Abstract
Abstract A transfer assembly of a belt conveyor comprises a discharge drum of the conveyor rigidly secured on a frame at the discharge end of the conveyor. Also on the discharge end of the conveyor is hinged a deflector shield which has a curvilinear portion whose concavity faces the discharge drum and is located after the drum along the conveyor belt movement. The shield has an entry portion located before the discharge drum along the conveyor belt movement. A support is secured rigidly to the frame at the discharge end of the conveyor. Two rods are hinged by first ends to the support, the rods being positioned one after the other along the conveyor belt. The other ends of the rods are hinged to the shield so that the distance between the first ends does not exceed the distance between the other ends of the rods.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
220 words
A transfer assembly of a conveyor belt extending in a longitudinal direction, comprising: a rigid frame means; a discharge end of the conveyor; a discharge drum of the conveyor, said discharge drum being rigidly secured to said frame means at said discharge end of the conveyor; a deflector shield means hinged to said frame means on said discharge end of the conveyor, said deflector shield means having a curvilinear portion whose concavity faces said discharge drum and is located after said discharge drum along the conveyor belt travel; said deflector shield means having an entry portion located before said discharge drum upstream along the conveyor belt; a support means rigidly secured to said frame means at said discharge end of the conveyor; at least two rods spaced from each other in said longitudinal direction and downstream with respect to the conveyor belt, and each hinged at one end to said deflector shield means and at an opposite end to said support means in order to ensure hinged suspension of said shield means from said frame means; and said rods being connected to said support means and said deflector shield means so that said entry portion of said deflector shield means rises faster than said curvilinear portion in response to the transporting of large pieces of transported material on said conveyor.
Claim 2
Dependent Claim
220 words
A transfer assembly of a conveyor belt extending in a longitudinal direction, comprising: a rigid frame means; a discharge end of the conveyor; a discharge drum of the conveyor, said discharge drum being rigidly secured to said frame means at said discharge end of the conveyor; a deflector shield means hinged to said frame means on said discharge end of the conveyor, said deflector shield means having a curvilinear portion whose concavity faces said discharge drum and is located after said discharge drum along the conveyor belt travel; said deflector shield means having an entry portion located before said discharge drum upstream along the conveyor belt; a support means rigidly secured to said frame means at said discharge end of the conveyor; at least two rods spaced from each other in said longitudinal direction and downstream with respect to the conveyor belt, and each hinged at one end to said deflector shield means and at an opposite end to said support means in order to ensure hinged suspension of said shield means from said frame means; and said rods being connected to said support means and said deflector shield means so that said entry portion of said deflector shield means rises faster than said curvilinear portion in response to the transporting of large pieces of transported material on said conveyor.
Claim 3
Dependent Claim
30 words
A transfer assembly as claimed in claim 1, wherein the entry portion of said shield means is made curvilinear and has its concavity facing said discharge end of the conveyor.
Claim 4
Dependent Claim
30 words
A transfer assembly as claimed in claim 1, wherein said rod which is located first along the conveyor belt is shorter than the rod located second along said conveyor belt.
Claim 5
Dependent Claim
18 words
A transfer assembly as claimed in claim 1, wherein said rods are provided with a length adjustment device.
