Description

Technical Field

[0001] The invention relates to a furrowing device for a sugarcane planter, in particular to a W-shaped double-furrow furrowing device for a sugarcane planter. Background Art

[0002] At present, the amount of sugarcane planted in my country is second only to India and Brazil, and it is showing an increasing trend year by year. The main sugarcane production areas are Yunnan and Guangxi. Guangxi has always ranked first in the country in sugarcane planting, accounting for 60% of the national sugarcane planting share, and Yunnan Province ranks second, accounting for 18% of the national sugarcane planting share. With the increase of national urbanization efforts, the labor force in some sugarcane planting areas has gradually been exported to cities, and the labor cost has increased sharply, which has also increased the difficulty of improving the economic profit of sugarcane planting. At the same time, it is also urgently needed to develop and promote the mechanization of sugarcane planting. Therefore, people are now beginning to use sugarcane planting machines to plant sugarcane.

[0003] At present, most of the furrow opener components of mechanized sugarcane planters use plowshare furrow openers. The plowshare furrow opener has a simple structure and fewer parts, but it has the following disadvantages: the plowshare furrow opener opens a V-shaped row furrow, thereby planting one row of sugarcane, the number of planting rows is small, and the work efficiency is low. In addition, the plowshare furrow opener has a bulky structure and cannot act on soil with too high hardness, otherwise the shape of the furrow is difficult to guarantee, especially when the traction resistance is large during operation, the opened row furrow cannot form a V-shaped row furrow due to the return mud, thereby affecting the planting quality of sugarcane. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a W-shaped double-ditch furrowing device for sugarcane planters. The furrowing device has furrowing knives symmetrically arranged in four directions along both sides of a transmission chain. It can not only act on soil with high hardness, solving the problem that the traction resistance is too large to open a furrow during work, but also can open a W-shaped double furrow, thereby realizing double furrow opening and greatly improving work efficiency.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A W-shaped double-ditch type furrowing device for a sugarcane planter comprises a furrowing bracket, one end of the furrowing bracket is provided with an input shaft, the other end of the furrowing bracket is provided with an output shaft, the input shaft and the output shaft are both provided with transmission gears, a transmission chain matched and connected thereto is provided between the two transmission gears, the transmission chain is provided with knife seats along both sides of each chain section, the knife seats on the same chain section are provided with soil loosening knives arranged facing each other or trenching knives arranged back to back, and the soil loosening knives and trenching knives are arranged at intervals, and the soil loosening knives and trenching knives both comprise a straight knife arranged on the knife seat and an arc-shaped curved knife arranged on the straight knife.

[0007] As a preferred technical solution, in order to ensure that there is a certain inclination between the two grooves opened at the same time, to ensure the shape of the grooves, to ensure the strength of the groove opening knife and to extend its service life, the angle between the curved blade and the straight blade of the groove opening knife is 105°.

[0008] As a preferred technical solution, in order to ensure a firm connection between the transmission gear and the transmission chain, thereby ensuring the normal operation of the loosening knife and the furrowing knife, ensuring that the shape of the W-shaped double furrow is intact, which is beneficial to improving the planting quality of sugarcane, a tension adjuster is provided on the furrowing bracket for adjusting the engagement between the transmission gear and the transmission chain.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The trenching device has trenching knives symmetrically arranged in four directions along both sides of the transmission chain. It can not only act on soil with high hardness, solving the problem of being unable to trench due to large traction resistance during work, but also can trench W-shaped double trenches, realize double trenching, and greatly improve work efficiency.

[0011] 2. The shape of the trenching knife is set scientifically and reasonably to ensure that there is a certain inclination between the two trenches opened at the same time, to ensure the shape of the trench, and at the same time to ensure the strength of the trenching knife and extend its service life.

[0012] 3. Set the tensioning adjuster to ensure a firm connection between the transmission gear and the transmission chain, thereby ensuring the normal operation of the loosening knife and the furrowing knife, and ensuring that the shape of the W-shaped double furrow is intact, which is beneficial to improving the planting quality of sugarcane.

