotate at high speed, and the waste leaves of the lettuce are quickly broken up by the strong centrifugal force to complete the leaf removing operation.

[0055] The leaf removing roller 12 reduces the degree of damage to the lettuce stem during the leaf removing operation, can better preserve the integrity of the stem, and improve the market value of the lettuce. At the same time, it can better adapt to the shape and arrangement of the leaves, more effectively separate the leaves from the stem, improve the leaf removing efficiency, and save the cost of manual leaf removing.

[0056] Combination Figure 3 and Figure 6 As shown, the disc blade 13 is arranged at the bottom of the bottom plate 111, and the circumferential edge of the disc blade 13 is serrated. In view of the brittle and hard characteristics of lettuce, the serrated disc blade 13 is selected as the harvesting tool. The disc blade 13 is designed to achieve precision and neatness during cutting, reducing unnecessary damage and waste. At the same time, the serrated structure also helps to improve cutting efficiency, making the entire harvesting process faster and more efficient.

[0057] The leaf removing roller 12 and the disc blade 13 are both made of alloy steel, which has high hardness, high strength, long-lasting durability and reliability, and the coating has strong toughness.

[0058] Combination Figure 2 and Figure 4 As shown, the rear side of the T-shaped bracket 112 is connected to the transmission mechanism 2, and the lettuce processed by the harvesting and leaf removal mechanism 1 is transported by the transmission mechanism 2 and conveyed to the rear end of the machine body.

[0059] Combination Figure 2 and Figure 4 As shown, the transmission mechanism 2 includes a bottom conveying shell 20 , an auxiliary conveying belt 21 , a main conveying belt 22 and a top conveying shell 23 .

[0060] Combination Figure 2 and Figure 4As shown, the bottom conveying shell 20 is arranged on the rear side of the T-shaped bracket 112, and is used to receive the lettuce after leaf removal and harvesting, wherein the front side of the bottom conveying shell 20 is open, and the lettuce after leaf removal and harvesting enters into the bottom conveying shell 20 through the gap between adjacent T-shaped brackets 112.

[0061] Combination Figure 2 and Figure 4 As shown, there are two sets of auxiliary conveyor belts 21, which are symmetrically arranged at the two ends of the rear side of the bottom conveyor shell 20, and the two sets of auxiliary conveyor belts 21 are both arranged vertically, and a plurality of convergence push plates are fixedly arranged on the auxiliary conveyor belts 21. The convergence push plates arranged on the auxiliary conveyor belts 21 can push and converge the lettuces on both sides to the middle of the bottom conveyor shell 20, so that the lettuces can slide onto the main conveyor belt 22.

[0062] Combination Figure 1 and Figure 2 As shown, the main conveyor belt 22 is arranged at an angle, and one end of the bottom of the main conveyor belt 22 is connected to the middle position of the rear side of the bottom conveyor shell 20, and is located between the two sets of auxiliary conveyor belts 21. A plurality of conveying baffles are provided on the main conveyor belt 22 to prevent the lettuce from rolling down due to the tilt, thereby ensuring the smooth transportation of the lettuce. One end of the top of the main conveyor belt 22 is connected to one end of the top conveyor shell 23, and the other end of the top conveyor shell 23 is connected to the top opening of the temporary storage box 31. The top conveyor shell 23 is used to ensure that the lettuce transported by the main conveyor belt 22 smoothly enters the temporary storage box 31 for bundling processing, prevents it from falling due to the shaking of the machine body, and ensures the smooth progress of subsequent processing.

[0063] Combination Figure 2 and Figure 4 As shown, a rotating shaft is arranged inside the top conveying shell 23, and two sorting wheels 24 are arranged on the rotating shaft, and the rotating shaft is driven by a reduction motor. The sorting wheel 24 is arranged with five teeth and can rotate with the rotating shaft. Since the root of the lettuce is thicker and the head is thinner, when the lettuce passes through the sorting wheel 24 on the same horizontal line, the thicker part of the root will be blocked, while the thinner part of the head will not be blocked, so the lettuces facing different directions will slide to the opposite direction, and finally the lettuces sliding to the same end of the temporary storage box 31 can all face the same direction, which is convenient for subsequent bundling operations.

[0064] Combination Figure 1 , Figure 2 and Figure 4 As shown, a temporary storage box 31 is horizontally arranged at the rear end of the machine body, and the temporary storage box 31 can store lettuce. The top middle and both ends of the temporary storage box 31 are opened, and the other end of the top conveying shell 23 is connected to the top opening of the temporary storage box 31. After being conveyed by the main conveyor belt 22 and screened by the sorting wheel 24, the lettuce enters the interior of the temporary storage box 31 through the opening.

[0065] Combination Figure 8 As shown, two rows of sorting rollers 32 are arranged inside the temporary storage box 31 and just below the top opening, and the two rows of sorting rollers 32 are arranged at an angle. The sorting rollers 32 are in a "pyramid" shape as a whole, and the height of the sorting rollers 32 near the middle of the temporary storage box 31 is higher, and the height of the sorting rollers 32 near the two ends of the temporary storage box 31 gradually decreases, and the sorting rollers 32 near the two ends of the temporary storage box 31 do not contact the bottom plate of the temporary storage box 31.

[0066] Combination Figure 8 As shown, a photoelectric sensor is arranged inside the temporary storage box 31 , and the photoelectric sensor is used to detect the height of the lettuce in the temporary storage box 31 .

