Detailed ways

The tobacco harvester shown in Figures 1 to 3 includes a vehicle frame and a vehicle part. The vehicle frame includes a main frame top plate 8, a left bottom leaf box baffle 13 and a right bottom leaf box baffle 2. The main frame The top plate 8 is connected with the bottom leaf box baffle plate 13 and the right bottom leaf box baffle plate 2 through several vehicle frame frames. Engine 7 and tobacco leaf collection box 26 are housed on the main frame top plate 8, left main conveyer belt 25 is housed between left side bottom leaf box baffle plate 13 and tobacco leaf collection box 26, right bottom leaf box baffle plate 2 and tobacco leaf collection The right side main conveyor belt 22 is housed between the case 26, the left side main conveyor belt 25, the right side main conveyor belt 22, the middle part main conveyor belt 23 link to each other with the engine 7 by the conveyor belt input system 21. The vehicle frame is divided into three groups of the left side, the middle part and the right side, and each group is distinguished from the front and back, the inner and outer sides or the left and right sides. 15. Between the middle front left frame frame 9 and the middle front right frame frame 6, a middle bottom conveyor belt 17 is installed, and between the right front inner frame frame 5 and the right front outer frame frame 3, a right bottom conveyor belt 19 is installed . The left bottom conveyor belt 15 , the middle bottom conveyor belt 17 and the right bottom conveyor belt 19 are also connected to the engine 7 by a conveyor belt input system 21 . the

As shown in Fig. 6 and Fig. 7, there are box top vertical bar 34, box left cross bar 35 and box right side cross bar 35 ' on the tobacco leaf harvesting cutter box, motor 30 is housed in the tobacco leaf harvesting knife box, motor main shaft 31 Link to each other with cam supporting shaft 37 by coupling 36, left cam 32 and right cam 32 ' are housed on cam supporting shaft 37, also comprise left swing driven lever 33 and right swing driven lever 33 ', left swing driven lever 33 Contact with the left cam 32, and the left swing driven rod 33 is connected with one end of the flexible cutter head 16; Connected, the flexible cutter head 16 is a roller made of elastic material, and the elastic material can be rubber or plastic or other. the

The tobacco leaf harvesting knife box is divided into the left outer tobacco leaf harvesting knife box 11, the left inner tobacco leaf harvesting knife box 11', the right outer tobacco leaf harvesting knife box 4 and the right inner tobacco leaf harvesting knife box 4', as shown in Figures 4-5 As shown, the main frame roof 8 is equipped with a hanger 28 on the harvesting box, and the box top vertical rod of the left outer tobacco leaf harvesting knife box 11 is fixed on the upper hanger 28 of the harvesting box by bolts 28 ′. Bar 35 is fixed in the fixed groove on the left rear outer frame frame 24 by bolt, and box right cross bar 35 ' is fixed in the fixed groove 10 ' on the left front outer frame frame 10. The left inner tobacco leaf harvesting knife box 11' is installed between the middle front left side frame frame 9 and the middle rear left side frame frame in the same connection mode, and the right outer side tobacco leaf harvesting knife box 4 is installed on the right front inner side frame frame 5 and between the right rear inner side frame frame, the right inner side tobacco leaf harvesting cutter box 4 ' is contained between the middle front right side frame frame 6 and the middle rear right side side frame frame. the

Described driving system comprises front-wheel steering system 20, engine, and four wheels, and wherein front-wheel steering system 20 controls the advancing direction of right front wheel 1 and left front wheel 14, and right rear wheel 14 ' and left rear wheel are driven by engine. drive. the

The working mode of the present utility model is illustrated by taking the left outer tobacco leaf harvesting cutter box 11 as an example: after the motor 30 is started, the rotation of the motor main shaft 31 is transmitted to the coaxially consolidated left cam 32 and right cam 32′ through the shaft coupling 36 , the left swing driven rod 33 and the right swing driven rod 33′ reciprocate up and down, and the tobacco leaf is broken from the stem through the flexible cutter head 16, and the tobacco leaf at the broken stem falls to the bottom under the action of the beating force acting downward Leaf box, and send it into the right main conveyor belt 22, the central main conveyor belt 23, the left main conveyor belt 25 by the left bottom conveyor belt 15, the middle bottom conveyor belt 17, and the right bottom conveyor belt 19, and finally send it into the tobacco leaf collecting box 26 . the

Because the contact area between the flexible cutter head 16 and the tobacco leaves is relatively large, the stress acting on the unit area of the tobacco leaves is relatively small. Therefore, when the flexible cutter head 16 is slapped, it can cut off the mature leaf stem from the root without damaging the tobacco leaves. foliage. the

The average height of tobacco is about 1.5m, and the height of the main frame top plate 8 of the tobacco harvester exceeds the average height of tobacco. As shown in Figure 3, when the harvester is walking forward, the right front inner side frame frame 5 and the middle front right side frame frame 6 points across the left and right sides of the right ridge tobacco rod 29', while the left front inner side frame frame 10, 9 points in the front left side of the vehicle frame frame straddle the left and right sides of the left ridge tobacco rod 29. The flexible cutter head protruding from the harvesting knife box reciprocates up and down to slap the tobacco leaves on the tobacco rods 29, 29', causing the tobacco leaves to break from the stalks, and under the action of the downward slapping force, fall into the tobacco leaves on the stems respectively. In the bottom leaf boxes of left, middle and right positions, the tobacco leaves are sent to the main conveyor belt respectively by the bottom conveyor belt at the bottom of the bottom leaf box, and finally sent into the tobacco leaf collection box 26 on the top. the

Since the tobacco matures from the bottom to the top, the first layer of tobacco leaves at the bottom is harvested for the first time, and after a period of time, the second and third layers are harvested at different times according to the maturity, and the upper layer is gradually harvested. receive. By putting the left and right crossbars of the harvesting box into different fixing grooves on the vehicle frame, the position of the harvesting box can be changed from bottom to top. the

The engine 7 is a diesel engine with a generator. the
