Description

Technical Field

[0001] The utility model relates to the field of agricultural liquid spraying, in particular to a nutrient solution spraying device used in the feeding process of a wrapping machine. Background Art

[0002] During the alfalfa wrapping process, harvested and crushed alfalfa is piled on a cement platform to dry in the sun. It is then dumped into the front bucket of a wrapping machine using a forklift. The wrapping machine's baling mechanism then bundles the alfalfa into cylindrical bundles. Finally, the wrapping machine's wrapping mechanism wraps the alfalfa into bales. Before wrapping, a nutrient solution containing beneficial bacteria (lactic acid bacteria), also known as bacterial solution, is sprayed onto the alfalfa. This airtight barrier allows the bacterial solution to ferment within the bales, inhibiting the fermentation of putrefactive bacteria and reducing nutrient loss.

[0003] The current method is to manually use a pump to spray directly into the front bucket of the wrapping machine. However, the front bucket area is large, and it is difficult to spray evenly by hand. In addition, the bacterial liquid needs to be sprayed continuously during the wrapping process. However, manual spraying with a bucket has a small container and the spraying volume cannot be effectively and continuously sprayed. Frequent additions are required, and when the spraying is stopped, the alfalfa that is still being wrapped is not sprayed with the bacterial liquid. Utility Model Content

[0004] The purpose of the utility model is to provide a nutrient solution spraying device used in the feeding process of a wrapping machine.

[0005] The utility model is implemented by the following technical solutions:

[0006] A nutrient solution spraying device for use in the feeding process of a wrapping machine, comprising a liquid tank, a water pump, a liquid spraying pipe, a hose, an H-shaped bracket, a front bucket of the wrapping machine, a liquid level sensor, a PLC controller, and a power control switch of the wrapping machine;

[0007] The water inlet of the water pump is connected to the liquid tank through a pipe passing through the top of the liquid tank, the water outlet of the water pump is connected to one end of the hose, and the other end of the hose is connected to one end of the liquid spray pipe through a valve;

[0008] The H-shaped bracket is fixed on the casing above the outlet of the front bucket, the liquid spraying pipe is fixed to the bottom of the H-shaped bracket, and a nozzle is provided at the bottom of the liquid spraying pipe;

[0009] The liquid tank is provided with the liquid level sensor, the signal output end of the liquid level sensor is connected to the signal input end of the PLC controller, and the PLC controller is electrically connected to the power control switch and the water pump respectively.

[0010] Preferably, a roller is provided for rotation at the bottom of the liquid tank; and a liquid inlet is provided at the top of the liquid tank.

[0011] The advantages of this utility model are as follows: when alfalfa is transported in the front bucket of the wrapping machine, it is evenly sprayed with bacterial liquid by multiple nozzles spread out in sequence, saving labor; when the amount of bacterial liquid is insufficient, it can also sense and interlock the wrapping machine and water pump to stop in time, avoiding the alfalfa from being continuously packaged without being sprayed with bacterial liquid.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1 、 Figure 2 、 Figure 3 As shown, a nutrient solution spraying device for the feeding process of a wrapping machine includes a liquid tank 1, a water pump 2, a liquid spraying pipe 3, a hose 5, an H-shaped bracket 7, a front bucket 8 of the wrapping machine, a liquid level sensor 9, a PLC controller 10, and a power control switch 11 of the wrapping machine;

[0019] A liquid inlet 13 is provided at the top of the liquid tank 1, through which bacterial liquid can be introduced into the liquid tank 1. The water inlet of the water pump 2 is connected to the liquid tank 1 through a pipe passing through the top of the liquid tank 1. The water outlet of the water pump 2 is connected to one end of a hose 5, and the other end of the hose 5 is connected to one end of a liquid spray pipe 3 through a valve 6. The water pump 2 pumps the bacterial liquid in the liquid tank 1 from the hose 5 to the liquid spray pipe 3; closing the valve 6 facilitates the removal of the hose 5, which is beneficial for separating the wrapping machine from the liquid tank 1, so that the wrapping machine is not interfered with by the liquid tank 1 when it is moved; the end of the hose 5 can be connected to the valve 6 through a pipe joint for easy disassembly and assembly.

[0020] The H-shaped bracket 7 is fixed on the casing above the outlet of the front bucket 8, and the spray pipe 3 is fixed at the bottom of the H-shaped bracket 7. A nozzle 4 is provided at the bottom of the spray pipe 3. Before the alfalfa is sent away by the conveyor of the front bucket 8 and enters the baling mechanism, it is sprayed with the bacterial liquid evenly sprayed from the spray pipe 3 to the nozzle 4.

[0021] A liquid level sensor 9 is provided in the liquid tank 1. The signal output end of the liquid level sensor 9 is connected to the signal input end of the PLC controller 10. The PLC controller 10 is electrically connected to the power control switch 11 and the water pump 2 respectively. When the amount of bacterial liquid in the liquid tank 1 is insufficient, the liquid level sensor 9 senses it and sends a signal to the PLC controller 10. The PLC controller 10 issues a control instruction to shut down the power control switch 11 and the water pump 2.

[0022] There is a roller 12 at the bottom of the liquid tank 1, and the liquid tank 1 is easy to move by the roller 12.

[0023] Working principle: When the utility model is in use, as the alfalfa is conveyed from the conveyor of the front bucket 8 to the baling mechanism, the water pump 2 draws the bacterial liquid in the liquid tank 1 from the hose 5 to the spray pipe 3, and then sprays it evenly onto the alfalfa from multiple nozzles 4 spread out in sequence. As the alfalfa is baled and wrapped, the bacterial liquid is mixed into the straw bale.

[0024] When the amount of bacterial liquid in the liquid tank 1 is insufficient, the liquid level sensor 9 sends a signal to the PLC controller 10, which controls the power control switch 11 and the water pump 2 to turn off, and the wrapping machine and the water pump 2 stop working. The alfalfa is not sprayed with liquid and the transportation is also stopped, so as to prevent the alfalfa from being packaged without being sprayed with bacterial liquid.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
