Description

Technical Field

[0001] This utility model relates to an agricultural harvester, and more particularly to a chili harvester. Background Technology

[0002] Chili peppers have numerous processed products, a long industrial chain, and high added value, making them one of the main economic crops in many regions. With the development of technology, the process of agricultural mechanization is accelerating, and chili pepper harvesters, as a new type of agricultural machinery, can greatly improve the efficiency and yield of chili pepper cultivation.

[0003] Agricultural mechanization is an important indicator of agricultural modernization. The chili harvester market is developing rapidly, with product output continuously expanding. Investors are paying closer attention to the chili harvester market, making it increasingly popular among all parties.

[0004] Currently, there are no widely available and mature models of chili harvesters, and the level of agricultural mechanization is relatively low. Large harvesters are expensive, while small harvesters are not fully functional, only capable of harvesting chilies and lacking functions such as sorting, storage, and tilling. For example, after harvesting, sorting is required manually or by other machines, resulting in high labor costs and labor intensity. Utility Model Content

[0005] In view of this, it is necessary to provide a chili harvester that is compact in structure and can perform multiple functions such as harvesting, screening, storing, and crushing straw, thereby improving farmers' labor efficiency, reducing costs, and increasing profits.

[0006] A chili harvester includes a frame with walking modules on both sides for moving the harvester; a harvesting module at the front of the frame for peeling chilies from branches and collecting them to a conveying module; a conveying module at the end of the harvesting module for transporting the chilies to a screening module; a storage box in the middle of the frame with a screening module above it for separating chilies from debris and allowing the chilies to fall into the storage box; a crushing module at the bottom of the frame for cutting and crushing the harvested chili stalks; and a soil loosening module at the rear of the frame for turning the crushed stalks into the soil.

[0007] This chili harvester is compact and small in size, and is multifunctional, not only harvesting chilies but also integrating functions such as screening, storage, straw crushing, and soil turning. It operates quickly and efficiently, completing large-scale chili harvesting tasks in a short time, greatly improving harvesting efficiency and reducing the need for workers to change vehicles and transport materials, thus saving manpower. Each module can also work independently, allowing users to select the required function based on actual needs. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 and Figure 2 As shown, the chili harvester includes a frame 1, with walking modules 2 on both sides of the frame 1 for moving the chili harvester; a harvesting module 3 on the front of the frame 1 for peeling chilies from the branches and collecting them to a conveying module 4; a conveying module 4 at the end of the harvesting module 3 for conveying the chilies to a screening module 5; a storage box 6 in the middle of the frame 1, with a screening module 5 above the storage box 6 for separating chilies from debris and allowing the chilies to fall into the storage box 6; a crushing module 7 at the bottom of the frame 1 for cutting and crushing the harvested chili stalks; and a soil loosening module 8 at the rear of the frame 1 for turning the crushed stalks into the soil.

[0020] like Figure 3 As shown, the walking module 2 includes several walking motors 21. A first walking sprocket 22 is fixedly mounted on the output end of each walking motor 21. The first walking sprocket 22 meshes with a walking toothed chain 23. The walking toothed chain 23 simultaneously meshes with a second walking sprocket 24. The second walking sprocket 24 is fixedly connected to a pulley 25. A track 26 meshes with the surface of the pulley 25. In use, the walking motor 21 rotates the first walking sprocket 22, which transmits power to the second walking sprocket 24 and the pulley 25 via the walking toothed chain 23, thereby driving the track 26 to move, allowing the chili harvester to move forward or backward.

[0021] In this embodiment, the frame 1 has three walking motors 21 arranged on one side. The front and rear walking motors 21 are each matched with a first walking sprocket 22, a second walking sprocket 24, and a pulley 25. The middle walking motor 21 is matched with a first walking sprocket 22, two second walking sprockets 24, and two pulleys 25. The above four pulleys 25 are arranged horizontally to increase the ground contact area of ​​the track 26, improve traction, and enable the chili harvester to adapt to soft soil environments. Two unpowered driven pulleys 27 are also engaged on the inner side of the track 26. The driven pulleys 27 are located above the pulleys 25 to distribute the tension of the track 26 and extend its service life.

