Embodiment Construction
[0021] Such as Figure 1-4 As shown, this specific embodiment adopts the following technical scheme: a preparation device for crop straw feed, including a straw storage bin 1 and a discharge port 2, and a discharge port is installed on the bottom of one side of the straw storage bin 1 2. It also includes a material lifting conveyor 3, a hopper 4, a straw crushing chamber 5, a straw powder mixing chamber 6, and a mobile screening and blanking device 7. A material lifting conveyor is installed on one end of the discharge port 2 3. A feed hopper 4 is installed at one end of the material lifting conveyor 3, and the bottom of the feed hopper 4 is installed on the top of the straw crushing chamber 5, and a straw powder mixing chamber is installed at the bottom of the straw crushing chamber 5 6. A mobile screening and blanking device 7 is installed between the straw powder mixing chamber 6 and the straw crushing chamber 5, and a crushing motor 8 is installed inside the straw crushing...

The invention discloses a crop straw feed preparation device. The crop straw feed preparation device comprises a straw storage chamber, a discharging port, a material elevating conveyor, a feeding hopper, a straw smashing chamber, a straw powder mixing chamber and a movable screening and discharging device. A discharging port is mounted at the bottom of one side of the straw storage chamber. Conveying stability of the preparation device is effectively improved, particle size uniformity of straw feed can be guaranteed by vibratory screening and discharging, spaces of the straw smashing chamberand the straw powder mixing chamber are adjusted by the movable screening and discharging device, a sufficient smashing space of the smashing chamber is guaranteed at an early stage of straw feed preparation by down moving of the movable screening and discharging device, and a sufficient mixing space of the mixing chamber is guaranteed in a late stage of straw feed preparation by upward moving ofthe movable screening and discharging device, so that space utilization efficiency of the preparation device is improved, the size of the preparation device is reduced, and cost and occupied area of the straw feed preparation device are reduced.
Description
Technical field: [0001] The invention relates to the technical field of agricultural machinery, in particular to a preparation device for crop straw feed. Background technique: [0002] Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource that contains more water and sugar. It is a good feed material, especially corn straw, wheat straw and so on. Straw can be prepared into straw feed by crushing and mixing additives. However, in the existing straw feed preparation device, the preparation of crushing and preparation of the mixture are carried out in the crushing device and th...
