Novel lotus root digging machine water pump

Abstract

The invention relates to the field of lotus root digging machines and provides a novel lotus root digging machine water pump. The novel lotus root digging machine water pump is characterized by comprising a pump body, a water drawing pipe and a water outflow pipe; the water drawing pipe comprises a main water drawing pipe body and auxiliary water drawing pipe bodies, and the auxiliary water drawing pipe bodies are arranged on the main water drawing pipe body at a certain distance; a transmission shaft is arranged in the pump body, blades, filter nets, a partition plate, a primary impeller, a fixed supercharging disc and a secondary impeller are sequentially arranged on the transmission shaft in the water inflow direction, the filter nets are connected with the partition plate, the primary impeller is arranged in the fixed supercharging disc, the secondary impeller is arranged on the water outflow side of the fixed supercharging disc, and a first bearing, a second bearing, a shaft sleeve and an oil seal are arranged on the transmission shaft; a water channel is formed in the pump body and connected with the water outflow pipe; an auxiliary water drawing pipe body support is 1 / 4 of the main water drawing pipe body, a user can select the proper water drawing pipe bodies according to the water level of a lotus root field, when one water drawing pipe body is blocked, due to the water pressure difference, water in the main water drawing pipe body can flow into the auxiliary water drawing pipe bodies, the blockage position is burst through, and the purpose of automatically clearing away blockage objects is achieved.

Description

technical field [0001] The invention relates to the field of lotus root digging machine equipment, and specifically provides a novel lotus root digging machine water pump. Background technique [0002] The nutritional value of lotus root is high, and it is deeply loved by people. Therefore, its planting area and area are constantly increasing. Although lotus root is easy to plant and manage, it is difficult to dig when harvesting. Because the silt in the lotus root field is very heavy and the lotus root needs to be excavated to minimize the breakage of the lotus root to ensure its good market value, manual excavation is not only labor-intensive, but also has a high breakage rate and low labor efficiency, which cannot meet the needs of the market. , so mechanized operations have become an inevitable trend. [0003] Existing lotus root digging machine has limitations in use, and when the water surface is lower than 20CM, the water pipe just cannot draw water or is very prone ...

[0002] The nutritional value of lotus root is high, and it is deeply loved by people, so its planting area and area are increasing. Although lotus root is easy to plant and manage, it is difficult to dig when harvesting

Because the silt in the lotus root field is very heavy and the lotus root needs to be excavated to minimize the breakage of the lotus root to ensure its good market value, manual excavation is not only labor-intensive, but also has a high breakage rate and low labor efficiency, which cannot meet the needs of the market. , so mechanized operations have become an inevitable trend

[0003] The existing lotus root digging machine has limitations in use. When the water surface is lower than 20CM, the water pipe cannot pump water or it is very prone to blockage
