Description

Technical Field

[0001] The utility model relates to the technical field of pepper harvesting equipment, in particular to a self-propelled pepper harvester. Background Art

[0002] As an important crop, peppers are not only widely grown around the world but also loved for their rich nutritional value and unique flavor. To improve pepper harvesting efficiency, pepper harvesters have emerged as an important helper for farmers.

[0003] However, the existing pepper harvesters often have the following obvious disadvantages when in use: the existing pepper harvesters often directly transport the peppers to the cargo bin through a conveyor belt when in use, so when in use, it is often necessary to adjust the harvesting efficiency according to the capacity of the conveyor belt, and the harvesting efficiency is slow. Secondly, in the existing technology, if you want to increase the depth of the cargo bin, you need to extend the length of the conveyor belt at the same time, otherwise the conveying efficiency of the conveyor belt will be affected due to the excessive inclination angle.

At the same time, the lifting device can increase the depth of the cargo bin while the length of the self-propelled pepper harvester remains unchanged, further improving the harvesting efficiency and the amount of single harvest.

[0036] The walking assembly includes a driving mechanism 2 and a crawler mechanism. The driving mechanism 2 is used to drive the crawler mechanism to move, thereby driving the self-propelled pepper harvester to move.

[0037] The picking mechanism includes a C-frame 6, a transmission shaft 7, an active disc 8, an eccentric connecting rod 9, a driven disc 10, an eccentric guide ring 11, a comb square tube 12 and a rubber spring tooth 13. The C-frame 6 is fixedly connected to the conveyor belt 4 on the cutting platform. The C-frame 6 is used to install other parts of the picking mechanism. The C-frame 6 is provided with a roller cover 14. The roller cover 14 is provided with a slot corresponding to the rubber spring tooth 13. The roller cover 14 and the rubber spring tooth 13 cooperate with each other to separate the peppers and pepper stalks. The eccentric guide ring 11 is connected to the C-frame 6. The eccentric guide ring 11 is used to install the driven disc 10. The driven disc 10 is connected to the eccentric guide ring 1 1. Both ends of the transmission shaft 7 are connected to the C-frame 6. The transmission shaft 7 is used to drive the active disk 8 to rotate. The two ends of the eccentric connecting rod 9 are respectively connected to the active disk 8 and the driven disk 10. The driven disk 10 and the eccentric connecting rod 9 cooperate with each other to make the rubber elastic teeth 13 on the comb tooth square tube 12 always maintain a horizontal direction (that is, the same as the forward direction of the self-propelled pepper harvester) during use. Both ends of the comb tooth square tube 12 are connected to the eccentric connecting rod 9. A plurality of rubber elastic teeth 13 are provided on the comb tooth square tube 12. The rubber elastic teeth 13 are made of rubber material, so as to reduce the force when the pepper fruit and the rubber elastic teeth 13 contact each other.

[0038] The bottom of the C-frame 6 is equipped with a ground roller 15. This serves as a support structure for the header, effectively enhancing its operational stability and balance.

A baffle is provided at the bottom of the lifting frame 19 to prevent the peppers from falling to the ground. The lifting frame 19 is used to install other components of the lifting mechanism. The lifting gear 20 is externally connected to a motor (not shown). The lifting gear 20 is used to drive the chain 21 to move. Both sides of the hopper 22 are fixedly connected to the chain 21 so that it can move with the chain 21.

[0043] The crawler mechanisms are symmetrically arranged on both sides of the frame 1. The second drive mechanism includes an engine 23 and a gearbox 24. The gearbox is used to transmit the power generated by the generator to the drive wheel 26 in a certain proportion, thereby driving the crawler 25 to rotate. The power generated by the engine 23 is transmitted to the input shaft of the gearbox 24 through the crankshaft. The gearbox 24 then transmits the power to the crawler mechanism through the engagement and conversion of internal gears.

[0044] The track mechanism includes a track 25, a driving wheel 26, a supporting roller 27 and a tensioning wheel 28.

The driving wheel 26 is used to drive the track 25 to rotate. There are several supporting rollers 27, and several supporting rollers 27 are connected to the inner wall of the track 25. The supporting rollers 27 are mainly used to transfer the entire weight of the self-propelled pepper harvester to the ground. The stability and safety of the self-propelled pepper harvester are achieved by the rolling of the supporting rollers 27 on the internal guide rails (rail chain links) of the track 25. The track mechanism also includes a hydraulic oil tank for storing the hydraulic oil required for the operation of the track mechanism and a hydraulic oil heat sink for dissipating the hydraulic oil.

[0045] Working principle: When in use, the cutter driving motor 16 drives the transmission shaft 2 18 to move, thereby driving the transmission shaft 1 7 and the active disk 8 to rotate, and then drives the rubber spring teeth 13 to pick the peppers. The picked peppers will be transported by the cutter conveyor belt 4 to the lifting frame 19 for vertical transportation and transferred to the secondary conveyor belt 5. The secondary conveyor belt 5 will transport the peppers to the warehouse 3.

[0046] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
