Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a fertilizer spreader. Background Art

[0002] With the improvement of agricultural production level, fertilizer spreader is a kind of equipment that replaces manpower to apply waste materials to the fields. Fertilizer spreader can improve the efficiency and accuracy of fertilization, and at the same time reduce environmental pollution during fertilization.

[0003] The existing utility model patent with announcement number CN 204168751 U and announcement date 2015.02.25 discloses a fertilizer spreader, wherein a transmission chamber with an accommodating cavity is provided at the front end of the material box, the transmission mechanism is installed in the accommodating cavity of the transmission chamber, one end of the feeding auger is rotatably supported at the rear end of the material box, and the other end of the feeding auger is rotatably installed at the front end of the material box and extends into the transmission chamber and is connected to the transmission mechanism; the fertilizer mechanism is installed at the discharge port, the fertilizer mechanism includes a cover shell with openings at both ends, a rotating shaft and a fertilizer plate, the cover shell is fixed to the side wall surface of the material box, one end of the rotating shaft is rotatably supported on the cover shell, the other end of the rotating shaft extends into the transmission chamber and is rotatably supported on the inner wall surface of the transmission chamber, and is connected to the transmission mechanism, one end of the fertilizer plate is fixed to the circumferential surface of the rotating shaft, and the other end of the fertilizer plate extends along the radial direction of the rotating shaft.

[0004] The fertilizer spreader of the utility model has the advantages of high fertilizing efficiency and no blockage during the fertilizing process;

[0005] However, in the actual agricultural production process, in order to simplify the production process as much as possible and reduce production costs, the patent exposes the following problem: the fertilizer spreader only has the function of fertilizing, and according to the actual production process, the fertilization process is often accompanied by trenching and covering. When using the fertilizer spreader, other equipment needs to be replaced when trenching and covering. This will cause the following problems: 1. Since equipment needs to be replaced when trenching and covering, it will take time to replace the equipment, resulting in a decrease in the overall production efficiency; 2. During production operations, the fertilizer spreader, trencher, and covering machine need to be transported to the site, resulting in an increase in transportation costs. The most important thing is that multiple equipment needs to be purchased, resulting in an increase in procurement costs.

[0006] Therefore, the utility model provides a fertilizer spreader for integrating the functions of trenching, fertilizing and soil covering, thereby reducing the cost of transportation and procurement and improving production efficiency.

[0007] A fixed displacement pump is one whose output flow rate is variable under the condition of constant speed, and vice versa. The biggest difference between them is that the shaft of the variable displacement pump is eccentrically installed. Simply put, after the speed of the fixed displacement pump is selected, its flow rate cannot be adjusted. The output flow rate of the variable displacement pump can automatically adjust the flow rate according to the pressure change of the system (the size of the external load), that is, the output flow rate is small when the pressure is high, and the output flow rate is large when the pressure is low. In this way, it can save the number of hydraulic components, thereby simplifying the oil circuit system and reducing oil heating. The disadvantages are severe flow pulsation, unstable system pressure, short pump life, easy damage to the pump bearings because it is eccentrically installed, and loud noise. Utility Model Content