[0022] like Figure 1 The figure shows a specific embodiment of the present invention, a W-shaped double-ditch type sugarcane planter furrowing device, comprising a frame-shaped furrowing bracket 1, one end of the furrowing bracket 1 is provided with an input shaft 2, and the other end is provided with an output shaft 3, and the input shaft 2 and the output shaft 3 are both provided with a transmission gear 4. In this embodiment, the input shaft 2 and the output shaft 3 are both provided with fastening wheels 10 located on both sides of the transmission gear 4, and the fastening wheels 10 are connected to the furrowing bracket 1. A transmission chain 5 is provided between the two transmission gears 4 and is connected thereto. Figure 2 As shown, the transmission chain 5 is provided with a knife seat 6 on both sides of each chain section, and the knife seat 6 on the same chain section is provided with a loosening knife 7 arranged opposite to each other or a trenching knife 8 arranged opposite to each other. In this embodiment, the horizontal distance between the trenching knives 8 on both sides is set to 400mm, and the distance between the double grooves in the W shape is also 400mm. Figure 4 As shown, the loosening knife 7 and the trenching knife 8 are arranged at intervals, and the loosening knife 7 and the trenching knife 8 both include a straight knife arranged on the knife seat 6 and an arc-shaped curved knife arranged on the straight knife, as shown in FIG. Figure 3 As shown, in order to ensure the strength of the knife and increase its service life, the loosening knife 7 and the trenching knife 8 are integrally formed in this embodiment, and the loosening knife 7 arranged opposite to each other is located in the same plane as the transmission chain 5. Therefore, the loosening knife 7 is only used to dig up the soil between the two trenching knives on the same section of the chain. This embodiment does not limit the angles of the curved knife and the straight knife on the loosening knife 7.

[0023] The angle between the curved blade and the straight blade of the trenching knife 8 is 105°, so the vertical distance between the highest point of the double grooves in the W shape and the bottom of the groove is 100 mm. Figure 5 As shown, in order to ensure that there is a certain inclination between the two grooves opened at the same time, the shape of the planting groove is ensured, and at the same time the strength of the groove opening knife 8 is ensured to extend its service life.

[0024] The ditching bracket 1 is provided with a tensioning adjuster 9 for adjusting the meshing of the transmission gear 4 and the transmission chain 5. The tensioning adjuster 9 is mainly realized by a threaded adjustment rod to ensure a firm connection between the transmission gear 4 and the transmission chain 5, thereby ensuring the normal operation of the loosening knife 7 and the ditching knife 8, ensuring that the shape of the W-shaped double ditch is intact, which is beneficial to improving the planting quality of sugarcane.

[0025] When the present invention is used: install the trenching device in the following manner: Figure 6 and Figure 7 The sugarcane planter shown in the figure includes a frame 11, a transmission 12 is provided in the middle of the front end of the frame, the furrowing device is detachably mounted on both sides of the frame 11 and is located between the transmission 12, a sugarcane storage box 13 is provided on the frame 11, a fertilizer component 14 located in the middle of the frame 11 is provided between the two furrowing devices, and power transmission components 15 connected to the furrowing device and the fertilizer component 14 are provided at both ends of the transmission 12, and a soil covering shovel 16, a film covering component 17 and a pressing wheel 18 are provided in sequence behind the furrowing device and the sugarcane storage box 13.

[0026] When working, the sugarcane planter is connected to a four-wheel tractor with more than 120 horsepower. According to the depth of the trenching, the trenching device is installed on the frame 11 at a certain angle, and the height of the sugarcane planter hanging on the tractor is adjusted. The trenching depth can be from 200 to 500 mm. In this embodiment, the angle between the trenching device and the frame 11 is set to 50°, so the depth of the trench is 400 mm. The transmission 12 transmits power from both sides to the power transmission component 15, and then transmits it to the two trenching devices and the fertilizer component 14. The tractor drives the planter in the forward direction, and the trenching device can open a W-shaped double trench in the soil. Figure 4 As shown, the sugarcane seeds then fall from the sugarcane storage box 13 into the row ditch, as shown in FIG. Figure 5 As shown, the fertilizer flows from the fertilizer applying component 14 through the guide pipe into the row ditch, and the soil covering shovel 16 pushes the soil back into the row ditch to cover the sugarcane, thus completing the process of trenching, planting, fertilizing and soil covering.
