Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to an adjustable mud removing device for a pressure roller of a seeder. Background Art

[0002] Since the reform and opening up, the national economy has grown rapidly, and "scientific and technological innovation and independent innovation" have become the mainstream of domestic industrial development. my country's industry is gradually developing in the direction of intensive, energy-saving, emission-reducing and low-carbon. The pressing roller is a commonly used agricultural machinery component. Its main function is to press the soil after ridge formation, sowing and fertilization to increase the density and firmness of the soil, thereby preventing the soil from losing moisture too quickly, protecting the soil moisture, maintaining the ground temperature, and creating a suitable seedbed environment for seed germination and emergence. However, the pressing rollers currently used will more or less adhere to the soil during the pressing operation. As the amount of adhered soil increases, not only the pressing surface is uneven, but also the seeds are uneven in depth, and sometimes even the seeds are adhered out. The shovel plates used for mud removal of the seeding machine pressing rollers commonly used on the market are mostly integral. Clay congestion often occurs during use. The operator needs to stop the machine frequently to manually remove the clay during operation, which not only increases the workload of the operator and reduces the operating efficiency, but also seriously affects the germination and emergence of seeds. Utility Model Content

[0003] The utility model aims to provide an adjustable seed drill pressing roller mud removal device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable seeder pressing roller mud removing device, comprising a base plate, the base plate is connected to a U-shaped wire by bolts, a support pile is welded on the surface of the base plate opposite to the U-shaped wire, the mud removing base plate is sleeved on the support pile, a threaded column is fixed on the support pile, an adjustment nut is provided on the threaded column, the threaded column passes through the mud removing base plate, an adjustment spring is fixed under the adjustment nut, the end of the adjustment spring away from the adjustment nut is fixedly connected to the mud removing base plate, and a mud removing plate is provided on the mud removing base plate through a mud removing plate fixing wire.

[0005] Preferably, the tail end of the desilting bottom plate has an inclined angle.

[0006] Preferably, the demudifier plate is a smooth iron sheet.

[0007] Preferably, the bottom plate is provided with limiting fixing columns on both sides of the mud removal bottom plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are: by adjusting the tightness of the spring by adjusting the nut, the tightness of the contact between the mud removal base plate and the pressing roller is changed, so that mud can be removed from soils of different hardness; secondly, multiple devices are installed on the connecting square pipe of the pressing roller mud removal device to realize a split type. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 2 It is a side view of the utility model.

[0011] In the figure: 1. U-shaped wire; 2. Support pile; 3. Adjustment nut; 4. Adjustment spring; 5. Demudifier plate fixing wire; 6. Demudifier plate; 7. Demudifier bottom plate; 8. Bottom plate. DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] Please refer to 1-2. An embodiment of the utility model provided by the utility model: an adjustable seeder pressing roller mud removing device, including a base plate 8, a U-shaped wire 1 is connected to the base plate 8 by bolts, a support pile 2 is welded on the surface opposite to the U-shaped wire 1, a mud removing base plate 7 is sleeved on the support pile 2, a threaded column is fixedly provided on the support pile 2, an adjusting nut 3 is provided on the threaded column, the threaded column passes through the mud removing base plate 7, an adjusting spring 4 is fixedly provided below the adjusting nut 3, the end of the adjusting spring 4 away from the adjusting nut 3 is fixedly connected to the mud removing base plate 7, a mud removing plate 6 is provided on the mud removing base plate 7 through a mud removing plate fixing wire 5, the device is fixed to the connecting square tube of the pressing roller mud removing device by the U-shaped wire 1, a plurality of springs can be arranged on the connecting square tube according to the length of the pressing roller, the compression strength of the adjusting spring 4 is adjusted by adjusting the nut 3, so that the adjusting spring 4 squeezes the mud removing base plate 7, thereby adjusting the force between the mud removing plate 6 and the soil, and realizing mud removal with different strengths for soils of different hardness.

[0014] The tail end of the demudging bottom plate 7 has an inclined angle, which is convenient for shortening the distance between the demudging plate 6 and the pressing roller to perform demudging.

[0015] The mud removal plate 6 is a smooth iron sheet, which makes the mud removal effect better.

[0016] Limit fixing columns are fixed on both sides of the bottom plate 8 to facilitate the movement of the mud removal bottom plate 7 when the mud removal bottom plate 7 is subjected to the force generated by the soil and the pressure roller, and the position of the mud removal bottom plate 7 is relatively fixed by the limit fixing columns.

[0017] Working principle: During use, different soil geology and viscosity are different. When the soil is loose, the friction is small. By adjusting the 3 adjusting nuts of the device to reduce the tightness of the 4 adjusting springs, adjust the tightness of the demud plate 6 and the demud bottom plate 7 with the pressing roller, so that each set of devices has the same contact tightness with the pressing roller, allowing the pressing roller to rotate freely; when the soil is more viscous, by adjusting the 3 adjusting nuts to reduce the tightness of the 4 adjusting springs, adjust the tightness of the demud plate 6 and the demud bottom plate 7 with the pressing roller, allowing the pressing roller to rotate freely, so that the pressing roller can achieve the purpose of effective leveling.
