Description

Technical Field

[0001] This utility model belongs to the field of peanut cultivation technology, specifically relating to a peanut digging, turning, and drying device. Background Technology

[0002] Peanuts, as a widely cultivated oilseed and cash crop globally, occupy an important position in my country's agricultural production system. Their yield and quality directly impact farmers' economic benefits and the supply of edible oils in the market. The complete peanut harvesting process requires two key operations: first, the peanut plant, along with its mature pods, must be completely excavated from the soil, taking care to prevent the pods from falling off or breaking due to improper digging force or angle, ensuring stable attachment of the pods to the vines; second, immediately after excavation, the peanut plant must be turned over, flipping the pods from their downward-facing, soil-closed position to an upward-facing position. This prevents the pods from prolonged contact with damp soil or moisture generated by accumulated vines, thus preventing mold growth and spoilage, and ensuring post-harvest quality. The efficiency and continuity of these two steps are crucial for shortening the peanut harvesting cycle and mitigating the risks of agricultural delays (such as pod spoilage caused by rainfall during harvest), especially in large-scale, intensive farming scenarios where these needs are even more urgent.

[0003] Currently, the methods for peanut digging and vine-turning drying mainly fall into two categories: First, for small-scale planting plots, manual operation remains the primary method. Farmers manually dig up peanut plants using simple tools such as hoes and shovels, then turn the vines over one by one and arrange them neatly for drying. This method is not only labor-intensive and time-consuming, but also prone to problems such as missed peanuts and incomplete vine turning due to limitations in manual operation precision and physical strength, resulting in low drying efficiency and failing to meet the pace requirements of modern large-scale agricultural production. Second, to improve operational efficiency, mechanized equipment has gradually emerged in the industry. Among them, the existing technology closest to the technical field of this utility model and with the most similar application scenario is the "Peanut Digging, Turning, and Drying Machine" disclosed in Chinese Invention Patent (Patent No.: 202410286346.6). This existing equipment integrates multiple independent transmission modules (such as multiple sets of gear transmission and chain transmission components) and execution components (such as separate digging shovels and independent turning rollers) to achieve the digging and turning functions, resulting in a redundant overall structure and complex assembly relationships. This not only leads to higher manufacturing costs for the equipment, increasing farmers' initial purchase costs, but also increases the difficulty of installation and debugging due to the complex structural design. Daily use requires professional personnel to handle component wear, troubleshooting, and maintenance, further increasing farmers' subsequent usage costs and operational barriers.

[0004] In addition, the overall operating speed of the equipment is limited, and it can only process a small area of ​​peanut fields per unit time. The efficiency of the operation is far from meeting the "rush harvesting" requirements of large-scale planting. Especially during the agricultural window when peanuts need to be harvested in a short period of time after they mature, the inefficiency of the existing equipment will directly cause farmers to miss the best harvest time and increase the risk of fruit spoilage. Utility Model Content

[0005] The purpose of this invention is to provide a peanut digging, turning, and drying device to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A peanut digging, turning, and drying device includes a drive mechanism, a screw conveyor mechanism, a soil turning mechanism, and a frame. The drive mechanism is mounted on the frame and is used to drive the frame to travel. The soil turning mechanism is connected to the front end of the frame and is used to turn the peanut vines out of the soil. The screw conveyor mechanism is fixed to the rear end of the frame and is used to gather the turned-up peanut vines to one side of the furrow for drying.

[0008] The drive mechanism includes a diesel engine, a fuel tank, a support frame, a support shaft, a drive sprocket, and a driven sprocket. The diesel engine is fixedly mounted on the load-bearing surface of the vehicle frame. The fuel tank is detachably mounted at the fuel supply interface of the diesel engine. The power output end of the diesel engine is connected to a flywheel coaxially fixed at one end of the support shaft via a belt. The support shaft is rotatably mounted in the bearing seats of the support frame via bearings at both ends. The bottom of the support frame is fixedly connected to the load-bearing surface of the vehicle frame. The drive sprockets are coaxially fixed at both ends of the support shaft. The drive sprockets are driven by meshing with the driven sprockets via a chain. The driven sprockets are coaxially fixed at the power input end of the screw conveyor mechanism.

[0009] The spiral conveying mechanism includes a spiral auger and a housing; the bottom of the housing is fixedly connected to the bearing surface at the rear end of the frame, the middle section of the spiral auger is placed in the internal cavity of the housing, and the two ends of the spiral auger are rotatably connected to the end plates of the housing through bearings, and the driven sprockets are coaxially fixed to the two protruding ends of the spiral auger.

[0010] The soil turning mechanism includes at least one soil turning shovel, the top of which is fixedly connected to the frontmost crossbeam of the vehicle frame via a connector.

[0011] A push handle is fixedly connected to the rear crossbeam of the chassis. The push handle integrates a throttle that is electrically or mechanically connected to the diesel engine fuel control terminal. The throttle is used to adjust the output power of the diesel engine to control the speed of the chassis.

[0012] Preferably, the number of soil-turning shovels is 2-4, and each soil-turning shovel is evenly spaced along the length of the front crossbeam of the vehicle frame, and the top of each soil-turning shovel is detachably connected to the front crossbeam of the vehicle frame by bolts.

[0013] Preferably, the outer shell and the rear bearing surface of the frame are detachably connected by welding or bolts, the outer rings of the bearings at both ends of the spiral auger are interference-fitted with the bearing holes of the outer shell end plate, and the inner rings of the bearings are interference-fitted with the extended ends of the spiral auger.