[0067] A longitudinal baffle 331 is arranged inside the temporary storage box 31 and obliquely above the sorting roller 32 near the end of the temporary storage box 31. The longitudinal baffle 331 is fixedly connected to the slider of the first electric lead screw. The first electric lead screw is arranged vertically, and the longitudinal baffle can move longitudinally along the slide rail of the first electric lead screw. When the photoelectric sensor can detect the storage height of the lettuce, once the preset height is reached, the longitudinal baffle 331 will drop rapidly driven by the first electric lead screw, effectively preventing the subsequent lettuce from sliding onto the bottom plate of the temporary storage box 31.

[0068] A transverse push plate 332 is arranged inside the temporary storage box 31 and obliquely below the sorting roller 32. At the same time, at the initial moment, the transverse push plate 332 is arranged below the longitudinal baffle 331. The transverse push plate 332 is fixedly connected to the slider of the second electric lead screw, and the second electric lead screw is arranged horizontally. The transverse push plate 332 can move laterally along the slide rail of the second linear guide rail. Driven by the second electric lead screw, the transverse push plate 332 can push the lettuce falling on the bottom plate of the temporary storage box 31 to the end opening of the temporary storage box 31, so that the baling mechanism can perform baling processing later.

[0069] Combination Fig. 9 and Fig.10 As shown, a group of baling mechanisms are respectively provided at the left and right ends of the temporary storage box 31 , and the baling mechanisms include a stepping motor 34 , a belt 35 , a baling disc 36 , a cylinder, a first cylinder push rod 381 , a second cylinder push rod 382 and an adhesive tape 37 .

[0070] The stepper motor 34 and the air pump are both arranged at the bottom of the temporary storage box 31, and the output shaft of the stepper motor 34 is connected to the baling disc 36 through the belt 35. The baling disc 36 is arranged at the end of the temporary storage box 31, and the middle of the baling disc 36 is open, and the lettuce can pass through the center of the baling disc 36. At the same time, the baling disc 36 is fixedly connected with the adhesive tape 37. The stepper motor 34 can accurately control the number of rotations, thereby ensuring the number of windings of the adhesive tape 37 and ensuring a firm bundling effect. The bottom of the temporary storage box 31 is provided with a first cylinder push rod 381 and a second cylinder push rod 382, ​​and the first cylinder push rod 381 and the second cylinder push rod 382 are connected to the cylinder through an air pipe and an air pump, wherein a blade is arranged at the end of the second cylinder push rod 382, ​​and the blade can cut the adhesive tape 37.

[0071] A controller is also provided on the machine body, and the controller is connected to components such as a photoelectric sensor, a first electric lead screw, a second electric lead screw, a stepper motor, a reduction motor and a cylinder through a signal cable to realize remote control of the lettuce harvesting and baling machine.

[0072] The bundling process of the utility model is as follows:

[0073] When baling is not performed, the end of the adhesive tape 37 is bonded to the first cylinder push rod 381; when baling is performed, the stepper motor 34 drives the baling disc 36 to rotate through the belt 35, and then the adhesive tape 37 rotates with the baling disc 36; after rotating one and a half circles, the first cylinder push rod 381 is pushed out, and the baling disc 36 continues to drive the adhesive tape 37 to rotate half a circle and then stops rotating. At this time, the second cylinder push rod 382 is pushed out and the adhesive tape 37 is cut by the blade set at the end; after cutting is completed, the first cylinder push rod 381 and the second cylinder push rod 382 are retracted. At this time, the end of the adhesive tape 37 continues to be bonded to the first cylinder push rod 382, ​​which is convenient for subsequent baling processing; when the cutting of the adhesive tape 37 is completed, the lateral push plate 332 pushes the bundled lettuce out of the temporary storage box 31.

[0074] Combination Figures 1 to 5 As shown, the utility model harvester and baler adopts a crawler-type travel mechanism, which includes a driving wheel, a driven wheel and an outer crawler, wherein the crawler can increase the contact area between the machine body and the ground, so that the machine body can work stably on soft or muddy ground, and at the same time can reduce damage to the ground, which is beneficial to protecting the working environment. In addition, the crawler is also provided with an anti-skid pattern, which can increase the firmness of the crawler and improve the adhesion between the crawler and the ground, ensure the stability of the travel process, and provide favorable conditions for lettuce harvesting and baling.

[0075] The utility model proposes a lettuce harvesting and baling integrated machine. By setting a harvesting and leafing mechanism 1 at the front end of the machine body, after the lettuce is straightened by the harvesting shell 11, the leafing roller 12 and the disc blade 13 remove the leaves and harvest the lettuce, saving the cost of manual leafing and improving the efficiency of harvesting. The lettuce is transported by setting a transmission mechanism 2, and a sorting wheel 24 is added to complete the preliminary sorting and screening of the lettuce, providing convenient conditions for subsequent baling. By setting a temporary storage box 31 at the rear end of the machine body, the storage of the lettuce is completed, and a baling mechanism is set at both ends of the temporary storage box 31 to complete the baling of the lettuce, improving the work efficiency and saving the cost of manual baling. The lettuce harvesting and baling integrated machine of the utility model can complete a series of process operations such as leafing, harvesting and baling of the lettuce. This set of process operations reduces the influence of human factors on the harvesting operation, thereby ensuring the quality of the lettuce and the uniformity of the harvesting. At the same time, the utility model has a simple structure and low later maintenance cost.
