Description

Technical Field

[0001] This application belongs to the field of agricultural machinery technology, specifically relating to a hand-push type pond-dredging device. Background Technology

[0002] The flue-cured tobacco industry is a vital pillar of Yunnan Province's agriculture. Tobacco cultivation is a crucial means and pathway to increase workers' income and promote rural economic development, playing a significant role in consolidating poverty alleviation achievements and realizing rural revitalization. However, due to Yunnan's unique topography, some tobacco-growing areas suffer from weak infrastructure, making it difficult for large machinery to operate effectively in mountainous and plateau terrain. Furthermore, the limited weight and efficiency of some small agricultural machines hinder their widespread adoption. This results in low levels of mechanization and high labor intensity for workers in the current tobacco cultivation process.

[0003] For the pit-digging stage in flue-cured tobacco planting, the current method uses a backpack pit-digging machine. This requires workers to carry the pit-digging engine on their backs and hold the drill bit in their hands, using only their arm strength to press down and lift the drill bit to dig the pits. While the backpack pit-digging machine improves efficiency to some extent compared to manual pit-digging, holding the drill bit still requires considerable physical exertion, meaning the worker's workload is not effectively reduced. Furthermore, when using the backpack pit-digging machine, workers need to stand to the side of the tobacco pit, and under this high workload, there is a risk of losing control of the drill bit, potentially leading to accidents.

[0020] In view of this, a hand-push type pit-dredging device is provided according to an embodiment of this application, such as... Figure 1 , Figure 2 As shown, it includes a frame body 1, rollers, a drilling engine 2, a drilling drill bit 3, and a pressing structure; the rollers are installed at the bottom of the frame body 1; the drilling engine 2 is mounted on the frame body 1 and is connected to the drilling drill bit 3 via a drive shaft 21; the pressing structure is located at the top of the frame body 1 and is used to press down or lift the drilling drill bit 3; the drilling drill bit 3 is connected below the pressing structure.

[0021] Specifically, in practical work, the pit-drilling device is placed above the tobacco mound, with the rollers positioned in the flue ditches on both sides of the mound and the pit-drilling drill bit 3 directly above the mound. The pit-drilling engine 2 is started, and the device is pushed to the desired pit-drilling position. The pressing mechanism is then lowered, causing the drill bit 3 to drill into the soil and complete the pit-drilling. After the pressing force is released, the drill bit 3 is lifted by the pressing mechanism. The device is pushed to the next desired pit-drilling position, and the above actions are repeated until all pit-drilling work on the tobacco mound is completed.

[0022] Preferably, in specific embodiments, such as Figure 2As shown, the pressing mechanism includes a crossbar 41, a stroke rod 42, a connecting rod 43, and a reset component; the stroke rod 42 is vertically disposed at the top of the frame body 1; a sleeve 44 is connected to the crossbar 41, and the sleeve 44 is slidably sleeved on the stroke rod 42; one end of the connecting rod 43 is connected to the crossbar 41, and the other end is connected to the pit drilling bit 3; the reset component is disposed between the crossbar 41 and the frame body 1, and is used to assist in lifting the pit drilling bit 3.

[0023] Preferably, in specific embodiments, such as Figure 2 As shown, the reset component includes a spring 45; the spring 45 is sleeved on the stroke rod 42 and is located between the sleeve 44 and the frame body 1.

[0024] Furthermore, in one embodiment, such as Figure 2 As shown, there are two stroke rods 42, which are respectively arranged on the top two sides of the frame body 1 along the first direction; there are two sleeves 44, which are respectively connected to the two ends of the crossbar 41 and are fitted onto the two stroke rods 42 in a corresponding manner; the first direction is the direction perpendicular to the forward direction of the frame body 1.

[0025] Specifically, the sliding connection between the sleeve 44 and the stroke rod 42 limits the movement direction of the drilling bit 3, and the length of the spring 45 controls the drilling depth.

[0026] Furthermore, in one embodiment, the dredging engine 2 is disposed at the front of the frame body 1 in the forward direction; the pressing structure is disposed at the rear of the frame body 1 in the forward direction.

[0027] Specifically, the pressing structure is located at the rear of the frame 1 in the forward direction, which enables the operator behind the device to accurately locate the pit-making position and facilitates operation.

The bottom of the frame 1 and the pit-drilling bit 3 are both located above and close to the top of the soil mound. Under the weight of the crossbar 41, the spring 45 ensures that the pit-drilling bit 3 is positioned close to the top of the soil mound; and when compressed to its maximum under external force, it drives the pit-drilling bit 3 to penetrate the soil to a pit depth of 15-20 cm.
