[0030] To enable those skilled in the art of this technology to better understand the solution of the present invention, the following will further elaborate on the present invention in combination with the drawings and specific implementation manners.

[0031] Refer to Figures 1 to 3 , Figure 1 Structural schematic diagram of the tomato harvesting machine's seedling supporting device provided by the present invention; Figure 2 For Figure 1 Side view when the tomato feeding amount is large in Figure 3 For Figure 1 Side view when the tomato feeding amount is small in

[0032] The present invention provides a tomato seedling supporting device for a tomato harvester, which mainly includes a frame 2, a driving wheel assembly 3, a seedling supporting conveyor belt 4 and an oil cylinder 1.

[0033] The frame 2 is provided with a mounting frame, a hinge shaft 21, a pair of steering wheels 22, two bearing mounting plates 25, two oil cylinder force arms 26 and a pair of tension wheels 27. The hinge shaft 21 is rotatably installed on the cutting table. The mounting frame is vertically installed at the front of the hinge shaft 21. A pair of steering wheels 22 are installed at the rear of the hinge shaft 21. Two bearing mounting plates 25 are arranged on the front end face of the mounting frame. One oil cylinder force arm 26 and one tension wheel 27 are respectively arranged on the two outer sides of the mounting frame. The two tension wheels 27 press against the upper surface of the seedling supporting conveyor belt 4 to provide a tension force to the seedling supporting conveyor belt 4.

[0034] Reference Figure 4 , Figure 4 For Figure 1 the structural schematic diagrams of the driving wheel, hydraulic motor and speed reducer in

[0035] The driving wheel assembly 3 is provided with a driving shaft 31. Driving wheels 32 and bearings 33 are installed at both ends of the driving shaft 31. A driving device for driving the driving shaft 31 and the driving wheels 32 to rotate is installed on the driving shaft 31. Material seedling supporting conveyor belts 34 for assisting in material conveyance are respectively arranged on the outer side end faces of the two driving wheels 32. A plurality of tooth segments 321 for dialing the seedling supporting conveyor belt and distributed circumferentially are arranged on the inner side faces of the two driving wheels 32. Preferably, the tooth segments 321 are circumferentially and evenly distributed on the inner circumferential surface of the driving wheel 32 to realize the smooth conveyance of the seedling supporting conveyor belt 4.

[0036] The front end of the seedling supporting conveyor belt 4 is sleeved on the driving wheel assembly 3, and the rear end of the seedling supporting conveyor belt 4 is sleeved on the steering wheel 22. A plurality of seedling supporting fingers 43 are installed on the outer peripheral surface of the seedling supporting conveyor belt 4. When the driving wheel assembly 3 rotates, the tooth segments 321 dial the belt steel bars of the seedling supporting conveyor belt 4 to run.

[0037] The lower hinge point of the oil cylinder 1 is fixed on the cutting table, and the waist-shaped hole at the telescopic end of the oil cylinder 1 is slidably hinged to the oil cylinder force arm 26 to adjust the feeding amount of tomato fruit seedlings.

[0038] Specifically, the driving device drives the driving shaft 31 to rotate, and the driving shaft 31 drives the driving wheels 32 to rotate. Material seedling supporting conveyor belts 34 are installed on the driving wheels 32, which can assist in material conveyance. The entire driving wheel 32 is installed on the mounting frame through bearings 33. When the driving wheel 32 rotates, the tooth segments 321 thereon drive the seedling supporting conveyor belt 4 to rotate clockwise.

[0039] The hinge shaft 21 is hingedly installed inside the cutting table and is arranged above the cutting table conveyor belt. The lower hinge point of the oil cylinder 1 is fixed on the cutting table, and one end is hinged to the oil cylinder force arm 26 through a waist-shaped hole. The telescopic movement of the oil cylinder 1 can adapt to different feeding amounts of materials. As Figure 2and Figure 3 As shown. When the oil cylinder 1 extends, the hinge shaft 21 remains stationary and becomes the hinge point. The entire seedling-holding device rotates upward around the mounting base, and the distance between the seedling-holding conveyor belt 4 and the header conveyor belt increases, as Figure 2 shown. More tomato fruit seedlings can pass through, and the harvesting rate of tomato fruit seedlings can be increased.

[0040] When the extension of the oil cylinder 1 is not adjusted but the number of tomato fruit seedlings increases, the waist-shaped hole at the connection between the oil cylinder 1 and the oil cylinder lever arm 26 plays a buffering and adjusting role. The acting force of the tomato causes the seedling-holding device to lift upward, as Figure 2 shown. The distance between the seedling-holding conveyor belt 4 and the header conveyor belt increases, more tomato fruit seedlings can pass through, and tomato fruit seedling blockage or tomato fruit damage can be avoided.

[0041] When the tomato fruit seedlings are sparse, the extension of the oil cylinder 1 can be appropriately adjusted to ensure the harvesting efficiency, as Figure 3 shown.

[0042] The seedling-holding conveyor belt 4 is placed directly above the header conveyor belt, as Figure 2 shown. At this time, the header conveyor belt moves in the same direction as the upper conveyor belt, and the fruit seedlings of the tomato pass through the middle of the seedling-holding conveyor belt 4 and the header conveyor belt and are conveyed backward. Driven by the seedling-holding device, the overall conveying efficiency is improved.

