Description

Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to a straw and forage crushing vehicle. Background Technology

[0002] Currently, the main uses of agricultural straw include making biomass feed, compressing it for fuel, or crushing it and composting it into fertilizer. The first thing to do for these uses is to solve the crushing problem. Crushers are currently a relatively practical and convenient way to crush straw and forage.

[0003] For example, Chinese patent application number CN2015000498115.2 discloses a straw crushing vehicle, including a vehicle body, on which a crushing chamber is installed. The crushing chamber includes a straw inlet and a straw outlet, wherein the straw inlet is located on the top of the vehicle, and a crushing component is installed inside the crushing chamber. The crushing component is characterized in that the crushing component includes a rotating shaft and a support frame. The rotating shaft is fixed on the support frame. The input shaft of the rotating shaft is connected to an engine through a gearbox and is driven to rotate by the engine. A blade is installed on the rotating shaft, and a heater is provided inside the rotating shaft.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist:

[0005] The material inlet of common straw crushing vehicles is usually located on the top of the vehicle. Since the vehicle is more than 1.5 meters high, it is difficult for workers to stand on the ground and lift the material above the height of the material inlet during actual operation. This makes manual feeding inconvenient and hinders efficient operation. Utility Model Content

[0006] This application provides a straw and hay shredder to improve the following technical problems:

[0007] The material inlet of common straw crushing vehicles is usually located on the top of the vehicle. Since the vehicle is more than 1.5 meters high, it is difficult for workers to stand on the ground and lift the material above the height of the material inlet during actual operation. This makes manual feeding inconvenient and hinders efficient operation.

[0008] This application provides a straw and forage crushing vehicle, which adopts the following technical solution:

[0009] A straw and forage crushing vehicle includes a chassis and a cab. The cab is located at the front end of the chassis. A cargo box is mounted on the chassis. A partition is provided inside the cargo box, dividing the internal space into a material output chamber and a material crushing chamber. The material crushing chamber is located between the material output chamber and the cab. An opening is provided on one side of the material crushing chamber. A crusher is installed inside the material crushing chamber. The material inlet of the crusher is located at the bottom of the opening. The material outlet of the crusher is connected to a material lifting unit. A connecting port is provided at the top of the partition. The discharge port of the material lifting unit is located at the connecting port. The material lifting unit is used to lift the crushed material to the connecting port and drop it into the material output chamber. A material conveying mechanism is also provided in the material output chamber for sending the crushed material out from the rear of the cargo box.

[0010] In one feasible technical solution of this application, the material lifting unit includes a discharge blower and a vertically arranged lifting pipe.

[0019] By adding partitions inside the carriage, the internal space is divided into a material output chamber and a material crushing chamber, which are used to install the material conveying mechanism and the crusher, respectively. This effectively avoids interference between the two during operation and facilitates later maintenance and cleaning. The material inlet of the crusher is located relatively low, not exceeding 1 meter, which is only slightly higher than the height of the chassis support surface. This allows the operator to feed the material from the ground without having to lift the material too high. At the same time, a material lifting unit is added to the material crushing chamber to facilitate the smooth entry of the crushed material into the material output chamber. Then, the crushed material is sent out from the rear of the carriage through the material conveying mechanism. The overall structure of the equipment is more reasonable, easier to use, and suitable for agricultural promotion and application. Attached Figure Description

[0048] By adding a partition 4 inside the carriage 3, its internal space is divided into a material output chamber and a material crushing chamber, which are used to install the material conveying mechanism 7 and the crusher 5 respectively. This effectively avoids interference between the two during operation and is also conducive to later maintenance and cleaning. The material inlet 500 of the crusher 5 is located at a relatively low position, not exceeding 1 meter, which is basically slightly higher than the support surface of the chassis 1. This makes it convenient for workers to stand on the ground to perform feeding operations without having to lift the material too high, thus saving more effort. At the same time, a material lifting unit 6 is added to the material crushing chamber to facilitate the smooth entry of the crushed material into the material output chamber. Then, the crushed material is sent out from the rear of the carriage 3 through the material conveying mechanism 7. The overall structure of the equipment is more reasonable, easier to use, and suitable for agricultural promotion and application.