[0022] The walking module 2 also includes several non-powered auxiliary wheels 28, which are located inside the walking module 2. Without increasing the overall size of the harvester, the auxiliary wheels further ensure that the trolley can still walk stably in harsh environments, prevent the tracks 26 from slipping or the harvester from tipping over, and overcome the problem that ordinary harvesters cannot enter remote, muddy or other rugged terrain.

[0023] like Figure 4 and Figure 5 As shown, the harvesting module 3 includes a roller 31, the sidewall of which is composed of several parallel long rods 32. A harvesting plate 33 is provided below the roller 31, and a harvesting screw 34 is provided between the harvesting plate 33 and the roller 31. The surface of the harvesting screw 34 is provided with axially extending spiral ridges. Both the roller 31 and the harvesting screw 34 can rotate around their axes. A harvesting conveyor belt 35 is provided at the tail of the harvesting screw 34, and the harvesting conveyor belt 35 extends to the conveying module 4. In use, the roller 31 rotates, and the rotation of the long rods 32 breaks off branches or knocks the peppers off the branches and rolls them into the roller 31, so that the peppers fall onto the surface of the harvesting plate 33. The harvesting screw 34 rotates, and the spiral ridges convey the peppers that have fallen onto the surface of the harvesting plate 33 to the harvesting conveyor belt 35, and finally transport them to the conveying module 4. This design improves harvesting efficiency by using a roller 31 for harvesting, while avoiding fruit damage and increasing the harvest rate.

[0024] Specifically, the harvesting module 3 includes a harvesting frame 36, which is fixedly connected to the front end of the frame 1; a harvesting plate 33 is fixedly connected between the two side walls of the harvesting frame 36; a roller 31 is rotatably connected to the two side walls of the harvesting frame 36 via a first rotating shaft 37, a first harvesting sprocket 38 is fixedly sleeved on one side of the first rotating shaft 37, the first harvesting sprocket 38 meshes with a first harvesting toothed chain 39, and the first harvesting toothed chain 39 also meshes with a second harvesting sprocket 310; the second harvesting sprocket 310 is fixedly sleeved on the surface of a second rotating shaft 311, and a first conveying wheel 312 and a third harvesting sprocket 313 are also fixedly sleeved on the surface of the second rotating shaft 311. The take-up sprocket 313 meshes with the second harvesting toothed chain 314, which in turn meshes with a fourth harvesting sprocket 315. The fourth harvesting sprocket 315 is fixedly sleeved on the surface of the third rotating shaft 316, and the surface of the third rotating shaft 316 is also fixedly sleeved with a harvesting screw 34. A fourth rotating shaft 317 is also provided between the two side walls of the harvesting frame 36, and a second conveyor wheel 318 is fixedly sleeved on the surface of the fourth rotating shaft 317. The surfaces of the first conveyor wheel 312 and the second conveyor wheel 318 are coupled to the harvesting conveyor belt 35. A motor output terminal is fixedly connected to any end of any of the first rotating shaft 37, the second rotating shaft 311, the third rotating shaft 316, or the fourth rotating shaft 317. By driving any one of the first rotating shaft 37, the second rotating shaft 311, the third rotating shaft 316, or the fourth rotating shaft 317 to rotate by a motor, the drum 31, the harvesting screw 34, and the harvesting conveyor belt 35 can be driven to move simultaneously, so that the harvesting module 3 can work as a whole.

[0025] The rear end of the harvesting plate 33 extends upward to the rear side of the roller 31, and the front end of the harvesting plate 33 extends upward to the front side of the harvesting screw 34. A conveying baffle 319 is provided at the end of the harvesting conveyor belt 35 away from the conveying module 4, and the surface of the harvesting conveyor belt 35 is provided with evenly spaced transverse ridges. This structure serves to prevent the chili peppers from being thrown off or rolling down, thus avoiding the chili peppers from being transported along the ideal path when the harvesting module 3 is working.