[0043] In this application, by installing seedling-holding fingers 43 on the seedling-holding conveyor belt 4 of the seedling-holding device of the tomato harvester, the seedling-holding function can be achieved, the harvesting efficiency of tomatoes can be improved, and the loss of tomatoes can be reduced. In addition, the seedling-holding device is equipped with an oil cylinder 1, which can actively adjust the height of the seedling-holding device to adapt to different feeding amounts, and the waist-shaped hole at the connection of the oil cylinder 1 also plays a buffering and adjusting role.

[0044] Since most of the materials of the existing seedling-holding fingers 43 of tomato harvesters are metal materials, they will cause damage to tomato fruits and result in a high tomato breakage rate. To improve this problem, the seedling-holding fingers 43 in this application are preferably made of rubber fingers, which can effectively ensure that the fruits are not damaged while playing an auxiliary conveying role. The material seedling-holding conveyor belt 34 is installed on the end face of the driving wheel 32 through a connecting piece and a bolt locking piece, and a conveying channel is formed between the two material seedling-holding conveyor belts 34 to facilitate auxiliary material conveying.

[0045] Specifically, the driving device includes a hydraulic motor 5 and a reduction box 6. The hydraulic motor 5 drives the seedling-holding conveyor belt 4 to rotate forward for seedling-holding through the reduction box 6. In addition, the seedling-holding device also has a reverse cleaning and blocking function. When the header is blocked, the hydraulic motor can reverse, drive the seedling-holding conveyor belt 4 to reverse through the reduction box 6, and the seedling-holding fingers 43 on the seedling-holding conveyor belt 4 will pick out the tomato fruit seedlings from the header conveyor belt.

[0046] Please refer to Figure 6 ,Figure 6 is Figure 1 a schematic structural diagram of the middle frame.

[0047] The mounting frame of the frame includes two mounting rods 23 perpendicular to the hinge shaft 21 and a connecting frame 24 vertically mounted between two bearing mounting plates 25. Bearing mounting plates 25 are provided on the front end faces of the two mounting rods 23, and each connecting structure is welded or detachably connected by bolts.

[0048] Refer to Figure 5 , Figure 5 is Figure 1 a schematic structural diagram of the tomato seedling supporting conveyor belt in

[0049] The tomato seedling supporting conveyor belt 4 includes at least two parallel annular belts 41, several groups of steel bars 42 for connecting adjacent belts 41, and several steel bars for mounting the tomato seedling supporting fingers 43 and installed on each steel bar 42. The steel bars 42 are riveted on the tomato seedling supporting conveyor belt 4, the steel bars are installed on the steel bars 42, and the tomato seedling supporting fingers 43 are installed on the steel bars. The tomato seedling supporting fingers 43 are installed at an angle with the tomato seedling supporting conveyor belt 4 to avoid damaging the tomato fruits during the conveying process of the tomato fruit seedlings.

[0050] Preferably, the installation angle between the tomato seedling supporting fingers 43 and the vertical plane of the material tomato seedling supporting conveyor belt 34 is 45° - 60°

[0051] In order to improve the accuracy and stability of the operation of the tomato seedling supporting conveyor belt 4, at least two rollers can be installed on the outer sides of the two mounting rods 23. The rollers play a role in supporting and guiding the tomato seedling supporting conveyor belt 4, and can ensure the accurate, efficient and stable transmission of the tomato seedling supporting conveyor belt 4.

[0052] In summary, the tomato fruit seedlings are conveyed backward under the combined action of the cutting table conveyor belt and the tomato seedling supporting device, thereby improving the conveying efficiency. The tomato seedling supporting fingers 43 are installed on the steel bars 42 of the tomato seedling supporting device, and the tomato seedling supporting fingers 43 are installed at an angle relative to the tomato seedling supporting conveyor belt 4. During the rotation of the conveyor belt of the tomato seedling supporting device, the tomato seedling supporting fingers 43 can send the tomato fruit seedlings backward. Since the tomato seedling supporting fingers 43 have appropriate hardness and can bend appropriately, and the rotation speed of the conveyor belt is appropriate, the damage rate to the tomato fruits is reduced. When the cutting table is blocked, the tomato seedling supporting device reverses to send the tomato fruit seedlings outwards to clean the blocked tomato fruit seedlings. In addition, the tomato seedling supporting device in this application is installed above the cutting table conveyor belt, and the conveying height of the entire tomato seedling supporting device relative to the cutting table is adjustable. The height of the tomato seedling supporting device is adjusted according to the feeding amount, so that the tomato seedling supporting device has better adaptability to the feeding amount of the tomato fruit seedlings and improves the production efficiency.

[0053] This application effectively solves the technical problems in the existing tomato harvester's seedling supporting device, such as the poor effect of the efficient auxiliary conveying of the cutting table, being unsuitable for high-speed tomato harvesting operations, and being unable to automatically adjust the seedling supporting device according to different feeding amounts, effectively improving the production efficiency of lodging crops.

[0054] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention.
