Description

Technical Field

[0001] This utility model relates to a farmland preparation and sowing device, and more specifically, to a straw clearing device suitable for wide and narrow row sowing of corn. Background Technology

[0002] In agricultural production, the wide-narrow row planting pattern for maize is widely used due to its advantages such as improved ventilation and light penetration, enhanced fertilizer efficiency, and increased yield. However, current sowing operations face many challenges: Regarding straw management, traditional seed-line straw cleaning methods easily cause blockages in narrow rows, affecting machine passage and sowing quality, and can interfere with drip irrigation tape laying in no-till drip irrigation areas; in terms of sowing accuracy, ground-wheel driven seeders are prone to slippage, leading to uneven sowing, and the adjustment of seed spacing is cumbersome, making it difficult to meet complex agronomic needs; monitoring sowing status is difficult, and abnormalities such as double-seeding and missed sowing are hard to detect in a timely manner; traditional sowing depth measurement is inefficient and inaccurate, affecting seed germination and seedling growth. Therefore, there is an urgent need to develop a straw cleaning device suitable for wide-narrow row maize sowing. Summary of the Invention

[0003] The purpose of this invention is to provide a straw cleaning device suitable for wide and narrow row planting of corn. This device can crush and clean up the stubble in narrow rows, thereby improving planting efficiency.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a stubble-cleaning device suitable for wide and narrow row planting of corn, comprising a frame, a splined shaft, a transmission box, a transmission shaft assembly, a gear assembly, a side plate, a cutter shaft, a cutter holder, a stubble-cleaning cutter, a pin, a guide plate, a rubber plate, a crossbar, a baffle, a fertilizing device, and a planting device; the frame is the frame of the stubble-cleaning device; the transmission box is installed above the frame; the left end of the transmission shaft assembly is installed on the right side of the transmission box; the right end of the transmission shaft assembly is installed on the side plate; the gear assembly is installed on the right end of the side plate; the cutter shaft is installed on the side plate; the cutter holder is installed on the cutter shaft corresponding to the narrow row; the stubble-cleaning cutter is installed in the cutter holder hole through a pin; the guide plate is installed on the frame; the rubber plate is installed below the guide plate; the crossbar is installed on the side plate; the baffle is installed on the crossbar; the fertilizing device and the planting device are sequentially installed behind the frame.

[0005] Furthermore, a stalk cleaning device suitable for corn planting in both wide and narrow rows is characterized by: symmetrically arranged blade holders on the blade shaft corresponding to the narrow rows, with adjacent blade holders spaced 120 degrees apart; no blade holders on the blade shaft corresponding to the wide rows; each blade holder is equipped with only one stubble-cleaning blade using an L-shaped sling cutter that is not fixed; the stubble-cleaning blades are arranged in groups in a forward and reverse spiral pattern on the blade holder corresponding to the narrow rows, and the blade holders are connected to the positioning holes on the stubble-cleaning blades by pins, and the stubble-cleaning blades do not contact the ground when working.

[0006] Furthermore, a straw cleaning device suitable for wide and narrow row planting of corn is characterized by: a V-shaped guide plate installed behind the stubble-cleaning blade shaft corresponding to the narrow row, mounted on the frame behind the stubble-cleaning blade shaft; after the stubble-cleaning blade breaks the stubble, it throws the stubble onto the guide plate, thereby ensuring that the stubble is thrown into the wide row and that the narrow row is free of stubble; a rubber plate is attached below the guide plate, and when the machine is running, the rubber plate is kept close to the ground to prevent the stubble from being thrown backward.

[0007] The beneficial effects of this utility model are that it can achieve the stubble-cleaning knife to crush and clean up the wheat straw in the narrow rows during sowing, and through the guide plate, the crushed wheat straw in the narrow rows is cleaned into the wide rows, so that the corn sowing is smooth and uniform, the drip irrigation tape is laid smoothly, and the corn sowing efficiency and sowing quality are guaranteed.

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings: Figure 1As shown, a stubble-cleaning device suitable for wide-narrow row planting of corn includes a frame 101, a splined shaft 102, a transmission box 103, a transmission shaft assembly 104, a gear set 105, a side plate 106, a cutter shaft 107, a cutter holder 108, a stubble-cleaning cutter 109, a pin 110, a guide plate 111, a rubber plate 112, a crossbar 113, a baffle 114, a fertilizer applicator 200, and a planting device 300; the frame 101 is the frame of the stubble-cleaning device; the transmission box 103 is fixedly installed on top of the frame 101; the left end of the transmission shaft assembly 104 is fixedly installed on the right side of the transmission box 103; The right end of the drive shaft assembly 104 is mounted on the side plate 106 via a bearing; the gear assembly 105 is fixedly mounted on the right end of the side plate 106; the cutter shaft 107 is mounted on the side plate 106 via a bearing; the cutter holder 108 is mounted on the cutter shaft 107 corresponding to the narrow row; the stubble-cleaning cutter 109 is mounted in the cutter holder hole via a pin; the guide plate 111 is mounted on the frame 101; the rubber plate 112 is mounted below the guide plate 111; the crossbar 113 is mounted on the side plate 106; the baffle 114 is mounted on the crossbar 113; the fertilizer applicator 200 and the seeding applicator 300 are sequentially mounted behind the frame 101.

[0013] Working Principle: The transmission box 103 is fixedly installed above the frame 101, serving as the power hub and connecting to an external power source (such as the tractor's power take-off shaft). When the tractor starts, power is transmitted to the transmission box 103 via the splined shaft 102. After the transmission box 103 changes speed and direction, the power is output to the transmission shaft assembly 104. The transmission shaft assembly 104 acts as a power transmission bridge, stably transmitting power to the gear set 105. The gear set 105 receives power from the transmission shaft assembly 104 and transmits it to the cutter shaft 107 through gear meshing. The cutter shaft 107 can rotate flexibly. The stubble-cleaning blade 109 forms a linkage structure with the cutter shaft 107. When the cutter shaft 107 rotates at high speed under the drive of the gear set 105, the stubble-cleaning blade 109 rotates at high speed accordingly. Its sharp cutting edge cuts and crushes the wheat straw in the narrow row, breaking the straw into small pieces. During the high-speed rotation and pulverization of straw by the stubble-clearing blade 109, centrifugal force is used to fling the pulverized stubble towards the wider rows. Some of the stubble flying behind the blade shaft 107, with the cooperation of the rear guide plate 111 and rubber plate 112, ensures that there is no straw residue in the narrow row sowing area, creating conditions for subsequent sowing and drip irrigation tape laying. After the narrow row straw clearing and stubble relocation are completed in the stubble-clearing section, the fertilization device 200 and the sowing device 300, installed sequentially behind the frame 101, begin operation. The fertilization device 200 is electrically driven, evenly spreading fertilizer in the narrow row soil after stubble clearing according to the preset amount. The sowing device 300 is electrically driven, reducing missed and repeated sowing rates, and improving sowing efficiency and accuracy. To facilitate adjustment of corn kernel spacing, satellite speed measurement control and ground wheel speed measurement electric control seed metering disc are used to achieve stepless adjustment of the corn sowing speed between 6 km / h and 10 km / h.

[0014] This embodiment is merely an illustration of the concept and implementation of this utility model, and is not intended to limit it. Under the concept of this utility model, the technical solution without substantial changes is still within the scope of protection.