[0026] like Figure 6 and Figure 7As shown, the conveying module 4 includes a conveying box 41, the opening of which is adjacent to the transport end of the harvesting module 3. Sensors are installed on the side wall of the conveying box 41 to detect the stacking height of the chilies inside. A steering device is rotatably connected to the bottom of the conveying box 41, and a lifting device is fixedly connected to the bottom of the steering device, allowing the conveying box 41 to be raised, lowered, and rotated 90° around its bottom center to face the screening module 5. Chilies are transported from the end of the harvesting conveyor belt 35 of the harvesting module 3 to the conveying box 41. When the sensor detects that the chilies have accumulated to a certain height in the conveying box 41, the lifting device is activated to raise the conveying box 41, and then the steering device rotates the conveying box 41, aligning it with the starting end of the screening module 5, so that the chilies fall into the screening module 5. In practical use, an indicator light can also be added to the conveying box 41 to indicate its storage and working status.

[0027] The steering device includes a first steering gear 42 horizontally hinged to the center of the bottom of the conveyor box 41. A steering motor 43 is fixedly connected to the side wall of the conveyor box 41, and a second steering gear 44 is fixedly connected to the output end of the steering motor 43. The first steering gear 42 and the second steering gear 44 are meshed together. In use, when the motor is turned on, the second steering gear 44 rotates around the first steering gear 42, allowing the conveyor box 41 to rotate around the center of its bottom surface.

[0028] The lifting device includes a lifting platform 45 fixedly connected to the bottom of the first steering gear 42. The lifting platform 45 is fixedly connected to a lifting block 46. The lifting block 46 includes two limiting through holes 47 and one lifting screw hole 48. The lifting block 46 is slidably connected to a lifting limiting post 49 through the limiting through holes 47. The lifting block 46 is threadedly connected to a rotatable lifting stud 410 through the lifting screw hole 48. The lifting limiting post 49 and the lifting stud 410 are arranged in parallel. A horizontally arranged first lifting gear 411 is fixedly connected to the bottom of the lifting stud 410. The first lifting gear 411 is sequentially meshed with several second lifting gears 412. A lifting motor (not shown) is fixedly connected to each of the second lifting gears 412. In use, when the motor is turned on, the second lifting gears 412 drive the first lifting gears 411 to rotate, thereby driving the lifting stud 410 to rotate. At this time, the lifting block 46 rises or falls under the limit of the lifting limiting post 49, causing the conveyor box 41 to rise or fall.

[0029] like Figure 8As shown, the screening module 5 includes a sloping screening bar 51, which comprises several arranged bars 52, each of which can rotate downstream. A screening conveyor belt 53 is located at the end of the screening bar 51, with the end of the conveyor belt 53 facing outwards from the frame 1. In use, the chili peppers in the conveyor box 41 fall into the upstream section of the screening bar 51. Under the influence of gravity and the rotation of the bars 52, the chili peppers roll downstream along the screening bar 51, falling through the gaps between the bars 52 into the storage box 6 below. Debris such as branches and leaves are intercepted and transported to the screening conveyor belt 53, ultimately being discharged into the farmland.

[0030] Specifically, the screening bar 51 includes two parallel frames 54, with the bar members 52 arranged laterally between the frames 54. A screening gear 55 is fixedly fitted on one side of each bar member 52, and each screening gear 55 is sequentially meshed with the others. By driving any one of the frames 54 to rotate via a motor, all the frames 54 can rotate in the same direction. The diameter of the screening gear 55 can be customized, allowing the gap between the bars to be adjusted to harvest different varieties of chili peppers.

