Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and typical embodiments.

[0015] In Fig. 1 and Fig. 2, the main body of the topdressing machine with decompression and sand guiding function of the present invention is composed of a frame 1, a sandbox 2 that takes out the sand outlet, a powered conveyor belt 3 and a roller brush 4. The sandbox 2 is set on the frame 1, the conveyor belt 3 is set on the bottom of the sandbox 2, and the roller brush 4 is set under the sand outlet of the sandbox 2, which is characterized in that the bottom of the sandbox 2 is located above the conveyor belt 3 A decompression sand guide grid plate 5 composed of a middle main board 6 and a surrounding frame 7 is installed, and the middle main board 6 is composed of a front and rear unidirectional inclined side 8 and a front and rear unidirectional inclined side 8. A number of small grids 10 formed by reinforcing ribs 9 are formed. A handle 11...

Abstract

The invention relates to a sand spreader with pressure reduction sand guiding function, composed of a frame, a sand box with a sand outlet, a transmission band driven by power and a rolling brush, wherein the sand box is on the frame, the band is through arranged on the bottom of the box, the brush is arranged under the sand outlet, the chamber of the box near the bottom and above the band is arranged horizontally with a pressure-reducing sand guiding grid plate with an inclined side surface, a middle main board formed by connected a plurality of small grids made from strength bars between the inclined surface, and a frame with a lifter and a limit buckle, since the inclined face can bear part load of sliding sand, while the sand direction is in an angle with the band, the sliding sand can generate a co-direction pushing force on the band to improve the feeding ability of the transmission band, reduce real bearing pressure, improve load of the box, improve spreading efficiency and improve the service life of the band.

Description

technical field [0001] The invention relates to the technical field of agricultural and forestry machinery and equipment, in particular to a sand topdressing machine with a decompression and sand guiding function suitable for use in golf courses, football fields, lawn production bases and the like. Background technique [0002] Sand topdressing machine is a mechanized operating device with sand-carrying and sand-dressing functions specially used for maintaining and maintaining sports grounds and lawns. Currently, various types of sand topdressing machines on the market are mainly produced in the United States, Japan, the Netherlands and China. They are all composed of a frame, a sandbox with a sand outlet, a power-driven conveyor belt and a roller brush. Loads directly into the sandbox above the conveyor belt. When working, the conveyor belt must bear all the pressure of the sand in the sand box, and slowly move and circulate through the bottom of the sand box under the tra...
