Description

Technical Field

[0001] The utility model relates to the field of silage harvesting equipment, in particular to a heating anti-blocking system for an arc-shaped throwing barrel of a silage harvester. Background Art

[0002] Silage refers to the fresh stems and leaves of plants used as feed. Under the general background of "grain to feed", silage is an ideal feed for feeding livestock such as dairy cows, beef cattle and sheep. When used to feed livestock, in order to avoid waste, the silage is generally crushed before feeding to the livestock. The ensiled feed has good palatability, high nutrient retention rate and long storage time, and is deeply loved by domestic livestock farms and breeders.

[0003] Silage is made by using a silage harvester to crush and cut the material into short pieces, and then process, seal, store and ferment it. Common silages include corn, bean straw and forage grass. The structure of the silage harvester mainly includes a header, a feeding device, a chopping device, a throwing barrel, a silo, etc. Its work can be divided into the header cutting stage, the clamping feeding stage, the chopping stage, the cutting and pushing stage, the throwing and blowing stage and the silo gathering stage. In the throwing and blowing stage, the harvester's mechanical knife provides sufficient speed for the chopped material and throws it along the inner wall of the throwing barrel to the gathering bin. Since the material will constantly collide and rub against the inner wall of the throwing barrel during the throwing process, the fine material will adhere to the connection gap and arc section of the throwing barrel. Over time, the sticky blocks will become larger, which will hinder the smooth throwing of the material and increase the risk of clogging the throwing barrel. Moreover, when silage corn is harvested, its moisture content is as high as 65-75%, especially for silage harvesters equipped with grain crushing devices. After the corn grains are crushed, the sugar content of the material is further increased, making the possibility of sticking greater, resulting in blockage of the throwing barrel. Utility Model Content

[0004] The utility model provides a heating anti-blocking system for an arc-shaped throwing barrel of a silage harvester, aiming to solve the problem that materials are easily adhered in the throwing barrel of the existing harvester, resulting in blockage.

[0005] To achieve its purpose, the utility model adopts the following technical solutions:

[0006] A heating and anti-blocking system for an arc-shaped throwing barrel of a silage harvester, wherein the arc-shaped throwing barrel comprises a first throwing barrel, a second throwing barrel and a third throwing barrel which are sequentially connected to a chopping device of the harvester, the first throwing barrel is provided with a steering barrel, the free end of the third throwing barrel is connected with a discharge guide plate, the outer wall of the third throwing barrel is provided with a first heating plate, the top of the discharge guide plate is provided with a second heating plate, and the connection between the second throwing barrel and the third throwing barrel is provided with a third heating plate; the first throwing barrel, the steering barrel, the second throwing barrel and the third throwing barrel are all provided with temperature sensors, the temperature sensors are electrically connected to the signal input end of a controller, the signal output end of the controller is respectively electrically connected to the display screen and the signal input end of a control relay, and the signal output end of the control relay is respectively electrically connected to the first heating plate, the second heating plate and the third heating plate.

[0007] Furthermore, the first section of the throwing cylinder and the steering cylinder are connected through a first flange and a second flange, and a fourth heating plate is provided between the first flange and the second flange.

[0008] Furthermore, the fourth heating plate is electrically connected to the signal output terminal of the control relay.

[0009] Furthermore, the thickness of the first heating plate, the second heating plate, the third heating plate and the fourth heating plate are all 3-5 mm.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The heating anti-blocking system provided by the utility model softens the adhesive in the arc-shaped throwing barrel by installing the first heating plate, the second heating plate and the third heating plate at different positions of the arc-shaped throwing barrel. On the one hand, it can be quickly thrown out under the drive of the material flow of the throwing barrel, and on the other hand, it can be conveniently and quickly peeled off during maintenance. For the first section throwing barrel and the steering barrel connected by the first flange and the second flange, by setting the fourth heating plate between the first flange and the second flange, the adhesive at the connection joint position can be softened and dropped, preventing the adhesive block from becoming larger and causing blockage.

[0012] 2. The heating anti-blocking system provided by the utility model increases the surface temperature of the bonding part of the throwing barrel through heating by the heating plate, softens the material bonded to the inner wall of the throwing barrel, and enables the high-speed material flow to bring the bonded material out of the throwing barrel. Moreover, heating by the heating plate reduces the adhesion between the material and the barrel wall, reduces the possibility of the material bonding to the inner wall of the throwing barrel, thereby reducing the risk of blocking the throwing barrel and extending the maintenance cycle of the throwing barrel.