[0031] The screening conveyor belt 53 is driven by a motor, sprockets and toothed chain, and its structure is existing technology; the screening conveyor belt 53 is provided with transverse ribs and baffles similar to those in the harvesting module 3, and the above structure will not be described in detail here.

[0032] The storage box 6 is equipped with a sensor on its side wall to detect the height of the chili peppers piled up inside. A push-pull device is fixedly connected to the bottom of the storage box 6. This device includes a push-pull limiting post and a push-pull stud, and its principle is the same as the lifting device in the conveying module 4, so it will not be described in detail here. When the sensor detects that the chili peppers have piled up to a certain height inside the storage box 6, the push-pull device is activated to push the storage box 6 out from under the screening bar 51, making it easier for workers to handle.

[0033] like Figure 9 As shown, the crushing module 7 includes a disc blade 71 horizontally positioned at the front bottom of the frame 1, the disc blade 71 rotating around its center; a crushing conveyor belt 72 is located behind the disc blade 71, the upper surface of the crushing conveyor belt 72 moving backward; a grinding device is located behind the crushing conveyor belt 72, the grinding device including several horizontally arranged, rotatable grinding rods 73, with several grinding gears 74 fixedly fitted on each grinding rod 73, the grinding gears 74 on adjacent grinding rods 73 arranged alternately. In use, the disc blade 71 first cuts the harvested straw. As the harvester moves forward, the cut straw is rolled between the disc blade 71 and the frame 1, and transported by the crushing conveyor belt 72 to the top of the grinding device. The densely packed grinding gears 74 grind the straw into fragments, which are then scattered on the soil surface as fertilizer.

[0034] Specifically, the crushing conveyor belt 72 includes a plurality of crushing sprockets 75 arranged in an array in the horizontal direction. The crushing sprockets 75 are arranged longitudinally, and each row of crushing sprockets 75 meshes with a crushing toothed chain 76. A plurality of discontinuously arranged conveyor plates 77 are evenly arranged on the crushing sprockets 75. The discontinuous arrangement of the conveyor plates 77 makes it easier for the chopped straw to be rolled into the gaps between the conveyor plates 77, avoiding ineffective transportation due to insufficient friction between the straw and the conveyor plates 77.

[0035] The bottom rear side of the frame 1 is provided with a crushing frame 78, which is fixedly connected to a plurality of arranged transmission blocks 79. Each transmission block 79 is fixedly connected to a gear frame 710. The gear frame 710 is rotatably connected to a plurality of crushing rods 73. A crushing gear 74 is fixedly fitted at the front end of each crushing rod 73, and a first transmission gear 711 is fixedly connected to the rear end of each crushing rod 73. The transmission blocks 79 are rotatably connected to a plurality of transmission rods 712, and second transmission gears 713 are fixedly connected to both ends of each transmission rod 712. The first transmission gear 711 and the second transmission gear 713 mesh perpendicularly. The entire crushing device can be operated by driving any one of the crushing gears 74 to rotate via a motor.

[0036] The soil loosening module 8 includes two soil loosening frames 81 positioned opposite each other at the rear of the frame 1. A bucket frame 82 is rotatably connected to the inner side of each soil loosening frame 81, and several buckets 83 are staggered on the bucket frame 82. In this embodiment, the soil loosening frame 81 is driven by a motor and gears; its structure is existing technology and will not be described in detail here. In use, the motor is started, driving the bucket frame 82 to rotate, causing the staggered buckets 83 to continuously dig and loosen the ground soil, turning the straw fragments crushed by the crushing module 7 into the soil, preparing for subsequent sowing.

[0037] The chili harvester is also equipped with a controller 9, which, combined with computer software, can automatically control all motors and sensors of the harvester to achieve fully automatic operation. In practical use, this invention can also be equipped with a new energy module, by adding solar panels and energy conversion devices to the top of the conveying screw and conveying limit rod. This allows the harvester to absorb light energy during operation, providing power and being energy-saving and environmentally friendly.
