AI Technical Summary
The push plates on both sides of the loader's manure shovel cannot move simultaneously and sway left and right, resulting in low cleaning efficiency and inconvenient operation.
Multi-channel valves and diverting current collectors are used to connect the oil cylinders on the left and right sides. The oil flow of the large and small chambers of the oil cylinder is controlled through the diverting current collector, so as to achieve synchronous action of the push plate and prevent swaying through hydraulic locks.
The synchronous action of pushing the plates on both sides of the manure shovel is realized, which improves the efficiency of ranch cleaning and reduces the labor intensity of the operator.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of loaders, in particular to a synchronous control system for left and right push plates of a dung shovel used for a loader. Background Art
[0002] With the development of animal husbandry, the number of large-scale farms is increasing. In order to ensure the living environment of livestock, it is necessary to clean up the manure in time. Using a loader with a manure shovel can save labor costs.
[0003] Currently, most of the manure pushing shovels used in loaders on the market use oil cylinders on the left and right sides to control the push plates on both sides, and are directly operated by the third link of the loader. However, due to the uneven distribution of manure on both sides during use, the push plates on both sides cannot be opened and closed synchronously and cannot swing left and right, resulting in the channel being unable to be cleaned, and the operator needs to make repeated adjustments, which has the disadvantages of low manure pushing efficiency and inconvenience in use. Utility Model Content
[0004] The utility model provides a synchronous control system for left and right pushing plates of a manure pushing shovel for a loader, which can solve the problems pointed out in the background technology.
[0005] A synchronous control system for the left and right push plates of a manure shovel for a loader includes a multi-way valve and left and right oil cylinders. A diverter and collector valve is provided on the oil circuit between the multi-way valve and the left and right oil cylinders. The oil port at one end of the diverter and collector valve is connected to the A port of the multi-way valve, and the two oil ports at the other end are respectively connected to the large chambers of the left and right oil cylinders. The B port of the multi-way valve is respectively connected to the small chambers of the left and right oil cylinders.
[0006] Preferably, a hydraulic lock is provided on the oil circuit between the diverter and collector valve and the left and right oil cylinders.
[0007] Beneficial effect: The utility model provides a synchronous control system for the left and right push plates of a manure shovel for a loader. The system can solve the problem that the push plates on both sides of the manure shovel cannot move synchronously and swing left and right, thereby improving the efficiency of manure pushing work in the ranch and reducing labor intensity.

[0009] Description of reference numerals:
[0010] Numbers in the figure: multi-way valve 1; oil cylinder 2; flow diverter and collector valve 3; hydraulic lock 4. DETAILED DESCRIPTION
[0011] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.
[0012] Example 1:
[0013] like Figure 1 As shown, a synchronous control system for the left and right push plates of a loader dung shovel includes a multi-way valve 1 and left and right oil cylinders 2. A diverter and collector valve 3 is provided on the oil circuit between the multi-way valve 1 and the left and right oil cylinders 2. The oil port at one end of the diverter and collector valve 3 is connected to the A port of the multi-way valve 1, and the two oil ports at the other end are respectively connected to the large chambers of the left and right oil cylinders 2. The B port of the multi-way valve 1 is respectively connected to the small chambers of the left and right oil cylinders 2. The specific multi-way valve 1 is generally a triple multi-way valve, that is, the oil port at one end of the diverter and collector valve 3 is connected to the A port of the multi-way valve 1. The third joint A port of the multi-way valve 1 is connected, and the third joint B port of the multi-way valve 1 is respectively connected to the small chambers of the left and right oil cylinders 2. When the multi-way valve 1A port discharges oil, the left and right oil cylinders 2 large chambers enter oil, and the diverter and collector valve 3 is used to control the oil flow rate of the left and right oil cylinders 2 large chambers to be the same, thereby realizing the synchronous movement of the push plates on both sides; when the multi-way valve 1B port discharges oil, the left and right oil cylinders 2 small chambers enter oil, and the large chambers return oil, and the diverter and collector valve 3 is used to control the oil flow rate of the left and right oil cylinders 2 small chambers to be the same, thereby realizing the synchronous movement of the push plates on both sides.
[0014] In some embodiments, a hydraulic lock 4 is provided on the oil circuit between the diversion and collection valve 3 and the left and right oil cylinders 2. The hydraulic lock 4 is respectively connected to the large cavity and the small cavity of the left and right oil cylinders 2 to prevent the dung shovel push plate from swinging left and right due to external force.
[0015] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