[0014] Preferably, the support frame includes two parallel vertical rods and a horizontal rod connecting the tops of the two vertical rods. The bottom of the vertical rods is welded or bolted to the load-bearing surface of the vehicle frame. Bearing seat mounting holes are opened on the horizontal rod at the positions corresponding to the support shaft. The outer rings of the bearings at both ends of the support shaft are interference-fitted with the bearing seat mounting holes on the horizontal rod, and the inner rings of the bearings are interference-fitted with the support shaft.

[0015] Preferably, the pusher includes two upwardly inclined connecting rods and a gripping rod connecting the tops of the two connecting rods. The bottoms of the two connecting rods are welded or bolted to the rear crossbeam of the vehicle frame.

[0017] The beneficial effects of this utility model are as follows: This peanut digging, turning, and drying device integrates the drive mechanism, spiral conveyor mechanism, soil turning mechanism, and frame to achieve integrated operation of peanut digging, turning, and centralized drying. It effectively replaces the traditional manual digging and turning method, significantly reducing farmers' labor intensity and labor costs. Simultaneously, it avoids problems such as missed digging and incomplete turning that easily occur in manual operation, ensuring the quality of peanut harvesting. Compared to existing complex peanut digging and turning equipment, this device has a simple transmission path (only through the core transmission link of diesel engine-belt-sprocket-spiral auger), and clear component connections. This not only reduces equipment manufacturing costs and subsequent maintenance difficulty but also reduces power transmission losses and improves the coordination efficiency of each actuator. This allows the equipment to quickly complete peanut digging and centralized drying in a more stable operating state, significantly increasing the working area per unit time. It helps farmers efficiently complete the harvest within the agricultural window and reduces the risk of mold growth due to delayed drying.

[0018] Furthermore, the device features a throttle-equipped push handle at the rear of the frame, allowing operators to precisely control the equipment's speed directly. This adapts to varying soil hardness and peanut planting densities, enhancing operational convenience. Structural designs such as the secure connection between the tilling shovel and the frame, and the bearing fit between the auger and the outer casing, ensure that components are less prone to loosening or jamming during long-term operation, extending the equipment's lifespan. Overall, this device balances efficiency, convenience, and durability, effectively addressing current pain points in peanut harvesting. It provides a highly adaptable mechanized solution for both large-scale and small-scale peanut cultivation, helping to improve post-harvest peanut quality and farmers' economic benefits.

[0021] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0022] like Figure 1 As shown, a peanut digging, turning, and drying device includes a drive mechanism 1, a screw conveyor mechanism 2, a soil turning mechanism 3, and a frame 4. The drive mechanism is used to drive the entire frame to move. The soil turning mechanism is used to turn the peanut vines out of the soil. The screw conveyor mechanism is used to gather the turned-up peanut vines to one side of the furrow for drying.

[0023] The drive mechanism includes a diesel engine 11, a fuel tank 12, a support frame 13, a support shaft 14, a drive sprocket 15, and a driven sprocket 16. The diesel engine is fixed to the vehicle frame, the fuel tank 12 is mounted on the diesel engine, and the power end of the diesel engine is connected to a flywheel 17 on the support shaft via a belt. The support shaft is mounted on the support frame via bearings, and the support frame is fixed to the vehicle frame. The drive sprocket is fixed to both ends of the support shaft, and the drive sprocket is connected to the driven sprocket via a chain. The driven sprocket is mounted on the screw conveyor mechanism.

[0024] The screw conveyor mechanism is fixed to the rear end of the vehicle frame;

[0025] The spiral conveying mechanism 2 includes a spiral auger 21 and a housing 22. The spiral auger is housed inside the housing and connected to it via bearings. The driven sprockets 16 are fixed to both ends of the spiral auger. When the diesel engine starts, it drives the spiral auger to rotate, thereby concentrating the peanut vines to one side.

[0026] The soil-turning mechanism 3 includes a soil-turning shovel 31, with at least one shovel located at the front end of the frame. The frame is driven by a diesel engine, and the soil-turning shovel turns the peanut vines out of the soil.

[0027] A pusher 5 is fixed to the rear of the frame. When in use, start the diesel engine, hold the pusher, and use the throttle on the pusher to control the speed of the frame. The front soil-turning shovel turns up the peanut vines, and then the rear spiral auger automatically gathers the peanut vines to one side for drying.

[0028] The operator starts the diesel engine 11 fixed on the frame 4. The fuel tank 12 supplies power to the diesel engine. Its power end drives the flywheel 17 on the support shaft 14 to rotate through the belt. The support shaft 14 rotates under the support of the support frame 13. The drive sprockets 15 at both ends rotate accordingly and drive the driven sprockets 16 at both ends of the spiral conveyor 21 through the chain, so that the spiral sprocket 21 rotates stably in the outer shell 22. At the same time, the diesel engine drives the frame 4 to move forward, completing the power transmission and the start of the device's movement.

[0029] As the vehicle frame 4 moves forward, the foremost soil-turning shovel 31 inserts into the soil, turning the peanut vines up. The turned-up vines move with the vehicle frame to the rear-end spiral conveyor mechanism 2. The rotating spiral auger 21 uses the thrust of its spiral blades to uniformly concentrate the peanut vines on one side of the furrow, ensuring the peanuts face upwards for drying. The operator holds the push handle 5 on the rear of the vehicle frame, controlling the vehicle's speed and direction via the throttle on the handle, ensuring continuous and efficient operation. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
